3        * lib/icons/Makefile.am,lib/icons/solid-surface.png,
4          lib/icons/solid_surface.xpm,lib/survex.pot,src/: Add UI for toggling
5          terrain on and off.
6        * src/gfxcore.cc,src/gfxcore.h,src/mainfrm.h: Terrain data work in

[a5670c7]9Changes in 1.2.18 (2015-03-10):
[0adeec6]10
[dd65182]11* aven: Add a menu item and toolbar button to show the cavern log window if the
12  currently shown survey data was processed by aven.  Reported by Hugh St
13  Lawrence in #47, and by Dave Clucas and others previously on the list.
14
[0adeec6]15* aven: Add "Save Log" button to Aven's cavern log window.
[dd65182]16
[2595419]17* aven: Add "Colour by Gradient" and "Colour by Length".
[0adeec6]18
[dd65182]19* aven: Make the button to dismiss the "About" dialog "OK" rather than "Close",
20  which seems more logical, and also allows the dialog to be closed by pressing
21  "Escape".
22
23* aven: Don't round bearing and tilt angles to integers when printing and
24  exporting.
25
26* aven: In cavern log window, highlight "error" markers in red and "warning"
27  markers in orange.
28
29* aven: Aven's support for reading colours and font sizes for printouts from
30  print.ini has never worked - the contents of the ini files are ignored due to
31  a bug which has been there since the code was added in 2005 - but nobody has
32  ever complained.  So just strip out that code entirely - we should support
33  setting the colours and font sizes, but a GUI interface for setting them
34  would be better.
35
36* aven: Rework code to read cavern's output.  In particular, we no longer mix
37  buffered I/O with select() on the file descriptor.
38
39* aven: Fix to compile with a Unicode build of wxWidgets 2.8.  Reported by Bill
40  Gee.
41
42* aven: Add JSON export.
43
[0476b10]44* aven: Take the width of the messages used above the compass and clino into
45  account when calculating how much space to allow for them - now the labels
46  won't overlap or be cut off in translations where they are long.
47
[a5670c7]48* cavern: Use the currently set units when outputting measurements in warnings,
49  errors, and the stats at the end of the run.
50
[0476b10]51* cavern: Include column number when a *include file isn't found.
52
53* cavern: Show 'error' in front of error messages, like we show 'warning' in
54  front of warnings.  Fixes #48, reported by Wookey.
55
[2595419]56* findentrances: If the 3d file specifies the coordinate system, use it.
57
[a5670c7]58* (Microsoft Windows version): Add code page 1252 mappings for fancy quotes.
59
60* Transliterate gradient and infinity symbols if the current character set
61  lacks them.
62
63* Add SVG version of .plt icon.
64
65* cavern: Warn if fore and back measurements differ by more than 3 SDs, rather
66  than just by 2 SDs.
67
68* doc/manual.sgml: Add complete list of quantities you can set SDs for.  Thanks
69  for Wookey for highlighting that the previous list was incomplete.
70
71* doc/manual.sgml: Document averaging of a group of repeated readings.
72
[0476b10]73* doc/manual.sgml: Add a link to the sample data from the manual.
[a5670c7]74
[0476b10]75* doc/manual.sgml: Remove references to contact addresses which are no longer
76  there.  Remove offer to post people floppies, and references to a CD image
77  which isn't available for download.
[a5670c7]78
[0476b10]79* Remove non-breaking spaces from the diffpos and extend manual pages, as they
80  actually make the output formatting worse (presumably these used to work
81  around a since-fixed bug in one of the docbook processing tools).
82
83* doc/TODO.htm: "Save cavern log from aven" now implemented.
[a5670c7]84
[dd65182]85* If we run out of memory while reading a processed survey data file, include
86  the filename in the error message.
87
88        * lib/: More translation updates.
89
90        * lib/el.po: Fix language code in file to be 'el'.
91
92        * lib/hu.po: Change '...' to ellipses.
93        * lib/hu.po: Add missing quotes.
94        * lib/hu.po: Use curly double quotes.
95        * lib/hu.po: Remove erroneous quotes from message.
96
97        * lib/ru.po: Merge more translation updates from "vsuhachev".
98
99        * lib/id.po: Merged translation updates from "Cave ID" - all messages
100          are now translated into Indonesian!
101
[2595419]102* doc/manual.sgml: Document averaging of a group of repeated readings.
103
[dd65182]104        * doc/TODO.htm: Update.
105
[1646310]106Changes in 1.2.17 (2015-02-24):
[a6064e2]107
108* MacOS X version:
109
110  + Update INSTALL file with current status.
111
[e067870]112  + Aven.app now has a custom icon.
[9e053fc]113
[e067870]114  + Add icons for all the filetypes supported.
115
116  + Add Finder actions for .svx, .3d, .plt and .pos files.
[9e053fc]117
118  + aven: Hide the status bar and tool bar in Full Screen mode, as wx doesn't
119    currently do this for us.
120
[a6064e2]121  + aven: Fix short-cut for toggling Full Screen mode.
122
123  + aven: Make "About" menu item appear.
124
[9e053fc]125  + aven: Fix "Close" button in about dialog.
126
127  + aven: Make custom cursors black with a white outline to match the standard
128    OS X cursor.
129
[e067870]130  + svxedit: Now wrapped up in an application bundle as svxedit.app.  It
131    still doesn't really work like a standard app though - e.g. you can't load
132    files from Finder (instead run svxedit.app and use File->Open), the font
133    size of most menu items is wrong, the icon for the app is the wish icon
134    rather than the svxedit icon, shortcuts use Ctrl not the Cmd key, and
135    probably more.  I'd probably recommend using another editor (OS X comes
136    with TextEdit.app for example).
137
138  + The documentation is now in a "Docs" directory alongside the apps, rather
139    than in the rather less obvious "share/doc/survex" directory.
140
[a6064e2]141  + Default to building for x86_64, since all modern Macs are 64 bit.
142
[9e053fc]143  + Disable use of liblzma when building wxWidgets for OS X, which was
144    preventing the build from working on OS X 10.6.8.
145
146  + Download wx sources from SF via redirecting link.  Thanks to David A.
147    Riggs.
148
149  + buildmacosx.sh: Handle the mount point for the disk image containing a
150    space.
151
[4baea3a]152  + Link with a static build of PROJ for doing coordinate system conversions.
[9e053fc]153
154  + Build wx with --disable-webview to avoid a compilation failure on OS X
155    10.10.1.
156
157  + Use wx-config --cc and --cxx to get the compilers to use for building
158    everything else, as wx adds options to them which otherwise cause linking
159    errors.
160
[4baea3a]161  + The diskimage (.dmg) file is now compressed with bzip2, which gives a
162    smaller download.  This means OS X 10.4 is required, but we probably
163    already need at least 10.5 because that's the minimum version which the
164    wxWidgets build supports by default.
165
[e067870]166  + Remove unused files and copies of files from the diskimage.
167
[a6064e2]168* cavern: If the same leg is repeated consecutively, average the readings and
169  treat as a single leg.
170
[9e053fc]171* dump3d: Report SEPARATOR used by the file being read.
172
173* aven.svg: Fix visual glitch in SVG icon for aven.  Noted by David A. Riggs.
174
175* aven:
176
177  + Greatly reduce flicker when mouse is moved to the top of the screen in full
178    screen mode and the menu bar reappears.
179
180  + For export formats where scaling is supporting, aven now actually uses the
181    scale specified in the export dialog (previously it ignored this and used
182    1:500).
183
184  + Reimplement animation so that it's based on angular change per unit of
185    elapsed time, rather than averaging the time take for the last two scene
186    redraws.  This gives smoother animation in the face of variable load and
187    scene redraw time, and should be more consistent between platforms.
188
189  + Switching to a point of the compass during auto-rotation now jumps straight
190    there rather than the two animations fighting.
191
192  + Reduce the maximum auto-rotation speed, as the previous limit was uselessly
193    fast.
194
195  + Disable stepping the rotation angle when animating (previously we only did
196    when rotating).
197
[1646310]198  + Speed up start-up a bit - rather than loading icons from individual PNG
199    files on disk, compile them into the aven binary.
200
201* (Unix version): Add "MimeType" field to desktop files so that file
202  associations work out of the box with modern desktop environments.
203
204* Add start of Hungarian translation from Imre Balogh.
205
206* Merge in many updates to the Russian translation from "vsuhachev".
207
208* Assorted minor updates to other translations.
209
210* Create scalable (SVG) versions of file type icons.
[e067870]211
[a6064e2]212* doc/manual.sgml: Remove $Id and $Date markers, as they don't get expanded now
213  we're using git.
214
[1646310]215* tests/: Improve test coverage in a few places:
216
217  + Extend tests of fore and back sights to test calibration of the back
218    compass.
219
220  + Test "Can't calibrate angular and length quantities together" error.
221
222  + Check that "*set names ." works when "." is also the decimal point.
[a6064e2]223
[03d0e8b]224Changes in 1.2.16 (2014-10-17):
[9aa10ad]225
226* aven: Add KML export (stations only currently).
227
[f480117d]228* aven: Allow measuring line to measure from anonymous stations.  (Fixes #44)
229
[9aa10ad]230* aven: Fix corrupted names in exported files.
231
232* aven: Fix error log window under wxWidgets >= 2.9 to include the system
233  information before the first log message like it does under wxWidgets 2.8.
234
235* cavern: Add support for "*cs JTSK" and "*cs JTSK03".
236
237* tests/: Improve test coverage.
238
[7bd113b]239* Translation updates for many languages, plus the start of translations to
240  Greek and Polish.
[9aa10ad]241
242* Fix to build against wxWidgets 3.0 built with assertions disabled.  Reported
243  by Martin Sluka.
244
245* Fix warnings when compiling with clang (which is the default compiler on
246  Mac OS X).  Reported by Martin Sluka.
247
[44f51ca]248Changes in 1.2.15 (2014-08-14):
249
250* cavern: The *cs command now also supports "long-lat", "s-merc" (for "Web
251  Mercator"), EPSG and ESRI codes, "eur79z30", "ijtsk" and "ijtsk03".  This
252  means that we now support all the coordinates systems which Therion does,
253  except for a few which don't have X=East and Y=North.  The documentation
254  for *cs has also been improved.
255
256* aven: We no longer persist full screen mode between runs - it's not a
257  standard behaviour of desktop programs, and it's too easy to go into full
258  screen mode from the menu and then not be able to get out again because you
259  don't know the required key shortcut. (ticket#39)
260
261* aven: When in full screen mode, moving the mouse to the top of the screen now
262  makes the menu bar appear.  This provides a non-shortcut way out of full
263  screen mode, as well as making it easier to perform other operations while in
264  full screen mode.  The current implementation gives an annoyingly flickery
265  transition, but hopefully we can improve this in future. (ticket#39)
266
267* (MacOS X version): If built with wxWidgets >= 3.1.0 (which is still in
268  development), we now call EnableFullScreenView() which improves the full
269  screen mode experience on OS X 10.7 and later.
270
271* img library: Improve documentation for img_ERROR_INFO.
272
273* tests/: Ship some missing .out files and compare.tst.
274
275* tests/: cavern.tst testcase back2 is now actually used.  Fix a bug in this
276  testcase, and extend it to cover a variant of the situation reported as a bug
277  in therion by Bill Gee to the therion list.
278
279* (Linux version) survex.spec: Add run-time requirement on proj and proj-epsg
280  for the survex package and on tk for the svxedit package.
281
[6a87cce]282Changes in 1.2.14 (2014-07-05):
[5c676e2]283
[1efeb6d]284* img library: Add ability to store a PROJ4 string describing the coordinate
285  system in use in 3d v8 files.
286
287* aven: If the 3d file specifies a coordinate system, then use it for exporting
288  to formats which need to know (currently GPX).  If the input file doesn't
[6a87cce]289  specify the coordinate system, allow the user to enter a PROJ4 string in the
290  export dialog.
[1efeb6d]291
[ea59b58]292* aven: You can now quickly zoom to a particular area by holding down the
293  "Shift" key and dragging with the left mouse button to create a rectangular
294  "rubber band box" around the area you wish to zoom to.  If you release the
295  "Shift" key while still dragging, the box is centred on the start point
296  rather than having one corner there.
297
[26e7fa4]298* aven: Fix exporting of passage tubes in elevations and extended elevations
299  - previously up and down were getting drawn across the page!
300
[5c676e2]301* aven: Fix "Cancel" to work on the print/export dialog, broken by changes in
302  1.2.13.  (Reported by Brian Clipstone)
303
[515b83e]304* aven: Fix the conditions on which the menu item "Cancel measuring line" is
305  enabled - previously it was hard to actually cancel it via the menu.
306  Reported by Hugh St Lawrence.
307
[5c676e2]308* aven: Fix wx assertion failures when showing hit test debug view on platforms
309  such as 64-bit Linux.
310
[2c5ec88]311* aven: When viewing from above, show "Plan" above the "clino" which indicates
312  the tilt angle (instead of "Elevation -90°").
313
[5c676e2]314* aven: The extended font data now loads faster, and also uses less memory on
315  64-bit platforms.
316
[ea59b58]317* aven: Dragging the vertical divider between the side panel and the 3D view
318  now only updates when you finish the drag, as redrawing continuously just
319  looks clunky except on an ultra-fast machine.
320
[2c5ec88]321* aven: (German translation) Abbreviate "Blickrichtung" so it doesn't overfill
322  the space available in the aven UI.
323
[1efeb6d]324* cavern: Add a *cs command to allow setting the coordinate system for *fix
325  commands, and the coordinate system used for processed survey data.  The
326  latter is now stored in 3d v8 format files.
[ea59b58]327
[515b83e]328* cavern: Add support for 'L' flag (exclude from length) in Compass .dat files
329  and handle it in the same way as the "DUPLICATE" flag in .svx files.
330
[6a87cce]331* cavern: If there's more than one *fix command with coordinates, still
332  actually fix the second and subsequent ones, to avoid triggering bogus errors
333  about unconnected surveys.
334
335* cavern: If there's more than one *fix command with coordinates, report the
336  station name of the previous one, plus the file and line number where it was.
337
[67a0fc6]338* cavern: Fix handling of the rather contrived case of *fix with no coordinates
339  followed by *solve and then another *fix with no coordinates not to access
340  freed memory.
341
[1efeb6d]342* dump3d: Report any specified coordinate system.
343
344* doc/3dformat.htm: Update to document how the coordinate system is stored.
345
[2c5ec88]346* (Microsoft Windows version): Include dump3d in the installer.
347
[5c676e2]348* Fix a compiler warning.
349
350* Improve test coverage.
351
[0d365be]352Changes in 1.2.13 (2014-05-15):
[acbb5b1]353
[8ccd1d8]354* aven: Fix --print option to wait for printing to happen before exiting
355  (previously it would exit right after opening the print dialog, so you
356  couldn't actually print anything out using it).
357
[acbb5b1]358* aven: Increase the threshold for how close the pointer needs to be to a
359  station from 5 pixels to 7 to try to help touchscreen users.  Reported by
360  Hugh St Lawrence.
361
[0d365be]362* aven: Add "fat finger" mode, toggled by pressing F2, to allow investigating
[8ccd1d8]363  if increasing the minimum pointer to station threshold helps Hugh's problems
364  with using aven on a touch screen device.
365
[acbb5b1]366* aven: The measuring line was unable to see stations which had just been
367  revealed by toggling surface or underground legs on - this is now fixed.
368
369* aven: Add "hit test grid debug" mode, which shows the hit test grid and how
370  many entries are in each box (toggled by F3).
371
372* aven: Pressing F4 now allows the user to toggle wxWidgets assertion messages
373  off and back on.
374
375* aven: Create the empty hit-test grid data structure lazily, to reduce start
376  up time a little.
377
378* cavern: Improve messages which talk about "tags" and/or "prefixes" in *begin
379  and *end commands to instead talk about "survey names".
380
381* cavern: For ages cavern has warned if you reentered a survey, but this
382  warning was suppressed if it occurred at the same line of the same file as
383  the survey was first entered, but this can only happen if you include the
384  same survey file more than once, which isn't a sensible thing to do for a
385  file with actual survey data in (you might reasonably do it to set up survey
386  grade details or something like that).  The warning is now given in this
387  situation too.
388
389* cavern: After 5 warnings about reentering a survey we give up warning about
390  it, but we used to keep reporting where the survey was originally entered -
391  this secondary diagnostic message is now silenced when the main message is.
392
393* (Microsoft Windows version): Compile C code with optimisation on.
394
395* Add the start of a Russian translation, with messages take from therion.
396
397* Minor translation updates to French.
398
399* Fix compiler warning from GCC.
400
401* Testsuite improvements:
402
403  + Test that "..." anon station works.
404
405  + cavern.tst: Check number of errors returned by all testcases which should
406    fail and give an error count.
407
408  + cavern.tst: Fix to actually fully test everything when builddir != srcdir.
409
[ad727d8]410Changes in 1.2.12 (2014-04-14):
[46d12e9]411
[63e8642]412* aven: Fix measuring line to show change in altitude rather than altitude
413  itself (accidentally broken by changes in 1.2.11).  Reported by Brian
414  Clipstone.
[46d12e9]415
[ad727d8]416* aven: Fix printing when built with wxWidgets 3.0.
417
418* aven: Several visual improvements to printouts:
419
420  + Move the numbers below the scale bar down a little so that they don't
421    overlap the scale bar ticks.
422
423  + Set the clipping region after we draw the page border and info box to avoid
424    clipping the border in print preview.
425
426  + Tidy up the appearance of the compass and elevation arrow.
427
[63e8642]428* aven: Fix to build with libav 10.  Reported by Moritz Muehlenhoff in
429  <http://bugs.debian.org/739332>.
[46d12e9]430
[63e8642]431* aven: Fix to build with older libav where avcodec_free_frame() isn't
432  available.
[46d12e9]433
[ad727d8]434* (Linux version) survex.spec: Update spec file used for building RPM packages.
435
436* (Unix version): Add "Keywords:" entry to .desktop files.
437
438* (Unix version): Enable large file support, mostly to support filing systems
439  which return 64 bit inode values, such as CIFS mounts.
440
[63e8642]441* (Microsoft Windows version): Only allow "A-Z" or "a-z" for driver letters,
442  rather than any character which is a letter in the current locale.
[46d12e9]443
[63e8642]444* Various translation updates.
[46d12e9]445
[aac3336]446Changes in 1.2.11 (2014-01-28):
[fb941bfd]447
448* aven: Fix wxWidgets assertion when double clicking on an anonymous station.
449  Reported by Kevin Dixon.
450
[aac3336]451* aven: Embed the font data for the first 256 Unicode characters for use in the
452  survey pane into the compiled aven binary to reduce start up overhead.  Any
453  additional characters needed are loaded from a data file only if/when a
454  character >= U+100 is actually needed (as before).
455
[ad3017d]456* aven: Fix display of Unicode characters above 256 when there's a character
457  <= 256 earlier in the same string.
458
[77bdacf]459* aven: Use the actual width of Unicode characters above 256 rather than
460  assuming they are 16 pixels wide.
[ad3017d]461
462* aven: If full screen, don't show the side panel when a new file is opened
463  (e.g. via Ctrl+O).
464
465* aven: Don't give an assertion failure when showing passages for a cave with
466  no vertical extent.  Reported by Jonny Prouty.
467
468* aven: Change terminology in print dialog - say "legend" instead of "info
469  box".
470
471* aven: Add option to show the tilt angle as a percentage gradient.
472
473* aven: Show the units (degrees, grads, or percent) for the tilt and bearing
474  indicators.
475
476* aven: All length units are now translatable.
477
[fb941bfd]478* aven: Split log_fl_error helper function out of CHECK_GL_ERROR macro, which
479  will reduce code size and also the number of deprecation warnings about
480  gluErrorString on Mac OS X 10.9.
481
[ad3017d]482* (Microsoft Windows version): aven: Try to work around redraw issues related
483  to the measuring line by redrawing the whole window, which doesn't seem to be
484  measurably slower.
485
486* cavern: If *units is used to try to set units for LEVEL, PLUMB, or POSITION,
487  give an error rather than quietly ignoring the attempt.
488
[77bdacf]489* cad3d: Make cad3d remap control characters and spaces in station names when
490  generating PLT output in the same way aven does.
491
[ad3017d]492* Various translation updates (particular thanks to Eric Madelaine and Dennis
493  Baudys), including the start of a Bulgarian translation, with messages taken
494  from Therion and elsewhere.
495
496* (Microsoft Windows version): On Microsoft Windows 2000 and newer, use
497  GetUserDefaultUILanguage() to get the UI language to use.  For older
498  versions, continue to use GetUserDefaultLCID().
[fb941bfd]499
500* (Microsoft Windows version): The Indonesian translation will now be used
501  automatically when the system language is set to Indonesian.
502
503* (Mac OS X version): Fix to build with wx 3.0.0 on OS X 10.9.  Thanks to David
504  A. Riggs for his work on this.
505
506* (Mac OS X version): Update buildmacosx.sh script to use wx 3.0.0, and add a
507  checksum check for the downloaded wx sources.
508
509* Fix a lot of the compiler warnings when building with clang.
510
[ad3017d]511* doc/manual.sgml: Add missing quantities to the list documented as accepted by
512  *units: LEFT, RIGHT, UP/CEILING, DOWN/FLOOR (missing entirely);
513  BACKCOMPASS/BACKBEARING, BACKCLINO/BACKGRADIENT (missing from the main list,
514  mentioned in list of the units that can be set for them); COUNT (missing
515  alternative name for COUNTER); DX/EASTING, DY/NORTHING, DZ/ALTITUDE
516  (incorrectly listed as X, Y, Z).  Reported by Jonny Prouty.
517
518* Test suite: Improve test coverage for cavern.
519
[0ecf3b1]520Changes in 1.2.10 (2014-01-15):
521
522* aven: Fix assertion if two mouse buttons are held down at the same time.
523  If dragging with more than one mouse button held down, releasing one causes
524  another which is still held down to take effect.  Reported by Brian
525  Clipstone.
526
[53966d3]527* aven: If we fail to start the external editor when the user clicks on an
528  error or warning from cavern, show an error box.
529
[6f0d0d8]530* aven: If the survey has a title, add it as a top-level <title> element to
531  exported SVG files.
532
533* aven: Escape '<', '>', and '&' in labels in exported SVG files.
534
535* aven: In GPX export, set the <time> element to the datestamp from the 3d
536  file.
537
538* aven: Don't try to write the title if it isn't set or is empty when exporting
539  GPX files.
540
541* aven: Don't bother looking up the printer page setup info when exporting.
542
[0ecf3b1]543* (Microsoft Windows version): aven: Fix crash on "File->Print" or
544  "File->Export" under Windows XP, reported by Brian Clipstone.
545
546* (Microsoft Windows version): aven: Fix error dialog about an incorrectly
547  encoded filename which could occur if run without being asked to load a file
548  on startup.
549
550* (Microsoft Windows version): aven: Compile with optimisation on.
551
552* img library, aven: Although processed CMAP data files are often referred to
553  as "CMAP .XYZ files", it seems that actually, the extension .XYZ isn't used,
554  rather .SHT (shot variant, produced by CMAP v16 and later), .UNA (unadjusted)
555  and .ADJ (adjusted) extensions are.  Since we've long checked for .XYZ, we
556  continue to do so in case anyone is relying on it, but also check for the
557  other extensions.
558
559* img library: Add new "datestamp_numeric" field to struct img giving the
560  datestamp as a time_t in UTC (or (time_t)-1 if there's no datestamp or we
561  failed to convert it).  For .3d >= v8, this field is reliable.  We attempt to
562  convert date strings in .3d <= v7 and CMAP XYZ files, but may get the
563  timezone wrong.
564
565* img library: Fix my_strcasecmp() to handle top-bit set characters better.
566
[6f0d0d8]567* cavern: Fix NULL pointer dereference when processing Compass DAT file without
568  'SURVEY DATE:'.
[0ecf3b1]569
[6f0d0d8]570* doc/manual.sgml: Update references to Survex 1.1 which should be to 1.2.
[0ecf3b1]571
[6f0d0d8]572* doc/manual.sgml: Note the station length limit Smaps used.
[0ecf3b1]573
[53966d3]574* Fix some compiler warnings if built with glibc's fortify source feature
575  enabled.
576
[6b6fb4d]577Changes in 1.2.9 (2014-01-08):
578
579* Document --3d-version in cavern man page and the manual.
580
581* aven: Fix compilation error in movie export code with recent libavi.
582
583* aven: Fix warning on stderr when export a movie as MPEG.
584
585* img library: In non-hosted mode, don't define GETC and PUTC if they're
586  already defined, to allow easy overriding with getc_unlocked() and
587  putc_unlocked() (which are significantly faster on Linux).
588
589* img library: In non-hosted mode, check that int is at least 32 bits,
590  and if not, use long.  In practice, platforms with 16 bit int are mostly
591  obsolete, but it's not hard to be portable here.
592
593* img library: Add test that img.c and img.h compile in non-hosted mode
594  (regression test for issue fixed in 1.2.8).
595
596* (Microsoft Windows version): aven is now built with wxWidgets 3.0.0.
597
598* Update translations from launchpad and from existing similar messages.
599
600* Fix some compiler warnings.
601
[e1f27c4]602Changes in 1.2.8 (2013-10-29):
[da65891]603
604* cavern: Fix handling of anonymous wall stations ('..' by default) to
605  implicitly set the SPLAY leg flag, as was intended.  Reported by Thomas
606  Holder.
607
[e1f27c4]608* cavern: Tweak .err file output not to lose the space in front of certain
[034141d]609  statistics when the value gets large.
610
[a4adf09]611* cavern: Eliminate redundant progress message when solving simultaneous
612  equations.
613
[e1f27c4]614* aven: Add a format drop down to the export dialog, and only show fields which
615  are meaningful and supported for the currently selected export format.  The
616  format defaults to that used most recently.  The "Elements" and "View" boxes
617  have been swapped in the print and export dialogs as that layout works much
618  better when the "View" box is hidden.
619
[0056ee1]620* aven: Changing checkboxes in the print or export dialog didn't work in 1.2.7
621  - now works again.  Reported by Anthony Day.
622
[e1f27c4]623* aven: Add GPX export (based on findentrances patch from Olaf Kähler).  In
624  this release the projection which the survey coordinates are in defaults
625  to the BMN M31 grid used in the Totes Gebirge in Austria.  On Unix, you
626  can edit ~/.aven and add a new line setting 'input_projection' to a PROJ
627  projection string.  The ability to specify this projection in a better
628  way is coming soon.
629
630* aven: New export options "Origin in centre" and "Full coordinates" - the
631  latter fixes #10.  GPX and PLT output implicitly force "full coordinates".
632
633* aven: The "Sketch" vector drawing program got renamed to "Skencil" some
634  time ago, so update references.
635
636* aven: Make the Presentation->Play menu item a checkbox, to avoid a warning
637  with wxMSW 2.9.5.  Reported by Brian Clipstone.
638
639* aven: Make right click in an empty presentation mark the current position and
640  open it to edit, instead of crashing.
641
642* aven: Update movie export code to work with latest libav API.  Reported by
643  Sebastian Ramacher.
644
645* aven: Improve reporting of errors during the process of exporting a movie.
646
647* aven: Don't try to close the movie if we aren't producing one.
648
649* aven: Fix assertion failure when double-clicking on the survey with wx2.9.
650
651* aven: Fix to build with wxMSW 2.9.5.
652
653* aven: Fix to build with wx 2.9.5 with wx2.8 compatibility disabled.
654
655* cad3d: The "Sketch" vector drawing program got renamed to "Skencil" some time
656  ago, so add a new --skencil option to specify this output format.  The old
657  name (--sketch) is still recognised for compatibility.
658
659* cad3d: Make --marker-size work for Skencil and SVG output.
660
661* dump3d: Make --show-dates option show dates for XSECT.
[9fc1cac]662
[88b54df6]663* img library:
664
[e1f27c4]665  + Fix to work once more when used outside of Survex (missing definition of
666    max() macro and a bad call to free() in img_close() for a file opened for
667    reading).
668
669  + Use lround() instead of round(), and make the tests around whether we use
670    the library function or the our fallback implementation saner.
671
672  + Fix // comments in C code for portability to pre-C99 compilers which don't
673    support these as an extension.
[88b54df6]674
[f807d8bf]675  + Can now be compiled as C++ as well as as C.
676
[e1f27c4]677* (Microsoft Windows version): The installer is now built with a newer version
678  of Innosetup, and includes translations for all the languages which Survex
679  itself has any translations for.
680
681* (Microsoft Windows version): aven is now built with wxWidgets 2.9.5.
682
683* Minor translation updates.
684
685* tests/Makefile.am: Distribute files for "normal_bad" testcase.
686
[e34bebc]687Changes in 1.2.7 (2013-07-27):
[65d9b6b]688
[e34bebc]689* Add support for anonymous stations, which are indicated by one, two or three
690  separator characters - with the default separator of '.', that means '.',
691  '..', and '...' are anonymous stations.  Single separator ('.' by default)
692  is an anonymous non-wall point, double separator ('..' by default)
693  is an anoymous wall point at the end of an implicit splay), and triple
694  separator ('...' by default) is an anoymous point (with nothing special about
695  the leg).  A new *alias command allows '-' to be mapped to '..' for
696  compatibility with pocket topo: *alias station - ..
[07beaa4]697
[e34bebc]698* New version 8 of the 3d format:
[07beaa4]699
[e34bebc]700  + Supports new flags img_SFLAG_ANON and img_SFLAG_WALL.
[07beaa4]701
[e34bebc]702  + New explicit file-wide flag for 'this is an extended elevation', rather
703    than modifying the survey title to indicate this.
[da9d788]704
[e34bebc]705  + The survey prefix is often unchanged from one leg to the next, so use a
706    spare flag to compactly indicate when there's no label change.
[da9d788]707
[e34bebc]708  + The data style of each leg is now stored.
[da9d788]709
[e34bebc]710  + The "processed at" time is stored as seconds since 1970 rather than a
711    human-readable string.
[da9d788]712
[e34bebc]713  + Since 3d v8 features significant changes to the format, the format
714    documentation for v7 and earlier has been split off into 3dformat-old.htm.
[da9d788]715
[e34bebc]716* img library:
[da9d788]717
[e34bebc]718  + New station flags img_SFLAG_ANON and img_SFLAG_WALL.
[da9d788]719
[e34bebc]720  + Handle .pos files containing unnamed stations - don't suck the next line in
721    as the station name, and set img_SFLAG_ANON for them.
[da9d788]722
[e34bebc]723  + Repurpose the long unused fBinary parameter to img_open_write() as a flags
724    parameter, and add img_FFLAG_EXTENDED to specify that this is an extended
725    elevation, in place of appending " (extended)" to the title.  Internally we
726    still append this to the title (and remove it upon reading) when writing
727    3d v7 or earlier, but for the new 3d v8 format, this flag is stored
728    explicitly in the file.
[da9d788]729
[e34bebc]730  + img.h: Add comments for the lists of "Leg flags" and "Station flags".
[da9d788]731
[e34bebc]732* aven:
[da9d788]733
[e34bebc]734  + We now require at least wxWidgets 2.8.0 - it was released over 6 years ago
735    now, and the wx developers consider even 2.8 to be rather long in the
736    tooth.  We stopped testing building with wxWidgets 2.6 some time ago, and
737    formally dropping support for older versions allows a number of workarounds
738    to be removed from the aven source code.  Also, features deprecated in
739    wxWidgets 2.9 are no longer used in our code.
[da9d788]740
[e34bebc]741  + Don't run incremental search on every key-press, as on a slow machine the
742    short initial search(es) will take a while but not be useful.  Instead only
743    actually run the search when we're told there are no more key-presses
744    queued up.
[da9d788]745
[e34bebc]746  + Implement support for including cross-section information in exported SVG
747    and DXF files (ticket#4).  The DXF export is untested currently.
748
749  + Show splay legs faded by default, with menu options to hide them or show
750    them like other legs.
751
752  + Speed up loading a .3d file with cross-sections by using a map to convert
753    station names to positions.
754
755  + In the cavern log window, don't highlight a file:linenumber if there's no
756    message after it, which avoids highlighting the "Included from" lines
757    wrongly.
758
759  + Fix not to crash when trying to report an error while starting up.
760
761  + (MacOS X version): Change the menu shortcut for "Full Screen Mode" to be
762    the OS X standard shortcut Shift-Command-F (previously we used F11, but
763    that's used by the desktop).
764
765  + Add checks for errors when reading the font file.
[07beaa4]766
[e34bebc]767  + Remove useless extra quoting when invoking vim to show the location of an
768    error from cavern.
[07beaa4]769
[e34bebc]770  + Include GL/gl.h before GL/glext.h (needed on Debian wheezy).
[da9d788]771
[e34bebc]772  + Use wxValidator to simplify keeping svxPrintDlg member variables and fields
773    in the dialog in sync.
[da9d788]774
[e34bebc]775* cavern:
[3dfffa2]776
[e34bebc]777  + Demote errors about invalid dates to warnings, since we've accepted *date
778    for ages without any checks on the value, and so existing datasets
779    probably contain invalid dates and dates in other formats.  (ticket#19)
[3dfffa2]780
[e34bebc]781  + New *alias command allows '-' to be mapped to '..' for compatibility with
782    pocket topo: *alias station - ..
[07beaa4]783
[e34bebc]784  + We want to warn if there's a clino reading which it would be impossible to
785    have read from the instrument (e.g. on a -90 to 90 degree scale you can't
786    read "93" (it's probably a typo e.g. for "39").  However, the gradient
787    reading from a topofil is typically in the range 0 to 180, with 90 being
788    horizontal.  Really we should allow the valid range to be explicitly
789    specified, but for now we infer it from the zero error - if this is within
790    45 degrees of 90 then we assume the instrument can read between 0 and 180
791    degrees.
[da9d788]792
[e34bebc]793  + If the survey isn't all connected, still run survey tree checks and report
794    errors and/or warnings which might suggest typo locations.  Thanks to Kevin
795    Dixon for the report which highlighted this issue.
[da9d788]796
[e34bebc]797  + Report a warning if *begin SURVEY has a separator character in SURVEY.
[da9d788]798
[e34bebc]799  + Report column numbers as well as line numbers for some cavern errors and
800    warnings.
[07beaa4]801
[e34bebc]802  + Adjust width of node stats table to fit longest count when there are more
803    than 9999 of a particular order of node.
[07beaa4]804
[e34bebc]805  + If the argument to *include has an opening double quote but the closing
806    double quote is missing, then skip trying to open the file.
[da9d788]807
[e34bebc]808  + Move "Station X referred to just once" warning after non-existent survey
809    check - if both fire, the non-existent survey error is likely to be more
810    relevant.
[da9d788]811
[e34bebc]812  + We no longer follow an error for a bad reading in passage data with a bogus
813    "End of line not blank" error, but instead check the remaining readings on
814    the same line.
[da9d788]815
[e34bebc]816  + We no longer follow an error about OMIT for a required reading with a bogus
817    "End of line not blank" error.
[7f6250a]818
[e34bebc]819  + Report an error if the scale factor in *calibrate is zero - it doesn't make
820    sense and probably means someone reversed the arguments to *calibrate.
[3dfffa2]821
[e34bebc]822  + Report the parent include files starting from the outermost, as that's more
823    logical when there are multiple levels involved.
[07beaa4]824
[e34bebc]825  + If we were expecting a numeric field and instead get something which starts
826    with '+', '-', or '.' but which isn't a number, then fix the error to
827    include that character in the token reported.
[3dfffa2]828
[e34bebc]829  + Simplify handling of quantity lists to only recognise 'DEFAULT' as the
830    first item.
[07beaa4]831
[e34bebc]832* cad3d: Check for errors from img_rewind() and report them.
[07beaa4]833
[e34bebc]834* dump3d:
[07beaa4]835
[e34bebc]836  + Build, install and package dump3d as standard - it's useful for grabbing
837    info from 3d files in scripts.
[07beaa4]838
[e34bebc]839  + Add --show-dates option.
[07beaa4]840
[e34bebc]841  + Show only 2 decimal places on coordinates and passage dimensions.
[07beaa4]842
[e34bebc]843  + Report the data style of legs.
[da9d788]844
[e34bebc]845  + Report if the file is an extended elevation.
846
847  + Report img_STOP as STOP rather than CODE_0xffffffff.
[3dfffa2]848
849* Test suite:
850
851  + cavern.tst: Fix equatenosuchstn testcase (added in 1.2.6) to normalise the
852    expected output so it passes reliably.
853
[e34bebc]854  + cavern.tst: Run diffpos <expected> <actual> so the reports of 'Added' and
855    'Deleted' stations upon failure are the more natural way round.
856
[07beaa4]857  + Add more testcases, expand some existing testcases, and add expected output
858    for more.
859
[e34bebc]860* (Microsoft Windows version): Use wx-config's --cc and --cxx flags to find the
861  appropriate C and C++ compilers to use, and link mingw build statically to
862  avoid needing the libgcc DLL (which newer GCC seems to have by default).
[3dfffa2]863
864* (Unix version): When determining the character set for command-line tools,
865  check environmental variable LANG after LC_ALL and LC_CTYPE.
866
867* When determining the language, check environmental variable LC_ALL before
868  LC_MESSAGES and LANG (but after SURVEXLANG).
869
[e34bebc]870* If we don't find the message file, only give an error if it was specified
[665183c]871  with SURVEXLANG, since that is an explicit instruction to Survex, whereas
[e34bebc]872  LANG, LC_ALL and LC_MESSAGES are essentially system "preferred locale"
873  settings.
874
875* There are a handful of hard-coded English message strings for reporting
876  errors trying loading message files, etc.  These are all now ASCII, as if we
877  fail trying to open a message file, it's more likely the encoding isn't
878  set correctly.
879
880* Prune strings we are no longer using and are probably unlikely to use again
881  into a new file po_codes_dead, so that translators don't get presented with
882  them to translate.
883
[07beaa4]884* Merge lots of translation updates.  Most translations are now complete or
885  close to complete.
[3dfffa2]886
887* Add start of Indonesian translation from Arief Setiadi Wibowo.
888
[07beaa4]889* Fix various compiler warnings when building from source.
890
[e34bebc]891* Include scripts gdtconvert and gen_img2aven in the source distribution.
892
[c575465]893Changes in 1.2.6 (2012-02-23):
[b081031]894
895* (Mac OS X version): Fix so that cavern finds its messages when run by aven.
896
897* (Microsoft Windows version): Include JPEG images for aven in the installer
898  package (ticket#35).
899
900* cavern: If we have a reference to a station in a non-existent survey, give a
901  helpful error rather than saying the station hasn't been exported from the
902  survey.  (Bug reported by Martin Green via email)
903
904* aven: Fix to build with a non-Unicode wxWidgets library.  Patch from Olaf
905  Kahler.
906
907* findentrances: Add findentrances utility from Olaf Kahler which produces a
[c575465]908  .gpx file with waypoints for entrances.  This needs libproj so is disabled
909  by default for this release - to enable it install the development stuff for
910  libproj and build survex with:
911
912      make FINDENTRANCES=findentrances
913      make install FINDENTRANCES=findentrances
[b081031]914
915* dump3d: Add support for showing img_ERROR_INFO items.
916
917* doc/3dformat.htm: Merge in some improvements from Mike McCombe.
918
919* Incorporate a French translation from launchpad I'd previously copied the
920  English version of by mistake.  Attempt to correct mistranslation of "survey
921  file".
922
[685116f]923Changes in 1.2.5 (2012-01-03):
924
925* aven:
926
927  + The survey tree in the left panel is now in sorted order once more.
928
929  + No longer fails with an assertion if used for a long time (we were leaking
930    an OpenGL list each time one had to be regenerated).
931
932  + Now builds with newer FFmpeg library.
933
934  + Draw measuring line in front of the indicators rather than behind them.
935
936  + Loading a new file (or reloading the current one) no longer invalidates
937    the OpenGL lists for the compass and clino, so will be a fraction faster.
938
939* Improve handling of attempts to look up translated messages before the
940  message subsystem is fully initialised (which only happens if there's an
941  error early on).
942
943* Improve the survex(7) man page text, and fix it to be marked as section 7 in
944  the man page source as well as in the filename.
945
[f15ca67f]946Changes in 1.2.4 (2012-01-01):
947
948* aven:
949
950  + A change in 1.2.3 meant that aven tried to use OpenGL before it was
951    initialised, which doesn't cause problems in some machines, but causes aven
952    to abort on others.  This is now fixed, and there's a check in place to
953    help avoid similar issues in future. (ticket#34)
954
955  + Always use metres or feet for the depth colour key, and chose a consistent
956    precision by looking at the depth range. (ticket#30)
957
958  + Show the depth units below the colour bar rather than after every value.
959
960  + When zooming way in, stay in metres rather than switching to cm.
961
962  + On the scale bar, say “1 mile” rather than “1 miles”.
963
964* Translation updates for Catalan, French and Slovak.
965
[5b9942e]966Changes in 1.2.3 (2011-12-31):
967
968* Fix to build with wxWidgets 2.9.2.
969
970* (Mac OS X version):
971
972  + Processing .svx files from aven now works.
973
974  + Remove spurious blank lines from the licence text in "Get Info".
975
976  + Don't create the help menu at all, as it is empty (because the "About"
977    entry goes elsewhere) and sometimes seems to appear in the UI.
978
979  + INSTALL.OSX: Update to reflect current status.
980
981* aven:
982
983  + Fix Y coordinates of surface surveys on printouts.  (Closes #32)
984
985  + Improvements to text plotted on the survey pane:
986
987    - Support plotting Unicode character points > 256 by lazily loading the
988      data for them from the font file and plotting them with a direct call to
989      glBitmap(), which is slower but doesn't require a display list per
990      character.
991
992    - Adjust the spacing from fixed width to putting a one pixel gap either
993      side of each one character (so two between adjacent glyphs).  Mostly this
994      reduces the horizontal width, but it adds a pixel for characters like "m"
995      and two in a few cases.
996
997    - Fix .pixelfont file generation to correctly handle characters wider than
998      8 pixels.
999
1000  + Fix expected cross shape so don't always reject using texture mapping to
1001    draw crosses.
1002
[3ea0178]1003  + As we read a survey file, eliminate tubes consisting of zero XSECTs as well
1004    as those consisting of just one.  Previously we would trip over the empty
1005    tube later.  Such tubes can for example be created by extend if a splay shot
1006    is the start or end of a tube.
1007
[5b9942e]1008  + Make the green colour used for entrances in the survey tree the same
1009    (slightly darker than before) green used for the entrance blobs.
1010
1011  + Report the version of the library we're actually running with if built
1012    against wx >= 2.9.2.  Make it clear that the version reported is the
1013    version *built* with for wx < 2.9.2.
1014
[3ea0178]1015* extend:
1016
1017  + Copy the end markers for passage tubes.
[5b9942e]1018
[3ea0178]1019  + Preserve left and right data for tubes (previously they were set to -1.0
1020    which means "no info").
1021
1022* img library: Fix incorrect comment in img.h which claimed that img_XFLAG_END
1023  was no longer used - it certainly is!
1024
1025* Use curly double quotes instead of "`" and "'" to quote filenames, etc in
1026  messages, and curly single right quote instead of straight ASCII apostrophe.
1027  Fall back to using straight ASCII versions if we can't represent them in the
1028  current character set.
[5b9942e]1029
[3ea0178]1030* Translation updates for Catalan, French, Slovak and Spanish.
[5b9942e]1031
1032* Test suite:
1033
1034  + Add test coverage for interleaved diving data.
1035
1036  + Add testcase for diving data with topofil-style distance.
1037
[94960ad]1038Changes in 1.2.2 (2011-10-06):
1039
1040* aven:
1041
1042  + Replace the textured-mapped font drawing with an approach based on
1043    glBitmap.  This doesn't suffer from the character alignment issues which
1044    the textured-mapped fonts had, and is actually significantly faster on some
1045    machines.  The current font used is (mostly) fixed-width, but this isn't an
1046    inherent limitation - it was just the easiest font data to convert to a
1047    usable format.
1048
1049  + Fix assertion failure due to rounding differences on loading certain .3d
1050    files.  (ticket#26)
1051
1052  + Fix assertion failure when turning on 3D passages if they stick out higher
1053    or lower than any station.  (ticket#29)
1054
[53f8a93]1055  + Fix grid not to disappear when blobs are turned on and blobs are drawn
1056    using lines.
1057
[94960ad]1058  + If a degree sign isn't available in the character set in use, transliterate
1059    it to 'dg' rather than skipping it.
1060
1061  + Fix message which should have been a degree sign but got lost in the format
1062    change for 1.2.0 and then got reassigned in 1.2.1.  Externally, this means
1063    that bearings in the status bar now have a degree sign after them if they
1064    are in degrees rather than nothing (1.2.0) or "&Hide Compass" (1.2.1).
1065
1066  + Fix print dialog to calculate the scale required for "One page" right
1067    before it calculates how many pages are required, so we don't end up
1068    something other than 1x1 being shown when the user changes settings.
1069
1070  + Update the calculations for picking a scale and for deciding how many
1071    pages are needed to take into account the change in info box height made
1072    in 1.2.1.
1073
[9704252]1074Changes in 1.2.1 (2011-10-04):
[e3c58c3]1075
1076* Translation updates for US English.
1077
1078* aven:
1079
1080  + Rename the "depth bar" to "colour key" in documentation, menus, etc since
1081    it now shows colours for dates and errors as well as depths.
1082
1083  + In the colour key for "colour by date", change "No info" to "Undated".
1084
1085  + Remove the dark grey background from the colour key and just put a single
1086    pixel black border around the colours.  This is more in keeping with the
1087    other controls, and means the colours are now on a black background so more
1088    visually similar to the survey legs.
1089
1090  + Move the colour key's "Undated"/"Not in loop" entry down a little to
1091    improve the appearance.  Make each section a pixel taller.
1092
[9704252]1093  + Allow "Colour by X" to be selected even if there's no data for X or only a
1094    single value of X used (the colour key is much smaller in these cases, and
1095    does still provide some useful information).
1096
1097  + Fix incorrect calculation of depth colouring for survey legs which straddle
1098    a depth band boundary.
[e3c58c3]1099
1100  + The scale bar, compass, clino, and colour key now all have right click
[9704252]1101    menus which allow related actions to be performed (especially handy in
1102    full-screen mode).
[e3c58c3]1103
1104  + Improve the font used on the survey pane - it now contains the '-'
1105    character (so the clino now shows negative angles as negative, and dates
1106    in the colour key are now hyphenated).  Also the spacing and alignment
1107    are a little better, though still not perfect.
1108
1109  + PLT file export now handles spaces and control characters in station names
1110    by escaping them with '%' as in URLs.
1111
1112  + Pressing "Enter" on a station in the tree control now centres the view on
1113    that station.
1114
1115  + The scale bar is now cached in an OpenGL display list since it often gets
1116    redrawn exactly the same - for example, when rotating, panning, etc.
1117
1118  + Pressing "F5" forces all cached OpenGL drawing lists to be invalidated and
1119    then forces a refresh of the survey pane.  This is intended as a debugging
1120    aid - if pressing F5 changes the display at all then there's a missing case
[9704252]1121    where a list should have been invalidated (please report if you find such
1122    a case as it is a bug).
[e3c58c3]1123
[9704252]1124  + We now automatically track which OpenGL display lists need to be
1125    invalidated on window width or height changes.
[e3c58c3]1126
1127  + Increase scale bar maximum width from 65% of the window width to 75% as it
1128    was in 1.0.x (except that if that would overlap the clino we now reduce
1129    that proportion down until it reaches 50%).  Make the limit of zooming in
1130    the same as in 1.0.x.  (ticket#23)
1131
[9704252]1132  + (Linux version): Previously wxGTK didn't really handle showing a dialog if
1133    the application was fullscreen (the dialog got opened under the main
1134    window!)  To work around this, aven would switch out of full screen mode
1135    temporarily while showing a dialog.  This case works properly with recent
1136    wxGTK, so disable our workaround with versions we know work.  Also, apply
1137    the workaround only for wxGTK, not everywhere except on Microsoft Windows
1138    as there's no reason to think we need it for other platforms.
[e3c58c3]1139
1140  + Grey out the "View North" action when we're already viewing North, and
1141    similarly for other compass points.
1142
1143  + (Mac OS X and Microsoft Windows versions): Fix missing newline to OpenGL
1144    info in the "About" dialog.
1145
1146  + Fix to set the correct filename on the root of the survey tree - previously
1147    the filename of the previous file loaded was used!
1148
1149  + The movie export code now works with newer versions of the FFmpeg libraries
1150    as well as still working with older versions.
1151
1152  + Fix mixed up messages - the print dialog now says "View" on the left
1153    subgroup of controls rather than some unrelated message.
1154
1155  + On printouts, combine the "Plan View"/"Elevation" info box field with the
1156    field which gives the bearing and reduce the height on the info box by the
1157    removed field, so it's now 3cm for plans and elevations, as for extended
1158    elevations.  Report the tilt angle for tilted elevations which it seems has
1159    been missing for ages (it's not in recent 1.0.x either).
1160
1161  + Tweak the exact positioning of informational text on printouts to look
1162    nicer and make better use of the available space.
1163
1164  + Add keyboard mnemonics to the "Plan" and "Elevation" buttons in the print
1165    dialog.
1166
1167  + Make the sign of the tilt angle for printouts consistent with the sign
1168    shown by the "clino" in the survey pane.
1169
1170  + In the "Print" dialog, when in plan view disable the "Plan view" button,
1171    and similarly for the "Elevation" button.
1172
[9704252]1173  + (Microsoft Windows version): Sort out appearance of custom cursors.
1174
[e3c58c3]1175  + If a label isn't valid UTF-8 or CP1252, fall back to ISO8859-1.
1176
1177  + (Mac OS X version): F11 puts aven into full screen mode, but apparently
1178    you can't get out again easily, so add code to explicitly check for F11
1179    being pressed and toggle full screen.
1180
1181* (Linux version): Fix the RPM .spec file for where man pages now get installed
1182  and package aven.svg and the vim support files.  (Fixes from James Begley)
1183
1184* "make check" now performs several checks on the translation files.
1185
1186* More messages are now available to be translated.
1187
1188* cavern: Fix reporting of ranges of survey coordinates, which was broken by
1189  the message handling changes in 1.2.0.
1190
1191* Fix warning when compiling with GCC.
1192
1193* INSTALL: Mention building wxWidgets with --enable-unicode.  Mention using
1194  sudo for installing on Unix.
1195
1196* In the manual, replace the instructions for building from source with a
1197  pointer to the clearer instructions in INSTALL.
1198
1199* In the manual, make it clear that installing with administrator rights
1200  also applies to newer platforms than XP.
1201
1202* doc/TODO.htm: Update.
1203
[120c1c6]1204Changes in 1.2.0 (2011-09-20):
[b4ac7007]1205
1206* Translation updates for Catalan, French, Romanian, Spanish, Slovak, and US
1207  English.
1208
[9cfcb3f]1209* tests/smoke.tst: aven no longer requires an X display for --help or
1210  --version, so replace skip of this check with a check that this remains the
1211  case.
1212
1213* We now use the standard .po and .pot file formats for storing translations
1214  (rather than the Survex-specific messages.txt format), and then translate
1215  these into Survex's .msg format.
1216
[b4ac7007]1217* (Unix version): Move survex man page to section 7 (since it isn't documenting
1218  an actual command).
1219
[9cfcb3f]1220* (Unix version): Write each generated man page to a temporary file, then
1221  atomically rename, to avoid leaving an empty or partial man page behind if
1222  docbook-to-man dies (1.1.16 had an empty cad3d.1, and we want to avoid a
1223  recurrence of that).
1224
[b4ac7007]1225* (Unix version): Default to installing docs into /usr/share/doc/survex rather
1226  than /usr/doc/survex.
1227
1228* aven:
1229
[120c1c6]1230  + Fix handling of accented characters in the survey pane.
1231
[9cfcb3f]1232  + Aven icon redrawn in SVG format - it's now a vector image which looks
1233    nicer at larger sizes.
1234
[b4ac7007]1235  + Explicitly request double-buffering, which seems to be needed for systems
1236    with GLX >= 1.3.
1237
1238  + Fix crash while trying to load certain .3d files.
1239
1240  + Movie export code updated to work with more recent versions of FFmpeg.
[4095cc0]1241    Currently this is disabled in Microsoft Windows builds, pending getting the
1242    required libraries set up for building releases.
[b4ac7007]1243
1244  + Reporting of errors during movie export improved.
1245
1246  + Force playback speed to "x1" during movie export.
1247
1248  + Use stock IDs for buttons where appropriate - such buttons may now be
1249    rendered with icons on some platforms.
1250
[9cfcb3f]1251  + If a label isn't valid UTF-8, treat it as CP1252 (the Microsoft superset of
1252    ISO8859-1).
1253
1254  + (Unix version): Remove special handling for toggling "full screen" on wxGTK
1255    as it's no longer required with modern versions.
1256
1257  + Don't redraw the survey on every mouse movement in the survey pane unless
1258    the measuring line is (or just was) active.  (ticket #17)
1259
[b4ac7007]1260* cavern:
1261
1262  + Drop "non-fatal" from the report of how many errors there were at the end
1263    of the run - it just confuses users - we won't even get here if there's a
1264    fatal error!
1265
[9cfcb3f]1266  + Add --3d-version option to allow the user to specify the version of the 3d
1267    format to output.  (ticket#21)
1268
1269* img library:
1270
1271  + Make the highest and lowest valid values for img_output_version available
1272    in img.h as IMG_VERSION_MIN and IMG_VERSION_MAX.
1273
[b4ac7007]1274* (Mac OS X version): Fix buildmacosx.sh script to check where the temporary
[120c1c6]1275  volume actually gets mounted.  Fix URL for downloading wxWidgets.
[b4ac7007]1276
[8f9b0b6d]1277Changes in 1.1.16 (2011-05-16):
[ecdb631]1278
1279* Translation updates for German, Spanish, Italian, Portuguese, Brazilian
1280  Portuguese, and US English.
1281
1282* Use horizontal ellipses character rather than '...' and right arrow character
[ec8fd0d]1283  rather than '->' where these characters are available.
[ecdb631]1284
1285* (Unix version): Link with -lGL, if it exists, to support linking with gold or
1286  GNU ld --as-needed (Debian bug #615781).
1287
1288* img.c:
1289
1290  + Fix code typo for IMG_API_VERSION == 0 case.
1291
1292  + Fix code typo in code used when IMG_HOSTED isn't defined.
1293
1294* doc/TODO.htm: Remove entries which have now been done.
1295
[8f9b0b6d]1296* (Microsoft Windows version): aven: We now include all the available
1297  translations for messages from wxWidgets, which means that standard widgets
1298  will appear translated where available even if Survex messages aren't
1299  translated.
1300
[f5e3521]1301Changes in 1.1.15 (2010-10-15):
[2d16e4e]1302
1303* aven:
1304
1305  + In the cavern log window, change the "Rerun" button to "Reprocess" to
1306    follow terminology in manual and elsewhere.  Fixes ticket#15.
1307
1308  + When displaying output from cavern, don't update the window after every
1309    line, but only when we don't have data from cavern pending.  Hopefully
1310    addresses ticket#12.
1311
1312  + If we aren't using GL_POINTS for blobs, draw them using a series of
1313    abutting lines rather than with gluDisk which is faster and gives a
1314    consistent shape.
1315
1316  + Check whether blobs and crosses actually render correctly as points/point
1317    sprites, and if they don't, fall back to drawing them with lines.  The
1318    best method is cached on disk, and rechecked automatically if the graphics
1319    hardware is changed or the drivers upgraded.
1320
1321  + Fix non-USE_FNT case to work again (it's limited to ISO-8859-1 characters
1322    though, so we still enable USE_FNT by default).
1323
1324  + Don't offer "All files" wildcard in presentation save dialog.
1325
1326  + (Microsoft Windows): Handle filenames with non-Latin1 characters in in
1327    more places.
1328
1329  + (Microsoft Windows): Quote filenames with spaces and metacharacters in
[f5e3521]1330    when running cavern from aven.  Fixes ticket#11.
1331
1332* editwrap: (Microsoft Windows): Handle filenames with non-Latin1 characters.
1333
1334* diffpos: Handle files with duplicate labels in better - extend generates
1335  duplicate labels when it breaks a loop.
1336
1337* Enable eswap-break testcase now that diffpos handles duplicate station names.
[2d16e4e]1338
1339* New v7 of .3d format which stores survey dates as number of days since
1340  January 1st 1900, so we now support dates from 1900-2078 (rather than
1341  1970-2037) with a smaller file size.  The img API is now versioned - you
1342  can select the new "version 1" by compiling with -DIMG_API_VERSION=1, which
1343  gives the survey dates in days in days1 and days2 instead of as time_t
1344  values in date1 and date2.  Fixes ticket#14.
1345
1346* Consistently use http://survex.com/ rather than http://www.survex.com/ - the
1347  former has been the canonical name for some time, with www.survex.com just
1348  redirecting to it.
1349
1350* (Unix version): Use unlocked file I/O if available, which can be much faster
1351  in some cases (we don't need the locking as we don't do multithreaded file
1352  I/O).
1353
1354* (Mac version): Fix compilation failure due to clash with Point in Mac OS X
1355  headers.
1356
1357* (Mac version): buildmacosx.sh now works again.
1358
1359* Most tests weren't actually running any testcases (looks like a sh
1360  portability issue).  This is now fixed, and fortunately all tests still pass.
1361
1362* Include the extra .isl translation files for Innosetup in the source archive.
1363
[f9473ab]1364Changes in 1.1.14 (2010-07-26):
1365
1366* Restore compatibility with wxWidgets 2.6 (1.1.13 required wxWidgets 2.8).
1367
1368* aven:
1369
1370  + After processing survey data, if there were warnings or errors, add a
1371    "Rerun" button to allow easy reprocessing after fixing problems.  If there
1372    were only warnings, also add an "OK" button to allow moving on to viewing
1373    the processed survey data (fixes ticket#13).
1374
1375  + Optimise updating of the cavern log window (hopefully fixes ticket#12).
1376
1377  + Fix links in cavern log window to link from exactly '<file>:<line>' (and
1378    not the ': ' after), and to make the title for the terminal the
1379    warning/error message.  Avoid false positives by checking that '<line>' is
1380    a number.
1381
1382  + Don't double escape the contents of href and target in links in the cavern
1383    log window.
1384
1385  + Improve handling of the splitter window, fixing behavioural glitches in
1386    various cases.
1387
1388  + Highlight stations matching any current search when a file is loaded.
1389    (ticket#9)
1390
1391  + (Mac version): Fix build issue due to Mac OS X polluting the global
1392    namespace with its own "Point" class.
1393
1394  + (Unix version): The Gnome print dialog has its own preview window so
1395    suppress ours if using the Gnome one.
1396
1397  + (Unix version): Link aven with -lGLU which SuSE Linux needs.
1398
1399  + (Microsoft Windows version): Fix handling of a double-click on the survey
1400    tree when built with wxWidgets >= 2.8.11.
1401
1402* cavern: Report relevant file and line number for three warnings which didn't
1403  give them before.
1404
1405* (Unix and Mac versions): configure: Update the wx-config probing code -
1406  wxmac-config etc aren't present with newer wxWidgets versions so there's no
1407  point looking for them now.
1408
1409* (Mac version): buildmacosx.sh: This script builds a diskimage with Survex in
1410  for easy installation.  Update it to work with the latest Survex versions
1411  (use WX_CONFIG not WXCONFIG; use a Unicode build of wxWidgets; if building a
1412  private wxWidgets, use 2.8.11 not 2.7.0-1).
1413
1414* manual:
1415
1416  + Correctly capitalise "GTK".
1417
1418  + Note that on Linux we only regularly test builds with the GTK+ version
1419    (change taken from 1.0).
1420
1421* Fixed the cad3d man page, which was an empty file in 1.1.13.
1422
[0bd49eb]1423Changes in 1.1.13 (2010-06-16):
[90d0d71]1424
1425* Say "wxWidgets" instead of "wxWindows" consistently.
1426
[739b92c]1427* img.c: Fix small memory leak (filename_opened member).
[90d0d71]1428
1429* cad3d, aven: Fix export to SVG when a label contains a '%' character.
[f1cbf74]1430
1431* aven:
1432
[90d0d71]1433  + wxWidgets 2.6.0 or newer is now required.
1434
1435  + A "Unicode" build of wxWidgets is now supported.  An "ANSI" build may still
1436    work but hasn't been tested recently (all packaged versions of wxWidgets
1437    seem to be Unicode now).
1438
1439  + Fix potential uses of uninitialised variables which may have been causing
1440    occasional glitches when loading a file on start-up.
1441
[e4bfd2f]1442  + Improvements to the handling of the font used for plotting labels and other
1443    text on the survey pane:
1444
1445    - Loading the font file is more efficient.
1446
1447    - Character spacing is improved.
1448
1449    - Default font is now anti-aliased.
[90d0d71]1450
1451  + "About" dialog:
1452
1453    - Add "Copy" button to copy the system info to the clipboard for easier
1454      bug reporting.
1455
1456    - List OpenGL extensions last, since there are usually lots of them with a
1457      modern gfx card.
1458
1459    - Fix 100% CPU usage while the "About" dialog is open.
1460
1461  + Processing .svx files:
1462
1463    - Passing a .svx file on the command line now works better.
[1324d6c]1464
[739b92c]1465    - Put the survey data log window in a splitter in the usual frame rather
1466      than opening a separate frame for it.
1467
[90d0d71]1468    - Auto-scroll the log window until we've reported a warning or error.
1469
1470    - Fix small memory leak.
1471
1472  + The presentation filename now defaults to using the basename of the
1473    currently loaded dataset, but we always prompt before we first save with
1474    such a name.
1475
1476  + Reduce memory usage when saving a screenshot.
1477
[e4bfd2f]1478  + Allow "Toggle Fullscreen" to work even if no survey is loaded now that we
1479    persist the window size (and maximised or fullscreen state) between
1480    invocations.
1481
[90d0d71]1482  + Fix reporting of OpenGL errors.
1483
1484  + Fix glitches when tilting while looking East.
1485
[739b92c]1486  + Added Portuguese and Slovak translations of wxWidgets messages.
1487
[90d0d71]1488* Documentation:
1489
[e4bfd2f]1490  + Rationalise manual formats - replace PostScript with PDF and drop RTF.
1491
1492  + Drop the "alternative manual formats" self-extracting zip file - people
1493    will generally just want one of the formats, so downloading several
1494    together isn't very useful.
1495
[90d0d71]1496  + 3dformat.htm: Update for v6 format (thanks to Mike McCombe).
1497
1498  + GPL.htm: Replace HTML version of licence with a link to the version on
1499    the FSF website.
1500
1501  + ChngeLog.htm: Stop generating an HTML version of the ChangeLog - it's too
1502    low level to be of interest to non-developers, and developers can look at
1503    the source code.
1504
1505* (Unix version): configure: New preferred name for specifying wx-config script
1506  is WX_CONFIG.  WXCONFIG still supported for compatibility.
[f1cbf74]1507
[e4bfd2f]1508* (Linux version): Source RPM package dropped as you can just build an RPM
1509  package from the source tarball.
1510
[739b92c]1511* (Microsoft Windows version): The installer is now created with a newer
1512  version of InnoSetup, which gives a 10% smaller download.
1513
[2e12f8c]1514Changes in 1.1.12 (2007-02-07):
[5940815]1515
1516* aven:
1517
[3db0798]1518  + Remember the window size or maximised/fullscreen state between invocations.
1519
[5940815]1520  + Add options dialog to "Export" similar to the one for "Print".
1521
[6b2113d]1522  + The "number of pages required" in the print dialog now updates when you
1523    change what is to be shown (underground legs/surface legs/station
1524    names/crosses).
1525
[920b066]1526Changes in 1.1.11 (2006-11-25):
1527
1528* Updated Czech, Spanish, and Slovak translations.
1529
[99d8798]1530* (MacOS X version): Assorted OS X specific tweaks and fixes.
1531
[920b066]1532* aven:
[78c67a6]1533
[920b066]1534  + Pick a smaller and clearer font for labels.
[99d8798]1535
[920b066]1536  + Fix character spacing.
[99d8798]1537
[920b066]1538  + Tweak display of bearing and elevation angles to look nicer with
1539    proportional fonts.
[99d8798]1540
[920b066]1541  + Use the title from the 3d (or plt, etc) file for the window title
1542    rather than the filename.
[99d8798]1543
[920b066]1544  + Show distances to 2 decimal places rather than the nearest integer.
[99d8798]1545
[920b066]1546  + Only consider underground legs when calculating the depth bands and
1547    depth colouring.
[99d8798]1548
[920b066]1549  + Add "Colour by Error".
[99d8798]1550
[920b066]1551  + Add entry for "white" in date and error keys.
[99d8798]1552
[920b066]1553  + When setting the view to a single point, don't change the scale.
[99d8798]1554
[920b066]1555  + If reloading the same file, don't change the view
[99d8798]1556
[920b066]1557  + Fix filetypes selector in open dialog.
[99d8798]1558
[920b066]1559  + Fix the charset we use for aven in certain cases.
[99d8798]1560
[920b066]1561  + Call msg_init before using msg_lang or it won't ever be set!
[99d8798]1562
[920b066]1563  + Pass wx the full language code to initialise the C library locale.
[99d8798]1564
[920b066]1565  + Fix bug in generating prefix tree view which could lead to a bogus
1566    leading dot on some survey names (bug probably introduced in 1.1.10).
[99d8798]1567
[920b066]1568  + "New Presentation" now ensures that the side panel is open
[99d8798]1569
[920b066]1570  + Fix updating of cached opengl lists when the view is reset to the
1571    default.
[99d8798]1572
[920b066]1573* Ignore LANG if it starts with a digit to avoid problems with bogus value for
1574  LANG which AutoCAD installation seems to set on MS Windows.
[99d8798]1575
[920b066]1576* (Unix version): configure: Allow SGMLTOOLS and DOCBOOK_TO_MAN to be
1577  specified.  Either/both can be set to ":".
[99d8798]1578
[920b066]1579* dump3d: Report unknown (to dump3d) codes returned by img.
[99d8798]1580
[920b066]1581* img library: Flag all stations as underground in the old "ASCII" .3d format.
[99d8798]1582
[920b066]1583Changes in 1.1.10 (2006-07-14):
[ac3f376]1584
1585* aven: Clicking on a survey name in the survey tree now highlights it in
1586  the map view.  Double-clicking zooms the view to show the clicked survey
1587  highlighted.  Clicking the root clears the highlighting and double-clicking
1588  the root restores the default view.  To expand/collapse a branch, click
1589  on the "[+]" or "[-]" icon to the left of the survey name.
1590
1591* aven: The measuring line can now measure to anywhere in plan or elevation
1592  view (not just to a station!)  In plan view the horizontal distance and
1593  bearing are shown, while in elevation view the vertical distance is shown.
[90d0d71]1594
[ac3f376]1595* aven: Moving the mouse over a station in the survey view now highlights
1596  that station in the survey tree (though it may not be visible if the
1597  survey(s) it is in aren't expanded).
1598
1599* aven: Clicking on a station to centre the view now moves the mouse pointer
1600  to the new location of the station (except on Mac OS X where this isn't
1601  allowed).
1602
1603* aven: Fix which presentation toolbar buttons are shown as depressed.
1604
1605* Fix infinite loop reading 3d files with LRUD data (bug introduced in 1.1.9).
1606
1607* vim files are now installed with the correct paths (bug introduced in 1.1.9).
1608
[920b066]1609Changes in 1.1.9 (2006-07-04):
[6a2594be]1610
1611* (Unix version): Install desktop files for aven and svxedit contributed to the
1612  Ubuntu package by Phil Bull, and corresponding pixmaps.
1613
1614* Fix img to filter out cross-sections which don't match the subsurvey (if
1615  specified).  The API now returns img_XSECT_END to mark the end of a
1616  passage rather than setting a flag on the last img_XSECT of the passage.
1617
1618* Enhance integration with the vim editor - this can now colour .err files, run
1619  cavern from vim and parse error output, and run aven from vim.  Tweak the
1620  existing vim mode for .svx files to fix a few minor bugs and add support for
1621  the new "*data passage" style.
1622
1623* aven: fix drawing of the "blob" end of the measuring line on graphics cards
1624  which can't draw large enough blobs for us.
1625
1626* aven: sort out confusion about what encoding everything is in which means
1627  that the distance measured by the measuring line actually gets displayed
1628  and also fixes problems with empty menu items in non-English locales in
1629  some cases.
1630
1631* aven: redraw grey background after a menu is closed over the aven window
1632  with no survey loaded.
1633
1634* aven: fix bug which caused printing to crash (introduced in 1.1.8).
1635
1636* aven: avoid crash on some machines when opening "About" dialog before having
1637  loaded a survey.
1638
1639* aven: Translate "Plan" and "Elevation" buttons in print view dialog.
1640
1641* (Unix version): aven: Fix character set handling of cavern output.
1642
1643* cavern: Report an error if a cross-section is specified for a station which
1644  doesn't exist.
1645
1646* Updated French and Italian translations.
1647
1648* (Unix version): aven: Fix "Can't open message file `en_US' using path
[f3cfd13]1649  `${prefix}/share/survex'" error.
1650
[6a2594be]1651* Fix bug in 3d file reading on 64 bit platforms when used in STANDALONE mode
1652  (doesn't affect Survex itself, but other applications which use img.c should
1653  update their copy).
1654
1655* (Unix version): Add checks that wxWidgets is a non-unicode version (wx 2.6
1656  and later are caught by configure, whereas older wx versions are caught when
1657  trying to compile).
1658
[920b066]1659Changes in 1.1.8 (2006.06.30):
[cd39f67]1660
[c988ae4]1661* Drop support for building with wxWidgets versions prior to 2.4.0
1662  (which was released on 2003-01-07).
1663
[9577fcc]1664* aven: Printing through aven now uses settings from the "[aven]" section
1665  of print.ini, and support for hierarchical sections (using "like=")
1666  has been disabled.
1667
[ecf2d23]1668* aven: Change mouse actions to be compatible with those in Survex 1.0.
1669  The mousewheel now zooms in/out (it doesn't do anything in 1.0) and
1670  left drag is now smart about not rotating and zooming at the same
1671  time.
1672
[d1628e8e]1673* aven: Highlighting stations now happens as you type, and pressing
1674  "Enter" or clicking the "Find" button now pans and zooms to show the
1675  highlighted stations.
1676
[e67ed1b]1677* aven: Left-clicking away from a station now cancels measuring line.
1678
[3ddd351]1679* aven: Setting view to North, South, East, or West is now animated like
1680  the tilt from plan to elevation.
1681
[c988ae4]1682* aven: Fix presentation saving to also write "." for decimal points and
1683  presentation loading to accept either "." or ",".
1684
1685* (Unix version): aven: Add text for all toolbar items so that aven
1686  will work with the Gnome desktop preference for displaying toolbars as
1687  icons with text or just text (wxWidgets needs fixing first though).
1688
1689* (Unix version): aven: Remove the ability to detach the menu bar (yell
1690  if you actually used it and I'll restore it!)
1691
1692* aven: Add "all survey files" option to the "open file" dialog.
1693
[84f1ed1]1694* (MS Windows version): aven: Fix cursor keys to pan survey.
1695
[a884696]1696* (MS Windows version): Built with wxWidgets 2.6.3 instead of 2.6.2.
1697
[9fe7af4f]1698* (MS Windows version): Fix installer to work on Windows 2000 or XP if
1699  run by an unprivileged user.
1700
1701* (MS Windows version): Upgrade to the latest version of InnoSetup (the
1702  installer builder we use) and include new installer translations for
1703  UK English, Spanish, Brazilian Portuguese, Italian, Romanian, and Slovak.
1704
1705* (MS Windows version): aven: Include Catalan and Brazilian Portuguese
1706  translations of messages for wxWidgets (the GUI library we use).
1707
[cd39f67]1708* aven: Disable "Highlight exported points" if there aren't any.
1709
[afffec4]1710* Updates to French translation from Michel Bovey.  Also updates to German,
[5e74c26]1711  Italian, Catalan, Spanish, and Romanian translations.
[581624b]1712
[38a192d]1713* (Unix version): test suite: fix smoke test to pass even without X running
1714  (it was meant to but the code had a bug).
1715
[5892e08]1716* aven: Check if OpenGL is available and exit cleanly with a helpful error
1717  if it isn't.
1718
[879e9c3]1719* (Unix version): aven: Fix --help and --version to work without a working
1720  X display (provided it's built with wxWidgets 2.5.1 or newer).
1721
[c8f929b]1722* aven: Automatically select the presentation tab of the notebook when the user
1723  selects "New Presentation" or "Open Presentation".
1724
1725* aven: Fix "Delete" in the presentation list to not get passed on (and so not
1726  reset to default view as well).
1727
1728* aven: Fix Ctrl+Insert in the presentation list not to segfault if the list is
1729  empty.
1730
1731* aven: Fix Cursor Up and Down in the presentation list to move the highlight
1732  up and down instead of being passed on and moving the survey.
1733
[9ad92cc]1734* aven: Improve SVG output compatibility.  Tested with Mozilla Firefox 1.5,
[ecf2d23]1735  Adobe's SVG browser plugin, Gimp 2.2.8, Gqview 2.0.0, Opera 8.5,
1736  Safari 2.0.3, and InkScape 0.42.
[9ad92cc]1737
1738* aven: Put a 5mm border around exported SVG files to allow for station markers
1739  and non-zero width lines.
1740
1741* aven: Fix crash when exporting as SVG or Sketch if labels or surface data
1742  was turned on.
1743
1744* aven: Actually close the file we're exporting which fixes problems with it
1745  not always being fully written.
1746
[920b066]1747Changes in 1.1.7 (2005.10.18):
[6662d02]1748
1749* cavern: Add validity checking for dates in *date commands (with feature
1750  test in testsuite).  A date entered as just "year" or "year.month" now
1751  becomes a date range for the relevant period (previously it became a single
1752  date near the middle of that period).
[e0c7cd1]1753
[8add4c9]1754* extend: Fixed 2 uninitialised flags (should fix erratic behaviour on
1755  with MS Windows).
1756
[9f524ee]1757* extend: Default output name for a file called input.3d is now input_extend.3d
1758  rather than just extend.3d (which was annoying if you wanted to extend
1759  several surveys in the same directory).
1760
[185d793]1761* aven: OpenGL 2.0 always includes support for point sprites so rework
[3efd6b6]1762  our check for them to include that knowledge.
[185d793]1763
[3515947]1764* aven: Regenerate depth bar if user switches to/from metric units.
1765
[1235f9b]1766* aven: Don't clear the "there" mark just because the mouse pointer has
1767  moved off a station.
1768
[4299674]1769* aven: When processing a .svx file, put the resultant .3d file in the
[d74279d]1770  same directory (since that's where we then try to load it from).
[4299674]1771
[60dbe70]1772* aven: Fix labelling of date colouring on 32 bit platforms.
1773
[125c9ea]1774* aven: If "colour by date" is on and we load a survey with no date info
1775  (or all surveyed on the same date) then set "colour by none".
1776
[ec58e3d3]1777* aven: Make the error dialog modal and remove a signal handler once it
1778  has fired to prevent endless (or seemingly endless) cascades of error
1779  dialogs.
1780
[8add4c9]1781* aven: Enforce a minimum object volume diameter of 1m to avoid problems
1782  if a survey file with only one station in is loaded.
1783
[6662d02]1784* aven: Fix problems with indicators disappearing when we're drawing
1785  blobs and/or crosses the slow (but always supported) way.  (Problem
[d74279d]1786  introduced in 1.1.6).
[6662d02]1787
[b65c13f]1788* (Unix version): aven: Really stop setting extra toolbar margin when using
1789  GTK2.0.  The attempt to fix this in 1.1.3 failed because __WXGTK12__ is
1790  set for GTK+ 1.2 or *any later release* so is true for GTK+ 2.0 too!
1791
[17cce5f]1792* (Unix version): aven: Add details of which of wxGTK, wxMotif, and wxX11
1793  we've been compiled with, and which GTK+/Motif version where appropriate.
1794
[affaeee]1795* (Unix version): Fixed build on Fedora Core 3.
1796
[618b01f]1797* documentation: Updates to 3d file format specification from Mike McCombe.
1798
[920b066]1799Changes in 1.1.6 (2005.10.10):
[7e01c87]1800
1801* (MS Windows version): Distribution is about a third smaller than 1.1.5
1802  (mostly because mingwm10.dll is no longer required).
1803
[b88b171]1804* aven: If aven is asked to load a .svx, .dat, or .mak file, run cavern on
1805  it, showing cavern's output in a window (with errors and warnings clickable
1806  to load the offending file into an editor), and then loading the resulting
1807  3d file.
1808
[7e01c87]1809* aven: Added "Colour by Date" option.
1810
1811* aven: Disable "Colour by Depth" option if there's no elevation variation.
1812
1813* aven: Don't crash if trying to load a survey with no elevation variation.
1814  Instead turn off depth colouring.
1815
[8ea82aa]1816* aven: Export as HPGL added.
1817
[887c26e]1818* aven: Improved update of mouse coordinates and measuring line (thanks to
1819  Martin Green).
1820
[7c29c976]1821* aven: Show the coordinates of either the mouse pointer or the nearest
1822  survey station to it (if there is one near enough).  Showing both was
1823  confusing and meant the status bar overflowed on smaller displays.
1824
[7e01c87]1825* aven: When printing an extended elevation, don't show bearing and elevation.
[bd21214]1826
[7e01c87]1827* aven: Don't lock "flat" surveys which aren't extended elevations - a
1828  flat survey with LRUD data isn't flat any more!
1829
1830* aven: When we have to draw blobs and crosses the slow way (because the
1831  graphics hardware doesn't support the fast way), draw them so that they
1832  should appear at the correct depth into the 3D scene instead of on top
1833  of everything else.
1834
1835* aven: Make "play presentation backwards" icon green to match the other
1836  presentation icons.
1837
1838* (MS Windows version): aven: Mouse clicks on the survey view now set the
1839  keyboard focus there.
[bd21214]1840
[b46bf92]1841* (MS Windows version): aven: Fix first redraw of a newly loaded survey.
1842
[796d7bf]1843* (MS Windows version): aven: Fix redrawing of measuring line.
1844
[7e01c87]1845* cavern: Store dates for img_XSECT.
1846
1847* cavern: Fixed small one-off memory leak if you specify -o more than once.
1848
[b88b171]1849* (Unix version): Check environmental variable LC_MESSAGES when deciding what
1850  language to use for messages.
1851
[7c29c976]1852* (MS Windows version): "Print" on a 3d file now prints through aven rather
1853  than the separate printer driver (Unix has done this for some time).
1854
[8ea82aa]1855* Removed old printer drivers.
1856
[7e01c87]1857* img library: When creating a 3d file, ignore img_XSECT if we've been asked
1858  to write a file format version which doesn't support it.
[8ea82aa]1859
[920b066]1860Changes in 1.1.5 (2005.09.20):
[106cfdf]1861
1862* (MS Windows version): aven: Fixed crash on start-up (introduced in 1.1.4).
1863
[4ba80e0]1864* aven: Make blobs round like they are in Survex 1.0.
1865
1866* aven: If the graphics drivers don't support drawing blobs using OpenGL
1867  point markers, fall back to drawing filled circles.
1868
[95ce35f]1869* aven: If the graphics drivers support it, draw crosses as texture mapped
1870  OpenGL point markers which is much faster.
[90d0d71]1871
[95ce35f]1872* aven: Cross size increased to match Survex 1.0.
1873
[cd78148]1874* aven: We must update which blobs are displayed if display of surface or
1875  underground legs is toggled.
1876
[f5627353]1877* cavern: Fix handling of a *solve followed by survey data, none of which is
1878  attached to the previous data.
1879
[dfe4a520]1880* cavern: Fixed "No survey data" error when a *solve is followed by another
1881  *solve (or the implicit solve at the end of processing) with no data between
1882  them.
1883
[920b066]1884Changes in 1.1.4 (2005.09.19):
[4855072]1885
1886* aven: Added Aven's icon to the "About" dialog.
1887
1888* aven: Use localised character for the decimal point (e.g. "," in most
1889  continental European countries).
1890
1891* aven: Previously the survey tree would get focus and then take keypresses
1892  (e.g. "P", "L", "Delete").  Now we pass most keypresses across so they
1893  operate on the cave, and transfer the input focus across when we do.
1894
1895* aven: Make pressing "Return" in the tree control expand/collapse a subtree.
1896
1897* aven: Speed up intialisation by delaying creation of OpenGL lists until
1898  they're needed.
1899
1900* aven: Added Mark Shinwell's bounding box with shadow of the survey.
1901
1902* aven: Disable the "Tubes" button/menu item when there's no LRUD data.
1903
1904* aven: Reworded "Restore Default Settings" as "Restore Default View".
1905
1906* (Unix version): aven: Set sensible default margins for printing and preserve
1907  any margin values the user specifies between runs (previously margins
1908  defaulted to 0 each time aven was run).
1909
1910* Documentation: Document *DATA PASSAGE in the manual.
1911
[920b066]1912Changes in 1.1.3 (2005.09.07):
[0e558e5]1913
1914* (Microsoft Windows version): Fixed build problems.
1915
1916* cavern: Allow OMIT character (-) for left/right/up/down.
1917
1918* aven: Remove an unnecessary menu separator.
1919
1920* aven: Fix "Find" and "Hide" toolbar buttons to work with GTK2.0.
1921
1922* aven: Make the tooltip for "Hide" show the number of found stations.
1923
1924* aven: If * or ? is used in a glob-style pattern, force a non-substring match.
1925
1926* aven: Enable "New Presentation" when there's a 3d file loaded, rather than
1927  when there's a presentation loaded.
1928
1929* aven: Make entrances green in side panel tree list to match green blobs used
1930  in cave view.
1931
1932* aven: Don't show surface labels if we're not showing surface data, etc.
1933
1934* aven: Merge "Start Rotation" and "Stop Rotation" into "Toggle Rotation" and
1935  make "Space" the key for this.  Keep Return working "Stop Rotation" so
1936  existing users are happy, but don't advertise it.
1937
1938* aven: Normalise filename by adding any extension used, and use the normalised
1939  filename for file history and window title.
1940
1941* (Unix version): aven: Stop setting extra toolbar margin when using GTK2.0
1942  as the toolbar buttons already have a sensible margin - the extra margin is
1943  only needed with GTK1.2.
1944
1945* aven: Fix handling of plumb legs in tube model.
1946
1947* aven: Fixed swapped L and R in tube model.
1948
1949* extend: Preserve UD cross-section information in extended elevation.
1950
1951* extend: Add new messages for John Pybus' enhancements.
1952
1953Changes in 1.1.2 (never formally released):
[8faa5d8]1954
1955* Added support for LRUD data in .svx files, in .3d files, and aven can
1956  now load and display it on screen and on printouts.  The ability to "fake"
1957  LRUD data in aven is gone for now but will reappear in some form later.
1958
1959* cavern: Removed support for writing Chasm's 3dx format.  We're going to
1960  fold any desirable missing chasm functionality into aven.
1961
1962* aven: Rearranged mouse actions as discussed on the mailing list.  Added
1963  cursors for each different mouse action to help the user learn what each
1964  does.  Also added cursors for the "compass" and "clino" as well as the
1965  scalebar to suggest to the user that they can be dragged to change the view.
[1a09e2c]1966
[0e558e5]1967* (Unix version): aven: Don't segfault if LANG isn't a known language.
[8faa5d8]1968
1969* tests/smoketest.tst: If X windows is running, check that we can run aven
1970  with --help and --version.
1971
1972* tests/cavern.tst: Fixed cavern.tst to warn if it is skipping a test because
1973  no results are listed for it.  This revealed that there was a "newline" test
[6225339]1974  which should have been called "badnewline", and was a broken testcase too!
[8faa5d8]1975  Fixed all these problems.
1976
1977* cavern: Applied Simeon Warner's patch for handling backcompass, backclino,
1978  and omitted forward compass/clino readings in Compass DAT files.  Added
1979  a feature test for this to the testsuite.
1980
1981* It no longer makes sense to have an option not to build aven or to build aven
[0e558e5]1982  without OpenGL so remove old machinery for this from configure and the
1983  sources.
[8faa5d8]1984
[0e558e5]1985* (Unix version): configure: Check if "-lXxf86vm" is needed.
[8faa5d8]1986
1987* configure: Better output for strcasecmp test.
1988
1989* aven: Fix crosses to work much better.  Not a total fix - their position
1990  in the Z buffer isn't correct and they're rather slow to plot.
1991
1992* aven: Don't regenerate the hittest grid every time the mouse moves while
1993  animating, which solves the mysterious pausing effect (thanks go to Martin
1994  Green for spotting this!)  Also clear all the status bar coordinates when
1995  animating.
1996
1997* aven: Sort out clashing menu shortcuts in some languages.
1998
1999* aven: Fixed compilation problem on x86_64
2000
2001* SPUD: Pruned out stuff which has been done or which is not actually relevant
2002  to this branch.
2003
2004* Merge various changes from 1.0 branch:
2005
2006  + aven: Port over "printing from aven" functionality.
2007
2008  + aven: Port over "export as" functionality,
2009
2010  + Add David Loeffler's vim mode for .svx files.
2011
2012* aven: Fix check for whether a label is behind us in perspective view.
[1a09e2c]2013
[8faa5d8]2014* aven: Don't use an opengl list for drawing the indicators - we typically make
2015  a new list each time we plot them anyway.
2016
2017* Remove lingering traces of support for RISC OS and pre-386 MSDOS
2018
2019* aven: Set icon on non-Windows platforms too.  This means that with
[0e558e5]2020  WindowMaker on Unix you get an icon on the AppIcon by default.
[8faa5d8]2021
2022* configure: Update wxWindows checks to handle newer wx versions.
2023
2024* Make all maintainer perl scripts "use bytes;" to avoid utf-8 double encoding
2025  problems.  They also all require Perl 5.8 now (hopefully this isn't an issue
2026  for anyone building from CVS).
2027
2028* acinclude.m4: Quote macro name for fix autotools warning.
2029
[4855072]2030* Documentation: "tilt up" is "'" not ",".
[8faa5d8]2031
2032* aven: Add support for mousewheels (to tilt the cave).
2033
2034* aven: Fixed twisted transitions to and from pitches in certain cases.
2035
[0e558e5]2036* aven: Pick a sensible initial window size when the user's desktop is spread
2037  over more than one monitor (works best with wx2.5 or newer, but try to do
[8faa5d8]2038  better with wx2.4 or earlier as well).
2039
2040* aven: Initialise GfxCore slightly later to avoid visual glitch from notebook
2041  contents being visible before any survey is loaded.
2042
2043* aven: Allow a coloured texture to be used
2044
2045* aven: Don't initialise until we have data (to the user, this means the window
[0130bc4]2046  is default colour (grey for most systems) not black until a survey is
2047  loaded).
[8faa5d8]2048
2049* aven: Fixed weird "shadowed" icons.
2050
[920b066]2051Changes in 1.1.1 (2004-10-06):
[a7aa27d9]2052
2053* (Microsoft Windows version): aven: Hopefully fix loading a survey file at
[1a09e2c]2054  startup.
[a7aa27d9]2055
2056* aven: Delay loading the bitmap for the "About" dialog until it is first
2057  needed.  We want start up to be as quick as possible.
2058
[920b066]2059Changes between 1.0.32 and 1.1.0 (never formally released):
[edb6576]2060
[91e416e]2061* NOTE: Survex 1.1.X releases are development snapshots made available for
2062  the purposes of allowing wider testing and getting more user feedback.  Once
2063  the code has stabilised the version number will be raised to 1.2.0.
[edb6576]2064
[91e416e]2065* aven: Now uses OpenGL for 3d rendering - you may need to install drivers if
2066  you're using Windows 95 - these can be obtained from:
2067  http://download.microsoft.com/download/win95upg/info/1/W95/EN-US/Opengl95.exe
[edb6576]2068
[91e416e]2069* aven: Solid passages - passage dimensions are currently inferred from
2070  the leg length (pretty effective as you can measure longer legs in
2071  larger passages).  Use of real LRUD data coming soon...
[edb6576]2072
[91e416e]2073* aven: Depth colouring is now continuously varying.
[edb6576]2074
[0580c6a]2075* aven: Colour by depth can now be turned off (and there's the start of a
2076  framework for properly implementing colour by date, error, etc).
2077
[4261983]2078* aven: Find stations moved onto the toolbar and now uses a simple wildcarded
2079  match (? matches any character, * matches any number of characters).
2080
2081* aven: We now use the status bar for coordinates, distances, etc to make
2082  better use of screen space.
[edb6576]2083
[f80077a]2084* aven: Full screen mode (F11).
[edb6576]2085
[6abab84]2086* aven: Perspective view.
2087
[91e416e]2088* aven: Context sensitive cursor shape - needs more work.
[edb6576]2089
[91e416e]2090* aven: Mouse actions changed (hopefully they're now more natural, but
2091  you may find the change disorientating - feedback wanted on this).
[edb6576]2092
[1690fa9]2093* aven: Added "presentations" which allow you to set up fly-through paths
2094  and load/save/run them.
2095
[0580c6a]2096* aven: A presentation can be exported as a movie file.
2097
[045e2af]2098* aven: Added Save screenshot facility.
2099
[c60062d]2100* aven: Depth fogging option.
2101
[0580c6a]2102* aven: Added Smooth Lines option.
2103
2104* aven: Added Textured Walls option.
2105
[f433fda]2106* aven: If a survey has surface legs but no underground legs, default to
2107  showing the surface legs.
2108
[0580c6a]2109* cavern: Dates given to *date are now stored in the 3d file.
