aven: Fixed font sizes in "Print Preview" and printouts.
aven: In the print setup dialog, replaced "Orientation" radio buttons with "Plan" and "Elevation" buttons.
aven: Fixed info box on printouts of elevations, tilted views, and extend elevations.
aven: Added "fit on one page" option, and make it the default.
aven: Reorder "Cancel", "Preview", "Print" buttons and make "Print" the default button.
aven: Read settings back from the print dialog when the "Print" button is pressed (was only done for "Preview" previously).
aven: Sorted out the initial size of the "Print Preview" window.
aven: Fixed the window manager's close button on the "Print Preview" window - previously this was being ignored.
aven: Sorted out initial survey scaling when loading a survey at startup.
aven: Fixed the measuring line to work better when the survey tree is manipulated with keys. Tweaked redrawing of the measuring line to be a smidgen more efficient. Fixed the blob and ring size which were one pixel too small on Windows.
aven: Added "System Information:" section to the "About" dialog to hold information useful when reporting bugs. Currently it contains the wxWindows version, OS version, and colour depth information.
aven: Changed the "About" dialog's "Close" button to be "OK" for consistency with pretty much every other application.
aven: Added "File->Export as..." which integrates cad3d's functionality within aven.
aven: Updated a few icons.
cad3d: Added SVG export support from John Pybus
(Unix version): Fixed to allow compilation with GCC 3.4
(MS Windows version): Upgrade to using innosetup 4 for the installer (we were using innosetup 2). This results in a much smaller download and the installer now translates itself into the currently set language. The installer will no longer work on Windows NT 3.51, but I seriously doubt anyone is still using that...
Updates to German translation.
(MS Windows version): Fixed problems with the new printing code by building with a newer version of wxWindows (2.5.2 instead of 2.4.1).
aven: Fixed grid menu item so that it always correctly reflects whether the grid is enabled or not.
aven: Minor improvements to appearance of a few toolbar icons.
Updates to Catalan, French, Italian, Romanian, Slovak, and Spanish translations.
cavern: Fixed Romanian message which was appearing in English .err files.
aven: Added printing directly from Aven!
aven: Fixed memory leak when showing the "About" dialog.
(MacOS X version): Now installable from a disk image package.
cavern: Equates are no longer considered when deciding which stations are flagged as surface and underground.
Romanian translation mostly completed.
(Unix version): Debian: Minor packaging tweaks.
cad3d: Fixed problem with DXF files which stopped them loading with some drawing packages (introduced in 1.0.27).
aven: Changed File->Exit to File->Quit.
Removed some unused messages from the message files.
(Unix version): Fixed SRPMs to build on RedHat 9 and Fedora Core 1 (patch from John Pybus).
Romanian translation started.
(Unix version): Debian: Fixed new lintian warnings about missing quotes in menu files.
Fixed 3d file reading code to fix incorrect unpacking of compressed station names in a rare case. Also checked other rare cases work correctly.
cad3d: DXF output now puts surface legs, stations, and labels in separate layers.
(Unix version): distribute desc-svxedit.txt.
cavern: Fixed interleaved topofil data style - the length was always being calculated as zero.
(Unix version): aven: "All Files" now shows files without extensions too.
aven: added Ctrl+Q as shortcut for File->Exit.
aven: depth colouring now uses a proper colour gradient.
(MacOS X version): aven: the keyboard and mouse now work! It turns out that we must apply resources *after* installing.
(MacOS X version): aven: now works when run from the MacOS X Finder.
(MacOS X version): look for message files and other resources relative to the binaries so that the user can install Survex from a disk image in the location of their choice.
(MacOS X version): fixed not to try to build aven if wxWindows isn't installed.
cad3d: fixed -e and -r options to not crash (the long versions have always worked).
extend: fixed to initialise an internal structure - failing to do so was probably causing crashes on some platforms.
Fixed standard graphics for "Note", "Warning", etc in the PostScript manual.
Documentation updated.
(Unix version): fixed svxedit man page which previously contained xcaverot documentation!
test suite: check that cavern doesn't report "nan" or "NaN" for any values.
(Unix version): fixed configure --enable-defaultlang=XX to work.
(Unix version): fixed configure code to turn on lots of GCC warnings and fixed most of them.
(MS Windows version): assorted tweaks to allow building with MS Visual C/C++.
(MacOS X version): hopefully fixed building of aven.
(Unix version): updated config.guess and config.sub so should build out of the box on more Unix platforms.
(Unix version): Debian: added missing Build-Depends on xlibs-dev.
(Unix version): RPMs: give up supplying binary RPMs due to apparently insurmountable technical problems.
cavern: fixed LEVEL (broken since around 1.0.8) and added test case.
cavern: corrected handling of declination in Compass DAT files and added test case; also added tests for other aspects of Compass DAT file reading.
printps/printpcl: fixed blank page detection in some obscure cases.
Documentation: started manual section on working with Compass data files.
(Unix version): fixed compilation problems with aven and getopt.h on MacOS X (and probably some other Unix versions).
(Unix version): Debian package now Build-Depends on gcc-3.2 and g++-3.2.
Documentation: include 3d v3 file format description on MS Windows, MS DOS, and RISC OS too; include PNG graphics for manual on MS Windows; minor updates to manual.
Prefer wxWindows 2.4 if it's available.
(MacOS X version): detect MacOS X and look for MacOS X build of wxWindows; automatically add resource fork to aven binary.
Disabled experimental support for Chinese (LANG=zh) - it isn't currently working and makes the printer drivers unusable on Chinese versions of MS Windows.
(Unix version): tweaked debian packaging.
cavern: Handling of "*:" at start of file wasn't fully fixed in 1.0.19.
aven: Fixed handling of extended elevations (and other flat surveys) - they are meant to be "locked flat" but this wasn't fully working before.
Documentation: 3d v3 file format description: fixed error in description of codes 0x01-0x0e; include it in binary packages (not only with the source code).
cavern: when reading Compass DAT files, we now processes compass and clino backsights, and recognise the "X" flag which indicates a leg should be entirely ignored. And we now report correct line number with errors in Compass .MAK files.
cavern: if "*infer plumbs on", don't infer a plumb if the clino is +/- 90 degrees, but the backclino isn't (and vice versa).
cavern: fixed 3dx output so it actually works with Chasm once more.
cavern: don't allocate extra space needed for producing 3dx output for Chasm unless we're actually producing that output - saves about 8 bytes per station.
cavern: removed slightly too keen sanity check which could misfire in very unusual circumstances.
(MS Windows version): all .ico files except 3d.ico have been missing since 1.0.17 (or maybe 1.0.16) - fixed. You wouldn't notice this if you installed over an previous version.
aven: update display when "Metric" or "Degrees" is toggled.
cavern: fixed handling of compass and clino corrections in Compass survey data - these were interpreted as radians rather than degrees so the correction was about 57 times too large!)
Improved handling of Compass PLT files - if the survey name is empty, don't insert a survey separator character.
Documentation: fixed incorrect markup which resulted in a bogus footnote.
cavern: you can now process Compass format survey data (.DAT and .MAK files) - these can even be linked into a Survex dataset with "*include fulford.dat" or "*include lech.mak" to allow processing of mixed datasets.
cavern: major speedup (up to 60%) when reading in survey data containing a lot of stations in the same survey hierarchy level (which is how Compass files are handled).
cavern: don't warn about a compass reading on a plumbed leg if the plumb was inferred and the compass reading is zero.
cavern: reduced memory usage in code which reads a survey station name.
cavern: reported CPU time would go negative if cavern ran for more than about 36 minutes (highly unlikely but not impossible on a slow machine with a large, highly interconnect survey) - fixed.
cavern: avoid unnecessary work when --percentage isn't specified.
cavern: Writing "*:" at the start of a .svx file would crash cavern - fixed and added test case. This is an error anyway, but it shouldn't cause a crash.
Don't distribute unused toolbar icons.
Documentation: minor updates.
(Unix version): Fixed "Process" action on .svx files.
(Unix version): File associations: if svxedit isn't installed, run gnome-edit instead.
(Unix version): In Debian packages, now include file associations and file icons in the survex package rather than survex-aven.
(Unix version): File associations were missing from RPM packages; moved aven and svxedit man pages to their respective subpackages; moved aven icons to the aven subpackage.
Documentation: added details of the 3d file format (version 3).
Updated TODO list.
(MS Windows version): Fixed "Open in SvxEdit" to work (and if tcl isn't install this action now falls back to using notepad). SvxEdit now has its own icon.
(Unix version): Install mime types, icons, and file associations for Gnome. Note: at present GMC doesn't seem to notice new files being created (e.g. Process on a .svx file creates .3d and .err files) - you have to manually refresh the view.
Minor update to manual.
(MS Windows version): Really fixed bug introduced in 1.0.14 which often stops programs from finding the message files.
(MS Windows version): Remove any existing "Open" file association for .svx files.
(MS Windows version): Fixed bug introduced in 1.0.14 which often stops programs from finding the message files.
(MS Windows version): "Open in Notepad" is now the double-click action for .svx files once again, "Open in SvxEdit" is an action in the menu obtained with the right mouse button.
svxedit: This is a Survex data entry editor from the therion team. It needs tcl and wish installed - for MS Windows an installer is available for free from Activeware.
Improved handling of Compass PLT files and CMAP xyz files - no longer change dots to spaces in survey and station names - instead use a space as the separator between survey name and station name.
aven: when picking non-overlapping labels, show a slight preference to shorter labels with the aim of displaying more labels.
aven: fixed hard to notice problem which could cause the cave to appear tilted sideways after a lot of manipulation.
cavern: Modest speed improvement (0.5% for sample dataset).
cavern: fixed a rarely sighted bug which caused erroneous error about some stations not being attached to a fixed point.
cavern: fixed clino readings and DIRECTION to work in interleaved data.
cavern: improved error reporting when an invalid value is given for a DIRECTION reading.
cavern: fixed "singular matrix" error when very low SDs were specified.
print*: if the --raw is used, the survey can now use the space this would have taken up.
Reading of ASCII 3d files now copes with MSDOS/MS Windows line endings once again. Added regression test for this.
(MS Windows version): Programs run from the command line now find message files without SURVEXHOME needing to be set.
Updated documentation.
aven: Fixed bug which caused the occasional spurious leg to be shown connecting arbitrary stations.
extend: try to extend along a survey, and make breaks where other surveys join.
cavern: Number reading code reworked to allow repeat readings to be supported, but the actual repeat reading code is currently disabled, and everything should work exactly as before.
Experimental support for Chinese (LANG=zh) - only a few messages are currently translated.
diffpos: fixed to work on 64bit architectures.
sorterr: fixed to work with more than 1024 traverses.
Fixed handling of iso-8859-2 character set and MS Windows code page 1250 (both cover Eastern European languages).
(MS Windows version): install file associations for Compass .plt and .plf files and for CMAP .xyz files. Also install the file icon for .plt and .plf files in case Compass isn't installed (thanks to Larry Fish for permission to include the icon).
(Unix version): running an installed program with an explicit path works again.
(Unix version): xcaverot: automatically switch on PDA mode if the screen is less than 640 pixels wide or less than 480 pixels high.
(Unix version): minor portability improvements.
Updates to Portuguese translation - all translations are now up-to-date.
aven: improvements in 1.0.10 to the file type selector only work properly on MS Windows, and with wxGtk >= 2.3 on Unix (the latest stable release is 2.2.9 where this doesn't work). Fixed to work as well as possible on 2.2.9, and as intended on 2.3.
aven: fixed so that loading PLT files works regardless of the current locale (previously it would fail for locales where the decimal character wasn't '.').
aven: key actions during autorotation no longer temporarily pause autorotation.
aven: switching to plan or elevation while rotating is now smooth.
aven: removed undocumented and confusing "free rotation mode".
(MS Windows version): aven: focus now set correctly after loading a file by double-clicking or from the command line.
cad3d: write dummy passage dimensions to .plt files to avoid Compass bug.
printwin/printps: now support coloured printouts.
print*: fixed to work correctly with PLT files.
extend: fixed to work correctly with PLT files.
Updates to Italian translation.
Minor documentation updates.
(MS Windows version): aven: fixed assert failure upon turning on station names.
aven: only add a file to the list of recently used files if it was opened successfully.
aven: recognise ".plf" as a Compass PLT file too; and on Unix list "*.PLT", "*.PLF", "*.XYZ", and "*.3D" as well as the lowercase versions to help people who transfer files from MSDOS/MS Windows.
cavern: fixed bogus warning triggered by "*begin abc.def" (I'm not sure that this should be valid, but the warning given wasn't appropriate).
Fixed scaling problem when reading PLT file (feet->metres conversion factor was being applied backwards!)
Fixed potential problem when reading or writing a 3d file which couldn't be opened.
Translate dots to spaces in survey names in Compass PLT files.
Better handling of PLT files which have a D command before any M command.
Updates to German and Italian translations.
aven: Fixed jerky start when auto-rotation begins.
cavern: Fixed Direction reading - bug previously made it unusable.
(MS Windows version): cad3d: fixed broken PLT output (had a double CR at the end of each line).
(Unix version): RPMs now have the docs in /usr/share/doc and the man pages in /usr/share/man to conform with the FHS (and where RedHat packages put them).
Updates to French, Spanish, Catalan, and Slovak translations.
Slovak translation added; updated German, Catalan, and Spanish translations.
aven: reduced memory usage by around 25% and increased speed and responsiveness.
aven: rate of rotation and switching between plan and elevation now adjusted to the speed of redraw, so aven behaves in a similar way independent of the speed of the computer or size of the survey.
aven: provide list of most recently loaded files (preserved between runs of the program).
aven: settings for "Metric" and "Degrees" are preserved between runs.
aven: moved some menu items from "View" to "Controls" as they probably belong there and the "View" menu was getting out of hand.
aven: cursor keys now translate cave in the same way the mouse does (i.e. now work as in caverot and xcaverot).
aven: eliminated the "twinkling label" effect when dragging the cave with the right mouse button.
aven: the measuring line moves much more smoothly now: the mouse cursor now snaps to the nearest station, rather than just a near station; and when the line moves, we now only redraw the affected area of the window.
aven: resolved annoying limit on zooming in on large surveys. This was a crude way of preventing random lines due to overflow in the windowing system. Aven now clips lines itself at high zoom levels, and limits zoom in to approximately 1mm/pixel.
aven: zoom in/out with keyboard wasn't subject to any limits - now restricted to sane values as with zoom in/out with the mouse.
print*: added --raw switch to turn of info box, scale bar, and page footer. This can be useful if you want to import the output into another application.
print*: improved output when --no-border is used.
printpcl/printdm: Added new .ini setting "font_bitmap" which allows the user to choose between alternative fonts. Current we supply "default" and "bold".
printps/printhpgl: Fixed --skip-blanks which would incorrectly skip non-blank pages on rare occasions.
cavern: added support for BackCompass and BackClino.
cavern: implemented "*units clino percent".
cavern: added "*infer exports on". Any stations seen while this is on will have the necessary *export-s inferred when accessed from outside their own survey. This allows linking a survey which uses *export to one which doesn't. It's also useful for a maze cave where so many stations can be linked to that listing them explicitly isn't desirable.
cavern: N-S, E-W, and vertical ranges now only count stations which are in underground surveys.
cavern: *infer plumbs wasn't inferring -90 to be DOWN - fixed.
cavern: *infer was giving an internal error if the argument was unknown - now it gives the correct error message.
cavern: fixed handling of omitted clino readings when OMIT is *set to be different from MINUS and PLUS (new test omitclino).
cavern: fixed a bogus warning for any station which was only used in a line of data which was rejected because of an error.
cavern: added error if the *units factor is zero (e.g. "*units tape 0 feet").
cavern: removed the ill-thought-out and never implemented LENGTHOUTPUT and ANGLEOUTPUT quantities.
cavern: resolved mismatch between bcra5.svx and the default SDs, and the odd values in bcra3.svx. We are now interpreting the BCRA limits as 2 standard deviations (previously bcra5.svx used 3 sds, bcra3 used 3.33 sds for tape and position, and .75 sds for compass and clino, and cavern used 1 sd by default).
ChangeLog now only includes entries since the previous release (the full file is 220K or so, and of interest to very few people). MSDOS and MS Windows versions now comfortably fit on a 1.44M floppy once again.
Test suite now checks that all programs will run successfully with "--help" and with "--version". This should avoid problems such as that which broke the printer drivers in 1.0.4-1.0.6.
(Unix version): uninstalled binaries now use the path they are run with to find support files, which means SURVEXHOME is no longer required, and has been removed.
print*: halted with a failed assertion in 1.0.4-1.0.6.
aven: "Reverse Controls" now works as in xcaverot and caverot.
aven: free rotation mode (engage by pressing control while left dragging, exit with Delete) improved.
aven: using File->Open when a file was already loaded caused a crash if a station was "grey highlighted" in the survey tree - fixed.
aven: added hourglass for "find" operation.
aven: reenabled loading of files by drag-and-drop (accidentally disabled in 1.0.4 and 1.0.5).
aven: improved handling of flat surveys (e.g. output of extend, surveys with no clino information).
aven: surveys with stations but no legs no longer cause the labels and crosses buttons to behave oddly.
aven: removed quite a bit of unused and superfluous code.
Spell-checked documentation.
Fixed bug in img_open_survey() which could cause a crash if you tried to open an unrecognised file (i.e. not .3d, .pos, .plt, or .xyz format).
North and East were the wrong way round when reading in .plt files.
cad3d: Improved .plt file output a little - there's probably enough file structure for Compass to read them now.
Documentation updates.
extend: previously only kept one name for an equated group of stations in the extended .3d file; now keeps all the names.
cad3d: if an output filename is given, use its extension to pick the default output format.
aven: movement with keyboard is now accelerated by Shift as in caverot.
print*: --no-borders fixed to work as documented; --no-cutlines added to turn off the dashed lines where pages join on multi-page printouts.
aven: tracked down two uninitialised variables which seems to fix the failure to load a survey on startup which some people have been experiencing on Microsoft Windows.
aven: code cleaned up - should improve performance a little.
img routines: img_rewind() now returns a value indicating success/failure.
Improvements to .plt file reading, notably that distances in the file are now interpreted as being in feet rather than metres. Also .plt files should now be recognised even with a different extension, and we cope with an odd special case better.
Added support for reading CMAP XYZ files. There are two variants of these - the "shot" format is fully implemented, the "station" format currently just reads the station names and positions - the legs are ignored (sadly the sample files I have do not match the format specification).
(MacOS X version): aven: aven now builds on MacOS X - we just need to sort out packaging now...
(MSDOS version): upgraded graphics library used to Allegro 4.0.1.
Documentation updates.
aven: you can now select distances to be displayed in feet (or miles when you zoom right out) instead of metres, and angles to be in grads instead of degrees.
aven: show altitude of mouse pointer when in elevation view.
cad3d: fixed bug which caused --plt to crash on some platforms.
print*: added "Printing to `XXX'..." message to say where output is being written.
Updated French translation; minor updates to other translations (mostly sorting out clashing menu shortcuts in aven).
(Unix version): assorted portability tweaks.
printdm/printpcl/printwin: take notice of font_size_labels setting in print.ini etc.
cavern: Topofil can now be used with DIVING and CYLPOLAR styles; TOPOFIL style is now synonymous with NORMAL.
cavern: *INFER EQUATES and *DATA TOPOFIL now work together correctly.
cavern: *FIX with 3 standard deviations but no covariances now works.
(MacOS X version): command line programs now build. We're working on Aven.
Updates to the Catalan and Spanish translations.
xcaverot: documented environmental variables XCAVEROT_INDICATOR_RADIUS and XCAVEROT_FONTNAME.
cad3d: added --plt option to produce crude approximation to Compass .plt files - should be good enough for reading into Carto.
img library enhanced to allow Compass .plt files to be read as if they were .3d files.
(MS Windows version): printwin: fixed sizes of cross and page alignment ticks.
Updates to the Portuguese and Italian translations.
Fixed --survey option supported by many programs which was broken in 0.99.
aven: altered colours of "fixed points" and "entrances" buttons to match the coloured blobs used to indicate them.
(MS Windows version): aven: changed current point highlighting in the survey tree to use a light grey background rather than bold (bold causes the text to "wriggle" as the highlight runs up or down).
(MS Windows version): file icons now have transparent backgrounds.
survex: removed conversion wrapper - you should use "cavern file.svx" instead of "survex file.svx".
(Unix version): GCC 2.95 sometimes fails with an internal error when trying to compile gfxcore.cc - if it does, the Makefile will now try recompiling with a lower optimisation level.
(Unix version): when doing an "in directory" build from source, the HTML manual is now installed in its own subdirectory as when doing a non "in directory" build.
German translation now completely up-to-date.
Fixed bug in .3d file reading code which would incorrectly reconstruct the survey hierarchy in rare cases.
(MS Windows version): aven: fixed redraw problem for "N found".
(MS Windows version): minor tweaks to .err, .pos, and .svx file icons.
(Unix version): aven: Highlight of current station restores old background colour correctly rather than assuming it's white.
aven: Resolved a number of menu shortcut clashes.
(RISC OS version): fixed automatic detection of language.
cavern: improved error reporting from *data; better handling of some incorrect usages of *sd and *units.
Italian translation updated.
aven: Side Panel can now be dragged or toggled shut and then reopened again; double-clicking on the divider now maximises the survey window rather than the side panel.
aven: .3d files can now be loaded using "drag and drop" from MS Windows Explorer, and X filemanagers which support XDND (e.g. Konqueror).
aven: fixed problems with selection handling in survey tree.
aven: Escape cancels distance measuring line; suppress distance measuring line during auto-rotation and animated tilting.
aven: entrance blobs now green to distinguish them from stations matching search.
aven: problems with dragging scalebar fixed.
(MS Windows version): aven: Loading file on start-up now works!
(MS Windows version): aven: Delete now works in the search box.
(Unix version): aven: Highlight current station in tree with grey background (don't seem to be able to use bold like we do on MS Windows).
cavern: Fixed handling of interleaved nosurvey data.
cavern: Diving and cylpolar styles now take DEPTHCHANGE where they used to take DZ.
(MS Windows version): Installer now uses a different compression method (bzip2) which reduces the download size by about 5% (and should help keep the installer small enough to fit on a 1.44M floppy). Bzip2 is a little slower to uncompress, but not appreciably so on the machines I've checked it on.
(MS Windows version): Should now install without errors for a non-admin user on MS Windows NT/2000/XP.
(MS Windows version): Installer should now allow installation on NT 3.51.
Updated manual (notably added documentation for interleaved data styles).
German and Brazillian Portuguese translations updated.
aven: Ctrl + Arrow keys is now the preferred way to rotate and tilt (easier to remember than "C"/"V" and "'"/"/").
aven: survey pane now gets initial focus so you no longer have to click on it before key presses are recognised.
(MS Windows version): aven: fixed problems with some keys being impossible to enter in search box, or not being recognised in survey pane.
(MS Windows version): aven: wxWindows messages files were missing. We now include them for languages which Survex also supports.
(MSDOS version): caverot: Shift and/or Ctrl + Arrow keys now works.
aven: Close button in About box is now always right in the bottom right corner.
Display copyright symbol rather than (C) where the current character set allows it.
(MSDOS version): caverot: default to 320x200 when running under Microsoft Windows 2000 and XP as we already do on NT.
(MSDOS version): fixed problem when running on DOS outside MS Windows.
(MSDOS version): detect current codepage rather than assuming it's 850. We now support codepages 437 and 850 (the common ones) - for other codepages we fall back to using 7-bit ASCII.
(Unix version): aven: now compiles cleanly with GCC3.0.
(MS Windows version): aven was missing from 0.99-prerelease6 (if you installed over an old version you'd have kept the old aven).
caverot/xcaverot: Ctrl + Arrow keys is now the preferred way to rotate and tilt (easier to remember than "C"/"V" and "'"/"/").
xcaverot: Shift-ed movement keys now work faster as in caverot.
cavern: fixed *calibrate depth/todepth/fromdepth/dz and *units dz to work in data styles diving and cylpolar.
cavern: fixed handling of malformed *data commands.
Various documentation clarifications.
aven: fixed bogus lines caused by coordinate wrap-around; fixed problem in repeated zoom with [ or ]; tweaked layout and auto-sizing of left panel; station search now case insensitive; regexp search enabled; suppressed message box when wxWindows doesn't support the language Survex is set to use; fixed obscure crash in search highlighting; added "rubber band" between measured stations; Improved choice of menu short-cuts in translations.
(MS Windows version): don't include plain text versions of docs; fixed default action for 3d files to be "Open".
(MSDOS version): include text docs.
cavern: more intelligent and less verbose reporting of errors in nested included files (inspired by GCC 3.0).
cavern: improved reporting of syntax errors in survey data.
print*: improved reporting of invalid scales; interpret a single number less than one as the scale in the obvious way (so "0.001" means "1:1000").
print*: "--crosses" no longer prevents "--station-names" from working.
print*: if running interactively, prompt for what elements to plot when run so MS Windows users don't have to resort to the command line.
Improved documentation for print.ini; Other minor documentation updates.
(Unix version) configure auto-probe for wxWindows updated to cope with wxWindows version 2.2.8 (still works with older versions too).
Diving and cylpolar styles now accept dz (change in depth) rather than requiring absolute depths and taking the difference.
aven: improved initial sizing of window; "Toggle rotation" toolbar icon now works; handle files with only stations better; presentation code disabled for 1.0; releasing mouse over menubar now ends drag; don't highlight hidden stations; accelerator problems fixed; find now works.
(MS Windows version) aven: fixed crash on File/Open when a file was already loaded.
cavern: After *solve, reused points are no longer written to the .3d file a second time.
cavern: Warn that the undocumented extra "omit" allowed by *data is deprecated.
cavern: Give error if standard deviation argument to *sd isn't positive.
Consistent capitalisation of --help option descriptions.
Minor improvements to manual and Unix man pages.
printps/printhpgl/printwin: --skip-blanks fixed.
printhpgl: fixed paper size for A1 landscape (was actually A2 portrait!)
(MSDOS version): graphics in HTML manual were corrupted (by being packed as text).
(RISC OS version): graphics were missing from HTML manual.
(RISC OS version and 286 DOS version): fixed programs to report themselves as part of "Survex" rather than "@PRETTYPACKAGE@".
(MSDOS version): pick a default language for messages by looking at the currently set country.
(Unix version): Improved test for whether build needs librx - before it was used if it was present, even if it wasn't needed.
(Unix version): Assorted minor debian tweaks.
Documentation rearranged. Some sections which covered the same ground have been merged, and the documentation for each program is now available as a man page under Unix.
(Unix version): Fixed problem with incomplete versions being specified in debian package dependencies.
(Unix version): Fixed problems with not having librx on Linux (it's now built into libc).
aven: fixed bug which caused occasional crash during mouse movement; station identifying didn't work after a resize until the survey was moved.
Asking for messages in language en_GB now tries language en as it was meant to.
printps/printhpgl/printwin: fixed typo which made --skip-blanks get it wrong in some rare cases.
(Unix version): Added man pages for 3dtopos and sorterr.
(Unix version): More minor tweaks to debian packages.
Include images with HTML documentation; other minor documentation changes.
Major clean-up of Survex Manual; renamed from "svxdocs" to "manual".
Text documentation converted to HTML; BUGS and TODO merged, ZOMBIES removed.
Include HTML documentation overview page and manual in all versions (was only included in MS Windows before).
aven: added new functionality: toolbar, side panel with survey tree, find station, measure distance between two stations, click on station to centre.
aven: can now create presentations consisting of a set of views with movements between them. Useful for using aven as a "slide show" in a conference talk.
aven: handles loading file from command line better.
cavern: added error checks for "*flags" (with no arguments) and "*flags not".
cavern: you can now specify optional covariances to *FIX.
cavern: parser fixed to recover from errors as intended in a few situations where it was failing to.
cavern: implemented covariances for diving data.
cavern: added "cylpolar" data style - similar to diving, except the tape is measured horizontally rather than along the slope of the leg.
cavern: complain about *export-ing or *entrance-ing a station which is never used.
cavern: complain about *export after a *begin without an argument.
cavern: use *title only if at top of survey tree, else generate title from filename(s).
cavern: removed dummy *lrud command which was added for tunnel but isn't used by tunnel.
cavern: round coordinates to nearest cm when writing .3d file.
cavern: fixed reporting of node stats for stations fixed with error estimates.
cavern: no longer generate a .inf file - the .log file generated by the --log option makes the .inf file obsolete.
cavern: only apply special pathname handling to filenames in *include, not those on the command line.
cavern: *date now checks its argument. It expects an ISO format date (e.g. 2001.09.13) or range (e.g. 2001.09.12-2001.09.13). For cases where the exact date isn't know, the day and month can be omitted - e.g. 2001.09 and 2001 are also valid.
cavern: --new-format renamed to --chasm-format.
print*: If restricting to a subsurvey, use that survey name for the title of the printout.
print*: Detect .3d files produced by extend and handle them more appropriately (don't ask for view or bearing, and modify info box on printout).
print*: --skip-blanks now works on printwin/printpcl/printps; --skip-blanks now forces --no-border.
printps: thinner lines by default (0.1 points rather than 0.5).
printdm: added --calibrate option to print calibration page; if there's no calibration in the .ini file, refuse to print (apart from calibration pages) rather than printing to the wrong scale.
printwin: removed --output option - there is no output file.
extend: wasn't picking start station as documented - fixed and also enhanced to try to find an entrance with legs first.
survex: conversion wrapper doesn't use --output unless it is actually needed, and displays corresponding cavern command line, and (if appropriate) file.
cad3d: added --reduction option (from Leandro) which allows sketch output to be scaled down (default scale is 1:500); grid in sketch file is now visible by default; default output now goes in the current directory.
cad3d/3dtopos/sorterr: delete output file if there's an error writing to it.
3dtopos: minor improvements to sort order.
hto2svx, svx2hto: Removed HTO support - Survex appears to be the only released software to ever have provided support, and an exchange format that nobody else supports is useless.
xcaverot: report more detailed error when .3d file can't be loaded.
`program --version' now works even if message file can't be found.
(Unix version): Fixed attempt to load messages from "DEFAULTLANG.msg" if both SURVEXLANG and LANG were unset.
Much more rigorous checking for operating system errors when reading and writing files.
(RISC OS version): query Territory module to find currently selected language, and use that for messages.
(UNIX version): man pages now have "Survex <version number>" on them; fixed minor flaws in man pages.
Distinguish between a "bad" .3d file and one which has a newer revision of the format than we understand.
img library can now read .pos files as if they were .3d files with just stations in, so all programs which can read .3d files can also now read .pos files.
Expanded testsuite further.
French, Brazillian Portuguese, and German translations brought almost completely up-to-date.
(Unix version): Lots of little improvements to debian packages (mostly from Wookey).
(MS Windows version): New icons for .svx, .pos, and .err files. Tweaked .3d icon to work better in 256 colour modes.
Added tests for `*infer plumbs' and `*infer equates'.
printwin: fixed new bug introduced in 0.98-prerelease4 which caused an internal error.
printwin: exit cleanly if no printer drivers are installed.
aven: surface surveys weren't being drawn when viewing from above (bug introduced in recent version).
aven/caverot/xcaverot/print*/cadgen/extend/diffpos/3dtopos: --survey command line option once more trims specified prefix from station names like it did in xcaverot/caverot in 0.98-prerelease4.
sorterr: Added --replace option to sort the .err file and replace the original with the sorted version (for use by MS Windows file associations); cope with empty .err file.
cavern: Added --log option to send output to a .log file.
cavern: --quiet no longer suppresses node statistics.
extend: give up if the .3d file is truncated or corrupted part way through.
(MS Windows version): sorterr.exe and 3dtopos.exe were missing; improvements to documentation; assorted fixes and improvements to file associations.
print*: reduced memory usage.
Fixed dropping of first character of survey station names when reading old .3d files.
(MS Windows version): aven.exe wasn't rebuilt for 0.98-prerelease - fixed the dodgy script.
aven/print*/cadgen/extend/diffpos/3dtopos: Added --survey command line option to restrict the operation of the command to a sub-survey in the .3d file.
aven: initial scaling now ignores unused fixed points (unless there are no legs at all), and scales survey so it fits inside window.
aven: can now load a survey with no legs, only stations.
aven: --version now works, and --help produces more helpful output.
cavern: fixed bug with eating first character of line after interleaved data; corrected line numbers in some situations involving interleaved data.
cavern: fixed problem with points fixed with errors.
cavern: *title without quotes now stops at a comment; *title with no argument no longer allowed - use `*title ""' if you really mean to set an empty title.
Minor documentation updates.
3dtopos: Fixed bug which resulted in station names and coordinates getting mismatched; output now defaults to current directory.
diffpos: list added and deleted stations in sorted order; better error reporting.
3dtopos: removed hardcoded limit on number of stations (was 100000); better error reporting.
Further tweaks to charset handling - look at LC_* as well as LANG; Check GUI codepage under MS Windows.
cavern: Allow *copyright/*date/*instrument/*team/*title between *begin and *export.
cavern: Fixed typo which prevented *instrument from being recognised as a valid command.
cavern: removed option to produce ascii .3d files.
cavern: on error, remove any existing .inf file for consistency with .3d and .err files.
cavern: interleaved nosurvey data style now works; nosurvey legs now count as a "use" of a fixed point.
cavern: give at most 5 warnings about use of any particular deprecated feature. Otherwise processing an old dataset just gives an avalanche of warnings which buries any other warnings or errors.
cavern: implemented `*infer equates'.
aven: if a .3d file is truncated or corrupted part way through, aven would previously load part of it without complaint. Fixed to complain and not load anything.
printwin: fixed problem where it hung when waiting for input.
print*: Added --output command line option to override the output setting in the .ini file (ignored by printwin).
.3d files now store prefixes for legs (the prefix is taken from the "from" station of the leg); Station names and leg prefixes in .3d files are now stored compressed. Despite now storing prefixes for legs, .3d files are now typically 25%-33% smaller than before.
xcaverot/caverot: Added --survey command line option which restricts the view to a sub-survey in the .3d file. e.g.: "caverot --survey 161.dream all.3d"
(MS Windows version): added explorer bindings for sorterr.
cavern/xcaverot/sorterr: fixed --help output to include long options.
Minor documentation updates.
cavern/3dtopos: cavern no longer produces .pos files - they're mostly useful for hand plotting and are larger than the corresponding .3d files so most of the time they slow processing and then clutter up the disk. A new utility 3dtopos produces a .pos file from a .3d file, and has the added benefit that it sorts names with numbers in numerically (i.e. 2 before 10).
diffpos: the arguments can now be .pos or .3d files, or one of each.
cavern: improved parsing of unquoted *include/*title strings - used to end at the first literal space; now they end at the first BLANK character (space, tab, and comma by default). So the odd case of an unquoted string with commas or tabs will require quotes to be added.
All versions have been missing RTF, text, and PostScript versions of the documentation in the previous 2 prereleases.
cavern: Fixed articulation code wasn't quite.
cavern: an empty label was being added to the .3d file for a station fixed with standard deviations. Such labels are also now ignored by img on read-in.
(MS Windows version): Fixed "Open" on a .3d file to open in aven rather than converting to a DXF. "Convert to DXF" now appears as a separate menu item.
cavern: Fixed bogus errors about matrix not being positive definite.
cavern: Fixed bug in articulation point code which could result in a traverse "exploding" in certain situations (introduced in 0.95).
cavern: Check for chunks of survey not connected to a fixed point is now done earlier on (which simplifies quite a bit of the network code).
xcaverot: Disabled "legs" and "surface" buttons in --pda mode - they make the button bar too wide.
Covariance matrices are symmetric - now only store 6 of the 9 entries. Typically uses 10% less memory and is 15% faster.
caverot: adjust to speed of machine/size of survey on initial draw, rather than on first action from user.
(MS Windows version): now handle oe-ligatures.
(Unix version): discover character set by looking at $LANG.
(MS Windows version): discover character set from Windows.
Transliterate accented characters that can't be represented in the current character set.
Added support for Latin9 (iso-8859-15) character set.
printps/printpcl/printwin: Improved handling of accents on printouts.
aven: added optional grid; dashed surface survey now the default; Indicators moved to submenu of View menu.
aven: reporting errors in a message box wasn't working (wxWindows bug).
cavern: fixed *entrance - it was trying to insist its argument was a survey, not a station.
cavern: a leg with the same station at both ends now causes an error rather than just a warning.
cavern: added station name to "station equated to itself" message.
cavern: allow interleaved data formats.
sorterr: new utility for sorting .err files by various criteria.
xcaverot: buttons now size to widest label; added --pda switch to turn off less useful buttons for use on small screens (such as the ipaq PDA).
Unchanged from 0.97-prerelease7.
Messages relating to command line options are now translatable.
(MSDOS versions): now supply self-extracting zip archives.
(MS Windows version): after running cavern, wait for a key press before closing the window.
cavern: Very quiet mode (-qq) now produces absolutely no output if there are no errors or warnings.
(MS Windows version): aven: if there are problems opening the message file, report them in a message box rather than printing text which the user will never see.
cavern: invalid data lines weren't being counted, so you'd get incorrect line numbers reported for further errors and warnings.
cavern: Added a SPLAY flag for indicating splay shots in chambers and large passages.
extend: ignore surface legs and splay legs; preserve duplicate flag on extended legs.
print*: if surface data isn't being plotted, ignore surface survey stations too, and select page layout based on underground data only.
(MS Windows version): get default language from Windows.
cavern: added *entrance command for indicating cave entrances.
Added "surface", "underground", "exported", "fixed", and "entrance" station flags to 3d format.
(DOS version): caverot: fixed bug Brian Clipstone reported where caverot would lock up when trying to plot a label off-screen.
xcaverot/caverot: tweaked sense of a few controls to be consistent with each other and with aven.
Strip leading '\' from station names read from old .3d files.
cavern: Better reporting of error stats involving a station fixed with errors.
aven: allow highlighting of fixed, exported, and entrance stations.
survex: conversion wrapper now only creates __svxtmp.svx file if it has to - simple cases (such as "survex example.svx") don't need one; also always print warning that user should be using cavern instead.
Minor updates to documentation.
Survey stations names are no longer displayed with a leading '\' - this doesn't make sense now that root is deprecated, and didn't make much sense before to be honest.
cavern: *fix with two standard deviations (horizontal and vertical) was being rejected - fixed.
cavern: Fixed bug with station "\" appearing in the .err file for a station fixed with error estimates.
(non-Unix versions): remove path and extension and lower-case program name for use in error reporting.
(MS Windows version): added documentation overview page to HTML help.
Removed 255 character limit on station names in .3d and .3dx files.
caverot: overlapping label code wasn't allowing enough for vertical overlap.
cavern: after a bad *data command, ignore survey data until the next valid *data command.
printdm/printpcl: exit cleanly if bitmap font file is missing.
cavern: give a more helpful error on empty "*export" or "*prefix".
xcaverot: Fixed display of surface legs and related minor issues.
print*: Fixed handling of surface legs; `-S' now recognised as a short-form for `--surface'.
Added test of *solve command.
cavern: Added commands *date, *team, *instrument, *copyright - currently these are ignored, but they provide a place to put data when importing/exporting, and will be processed in future versions.
(MS Windows version): aven updated to same codebase as Unix version.
Updated Portuguese and German translations.
aven: Accents now work in display; suppress "wxstd" warning box for English; speed improvements; redesign of indicators; rescale by dragging scalebar; allow surface legs to be hidden (they are by default); now defaults to plan view; depth bar labelling improved; added caverot-like handling of flat surveys (so output from extend is locked flat).
cavern: Complain if the same name is used for a survey and a station.
cavern: Added --warnings-are-errors command line option.
caverot/xcaverot: Middle button now tilts cave by dragging rather than toggling plan/elevation.
caverot: continue setup in background while help page is displayed; "R" (Reverse Rotation) now only affects the auto-rotation - it used to affect "C", "V", "/", and "'".
cavern: unused fix point warnings now work for stations fixed with error estimates; added test cases for this.
testsuite: Enhanced many existing tests to check for warnings.
Fixed to build on Solaris with Sun's compiler.
Minor corrections to documentation and man pages.
cavern: report *export errors at the file and line where the *begin for the survey involved was as that's much more useful.
cavern: allow "-" in station names by default.
(Unix version): aven: Internationalised; Fixed serious drawing bug causing incorrect rendering and segfaults; Scale bar now draggable; Depth bar tidied up; Orientation menu changes; Menu accelerators fixed; Status bar disabled (various continuing problems and it doesn't really convey much useful info anyway); About box fixes; Fixed crashes on mouse actions when no survey loaded; Improved labelling of scale bar and indicators.
Created Swiss German and "German German" sub-versions of German translation.
(DOS version): caverot: fixed slight underallocation of memory which probably caused the bug Brian Clipstone reported.
cavern: Improved reporting of missing *export-s; added 2 more *export tests.
No longer trap SIGINT (Ctrl-C) or SIGTERM (Ctrl-\ on Unix) as we can't do anything useful.
Removed support for really old language names ("fren", "germ", "ital", etc) - use "fr", "de", "it", etc instead.
(RISC OS version): support a few extra accents in messages.
"Syntax" in command-line help messages now translated.
cad3d: Fixed output from `--help'; -e, -D, -S short options now work; fixed infinite loop bug.
(Unix version): aven: leaving "about" box no longer causes segfault; toggle status bar now works; N/S/E/W selects view rather than moving cave; window close now works; now have ticks on appropriate menu items; fixed problems with rendering (some legs missing!); 3d file specified on command line now loaded; fixed occasional hangs; fixed terrible slowness during rotation; implemented indicators; various other bugs fixed.
Updated translations: pt de it (and fr partially)
Added tests for most commands and various other cases.
cavern: fixed *case (correct args are PRESERVE/TOUPPER/TOLOWER) and upper/lower were swapped.
Documentation brought more up-to-date.
caverot/xcaverot: fix missing end of list marker for surface data which typically resulted in a few extra bogus surface legs appearing.
printer drivers: fixed .ini file reading routine (bug introduced in 0.97-prerelease 1).
printps: postscript file meta information now includes the date of creation, and also the name of the user running printps (Unix only).
printer drivers: improved reporting of problems with print.ini files.
(MSDOS version): fallback DPMI provider and floating point emulator were missing in 0.97-prerelease1.
Better internationalisation - select localised system messages using setlocale().
extend: fixed bug which resulted in bogus output (added regression test); produce binary rather than ASCII .3d output.
cavern: don't report error stats for articulating traverses.
(UNIX version): `make uninstall' now removes the HTML documentation.
(UNIX version): printer drivers: Look for /etc/survex/print.ini rather than <prefix>/share/survex/myprint.ini
cavern: added warning that use of ROOT character ('\' by default) is deprecated; updated documentation to mention this.
cavern: added *export command to allow scope of station names to be limited. If *export is never used, behaviour is as before.
cavern: added *flags command to allow surface surveys and duplicate surveys (to be ignored when calculating the total survey length) to be indicated.
new version of 3d file format which can store flags and is slightly more compact. NB New programs can load old .3d files, but old programs can't load new .3d files.
caverot/xcaverot: allow surface legs to be hidden (they are by default)
cavern: compass can be omitted on legs in diving data to indicate a plumbed leg. In this case the tape and depth gauge readings are combined to give the length of the leg.
cavern: *begin/*prefix reentry warning now gives the original location as a separate warning so smart editors will allow you to click on it to jump to that file and line.
printer drivers: put "http://www.survex.com/" on printouts in case someone who gets a printout wants to know more about Survex.
cavern: added easting, northing, altitude added as prefered aliases for dx, dy, dz.
cavern: bug fix: "*prefix \" or "*begin \" would cause an internal error.
xcaverot: "load" button now works; bearing always shown in range 0-360; / and ' now tilt cave; `u' and `d' now switch to view from above/below; shift-ed keys now work; `o' now turns off non-overlapping labels; `ctrl-L' toggles display of survey legs.
caverot: n/s/e/w/u/d now work as in xcaverot - the previous functions they had weren't actually useful; if memory is really tight, disable non-overlapping labels rather than dying with an error.
prefer balanced quotes (`...') to unbalanced ('...') in messages.
cavern: file reading errors now treated as fatal; unattached survey error now fatal.
survex: syntax errors in command line arguments now fatal.
cavern: if there are errors, don't produce output files.
cavern: bug fix: trying to report certain errors in really long lines could cause an internal error.
3dtodxf: renamed to cad3d since it can now produce DXF or sketch format.
aven: rewritten to use wxwindows (under Unix only so far).
printwin: new native Microsoft Windows printer driver.
(MS Windows version): new installation wizard.
Use double precision floating point to pass numbers to/from .3d file reading routines to avoid rounding problems.
cavern: change of terminology - use "reading" instead of "datum", since datum more usually means a map datum in surveying.
(MSDOS and MS Windows versions): fixed bug in message file handling introduced in 0.96-prerelease 1 - symptoms: messages incorrectly looked for in current directory, or just printing "???" and exiting.
cavern: attempting to *include a non-existent file used to complain: "In file included from example.svx:31:" / "cavern: Couldn't open data file 'bad.svx'" - now complain "example.svx:31: Couldn't open data file 'bad.svx'".
xcaverot: cursor keys now move the 3D centre of rotation rather than just the position of the survey in the window.
cavern (RISC OS version): "is this a directory" test would never say "yes".
caverot: (MSDOS version) cursor keys and delete had stopped working (due to changes in allegro graphics library) - fixed.
xcaverot: Zoom in and out with keyboard now behaves exactly like clicking on buttons; Removed unused "select" button; Fixed significant memory leak.
aven: (MS Windows version) Mark Shinwell has written a Microsoft Windows version of aven, which is better in almost every way than the directx version of caverot (and we're working to fix the few shortfalls), so we've shelved directx caverot and are now including aven instead with the MS Windows version.
caverot: DirectX version for Microsoft Windows.
caverot: (MSDOS version) 640x480 doesn't work under NT either, but 320x200 does so default to that instead.
caverot: --mode-picker option now listed by --help.
caverot: (MSDOS version) --mode-picker now recognised anywhere on command line (had to be last previously).
caverot: (MSDOS version) messages from Allegro library now internationalised.
caverot: (MSDOS version) don't try to get 800x600 if running under NT - try 640x480 instead.
