RevLine 
[820eb08]1Changes in 1.2.21 (2015-07-15):
[31e9b72]2
[03c259e]3* aven:
4
[22f17f1]5  + Implement exporting of survey legs in KML format.
6
[03c259e]7  + Put "paddle" placemarker icons on stations in exported KML files, using the
8    same colour coding for entrances, fixed points and exported points as aven
9    does.
10
11  + Use wxGetenv() to read the SURVEXEDITOR variable, so we can accept Unicode
12    values on Windows.
13
14* cavern:
15
[22f17f1]16  + Fix coordinate systems using latitude and longitude - PROJ.4 wants these in
17    radians, but we were passing degrees, which would generally cause the
18    conversion to the output coordinate system to fail.  Reported by Wookey.
19
20  + Fix *fix with standard deviations when *cs is in use.
21
[03c259e]22  + Fix use after free after *solve.  This only occurs if a leg between the two
23    exact same stations appears right before and right after the *solve, which
24    is unlikely in real data, but the testsuite has an instance of this.  This
25    was introduced by the repeat leg averaging added in 1.2.17.
26
27  + Fix small memory leak when solving network.  This doesn't really matter
28    when solving at the end of processing as cavern will exit after that, but
29    if *solve is used we continue processing after solving.
30
31* Remove compatibility handling for specifying a country variant of a language
32  in SURVEXLANG using "-" with a lower case country code (e.g. "en-us") - we
33  changed to the standard "en_US" way back in 2001.  This code was mangling
34  character sets with a "-" in, and is no longer useful.
35
36* Ignore any "@<something>" modifier in the language code.
37
[22f17f1]38* Remove references to SpeleoGen from the documentation - it hasn't been
39  updated for many years, and can't read recent versions of the .3d format.
40
41* Strip documentation references to obsolete versions of MS Windows.
42
[7027ea1]43Changes in 1.2.20 (2015-06-26):
[0eaf4b1]44
45* aven:
46
[6de8e942]47  + When printing, use the top margin rather than the right margin to calculate
[31e9b72]48    the height of the printable area.  In practice, the two values seem to be
49    the same or very similar by default.
[0eaf4b1]50
51  + Avoid assertion if the about dialog image fails to load.  Reported by Phil
52    Maynard.
53
54  + Optimise the size of the about dialog images.
55
[7027ea1]56  + Add support for reading terrain data which isn't in a .zip file.
57
58  + Force a refresh after loading terrain data so that it gets displayed right
59    away.
60
61  + Make checks for terrain data extensions in zip files case insensitive.
[6de8e942]62
63  + If reading terrain data fails, always report an error and never try to
64    display it.
65
66* cavern: Allow clino readings in diving style data, suggested by Andrew
67  Atkinson.  Currently these readings are ignored, but a future version will
68  check that they're consistent with the angle given by the depth gauge and
69  tape, and perform suitable averaging.
70
[0eaf4b1]71* Remove lingering traces of svxedit.
72
73* configure: Fix to allow compiling without libav/ffmpeg, as was possible
74  before 1.2.19.
75
76* (Unix version): Install the filetype and aven application icons under
77  /usr/share/icons/hicolor, which is where they're expected to be these days.
78
79* (Unix version): Add %f to Exec in survex-aven.desktop.
80
81* (Mac OS X version): Remove useless extra copy of about box images from OS X
82  disk image.
83
[6de8e942]84* (Mac OS X version): Only ship one copy of each of the translations.
85
[0eaf4b1]86* (Mac OS X version): Reduce the size of the aven binary by disabling a load of
87  libav features we don't use.
88
89* (Microsoft Windows version): Reduce the size of the aven binary by disabling
90  a load of libav features we don't use.
91
92* (Microsoft Windows version): Update message files to fix a missing Chinese
93  message in the installer.
94
[1dc99d1]95Changes in 1.2.19 (2015-06-18):
[f96ac93]96
97* aven:
98
99  + Fix exporting to GPX, KML and HPGL, which all failed to write the header to
100    the exported file in 1.2.18.
101
[2dac61e1]102  + Add exporting to Survex .pos format.
103
[4b67f71]104  + If the measuring line isn't currently active, pressing "Escape" will now
105    exit full screen mode.
106
107  + (Mac OS X version): Change the shortcut for full screen mode to be the
108    standard Ctrl+Command+F (rather than Shift+Command+F which we have been
109    using since 1.2.7).
[2dac61e1]110
[f96ac93]111  + (Mac OS X version): When we centre the view on the station this can
112    generate a mouse move event, so clear the variable which says we are
113    dragging before we process a left click on a station.  This avoids random
114    rotations of the survey when clicking on a station, reported in #47 by Hugh
[2dac61e1]115    St. Lawrence.
[f96ac93]116
117  + (Mac OS X version): Force use of a non-native toolbar to stop the toolbar
118    icons from being rescaled and looking fuzzy.
119
120  + (Mac OS X version): Remove code added in 1.2.18 which tries to set stop the
121    toolbar icons from being rescaled, but which requires an unreleased version
122    of wxWidgets, had a typo in, and doesn't actually seem to work anyway.
123
124  + (Mac OS X version): Drop out of full screen mode if the mouse is mode to
125    the top of the screen, since we can't seem to display the menu bar in this
126    case like we do on other platforms.
127
[739440f]128  + (Mac OS X version): Enable aven's movie export feature.
129
[2dac61e1]130  + (Mac OS X version): Enable wxDisplay when building wxWidgets to better
131    support multi-monitor setups.
132
[f96ac93]133  + (Mac OS X version): Silence warning visible when aven is run from a
134    terminal about a missing CFBundleTypeRole.
135
[4b67f71]136  + When reading terrain data from a .zip file, report an error if the .zip
137    file is bad, or if it doesn't contain any terrain data we recognise.
138
[f96ac93]139  + Tweak error message in terrain reading code to distinguish two failure
140    cases.
141
[2dac61e1]142  + Add viewing angles and scale to footer, and shorten some of the other items
143    to make room for this extra information.  (Fixes ticket #52, reported by
144    Erin Lynch)
145
146  + If the footer is wider than the printout width, scale down the font used
147    so that it exactly fits; if the footer is narrower, than space out the
148    items in in so it uses the full width.
[f96ac93]149
150  + If the saved size for aven's window exceeds the current display size
151    (mostly likely because we're now plugged into a smaller monitor), then
152    reduce the size of the window to fit the display.  If the saved size is <
153    (480x320), increase it to at least that, as aven isn't usable in a smaller
154    window.
155
[2dac61e1]156  + Remove crude bodge which tries to pick a nicer initial window size when
157    using wxWidgets without wxDisplay on a multi-monitor setup - aven now opens
158    with the same size window it had when it was closed, so the initial size is
159    only relevant on the first ever run.
[f96ac93]160
161* Assorted translation updates.  Notably Indonesian is at 100% again.
162
163* Stop trying to catch and report signals.  The only real reason to do it is so
164  we can say "Bug in program detected! Please report this to the authors"
165  before we exit, but when the program crashes that's pretty obvious.  In aven
166  we try to pop up a message box for this message, which may fail due to
167  whatever caused the signal, while with the command line tools there's no
168  great benefit over just letting the shell report the signal.
169
[4b67f71]170* Use pkg-config to probe for libav and proj, which sorts out the correct flags
171  for building on OS X against a static install of libav.
172
[3f02aa4]173Changes in 1.2.18 (2015-06-03):
[2595419]174
[4a8031f]175* aven:
[a5670c7]176
[4a8031f]177  + Add support for reading terrain data (from a zip file containing either an
178    SRTM .hgt file, or an ESRI .bil file and associated metadata files), and
179    rendering it as a transparent surface.
[a5670c7]180
[4a8031f]181  + Remove actions from 'Orientation' and 'Rotation' menus which you wouldn't
182    sanely want to perform from the menu.
[a5670c7]183
[4a8031f]184  + Create a "Colour by" submenu of the "View" menu to house the various
185    colouring options.
[a5670c7]186
[4a8031f]187  + Add "Colour by Gradient" and "Colour by Length".
[a5670c7]188
[4a8031f]189  + Make the button to dismiss the "About" dialog "OK" rather than "Close",
190    which seems more logical, and also allows the dialog to be closed by
191    pressing "Escape".
[a5670c7]192
[38e5701]193  + Destroy any existing clipping region before we write the page footer.
194    Hopefully solves ticket #52, reported by Erin Lynch.
195
[4a8031f]196  + Don't round bearing and tilt angles to integers when printing and
197    exporting.
[a5670c7]198
[38e5701]199  + Add passage export for EPS format.  (Partly addresses ticket #4)
200
201  + Add JSON export.  This should be regarded as experimental, and the format
202    is quite likely to change.
203
[4a8031f]204  + Pressing F6 now toggles the display of rendering stats, currently FPS
205    (Frames Per Second) and the number of triangles in the terrain mesh.
[a5670c7]206
[4a8031f]207  + Add a menu item and toolbar button to show the cavern log window if the
208    currently shown survey data was processed by aven.  Reported by Hugh St
209    Lawrence in #47, and by Dave Clucas and others previously on the list.
210
211  + Add "Save Log" button to Aven's cavern log window.
212
213  + In cavern log window, highlight "error" markers in red and "warning"
214    markers in orange.
215
216  + Rework code to read cavern's output.  In particular, we no longer mix
217    buffered and non-buffered system calls.
218
219  + Aven's support for reading colours and font sizes for printouts from
220    print.ini has never worked - the contents of the ini files are ignored due
221    to a bug which has been there since the code was added in 2005 - but nobody
222    has ever complained.  So just strip out that code entirely - we should
223    support setting the colours and font sizes, but a GUI interface for setting
224    them would be better.
225
226  + Fix to compile with a Unicode build of wxWidgets 2.8.  Reported by Bill
227    Gee.
228
229  + Take the width of the messages used above the compass and clino into
230    account when calculating how much space to allow for them - now the labels
231    won't overlap or be cut off in translations where they are long.
232
233  + (Mac OS X version): Attempt to address the size of the toolbar icons.
234
235* cavern:
[0476b10]236
[38e5701]237  + Reject *fix with SDs which aren't all positive.  (fixes#2, reported by
238    susscorfa).
239
[4a8031f]240  + Use the currently set units when outputting measurements in warnings,
[38e5701]241    errors, and the stats at the end of the run.  Requested by Bill Gee.
[4a8031f]242
243  + Include column number when a *include file isn't found.
244
245  + Show 'error' in front of error messages, like we show 'warning' in front of
246    warnings.  Fixes #48, reported by Wookey.
247
248  + Increase the threshold for warning that fore and back measurements differ
249    from 2 SDs to 3 SDs.
250
251* findentrances: If the 3d file specifies the coordinate system, use it.
252
253* svxedit: Remove svxedit - while an editor with built-in knowledge of survex
254  would be nice to have, svxedit doesn't really offer that, and it looks ugly
255  in a modern desktop.
[a5670c7]256
[dd65182]257* If we run out of memory while reading a processed survey data file, include
258  the filename in the error message.
259
[4a8031f]260* Many translation updates - notably Indonesian and Russian are now the two
261  most complete translations.
[dd65182]262
[4a8031f]263* (Microsoft Windows version): Add code page 1252 mappings for fancy quotes.
[dd65182]264
[4a8031f]265* Transliterate gradient and infinity symbols if the current character set
266  lacks them.
[dd65182]267
[4a8031f]268* Add SVG version of .plt icon.
269
270* Manual:
271
272  + Add complete list of quantities you can set SDs for.  Thanks for Wookey for
273    highlighting that the previous list was incomplete.
274
275  + Document averaging of a group of repeated readings.
[dd65182]276
[4a8031f]277  + Add a link to the sample data from the manual.
[dd65182]278
[4a8031f]279  + Remove references to contact addresses which are no longer there.  Remove
280    offer to post people floppies, and references to a CD image which isn't
281    available for download.
282
283* Remove non-breaking spaces from the diffpos and extend manual pages, as they
284  actually make the output formatting worse (presumably these used to work
285  around a since-fixed bug in one of the docbook processing tools).
[2595419]286
[4a8031f]287* doc/TODO.htm: Update.
[dd65182]288
[3f02aa4]289* Fix to compile without warnings with 'g++ --std=gnu++11'.
290
[1646310]291Changes in 1.2.17 (2015-02-24):
[a6064e2]292
293* MacOS X version:
294
295  + Update INSTALL file with current status.
296
[e067870]297  + Aven.app now has a custom icon.
[9e053fc]298
[e067870]299  + Add icons for all the filetypes supported.
300
301  + Add Finder actions for .svx, .3d, .plt and .pos files.
[9e053fc]302
303  + aven: Hide the status bar and tool bar in Full Screen mode, as wx doesn't
304    currently do this for us.
305
[a6064e2]306  + aven: Fix short-cut for toggling Full Screen mode.
307
308  + aven: Make "About" menu item appear.
309
[9e053fc]310  + aven: Fix "Close" button in about dialog.
311
312  + aven: Make custom cursors black with a white outline to match the standard
313    OS X cursor.
314
[e067870]315  + svxedit: Now wrapped up in an application bundle as svxedit.app.  It
316    still doesn't really work like a standard app though - e.g. you can't load
317    files from Finder (instead run svxedit.app and use File->Open), the font
318    size of most menu items is wrong, the icon for the app is the wish icon
319    rather than the svxedit icon, shortcuts use Ctrl not the Cmd key, and
320    probably more.  I'd probably recommend using another editor (OS X comes
321    with TextEdit.app for example).
322
323  + The documentation is now in a "Docs" directory alongside the apps, rather
324    than in the rather less obvious "share/doc/survex" directory.
325
[a6064e2]326  + Default to building for x86_64, since all modern Macs are 64 bit.
327
[9e053fc]328  + Disable use of liblzma when building wxWidgets for OS X, which was
329    preventing the build from working on OS X 10.6.8.
330
331  + Download wx sources from SF via redirecting link.  Thanks to David A.
332    Riggs.
333
334  + buildmacosx.sh: Handle the mount point for the disk image containing a
335    space.
336
[4baea3a]337  + Link with a static build of PROJ for doing coordinate system conversions.
[9e053fc]338
339  + Build wx with --disable-webview to avoid a compilation failure on OS X
340    10.10.1.
341
342  + Use wx-config --cc and --cxx to get the compilers to use for building
343    everything else, as wx adds options to them which otherwise cause linking
344    errors.
345
[4baea3a]346  + The diskimage (.dmg) file is now compressed with bzip2, which gives a
347    smaller download.  This means OS X 10.4 is required, but we probably
348    already need at least 10.5 because that's the minimum version which the
349    wxWidgets build supports by default.
350
[e067870]351  + Remove unused files and copies of files from the diskimage.
352
[a6064e2]353* cavern: If the same leg is repeated consecutively, average the readings and
354  treat as a single leg.
355
[9e053fc]356* dump3d: Report SEPARATOR used by the file being read.
357
358* aven.svg: Fix visual glitch in SVG icon for aven.  Noted by David A. Riggs.
359
360* aven:
361
362  + Greatly reduce flicker when mouse is moved to the top of the screen in full
363    screen mode and the menu bar reappears.
364
365  + For export formats where scaling is supporting, aven now actually uses the
366    scale specified in the export dialog (previously it ignored this and used
367    1:500).
368
369  + Reimplement animation so that it's based on angular change per unit of
370    elapsed time, rather than averaging the time take for the last two scene
371    redraws.  This gives smoother animation in the face of variable load and
372    scene redraw time, and should be more consistent between platforms.
373
374  + Switching to a point of the compass during auto-rotation now jumps straight
375    there rather than the two animations fighting.
376
377  + Reduce the maximum auto-rotation speed, as the previous limit was uselessly
378    fast.
379
380  + Disable stepping the rotation angle when animating (previously we only did
381    when rotating).
382
[1646310]383  + Speed up start-up a bit - rather than loading icons from individual PNG
384    files on disk, compile them into the aven binary.
385
386* (Unix version): Add "MimeType" field to desktop files so that file
387  associations work out of the box with modern desktop environments.
388
389* Add start of Hungarian translation from Imre Balogh.
390
391* Merge in many updates to the Russian translation from "vsuhachev".
392
393* Assorted minor updates to other translations.
394
395* Create scalable (SVG) versions of file type icons.
[e067870]396
[a6064e2]397* doc/manual.sgml: Remove $Id and $Date markers, as they don't get expanded now
398  we're using git.
399
[1646310]400* tests/: Improve test coverage in a few places:
401
402  + Extend tests of fore and back sights to test calibration of the back
403    compass.
404
405  + Test "Can't calibrate angular and length quantities together" error.
406
407  + Check that "*set names ." works when "." is also the decimal point.
[a6064e2]408
[03d0e8b]409Changes in 1.2.16 (2014-10-17):
[9aa10ad]410
411* aven: Add KML export (stations only currently).
412
[f480117d]413* aven: Allow measuring line to measure from anonymous stations.  (Fixes #44)
414
[9aa10ad]415* aven: Fix corrupted names in exported files.
416
417* aven: Fix error log window under wxWidgets >= 2.9 to include the system
418  information before the first log message like it does under wxWidgets 2.8.
419
420* cavern: Add support for "*cs JTSK" and "*cs JTSK03".
421
422* tests/: Improve test coverage.
423
[7bd113b]424* Translation updates for many languages, plus the start of translations to
425  Greek and Polish.
[9aa10ad]426
427* Fix to build against wxWidgets 3.0 built with assertions disabled.  Reported
428  by Martin Sluka.
429
430* Fix warnings when compiling with clang (which is the default compiler on
431  Mac OS X).  Reported by Martin Sluka.
432
[44f51ca]433Changes in 1.2.15 (2014-08-14):
434
435* cavern: The *cs command now also supports "long-lat", "s-merc" (for "Web
436  Mercator"), EPSG and ESRI codes, "eur79z30", "ijtsk" and "ijtsk03".  This
437  means that we now support all the coordinates systems which Therion does,
438  except for a few which don't have X=East and Y=North.  The documentation
439  for *cs has also been improved.
440
441* aven: We no longer persist full screen mode between runs - it's not a
442  standard behaviour of desktop programs, and it's too easy to go into full
443  screen mode from the menu and then not be able to get out again because you
444  don't know the required key shortcut. (ticket#39)
445
446* aven: When in full screen mode, moving the mouse to the top of the screen now
447  makes the menu bar appear.  This provides a non-shortcut way out of full
448  screen mode, as well as making it easier to perform other operations while in
449  full screen mode.  The current implementation gives an annoyingly flickery
450  transition, but hopefully we can improve this in future. (ticket#39)
451
452* (MacOS X version): If built with wxWidgets >= 3.1.0 (which is still in
453  development), we now call EnableFullScreenView() which improves the full
454  screen mode experience on OS X 10.7 and later.
455
456* img library: Improve documentation for img_ERROR_INFO.
457
458* tests/: Ship some missing .out files and compare.tst.
459
460* tests/: cavern.tst testcase back2 is now actually used.  Fix a bug in this
461  testcase, and extend it to cover a variant of the situation reported as a bug
462  in therion by Bill Gee to the therion list.
463
464* (Linux version) survex.spec: Add run-time requirement on proj and proj-epsg
465  for the survex package and on tk for the svxedit package.
466
[6a87cce]467Changes in 1.2.14 (2014-07-05):
[5c676e2]468
[1efeb6d]469* img library: Add ability to store a PROJ4 string describing the coordinate
470  system in use in 3d v8 files.
471
472* aven: If the 3d file specifies a coordinate system, then use it for exporting
473  to formats which need to know (currently GPX).  If the input file doesn't
[6a87cce]474  specify the coordinate system, allow the user to enter a PROJ4 string in the
475  export dialog.
[1efeb6d]476
[ea59b58]477* aven: You can now quickly zoom to a particular area by holding down the
478  "Shift" key and dragging with the left mouse button to create a rectangular
479  "rubber band box" around the area you wish to zoom to.  If you release the
480  "Shift" key while still dragging, the box is centred on the start point
481  rather than having one corner there.
482
[26e7fa4]483* aven: Fix exporting of passage tubes in elevations and extended elevations
484  - previously up and down were getting drawn across the page!
485
[5c676e2]486* aven: Fix "Cancel" to work on the print/export dialog, broken by changes in
487  1.2.13.  (Reported by Brian Clipstone)
488
[515b83e]489* aven: Fix the conditions on which the menu item "Cancel measuring line" is
490  enabled - previously it was hard to actually cancel it via the menu.
491  Reported by Hugh St Lawrence.
492
[5c676e2]493* aven: Fix wx assertion failures when showing hit test debug view on platforms
494  such as 64-bit Linux.
495
[2c5ec88]496* aven: When viewing from above, show "Plan" above the "clino" which indicates
497  the tilt angle (instead of "Elevation -90°").
498
[5c676e2]499* aven: The extended font data now loads faster, and also uses less memory on
500  64-bit platforms.
501
[ea59b58]502* aven: Dragging the vertical divider between the side panel and the 3D view
503  now only updates when you finish the drag, as redrawing continuously just
504  looks clunky except on an ultra-fast machine.
505
[2c5ec88]506* aven: (German translation) Abbreviate "Blickrichtung" so it doesn't overfill
507  the space available in the aven UI.
508
[1efeb6d]509* cavern: Add a *cs command to allow setting the coordinate system for *fix
510  commands, and the coordinate system used for processed survey data.  The
511  latter is now stored in 3d v8 format files.
[ea59b58]512
[515b83e]513* cavern: Add support for 'L' flag (exclude from length) in Compass .dat files
514  and handle it in the same way as the "DUPLICATE" flag in .svx files.
515
[6a87cce]516* cavern: If there's more than one *fix command with coordinates, still
517  actually fix the second and subsequent ones, to avoid triggering bogus errors
518  about unconnected surveys.
519
520* cavern: If there's more than one *fix command with coordinates, report the
521  station name of the previous one, plus the file and line number where it was.
522
[67a0fc6]523* cavern: Fix handling of the rather contrived case of *fix with no coordinates
524  followed by *solve and then another *fix with no coordinates not to access
525  freed memory.
526
[1efeb6d]527* dump3d: Report any specified coordinate system.
528
529* doc/3dformat.htm: Update to document how the coordinate system is stored.
530
[2c5ec88]531* (Microsoft Windows version): Include dump3d in the installer.
532
[5c676e2]533* Fix a compiler warning.
534
535* Improve test coverage.
536
[0d365be]537Changes in 1.2.13 (2014-05-15):
[acbb5b1]538
[8ccd1d8]539* aven: Fix --print option to wait for printing to happen before exiting
540  (previously it would exit right after opening the print dialog, so you
541  couldn't actually print anything out using it).
542
[acbb5b1]543* aven: Increase the threshold for how close the pointer needs to be to a
544  station from 5 pixels to 7 to try to help touchscreen users.  Reported by
545  Hugh St Lawrence.
546
[0d365be]547* aven: Add "fat finger" mode, toggled by pressing F2, to allow investigating
[8ccd1d8]548  if increasing the minimum pointer to station threshold helps Hugh's problems
549  with using aven on a touch screen device.
550
[acbb5b1]551* aven: The measuring line was unable to see stations which had just been
552  revealed by toggling surface or underground legs on - this is now fixed.
553
554* aven: Add "hit test grid debug" mode, which shows the hit test grid and how
555  many entries are in each box (toggled by F3).
556
557* aven: Pressing F4 now allows the user to toggle wxWidgets assertion messages
558  off and back on.
559
560* aven: Create the empty hit-test grid data structure lazily, to reduce start
561  up time a little.
562
563* cavern: Improve messages which talk about "tags" and/or "prefixes" in *begin
564  and *end commands to instead talk about "survey names".
565
566* cavern: For ages cavern has warned if you reentered a survey, but this
567  warning was suppressed if it occurred at the same line of the same file as
568  the survey was first entered, but this can only happen if you include the
569  same survey file more than once, which isn't a sensible thing to do for a
570  file with actual survey data in (you might reasonably do it to set up survey
571  grade details or something like that).  The warning is now given in this
572  situation too.
573
574* cavern: After 5 warnings about reentering a survey we give up warning about
575  it, but we used to keep reporting where the survey was originally entered -
576  this secondary diagnostic message is now silenced when the main message is.
577
578* (Microsoft Windows version): Compile C code with optimisation on.
579
580* Add the start of a Russian translation, with messages take from therion.
581
582* Minor translation updates to French.
583
584* Fix compiler warning from GCC.
585
586* Testsuite improvements:
587
588  + Test that "..." anon station works.
589
590  + cavern.tst: Check number of errors returned by all testcases which should
591    fail and give an error count.
592
593  + cavern.tst: Fix to actually fully test everything when builddir != srcdir.
594
[ad727d8]595Changes in 1.2.12 (2014-04-14):
[46d12e9]596
[63e8642]597* aven: Fix measuring line to show change in altitude rather than altitude
598  itself (accidentally broken by changes in 1.2.11).  Reported by Brian
599  Clipstone.
[46d12e9]600
[ad727d8]601* aven: Fix printing when built with wxWidgets 3.0.
602
603* aven: Several visual improvements to printouts:
604
605  + Move the numbers below the scale bar down a little so that they don't
606    overlap the scale bar ticks.
607
608  + Set the clipping region after we draw the page border and info box to avoid
609    clipping the border in print preview.
610
611  + Tidy up the appearance of the compass and elevation arrow.
612
[63e8642]613* aven: Fix to build with libav 10.  Reported by Moritz Muehlenhoff in
614  <http://bugs.debian.org/739332>.
[46d12e9]615
[63e8642]616* aven: Fix to build with older libav where avcodec_free_frame() isn't
617  available.
[46d12e9]618
[ad727d8]619* (Linux version) survex.spec: Update spec file used for building RPM packages.
620
621* (Unix version): Add "Keywords:" entry to .desktop files.
622
623* (Unix version): Enable large file support, mostly to support filing systems
624  which return 64 bit inode values, such as CIFS mounts.
625
[63e8642]626* (Microsoft Windows version): Only allow "A-Z" or "a-z" for driver letters,
627  rather than any character which is a letter in the current locale.
[46d12e9]628
[63e8642]629* Various translation updates.
[46d12e9]630
[aac3336]631Changes in 1.2.11 (2014-01-28):
[fb941bfd]632
633* aven: Fix wxWidgets assertion when double clicking on an anonymous station.
634  Reported by Kevin Dixon.
635
[aac3336]636* aven: Embed the font data for the first 256 Unicode characters for use in the
637  survey pane into the compiled aven binary to reduce start up overhead.  Any
638  additional characters needed are loaded from a data file only if/when a
639  character >= U+100 is actually needed (as before).
640
[ad3017d]641* aven: Fix display of Unicode characters above 256 when there's a character
642  <= 256 earlier in the same string.
643
[77bdacf]644* aven: Use the actual width of Unicode characters above 256 rather than
645  assuming they are 16 pixels wide.
[ad3017d]646
647* aven: If full screen, don't show the side panel when a new file is opened
648  (e.g. via Ctrl+O).
649
650* aven: Don't give an assertion failure when showing passages for a cave with
651  no vertical extent.  Reported by Jonny Prouty.
652
653* aven: Change terminology in print dialog - say "legend" instead of "info
654  box".
655
656* aven: Add option to show the tilt angle as a percentage gradient.
657
658* aven: Show the units (degrees, grads, or percent) for the tilt and bearing
659  indicators.
660
661* aven: All length units are now translatable.
662
[fb941bfd]663* aven: Split log_fl_error helper function out of CHECK_GL_ERROR macro, which
664  will reduce code size and also the number of deprecation warnings about
665  gluErrorString on Mac OS X 10.9.
666
[ad3017d]667* (Microsoft Windows version): aven: Try to work around redraw issues related
668  to the measuring line by redrawing the whole window, which doesn't seem to be
669  measurably slower.
670
671* cavern: If *units is used to try to set units for LEVEL, PLUMB, or POSITION,
672  give an error rather than quietly ignoring the attempt.
673
[77bdacf]674* cad3d: Make cad3d remap control characters and spaces in station names when
675  generating PLT output in the same way aven does.
676
[ad3017d]677* Various translation updates (particular thanks to Eric Madelaine and Dennis
678  Baudys), including the start of a Bulgarian translation, with messages taken
679  from Therion and elsewhere.
680
681* (Microsoft Windows version): On Microsoft Windows 2000 and newer, use
682  GetUserDefaultUILanguage() to get the UI language to use.  For older
683  versions, continue to use GetUserDefaultLCID().
[fb941bfd]684
685* (Microsoft Windows version): The Indonesian translation will now be used
686  automatically when the system language is set to Indonesian.
687
688* (Mac OS X version): Fix to build with wx 3.0.0 on OS X 10.9.  Thanks to David
689  A. Riggs for his work on this.
690
691* (Mac OS X version): Update buildmacosx.sh script to use wx 3.0.0, and add a
692  checksum check for the downloaded wx sources.
693
694* Fix a lot of the compiler warnings when building with clang.
695
[ad3017d]696* doc/manual.sgml: Add missing quantities to the list documented as accepted by
697  *units: LEFT, RIGHT, UP/CEILING, DOWN/FLOOR (missing entirely);
698  BACKCOMPASS/BACKBEARING, BACKCLINO/BACKGRADIENT (missing from the main list,
699  mentioned in list of the units that can be set for them); COUNT (missing
700  alternative name for COUNTER); DX/EASTING, DY/NORTHING, DZ/ALTITUDE
701  (incorrectly listed as X, Y, Z).  Reported by Jonny Prouty.
702
703* Test suite: Improve test coverage for cavern.
704
[0ecf3b1]705Changes in 1.2.10 (2014-01-15):
706
707* aven: Fix assertion if two mouse buttons are held down at the same time.
708  If dragging with more than one mouse button held down, releasing one causes
709  another which is still held down to take effect.  Reported by Brian
710  Clipstone.
711
[53966d3]712* aven: If we fail to start the external editor when the user clicks on an
713  error or warning from cavern, show an error box.
714
[6f0d0d8]715* aven: If the survey has a title, add it as a top-level <title> element to
716  exported SVG files.
717
718* aven: Escape '<', '>', and '&' in labels in exported SVG files.
719
720* aven: In GPX export, set the <time> element to the datestamp from the 3d
721  file.
722
723* aven: Don't try to write the title if it isn't set or is empty when exporting
724  GPX files.
725
726* aven: Don't bother looking up the printer page setup info when exporting.
727
[0ecf3b1]728* (Microsoft Windows version): aven: Fix crash on "File->Print" or
729  "File->Export" under Windows XP, reported by Brian Clipstone.
730
731* (Microsoft Windows version): aven: Fix error dialog about an incorrectly
732  encoded filename which could occur if run without being asked to load a file
733  on startup.
734
735* (Microsoft Windows version): aven: Compile with optimisation on.
736
737* img library, aven: Although processed CMAP data files are often referred to
738  as "CMAP .XYZ files", it seems that actually, the extension .XYZ isn't used,
739  rather .SHT (shot variant, produced by CMAP v16 and later), .UNA (unadjusted)
740  and .ADJ (adjusted) extensions are.  Since we've long checked for .XYZ, we
741  continue to do so in case anyone is relying on it, but also check for the
742  other extensions.
743
744* img library: Add new "datestamp_numeric" field to struct img giving the
745  datestamp as a time_t in UTC (or (time_t)-1 if there's no datestamp or we
746  failed to convert it).  For .3d >= v8, this field is reliable.  We attempt to
747  convert date strings in .3d <= v7 and CMAP XYZ files, but may get the
748  timezone wrong.
749
750* img library: Fix my_strcasecmp() to handle top-bit set characters better.
751
[6f0d0d8]752* cavern: Fix NULL pointer dereference when processing Compass DAT file without
753  'SURVEY DATE:'.
[0ecf3b1]754
[6f0d0d8]755* doc/manual.sgml: Update references to Survex 1.1 which should be to 1.2.
[0ecf3b1]756
[6f0d0d8]757* doc/manual.sgml: Note the station length limit Smaps used.
[0ecf3b1]758
[53966d3]759* Fix some compiler warnings if built with glibc's fortify source feature
760  enabled.
761
[6b6fb4d]762Changes in 1.2.9 (2014-01-08):
763
764* Document --3d-version in cavern man page and the manual.
765
766* aven: Fix compilation error in movie export code with recent libavi.
767
768* aven: Fix warning on stderr when export a movie as MPEG.
769
770* img library: In non-hosted mode, don't define GETC and PUTC if they're
771  already defined, to allow easy overriding with getc_unlocked() and
772  putc_unlocked() (which are significantly faster on Linux).
773
774* img library: In non-hosted mode, check that int is at least 32 bits,
775  and if not, use long.  In practice, platforms with 16 bit int are mostly
776  obsolete, but it's not hard to be portable here.
777
778* img library: Add test that img.c and img.h compile in non-hosted mode
779  (regression test for issue fixed in 1.2.8).
780
781* (Microsoft Windows version): aven is now built with wxWidgets 3.0.0.
782
783* Update translations from launchpad and from existing similar messages.
784
785* Fix some compiler warnings.
786
[e1f27c4]787Changes in 1.2.8 (2013-10-29):
[da65891]788
789* cavern: Fix handling of anonymous wall stations ('..' by default) to
790  implicitly set the SPLAY leg flag, as was intended.  Reported by Thomas
791  Holder.
792
[e1f27c4]793* cavern: Tweak .err file output not to lose the space in front of certain
[034141d]794  statistics when the value gets large.
795
[a4adf09]796* cavern: Eliminate redundant progress message when solving simultaneous
797  equations.
798
[e1f27c4]799* aven: Add a format drop down to the export dialog, and only show fields which
800  are meaningful and supported for the currently selected export format.  The
801  format defaults to that used most recently.  The "Elements" and "View" boxes
802  have been swapped in the print and export dialogs as that layout works much
803  better when the "View" box is hidden.
804
[0056ee1]805* aven: Changing checkboxes in the print or export dialog didn't work in 1.2.7
806  - now works again.  Reported by Anthony Day.
807
[e1f27c4]808* aven: Add GPX export (based on findentrances patch from Olaf Kähler).  In
809  this release the projection which the survey coordinates are in defaults
810  to the BMN M31 grid used in the Totes Gebirge in Austria.  On Unix, you
811  can edit ~/.aven and add a new line setting 'input_projection' to a PROJ
812  projection string.  The ability to specify this projection in a better
813  way is coming soon.
814
815* aven: New export options "Origin in centre" and "Full coordinates" - the
816  latter fixes #10.  GPX and PLT output implicitly force "full coordinates".
817
818* aven: The "Sketch" vector drawing program got renamed to "Skencil" some
819  time ago, so update references.
820
821* aven: Make the Presentation->Play menu item a checkbox, to avoid a warning
822  with wxMSW 2.9.5.  Reported by Brian Clipstone.
823
824* aven: Make right click in an empty presentation mark the current position and
825  open it to edit, instead of crashing.
826
827* aven: Update movie export code to work with latest libav API.  Reported by
828  Sebastian Ramacher.
829
830* aven: Improve reporting of errors during the process of exporting a movie.
831
832* aven: Don't try to close the movie if we aren't producing one.
833
834* aven: Fix assertion failure when double-clicking on the survey with wx2.9.
835
836* aven: Fix to build with wxMSW 2.9.5.
837
838* aven: Fix to build with wx 2.9.5 with wx2.8 compatibility disabled.
839
840* cad3d: The "Sketch" vector drawing program got renamed to "Skencil" some time
841  ago, so add a new --skencil option to specify this output format.  The old
842  name (--sketch) is still recognised for compatibility.
843
844* cad3d: Make --marker-size work for Skencil and SVG output.
845
846* dump3d: Make --show-dates option show dates for XSECT.
[9fc1cac]847
[88b54df6]848* img library:
849
[e1f27c4]850  + Fix to work once more when used outside of Survex (missing definition of
851    max() macro and a bad call to free() in img_close() for a file opened for
852    reading).
853
854  + Use lround() instead of round(), and make the tests around whether we use
855    the library function or the our fallback implementation saner.
856
857  + Fix // comments in C code for portability to pre-C99 compilers which don't
858    support these as an extension.
[88b54df6]859
[f807d8bf]860  + Can now be compiled as C++ as well as as C.
861
[e1f27c4]862* (Microsoft Windows version): The installer is now built with a newer version
863  of Innosetup, and includes translations for all the languages which Survex
864  itself has any translations for.
865
866* (Microsoft Windows version): aven is now built with wxWidgets 2.9.5.
867
868* Minor translation updates.
869
870* tests/Makefile.am: Distribute files for "normal_bad" testcase.
871
[e34bebc]872Changes in 1.2.7 (2013-07-27):
[65d9b6b]873
[e34bebc]874* Add support for anonymous stations, which are indicated by one, two or three
875  separator characters - with the default separator of '.', that means '.',
876  '..', and '...' are anonymous stations.  Single separator ('.' by default)
877  is an anonymous non-wall point, double separator ('..' by default)
878  is an anoymous wall point at the end of an implicit splay), and triple
879  separator ('...' by default) is an anoymous point (with nothing special about
880  the leg).  A new *alias command allows '-' to be mapped to '..' for
881  compatibility with pocket topo: *alias station - ..
[07beaa4]882
[e34bebc]883* New version 8 of the 3d format:
[07beaa4]884
[e34bebc]885  + Supports new flags img_SFLAG_ANON and img_SFLAG_WALL.
[07beaa4]886
[e34bebc]887  + New explicit file-wide flag for 'this is an extended elevation', rather
888    than modifying the survey title to indicate this.
[da9d788]889
[e34bebc]890  + The survey prefix is often unchanged from one leg to the next, so use a
891    spare flag to compactly indicate when there's no label change.
[da9d788]892
[e34bebc]893  + The data style of each leg is now stored.
[da9d788]894
[e34bebc]895  + The "processed at" time is stored as seconds since 1970 rather than a
896    human-readable string.
[da9d788]897
[e34bebc]898  + Since 3d v8 features significant changes to the format, the format
899    documentation for v7 and earlier has been split off into 3dformat-old.htm.
[da9d788]900
[e34bebc]901* img library:
[da9d788]902
[e34bebc]903  + New station flags img_SFLAG_ANON and img_SFLAG_WALL.
[da9d788]904
[e34bebc]905  + Handle .pos files containing unnamed stations - don't suck the next line in
906    as the station name, and set img_SFLAG_ANON for them.
[da9d788]907
[e34bebc]908  + Repurpose the long unused fBinary parameter to img_open_write() as a flags
909    parameter, and add img_FFLAG_EXTENDED to specify that this is an extended
910    elevation, in place of appending " (extended)" to the title.  Internally we
911    still append this to the title (and remove it upon reading) when writing
912    3d v7 or earlier, but for the new 3d v8 format, this flag is stored
913    explicitly in the file.
[da9d788]914
[e34bebc]915  + img.h: Add comments for the lists of "Leg flags" and "Station flags".
[da9d788]916
[e34bebc]917* aven:
[da9d788]918
[e34bebc]919  + We now require at least wxWidgets 2.8.0 - it was released over 6 years ago
920    now, and the wx developers consider even 2.8 to be rather long in the
921    tooth.  We stopped testing building with wxWidgets 2.6 some time ago, and
922    formally dropping support for older versions allows a number of workarounds
923    to be removed from the aven source code.  Also, features deprecated in
924    wxWidgets 2.9 are no longer used in our code.
[da9d788]925
[e34bebc]926  + Don't run incremental search on every key-press, as on a slow machine the
927    short initial search(es) will take a while but not be useful.  Instead only
928    actually run the search when we're told there are no more key-presses
929    queued up.
[da9d788]930
[e34bebc]931  + Implement support for including cross-section information in exported SVG
932    and DXF files (ticket#4).  The DXF export is untested currently.
933
934  + Show splay legs faded by default, with menu options to hide them or show
935    them like other legs.
936
937  + Speed up loading a .3d file with cross-sections by using a map to convert
938    station names to positions.
939
940  + In the cavern log window, don't highlight a file:linenumber if there's no
941    message after it, which avoids highlighting the "Included from" lines
942    wrongly.
943
944  + Fix not to crash when trying to report an error while starting up.
945
946  + (MacOS X version): Change the menu shortcut for "Full Screen Mode" to be
947    the OS X standard shortcut Shift-Command-F (previously we used F11, but
948    that's used by the desktop).
949
950  + Add checks for errors when reading the font file.
[07beaa4]951
[e34bebc]952  + Remove useless extra quoting when invoking vim to show the location of an
953    error from cavern.
[07beaa4]954
[e34bebc]955  + Include GL/gl.h before GL/glext.h (needed on Debian wheezy).
[da9d788]956
[e34bebc]957  + Use wxValidator to simplify keeping svxPrintDlg member variables and fields
958    in the dialog in sync.
[da9d788]959
[e34bebc]960* cavern:
[3dfffa2]961
[e34bebc]962  + Demote errors about invalid dates to warnings, since we've accepted *date
963    for ages without any checks on the value, and so existing datasets
964    probably contain invalid dates and dates in other formats.  (ticket#19)
[3dfffa2]965
[e34bebc]966  + New *alias command allows '-' to be mapped to '..' for compatibility with
967    pocket topo: *alias station - ..
[07beaa4]968
[e34bebc]969  + We want to warn if there's a clino reading which it would be impossible to
970    have read from the instrument (e.g. on a -90 to 90 degree scale you can't
971    read "93" (it's probably a typo e.g. for "39").  However, the gradient
972    reading from a topofil is typically in the range 0 to 180, with 90 being
973    horizontal.  Really we should allow the valid range to be explicitly
974    specified, but for now we infer it from the zero error - if this is within
975    45 degrees of 90 then we assume the instrument can read between 0 and 180
976    degrees.
[da9d788]977
[e34bebc]978  + If the survey isn't all connected, still run survey tree checks and report
979    errors and/or warnings which might suggest typo locations.  Thanks to Kevin
980    Dixon for the report which highlighted this issue.
[da9d788]981
[e34bebc]982  + Report a warning if *begin SURVEY has a separator character in SURVEY.
[da9d788]983
[e34bebc]984  + Report column numbers as well as line numbers for some cavern errors and
985    warnings.
[07beaa4]986
[e34bebc]987  + Adjust width of node stats table to fit longest count when there are more
988    than 9999 of a particular order of node.
[07beaa4]989
[e34bebc]990  + If the argument to *include has an opening double quote but the closing
991    double quote is missing, then skip trying to open the file.
[da9d788]992
[e34bebc]993  + Move "Station X referred to just once" warning after non-existent survey
994    check - if both fire, the non-existent survey error is likely to be more
995    relevant.
[da9d788]996
[e34bebc]997  + We no longer follow an error for a bad reading in passage data with a bogus
998    "End of line not blank" error, but instead check the remaining readings on
999    the same line.
[da9d788]1000
[e34bebc]1001  + We no longer follow an error about OMIT for a required reading with a bogus
1002    "End of line not blank" error.
[7f6250a]1003
[e34bebc]1004  + Report an error if the scale factor in *calibrate is zero - it doesn't make
1005    sense and probably means someone reversed the arguments to *calibrate.
[3dfffa2]1006
[e34bebc]1007  + Report the parent include files starting from the outermost, as that's more
1008    logical when there are multiple levels involved.
[07beaa4]1009
[e34bebc]1010  + If we were expecting a numeric field and instead get something which starts
1011    with '+', '-', or '.' but which isn't a number, then fix the error to
1012    include that character in the token reported.
[3dfffa2]1013
[e34bebc]1014  + Simplify handling of quantity lists to only recognise 'DEFAULT' as the
1015    first item.
[07beaa4]1016
[e34bebc]1017* cad3d: Check for errors from img_rewind() and report them.
[07beaa4]1018
[e34bebc]1019* dump3d:
[07beaa4]1020
[e34bebc]1021  + Build, install and package dump3d as standard - it's useful for grabbing
1022    info from 3d files in scripts.
[07beaa4]1023
[e34bebc]1024  + Add --show-dates option.
[07beaa4]1025
[e34bebc]1026  + Show only 2 decimal places on coordinates and passage dimensions.
[07beaa4]1027
[e34bebc]1028  + Report the data style of legs.
[da9d788]1029
[e34bebc]1030  + Report if the file is an extended elevation.
1031
1032  + Report img_STOP as STOP rather than CODE_0xffffffff.
[3dfffa2]1033
1034* Test suite:
1035
1036  + cavern.tst: Fix equatenosuchstn testcase (added in 1.2.6) to normalise the
1037    expected output so it passes reliably.
1038
[e34bebc]1039  + cavern.tst: Run diffpos <expected> <actual> so the reports of 'Added' and
1040    'Deleted' stations upon failure are the more natural way round.
1041
[07beaa4]1042  + Add more testcases, expand some existing testcases, and add expected output
1043    for more.
1044
[e34bebc]1045* (Microsoft Windows version): Use wx-config's --cc and --cxx flags to find the
1046  appropriate C and C++ compilers to use, and link mingw build statically to
1047  avoid needing the libgcc DLL (which newer GCC seems to have by default).
[3dfffa2]1048
1049* (Unix version): When determining the character set for command-line tools,
1050  check environmental variable LANG after LC_ALL and LC_CTYPE.
1051
1052* When determining the language, check environmental variable LC_ALL before
1053  LC_MESSAGES and LANG (but after SURVEXLANG).
1054
[e34bebc]1055* If we don't find the message file, only give an error if it was specified
[665183c]1056  with SURVEXLANG, since that is an explicit instruction to Survex, whereas
[e34bebc]1057  LANG, LC_ALL and LC_MESSAGES are essentially system "preferred locale"
1058  settings.
1059
1060* There are a handful of hard-coded English message strings for reporting
1061  errors trying loading message files, etc.  These are all now ASCII, as if we
1062  fail trying to open a message file, it's more likely the encoding isn't
1063  set correctly.
1064
1065* Prune strings we are no longer using and are probably unlikely to use again
1066  into a new file po_codes_dead, so that translators don't get presented with
1067  them to translate.
1068
[07beaa4]1069* Merge lots of translation updates.  Most translations are now complete or
1070  close to complete.
[3dfffa2]1071
1072* Add start of Indonesian translation from Arief Setiadi Wibowo.
1073
[07beaa4]1074* Fix various compiler warnings when building from source.
1075
[e34bebc]1076* Include scripts gdtconvert and gen_img2aven in the source distribution.
1077
[c575465]1078Changes in 1.2.6 (2012-02-23):
[b081031]1079
1080* (Mac OS X version): Fix so that cavern finds its messages when run by aven.
1081
1082* (Microsoft Windows version): Include JPEG images for aven in the installer
1083  package (ticket#35).
1084
1085* cavern: If we have a reference to a station in a non-existent survey, give a
1086  helpful error rather than saying the station hasn't been exported from the
1087  survey.  (Bug reported by Martin Green via email)
1088
1089* aven: Fix to build with a non-Unicode wxWidgets library.  Patch from Olaf
1090  Kahler.
1091
1092* findentrances: Add findentrances utility from Olaf Kahler which produces a
[c575465]1093  .gpx file with waypoints for entrances.  This needs libproj so is disabled
1094  by default for this release - to enable it install the development stuff for
1095  libproj and build survex with:
1096
1097      make FINDENTRANCES=findentrances
1098      make install FINDENTRANCES=findentrances
[b081031]1099
1100* dump3d: Add support for showing img_ERROR_INFO items.
1101
1102* doc/3dformat.htm: Merge in some improvements from Mike McCombe.
1103
1104* Incorporate a French translation from launchpad I'd previously copied the
1105  English version of by mistake.  Attempt to correct mistranslation of "survey
1106  file".
1107
[685116f]1108Changes in 1.2.5 (2012-01-03):
1109
1110* aven:
1111
1112  + The survey tree in the left panel is now in sorted order once more.
1113
1114  + No longer fails with an assertion if used for a long time (we were leaking
1115    an OpenGL list each time one had to be regenerated).
1116
1117  + Now builds with newer FFmpeg library.
1118
1119  + Draw measuring line in front of the indicators rather than behind them.
1120
1121  + Loading a new file (or reloading the current one) no longer invalidates
1122    the OpenGL lists for the compass and clino, so will be a fraction faster.
1123
1124* Improve handling of attempts to look up translated messages before the
1125  message subsystem is fully initialised (which only happens if there's an
1126  error early on).
1127
1128* Improve the survex(7) man page text, and fix it to be marked as section 7 in
1129  the man page source as well as in the filename.
1130
[f15ca67f]1131Changes in 1.2.4 (2012-01-01):
1132
1133* aven:
1134
1135  + A change in 1.2.3 meant that aven tried to use OpenGL before it was
1136    initialised, which doesn't cause problems in some machines, but causes aven
1137    to abort on others.  This is now fixed, and there's a check in place to
1138    help avoid similar issues in future. (ticket#34)
1139
1140  + Always use metres or feet for the depth colour key, and chose a consistent
1141    precision by looking at the depth range. (ticket#30)
1142
1143  + Show the depth units below the colour bar rather than after every value.
1144
1145  + When zooming way in, stay in metres rather than switching to cm.
1146
1147  + On the scale bar, say “1 mile” rather than “1 miles”.
1148
1149* Translation updates for Catalan, French and Slovak.
1150
[5b9942e]1151Changes in 1.2.3 (2011-12-31):
1152
1153* Fix to build with wxWidgets 2.9.2.
1154
1155* (Mac OS X version):
1156
1157  + Processing .svx files from aven now works.
1158
1159  + Remove spurious blank lines from the licence text in "Get Info".
1160
1161  + Don't create the help menu at all, as it is empty (because the "About"
1162    entry goes elsewhere) and sometimes seems to appear in the UI.
1163
1164  + INSTALL.OSX: Update to reflect current status.
1165
1166* aven:
1167
1168  + Fix Y coordinates of surface surveys on printouts.  (Closes #32)
1169
1170  + Improvements to text plotted on the survey pane:
1171
1172    - Support plotting Unicode character points > 256 by lazily loading the
1173      data for them from the font file and plotting them with a direct call to
1174      glBitmap(), which is slower but doesn't require a display list per
1175      character.
1176
1177    - Adjust the spacing from fixed width to putting a one pixel gap either
1178      side of each one character (so two between adjacent glyphs).  Mostly this
1179      reduces the horizontal width, but it adds a pixel for characters like "m"
1180      and two in a few cases.
1181
1182    - Fix .pixelfont file generation to correctly handle characters wider than
1183      8 pixels.
1184
1185  + Fix expected cross shape so don't always reject using texture mapping to
1186    draw crosses.
1187
[3ea0178]1188  + As we read a survey file, eliminate tubes consisting of zero XSECTs as well
1189    as those consisting of just one.  Previously we would trip over the empty
1190    tube later.  Such tubes can for example be created by extend if a splay shot
1191    is the start or end of a tube.
1192
[5b9942e]1193  + Make the green colour used for entrances in the survey tree the same
1194    (slightly darker than before) green used for the entrance blobs.
1195
1196  + Report the version of the library we're actually running with if built
1197    against wx >= 2.9.2.  Make it clear that the version reported is the
1198    version *built* with for wx < 2.9.2.
1199
[3ea0178]1200* extend:
1201
1202  + Copy the end markers for passage tubes.
[5b9942e]1203
[3ea0178]1204  + Preserve left and right data for tubes (previously they were set to -1.0
1205    which means "no info").
1206
1207* img library: Fix incorrect comment in img.h which claimed that img_XFLAG_END
1208  was no longer used - it certainly is!
1209
1210* Use curly double quotes instead of "`" and "'" to quote filenames, etc in
1211  messages, and curly single right quote instead of straight ASCII apostrophe.
1212  Fall back to using straight ASCII versions if we can't represent them in the
1213  current character set.
[5b9942e]1214
[3ea0178]1215* Translation updates for Catalan, French, Slovak and Spanish.
[5b9942e]1216
1217* Test suite:
1218
1219  + Add test coverage for interleaved diving data.
1220
1221  + Add testcase for diving data with topofil-style distance.
1222
[94960ad]1223Changes in 1.2.2 (2011-10-06):
1224
1225* aven:
1226
1227  + Replace the textured-mapped font drawing with an approach based on
1228    glBitmap.  This doesn't suffer from the character alignment issues which
1229    the textured-mapped fonts had, and is actually significantly faster on some
1230    machines.  The current font used is (mostly) fixed-width, but this isn't an
1231    inherent limitation - it was just the easiest font data to convert to a
1232    usable format.
1233
1234  + Fix assertion failure due to rounding differences on loading certain .3d
1235    files.  (ticket#26)
1236
1237  + Fix assertion failure when turning on 3D passages if they stick out higher
1238    or lower than any station.  (ticket#29)
1239
[53f8a93]1240  + Fix grid not to disappear when blobs are turned on and blobs are drawn
1241    using lines.
1242
[94960ad]1243  + If a degree sign isn't available in the character set in use, transliterate
1244    it to 'dg' rather than skipping it.
1245
1246  + Fix message which should have been a degree sign but got lost in the format
1247    change for 1.2.0 and then got reassigned in 1.2.1.  Externally, this means
1248    that bearings in the status bar now have a degree sign after them if they
1249    are in degrees rather than nothing (1.2.0) or "&Hide Compass" (1.2.1).
1250
1251  + Fix print dialog to calculate the scale required for "One page" right
1252    before it calculates how many pages are required, so we don't end up
1253    something other than 1x1 being shown when the user changes settings.
1254
1255  + Update the calculations for picking a scale and for deciding how many
1256    pages are needed to take into account the change in info box height made
1257    in 1.2.1.
1258
[9704252]1259Changes in 1.2.1 (2011-10-04):
[e3c58c3]1260
1261* Translation updates for US English.
1262
1263* aven:
1264
1265  + Rename the "depth bar" to "colour key" in documentation, menus, etc since
1266    it now shows colours for dates and errors as well as depths.
1267
1268  + In the colour key for "colour by date", change "No info" to "Undated".
1269
1270  + Remove the dark grey background from the colour key and just put a single
1271    pixel black border around the colours.  This is more in keeping with the
1272    other controls, and means the colours are now on a black background so more
1273    visually similar to the survey legs.
1274
1275  + Move the colour key's "Undated"/"Not in loop" entry down a little to
1276    improve the appearance.  Make each section a pixel taller.
1277
[9704252]1278  + Allow "Colour by X" to be selected even if there's no data for X or only a
1279    single value of X used (the colour key is much smaller in these cases, and
1280    does still provide some useful information).
1281
1282  + Fix incorrect calculation of depth colouring for survey legs which straddle
1283    a depth band boundary.
[e3c58c3]1284
1285  + The scale bar, compass, clino, and colour key now all have right click
[9704252]1286    menus which allow related actions to be performed (especially handy in
1287    full-screen mode).
[e3c58c3]1288
1289  + Improve the font used on the survey pane - it now contains the '-'
1290    character (so the clino now shows negative angles as negative, and dates
1291    in the colour key are now hyphenated).  Also the spacing and alignment
1292    are a little better, though still not perfect.
1293
1294  + PLT file export now handles spaces and control characters in station names
1295    by escaping them with '%' as in URLs.
1296
1297  + Pressing "Enter" on a station in the tree control now centres the view on
1298    that station.
1299
1300  + The scale bar is now cached in an OpenGL display list since it often gets
1301    redrawn exactly the same - for example, when rotating, panning, etc.
1302
1303  + Pressing "F5" forces all cached OpenGL drawing lists to be invalidated and
1304    then forces a refresh of the survey pane.  This is intended as a debugging
1305    aid - if pressing F5 changes the display at all then there's a missing case
[9704252]1306    where a list should have been invalidated (please report if you find such
1307    a case as it is a bug).
[e3c58c3]1308
[9704252]1309  + We now automatically track which OpenGL display lists need to be
1310    invalidated on window width or height changes.
[e3c58c3]1311
1312  + Increase scale bar maximum width from 65% of the window width to 75% as it
1313    was in 1.0.x (except that if that would overlap the clino we now reduce
1314    that proportion down until it reaches 50%).  Make the limit of zooming in
1315    the same as in 1.0.x.  (ticket#23)
1316
[9704252]1317  + (Linux version): Previously wxGTK didn't really handle showing a dialog if
1318    the application was fullscreen (the dialog got opened under the main
1319    window!)  To work around this, aven would switch out of full screen mode
1320    temporarily while showing a dialog.  This case works properly with recent
1321    wxGTK, so disable our workaround with versions we know work.  Also, apply
1322    the workaround only for wxGTK, not everywhere except on Microsoft Windows
1323    as there's no reason to think we need it for other platforms.
[e3c58c3]1324
1325  + Grey out the "View North" action when we're already viewing North, and
1326    similarly for other compass points.
1327
1328  + (Mac OS X and Microsoft Windows versions): Fix missing newline to OpenGL
1329    info in the "About" dialog.
1330
1331  + Fix to set the correct filename on the root of the survey tree - previously
1332    the filename of the previous file loaded was used!
1333
1334  + The movie export code now works with newer versions of the FFmpeg libraries
1335    as well as still working with older versions.
1336
1337  + Fix mixed up messages - the print dialog now says "View" on the left
1338    subgroup of controls rather than some unrelated message.
1339
1340  + On printouts, combine the "Plan View"/"Elevation" info box field with the
1341    field which gives the bearing and reduce the height on the info box by the
1342    removed field, so it's now 3cm for plans and elevations, as for extended
1343    elevations.  Report the tilt angle for tilted elevations which it seems has
1344    been missing for ages (it's not in recent 1.0.x either).
1345
1346  + Tweak the exact positioning of informational text on printouts to look
1347    nicer and make better use of the available space.
1348
1349  + Add keyboard mnemonics to the "Plan" and "Elevation" buttons in the print
1350    dialog.
1351
1352  + Make the sign of the tilt angle for printouts consistent with the sign
1353    shown by the "clino" in the survey pane.
1354
1355  + In the "Print" dialog, when in plan view disable the "Plan view" button,
1356    and similarly for the "Elevation" button.
1357
[9704252]1358  + (Microsoft Windows version): Sort out appearance of custom cursors.
1359
[e3c58c3]1360  + If a label isn't valid UTF-8 or CP1252, fall back to ISO8859-1.
1361
1362  + (Mac OS X version): F11 puts aven into full screen mode, but apparently
1363    you can't get out again easily, so add code to explicitly check for F11
1364    being pressed and toggle full screen.
1365
1366* (Linux version): Fix the RPM .spec file for where man pages now get installed
1367  and package aven.svg and the vim support files.  (Fixes from James Begley)
1368
1369* "make check" now performs several checks on the translation files.
1370
1371* More messages are now available to be translated.
1372
1373* cavern: Fix reporting of ranges of survey coordinates, which was broken by
1374  the message handling changes in 1.2.0.
1375
1376* Fix warning when compiling with GCC.
1377
1378* INSTALL: Mention building wxWidgets with --enable-unicode.  Mention using
1379  sudo for installing on Unix.
1380
1381* In the manual, replace the instructions for building from source with a
1382  pointer to the clearer instructions in INSTALL.
1383
1384* In the manual, make it clear that installing with administrator rights
1385  also applies to newer platforms than XP.
1386
1387* doc/TODO.htm: Update.
1388
[120c1c6]1389Changes in 1.2.0 (2011-09-20):
[b4ac7007]1390
1391* Translation updates for Catalan, French, Romanian, Spanish, Slovak, and US
1392  English.
1393
[9cfcb3f]1394* tests/smoke.tst: aven no longer requires an X display for --help or
1395  --version, so replace skip of this check with a check that this remains the
1396  case.
1397
1398* We now use the standard .po and .pot file formats for storing translations
1399  (rather than the Survex-specific messages.txt format), and then translate
1400  these into Survex's .msg format.
1401
[b4ac7007]1402* (Unix version): Move survex man page to section 7 (since it isn't documenting
1403  an actual command).
1404
[9cfcb3f]1405* (Unix version): Write each generated man page to a temporary file, then
1406  atomically rename, to avoid leaving an empty or partial man page behind if
1407  docbook-to-man dies (1.1.16 had an empty cad3d.1, and we want to avoid a
1408  recurrence of that).
1409
[b4ac7007]1410* (Unix version): Default to installing docs into /usr/share/doc/survex rather
1411  than /usr/doc/survex.
1412
1413* aven:
1414
[120c1c6]1415  + Fix handling of accented characters in the survey pane.
1416
[9cfcb3f]1417  + Aven icon redrawn in SVG format - it's now a vector image which looks
1418    nicer at larger sizes.
1419
[b4ac7007]1420  + Explicitly request double-buffering, which seems to be needed for systems
1421    with GLX >= 1.3.
1422
1423  + Fix crash while trying to load certain .3d files.
1424
1425  + Movie export code updated to work with more recent versions of FFmpeg.
[4095cc0]1426    Currently this is disabled in Microsoft Windows builds, pending getting the
1427    required libraries set up for building releases.
[b4ac7007]1428
1429  + Reporting of errors during movie export improved.
1430
1431  + Force playback speed to "x1" during movie export.
1432
1433  + Use stock IDs for buttons where appropriate - such buttons may now be
1434    rendered with icons on some platforms.
1435
[9cfcb3f]1436  + If a label isn't valid UTF-8, treat it as CP1252 (the Microsoft superset of
1437    ISO8859-1).
1438
1439  + (Unix version): Remove special handling for toggling "full screen" on wxGTK
1440    as it's no longer required with modern versions.
1441
1442  + Don't redraw the survey on every mouse movement in the survey pane unless
1443    the measuring line is (or just was) active.  (ticket #17)
1444
[b4ac7007]1445* cavern:
1446
1447  + Drop "non-fatal" from the report of how many errors there were at the end
1448    of the run - it just confuses users - we won't even get here if there's a
1449    fatal error!
1450
[9cfcb3f]1451  + Add --3d-version option to allow the user to specify the version of the 3d
1452    format to output.  (ticket#21)
1453
1454* img library:
1455
1456  + Make the highest and lowest valid values for img_output_version available
1457    in img.h as IMG_VERSION_MIN and IMG_VERSION_MAX.
1458
[b4ac7007]1459* (Mac OS X version): Fix buildmacosx.sh script to check where the temporary
[120c1c6]1460  volume actually gets mounted.  Fix URL for downloading wxWidgets.
[b4ac7007]1461
[8f9b0b6d]1462Changes in 1.1.16 (2011-05-16):
[ecdb631]1463
1464* Translation updates for German, Spanish, Italian, Portuguese, Brazilian
1465  Portuguese, and US English.
1466
1467* Use horizontal ellipses character rather than '...' and right arrow character
[ec8fd0d]1468  rather than '->' where these characters are available.
[ecdb631]1469
1470* (Unix version): Link with -lGL, if it exists, to support linking with gold or
1471  GNU ld --as-needed (Debian bug #615781).
1472
1473* img.c:
1474
1475  + Fix code typo for IMG_API_VERSION == 0 case.
1476
1477  + Fix code typo in code used when IMG_HOSTED isn't defined.
1478
1479* doc/TODO.htm: Remove entries which have now been done.
1480
[8f9b0b6d]1481* (Microsoft Windows version): aven: We now include all the available
1482  translations for messages from wxWidgets, which means that standard widgets
1483  will appear translated where available even if Survex messages aren't
1484  translated.
1485
[f5e3521]1486Changes in 1.1.15 (2010-10-15):
[2d16e4e]1487
1488* aven:
1489
1490  + In the cavern log window, change the "Rerun" button to "Reprocess" to
1491    follow terminology in manual and elsewhere.  Fixes ticket#15.
1492
1493  + When displaying output from cavern, don't update the window after every
1494    line, but only when we don't have data from cavern pending.  Hopefully
1495    addresses ticket#12.
1496
1497  + If we aren't using GL_POINTS for blobs, draw them using a series of
1498    abutting lines rather than with gluDisk which is faster and gives a
1499    consistent shape.
1500
1501  + Check whether blobs and crosses actually render correctly as points/point
1502    sprites, and if they don't, fall back to drawing them with lines.  The
1503    best method is cached on disk, and rechecked automatically if the graphics
1504    hardware is changed or the drivers upgraded.
1505
1506  + Fix non-USE_FNT case to work again (it's limited to ISO-8859-1 characters
1507    though, so we still enable USE_FNT by default).
1508
1509  + Don't offer "All files" wildcard in presentation save dialog.
1510
1511  + (Microsoft Windows): Handle filenames with non-Latin1 characters in in
1512    more places.
1513
1514  + (Microsoft Windows): Quote filenames with spaces and metacharacters in
[f5e3521]1515    when running cavern from aven.  Fixes ticket#11.
1516
1517* editwrap: (Microsoft Windows): Handle filenames with non-Latin1 characters.
1518
1519* diffpos: Handle files with duplicate labels in better - extend generates
1520  duplicate labels when it breaks a loop.
1521
1522* Enable eswap-break testcase now that diffpos handles duplicate station names.
[2d16e4e]1523
1524* New v7 of .3d format which stores survey dates as number of days since
1525  January 1st 1900, so we now support dates from 1900-2078 (rather than
1526  1970-2037) with a smaller file size.  The img API is now versioned - you
1527  can select the new "version 1" by compiling with -DIMG_API_VERSION=1, which
1528  gives the survey dates in days in days1 and days2 instead of as time_t
1529  values in date1 and date2.  Fixes ticket#14.
1530
1531* Consistently use http://survex.com/ rather than http://www.survex.com/ - the
1532  former has been the canonical name for some time, with www.survex.com just
1533  redirecting to it.
1534
1535* (Unix version): Use unlocked file I/O if available, which can be much faster
1536  in some cases (we don't need the locking as we don't do multithreaded file
1537  I/O).
1538
1539* (Mac version): Fix compilation failure due to clash with Point in Mac OS X
1540  headers.
1541
1542* (Mac version): buildmacosx.sh now works again.
1543
1544* Most tests weren't actually running any testcases (looks like a sh
1545  portability issue).  This is now fixed, and fortunately all tests still pass.
1546
1547* Include the extra .isl translation files for Innosetup in the source archive.
1548
[f9473ab]1549Changes in 1.1.14 (2010-07-26):
1550
1551* Restore compatibility with wxWidgets 2.6 (1.1.13 required wxWidgets 2.8).
1552
1553* aven:
1554
1555  + After processing survey data, if there were warnings or errors, add a
1556    "Rerun" button to allow easy reprocessing after fixing problems.  If there
1557    were only warnings, also add an "OK" button to allow moving on to viewing
1558    the processed survey data (fixes ticket#13).
1559
1560  + Optimise updating of the cavern log window (hopefully fixes ticket#12).
1561
1562  + Fix links in cavern log window to link from exactly '<file>:<line>' (and
1563    not the ': ' after), and to make the title for the terminal the
1564    warning/error message.  Avoid false positives by checking that '<line>' is
1565    a number.
1566
1567  + Don't double escape the contents of href and target in links in the cavern
1568    log window.
1569
1570  + Improve handling of the splitter window, fixing behavioural glitches in
1571    various cases.
1572
1573  + Highlight stations matching any current search when a file is loaded.
1574    (ticket#9)
1575
1576  + (Mac version): Fix build issue due to Mac OS X polluting the global
1577    namespace with its own "Point" class.
1578
1579  + (Unix version): The Gnome print dialog has its own preview window so
1580    suppress ours if using the Gnome one.
1581
1582  + (Unix version): Link aven with -lGLU which SuSE Linux needs.
1583
1584  + (Microsoft Windows version): Fix handling of a double-click on the survey
1585    tree when built with wxWidgets >= 2.8.11.
1586
1587* cavern: Report relevant file and line number for three warnings which didn't
1588  give them before.
1589
1590* (Unix and Mac versions): configure: Update the wx-config probing code -
1591  wxmac-config etc aren't present with newer wxWidgets versions so there's no
1592  point looking for them now.
1593
1594* (Mac version): buildmacosx.sh: This script builds a diskimage with Survex in
1595  for easy installation.  Update it to work with the latest Survex versions
1596  (use WX_CONFIG not WXCONFIG; use a Unicode build of wxWidgets; if building a
1597  private wxWidgets, use 2.8.11 not 2.7.0-1).
1598
1599* manual:
1600
1601  + Correctly capitalise "GTK".
1602
1603  + Note that on Linux we only regularly test builds with the GTK+ version
1604    (change taken from 1.0).
1605
1606* Fixed the cad3d man page, which was an empty file in 1.1.13.
1607
[0bd49eb]1608Changes in 1.1.13 (2010-06-16):
[90d0d71]1609
1610* Say "wxWidgets" instead of "wxWindows" consistently.
1611
[739b92c]1612* img.c: Fix small memory leak (filename_opened member).
[90d0d71]1613
1614* cad3d, aven: Fix export to SVG when a label contains a '%' character.
[f1cbf74]1615
1616* aven:
1617
[90d0d71]1618  + wxWidgets 2.6.0 or newer is now required.
1619
1620  + A "Unicode" build of wxWidgets is now supported.  An "ANSI" build may still
1621    work but hasn't been tested recently (all packaged versions of wxWidgets
1622    seem to be Unicode now).
1623
1624  + Fix potential uses of uninitialised variables which may have been causing
1625    occasional glitches when loading a file on start-up.
1626
[e4bfd2f]1627  + Improvements to the handling of the font used for plotting labels and other
1628    text on the survey pane:
1629
1630    - Loading the font file is more efficient.
1631
1632    - Character spacing is improved.
1633
1634    - Default font is now anti-aliased.
[90d0d71]1635
1636  + "About" dialog:
1637
1638    - Add "Copy" button to copy the system info to the clipboard for easier
1639      bug reporting.
1640
1641    - List OpenGL extensions last, since there are usually lots of them with a
1642      modern gfx card.
1643
1644    - Fix 100% CPU usage while the "About" dialog is open.
1645
1646  + Processing .svx files:
1647
1648    - Passing a .svx file on the command line now works better.
[1324d6c]1649
[739b92c]1650    - Put the survey data log window in a splitter in the usual frame rather
1651      than opening a separate frame for it.
1652
[90d0d71]1653    - Auto-scroll the log window until we've reported a warning or error.
1654
1655    - Fix small memory leak.
1656
1657  + The presentation filename now defaults to using the basename of the
1658    currently loaded dataset, but we always prompt before we first save with
1659    such a name.
1660
1661  + Reduce memory usage when saving a screenshot.
1662
[e4bfd2f]1663  + Allow "Toggle Fullscreen" to work even if no survey is loaded now that we
1664    persist the window size (and maximised or fullscreen state) between
1665    invocations.
1666
[90d0d71]1667  + Fix reporting of OpenGL errors.
1668
1669  + Fix glitches when tilting while looking East.
1670
[739b92c]1671  + Added Portuguese and Slovak translations of wxWidgets messages.
1672
[90d0d71]1673* Documentation:
1674
[e4bfd2f]1675  + Rationalise manual formats - replace PostScript with PDF and drop RTF.
1676
1677  + Drop the "alternative manual formats" self-extracting zip file - people
1678    will generally just want one of the formats, so downloading several
1679    together isn't very useful.
1680
[90d0d71]1681  + 3dformat.htm: Update for v6 format (thanks to Mike McCombe).
1682
1683  + GPL.htm: Replace HTML version of licence with a link to the version on
1684    the FSF website.
1685
1686  + ChngeLog.htm: Stop generating an HTML version of the ChangeLog - it's too
1687    low level to be of interest to non-developers, and developers can look at
1688    the source code.
1689
1690* (Unix version): configure: New preferred name for specifying wx-config script
1691  is WX_CONFIG.  WXCONFIG still supported for compatibility.
[f1cbf74]1692
[e4bfd2f]1693* (Linux version): Source RPM package dropped as you can just build an RPM
1694  package from the source tarball.
1695
[739b92c]1696* (Microsoft Windows version): The installer is now created with a newer
1697  version of InnoSetup, which gives a 10% smaller download.
1698
[2e12f8c]1699Changes in 1.1.12 (2007-02-07):
[5940815]1700
1701* aven:
1702
[3db0798]1703  + Remember the window size or maximised/fullscreen state between invocations.
1704
[5940815]1705  + Add options dialog to "Export" similar to the one for "Print".
1706
[6b2113d]1707  + The "number of pages required" in the print dialog now updates when you
1708    change what is to be shown (underground legs/surface legs/station
1709    names/crosses).
1710
[920b066]1711Changes in 1.1.11 (2006-11-25):
1712
1713* Updated Czech, Spanish, and Slovak translations.
1714
[99d8798]1715* (MacOS X version): Assorted OS X specific tweaks and fixes.
1716
[920b066]1717* aven:
[78c67a6]1718
[920b066]1719  + Pick a smaller and clearer font for labels.
[99d8798]1720
[920b066]1721  + Fix character spacing.
[99d8798]1722
[920b066]1723  + Tweak display of bearing and elevation angles to look nicer with
1724    proportional fonts.
[99d8798]1725
[920b066]1726  + Use the title from the 3d (or plt, etc) file for the window title
1727    rather than the filename.
[99d8798]1728
[920b066]1729  + Show distances to 2 decimal places rather than the nearest integer.
[99d8798]1730
[920b066]1731  + Only consider underground legs when calculating the depth bands and
1732    depth colouring.
[99d8798]1733
[920b066]1734  + Add "Colour by Error".
[99d8798]1735
[920b066]1736  + Add entry for "white" in date and error keys.
[99d8798]1737
[920b066]1738  + When setting the view to a single point, don't change the scale.
[99d8798]1739
[920b066]1740  + If reloading the same file, don't change the view
[99d8798]1741
[920b066]1742  + Fix filetypes selector in open dialog.
[99d8798]1743
[920b066]1744  + Fix the charset we use for aven in certain cases.
[99d8798]1745
[920b066]1746  + Call msg_init before using msg_lang or it won't ever be set!
[99d8798]1747
[920b066]1748  + Pass wx the full language code to initialise the C library locale.
[99d8798]1749
[920b066]1750  + Fix bug in generating prefix tree view which could lead to a bogus
1751    leading dot on some survey names (bug probably introduced in 1.1.10).
[99d8798]1752
[920b066]1753  + "New Presentation" now ensures that the side panel is open
[99d8798]1754
[920b066]1755  + Fix updating of cached opengl lists when the view is reset to the
1756    default.
[99d8798]1757
[920b066]1758* Ignore LANG if it starts with a digit to avoid problems with bogus value for
1759  LANG which AutoCAD installation seems to set on MS Windows.
[99d8798]1760
[920b066]1761* (Unix version): configure: Allow SGMLTOOLS and DOCBOOK_TO_MAN to be
1762  specified.  Either/both can be set to ":".
[99d8798]1763
[920b066]1764* dump3d: Report unknown (to dump3d) codes returned by img.
[99d8798]1765
[920b066]1766* img library: Flag all stations as underground in the old "ASCII" .3d format.
[99d8798]1767
[920b066]1768Changes in 1.1.10 (2006-07-14):
[ac3f376]1769
1770* aven: Clicking on a survey name in the survey tree now highlights it in
1771  the map view.  Double-clicking zooms the view to show the clicked survey
1772  highlighted.  Clicking the root clears the highlighting and double-clicking
1773  the root restores the default view.  To expand/collapse a branch, click
1774  on the "[+]" or "[-]" icon to the left of the survey name.
1775
1776* aven: The measuring line can now measure to anywhere in plan or elevation
1777  view (not just to a station!)  In plan view the horizontal distance and
1778  bearing are shown, while in elevation view the vertical distance is shown.
[90d0d71]1779
[ac3f376]1780* aven: Moving the mouse over a station in the survey view now highlights
1781  that station in the survey tree (though it may not be visible if the
1782  survey(s) it is in aren't expanded).
1783
1784* aven: Clicking on a station to centre the view now moves the mouse pointer
1785  to the new location of the station (except on Mac OS X where this isn't
1786  allowed).
1787
1788* aven: Fix which presentation toolbar buttons are shown as depressed.
1789
1790* Fix infinite loop reading 3d files with LRUD data (bug introduced in 1.1.9).
1791
1792* vim files are now installed with the correct paths (bug introduced in 1.1.9).
1793
[920b066]1794Changes in 1.1.9 (2006-07-04):
[6a2594be]1795
1796* (Unix version): Install desktop files for aven and svxedit contributed to the
1797  Ubuntu package by Phil Bull, and corresponding pixmaps.
1798
1799* Fix img to filter out cross-sections which don't match the subsurvey (if
1800  specified).  The API now returns img_XSECT_END to mark the end of a
1801  passage rather than setting a flag on the last img_XSECT of the passage.
1802
1803* Enhance integration with the vim editor - this can now colour .err files, run
1804  cavern from vim and parse error output, and run aven from vim.  Tweak the
1805  existing vim mode for .svx files to fix a few minor bugs and add support for
1806  the new "*data passage" style.
1807
1808* aven: fix drawing of the "blob" end of the measuring line on graphics cards
1809  which can't draw large enough blobs for us.
1810
1811* aven: sort out confusion about what encoding everything is in which means
1812  that the distance measured by the measuring line actually gets displayed
1813  and also fixes problems with empty menu items in non-English locales in
1814  some cases.
1815
1816* aven: redraw grey background after a menu is closed over the aven window
1817  with no survey loaded.
1818
1819* aven: fix bug which caused printing to crash (introduced in 1.1.8).
1820
1821* aven: avoid crash on some machines when opening "About" dialog before having
1822  loaded a survey.
1823
1824* aven: Translate "Plan" and "Elevation" buttons in print view dialog.
1825
1826* (Unix version): aven: Fix character set handling of cavern output.
1827
1828* cavern: Report an error if a cross-section is specified for a station which
1829  doesn't exist.
1830
1831* Updated French and Italian translations.
1832
1833* (Unix version): aven: Fix "Can't open message file `en_US' using path
[f3cfd13]1834  `${prefix}/share/survex'" error.
1835
[6a2594be]1836* Fix bug in 3d file reading on 64 bit platforms when used in STANDALONE mode
1837  (doesn't affect Survex itself, but other applications which use img.c should
1838  update their copy).
1839
1840* (Unix version): Add checks that wxWidgets is a non-unicode version (wx 2.6
1841  and later are caught by configure, whereas older wx versions are caught when
1842  trying to compile).
1843
[920b066]1844Changes in 1.1.8 (2006.06.30):
[cd39f67]1845
[c988ae4]1846* Drop support for building with wxWidgets versions prior to 2.4.0
1847  (which was released on 2003-01-07).
1848
[9577fcc]1849* aven: Printing through aven now uses settings from the "[aven]" section
1850  of print.ini, and support for hierarchical sections (using "like=")
1851  has been disabled.
1852
[ecf2d23]1853* aven: Change mouse actions to be compatible with those in Survex 1.0.
1854  The mousewheel now zooms in/out (it doesn't do anything in 1.0) and
1855  left drag is now smart about not rotating and zooming at the same
1856  time.
1857
[d1628e8e]1858* aven: Highlighting stations now happens as you type, and pressing
1859  "Enter" or clicking the "Find" button now pans and zooms to show the
1860  highlighted stations.
1861
[e67ed1b]1862* aven: Left-clicking away from a station now cancels measuring line.
1863
[3ddd351]1864* aven: Setting view to North, South, East, or West is now animated like
1865  the tilt from plan to elevation.
1866
[c988ae4]1867* aven: Fix presentation saving to also write "." for decimal points and
1868  presentation loading to accept either "." or ",".
1869
1870* (Unix version): aven: Add text for all toolbar items so that aven
1871  will work with the Gnome desktop preference for displaying toolbars as
1872  icons with text or just text (wxWidgets needs fixing first though).
1873
1874* (Unix version): aven: Remove the ability to detach the menu bar (yell
1875  if you actually used it and I'll restore it!)
1876
1877* aven: Add "all survey files" option to the "open file" dialog.
1878
[84f1ed1]1879* (MS Windows version): aven: Fix cursor keys to pan survey.
1880
[a884696]1881* (MS Windows version): Built with wxWidgets 2.6.3 instead of 2.6.2.
1882
[9fe7af4f]1883* (MS Windows version): Fix installer to work on Windows 2000 or XP if
1884  run by an unprivileged user.
1885
1886* (MS Windows version): Upgrade to the latest version of InnoSetup (the
1887  installer builder we use) and include new installer translations for
1888  UK English, Spanish, Brazilian Portuguese, Italian, Romanian, and Slovak.
1889
1890* (MS Windows version): aven: Include Catalan and Brazilian Portuguese
1891  translations of messages for wxWidgets (the GUI library we use).
1892
[cd39f67]1893* aven: Disable "Highlight exported points" if there aren't any.
1894
[afffec4]1895* Updates to French translation from Michel Bovey.  Also updates to German,
[5e74c26]1896  Italian, Catalan, Spanish, and Romanian translations.
[581624b]1897
[38a192d]1898* (Unix version): test suite: fix smoke test to pass even without X running
1899  (it was meant to but the code had a bug).
1900
[5892e08]1901* aven: Check if OpenGL is available and exit cleanly with a helpful error
1902  if it isn't.
1903
[879e9c3]1904* (Unix version): aven: Fix --help and --version to work without a working
1905  X display (provided it's built with wxWidgets 2.5.1 or newer).
1906
[c8f929b]1907* aven: Automatically select the presentation tab of the notebook when the user
1908  selects "New Presentation" or "Open Presentation".
1909
1910* aven: Fix "Delete" in the presentation list to not get passed on (and so not
1911  reset to default view as well).
1912
1913* aven: Fix Ctrl+Insert in the presentation list not to segfault if the list is
1914  empty.
1915
1916* aven: Fix Cursor Up and Down in the presentation list to move the highlight
1917  up and down instead of being passed on and moving the survey.
1918
[9ad92cc]1919* aven: Improve SVG output compatibility.  Tested with Mozilla Firefox 1.5,
[ecf2d23]1920  Adobe's SVG browser plugin, Gimp 2.2.8, Gqview 2.0.0, Opera 8.5,
1921  Safari 2.0.3, and InkScape 0.42.
[9ad92cc]1922
1923* aven: Put a 5mm border around exported SVG files to allow for station markers
1924  and non-zero width lines.
1925
1926* aven: Fix crash when exporting as SVG or Sketch if labels or surface data
1927  was turned on.
1928
1929* aven: Actually close the file we're exporting which fixes problems with it
1930  not always being fully written.
1931
[920b066]1932Changes in 1.1.7 (2005.10.18):
[6662d02]1933
1934* cavern: Add validity checking for dates in *date commands (with feature
1935  test in testsuite).  A date entered as just "year" or "year.month" now
1936  becomes a date range for the relevant period (previously it became a single
1937  date near the middle of that period).
[e0c7cd1]1938
[8add4c9]1939* extend: Fixed 2 uninitialised flags (should fix erratic behaviour on
1940  with MS Windows).
1941
[9f524ee]1942* extend: Default output name for a file called input.3d is now input_extend.3d
1943  rather than just extend.3d (which was annoying if you wanted to extend
1944  several surveys in the same directory).
1945
[185d793]1946* aven: OpenGL 2.0 always includes support for point sprites so rework
[3efd6b6]1947  our check for them to include that knowledge.
[185d793]1948
[3515947]1949* aven: Regenerate depth bar if user switches to/from metric units.
1950
[1235f9b]1951* aven: Don't clear the "there" mark just because the mouse pointer has
1952  moved off a station.
1953
[4299674]1954* aven: When processing a .svx file, put the resultant .3d file in the
[d74279d]1955  same directory (since that's where we then try to load it from).
[4299674]1956
[60dbe70]1957* aven: Fix labelling of date colouring on 32 bit platforms.
1958
[125c9ea]1959* aven: If "colour by date" is on and we load a survey with no date info
1960  (or all surveyed on the same date) then set "colour by none".
1961
[ec58e3d3]1962* aven: Make the error dialog modal and remove a signal handler once it
1963  has fired to prevent endless (or seemingly endless) cascades of error
1964  dialogs.
1965
[8add4c9]1966* aven: Enforce a minimum object volume diameter of 1m to avoid problems
1967  if a survey file with only one station in is loaded.
1968
[6662d02]1969* aven: Fix problems with indicators disappearing when we're drawing
1970  blobs and/or crosses the slow (but always supported) way.  (Problem
[d74279d]1971  introduced in 1.1.6).
[6662d02]1972
[b65c13f]1973* (Unix version): aven: Really stop setting extra toolbar margin when using
1974  GTK2.0.  The attempt to fix this in 1.1.3 failed because __WXGTK12__ is
1975  set for GTK+ 1.2 or *any later release* so is true for GTK+ 2.0 too!
1976
[17cce5f]1977* (Unix version): aven: Add details of which of wxGTK, wxMotif, and wxX11
1978  we've been compiled with, and which GTK+/Motif version where appropriate.
1979
[affaeee]1980* (Unix version): Fixed build on Fedora Core 3.
1981
[618b01f]1982* documentation: Updates to 3d file format specification from Mike McCombe.
1983
[920b066]1984Changes in 1.1.6 (2005.10.10):
[7e01c87]1985
1986* (MS Windows version): Distribution is about a third smaller than 1.1.5
1987  (mostly because mingwm10.dll is no longer required).
1988
[b88b171]1989* aven: If aven is asked to load a .svx, .dat, or .mak file, run cavern on
1990  it, showing cavern's output in a window (with errors and warnings clickable
1991  to load the offending file into an editor), and then loading the resulting
1992  3d file.
1993
[7e01c87]1994* aven: Added "Colour by Date" option.
1995
1996* aven: Disable "Colour by Depth" option if there's no elevation variation.
1997
1998* aven: Don't crash if trying to load a survey with no elevation variation.
1999  Instead turn off depth colouring.
2000
[8ea82aa]2001* aven: Export as HPGL added.
2002
[887c26e]2003* aven: Improved update of mouse coordinates and measuring line (thanks to
2004  Martin Green).
2005
[7c29c976]2006* aven: Show the coordinates of either the mouse pointer or the nearest
2007  survey station to it (if there is one near enough).  Showing both was
2008  confusing and meant the status bar overflowed on smaller displays.
2009
[7e01c87]2010* aven: When printing an extended elevation, don't show bearing and elevation.
[bd21214]2011
[7e01c87]2012* aven: Don't lock "flat" surveys which aren't extended elevations - a
2013  flat survey with LRUD data isn't flat any more!
2014
2015* aven: When we have to draw blobs and crosses the slow way (because the
2016  graphics hardware doesn't support the fast way), draw them so that they
2017  should appear at the correct depth into the 3D scene instead of on top
2018  of everything else.
2019
2020* aven: Make "play presentation backwards" icon green to match the other
2021  presentation icons.
2022
2023* (MS Windows version): aven: Mouse clicks on the survey view now set the
2024  keyboard focus there.
[bd21214]2025
[b46bf92]2026* (MS Windows version): aven: Fix first redraw of a newly loaded survey.
2027
[796d7bf]2028* (MS Windows version): aven: Fix redrawing of measuring line.
2029
[7e01c87]2030* cavern: Store dates for img_XSECT.
2031
2032* cavern: Fixed small one-off memory leak if you specify -o more than once.
2033
[b88b171]2034* (Unix version): Check environmental variable LC_MESSAGES when deciding what
2035  language to use for messages.
2036
[7c29c976]2037* (MS Windows version): "Print" on a 3d file now prints through aven rather
2038  than the separate printer driver (Unix has done this for some time).
2039
[8ea82aa]2040* Removed old printer drivers.
2041
[7e01c87]2042* img library: When creating a 3d file, ignore img_XSECT if we've been asked
2043  to write a file format version which doesn't support it.
[8ea82aa]2044
[920b066]2045Changes in 1.1.5 (2005.09.20):
[106cfdf]2046
2047* (MS Windows version): aven: Fixed crash on start-up (introduced in 1.1.4).
2048
[4ba80e0]2049* aven: Make blobs round like they are in Survex 1.0.
2050
2051* aven: If the graphics drivers don't support drawing blobs using OpenGL
2052  point markers, fall back to drawing filled circles.
2053
[95ce35f]2054* aven: If the graphics drivers support it, draw crosses as texture mapped
2055  OpenGL point markers which is much faster.
[90d0d71]2056
[95ce35f]2057* aven: Cross size increased to match Survex 1.0.
2058
[cd78148]2059* aven: We must update which blobs are displayed if display of surface or
2060  underground legs is toggled.
2061
[f5627353]2062* cavern: Fix handling of a *solve followed by survey data, none of which is
2063  attached to the previous data.
2064
[dfe4a520]2065* cavern: Fixed "No survey data" error when a *solve is followed by another
2066  *solve (or the implicit solve at the end of processing) with no data between
2067  them.
2068
[920b066]2069Changes in 1.1.4 (2005.09.19):
[4855072]2070
2071* aven: Added Aven's icon to the "About" dialog.
2072
2073* aven: Use localised character for the decimal point (e.g. "," in most
2074  continental European countries).
2075
2076* aven: Previously the survey tree would get focus and then take keypresses
2077  (e.g. "P", "L", "Delete").  Now we pass most keypresses across so they
2078  operate on the cave, and transfer the input focus across when we do.
2079
2080* aven: Make pressing "Return" in the tree control expand/collapse a subtree.
2081
2082* aven: Speed up intialisation by delaying creation of OpenGL lists until
2083  they're needed.
2084
2085* aven: Added Mark Shinwell's bounding box with shadow of the survey.
2086
2087* aven: Disable the "Tubes" button/menu item when there's no LRUD data.
2088
2089* aven: Reworded "Restore Default Settings" as "Restore Default View".
2090
2091* (Unix version): aven: Set sensible default margins for printing and preserve
2092  any margin values the user specifies between runs (previously margins
2093  defaulted to 0 each time aven was run).
2094
2095* Documentation: Document *DATA PASSAGE in the manual.
2096
[920b066]2097Changes in 1.1.3 (2005.09.07):
[0e558e5]2098
2099* (Microsoft Windows version): Fixed build problems.
2100
2101* cavern: Allow OMIT character (-) for left/right/up/down.
2102
2103* aven: Remove an unnecessary menu separator.
2104
2105* aven: Fix "Find" and "Hide" toolbar buttons to work with GTK2.0.
2106
2107* aven: Make the tooltip for "Hide" show the number of found stations.
2108
2109* aven: If * or ? is used in a glob-style pattern, force a non-substring match.
2110
2111* aven: Enable "New Presentation" when there's a 3d file loaded, rather than
2112  when there's a presentation loaded.
2113
2114* aven: Make entrances green in side panel tree list to match green blobs used
2115  in cave view.
2116
2117* aven: Don't show surface labels if we're not showing surface data, etc.
2118
2119* aven: Merge "Start Rotation" and "Stop Rotation" into "Toggle Rotation" and
2120  make "Space" the key for this.  Keep Return working "Stop Rotation" so
2121  existing users are happy, but don't advertise it.
2122
2123* aven: Normalise filename by adding any extension used, and use the normalised
2124  filename for file history and window title.
2125
2126* (Unix version): aven: Stop setting extra toolbar margin when using GTK2.0
2127  as the toolbar buttons already have a sensible margin - the extra margin is
2128  only needed with GTK1.2.
2129
2130* aven: Fix handling of plumb legs in tube model.
2131
2132* aven: Fixed swapped L and R in tube model.
2133
2134* extend: Preserve UD cross-section information in extended elevation.
2135
2136* extend: Add new messages for John Pybus' enhancements.
2137
2138Changes in 1.1.2 (never formally released):
[8faa5d8]2139
2140* Added support for LRUD data in .svx files, in .3d files, and aven can
2141  now load and display it on screen and on printouts.  The ability to "fake"
2142  LRUD data in aven is gone for now but will reappear in some form later.
2143
2144* cavern: Removed support for writing Chasm's 3dx format.  We're going to
2145  fold any desirable missing chasm functionality into aven.
2146
2147* aven: Rearranged mouse actions as discussed on the mailing list.  Added
2148  cursors for each different mouse action to help the user learn what each
2149  does.  Also added cursors for the "compass" and "clino" as well as the
2150  scalebar to suggest to the user that they can be dragged to change the view.
[1a09e2c]2151
[0e558e5]2152* (Unix version): aven: Don't segfault if LANG isn't a known language.
[8faa5d8]2153
2154* tests/smoketest.tst: If X windows is running, check that we can run aven
2155  with --help and --version.
2156
2157* tests/cavern.tst: Fixed cavern.tst to warn if it is skipping a test because
2158  no results are listed for it.  This revealed that there was a "newline" test
[6225339]2159  which should have been called "badnewline", and was a broken testcase too!
[8faa5d8]2160  Fixed all these problems.
2161
2162* cavern: Applied Simeon Warner's patch for handling backcompass, backclino,
2163  and omitted forward compass/clino readings in Compass DAT files.  Added
2164  a feature test for this to the testsuite.
2165
2166* It no longer makes sense to have an option not to build aven or to build aven
[0e558e5]2167  without OpenGL so remove old machinery for this from configure and the
2168  sources.
[8faa5d8]2169
[0e558e5]2170* (Unix version): configure: Check if "-lXxf86vm" is needed.
[8faa5d8]2171
2172* configure: Better output for strcasecmp test.
2173
2174* aven: Fix crosses to work much better.  Not a total fix - their position
2175  in the Z buffer isn't correct and they're rather slow to plot.
2176
2177* aven: Don't regenerate the hittest grid every time the mouse moves while
2178  animating, which solves the mysterious pausing effect (thanks go to Martin
2179  Green for spotting this!)  Also clear all the status bar coordinates when
2180  animating.
2181
2182* aven: Sort out clashing menu shortcuts in some languages.
2183
2184* aven: Fixed compilation problem on x86_64
2185
2186* SPUD: Pruned out stuff which has been done or which is not actually relevant
2187  to this branch.
2188
2189* Merge various changes from 1.0 branch:
2190
2191  + aven: Port over "printing from aven" functionality.
2192
2193  + aven: Port over "export as" functionality,
2194
2195  + Add David Loeffler's vim mode for .svx files.
2196
2197* aven: Fix check for whether a label is behind us in perspective view.
[1a09e2c]2198
[8faa5d8]2199* aven: Don't use an opengl list for drawing the indicators - we typically make
2200  a new list each time we plot them anyway.
2201
2202* Remove lingering traces of support for RISC OS and pre-386 MSDOS
2203
2204* aven: Set icon on non-Windows platforms too.  This means that with
[0e558e5]2205  WindowMaker on Unix you get an icon on the AppIcon by default.
[8faa5d8]2206
2207* configure: Update wxWindows checks to handle newer wx versions.
2208
2209* Make all maintainer perl scripts "use bytes;" to avoid utf-8 double encoding
2210  problems.  They also all require Perl 5.8 now (hopefully this isn't an issue
2211  for anyone building from CVS).
2212
2213* acinclude.m4: Quote macro name for fix autotools warning.
2214
[4855072]2215* Documentation: "tilt up" is "'" not ",".
[8faa5d8]2216
2217* aven: Add support for mousewheels (to tilt the cave).
2218
2219* aven: Fixed twisted transitions to and from pitches in certain cases.
2220
[0e558e5]2221* aven: Pick a sensible initial window size when the user's desktop is spread
2222  over more than one monitor (works best with wx2.5 or newer, but try to do
[8faa5d8]2223  better with wx2.4 or earlier as well).
2224
2225* aven: Initialise GfxCore slightly later to avoid visual glitch from notebook
2226  contents being visible before any survey is loaded.
2227
2228* aven: Allow a coloured texture to be used
2229
2230* aven: Don't initialise until we have data (to the user, this means the window
[0130bc4]2231  is default colour (grey for most systems) not black until a survey is
2232  loaded).
[8faa5d8]2233
2234* aven: Fixed weird "shadowed" icons.
2235
[920b066]2236Changes in 1.1.1 (2004-10-06):
[a7aa27d9]2237
2238* (Microsoft Windows version): aven: Hopefully fix loading a survey file at
[1a09e2c]2239  startup.
[a7aa27d9]2240
2241* aven: Delay loading the bitmap for the "About" dialog until it is first
2242  needed.  We want start up to be as quick as possible.
2243
[920b066]2244Changes between 1.0.32 and 1.1.0 (never formally released):
[edb6576]2245
[91e416e]2246* NOTE: Survex 1.1.X releases are development snapshots made available for
2247  the purposes of allowing wider testing and getting more user feedback.  Once
2248  the code has stabilised the version number will be raised to 1.2.0.
[edb6576]2249
[91e416e]2250* aven: Now uses OpenGL for 3d rendering - you may need to install drivers if
2251  you're using Windows 95 - these can be obtained from:
2252  http://download.microsoft.com/download/win95upg/info/1/W95/EN-US/Opengl95.exe
[edb6576]2253
[91e416e]2254* aven: Solid passages - passage dimensions are currently inferred from
2255  the leg length (pretty effective as you can measure longer legs in
2256  larger passages).  Use of real LRUD data coming soon...
[edb6576]2257
[91e416e]2258* aven: Depth colouring is now continuously varying.
[edb6576]2259
[0580c6a]2260* aven: Colour by depth can now be turned off (and there's the start of a
2261  framework for properly implementing colour by date, error, etc).
