source: git/ChangeLog@ 669d5d5

Tue Jul 09 11:14:28 GMT 2013  Olly Betts <olly@survex.com>

        * doc/TODO.htm: Update.

Tue Jul 09 10:31:50 GMT 2013  Olly Betts <olly@survex.com>

        * src/img.h: Remove unnecessary include of "useful.h" in IMG_HOSTED
          mode.

Tue Jul 09 08:48:35 GMT 2013  Olly Betts <olly@survex.com>

        * src/cavern.h,src/img.h: Renumber STYLE_PASSAGE and STYLE_NOSURVEY so
          that the style constants we want to pass to img are contiguously
          numbered.

Sun Jul 07 13:03:56 GMT 2013  Olly Betts <olly@survex.com>

        * src/img.h: Just make fRead always int, eliminating IMG_HOSTED
          conditional.

Sun Jul 07 12:45:11 GMT 2013  Olly Betts <olly@survex.com>

        * src/extend.c,src/img.c,src/img.h: Repurpose the long unused fBinary
          parameter to img_open_write() as a flags parameter, and add
          img_FFLAG_EXTENDED to specify that this is an extended elevation,
          in place of appending " (extended)" to the title.  Internally we
          still append this to the title (and remove it upon reading), but in
          the 3d v8 format, the flags will be stored explicitly in the file.

Sun Jul 07 12:22:32 GMT 2013  Olly Betts <olly@survex.com>

        * src/img.h: Add comments for the lists of "Leg flags" and "Station
          flags".

Sun Jul 07 12:20:29 GMT 2013  Olly Betts <olly@survex.com>

        * NEWS,src/dump3d.c,src/img.h: Drop img_FLAG_NOSURVEY - it's redundant
          now we're going to store the style of each leg, and it hasn't yet
          been in a release.

Sun Jul 07 12:14:23 GMT 2013  Olly Betts <olly@survex.com>

        * src/dump3d.c: Report if the file is an extended elevation.

Sun Jul 07 12:12:24 GMT 2013  Olly Betts <olly@survex.com>

        * src/: Track the data style of each leg, and pass it in to img - it's
          not yet stored in the .3d file, but now it is easily available so it
          can be.

Fri Jul 05 13:17:24 GMT 2013  Olly Betts <olly@survex.com>

        * configure.ac,doc/3dformat-old.htm: Split off a copy of the current
          3dformat document - v8 will feature significant changes, so it will
          be clearer to document it separately.

Fri Jul 05 13:11:25 GMT 2013  Olly Betts <olly@survex.com>

        * src/dump3d.c,src/netskel.c: The fBinary parameter of img_open_write()
          has been unused for years, so stop passing fTrue.

Tue Jul 02 12:04:09 GMT 2013  Olly Betts <olly@survex.com>

        * src/img.c: Revert to putting a human readable timestamp string in
          v7 and older files.

Tue Jul 02 11:01:41 GMT 2013  Olly Betts <olly@survex.com>

        * src/dump3d.c: Show only 2 decimal places on coordinates and passage
          dimensions.

Wed Jun 12 13:35:21 GMT 2013  Olly Betts <olly@survex.com>

        * src/printwx.cc: Implement a copy ctor for BitValidator in the same
          way that wxGenericValidator does.  Older GCC seems to need such a
          copy ctor to exist to compile the uses of BitValidator in
          printwx.cc.

Wed Jun 12 13:34:52 GMT 2013  Olly Betts <olly@survex.com>

        * src/Makefile.am: Ship gdtconvert and gen_img2aven.

Wed Jun 12 13:33:38 GMT 2013  Olly Betts <olly@survex.com>

        * make_release: Tweak 'mingw' building to look for a suitable
          wx-config and get the C and C++ compilers to use using its
          --cc and --cxx flags.

Tue Jun 11 12:06:08 GMT 2013  Olly Betts <olly@survex.com>

        * src/printwx.cc: wxValidator subclasses shouldn't have a copy ctor,
          so give BitValidator an unimplemented private copy ctor, and use
          the normal ctor instead to implement the Clone() method.

Tue Jun 11 11:51:13 GMT 2013  Olly Betts <olly@survex.com>

        * NEWS: Update from ChangeLog.

Mon Jun 10 11:50:18 GMT 2013  Olly Betts <olly@survex.com>

        * lib/launchpad-merge-po: New script to eliminate unwanted differences
          introduced by launchpad.
        * lib/Makefile.am: Make launchpad-diff target use launchpad-merge-po
          and skip files missing in the launchpad export.

Mon Jun 10 11:47:37 GMT 2013  Olly Betts <olly@survex.com>

        * lib/unlaunchpad-po: Normalise dates in PO headers.

Mon Jun 10 07:23:07 GMT 2013  Olly Betts <olly@survex.com>

        * lib/Makefile.am,lib/unlaunchpad-po: Add "launchpad-diff" make target
          to assist with merging in translation changes from launchpad.

Sun Jun 09 00:04:37 GMT 2013  Olly Betts <olly@survex.com>

        * src/img.c: Handle .pos files containing unnamed stations - don't suck
          the next line in as the station name, and set img_SFLAG_ANON for
          them.

Sat Jun 08 15:12:25 GMT 2013  Olly Betts <olly@survex.com>

        * src/mainfrm.cc: Fix mapping of flags when loading a .3d file.

Sat Jun 08 15:07:05 GMT 2013  Olly Betts <olly@survex.com>

        * .gitignore,src/gen_img2aven: Commit script to generate img2aven.h.

Sat Jun 08 14:20:45 GMT 2013  Olly Betts <olly@survex.com>

        * lib/: Update line number references and merge message changes from
          survex.pot to the .po files.

Sat Jun 08 14:17:52 GMT 2013  Olly Betts <olly@survex.com>

        * lib/Makefile.am,lib/merge-po: Add "merge-pos" target to merge in new
          messages and updates to comments from survex.pot to the .po files.

Sat Jun 08 14:10:16 GMT 2013  Olly Betts <olly@survex.com>

        * tests/: Commit files for new tests.

Sat Jun 08 13:40:38 GMT 2013  Olly Betts <olly@survex.com>

        * src/img.c,src/img.h,src/mainfrm.cc: Store the 'processed at'
          timestamp in the .3d file as seconds since 1970 rather than as
          a human readable string.

Sat Jun 08 06:19:17 GMT 2013  Olly Betts <olly@survex.com>

        * src/commands.c: Correct comment about *alias.

Sat Jun 08 06:01:38 GMT 2013  Olly Betts <olly@survex.com>

        * lib/de.po,lib/de_CH.po,lib/en_US.po: Update translations.

Thu Jun 06 10:56:22 GMT 2013  Olly Betts <olly@survex.com>

        * lib/,src/: Show splay legs faded by default, with menu options to
          hide them or show them like other legs.

Tue Jun 04 12:37:03 GMT 2013  Olly Betts <olly@survex.com>

        * doc/manual.sgml,lib/survex.pot,src/,tests/Makefile.am,
          tests/cavern.tst: Add more anonymous station types - a double
          separator ('..' by default) is an anoymous wall point at the end
          of an implicit splay (c.f. '.' being a non-wall point), and
          a triple separator ('...' by default) is an anoymous point (with
          nothing special about the leg).  New *alias command allows '-' to be
          mapped to '..' to match pocket topo conventions.  3d file format now
          support a 'WALL' station flag.

Tue Jun 04 12:19:31 GMT 2013  Olly Betts <olly@survex.com>

        * src/Makefile.am: Regenerate gradient.pov is gdtconvert changes.

Sun Jun 02 12:51:46 GMT 2013  Olly Betts <olly@survex.com>

        * src/readval.c,tests/: Report column numbers as well as line numbers
          for more cavern errors and warnings.  Add more testcases.  If the
          argument to *include has an opening double quote but the closing
          double quote is missing, then skip trying to open the file.

Sun Jun 02 10:52:26 GMT 2013  Olly Betts <olly@survex.com>

        * src/cavernlog.cc: Remove useless extra quoting when invoking vim.

Fri May 31 13:51:16 GMT 2013  Olly Betts <olly@survex.com>

        * src/netskel.c: Use fputs not printf to write literal string to avoid
          GCC format security warning (the string can never contain a '%' but
          the compiler can't see that).

Fri May 31 13:08:01 GMT 2013  Olly Betts <olly@survex.com>

        * src/datain.c: Variable 'len' in compile_error_token was static for no
          good reason.

Fri May 31 12:32:22 GMT 2013  Olly Betts <olly@survex.com>

        * src/mainfrm.cc,src/mainfrm.h: Skip anonymous stations.

Fri May 31 12:17:56 GMT 2013  Olly Betts <olly@survex.com>

        * src/,tests/: Anonymous stations no longer have a made up unique name,
          and are marked with a new ANON flag in .3d files.

Mon May 27 11:24:18 GMT 2013  Olly Betts <olly@survex.com>

        * configure.ac: Update copyright date.

Sun May 26 13:05:34 GMT 2013  Olly Betts <olly@survex.com>

        * src/: New station flag SFLAGS_USED to mark a station as "used" so we
          don't issue "unused fixed point" warnings about it - previously we
          set 'shape' to be negative to indicate this, but that required us to
          handle that whenever we looked at or updated shape.

Sun May 26 11:47:06 GMT 2013  Olly Betts <olly@survex.com>

        * configure.ac: Fix sizeof(wxChar) test to work for wx2.9.

Fri May 10 05:55:54 GMT 2013  Olly Betts <olly@survex.com>

        * configure.ac,src/gla-gl.cc,src/glbitmapfont.h: It seems we need to
          include GL/gl.h before we can safely include GL/glext.h (at least on
          Debian wheezy).

Fri May 10 05:43:09 GMT 2013  Olly Betts <olly@survex.com>

        * configure.ac: Fix wxChar test to work in a non-cross-compiled build.

Wed May 08 22:38:56 GMT 2013  Olly Betts <olly@survex.com>

        * configure.ac,src/glbitmapfont.cc: Check sizeof(wxChar) at configure
          time, so we can avoid a warning when sizeof(wxChar)==2 (which is the
          case under mingw).

Wed May 08 05:54:23 GMT 2013  Olly Betts <olly@survex.com>

        * lib/en_US.po,lib/survex.pot: Update.

Tue May 07 23:30:26 GMT 2013  Olly Betts <olly@survex.com>

        * src/aven.cc: Don't crash trying to report an error after the app
          object has been created but before the frame window has.

Sun Jan 06 19:31:30 GMT 2013  Olly Betts <olly@survex.com>

        * doc/manual.sgml: "surface topology" -> "surface topography".

Sun Jan 06 08:07:22 GMT 2013  Olly Betts <olly@survex.com>

        * lib/Makefile.am: Remove launchpad-tarball target - changes now
          get picked up by launchpad automatically via a bzr mirror of the
          git repo.

Sun Jan 06 05:45:10 GMT 2013  Olly Betts <olly@survex.com>

        * lib/survex.pot,src/dump3d.c: Add --show-dates/-d to --help output.

Sun Jan 06 05:42:07 GMT 2013  Olly Betts <olly@survex.com>

        * lib/po-to-msg.pl: Fix matching quote check to really allow
          for using « and » in a translation.

Sun Jan 06 05:23:48 GMT 2013  Olly Betts <olly@survex.com>

        * src/dump3d.c: Report img_STOP as STOP rather than CODE_0xffffffff.

Thu Jan 03 01:08:28 GMT 2013  Olly Betts <olly@survex.com>

        * src/: Use wxValidator to simplify keeping svxPrintDlg member
          variables and fields in the dialog in sync.

Wed Jan 02 20:49:20 GMT 2013  Olly Betts <olly@survex.com>

        * src/gla-gl.cc,src/glbitmapfont.cc: Add checks for errors when reading
          the font file.

Wed Jan 02 20:48:22 GMT 2013  Olly Betts <olly@survex.com>

        * configure.ac,src/img.c: Avoid warning about redeclaration of round().

Wed Jan 02 09:11:41 GMT 2013  Olly Betts <olly@survex.com>

        * src/readval.c: Whitespace tweak.

Wed Jan 02 09:10:57 GMT 2013  Olly Betts <olly@survex.com>

        * src/netartic.c: Use TSTBIT(w, x) instead of w & BIT(x).

Wed Jan 02 09:10:30 GMT 2013  Olly Betts <olly@survex.com>

        * src/listpos.c: Fix compiler warning.

Wed Jan 02 09:04:58 GMT 2013  Olly Betts <olly@survex.com>

        * lib/survex.pot,src/,tests/: Add support for anonymous stations,
          which are indicated by a station name of '.'.

Sat Dec 29 18:50:07 GMT 2012  Olly Betts <olly@survex.com>

        * src/export.cc: Implement export of passage info for DXF (untested).

Sat Dec 29 05:29:31 GMT 2012  Olly Betts <olly@survex.com>

        * src/gfxcore.cc,src/printwx.cc,src/printwx.h: Default the export/print
          settings for passage related things to the "tubes" setting in the
          OpenGL view.

Sat Dec 29 05:11:20 GMT 2012  Olly Betts <olly@survex.com>

        * src/gfxcore.cc,src/gfxcore.h: Export of passage detail now works
          before we have displayed tubes in the OpenGL view.

Sat Dec 29 05:09:54 GMT 2012  Olly Betts <olly@survex.com>

        * src/avenprcore.cc,src/avenprcore.h,src/printwx.cc: Do away with the
          separate bool flags for each thing we can show in printing and export
          and just use the "show_mask" flags.

Fri Dec 28 23:30:55 GMT 2012  Olly Betts <olly@survex.com>

        * lib/: Fill in new messages from existing translations where possible.

Fri Dec 28 21:03:33 GMT 2012  Olly Betts <olly@survex.com>

        * lib/: Merge from survex.pot to .po files.

Fri Dec 28 22:21:50 GMT 2012  Olly Betts <olly@survex.com>

        * lib/survex.pot: Update locations.

Fri Dec 28 22:19:14 GMT 2012  Olly Betts <olly@survex.com>

        * src/printwx.cc: Disable passage-related export options when in a
          tilted view.  Hook up "Cross-sections" to printing on left and
          right markers.

Fri Dec 28 06:30:17 GMT 2012  Olly Betts <olly@survex.com>

        * lib/survex.pot,src/: Add options to export dialog to control showing
          cross-sections, walls and passages.

Fri Dec 28 05:53:56 GMT 2012  Olly Betts <olly@survex.com>

        * src/: Implement exporting of passages (ticket#4) for SVG.  Currently
          it is always on (I'll update the Export dialog shortly).

Wed Dec 26 22:21:10 GMT 2012  Olly Betts <olly@survex.com>

        * lib/survex.pot,src/commands.c,src/readval.c,src/readval.h,tests/: Add

Tue Dec 25 23:04:06 GMT 2012  Olly Betts <olly@survex.com>

        * src/readval.c,tests/: Demote errors about invalid dates to warnings,
          since we've accepted *date for ages without any checks on the value,
          and so existing datasets probably contain invalid dates and dates in
          other formats.  (ticket#19)

Tue Dec 25 22:03:20 GMT 2012  Olly Betts <olly@survex.com>

        * src/listpos.c: But always leave space for at least 4 digits, so we
          give exactly the same output as before unless we need the extra
          width.

Mon Dec 24 08:44:04 GMT 2012  Olly Betts <olly@survex.com>

Sun Dec 23 07:20:19 GMT 2012  Olly Betts <olly@survex.com>

Sun Dec 23 07:19:22 GMT 2012  Olly Betts <olly@survex.com>

        * lib/sk.po: Resolve a couple of inconsistencies in translation of
          similar messages by asking Martin Sluka.

Sun Dec 23 05:36:38 GMT 2012  Olly Betts <olly@survex.com>

        * NEWS: Update from ChangeLog.

Thu Dec 20 04:31:22 GMT 2012  Olly Betts <olly@survex.com>

        * lib/zh_CN.po: Translate another message.

Thu Dec 20 03:28:02 GMT 2012  Olly Betts <olly@survex.com>

        * lib/zh_CN.po: Add space after colon.

Thu Dec 20 03:26:15 GMT 2012  Olly Betts <olly@survex.com>

        * lib/survex.pot: Add more TRANSLATORS comments about terminology.

Thu Dec 20 03:25:45 GMT 2012  Olly Betts <olly@survex.com>

        * lib/it.po: Merge two new translations from launchpad.

Thu Dec 20 03:24:52 GMT 2012  Olly Betts <olly@survex.com>

        * lib/en_US.po: Correct "leg" to "shot" in a few places, and translate
          "Anticlockwise" to "Counterclockwise".

Wed Dec 19 10:41:55 GMT 2012  Olly Betts <olly@survex.com>

        * lib/po-to-msg.pl: Remove commented out code to find uses, which is
          now handled by a separate script.

Wed Dec 19 10:36:59 GMT 2012  Olly Betts <olly@survex.com>

        * lib/po-to-msg.pl: Update to read message numbers from references.

Tue Dec 18 12:00:40 GMT 2012  Olly Betts <olly@survex.com>

        * src/gla-gl.cc,src/gla.h: Update to use wxGLContext to avoid
          deprecation warnings from wx 2.9.

Tue Dec 18 11:40:34 GMT 2012  Olly Betts <olly@survex.com>

        * src/moviemaker.cc: Fix unused parameter warnings when we don't have
          libavformat available.

Tue Dec 18 11:39:40 GMT 2012  Olly Betts <olly@survex.com>

        * src/glbitmapfont.cc: Fix warning about ambiguous else from wxLogError
          macro.

Tue Dec 18 11:32:32 GMT 2012  Olly Betts <olly@survex.com>

        * INSTALL,lib/INSTALL.OSX,src/,survex.spec.in: Require at least
          wxWidgets 2.8.0 - it was released just over 6 years ago now,
          and the wx developers consider even 2.8 to be rather long in
          the tooth.  I haven't test build with wx 2.6 for more than a year
          and it's no longer packaged for Debian.  Dropping support for
          older wx allows a number of workarounds to be removed.

Tue Dec 18 11:05:24 GMT 2012  Olly Betts <olly@survex.com>

        * src/: Fix uses of some wx features which are deprecated in wx2.9.

Tue Dec 18 10:50:28 GMT 2012  Olly Betts <olly@survex.com>

        * src/gfxcore.cc,src/gla-gl.cc,src/gla.h: Fix OnSize handling
          so we can just call event.Skip() (which is the intended approach)
          rather than explicitly calling the parent class OnSize() method
          from the subclass OnSize() method.

Tue Dec 18 08:23:14 GMT 2012  Olly Betts <olly@survex.com>

        * src/aven.cc: Fix MSW build to not rely on a GCC extension.

Tue Dec 18 07:20:16 GMT 2012  Olly Betts <olly@survex.com>

        * lib/: Merge changes from template.

Tue Dec 18 07:06:41 GMT 2012  Olly Betts <olly@survex.com>

        * lib/,src/Makefile.am,src/gettexttomsg.pl: Eliminate po_codes and just
          store the message numbers as the line number in a fake source
          reference to file 'n'.

Tue Dec 18 04:13:18 GMT 2012  Olly Betts <olly@survex.com>

        * lib/po_codes,lib/survex.pot: Merge in updated source line numbers.

Tue Dec 18 04:11:09 GMT 2012  Olly Betts <olly@survex.com>

        * lib/extract-msgs.pl,src/Makefile.am: Don't include version in
          'Project-Id-Version'.

Tue Dec 18 03:13:16 GMT 2012  Olly Betts <olly@survex.com>

        * lib/: Set Project-Id-Version to just "survex" - the version part just
          complicates things unnecessarily for our usage.

Tue Dec 18 03:00:04 GMT 2012  Olly Betts <olly@survex.com>

        * tests/Makefile.am,tests/aven.tst: Add new testsuite script (aven.tst)
          which currently has regression tests for the recently fixed segfault
          when aven didn't have messages for the requested language.

Tue Dec 18 02:19:08 GMT 2012  Olly Betts <olly@survex.com>

        * src/message.c: Only use ASCII for the handful of hardcoded messages
          we need for errors loading message files, as it's probably more
          likely the wrong encoding will be set in such cases.

Tue Dec 18 02:02:57 GMT 2012  Olly Betts <olly@survex.com>

        * src/,tests/: Report column numbers as well as line numbers for some
          cavern errors and warnings, and update aven's cavern log parser to
          handle these.  Simplify handling of quantity lists to only recognise
          'DEFAULT' as the first item.  Add more testcases, expand some
          existing testcases, and expected output for more.

Mon Dec 17 22:19:21 GMT 2012  Olly Betts <olly@survex.com>

        * src/message.c: If we don't find the message file, only give an error
          if it was specified with SURVEX_LANG, since that is an explicit
          instruction to Survex, whereas LANG, LC_ALL and LC_MESSAGES are
          essentially system "preferred locale" settings.
        * src/aven.cc: Fix reporting of errors from message.c not to crash if
          the wxApp object hasn't yet been intitialised, and to convert the
          character encoding correctly.

Mon Dec 17 22:17:00 GMT 2012  Olly Betts <olly@survex.com>

        * lib/Makefile.am: Install zh_CN (Chinese) messages.

Mon Dec 17 22:02:43 GMT 2012  Olly Betts <olly@survex.com>

        * lib/zh_CN.po: Reuse existing translation of "Presentation" for the
          top level menu name - now all the whole menu bar is translated!

Mon Dec 17 11:07:00 GMT 2012  Olly Betts <olly@survex.com>

        * src/cavernlog.cc: Don't highlight a file:linenumber if there's no
          message after it, which avoids highlighting the "Included from"
          lines wrongly.

Mon Dec 17 11:04:36 GMT 2012  Olly Betts <olly@survex.com>

        * tests/: Rename testcase badinc3 to badinc4 and actually run it, and
          add new badinc3 which tests multiple levels of *include.  Add expect
          output for all the badinc testcases.

Mon Dec 17 11:01:02 GMT 2012  Olly Betts <olly@survex.com>

        * src/datain.c: Report the parent include files starting from the
          outermost, as that's more logical when there are multiple levels
          involved.

Mon Dec 17 10:39:14 GMT 2012  Olly Betts <olly@survex.com>

        * lib/fr.po: Add translation for new message, adapted from two similar
          existing messages.

Mon Dec 17 10:37:12 GMT 2012  Olly Betts <olly@survex.com>

        * lib/it.po: Merge a translation from launchpad.

Mon Dec 17 09:11:09 GMT 2012  Olly Betts <olly@survex.com>

        * lib/: Merge changes from .pot to .po files.

Mon Dec 17 06:37:10 GMT 2012  Olly Betts <olly@survex.com>

        * lib/,src/datain.c: Move the <filename>:<line> into the message when
          reporting the include route to the file with the error in it, which
          allows a more natural translation into German.

Mon Dec 17 03:26:40 GMT 2012  Olly Betts <olly@survex.com>

        * .gitignore: Add src/dump3d.

Mon Dec 17 03:24:22 GMT 2012  Olly Betts <olly@survex.com>

        * lib/po_codes,lib/po_codes_dead: Prune strings we aren't using and are
          probably unlikely to use again into a new file po_codes_dead, so that
          translators don't get presented with them to translate.
        * lib/survex.pot: Regenerate.

Tue Dec 11 23:07:31 GMT 2012  Olly Betts <olly@survex.com>

        * src/datain.c,tests/: We want to warn if there's a clino reading which
          it would be impossible to have read from the instrument (e.g. on a
          -90 to 90 degree scale you can't read "96" (it's probably a typo for
          "69").  However, the gradient reading from a topofil is typically in
          the range 0 to 180, with 90 being horizontal.  Really we should allow
          the valid range to be specified, but for now we infer it from the
          zero error - if this is within 45 degrees of 90 then we assume the
          range is 0 to 180.

Tue Dec 11 22:29:35 GMT 2012  Olly Betts <olly@survex.com>

        * lib/po-to-msg.pl: Report unused message numbers.

Tue Dec 11 22:22:20 GMT 2012  Olly Betts <olly@survex.com>

        * lib/po_codes,lib/survex.pot,src/commands.c,tests/: If the scale
          factor in *calibrate is zero, flag that as an error - it doesn't
          make sense and probably means someone reversed the arguments to
          *calibrate.

Mon Dec 03 06:52:22 GMT 2012  Olly Betts <olly@survex.com>

        * src/readval.c: If we were expecting a numeric field and instead get
          something which starts with '+', '-', or '.' but which isn't a
          number, then fix the error to include that character in the token
          reported.
        * tests/: Add regression test badreadingdotplus.

Mon Dec 03 06:50:51 GMT 2012  Olly Betts <olly@survex.com>

        * tests/cavern.tst,tests/equatenosuchstn.out,tests/surveytypo.out: Stop
          trimming output header when we get to copyright line, as there may be
          an error before the first blank line.

Mon Dec 03 06:34:20 GMT 2012  Olly Betts <olly@survex.com>

        * tests/badinc3.svx: Add new test file, missed in earlier commit.

Mon Dec 03 04:18:34 GMT 2012  Olly Betts <olly@survex.com>

        * src/cavern.c: Use /* */ comments, not //.

Mon Dec 03 04:16:40 GMT 2012  Olly Betts <olly@survex.com>

        * tests/Makefile.am: Add new test suite files.

Mon Dec 03 04:13:32 GMT 2012  Olly Betts <olly@survex.com>

        * src/datain.c,tests/cavern.tst: Fix handling after reporting an error
          for a bad reading in passage data to not then complain "End of line
          not blank" but instead check other readings on the same line.
        * tests/passagebad.svx: Add regression testcase.

Mon Dec 03 02:55:33 GMT 2012  Olly Betts <olly@survex.com>

        * tests/cavern.tst,tests/extend.tst,tests/smoke.tst: Add valgrind hooks
          to the rest of the tests scripts.

Mon Dec 03 02:53:56 GMT 2012  Olly Betts <olly@survex.com>

        * configure.ac: Fix package name, broken during modernisation of
          autotools use.

Mon Dec 03 02:32:01 GMT 2012  Olly Betts <olly@survex.com>

        * tests/: Run tools under valgrind in most test scripts if VALGRIND is
          set.

Mon Dec 03 02:29:56 GMT 2012  Olly Betts <olly@survex.com>

        * tests/smoke.tst: Remove variables which aren't ever used.

Mon Dec 03 02:28:45 GMT 2012  Olly Betts <olly@survex.com>

        * tests/: Make all test scripts report "Test passed" at the end if
          VERBOSE is set and all testcases in the script passed.

Mon Dec 03 01:59:04 GMT 2012  Olly Betts <olly@survex.com>

        * tests/cavern.tst: If VALGRIND is set, run cavern under valgrind and
          fail the test if there's an error.

Mon Dec 03 01:29:39 GMT 2012  Olly Betts <olly@survex.com>

        * src/datain.c: Refactor to avoid duplicating code for handling clino
          and backclino.

Mon Dec 03 01:29:05 GMT 2012  Olly Betts <olly@survex.com>

        * src/datain.c: Check r is valid before using it at all.

Sun Dec 02 23:48:05 GMT 2012  Olly Betts <olly@survex.com>

        * src/str.c,src/str.h: Inline s_zero() and s_free() since they should
          optimise down to similar or less code than a function call would.

Sun Dec 02 23:47:21 GMT 2012  Olly Betts <olly@survex.com>

        * src/datain.c: s_zero() on a NULL pointer is a no-op, so remove.

Sun Dec 02 22:53:34 GMT 2012  Olly Betts <olly@survex.com>

        * lib/de_CH.po: Consistently use Swiss quoting style.

Sun Dec 02 22:51:53 GMT 2012  Olly Betts <olly@survex.com>

        * src/readval.c: If we're about to longjmp to jbSkipLine, then we can
          just call compile_error() instead of compile_error_skip().

Sun Dec 02 22:40:07 GMT 2012  Olly Betts <olly@survex.com>

        * src/datain.c: Always skip the current line if we longjmp to
          jbSkipLine.
        * tests/cavern.tst,tests/skipafterbadomit.svx: We weren't skipping
          after complaining about OMIT for a required reading, which the
          change to always skip fixes, so add a regression test for that.

Sat Dec 01 23:42:22 GMT 2012  Olly Betts <olly@survex.com>

        * src/readval.c: Add a "const".

Fri Nov 30 00:31:16 GMT 2012  Olly Betts <olly@survex.com>

        * lib/it.po,lib/sk.po: Merge more updates from launchpad.

Wed Nov 28 01:56:49 GMT 2012  Olly Betts <olly@survex.com>

        * lib/,src/sorterr.c: Change "HOW MANY" to "HOW_MANY" to make it
          clearer this is a placeholder for one argument.

Wed Nov 28 01:52:16 GMT 2012  Olly Betts <olly@survex.com>

        * src/message.c: Don't force Latin 1 if setlocale(LC_MESSAGES, ...)
          fails.

Wed Nov 28 01:51:11 GMT 2012  Olly Betts <olly@survex.com>

        * src/message.c: Transliterate « and » to " if we don't have them in

        * lib/: Merge translations from launchpad.

Wed Nov 28 00:44:36 GMT 2012  Olly Betts <olly@survex.com>

        * lib/de_CH.po: Fill gaps from de.po.

          which have the "c-format" flag set.

Tue Nov 27 23:57:25 GMT 2012  Olly Betts <olly@survex.com>

        * lib/po-to-msg.pl: Fix quote check to handle “” vs »«.

Tue Nov 27 23:40:06 GMT 2012  Olly Betts <olly@survex.com>

        * lib/de.po,lib/po_codes,lib/survex.pot: Reorder messages so the ones
          in the "View" menu are together in order.  Adjust menu accelerators
          for the German translation to avoid clashes in the View menu.

        * lib/de.po: Merge more updates from launchpad.

        * src/guicontrol.cc,src/mainfrm.cc: On OS X, F11 is used by the desktop

Mon Oct 15 04:19:57 GMT 2012  Olly Betts <olly@survex.com>

        * Makefile.am,configure.ac: Modern automake seems to cope with files
          required by GNU being generated during the build, so we no longer
          need to use the "foreign" automake mode.  Also use -Werror with
          automake.

Mon Oct 15 02:28:46 GMT 2012  Olly Betts <olly@survex.com>

        * src/Makefile.am: Remove workaround for GCC 2.95 failing to compile

          configure.ac from passing version to AM_INIT_AUTOMAKE to passing it
          to AC_INIT, and fix places which grep out the version.

Mon Oct 15 02:08:23 GMT 2012  Olly Betts <olly@survex.com>

        * buildmacosx.sh,configure.ac,configure.in,doc/Makefile.am,
          lib/mailmsgs.pl: Rename configure.in to configure.ac to make modern
          autotools usage.

Thu Sep 27 10:41:56 GMT 2012  Olly Betts <olly@survex.com>

        * src/: Switch read_prefix_*() family of functions to be a single
          read_prefix() function which tags a bitmask of flags.

Thu Sep 27 09:23:41 GMT 2012  Olly Betts <olly@survex.com>

        * lib/id.po: Resolve clashing menu accelerators.

Thu Sep 27 05:37:18 GMT 2012  Olly Betts <olly@survex.com>

        * src/namecompare.cc: Fix to build with wx2.8.

Thu Sep 27 05:25:49 GMT 2012  Olly Betts <olly@survex.com>

        * NEWS: Update from ChangeLog.

Thu Sep 27 05:12:22 GMT 2012  Olly Betts <olly@survex.com>

        * src/message.c: For determining character set on Unix, check LANG
          after LC_ALL and LC_CTYPE.  For determining language, check LC_ALL
          before LC_MESSAGES and LANG.

Thu Sep 27 04:48:34 GMT 2012  Olly Betts <olly@survex.com>

        * lib/id.po: Add more translations and fix marking of unused messages.

          Indonesian translation from launchpad.

Thu Sep 27 03:56:22 GMT 2012  Olly Betts <olly@survex.com>

        * lib/: Merge translation updates from launchpad.

Sat Sep 22 05:06:23 GMT 2012  Olly Betts <olly@survex.com>

        * src/mainfrm.cc,src/mainfrm.h: Don't run incremental search on every
          key-press, as on a slow machine the short initial search(es) will
          take a while but not be useful.  Instead set a flag, and actually
          run the search when MainFrm next receives an idle event.

Fri Sep 21 06:24:32 GMT 2012  Olly Betts <olly@survex.com>

        * src/img.h: New leg flag img_FLAG_NOSURVEY.

Fri Sep 07 11:39:06 GMT 2012  Olly Betts <olly@survex.com>

        * src/namecompare.cc,src/namecompare.h: Add two new files which were
          in the last release but I failed to commit.

Tue Aug 14 09:42:43 GMT 2012  Olly Betts <olly@survex.com>

        * lib/Makefile.am: Create de_DE.po as a symlink if it doesn't exist.

Mon May 28 16:56:27 GMT 2012  Olly Betts <olly@survex.com>

        * src/: Remove unused parameter names.

Sun May 27 12:24:17 GMT 2012  Olly Betts <olly@survex.com>

Fri May 25 14:20:24 GMT 2012  Olly Betts <olly@survex.com>

        * tests/cavern.tst,test/equatenosuchstn.out: Drop line reporting time
          taken when comparing output, as that can vary.
        * src/listpos.c,tests/equatenosuchstn.out: Move "Station X referred to
          just once" warning after non-existent survey check.
        * src/,tests/: If survey isn't all connected, still run survey tree
          checks and report errors and/or warnings which might suggest typo
          locations.

Tue Feb 28 00:41:15 GMT 2012  Olly Betts <olly@survex.com>

        * tests/diffpos.tst: Force English messages for diffpos tests too.

Tue Feb 28 00:39:45 GMT 2012  Olly Betts <olly@survex.com>

        * tests/cavern.tst: Force English messages so comparing expected output
          works whatever the current language setting.

Fri Feb 24 00:43:04 GMT 2012  Olly Betts <olly@survex.com>

        * tests/cavern.tst,tests/equatenosuchstn.out: Fix test failure due to
          Survex version number appearing in expected output.

Thu Feb 23 22:34:52 GMT 2012  Olly Betts <olly@survex.com>

        * make_release: Link mingw build statically to avoid needing libgcc

        * lib/po_codes,lib/survex.pot,src/listpos.c,tests/: If we have a
          reference to a station in a non-existent survey, give a helpful error
          rather than saying the station hasn't been exported from the survey.

Tue Jan 24 23:03:10 GMT 2012  Olly Betts <olly@survex.com>

        * src/cavern.c: Remove TRANSLATE comment which has already been

Tue Jan 24 04:38:11 GMT 2012  Olly Betts <olly@survex.com>

Tue Jan 24 04:35:25 GMT 2012  Olly Betts <olly@survex.com>

        * src/cmdline.c: Allow help argument to cmdline_init() to be NULL.

Tue Jan 24 04:19:29 GMT 2012  Olly Betts <olly@survex.com>

        * src/findentrances.cc: Other survex tools use -s for "limit operation
          to this survey prefix" and just take the .3d file to operate on as
          a command line argument, so for consistency just take the .3d file
          as a command line argument here too.

Tue Jan 24 04:18:41 GMT 2012  Olly Betts <olly@survex.com>

        * src/findentrances.cc: Reindent with 4 space indent, tab width 8.

Fri Jan 06 11:34:16 GMT 2012  Olly Betts <olly@survex.com>

        * lib/,src/Makefile.am,src/gettexttomsg.pl: Rename codes.po to po_codes
          so it doesn't get picked up by tools looking for .po files.  Add
          survex.pot to the repo so launchpad's auto translation syncing can
          work.

Fri Jan 06 11:25:23 GMT 2012  Olly Betts <olly@survex.com>

        * lib/Makefile.am: Make the containing directory in the launchpad

        * lib/fr.po: Incorporate a translation from launchpad I'd previously
          copied the English version of by mistake.  Attempt to correct

Tue Jan 03 13:21:09 GMT 2012  Olly Betts <olly@survex.com>

        * make_release: Need to set VERSION before we first use it!

          underneath them.

Mon Jan 02 12:52:47 GMT 2012  Olly Betts <olly@survex.com>

        * src/message.c: Improve handling of messages before the message
          subsystem is fully initialised.

Mon Jan 02 12:37:18 GMT 2012  Olly Betts <olly@survex.com>

        * src/Makefile.am,src/mainfrm.cc,src/namecmp.h: Add a version of the
          station name comparing algorithm which works with the Unicode strings
          directly, which fixes the issue with random ordering of the prefix
          tree control in aven due to the converted strings we were comparing 
          getting invalidated before we actually compared them.

Mon Jan 02 12:12:35 GMT 2012  Olly Betts <olly@survex.com>

        * src/gla-gl.cc: If glGenLists() fails, flag the list as NEVER_CACHE
          as there's unlikely to be much point calling glGenLists() again.
        * src/gla-gl.cc,src/gla.h: Replace GLAList methods test_flag() and
          InvalidateList() with an invalidate_if() method.

Mon Jan 02 11:54:38 GMT 2012  Olly Betts <olly@survex.com>

        * src/gfxcore.cc,src/gla-gl.cc: No need to invalidate the display lists
          for the compass and clino when a new survey is loaded as they don't
          depend on the survey data.

Mon Jan 02 11:17:51 GMT 2012  Olly Betts <olly@survex.com>

        * src/gla-gl.cc,src/gla.h: Rework list caching code to not call
          glDeleteLists() and glGenLists() when a list is invalidated, as that
          results in a fresh list number being allocated (at least with the
          OpenGL implementation I'm using) which would eventually result in
          aven hitting an assertion which is there to catch if we leak lists.

Sun Jan 01 13:29:03 GMT 2012  Olly Betts <olly@survex.com>

        * lib/Makefile.am: Put translation files in a sub-directory in the

          SHA1 checksums for the uploaded files.

Sun Jan 01 02:56:04 GMT 2012  Olly Betts <olly@survex.com>

        * NEWS,configure.in: Update for 1.2.4.

Sun Jan 01 02:32:59 GMT 2012  Olly Betts <olly@survex.com>

        * src/gfxcore.cc,src/gfxcore.h: Improve labelling of depth colour key
          to avoid sub-picometre precision on near-zero values (ticket#30).
          We now always use metres or feet for the depth with a consistent
          precision chosen from the depth range, and show the units below
          the colour bar rather than after every value.
        * src/gfxcore.cc,src/gfxcore.h: When zooming way in, stay in metres
          rather than switching to cm.  Say “1 mile” rather than “1 miles”.

Sat Dec 31 22:40:07 GMT 2011  Olly Betts <olly@survex.com>

        * src/gla-gl.cc: Fix not to make OpenGL calls before we've initialised
          OpenGL, as this can cause segmentation faults (e.g. on Fedora 16).
          Extend CHECK_GL_ERROR() to check that we don't make such calls in
          future.

Sat Dec 31 22:37:47 GMT 2011  Olly Betts <olly@survex.com>

        * lib/es.po: Fix "Last-Translator:" header and merge in translation
          of a message which is not currently used.

Sat Dec 31 12:43:52 GMT 2011  Olly Betts <olly@survex.com>

        * lib/Makefile.am: Add launchpad-tarball target to make a tarball
          of the translations suitable for uploading to launchpad.

Sat Dec 31 12:23:39 GMT 2011  Olly Betts <olly@survex.com>

        * make_release: Echo the commands to copy the new release to the web
          server at the end.
        * copy-prerelease,copy-release: Remove old scripts which are no longer
          useful.

        * src/img.h: Fix incorrect comment which claimed that img_XFLAG_END
          was no longer used.
        * src/img.c: Use img_XFLAG_END constant rather than assuming it is

        * src/extend.c: Copy the end markers for passage tubes, and preserve
          left and right data for tubes (previously they were set to -1.0
          which means "no info").

Sat Dec 31 08:17:08 GMT 2011  Olly Betts <olly@survex.com>

        * lib/extract-msgs.pl: New script to allow developers to update
          codes.po from source code.
        * lib/Makefile.am: Ship it.
        * src/Makefile.am: Add rule to run it on all used sources and generate
          newcodes.po which can then be compared with current version.

        * lib/,src/: Use curly apostrophe instead of "'" in messages.  Correct

Tue Nov 01 18:54:32 GMT 2011  Olly Betts <olly@survex.com>

        * lib/sk.po: Update a translation from launchpad.

Tue Nov 01 18:32:24 GMT 2011  Olly Betts <olly@survex.com>

        * src/log.cc,src/log.h: Fix to build with wx 2.9.2.

Tue Nov 01 18:15:20 GMT 2011  Olly Betts <olly@survex.com>

        * src/export.cc: Fix to build with wx 2.9.2.

Tue Nov 01 18:14:13 GMT 2011  Olly Betts <olly@survex.com>

        * src/aboutdlg.cc: Fix code conditionally used on 2.9.2 and later to
          actually compile.

Tue Nov 01 18:12:42 GMT 2011  Olly Betts <olly@survex.com>

        * src/gfxcore.cc: Fix how we pass on events from right-click menus of
          indicators.  The previous code seemed to work, but wasn't correct
          as highlighted by trying to build it with 2.9.2 which now refuses
          to build to avoid people getting this wrong.

Tue Nov 01 18:11:55 GMT 2011  Olly Betts <olly@survex.com>

        * src/aven.h: Need to forward declare class wxPageSetupDialogData for
          wx 2.9.2.

Tue Nov 01 18:11:22 GMT 2011  Olly Betts <olly@survex.com>

        * src/glbitmapfont.h: Fix to build with wx 2.9.2.

Tue Nov 01 18:10:51 GMT 2011  Olly Betts <olly@survex.com>

        * src/cavernlog.cc: Fix to build with wx 2.9.2.

Tue Nov 01 18:06:12 GMT 2011  Olly Betts <olly@survex.com>

        * lib/INSTALL.OSX,src/mainfrm.cc: Make the green colour used for
          entrances in the survey tree the same (slightly darker than
          before) green used for the entrance blobs.

Tue Nov 01 18:04:47 GMT 2011  Olly Betts <olly@survex.com>

        * src/gla-gl.cc: Fix warning when building with wx2.9.2.

Tue Nov 01 12:32:30 GMT 2011  Olly Betts <olly@survex.com>

        * src/printwx.cc: Fix Y coordinates of surface surveys on printouts.
          (Closes #32)

Sun Oct 23 06:20:14 GMT 2011  Olly Betts <olly@survex.com>

        * lib/Info.plist.in: Remove spurious blank lines from licence text
          in OS X "Get Info".

Sat Oct 22 17:39:07 GMT 2011  Olly Betts <olly@survex.com>

        * doc/TODO.htm: Opening dialogs while in full screen mode now works
          better in wxGTK.

Sat Oct 22 17:36:01 GMT 2011  Olly Betts <olly@survex.com>

        * lib/INSTALL.OSX: Processing .svx files from aven now works.

Sat Oct 22 07:27:43 GMT 2011  Olly Betts <olly@survex.com>

        * src/printwx.h: Update comment - Mac OS X does indeed provide its own
          preview menu.

Fri Oct 21 23:47:16 GMT 2011  Olly Betts <olly@survex.com>

        * src/cavernlog.cc: Fix openiof .svx file when user clicks on cavern
          warning or error.

Fri Oct 21 23:43:21 GMT 2011  Olly Betts <olly@survex.com>

        * buildmacosx.sh: Include a hardlinked cavern alongside aven in
          the app so that processing .svx files in aven works.

Wed Oct 19 22:51:18 GMT 2011  Olly Betts <olly@survex.com>

        * tests/diving.pos,tests/diving.svx: Add test coverage for interleaved
          diving data.

Wed Oct 19 13:04:25 GMT 2011  Olly Betts <olly@survex.com>

        * tests/diving.pos,tests/diving.svx: Add testcase for diving data
          with topofil-style distance.

Wed Oct 12 03:45:13 GMT 2011  Olly Betts <olly@survex.com>

        * src/aboutdlg.cc: Report the version of the library we're actually
          running with if built against wx >= 2.9.2.  Make it clear that the
          the version reported is the version built with for wx < 2.9.2.

Wed Oct 12 03:06:05 GMT 2011  Olly Betts <olly@survex.com>

        * lib/make-pixel-font,src/glbitmapfont.cc,src/glbitmapfont.h: Space the
          glyphs to leave a one pixel gap either side of each one (so two
          between adjacent glyphs).  Mostly this reduces the horizontal width,
          but it adds a pixel for characters like "m" and two in a few cases.

Fri Oct 07 07:20:55 GMT 2011  Olly Betts <olly@survex.com>

        * src/glbitmapfont.cc,src/glbitmapfont.h: Support plotting Unicode
          character points > 256 on the survey pane by lazily loading the
          data for them from the font file and plotting them with a direct
          call to glBitmap() rather than using a display list.

Fri Oct 07 04:09:58 GMT 2011  Olly Betts <olly@survex.com>

        * lib/make-pixel-font: Fix .pixelfont file to correctly handle
          characters wider than 8 pixels when run on a little-endian platform.

Thu Oct 06 13:23:05 GMT 2011  Olly Betts <olly@survex.com>

        * NEWS: Another update for 1.2.2.

Thu Oct 06 13:21:20 GMT 2011  Olly Betts <olly@survex.com>

        * src/gfxcore.cc: Fix grid not to disappear when blobs are turned on
          if blobs are drawn using lines.

Thu Oct 06 13:17:19 GMT 2011  Olly Betts <olly@survex.com>

        * NEWS,configure.in: Update for 1.2.2.

Thu Oct 06 12:11:20 GMT 2011  Olly Betts <olly@survex.com>

        * src/printwx.cc: Fix to calculate the scale required for "One page"
          right before we calculate how many pages are required, so we don't
          end up something other than 1x1 being shown when the user changes
          settings.

Thu Oct 06 12:07:10 GMT 2011  Olly Betts <olly@survex.com>

        * src/avenprcore.cc: The info box is now always 30mm high (if present)
          so update the code which picks a scale and which decides how many
          pages are required to use this height.

Thu Oct 06 11:34:51 GMT 2011  Olly Betts <olly@survex.com>

        * src/printwx.h: SomethingChanged() method doesn't need to be public,
          so make it private.

Thu Oct 06 04:13:24 GMT 2011  Olly Betts <olly@survex.com>

        * src/gettexttomsg.pl: Update for the message.txt -> codes.po change.

Thu Oct 06 03:01:45 GMT 2011  Olly Betts <olly@survex.com>

        * src/gfxcore.cc: Passage tubes can stick out above the highest survey
          station or below the lowest, so clamp the value used to calculate
          the colour in these cases, like we already do elsewhere.

Thu Oct 06 02:52:13 GMT 2011  Olly Betts <olly@survex.com>

        * src/gfxcore.cc: Avoid a different assertion failure due to rounding
          differences.

Thu Oct 06 02:49:03 GMT 2011  Olly Betts <olly@survex.com>

        * src/glbitmapfont.cc,src/glbitmapfont.h: Actually add the new
          glBitmap-based font code.

Thu Oct 06 02:36:47 GMT 2011  Olly Betts <olly@survex.com>

        * survex.iss.in: Update for font changes.

Thu Oct 06 02:35:41 GMT 2011  Olly Betts <olly@survex.com>

        * Makefile.am,buildmacosx.sh,lib/Makefile.am,lib/afm2txf.pl,
          lib/make-pixel-font,src/: Replace the textured-mapped font drawing
          with an approach based on glBitmap.  This doesn't suffer from the
          character alignment issues which the textured-mapped fonts had,
          and is actually significantly faster on some machines.  The current
          font used is (mostly) fixed-width, but this isn't an inherent
          limitation - it was just the easiest font data to convert to a
          usable format.

Wed Oct 05 13:49:15 GMT 2011  Olly Betts <olly@survex.com>

        * src/gfxcore.cc: Avoid assertion failure due to rounding differences.

Wed Oct 05 08:19:46 GMT 2011  Olly Betts <olly@survex.com>

        * src/printwx.cc: Fix not to pass wxString through varargs (issue
          introduced in the previous commit).

Tue Oct 04 04:49:19 GMT 2011  Olly Betts <olly@survex.com>

        * src/printwx.cc: Use degree sign from message file rather than a
          literal one.

Tue Oct 04 04:08:57 GMT 2011  Olly Betts <olly@survex.com>

        * src/message.c: If degree sign isn't available, transliterate it to
          'dg' rather than skipping it.

Tue Oct 04 03:59:29 GMT 2011  Olly Betts <olly@survex.com>

        * lib/codes.po,src/gfxcore.cc,src/mainfrm.cc: Fix message code 344
          which should have been a degree sign but got lost in the format
          change for 1.2.0 and then got reassigned in 1.2.1.  Externally, this
          means that bearing in the status bar now have a degree sign after
          them if they are in degrees rather than nothing (1.2.0) or "&Hide
          Compass" (1.2.1).

Tue Oct 04 02:55:11 GMT 2011  Olly Betts <olly@survex.com>

        * NEWS,configure.in: Update for 1.2.1.

Tue Oct 04 02:45:47 GMT 2011  Olly Betts <olly@survex.com>

        * src/Makefile.am: Don't ship the removed hand_mask.xpm.

Tue Oct 04 02:44:37 GMT 2011  Olly Betts <olly@survex.com>

        * src/gfxcore.cc: Sort out inverted cursor mask on __WXMSW__.
        * src/hand.xbm: Invert the dragging hand cursor black vs white so it
          better matches the other cursors.

Mon Oct 03 23:42:00 GMT 2011  Olly Betts <olly@survex.com>

        * src/printwx.cc: Add back svxPrintout methods GetPageInfo() and
          HasPage() which are actually virtual methods called by the parent
          class.

Mon Oct 03 02:40:56 GMT 2011  Olly Betts <olly@survex.com>

        * lib/Makefile.am: Fix check of .po files not to create messages.mo.

Mon Oct 03 02:22:55 GMT 2011  Olly Betts <olly@survex.com>

        * lib/Makefile.am: Fix new translation checking rules to work in a
          VPATH build.

Mon Oct 03 02:12:23 GMT 2011  Olly Betts <olly@survex.com>

        * lib/de.po,lib/de_CH.po,lib/sk.po: Fix classes menu accelerators.

Mon Oct 03 02:00:38 GMT 2011  Olly Betts <olly@survex.com>

        * lib/en_US.po: Fix problem with translation of new message.

Mon Oct 03 00:50:52 GMT 2011  Olly Betts <olly@survex.com>

        * NEWS: Update from ChangeLog.

Sun Oct 02 20:25:01 GMT 2011  Olly Betts <olly@survex.com>

        * lib/,src/printwx.cc: Add mnemonics to the "Plan" and "Elevation"
          buttons in the print dialog.

Sun Oct 02 12:17:34 GMT 2011  Olly Betts <olly@survex.com>

        * src/guicontrol.cc: Try processing F11 explicitly for __WXMAC__ to
          avoiding getting stuck in full screen mode forever.

Sun Oct 02 12:01:25 GMT 2011  Olly Betts <olly@survex.com>

        * src/: Make the sign of the tilt angle for printouts consistent with
          the sign in the UI.

Sun Oct 02 10:00:08 GMT 2011  Olly Betts <olly@survex.com>

        * lib/codes.po,lib/en_US.po,src/printwx.cc: On printouts, combine the
          "Plan View"/"Elevation" info box field with the field which gives
          the bearing and reduce the height on the info box by the removed
          field, so it's now 3cm for plans and elevations, as for extended
          elevations.  Report the tilt angle for tilted elevations which it
          seems has been missing for ages (it's not in recent 1.0.x either).

Sat Oct 01 12:28:35 GMT 2011  Olly Betts <olly@survex.com>

        * src/printwx.cc: Fix commented message in source.

Sat Oct 01 12:11:37 GMT 2011  Olly Betts <olly@survex.com>

        * src/printwx.h: svxPrintDlg members don't need to be protected, so
          make the private.

Sat Oct 01 11:28:34 GMT 2011  Olly Betts <olly@survex.com>

        * src/printwx.cc,src/printwx.h: When in plan view disable the "Plan"
          button, and similarly for the "Elevation" button.

Sat Oct 01 11:20:03 GMT 2011  Olly Betts <olly@survex.com>

        * src/printwx.cc: Remove more unused methods and members.

Sat Oct 01 10:48:24 GMT 2011  Olly Betts <olly@survex.com>

        * src/avenprcore.cc,src/printwx.cc,src/printwx.h: Eliminate some unused
          methods and member variables.

Sat Oct 01 00:33:24 GMT 2011  Olly Betts <olly@survex.com>

        * src/printwx.cc: Move the footer to start at the left side of the
          page.

Fri Sep 30 23:49:24 GMT 2011  Olly Betts <olly@survex.com>

        * src/printwx.cc:svxPrintout::ShowPage() is an empty method, so just
          remove it and all the code to calculate values to pass to it and
          then call it.  This is just a left-over from the 1.0 printing code.

Fri Sep 30 13:40:29 GMT 2011  Olly Betts <olly@survex.com>

        * src/aven.cc,src/gfxcore.cc,src/mainfrm.cc: Use standard C++ true and
          false instead of wx aliases TRUE and FALSE (which even wx seems to
          have shifted away from using now).

Fri Sep 30 13:33:37 GMT 2011  Olly Betts <olly@survex.com>

        * src/printwx.cc: Tweak exact positioning of text to look nicer.

Fri Sep 30 03:49:16 GMT 2011  Olly Betts <olly@survex.com>

        * INSTALL: Mention building wxWidgets with --enable-unicode.  Mention
          using sudo for the install.  Capitalise Survex when talking about
          the package.
        + doc/manual.sgml: Replace building from source instructions with a
          pointer to the clearer instructions in INSTALL.  Make it clear that
          installing with administrator rights applies to NT, 2000, XP *or
          newer*.

Fri Sep 30 03:31:00 GMT 2011  Olly Betts <olly@survex.com>

        * src/guicontrol.cc: Don't disable a colour by option unless there's
          no survey loaded.  It feels inconsistent now we are showing a key
          even when there's no "interesting" data.

Fri Sep 30 03:28:59 GMT 2011  Olly Betts <olly@survex.com>

        * src/gfxcore.cc,src/gfxcore.h: The different colour keys get cached
          so switching back to one that's already been shown for the current
          survey doesn't redraw it and key_lowerleft wasn't getting updated.
          We now track key_lowerleft for each key type separately.

Fri Sep 30 02:48:00 GMT 2011  Olly Betts <olly@survex.com>

        * src/gfxcore.cc: If "Colour by X" is selected, always show the colour
          key, even if it only contains one colour, or just the entry for
          white.

Thu Sep 29 22:33:06 GMT 2011  Olly Betts <olly@survex.com>

        * src/gfxcore.cc: Don't segfault on a flat survey.  Fix incorrect
          addition and corresponding subtraction of GetDepthExtent() when
          calculating splits over depth band boundaries.

Thu Sep 29 21:56:19 GMT 2011  Olly Betts <olly@survex.com>

        * src/gfxcore.cc,src/gla.h: Fix zoom in limit to be the same distance
          regardless of the extent of the survey.

Thu Sep 29 20:57:41 GMT 2011  Olly Betts <olly@survex.com>

        * src/gfxcore.cc: Now that we don't have the key background, just
          remove KEY_MARGIN entirely.

Thu Sep 29 20:37:09 GMT 2011  Olly Betts <olly@survex.com>

        * src/gfxcore.cc: Remove the dark grey background from the colour key
          and just put a single pixel black border around the colours.  This
          is more in keeping with the other controls, and means the colours
          are now on a black background so more visually similar to the survey
          legs.

Thu Sep 29 13:02:22 GMT 2011  Olly Betts <olly@survex.com>

        * src/mainfrm.cc: Fall back to ISO8859-1 if CP1252 fails to convert the
          string.

Thu Sep 29 12:22:34 GMT 2011  Olly Betts <olly@survex.com>

        * src/gfxcore.cc: Upon loading a survey which lacks the information for
          the current "Colour by" mode, don't change to "Colour by none" - we
          already do no colouring and hide the key when there's nothing to
          colour by, and it's annoying to have the actual mode changed if you
          then load a survey which does have the information to colour by.

Thu Sep 29 12:20:07 GMT 2011  Olly Betts <olly@survex.com>

        * src/gfxcore.cc: Rename COLOUR_KEY_* constants to KEY_*.

Thu Sep 29 10:16:30 GMT 2011  Olly Betts <olly@survex.com>

        * src/gfxcore.cc: Make COLOUR_KEY_OFFSET_X and COLOUR_KEY_OFFSET_Y the
          actual offsets, rather than taking COLOUR_KEY_MARGIN off them.

Thu Sep 29 05:08:20 GMT 2011  Olly Betts <olly@survex.com>

        * src/mainfrm.cc: Fix tooltip for open to say "survey file" not "3D
          file".

Thu Sep 29 05:03:37 GMT 2011  Olly Betts <olly@survex.com>

        * src/gfxcore.cc,src/gfxcore.h,src/mainfrm.cc: Add right click menu to
          the colour key too.

Wed Sep 28 14:47:15 GMT 2011  Olly Betts <olly@survex.com>

        * lib/afm2txf.pl: Add a kludge to prefer to round values up when
          generating the .txf file which empirically results in better
          horizontal spacing (this should be fixed properly, but this is
          at least an easy improvement for now).

Wed Sep 28 14:00:14 GMT 2011  Olly Betts <olly@survex.com>

        * lib/afm2txf.pl: Rather than special-casing the character with
          PostScript name 'space', just omit characters with zero width and
          height from the texture.

Wed Sep 28 12:41:42 GMT 2011  Olly Betts <olly@survex.com>

        * lib/afm2txf.pl: Put the digits first in the font texture to help
          ensure they are all on the same line and will exactly align
          vertically when rendered - a slight discrepancy here is particularly
          visible in the colour key legends and compass bearing.

Wed Sep 28 12:30:03 GMT 2011  Olly Betts <olly@survex.com>

        * lib/Makefile.am: Regenerate aven.txf if the script which generates it
          has been modified.

Wed Sep 28 11:15:08 GMT 2011  Olly Betts <olly@survex.com>

        * lib/afm2txf.pl: Fix handling of PostScript character names which are
          used by more than one Unicode value ("space" and "hyphen" are the
          current examples).  This fixes the colour key for date to have dashes
          in the dates.  Fix not to bother writing empty space into the texture
          map for spaces - just set width and height to 0 and skip to the
          width.
        * src/fnt.cc: Remove special case kludge for if space isn't defined,
          which is no longer needed thanks to the above fix.

Wed Sep 28 10:19:07 GMT 2011  Olly Betts <olly@survex.com>

        * lib/,src/printwx.cc: Fix mixed up messages - the print dialog now
          says "View" on the left subgroup of controls. Improve the display of
          the bearing on printouts.  Add message for "Colour &Key" to
          translations.

Wed Sep 28 02:02:09 GMT 2011  Olly Betts <olly@survex.com>

        * src/aven.cc: Fix #ifdef to #if in previous change.

Wed Sep 28 01:09:09 GMT 2011  Olly Betts <olly@survex.com>

        * src/aven.cc: Fix for non-Unicode build.

Mon Sep 26 12:25:59 GMT 2011  Olly Betts <olly@survex.com>

        * src/export.cc: PLT file output now handles spaces and control
          characters in station names by escaping them with '%' as in URLs.

Mon Sep 26 11:58:05 GMT 2011  Olly Betts <olly@survex.com>

        * src/aventreectrl.cc: Improve comment about WXK_PRIOR and WXK_NEXT.

Mon Sep 26 11:51:01 GMT 2011  Olly Betts <olly@survex.com>

        * src/aventreectrl.cc: Pressing "Enter" on a station in the tree
          control now centres the view on that station.

Mon Sep 26 11:42:17 GMT 2011  Olly Betts <olly@survex.com>

        * src/gfxcore.h,src/guicontrol.cc: Pressing "F5" forces all GLAList
          objects to be invalidated and then forces a refresh of the display.
          This is intended as a debugging aid - if pressing F5 changes the
          display at all then there's a missing case where a list should
          have been invalidated.

Mon Sep 26 11:35:29 GMT 2011  Olly Betts <olly@survex.com>

        * src/: Push survey pane size tracking down into GLACanvas, and
          automatically track which lists should be invalidated on a
          changes in the width or the height of the pane.

Mon Sep 26 10:44:22 GMT 2011  Olly Betts <olly@survex.com>

        * src/gla-gl.cc,src/gla.h: Move GLAList flags out of the header as they
          are internal details.

Mon Sep 26 10:42:50 GMT 2011  Olly Betts <olly@survex.com>

        * src/gfxcore.cc,src/gfxcore.h: Cache the scale bar in a GLAList since
          it often gets redrawn exactly the same - for example, when rotating,
          panning, etc.

Mon Sep 26 09:40:32 GMT 2011  Olly Betts <olly@survex.com>

        * src/gfxcore.cc,src/gfxcore.h: More "colour key" related internal
          nomenclature changes.

Mon Sep 26 09:34:01 GMT 2011  Olly Betts <olly@survex.com>

        * src/gfxcore.cc,src/gfxcore.h: Factor out the code to draw the colour
          key into DrawColourKey().

Mon Sep 26 04:23:10 GMT 2011  Olly Betts <olly@survex.com>

        * src/gfxcore.cc: Apply COLOUR_KEY_OFFSET_Y by moving the point where
          we plot the key rather than including it in the calculations of the
          key's coordinates.

Mon Sep 26 04:17:16 GMT 2011  Olly Betts <olly@survex.com>

        * src/gfxcore.cc: Apply COLOUR_KEY_OFFSET_X by moving the point where
          we plot the key rather than including it in the calculations of the
          key's coordinates.

Sat Sep 24 13:15:22 GMT 2011  Olly Betts <olly@survex.com>

        * src/gfxcore.cc: Increase scale bar maximum width from 65% of the
          window width to 75% as it was in 1.0.x, but if that would overlap
          the clino then reduce it down until it reaches 50%.  Allow zooming
          in a little further to match what was possible in 1.0.x.  (ticket#23)

Sat Sep 24 12:45:04 GMT 2011  Olly Betts <olly@survex.com>

        * doc/TODO.htm: Update (--help messages can now be translated).

Sat Sep 24 12:21:45 GMT 2011  Olly Betts <olly@survex.com>

        * doc/TODO.htm: Note oddity with FullScreen and side panel.

Sat Sep 24 12:14:52 GMT 2011  Olly Betts <olly@survex.com>

        * src/mainfrm.h: We don't need the "un-fullscreen to show dialog" hack
          with recent wxGTK.  Also, there's no reason to think we need it for
          other platforms (it was enabled everywhere except Microsoft Windows
          before).

Sat Sep 24 10:42:29 GMT 2011  Olly Betts <olly@survex.com>

        * src/printwx.cc: "delete foo;" not "delete(foo);"

Sat Sep 24 10:41:00 GMT 2011  Olly Betts <olly@survex.com>

        * src/aven.cc,src/gfxcore.cc: No point checking for NULL before calling
          delete.

Sat Sep 24 10:18:22 GMT 2011  Olly Betts <olly@survex.com>

        * src/: Remove empty destructors.

Sat Sep 24 06:43:33 GMT 2011  Olly Betts <olly@survex.com>

        * doc/TODO.htm,src/gfxcore.cc,src/gla-gl.cc,src/gla.h: Eliminate the
          last few OpenGL calls from gfxcore.cc.

Sat Sep 24 06:32:02 GMT 2011  Olly Betts <olly@survex.com>

        * src/gfxcore.cc,src/gla-gl.cc,src/gla.h: New type GLATexCoord to avoid
          using GLint outside of the OpenGL-specific code.

Sat Sep 24 06:08:13 GMT 2011  Olly Betts <olly@survex.com>

        * src/: Move glTexCoord2i() calls out of gfxcore.cc and into gla-gl.cc.
          Use BeginQuadrilaterals() rather than BeginPolygon() when the shape
          will definitely have 4 sides.
          
Sat Sep 24 02:09:48 GMT 2011  Olly Betts <olly@survex.com>

        * src/gfxcore.h,src/guicontrol.cc: Disable "View North" when we're
          already viewing North, and similarly for other compass points.

Sat Sep 24 01:57:06 GMT 2011  Olly Betts <olly@survex.com>

        * doc/TODO.htm: Update.

Fri Sep 23 15:38:36 GMT 2011  Olly Betts <olly@survex.com>

        * doc/aven.sgml,lib/codes.po,src/: Rename the "depth bar" to "colour
          key", which better describes it now that it might show dates or
          errors.

Fri Sep 23 15:19:33 GMT 2011  Olly Betts <olly@survex.com>

        * src/gfxcore.cc,src/gfxcore.h,src/guicontrol.cc: Fix the conditions
          under which colour by date can be enabled to fully match what we
          now intend.

Fri Sep 23 15:04:35 GMT 2011  Olly Betts <olly@survex.com>

        * src/gfxcore.cc,src/mainfrm.cc: Enable "colour by date" if there are
          any surveys with date information.  Move the "Undated" / "Not in
          loop" entry down a little to improve the appearance.  Make each
          entry in the colour keys a pixel taller so it's an even number of
          pixels and will divide by two exactly.

Fri Sep 23 14:59:33 GMT 2011  Olly Betts <olly@survex.com>

        * src/fnt.cc: Remove "*1.25" fudge factor from font size for texture
          mapped fonts.

Fri Sep 23 12:44:18 GMT 2011  Olly Betts <olly@survex.com>

        * lib/en_US.po: Update for new messages.

Fri Sep 23 12:41:16 GMT 2011  Olly Betts <olly@survex.com>

        * src/gfxcore.cc: Expand context menu for compass to include "View
          North", etc;  Similarly add "Plan" and "Elevation" to clino context
          menu.

Fri Sep 23 12:25:10 GMT 2011  Olly Betts <olly@survex.com>

        * src/gla-gl.cc: Use += to make code clearer.

Fri Sep 23 12:16:36 GMT 2011  Olly Betts <olly@survex.com>

        * lib/codes.po,src/gfxcore.cc,src/gfxcore.h,src/guicontrol.cc: Add
          pop-up menus for right clicks on scale bar, compass, and clino.

Fri Sep 23 11:17:31 GMT 2011  Olly Betts <olly@survex.com>

        * src/gfxcore.cc: Use HasRangeOfDates() consistently.

Thu Sep 22 23:56:06 GMT 2011  Olly Betts <olly@survex.com>

        * src/gla-gl.cc: Add missing newline to OpenGL info when GLX info isn't
          reported.

Thu Sep 22 13:51:55 GMT 2011  Olly Betts <olly@survex.com>

        * survex.spec.in: Man pages are no longer installed in /usr/man so
          no need to move them from there.  Package aven.svg.  Package
          files for vim support.  (Fixes from James Begley)

Thu Sep 22 12:45:58 GMT 2011  Olly Betts <olly@survex.com>

        * lib/: Updates from launchpad.

Thu Sep 22 07:12:22 GMT 2011  Olly Betts <olly@survex.com>

Wed Sep 21 13:47:36 GMT 2011  Olly Betts <olly@survex.com>

        * lib/codes.po,src/cad3d.c: Tweak wording of a message.  Remove
          "unused" messages which have actually just been adapted slightly,
          add back a removed unused message, and mark an unused message as
          unused.
`
Wed Sep 21 13:20:58 GMT 2011  Olly Betts <olly@survex.com>

        * lib/codes.po,src/mainfrm.cc: Make more messages translatable.

Wed Sep 21 12:53:02 GMT 2011  Olly Betts <olly@survex.com>

        * lib/codes.po,src/: cmdline_set_syntax_message() now takes message
          numbers, plus an optional string argument.

Wed Sep 21 12:17:19 GMT 2011  Olly Betts <olly@survex.com>

        * src/mainfrm.cc: Fix to set the correct filename on the root of the
          survey tree.

Wed Sep 21 11:25:53 GMT 2011  Olly Betts <olly@survex.com>

        * lib/codes.po,src/log.cc,src/mainfrm.cc,src/printwx.cc: Make more
          messages translatable.

Wed Sep 21 07:30:28 GMT 2011  Olly Betts <olly@survex.com>

        * lib/codes.po,src/dump3d.c,src/gfxcore.cc,src/mainfrm.cc: Make more
          messages translatable.  In the colour key for "colour by date",
          change "No info" to "Undated".

Wed Sep 21 04:20:52 GMT 2011  Olly Betts <olly@survex.com>

        * lib/codes.po,src/cavernlog.cc: Allow the "Reprocess" button label in
          aven's cavern log window to be translated.

Wed Sep 21 04:07:29 GMT 2011  Olly Betts <olly@survex.com>

        * lib/,src/: Extract all the help strings in --help output and make
          them available for translation.

Wed Sep 21 04:04:31 GMT 2011  Olly Betts <olly@survex.com>

        * lib/Makefile.am: Check there are no duplicate message codes in

        * doc/manual.sgml: Tweak text about Debian packages.

Tue Sep 20 11:31:03 GMT 2011  Olly Betts <olly@survex.com>

        * tests/: Update FSF address.

Tue Sep 20 06:43:56 GMT 2011  Olly Betts <olly@survex.com>

        * src/img.c: Only define INT32_T if it isn't already defined (it will
          be for 1.0.x).

Tue Sep 20 06:43:23 GMT 2011  Olly Betts <olly@survex.com>

        * src/cavern.c: Remove unused function left over from recent change to
          how coordinate ranges get reported.

Tue Sep 20 06:42:31 GMT 2011  Olly Betts <olly@survex.com>

        * make_release: Use the URL field from svn info in the command we give
          to take this release rather than hard-coding the URL for trunk.

Tue Sep 20 05:43:11 GMT 2011  Olly Betts <olly@survex.com>

        * buildmacosx.sh: Building on 10.6 should work on 10.7, so update
          comment to more clearly reflect that.

Tue Sep 20 05:39:50 GMT 2011  Olly Betts <olly@survex.com>

        * lib/,src/cavern.c: Fix reporting of ranges of survey coordinates,
          which was broken by the message handling changes in 1.2.0.

Tue Sep 20 04:30:14 GMT 2011  Olly Betts <olly@survex.com>

        * configure.in,src/moviemaker.cc: Fix to build with FFmpeg library
          versions in Debian unstable, as well as those in Debian stable.

Tue Sep 20 03:51:40 GMT 2011  Olly Betts <olly@survex.com>

        * src/moviemaker.cc: Updates towards compatibility with newer FFmpeg
          libraries without breaking build with those in Debian stable.

Tue Sep 20 03:41:58 GMT 2011  Olly Betts <olly@survex.com>

        * src/avenprcore.h: Declare border as "struct border" rather than as a
          typedef to avoid a -Wshadow warning.

Tue Sep 20 00:15:07 GMT 2011  Olly Betts <olly@survex.com>

        * NEWS: Perhaps the final update for 1.2.0.

Tue Sep 20 00:09:42 GMT 2011  Olly Betts <olly@survex.com>

        * lib/afm2txf.pl: Fix to correctly handle non-ASCII glyphs by using
          glyphshow in the generated PostScript code rather than relying on the
          numeric encoding order of the font to match Unicode (which doesn't
          generally seem to be the case).  Tweak to process files without
          slurping them all into memory where that's easy to do.

Mon Sep 19 23:15:46 GMT 2011  Olly Betts <olly@survex.com>

        * src/fnt.cc: Use FNT_MAXCHAR instead of literal 256.

Mon Sep 19 21:58:50 GMT 2011  Olly Betts <olly@survex.com>

        * buildmacosx.sh: Revert CPP=cpp change - it's not required.  Revert to
          using wx 2.8.11 and 2.8.12 seems to fail to build.  Output of hdid
          can contain spaces as well as tabs (man page only documents tabs) so
          update regexps to take this into account.

Mon Sep 19 11:52:50 GMT 2011  Olly Betts <olly@survex.com>

        * buildmacosx.sh: Add comment noting that Xcode is probably required.
          Since wxWidgets only supports building for a single arch at a time,
          build for i386 by default, which should also work on x86_64.  Pass
          CPP=cpp to wxWidgets configure (not certain if this is actually
          needed, or was something tried on the way to discovering that only
          one -arch option can be passed).

Sun Sep 18 12:24:41 GMT 2011  Olly Betts <olly@survex.com>

        * make_release: No need to force disabling of libavcodec for mingw - it
          gets automatically disable if not present.

Sun Sep 18 12:23:39 GMT 2011  Olly Betts <olly@survex.com>

        * src/moviemaker.cc: Fix disabling of libavcodec-using code when
          libavcodec isn't present.

Sun Sep 18 11:50:06 GMT 2011  Olly Betts <olly@survex.com>

        * NEWS: Update 1.2.0 release date.

Sun Sep 18 11:49:46 GMT 2011  Olly Betts <olly@survex.com>

        * make_release: Disable use of libavcodec for mingw for now.

Sun Sep 18 02:51:52 GMT 2011  Olly Betts <olly@survex.com>

        * make_release: Fix comment typo.

Sun Sep 18 02:50:30 GMT 2011  Olly Betts <olly@survex.com>

        * doc/TODO.htm: Update in preparation for releasing 1.2.

Sun Sep 18 02:49:53 GMT 2011  Olly Betts <olly@survex.com>

        * src/gla-gl.cc: Only try to read the GLX version on platforms which
          use GLX.

Sun Sep 18 02:03:13 GMT 2011  Olly Betts <olly@survex.com>

        * Makefile.am,doc/Makefile.am: Don't list other .in files explicitly in
          EXTRA_DIST.

Sun Sep 18 01:59:49 GMT 2011  Olly Betts <olly@survex.com>

        * lib/Makefile.am: survex.keys.in will get shipped because it is
          used by AC_CONFIG_FILES so there's no need to list it explicitly
          in EXTRA_DIST.

Sun Sep 18 01:56:18 GMT 2011  Olly Betts <olly@survex.com>

        * configure.in,lib/Makefile.am,lib/po-to-msg.pl: Fix .msg file
          generation to work when srcdir != builddir.  Drop the "dontextract"
          mechanism which automatically generates headers to allows building a
          version with translations for the messages for errors in loading the
          messages file, as it doesn't seem worth the effort to get it working
          again.  It's easy to write such a header by hand if you really want
          to do this.

Fri Sep 16 14:26:43 GMT 2011  Olly Betts <olly@survex.com>

        * NEWS,configure.in: Update for 1.2.0.

Fri Sep 16 14:22:20 GMT 2011  Olly Betts <olly@survex.com>

        * lib/icons/Makefile.am,lib/icons/aven.png,lib/icons/aven.svg: Add
          new version of aven icon, redrawn in SVG so it displays nicely at
          larger sizes.

Fri Sep 16 12:55:05 GMT 2011  Olly Betts <olly@survex.com>

        * lib/codes.po,src/cavern.c: Add --3d-version option to allow the user
          to specify the version of the 3d format to output.  (ticket#21)

Fri Sep 16 12:52:55 GMT 2011  Olly Betts <olly@survex.com>

        * src/img.c,src/img.h: Make the highest and lowest valid values for
          img_output_version available in img.h as IMG_VERSION_MIN and
          IMG_VERSION_MAX.

Fri Sep 16 05:49:12 GMT 2011  Olly Betts <olly@survex.com>

        * src/aventreectrl.cc,src/guicontrol.cc,src/mainfrm.cc: Don't use
          deprecated members or methods of wxKeyEvent.

Fri Sep 16 03:36:54 GMT 2011  Olly Betts <olly@survex.com>

        * lib/map.png: Remove scan of map which isn't used and we probably
          don't have rights to redistribute.

Fri Sep 16 03:16:01 GMT 2011  Olly Betts <olly@survex.com>

        * src/mainfrm.cc: If a label isn't valid UTF-8, treat it as CP1252 (the
          Microsoft superset of ISO8859-1).

Fri Sep 16 03:00:51 GMT 2011  Olly Betts <olly@survex.com>

        * src/mainfrm.cc: Remove special handling for toggling "full screen"
          on wxGTK as it's no longer required with modern versions.

Fri Sep 16 02:05:12 GMT 2011  Olly Betts <olly@survex.com>

        * src/gfxcore.cc,src/gfxcore.h,src/mainfrm.cc: Don't redraw the survey
          on every mouse movement in the survey pane unless the measuring line
          is (or just was) active.  (ticket #17)

Thu Sep 15 03:58:59 GMT 2011  Olly Betts <olly@survex.com>

        * src/aven.cc: Comment improvements.

Thu Sep 15 03:51:27 GMT 2011  Olly Betts <olly@survex.com>

        * tests/smoke.tst: aven no longer requires an X display for --help or
          --version, so replace skip of this check with a check that this
          remains the case.

Thu Sep 15 02:27:57 GMT 2011  Olly Betts <olly@survex.com>

        * NEWS: Update from ChangeLog.

Thu Sep 15 02:11:28 GMT 2011  Olly Betts <olly@survex.com>

        * lib/Makefile.am: Distribute codes.po.

Thu Sep 15 02:08:35 GMT 2011  Olly Betts <olly@survex.com>

        * configure.in,survex.spec.in: Default to installing docs into
          /usr/share/doc/survex rather than /usr/doc/survex.

Wed Sep 14 01:57:45 GMT 2011  Olly Betts <olly@survex.com>

        * src/mainfrm.cc: Fix another potential read beyond the end of a
          string.

Wed Sep 14 01:35:20 GMT 2011  Olly Betts <olly@survex.com>

        * src/mainfrm.cc: Fix potential reading off end of string - fix from

Tue Sep 13 22:05:59 GMT 2011  Olly Betts <olly@survex.com>

Tue Sep 13 11:32:18 GMT 2011  Olly Betts <olly@survex.com>

        * src/aven.cc,src/aven.h,src/gla-gl.cc: Explicitly request
          double-buffering, which seems to be needed for systems with GLX >=
          1.3.  Report GLX version and whether double-buffering is in use in
          the about dialog.

Sun Jun 19 11:19:51 GMT 2011  Olly Betts <olly@survex.com>

        * src/gfxcore.cc: No need to specify true to PlayPres - that's the
          default.

Fri Jun 17 06:15:34 GMT 2011  Olly Betts <olly@survex.com>

        * src/gfxcore.cc: Set the play speed to "x1" during video recording.

Fri Jun 17 05:43:12 GMT 2011  Olly Betts <olly@survex.com>

        * src/gfxcore.cc,src/gfxcore.h: Rename 'mpeg' member to 'movie'.

Fri Jun 17 04:30:12 GMT 2011  Olly Betts <olly@survex.com>

        * configure.in,src/moviemaker.cc,src/moviemaker.h: Mostly update movie
          making code to work with current FFmpeg.  Still TODO: convert call
          to img_convert() to use sws_scale() - currently you just get an all
          green movie!

Mon May 30 07:40:12 GMT 2011  Olly Betts <olly@survex.com>

        * buildmacosx.sh: Fix URL for downloading wxWidgets tarball.

          /Volumes/Survex as it won't be if that mount point is already in use.

Thu May 26 12:47:44 GMT 2011  Olly Betts <olly@survex.com>

          wxButton, use the implicit default label, as the wx documentation
          recommends.

Thu May 26 12:28:11 GMT 2011  Olly Betts <olly@survex.com>

        * src/: Remove the unused preferences dialog code - we can easily
          fish it back out of SVN should we want it later, so no point
          having it sitting there making every checkout bigger.

Tue May 24 05:21:52 GMT 2011  Olly Betts <olly@survex.com>

        * configure.in,doc/Makefile.am,doc/survex.1.in: Move survex man page to
          section 7 (since it isn't documenting an actual command).

Tue May 24 05:17:53 GMT 2011  Olly Betts <olly@survex.com>

        * doc/Makefile.am: Write generated man page to a temporary file, then
          atomically rename, to avoid leaving an empty or partial man page
          behind if docbook-to-man dies (I managed to ship an empty cad3d.1 in
          1.1.16).

Sat May 21 22:05:04 GMT 2011  Olly Betts <olly@survex.com>

        * lib/fr.po: Fold in addition of accent from launchpad.

Sat May 21 22:04:31 GMT 2011  Olly Betts <olly@survex.com>

        * lib/messages.txt: Remove as no longer used.

Wed May 18 09:06:19 GMT 2011  Olly Betts <olly@survex.com>

        * lib/,src/mainfrm.cc,src/mainfrm.h: We now use .po and .pot files as
          the master format for storing translations in (rather than
          messages.txt), and then translate these into Survex's .msg format.

Wed May 18 08:37:01 GMT 2011  Olly Betts <olly@survex.com>

        * lib/messages.txt: Fix variant en-us message which ought not be
          different.

Tue May 17 01:24:59 GMT 2011  Olly Betts <olly@survex.com>

        * lib/messages.txt,src/cavern.c: Drop "non-fatal" from the report of
          how many errors there were at the end of the run - it just confuses
          users - we won't even get here if there's a fatal error!
        * lib/messages.txt: Add missing translations of two "Export" variants
          for ca, sk, and ro.

Tue May 17 01:03:06 GMT 2011  Olly Betts <olly@survex.com>

Mon May 16 22:18:53 GMT 2011  Olly Betts <olly@survex.com>

        * buildmacosx.sh: Extract tarball quietly, and just say we're doing
          it.  Add missing quoting to variable expansions.

Mon May 16 05:59:32 GMT 2011  Olly Betts <olly@survex.com>

        * NEWS: Another pre-1.1.16 update.

Mon May 16 05:54:30 GMT 2011  Olly Betts <olly@survex.com>

        * Makefile.am: Include all the available wxstd.mo files into the
          Microsoft Windows installer, rather than trying to just include those
          which we have translations for.  This avoids having to maintain a
          list of which to include, and gives users translations of wxWidgets
          messages even if they don't get Survex messages translated.

Mon May 16 05:53:49 GMT 2011  Olly Betts <olly@survex.com>

        * doc/HACKING.htm: Update version of InnoSetup used.  Note the packages

          Handle &Scaron;, &scaron;, &Zcaron;, &zcaron; for WINCP1252.
        * lib/messages.txt: Use '&rarr;' instead of '->' and '&hellip;' instead
          of '...'.

Sat Oct 16 11:12:42 GMT 2010  Olly Betts <olly@survex.com>

Thu Oct 14 22:48:06 GMT 2010  Olly Betts <olly@survex.com>

        * src/diffpos.c: Handle files with duplicate labels in better - extend
          generates duplicate labels when it breaks a loop.

Wed Oct 13 15:39:04 GMT 2010  Olly Betts <olly@survex.com>

        * make_release: -Dunix when running make distcheck with the

Wed Oct 13 11:19:29 GMT 2010  Olly Betts <olly@survex.com>

        * src/cavernlog.cc: mingw doesn't have _get_wpgmptr() so use the
          deprecated _wpgmptr instead.  mingw doesn't have errno_t so use int
          instead.

Wed Oct 13 10:49:18 GMT 2010  Olly Betts <olly@survex.com>

        * src/cavernlog.cc: (Microsoft Windows) Quote for any meta characters,
          not just space.

Wed Oct 13 10:27:38 GMT 2010  Olly Betts <olly@survex.com>

Thu Oct 07 14:25:13 GMT 2010  Olly Betts <olly@survex.com>

        * src/mainfrm.cc: Use _wfopen() on Microsoft Windows when loading and
          saving presentations so that paths with non-Latin1 characters in can
          be processed.

Thu Oct 07 12:52:22 GMT 2010  Olly Betts <olly@survex.com>

        * configure.in,src/cavernlog.cc: Use getc_unlocked() if available.

Thu Oct 07 12:42:21 GMT 2010  Olly Betts <olly@survex.com>

        * src/cavernlog.cc: Don't call Update() after every line, but only
          when we don't have data from cavern pending.  Hopefully addresses
          ticket#12.

Wed Oct 06 02:25:31 GMT 2010  Olly Betts <olly@survex.com>

        * make_release: Never set CFLAGS or CXXFLAGS in the environment.

        * src/gla-gl.cc,src/gla.h: Check whether blobs and crosses actually
          render correctly as points/point sprites, and if they don't, fall
          back to drawing them with lines.

Tue Oct 05 10:53:56 GMT 2010  Olly Betts <olly@survex.com>

        * src/gla-gl.cc,src/gla.h: Cache the best method for drawing blobs

          src/printwx.cc,survex.iss.in: Use http://survex.com/ rather than
          http://www.survex.com/ - the former is the canonical name and
          www.survex.com just redirects.

Mon Oct 04 09:46:24 GMT 2010  Olly Betts <olly@survex.com>

        * src/mainfrm.cc: Don't offer "All files" wildcard in presentation save
          dialog.

Mon Oct 04 08:19:40 GMT 2010  Olly Betts <olly@survex.com>

        * src/gla-gl.cc: Pass GL_TRUE to OpenGL functions, rather than true.

Sun Oct 03 06:46:03 GMT 2010  Olly Betts <olly@survex.com>

        * src/gfxcore.cc,src/gla-gl.cc,src/gla.h: Use double instead of Double
          in cases where the value isn't being passed to OpenGL.

Sun Aug 22 13:30:54 GMT 2010  Olly Betts <olly@survex.com>

        * src/gla-gl.cc: If we aren't using GL_POINTS for blobs, draw them
          using a series of abutting lines rather than with gluDisk which
          is faster and gives a consistent shape.

Sat Aug 21 14:33:54 GMT 2010  Olly Betts <olly@survex.com>

        * src/gla-gl.cc: Fix another use of GL_POINT_SIZE_RANGE to
          GL_SMOOTH_POINT_SIZE_RANGE.

Sat Aug 21 14:30:56 GMT 2010  Olly Betts <olly@survex.com>

        * src/gla-gl.cc: Fix non-USE_FNT case to work again (it's limited to
          ISO-8859-1 characters though).

Sat Aug 21 13:31:17 GMT 2010  Olly Betts <olly@survex.com>

        * src/gla-gl.cc: Use GL_SMOOTH_POINT_SIZE_RANGE and
          GL_SMOOTH_POINT_SIZE_GRANULARITY instead of GL_POINT_SIZE_RANGE and
          GL_POINT_SIZE_GRANULARITY (unless they aren't defined) as the latter
          two are deprecated in OpenGL >= 1.2.  If GL_ALIASED_POINT_SIZE_RANGE
          is available (OpenGL >= 1.2 again) then report its value in the
          about box.

Fri Aug 20 12:26:40 GMT 2010  Olly Betts <olly@survex.com>

        * doc/3dformat.htm,lib/messages.txt,src/,tests/: New v7 of .3d format
          which stores survey dates as number of days since Jan 1st 1900, so
          we now support dates from 1900-2078 (rather than 1970-2037) with a
          smaller file size.  The img API is now versioned - you can select
          the new "version 1" by compiling with -DIMG_API_VERSION=1, which
          gives the survey dates in days in days1 and days2 instead of as
          time_t values in date1 and date2.  Fixes ticket#14.

Fri Aug 20 12:12:54 GMT 2010  Olly Betts <olly@survex.com>

        * src/osdepend.h: Remove workaround for DOS Turbo C compiler.

Wed Aug 18 02:03:39 GMT 2010  Olly Betts <olly@survex.com>

        * buildmacosx.sh,configure.in,lib/Info.plist.in: Make buildmacosx.sh
          work.

Tue Aug 17 01:43:24 GMT 2010  Olly Betts <olly@survex.com>

        * src/gfxcore.h: "using svx::Point;" gives an error, so use a macro
          instead.

Wed Aug 04 03:27:22 GMT 2010  Olly Betts <olly@survex.com>

        * src/img.c: Fix cast in get16() to be to short not long.

Wed Aug 04 02:32:16 GMT 2010  Olly Betts <olly@survex.com>

        * src/cavernlog.cc,src/cavernlog.h: "Rerun" -> "Reprocess" to follow
          terminology in manual, etc.  Fixes ticket#15.

Wed Jul 28 17:06:49 GMT 2010  Olly Betts <olly@survex.com>

        * tests/: Most tests weren't actually running and testcases (looks like
          a sh portability issue).  Fixed, and fortunately all tests still
          pass.

Mon Jul 26 12:30:43 GMT 2010  Olly Betts <olly@survex.com>

        * doc/manual.sgml: Fix typo "of" -> "on".

Mon Jul 26 11:59:59 GMT 2010  Olly Betts <olly@survex.com>

        * NEWS,configure.in: Update for 1.1.14.

Mon Jul 26 11:53:01 GMT 2010  Olly Betts <olly@survex.com>

        * lib/messages.txt,src/: Remove things we no longer need now we've
          dropped support for RISC OS and DOS.

Mon Jul 26 11:19:40 GMT 2010  Olly Betts <olly@survex.com>

Mon Jul 26 10:23:07 GMT 2010  Olly Betts <olly@survex.com>

        * src/: Strip out "Far" and "Huge" which we no longer need now that
          DOS memory models are no longer relevant.

Mon Jul 26 09:57:37 GMT 2010  Olly Betts <olly@survex.com>

        * configure.in: No need for AC_PROG_MAKE_SET when using automake.

Mon Jul 26 09:48:10 GMT 2010  Olly Betts <olly@survex.com>

        * configure.in,src/useful.h: On little-endian architectures, make
          get16() and get32() inline functions, rather than macros which use 
          a global variable.

Mon Jul 26 09:31:14 GMT 2010  Olly Betts <olly@survex.com>

        * src/useful.c: Remove commented out code.

Mon Jul 26 09:19:19 GMT 2010  Olly Betts <olly@survex.com>

        * configure.in,src/img.c,src/useful.c,src/useful.h: Use AC_TYPE_INT16_T
          and AC_TYPE_INT32_T instead of home-brew equivalents.

Mon Jul 26 08:40:43 GMT 2010  Olly Betts <olly@survex.com>

        * src/listpos.c: In "Station X referred to just once, with an explicit
          prefix - typo?" warning, give file and linenumber where the *equate
          occurred.

Mon Jul 26 08:37:46 GMT 2010  Olly Betts <olly@survex.com>

        * src/readval.c: Fix comment typo.

Mon Jul 26 08:29:41 GMT 2010  Olly Betts <olly@survex.com>

        * src/listpos.c: In "Station X referred to by *entrance or *export but
          never used" warning, give file and linenumber where the *entrance or
          *export occurred.

Mon Jul 26 07:44:26 GMT 2010  Olly Betts <olly@survex.com>

        * src/aventreectrl.cc: Fix double-click handling for survey tree on
          wxMSW >= 2.8.11.

Mon Jul 26 07:25:59 GMT 2010  Olly Betts <olly@survex.com>

        * src/mainfrm.cc: Stop passing wxNO_FULL_REPAINT_ON_RESIZE as it is 0
          on all versions of wxWidgets we support (i.e. 2.6 and later).

Mon Jul 26 07:21:35 GMT 2010  Olly Betts <olly@survex.com>

        * INSTALL,src/: Restore compatibility with wxWidgets 2.6.

Mon Jul 26 06:29:03 GMT 2010  Olly Betts <olly@survex.com>

        * src/netskel.c: In "Unused fixed point" warning, give file and
          linenumber where the "*fix" occurred.

Mon Jul 26 06:24:35 GMT 2010  Olly Betts <olly@survex.com>

        * src/cavernlog.cc: Fix highlighting of links in CavernLog window to
          highlight just <file>:<line> (and not the ': ' after), and to make
          the title for the terminal the warning/error message.  Make the
          checking stricter by checking that the linenumber is a number, to
          avoid false positives.

Mon Jul 26 04:48:12 GMT 2010  Olly Betts <olly@survex.com>

        * Revert this change, as it appears wxMotif does support wxGLCanvas:
        * doc/manual.sgml: wxMotif apparently doesn't support wxGLCanvas, which
          is required by Aven in 1.1.x, so remove mention of Motif from manual.

Mon Jul 26 03:24:38 GMT 2010  Olly Betts <olly@survex.com>

        * src/: Add "Rerun" and "OK" buttons to the CavernLog window (as
          appropriate).  (Addition of "OK" button fixes ticket#13).  Fix up
          handling of splitter window to fix poor handling of various cases.

Sun Jul 25 15:32:42 GMT 2010  Olly Betts <olly@survex.com>

        * src/mainfrm.cc,src/mainfrm.h: Clean up code which sorts out loading
          a file (and processing it first if necessary).

Sun Jul 25 07:20:05 GMT 2010  Olly Betts <olly@survex.com>

        * src/cavernlog.h: Fix filename in comment at top.

Sun Jul 25 07:17:20 GMT 2010  Olly Betts <olly@survex.com>

        * src/cavernlog.cc: Don't double escape the contents of href and target
          in links in the log.

Sun Jul 25 06:32:24 GMT 2010  Olly Betts <olly@survex.com>

        * src/cavernlog.cc: Remove commented out calls to set the input
          encoding of the HTML parser - we now always escape non-ASCII
          characters as HTML entities.

Fri Jul 23 14:15:25 GMT 2010  Olly Betts <olly@survex.com>

        * src/cavernlog.h: Improve doc comment for process() method.

Fri Jul 23 12:38:43 GMT 2010  Olly Betts <olly@survex.com>

        * src/printwx.cc,src/printwx.h: Don't compile in the preview code when
          we disable the preview feature.

Fri Jul 23 12:15:31 GMT 2010  Olly Betts <olly@survex.com>

        * src/printwx.cc: The Gnome print dialog has its own preview window
          so suppress ours if using the Gnome one.

Fri Jul 23 11:21:52 GMT 2010  Olly Betts <olly@survex.com>

        * configure.in: Update the wx-config probing code - wxmac-config etc
          aren't present with newer wxWidgets versions.

Fri Jul 23 05:55:37 GMT 2010  Olly Betts <olly@survex.com>

        * buildmacosx.sh: Update to use WX_CONFIG not WXCONFIG.  Update to
          use a Unicode build.  If building a private wx, use wx 2.8.11 not
          2.7.0-1 (and don't replace carbon-glcanvas.cpp with our own version).

Sat Jul 10 12:15:23 GMT 2010  Olly Betts <olly@survex.com>

        * src/cavernlog.cc: Set the select timeout before calling wxYield()
          when waiting for output from cavern to 0.1s instead of 0.00001s to
          avoid yielding excessively on slower machines where this is likely
          to really slow things down.  Call Scroll() only once per line in
          the case where we are updating the scrollbar position.  Call
          Update() instead of wxYield() after each line, since that's enough
          to get the window updated.  Remove unused assignment "ch = left;"
          at end of loop.

Fri Jul 09 14:42:47 GMT 2010  Olly Betts <olly@survex.com>

        * configure.in: Link aven with -lGLU which SuSE Linux needs.

Fri Jul 09 14:31:39 GMT 2010  Olly Betts <olly@survex.com>

        * src/mainfrm.cc: Highlight stations matching any current search when a
          file is loaded.  (ticket#9)

Thu Jul 01 12:20:58 GMT 2010  Olly Betts <olly@survex.com>

        * survex.iss.in: Clean up comments from over-enthusiastic search and
          replace which modified comments as well as code.

Thu Jul 01 10:15:06 GMT 2010  Olly Betts <olly@survex.com>

        * src/gfxcore.h: Work around Mac OS X polluting the global namespace
          with a "Point" class.

Thu Jul 01 10:10:45 GMT 2010  Olly Betts <olly@survex.com>

        * src/Makefile.am: Remove FIXME which has already been resolved.

Fri Jun 18 11:04:35 GMT 2010  Olly Betts <olly@survex.com>

        * doc/manual.sgml: wxMotif apparently doesn't support wxGLCanvas, which
          is required by Aven in 1.1.x, so remove mention of Motif from manual.

Fri Jun 18 03:03:55 GMT 2010  Olly Betts <olly@survex.com>

        * doc/manual.sgml,src/aventreectrl.cc,src/gfxcore.cc,src/mainfrm.h:
          Correctly capitalise "GTK".

Fri Jun 18 02:58:06 GMT 2010  Olly Betts <olly@survex.com>

        * doc/manual.sgml: Note that on Linux we only regularly test builds
          with the GTK+ version (change taken from 1.0).

Wed Jun 16 04:44:26 GMT 2010  Olly Betts <olly@survex.com>

        * doc/Makefile.am: Use stampfile to stop unwanted rebuilds of the HTML
          version of the manual.

Wed Jun 16 02:59:48 GMT 2010  Olly Betts <olly@survex.com>

        * configure.in: Only ask for core, gl, and html wx libs to avoid
          linking to a load of others we don't use.

Tue Jun 15 17:01:41 GMT 2010  Olly Betts <olly@survex.com>

        * INSTALL: Update.

Tue Jun 15 16:53:28 GMT 2010  Olly Betts <olly@survex.com>

        * src/aven.cc: Fix to work with wxWidgets 2.6 too.

Tue Jun 15 15:38:49 GMT 2010  Olly Betts <olly@survex.com>

        * lib/survex-aven.desktop,lib/survex-svxedit.desktop: Merge in .desktop
          file updates from 1.0.39.1-4 Debian package.

Tue Jun 15 14:40:04 GMT 2010  Olly Betts <olly@survex.com>

        * doc/Makefile.am: Fix lingering references to @DOCS_OTHER@.

Tue Jun 15 14:32:55 GMT 2010  Olly Betts <olly@survex.com>

        * NEWS: Update from ChangeLog.

Tue Jun 15 14:09:29 GMT 2010  Olly Betts <olly@survex.com>

        * Makefile.am,configure.in,doc/Makefile.am,make_release: Scrap the
          "alternative manual formats" zip file - people will generally just
          want one of them, so downloading several together isn't very useful.
          Replace PostScript version of manual with a PDF version (more
          compact and more people will have software to read PDF).  Don't
          generate RTF format by default as PDF is more useful if you want
          a formatted version to print.

Tue Jun 15 13:36:30 GMT 2010  Olly Betts <olly@survex.com>

        * doc/manual.sgml: Merge the "Contributing" section into the "Mailing
          List" section.

Tue Jun 15 12:57:13 GMT 2010  Olly Betts <olly@survex.com>

        * Makefile.am,make_release: Just produce a zip file with the
          alternative manual formats - a self-extracting .exe is harder to
          use on other platforms, and most people have a zip file extractor
          installed.

Tue Jun 15 12:36:13 GMT 2010  Olly Betts <olly@survex.com>

        * survex.spec.in: Update survex.com URLs to drop "www.".  Update
          wxGTK dependency to >= 2.6.0.  Reenable "BuildRequires:" as
          the issue with building the package on Debian is no longer
          relevant.

Tue Jun 15 12:35:19 GMT 2010  Olly Betts <olly@survex.com>

        * doc/manual.sgml: Update (C) years.  "MacOS X" -> "Mac OS X".

Tue Jun 15 12:13:42 GMT 2010  Olly Betts <olly@survex.com>

        * doc/manual.sgml: Remove out of date postal addresses - we can
          probably safely assume people have email these days.  Direct
          people to the mailing list since they are likely to get a
          quicker response rather than mailing individuals.  Remove
          mention of a paper mailing list.  Remove mention of sending
          us a floppy (!) or blank CDR to get a version as I can't recall
          the last time I gave someone a copy on physical media.

Tue Jun 15 11:22:56 GMT 2010  Olly Betts <olly@survex.com>

        * Makefile.am,make_release: I can't persuade rpmbuild to work sanely,
          and people can just as easily build binary RPMs from the source
          tarball as from the srpm, so just remove the rpm target from the
          makefile and code which uses it from make_release - it's less to
          have to maintain too.

Tue Jun 15 10:59:12 GMT 2010  Olly Betts <olly@survex.com>

        * make_release: Use "set -e" rather than checking the exit codes of
          commands.  -t no longer disables targets - set mk to do that.

Tue Jun 15 09:41:11 GMT 2010  Olly Betts <olly@survex.com>

        * make_release: Fix defaulting of list of things to do.

Tue Jun 15 09:12:00 GMT 2010  Olly Betts <olly@survex.com>

        * src/gdtconvert: Add "Generated" comment to output file.

Tue Jun 15 09:10:02 GMT 2010  Olly Betts <olly@survex.com>

        * src/gdtconvert: Add GPL license boilerplate.

Tue Jun 15 08:53:28 GMT 2010  Olly Betts <olly@survex.com>

        * src/gettexttomsg.pl,src/wx.h: Add GPL boilerplate to files which were
          missing it.

Tue Jun 15 08:46:28 GMT 2010  Olly Betts <olly@survex.com>

        * src/: Update FSF address in licence notices.

Tue Jun 15 08:06:09 GMT 2010  Olly Betts <olly@survex.com>

        * src/guicontrol.cc: Allow "Toggle Fullscreen" to work even if no
          survey is loaded now that we persist the window size between
          invocations.

Tue Jun 15 08:03:53 GMT 2010  Olly Betts <olly@survex.com>

        * src/gla-gl.cc: Use GL_BLEND rather than GL_ALPHA to work better with
          anti-aliased TXF files.

Tue Jun 15 07:59:09 GMT 2010  Olly Betts <olly@survex.com>

        * src/fnt.cc: Use font size from txf file rather than trying to
          calculate it from the texture fragment sizes.

Tue Jun 15 07:48:13 GMT 2010  Olly Betts <olly@survex.com>

        * lib/Makefile.am,lib/TexFont.h,lib/gentexfont.c: Generate aven.txf with
          afm2txf.pl instead of gentexfont because gentexfont's licence doesn't
          allow distribution of modified versions.

Tue Jun 15 07:43:48 GMT 2010  Olly Betts <olly@survex.com>

        * lib/afm2txf.pl: Add support for -o option to specify output .txf
          file.

Tue Jun 15 07:10:16 GMT 2010  Olly Betts <olly@survex.com>

        * lib/afm2txf.pl: Sanitise $FONT to ensure it doesn't contain a '/'.
          Remove the temporary .ppm file at the end.

Tue Jun 15 06:13:30 GMT 2010  Olly Betts <olly@survex.com>

        * lib/afm2txf.pl: Fix alignment of characters, backported from PLIB
          SVN.

Tue Jun 15 05:05:05 GMT 2010  Olly Betts <olly@survex.com>

        * lib/afm2txf.pl: Quote $FONT when passing to external commands.

Tue Jun 15 04:24:33 GMT 2010  Olly Betts <olly@survex.com>

        * lib/afm2txf.pl: Change character 96 from "grave" to "quoteleft".

Tue Jun 15 04:22:59 GMT 2010  Olly Betts <olly@survex.com>

        * lib/afm2txf.pl: Extend to cover ISO-8859-1, not just ASCII.

Tue Jun 15 04:08:34 GMT 2010  Olly Betts <olly@survex.com>

        * lib/afm2txf.pl: Clean up trailing whitespace.

Tue Jun 15 04:02:40 GMT 2010  Olly Betts <olly@survex.com>

        * lib/afm2txf.pl: Add GPL script for creating txf files.

Mon Jun 14 06:33:11 GMT 2010  Olly Betts <olly@survex.com>

        * lib/splash.png: Remove now unused graphical splash screen (it has
          hardcoded (C) details, which wasn't a good approach).

Mon Jun 14 05:20:44 GMT 2010  Olly Betts <olly@survex.com>

        * src/fnt.cc: Handle the left bearing and character width correctly.

Mon Jun 14 04:44:22 GMT 2010  Olly Betts <olly@survex.com>

        * src/fnt.cc: Change back to not using GL_COLOR_INDEX, but with still
          being able to set the font texture from a byte array.

Mon Jun 14 04:23:22 GMT 2010  Olly Betts <olly@survex.com>

        * src/fnt.h,src/gla-gl.cc: Pass the length of the string to
          fntTexFont::puts() rather than recalculating it inside the
          method.

Sun Jun 13 12:57:08 GMT 2010  Olly Betts <olly@survex.com>

        * src/mainfrm.cc: Fix switching to and from the CavernLogWindow pane
          to use wxSplitterWindow::ReplaceWindow() which fixes various issues
          with sizing and resizing of the panes.

Sun Jun 13 12:23:23 GMT 2010  Olly Betts <olly@survex.com>

        * src/: Add wmsg_cfgpth() which caches the result of msg_cfgpth() as
          a wxString.

Sun Jun 13 06:57:07 GMT 2010  Olly Betts <olly@survex.com>

        * src/cavernlog.cc,src/gla-gl.cc,src/mainfrm.cc: wxString::fn_str() on
          wxmsw returns a wide string, which doesn't work with fopen(), etc, so
          call char_str() instead for now.

Sun Jun 13 05:41:30 GMT 2010  Olly Betts <olly@survex.com>

        * src/printwx.cc: Use wxString::FromAscii() for the units on the scale
          bar which we know to be ASCII.  No need to use msgPerm() for a
          message we assign to a wxString.

Sun Jun 13 04:44:30 GMT 2010  Olly Betts <olly@survex.com>

        * src/mainfrm.cc,src/printwx.cc: Use wxFileName::SplitPath() instead of
          baseleaf_from_fnm().

Sun Jun 13 00:57:11 GMT 2010  Olly Betts <olly@survex.com>

        * src/export.cc,src/gfxcore.cc: wxString::fn_str() on wxmsw returns
          a wide string, which doesn't work with fopen(), etc, so call
          char_str() instead for now.

Sat Jun 12 15:07:54 GMT 2010  Olly Betts <olly@survex.com>

        * src/aven.cc: We can rely on our message catalog being UTF-8 so use
          wxString::FromUTF8() instead of wxConvUTF8.

Sat Jun 12 14:26:32 GMT 2010  Olly Betts <olly@survex.com>

        * src/gfxcore.cc: Use wxString::FromAscii() to convert date to
          wxString.

Sun Jun 06 09:36:06 GMT 2010  Olly Betts <olly@survex.com>

        * src/Makefile.am: Use wx-config's --rescomp option to get the command
          and options needed to turn .rc files into object files.

Fri Jun 04 15:32:27 GMT 2010  Olly Betts <olly@survex.com>

        * survex.iss.in: Specify "LZMANumFastBytes=273" which shaves a small
          amount of the installer size.  Specify "DisableWelcomePage=yes"
          which is apparently in line with what other modern installers do.

Fri Jun 04 14:32:04 GMT 2010  Olly Betts <olly@survex.com>

        * configure.in,make_release,make_release.in: We no longer need VERSION
          in make_release, so no need to generate it from configure.

        * Makefile.am,xvfb-run: We no longer need an X display to run ISCC
          under Wine, so just run wine directly and removed version of
          Debian's xvfb-run script.
        * make_release.in: Pass variables to configure on the command line
          rather than in the enviornment.  Running "make distcheck" no longer
          fails extend.tst, so remove comment about that.  Use case rather
          than expr to check what we've been asked to build.  Update to use
          unicode wx-config script for wxmsw.  The wxmsw build spews warnings
          about aliasing issues, so turn on -fno-strict-aliasing to avoid any
          potential bugs from that.  Enable -Werror for the wxmsw build.
        * Makefile.am: Update list of wxstd.mo files we package for wxmsw
          (add pt and sk) and where we copy them from.  Copy the unofficial
          InnoSetup i18n files (.isl) from lib.

Fri Jun 04 13:40:35 GMT 2010  Olly Betts <olly@survex.com>

        * doc/HACKING.htm: Update InnoSetup info.

Fri Jun 04 13:07:01 GMT 2010  Olly Betts <olly@survex.com>

        * survex.iss.in: Update for InnoSetup 5.3.9.
        * lib/English_GB.isl,lib/Romanian-7-5.1.11.isl: Check in the unofficial
          i18n files for InnoSetup which we use.

Fri Jun 04 13:05:18 GMT 2010  Olly Betts <olly@survex.com>

        * src/Makefile.am: Update path to wx RC file.

Fri Jun 04 12:44:39 GMT 2010  Olly Betts <olly@survex.com>

        * src/mainfrm.cc: Explicitly construct temporary wxString() which
          is needed to avoid overload ambiguity under __WXMSW__.

Fri Jun 04 12:41:59 GMT 2010  Olly Betts <olly@survex.com>

        * src/cavernlog.cc: Add missing wxT() to string and character
          constants only used in __WXMSW__ build.

Fri Jun 04 12:19:18 GMT 2010  Olly Betts <olly@survex.com>

        * src/aven.cc: wxWidgets now has a Slovak translation, so remove the
          kludge to substitute Czech if Slovak isn't found.

Fri Jun 04 05:08:14 GMT 2010  Olly Betts <olly@survex.com>

        * src/aboutdlg.cc: Fix character constant to be a string constant when
          building under WXMSW.

Thu Jun 03 13:53:57 GMT 2010  Olly Betts <olly@survex.com>

        * NEWS: Update from ChangeLog for 1.1.13.

Thu Jun 03 12:25:14 GMT 2010  Olly Betts <olly@survex.com>

        * Makefile.am,configure.in,debian/Makefile.am,debian/changelog: Remove
          .deb building machinery from upstream Makefile.

Thu Jun 03 12:14:16 GMT 2010  Olly Betts <olly@survex.com>

        * make_release.in: Remove ancient workaround for getting wine to work.
          Remove .deb building machinery.  Reenable distcheck to see if the
          problem with extend.tst has gone away.  Update mingw cross-building
          machinery.

Wed Jun 02 13:30:28 GMT 2010  Olly Betts <olly@survex.com>

        * configure.in,doc/GPL.htm,doc/index.htm.in: Remove HTML version of GPL
          - just link to the FSF's page.

Wed Jun 02 13:26:55 GMT 2010  Olly Betts <olly@survex.com>

        * configure.in,make_release,make_release.in,update-debcl.pl: Use dch to
          update debian/changelog.

Wed Jun 02 12:59:33 GMT 2010  Olly Betts <olly@survex.com>

        * configure.in,doc/Makefile.am,doc/cl2html.pl,doc/index.htm.in: Stop
          generating an HTML version of the ChangeLog - it's too low level to
          be of interest to non-developers, and developers can look at the
          source code.

Wed Jun 02 09:38:25 GMT 2010  Olly Betts <olly@survex.com>

        * src/cavernlog.cc: Whitespace tweaks.

Wed Jun 02 09:28:37 GMT 2010  Olly Betts <olly@survex.com>

        * src/aboutdlg.cc,src/aboutdlg.h: Use standard button for "Copy" in
          About dialog.  Change "OK" button to "Close" since nothing is being
          confirmed by clicking it.  Call "Flush()" in wxTheClipboard to try
          to make the copied text persist after aven is closed, though this
          seems to currently do nothing on wxGTK at least.

Tue May 18 12:59:00 GMT 2010  Olly Betts <olly@survex.com>

        * doc/HACKING.htm: Note jadetex needed.
          Note autoconf 2.64 works well.

Tue May 18 02:06:00 GMT 2010  Olly Betts <olly@survex.com>

        * src/fnt.cc: Remove now superfluous ().

Mon May 17 14:33:00 GMT 2010  Olly Betts <olly@survex.com>

        * debian/Makefile.am: Update EXTRA_DIST

Mon May 17 05:38:00 GMT 2010  Olly Betts <olly@survex.com>

        * src/cavernlog.cc: Fix small memory leak

Mon May 17 05:33:00 GMT 2010  Olly Betts <olly@survex.com>

        * src/img.c: Don't leak filename_opened member.

Mon May 17 05:13:00 GMT 2010  Olly Betts <olly@survex.com>

        * src/gfxcore.cc: Initialise all GfxCore's member variables so we
          don't use them uninitialised.

Mon May 17 05:11:00 GMT 2010  Olly Betts <olly@survex.com>

        * src/gfxcore.h: Declare constants with enum rather than #define so
          they automatically get allocated unique values, and so they show up
          in the debugger.

Mon May 17 02:39:00 GMT 2010  Olly Betts <olly@survex.com>

        * src/fnt.cc: Make the map array static const

Mon May 17 02:30:00 GMT 2010  Olly Betts <olly@survex.com>

        * src/fnt.cc: Set the font texture with GL_COLOR_INDEX so we can
          use a "byte format" font file without any translation, while a
          "bitmap format" font file needs a temporary array half the size.

Mon May 17 00:56:00 GMT 2010  Olly Betts <olly@survex.com>

        * src/gfxcore.cc: Initialise 3 flags when we load a survey to avoid
          using them potentially uninitialised.

Sun May 16 14:39:00 GMT 2010  Olly Betts <olly@survex.com>

        * src/mainfrm.cc: Fix cavern log window to behave if passed a .svx
          file on the command line.

Sun May 16 14:27:00 GMT 2010  Olly Betts <olly@survex.com>

        * configure.in: Update copyright years.

Sun May 16 14:23:00 GMT 2010  Olly Betts <olly@survex.com>

        * configure.in, src/aboutdlg.cc, src/aboutdlg.h, src/aven.cc,
          src/aven.h, src/avenprcore.cc, src/avenprcore.h,
          src/cavernlog.cc, src/cavernlog.h, src/export.cc, src/fnt.h,
          src/gfxcore.cc, src/gla-gl.cc, src/gla.h, src/guicontrol.cc,
          src/log.cc, src/mainfrm.cc, src/mainfrm.h, src/namecmp.h,
          src/printwx.cc, src/printwx.h:
          + Fix to build with a "unicode" build of wx.
          + Add "Copy" button to the About dialog to copy the system info
            to the clipboard.
          + List OpenGL extensions last, since there are usually lots of
            them with a modern gfx card.
          + When processing survey data, auto-scroll the log window until
            we've reported a warning or error.
          + Put the survey data log window in a splitter in the standard
            frame rather than having a separate frame for it.

Sat Apr 17 12:13:00 GMT 2010  Olly Betts <olly@survex.com>

        * src/aboutdlg.cc: Add case for "GTK+ >= 2.6".

Sat Apr 17 12:12:00 GMT 2010  Olly Betts <olly@survex.com>

        * src/aboutdlg.cc: Build string using preprocessor string
          concatenation rather than runtime appending, where possible.

Sat Apr 17 12:00:00 GMT 2010  Olly Betts <olly@survex.com>

        * src/aboutdlg.cc: Update (C) date.

Sat Apr 17 11:59:00 GMT 2010  Olly Betts <olly@survex.com>

        * src/aboutdlg.cc, src/aboutdlg.h: Use a wxTimer instead of idle
          events to avoid spinning on the CPU.

Sat Apr 17 11:41:00 GMT 2010  Olly Betts <olly@survex.com>

        * configure.in: New preferred env var for wx-config script is
          WX_CONFIG.  WXCONFIG still supported for compatibility.

Tue Jul 28 08:16:00 GMT 2009  Olly Betts <olly@survex.com>

        * src/mainfrm.cc: The presentation filename now defaults to using
          the basename of the currently loaded dataset, but we always prompt
          before we first save with such a name.

Tue Jul 28 04:37:00 GMT 2009  Olly Betts <olly@survex.com>

        * configure.in: Add comment to explain why we call wx-config twice.

Tue Jul 28 04:36:00 GMT 2009  Olly Betts <olly@survex.com>

        * src/datain.c: Use fputs(m, f) instead of fprintf(f, m) in case m
          contains '%' (m comes from the messages file, so this isn't
          exploitable by sending someone a "bad" .svx or .3d file).

Mon Jul 27 03:29:00 GMT 2009  Olly Betts <olly@survex.com>

        * src/mainfrm.cc: Fix to open rather than save when doing "open
          presentation" with wxmotif.

Thu Mar 05 01:45:00 GMT 2009  Olly Betts <olly@survex.com>

        * doc/3dformat.htm: Document that this is version 6 and when we
          started to use it.

Mon Dec 15 10:34:00 GMT 2008  Olly Betts <olly@survex.com>

        * src/gla-gl.cc: When saving a screenshot, perform the vertical
          flip of the image data in-place rather than using wxImage::Mirror()
          which creates a whole new wxImage object.

Fri Dec 12 11:12:00 GMT 2008  Olly Betts <olly@survex.com>

        * src/cad3d.c, src/export.cc: Fix export to SVG when a label
          contains a '%' character.

Fri Dec 12 06:30:00 GMT 2008  Olly Betts <olly@survex.com>

        * configure.in: Add AM_PROG_CC_C_O which newer autoreconf warns is
          needed.

Fri Dec 12 06:28:00 GMT 2008  Olly Betts <olly@survex.com>

        * configure.in: Remove AC_SUBST of CRLIB and CROBJX which are no
          longer set or used.

Fri Dec 12 06:03:00 GMT 2008  Olly Betts <olly@survex.com>

        * NEWS, buildmacosx.sh, configure.in, desc-aven.txt, doc/TODO.htm,
          doc/manual.sgml, doc/survex.ent, lib/messages.txt,
          src/aboutdlg.cc, src/aven.cc, src/aven.h, src/gfxcore.cc,
          src/mainfrm.cc, src/printwx.cc, src/printwx.h, src/wx.h: Say
          "wxWidgets" instead of "wxWindows" consistently.
          Require wxWidgets 2.6.0 or newer - 2.4 is really old now.

Mon Mar 31 01:53:00 GMT 2008  Olly Betts <olly@survex.com>

        * doc/3dformat.htm: Update for v6 format from Mike McCombe

Fri Sep 07 18:29:00 GMT 2007  Olly Betts <olly@survex.com>

        * src/gla-gl.cc: Calling glGetError() resets the error state, so we
          need to store the value in a variable rather than calling it twice!

Fri Sep 07 13:54:00 GMT 2007  Olly Betts <olly@survex.com>

        * src/gla-gl.cc: Add missing CHECK_GL_ERROR() calls and correct
          some which had the wrong descriptions.
          Use GL_POINT_SPRITE and GL_COORD_REPLACE instead of
          GL_POINT_SPRITE_ARB and GL_COORD_REPLACE_ARB.  They have the same
          numeric values, so the shorter (now official) names are better.

Fri Sep 07 13:31:00 GMT 2007  Olly Betts <olly@survex.com>

        * src/Makefile.am, src/gfxcore.cc, src/gfxcore.h, src/gla-gl.cc,
          src/gla.h, src/matrix4.cc, src/matrix4.h, src/quaternion.cc,
          src/quaternion.h: Just set the pan and tilt directly as OpenGL
          rotations rather than messing around setting up and then decoding a
          quaternion.  This fixes some glitches when tilting while looking
          east, and eliminates 2 source files and 2 headers!

Sat Feb 10 13:56:00 GMT 2007  Olly Betts <olly@survex.com>

        * NEWS, configure.in, src/aven.cc, src/wx.h:
          (Unix version): aven: Fix display of degree symbol in status bar and
          messages with accented characters in.
          (Mac OS X version): Require at least wxWidgets 2.5.1.

Sat Feb 10 13:46:00 GMT 2007  Olly Betts <olly@survex.com>

        * src/message.c: Test S_ISREG since that's what we use here

Sat Feb 10 13:37:00 GMT 2007  Olly Betts <olly@survex.com>

        * src/message.c: Always use utf-8 for aven on unix
