Fri Nov 16 23:10:29 2007  Jiri (George) Lebl <jirka@5z.com>

	* gtkextra/gtkplot.[ch]: add freeze/thaw functions since otherwise
	  we may hang and eat all memory on recalculating ticks needlessly
	  when changing both range and ticks.

	* src/graphing.c: use freeze/thaw to avoid hangs and huge memory
	  leaks.  On parametric plots, squish the graph a little and move
	  the legend below the plot.

	* NEWS: update

Fri Nov 16 00:50:48 2007  Jiri (George) Lebl <jirka@5z.com>

	* lib/calculus/sums_proucts.gel: increase default sum and product
	  tries to 10000, since 200 was just not cutting it.

Thu Nov 15 23:30:51 2007  Jiri (George) Lebl <jirka@5z.com>

	* src/calc.c: Much nicer pretty printing of matrices.  Rather
	  than using tabs, use commas and align elements successive rows.
	  Both nicer, more readable (when MixedFractions is on) and more
	  compact way of seeing matrices.  Yay!

	* src/lexer.l: drop the tab support for entering matrices.  Not only
	  was it stupid, it didn't work on the command line

	* src/funclib.c: fix print, printn and display functions to not follow
	  the line length limits like normal output

	* src/calc.c: when pretty printing a matrix, only print the leading
	  newline if we are not in fact on the start of a line

	* configure.in: check for svn rather than cvs to add extra warnings

	* src/gnome-genius.c: make is_uri static to avoid a warning

	* help/C/genius.xml: update the manual

	* NEWS: update

Thu Nov 15 18:39:06 2007  Jiri (George) Lebl <jirka@5z.com>

	* src/Makefile.am: add nullspacetest.gel

Wed Nov 14 20:13:29 2007  Jiri (George) Lebl <jirka@5z.com>

	* src/matop.c: fix possible memory corruption in the gauss
	  routine

	* src/matrixw.c: slight optimization to not copy zeros

	* src/funclib.c, lib/linear_algebra/*.gel: Implement NullSpace
	  and PivotColumns internally for speed.

	* src/gnome-genius.c: remove some unused vars

	* src/geniustests.txt, src/nullspacetests.txt: add tests for
	  PivotColumns and NullSpace

Wed Nov 14 04:15:49 2007  Jiri (George) Lebl <jirka@5z.com>

	* lib/linear_algebra/*.gel: OrthogonalComplement is with respect
	  to Hermitian product just like everything else.  Also
	  handle null as empty matrix/subspace in more places.

Wed Nov 14 03:45:42 2007  Jiri (George) Lebl <jirka@5z.com>

	* src/matop.c, src/symbolic.c, src/mpwrap.[ch], src/calc.c,
	  src/funclib.c, src/eval.c: Significantly improve both
	  memory usage and speed in matrix multiplication and to some degree
	  Gaussian elimination in case there are a lot of zero entries.

	* src/geniustests.txt: update

Tue Nov 13 23:48:25 2007  Jiri (George) Lebl <jirka@5z.com>

	* src/matrixw.[ch], src/calc.c, src/funclib.c, src/matop.c,
	  src/symbolic.c, src/compil.c, src/eval.c: Optimized / cleaned up
	  certain matrix operations a tiny bit.  Consistently traverse
	  matrices row wise.

	* src/funclib.c, src/eval.c: Fixed and slightly optimized IsIn,
	  it used to bomb if the first argument was a matrix, and it
	  used to think that the object "true" is equal to any number,
	  and further it didn't see a difference between numbers of
	  different types (float vs. integer).  This fixes also Intersection,
	  Union, MakeSet and SetMinus.  Also added IsSubset.  Also fixed
	  symbolic tree comparison for matrices.

	* src/mpwrap.c: When printing out a floating point number, make sure
	  to append ".0" to the end to distinguish it from an integer

	* src/geniustests.txt:  updated tests, added many new tests.

	* help/C/gel-function-list.xml: updated

	* NEWS: update

Sun Nov 11 03:17:49 2007  Jiri (George) Lebl <jirka@5z.com>

	* src/gnome-genius.c: translate the author fields in the about box
	  and set the program name correctly

Sun Nov 11 03:07:04 2007  Jiri (George) Lebl <jirka@5z.com>

	* src/funclib.c: there was a stupid string to translate

Sun Nov 11 00:14:04 2007  Jiri (George) Lebl <jirka@5z.com>

	* pixmaps/Makefile.am: add genius-graph.png to EXTRA_DIST

	* src/funclib.c: Implement DividePoly to divide polynomials
	  using long division.  This was one of those things that
	  I set aside to do "tommorrow" and it took close to a decade.

	* help/C/gel-function-list.xml: document DividePoly

	* configure.in: require GTK+ 2.4 (not 2.3.5 as previously)

	* NEWS: update

Sat Nov 10 16:58:14 2007  Jiri (George) Lebl <jirka@5z.com>

	* src/gnome-genius.c: migrate to GtkFontButton and add website addy
	  to about box

Sat Nov 10 16:22:09 2007  Jiri (George) Lebl <jirka@5z.com>

	* src/gnome-genius.c: optionally use GtkAboutDialog if we have GTK
	2.6 and higher

	* src/gnome-genius.c, src/genius.c, src/Makefile.am: better checking
	if we are in the development directory and if so, don't init binreloc
	and use the local lib.cgel

Sat Nov 10 13:51:26 2007  Jiri (George) Lebl <jirka@5z.com>

	* src/graphing.c: fix fit dependent axis zoom for parametric plots

	* src/dict.[ch], src/gnome-genius.c, src/eval.c: Add names to
	  contexts and print these when showing local variables so that you
	  can see the "backtrace".  Also the display of vars is slightly
	  nicer now.

Thu Nov 08 00:51:16 2007  Jiri (George) Lebl <jirka@5z.com>

	* src/gnome-genius.c, src/genius.c, src/funclib.c, src/plugin.c,
	  src/lexer.l, src/binreloc.[ch], acinclude.m4, src/Makefile.am:
	  add and use Binreloc code from autopackage to allow relocatable
	  executables.  Slightly massaged the code/auto* stuff to make it
	  work.

Mon Nov 05 01:31:51 2007  Jiri (George) Lebl <jirka@5z.com>

	* Makefile.am: add the INSTALL.MacOSX file to EXTRA_DIST

Mon Nov 05 00:15:09 2007  Jiri (George) Lebl <jirka@5z.com>

	* src/calc.[ch], src/mpwrap.[ch], src/funclib.c, src/genius.c,
	  src/gnome-genius.c, src/structs.h src/geloutput.[ch]:  Implement
	  OutputChopExponent and OutputChopWhenExponent parameters.  These
	  will chop small numbers if they appear near large numbers.

	* src/gnome-genius.c: try to use G_DIR_SEPARATOR more just in case
	  someone will start porting genius

	* help/C/*.xml: update documentation for chopping

	* src/geniustests.txt: add tests for chopping

	* README, NEWS: update

Sun Nov 04 02:37:58 2007  Jiri (George) Lebl <jirka@5z.com>

	* src/graphing.c: unswap x and y.  They are now in correct positive
	  orientation in gtkextra.

	* src/gnome-genius.c, pixmaps/gnome-graph.png: add a simple "logo"
	  to the about box

	* NEWS: update

Sat Nov 03 20:51:37 2007  Jiri (George) Lebl <jirka@5z.com>

	* src/graphing.c: Use -10 to 10 for all default ranges.  Much better
	  than PI, that was stupid.  Set minimum plot window to 1e-10 and
	  enforce it to avoid errors with computing ticks leading to
	  hanging behaviour.

	* gtkextra/*: copy new files from cvs version of gtk extra except
	  for gtkpslot which is broken, so keep our old version which works

	* gtkextra/gtkplot3d.[ch]: fix up the axis mess

	* src/graphing.c: use the new gtk extra stuff.  Produces nicer
	  plots on screen.  Initial patch was by Sebastian Dröge
	  <slomo@circular-chaos.org>

2007-11-03  Sebastian Dröge  <slomo@circular-chaos.org>

	* configure.in:
	* src/Makefile.am:
	* src/gnome-genius.c: (get_source_language_manager), (new_program):
	Optionally allow to use GtkSourceView2 instead of GtkSourceView1.
	Version 2 is preffered if available, otherwise version 1 will be used.

2007-11-03  Sebastian Dröge  <slomo@circular-chaos.org>

	* Makefile.am:
	* configure.in:
	* help/omf.make:
	Add --disable-scrollkeeper and --disable-update-mimedb options to
	configure to skip building the scrollkeeper and mime database on
	make install. The files generated by this must not be shipped by
	binary packages and having this options makes it easier to package
	genius.

Wed Oct 31 10:43:25 2007  Jiri (George) Lebl <jirka@5z.com>

	* gtkextra/*: remove gtkplotdtriangle.[ch]: they're not needed and
	  have a bad license.

Fri Oct 26 02:16:23 2007  Jiri (George) Lebl <jirka@5z.com>

	* src/calc.[ch], src/eval.[ch], src/genius.c, src/gnome-genius.c:
	  Implement maximum node checking.  If the limit is hit you are
	  given a chance to interrupt the current program.  Only in the
	  GNOME version.  Add this to the Properties dialog.

	* src/dict.c: Fix large performance problem on returning from a deep
	  recursion by not doing a stupid assert

	* help/C/genius.xml: document max_nodes

Thu Oct 25 15:22:16 2007  Jiri (George) Lebl <jirka@5z.com>

	* src/inter.c: fix command line editting.  readline docs are
	  horrible! (and readline is horrible)

	* src/gnome-genius.c: fix strange printing of locals among globals

Thu Oct 25 13:47:40 2007  Jiri (George) Lebl <jirka@5z.com>

	* src/gnome-genius.c, src/dict.[ch]: Implement showing of all user
	  variables even during runtime.  Shows even local variables if some
	  function is currently being executed.  Allows better debugging

	* src/gnome-genius.c: fix show full answer leak and fix running it
	  during runtime.

	* configure.in: bump version

	* help/C/genius.xml: update docs a bit, add some more info on the gui
	  part of genius.

Tue Oct 23 17:14:25 2007  Jiri (George) Lebl <jirka@5z.com>

	* src/funclib.c: positive and nonnegative matrixes obviously can't
	  have complex entries so return false

Tue Oct 23 16:23:53 2007  Jiri (George) Lebl <jirka@5z.com>

	* src/funclib.c: add IsMatrixPositive and IsMatrixNonnegative

	* help/C/gel-function-list.xml: add docs for the above

Tue Oct 23 16:04:56 2007  Jiri (George) Lebl <jirka@5z.com>

	* src/funclib.c: add "version" function for checking the version

	* help/C/gel-function-list.xml: add doc for version

Tue Oct 23 15:42:03 2007  Jiri (George) Lebl <jirka@5z.com>

	* src/funclib.c, src/funclibhelper.cP: Add IsZero and IsIdentity for
	  checking if a matrix is zeros or an identity

	* help/C/gel-function-list.xml: add docs for the above

Tue Oct 23 13:57:03 2007  Jiri (George) Lebl <jirka@5z.com>

	* src/gnome-genius.c: on errors don't print the whole filename for
	  opened files, just the displayed name

	* src/gnome-genius.c: add Ctrl->R for "Run"

Tue Oct 23 13:33:42 2007  Jiri (George) Lebl <jirka@5z.com>

	* lib/linear_algebra/linear_algebra.gel: slightly optimize
	  PivotColumns by removing unnecessary separators

	* src/matop.c, src/funclib.c: when computing det be smart about
	  matrices in rref form.  This way once we make a matrix rref,
	  we can use det to check if it is singular very quickly.  Also
	  set the rref flag on identity matrices.

Tue Oct 23 12:28:56 2007  Jiri (George) Lebl <jirka@5z.com>

	* src/gnome-genius.c: add "save all unsaved" menu item, fix the save
	  as dialog, and add confirmation on closing unsaved things.

Tue Oct 23 11:33:56 2007  Jiri (George) Lebl <jirka@5z.com>

	* lib/functions/numerical.gel: remove IsGaussianInteger, we already
	  have IsGaussInteger alias IsComplexInteger

	* help/C/gel-function-list.xml: updates and fixes

Tue Oct 23 10:51:24 2007  Jiri (George) Lebl <jirka@5z.com>

	* src/gnome-genius.c: better logic for figuring out something is a
	  URI

Mon Oct 22 21:39:42 2007  Jiri (George) Lebl <jirka@5z.com>

	* src/gnome-genius.c: recognize uris on the command line
	  and handle them correctly

Mon Oct 22 19:38:03 2007  Jiri (George) Lebl <jirka@5z.com>

	* src/gnome-genius.c: whack the old gtk file selection stuff,
	  I'm tired of fixing bugs in two versions of code.  Consistently
	  have uri's around as program->name internally.  Fix opening
	  files without specifying full path on command line.

	* configure.in: require at least gtk+ 2.3.5

Tue Oct 16 11:05:32 2007  Jiri (George) Lebl <jirka@5z.com>

	* src/gnome-genius.desktop.in: hmmm, Calculator;Utility; also fits
	  the bill.  Makes the menu entry appear twice at least in ubuntu.
	  ... hmmm oh well.  The default menu setup in gnome must be a little
	  braindead and uses too simple queries.

	* help/C/genius.xml: added Accessories to list of possible submenus

Tue Oct 16 10:53:33 2007  Jiri (George) Lebl <jirka@5z.com>

	* src/gnome-genius.desktop.in: change Office to Education as per
	  the vfolder spec (that's still somewhat wrong, but unfortunately
	  it is as close to standard behaviour as we get).  Also notice
	  that the Scientific category was wrong.  "Science" is correct
	  as per spec.

	* help/C/genius.xml: update the manual for where to find the icon.

Sun Oct 14 10:10:11 2007  Jiri (George) Lebl <jirka@5z.com>

	* src/gnome-genius.c: add Adrian E. Feiguin to the authors
	  list in the about box

Sun Oct 14 09:40:59 2007  Jiri (George) Lebl <jirka@5z.com>

	* src/gnome-genius.c: I finally found the culprit behind some of
	  the initial GEL implementations of standard library so I added
	  him, Nils Barth to the authors list.

Sun Oct 14 02:33:43 2007  Jiri (George) Lebl <jirka@5z.com>

	* help/C/*: update the documentation a bit more.  Make it almost one
	file only by inlining all the things done as separate entities
	before, that was a nightmare to edit.  Only the function list
	and the legal nonsense is left separate.

Sat Oct 13 10:38:49 2007  Jiri (George) Lebl <jirka@5z.com>

	* help/C/*.xml: minor fixes

Sat Oct 13 09:42:33 2007  Jiri (George) Lebl <jirka@5z.com>

	* help/C/gel-variables.xml: add more on scope of variables and
	  other minor fixes.
