path: root/libs/cassowary/ChangeLog

Fri Mar 18 15:41:00 2005  Taybin Rutkin <taybin@earthlink.net>
	* Removed ClSet.h, ClMap.h.
	* ClReader.l includes ClReader.cc.h instead of ClReader.hh.  The
	difference between yacc and bison.
	* Various changes to fix compliation.

Wed Jan 29 21:36:15 2003  Taybin Rutkin <trutkin@physics.clarku.edu>
	* Updated to work with g++ 3.x compilers.
	* More direct use of STL.
	* Removed C wrappers

Sun Mar 12 13:40:44 2000  Greg J. Badros  <gjb@cs.washington.edu>

	* guile/cassowary_scm.cc: Give docstrings as arguments

	* guile/cl-snarf.h: Added docstring as an argument to CL_PROC to
	be like the revised Scwm documentation extraction system.

Sat Feb 12 20:34:55 2000  Greg J. Badros  <gjb@cs.washington.edu>

	* Makefile.am: Added GTL.h.patch to EXTRA_DIST

Sat Feb 12 20:31:47 2000  Greg J. Badros  <gjb@cs.washington.edu>

	* c++/ClSimplexSolver.cc, c++/ClSimplexSolver.h: Drop
 	ExternalResetStayConstants, make ResetStayConstants() public.
  	Test _fResetStayConstantsAutomatically before doing so in
 	Resolve().  Use _fAutosolve instead of _fOptimizeAutomatically.
	Drop DisplayObjective (wasn't defined anyway).  Drop field
	_fOptimizeAutomatically (use _fAutosolve from parent, instead).

	* guile/cassowary_scm.hpp, guile/cassowary_scm.cc: Drop extra
 	include of guile/gh.h

	* guile/cassowary_scm.cc: Added `cl-set-auto-solve!',
	`cl-set-auto-reset-stay-constants!'

Sat Jan 29 17:45:32 2000  Greg J. Badros  <gjb@cs.washington.edu>

	* configure.in (CASSOWARY_VERSION): Bump to 0.55.

Sat Jan 29 17:43:05 2000  Greg J. Badros  <gjb@cs.washington.edu>

	* c++/ClSimplexSolver.cc (Resolve): Do not comment out
	"ResetStayConstants()" as Beurivé had done.  This was resulting in 
	quirky behaviour whereby the windows were "rubber-banding" back to 
	where they were at the start of an interaction (e.g., if I push a
	window out of the way to the left with another window, as I move
	the pushing window back to the right, the other window comes back
	to the right with the pushing window).  Maybe that's desirable
	behaviour in some instances, but it's not the behaviour we
	document and sure feels weird to me.

Sat Jan 29 17:38:43 2000  Greg J. Badros  <gjb@cs.washington.edu>

	* java/sym.java, java/parser.java, java/Yylex.java: Added -- these 
	are created by JavaCUP which I don't want to be necessary for
	building.

Mon Jan 24 09:34:20 2000  Greg J. Badros  <gjb@cs.washington.edu>

	* c++/ClSymbolicWeight.h: Set SymbolicWeight multiplier to
	1000000, not 10000 (A.Beurivé)

	* c++/ClSimplexSolver.h, c++/ClSimplexSolver.cc: Added
 	ChangeStrength, ChangeStrengthAndWeight, ChangeWeight,
 	DisplayObjective, ExternalResetStayConstants fns.
	(RemoveConstraintInternal) Avoid picking the objective row when
	removing a constraint.  (Optimize) Pick any negative row to avoid
	unending pivots [I think this is a work-around to avoid having to
	implement Bland's anti-cycling rule... maybe I should just do
	that, though].  (A.Beurivé)

Thu Dec 16 11:12:34 1999  Greg J. Badros  <gjb@cs.washington.edu>

	* java/Makefile.am: Put SUBDIRS demo cda back in since they
	compile now.

	* scripts/recreate-symlinks: Update with links to ../../EDU from
	demo directories for Java code.  Use ln -sf, not just ln -s, to avoid 
	warnings.

	* Makefile.am (EXTRA_DIST): Include scripts/recreate-symlinks

	* configure.in: Run recreate-symlinks script.

Wed Dec 15 18:07:27 1999  Greg J. Badros  <gjb@cs.washington.edu>

	$CC.  Eliminate the --enable-permissive flag since it is no longer 
	necessary.

Mon Dec 13 15:56:19 1999  Greg J. Badros  <gjb@cs.washington.edu>

	* java/Yylex.java: Added, from Will Portnoy.

	* java/ClReader.cup, java/ClReader.lex: Latest version from Will,

Mon Dec 13 15:55:59 1999  Greg J. Badros  <gjb@cs.washington.edu>

	* c++/Makefile.am: Remove ClReader.cc -- why did I add this

	* smalltalk/A991206.dat: New image from Alan. Include correct
	version of code for "ClSimplexSolver removeConstraint:" to fix bug
	when deleting constraints with weights other than 1.  Also
	disallow invalid comparisons between symbolic weights and floats.
	Replace expressions "x clApprox: 0.0" with "x clApproxZero", which
	works correctly for both symbolic weights and floats.

	* smalltalk/*.st:  Added from Alan.

Mon Nov 29 16:23:06 1999    <gjb@cs.washington.edu>

	* configure.in: Bump to version 0.54, added -lGTL to GTL_LIB even

Mon Nov 29 10:52:49 1999  Greg J. Badros  <gjb@cs.washington.edu>

	* c++/Makefile.am: Added use of AM_CONDITIONAL
	CL_BUILD_STATIC_LIBRARY;  only buile libcassowary.a if that option 
	was selected.

	* guile/Makefile.am (libconstraints_la_LIBADD): Added @GTL_LIB@ to 
	make the guile library work with the FD-enabled version of the library.

Sat Nov 27 16:11:10 1999  Greg J. Badros  <gjb@cs.washington.edu>

	* configure.in: Invert sense of --enable-guile-build and call it
	--disable-guile-build;  build guile wrapper automatically if
	guile-config works.

Sat Nov 27 15:20:03 1999  Greg J. Badros  <gjb@cs.washington.edu>

	* configure.in: Use an AM_CONDITIONAL for CL_BUILD_FD_SOLVER, not
	an AC_DEFINE.  Also, remove duplicate AC_SUBST of GTL_LIB, and fix 
	AM_CONDITIONAL of CL_BUILD_TESTS.

Sat Nov 27 15:19:20 1999  Greg J. Badros  <gjb@cs.washington.edu>

	* c++/Makefile.am: Try separating out FD stuff better, and use
	CL_BUILD_FD_SOLVER AM_CONDITIONAL to control dependence on that
	code.

	* c++/config.h.in: Drop CL_BUILD_FD_SOLVER; it's now an
	AM_CONDITIONAL instead of a define.

Wed Nov 24 15:40:27 1999  Greg J. Badros  <gjb@cs.washington.edu>

	* c++/ClSimplexSolver.cc: Fix typo in a throw message.

	* java/ClReader.lex, java/ClReader.cup: Added -- code by Will
	Portnoy for adding a parser to the Java implementation.  Untested, 
	and an early version that he emailed me.

Tue Nov 16 17:34:00 1999  Greg J. Badros  <gjb@cs.washington.edu>

	* java/ClTestColumns.java, java/ClTests.java: Put in the cassowary 
	package, instead of importing cassowary.*;  jikes needed this
	(discovered during testing of java-ml work).

Sat Nov 13 11:43:48 1999  Greg J. Badros  <gjb@cs.washington.edu>

	* java/Timer.java (Timer): Remove return type from Timer()
	constructor (jikes caught the bug when I used this as a test case
	for my java-ml work).

Sun Oct 24 13:17:14 1999  Greg J. Badros  <gjb@cs.washington.edu>

	* configure.in: Updated version to 0.53, generate
	smalltalk/Makefile from Makefile.am.

 	Duret-Lutz for the patch!

Thu Sep 30 08:17:16 1999  Greg J. Badros  <gjb@cs.washington.edu>

	* c++/ClFDSolver.cc: Added missing #include <stdarg.h> -- Thanks

Sun Sep 26 13:43:12 1999  Greg J. Badros  <gjb@cs.washington.edu>

	* c++/Makefile.am (libcassowary_la_LDFLAGS): Added -version-info
 	flag to make libcassowary.so.0.0.1, instead of .0.0.0

	* c++/ClSimplexSolver.h, c++/ClSimplexSolver.cc: Replace
 	_editVarMap with _editInfoList, a list.  Make ClEditInfo class
 	contain the variable since its no longer stored as values in a
 	hash where the key is the variable.  Drop the index from
 	ClEditInfo.  Rename ClVarToEditInfoMap to ClEditInfoList.

Sun Sep 19 14:44:00 1999  Greg J. Badros  <gjb@cs.washington.edu>

	* c++/ClTests.cc (multiedit2): Added this new test to check nested
 	edits that share an existing variable better.  This tests the fix
 	for the ScwmButtons auto-orientation seg-fault bug in Scwm.

	* c++/ClBug0.cc: Added comment re: new bug fix.

Sat Sep 18 22:31:54 1999  Greg J. Badros  <gjb@cs.washington.edu>

	SMOBs conditioning on HAVE_SCM_MAKE_SMOB_TYPE_MFPE.

Wed Sep  8 20:03:25 1999  Greg J. Badros  <gjb@cs.washington.edu>

	* cassowary.spec.in: Bump to release 8

	* cassowary-nofd.spec2.in: Bump to release 2.

Wed Sep  8 19:43:53 1999  Greg J. Badros  <gjb@cs.washington.edu>

	* c++/Makefile.am: Drop building of config-inline.h -- let
	configure handle that-- this was causing a double-build
	(!!!ugh!!!) of Cassowary when building from RPMs, e.g.

	* GTL.spec.in: Use install-strip target.

Tue Sep  7 23:34:49 1999  Greg J. Badros  <gjb@cs.washington.edu>

	* configure.in, Makefile.am: use cassowary-nofd.spec2.in

	* cassowary-nofd.spec2.in: Renamed from cassowary-nofd.spec.in,
	since having two *.spec files in the top level upsets rpm (it cats 
	them together and then gets confused by the double .spec file).

	* cassowary-both.spec.in: Added-- rpm doesn't support two %build
	tags (one for a subpackage), but if it did, this is what the
	corresponding .spec file might look like.

Tue Sep  7 23:02:26 1999  Greg J. Badros  <gjb@cs.washington.edu>

	* Makefile.am: Added cassowary-nofd.spec to EXTRA_DIST,
	bin_SCRIPTS = cassowary-config.  Added dist-nofd target, and
	supporting targets.

	* cassowary.spec.in: Bump to 7, provide virtual package, install
	%{prefix}/bin/* (for cassowary-config script).

	* configure.in: Added CASSOWARY_VERSION variable, create
	cassowary-config, cassowary-nofd.spec

	* cassowary-config.in, cassowary-nofd.spec.in: Added

Mon Sep  6 21:40:58 1999    <gjb@cs.washington.edu>

	* cassowary.spec.in: Use install-strip target to remove debug
	symbols and save disk space.  Remove %{prefix}/doc/* from the
	%files list as they are in the %doc listing already.

Mon Sep  6 12:25:14 1999   Greg J. Badros  <gjb@cs.washington.edu>

	* cassowary.spec.in: Use --host=alpha-linux on that platform
	(using an %ifarch). Bump to release 6.

	* GTL.spec.in: Fix the ./configure line for alpha platform (was
	missing "--" before the "prefix" option). Bump to release 2.

	* c++/ClSymbolicWeight.h, c++/ClSymbolicWeight.cc: Use int, not
 	unsigned, to remove ambiguity in ClSymbolicWeight constructor.

Sat Sep  4 15:17:13 1999   Greg J. Badros  <gjb@cs.washington.edu>

	* acconfig.h: Added NO_CC_PERMISSIVE flag.

	* autogen.sh: Added #!/bin/sh -  to top.

	* configure.in: Test for g++/gcc -fpermissive flag.  Hopefully
	this will let it get used only where it is accepted.  Some better
	guile tests, too.

	* cassowary.spec.in: Use --enable-permissive flag, bump from
	release 3 to 5.

Sat Sep  4 14:44:14 1999   Greg J. Badros  <gjb@cs.washington.edu>

	* c++/Makefile.am, guile/Makefile.am: Added CPPEXTRAFLAGS to
 	AM_CPPFLAGS.

	* guile/Makefile.am: Guard lib_LIBRARIES with HAVE_GUILE test so
	that guile stuff is only built when GUILE is desired and we have
	the libraries installed.

Tue Aug 31 22:16:04 1999   Greg J. Badros  <gjb@cs.washington.edu>

	* java/demos/Makefile.am, java/cda/Makefile.am, java/Makefile.am
 	(install-javaJAVA): Do not try to install .class files if no
 	HAVE_JAVA

Tue Aug 31 21:30:24 1999   Greg J. Badros  <gjb@cs.washington.edu>

	* cassowary.spec.in: Do not use --disable-java-build, since that
	still invokes the rule which is not what I want.

	* java/demos/Makefile.am, java/cda/Makefile.am: Added bogus
 	classjava.stamp rule when no HAVE_JAVA to work around getting an
 	error when trying to run javac with no source files.

	* configure.in: Fix some HAVE_JAVA bugs.  Still not perfect, but better.

Tue Aug 31 17:07:31 1999   Greg J. Badros  <gjb@cs.washington.edu>

	* java/demos/Makefile.am, java/cda/Makefile.am, java/Makefile.am:
 	Added EXTRA_DIST.

Tue Aug 31 16:27:41 1999   Greg J. Badros  <gjb@cs.washington.edu>

	* configure.in (HAVA_JAVA): AC_OUTPUT the java/*/Makefiles.

	* cassowary.spec.in: Use --disable-java-build ./configure option.
	Bump to release 3.

	* Makefile.am: Do not conditionally do directories-- that is
	really broken with automake/rpm building.

Tue Aug 31 16:20:45 1999   Greg J. Badros  <gjb@cs.washington.edu>

	* java/demos/Makefile.am, java/cda/Makefile.am, java/Makefile.am
 	(java_JAVA): Guard with if HAVE_JAVE.

Mon Aug 30 12:03:26 1999   Greg J. Badros  <gjb@cs.washington.edu>

	* cassowary.spec.in: Bump to release 2

	* configure.in: Drop the java/* wrappers/* from AC_OUTPUT macro--
	this breaks java builds but make the Cassowary RPM build more
	cleanly.  I'm going to start making a separate cassowary-java
	distribution unless I can figure out how to make automake and Java 
	co-exist more happily.

Mon Aug 30 12:00:39 1999   Greg J. Badros  <gjb@cs.washington.edu>

	* c++/ClAbstractVariable.h: #include "cl_auto_ptr.h" and use
 	cl_auto_ptr, not auto_ptr.

Mon Aug 30 10:06:50 1999   Greg J. Badros  <gjb@cs.washington.edu>

	* c++/cl_auto_ptr.h: Change the conditional inclusion sandwich to
	CL_AUTO_PTR_H.  Added "#define cl_auto_ptr auto_ptr" for MSVC.

Thu Aug 26 22:42:50 1999   Greg J. Badros  <gjb@cs.washington.edu>

	* cassowary.spec.in: Require guile 1.3.2, to be safe.  Require GTL 
	>= 0.3.1, not gtl >= 0.3.1 (note capitalization)

Thu Aug 26 14:12:42 1999   Greg J. Badros  <gjb@cs.washington.edu>

	* c++/ClFDSolver.h, c++/ClCTest.c, c++/ClC.h, c++/ClC.cc,
 	c++/Cassowary.h, c++/ClConstraint.h: Use LONG_MIN, not MINLONG and
 	#include <limits.h> not <values.h> since the latter is deprecated
 	(and does not work in VC++).

	* THANKS: Thank Pengling He for his VC++ bug report re: values.h
	
Thu Aug 26 14:08:46 1999   Greg J. Badros  <gjb@cs.washington.edu>

	* configure.in (GUILE_PKGDATA_DIR): Set cassoguiledir variable,
	and use ${prefix} prefix of GUILE_PKGDATA_DIR to be sure that rpm
	building succeeds (was failing because it was trying to write to
	an absolute location that guile told it to use, instead of using
	the prefix of $RPM_BUILD_ROOT).

	* c++/Makefile.am: Fix lex/yacc building dependencies.

	* guile/Makefile.am (cassoguile_LTLIBRARIES): Do not set
	cassoguiledir here-- do it in configure.in instead.

Thu Aug 26 11:02:36 1999   Greg J. Badros  <gjb@cs.washington.edu>

	* guile/Makefile.am (EXTRA_DIST), docs/Makefile.am: Added docs to
	EXTRA_DIST.

	* c++/Makefile.am: Added ClReader.l, ClReader.y to EXTRA_DIST,
	remove ClReader.cc from sources.  Added timer.h to
	pkginclude_HEADERS.

	* Makefile.am: Update EXTRA_DIST

Thu Aug 26 08:45:08 1999   Greg J. Badros  <gjb@cs.washington.edu>

	* configure.in: Write cassowary.spec, GTL.spec.  Bump version to
	0.51.

	* autogen.sh: Run configure, not config.status

	* VERSION, README, NEWS, ANNOUNCE: Bump to 0.51, add date, notes.

	* Makefile.am: Drop Java, Python to make easier to package.  Added 
	EXTRA_DIST to include some doc files and the cassowary.spec file.

Wed Aug 25 22:54:18 1999   Greg J. Badros  <gjb@cs.washington.edu>

	* c++/Makefile.am (pkginclude_HEADERS): cl_auto_ptr.h now, not auto_ptr.h

Mon Aug 23 21:26:31 1999   Greg J. Badros  <gjb@cs.washington.edu>

	* ltmain.sh, ltconfig, libtool, configure: Removed -- these are
	autogenerated by autogen.sh

Mon Aug 23 21:23:53 1999   Greg J. Badros  <gjb@cs.washington.edu>

	* c++/ClSimplexSolver.cc: Use cl_auto_ptr, not auto_ptr.

	* c++/ClAbstractVariable.h: #include <memory>, not "auto_ptr.h"

	* c++/cl_auto_ptr.h: Added -- renamed from auto_ptr.h since that
	was causing some difficulties due to the standard C++ auto_ptr template. 

Mon Jul 26 10:19:35 1999  Greg Badros  <gjb@cs.washington.edu>

	* c++/Makefile.am (libcassowary_la_SOURCES): Remove redundant
	listing of ClFD* files from this target.

Mon Jul 26 09:41:09 1999  Greg Badros  <gjb@cs.washington.edu>

	* c++/Cl.h: Include ClConstraint.h, since cnLT, etc., need to be
	defined for ClReader.y

Mon Jul 26 09:22:11 1999  Greg Badros  <gjb@cs.washington.edu>

	* acconfig.h, configure.in: Use CL_ prefix for BUILD_FD_SOLVER and
 	HAVE_GTL.

Mon Jul 26 09:17:56 1999  Greg Badros  <gjb@cs.washington.edu>

	* c++/config.h.in,c++/ClC.h,c++/ClC.cc,c++/Cl.h: Use CL_ prefix on
 	BUILD_FD_SOLVER and HAVE_GTL so that the config-inline.h gets the
 	right definitions.

	* c++/Makefile.am: Expanded out the sources_for_fd_solver since
	the _OBJECTS make variable doesn't get expanded properly if this
	step is deferred until later.  This breaks builds w/o FD solver,
	but I have to get Amaya working ASAP.

Mon Jul 19 17:08:03 1999  Greg Badros  <gjb@cs.washington.edu>

	* c++/ClSymbolicWeight.h: Increase multiplier to 10000 for
	AsDouble-- works around the bug in resizing Scwm windows because
	the medium stay constraints on width and height are too strong for 
	the strong edit constraint.

Sun Jul 11 19:37:39 1999  Greg Badros  <gjb@cs.washington.edu>

	* c++/ClLinearExpression.h: Remove "class" from a typedef

	--with-gtl;  switch --disable-java-build to --enable-java-build

	* acconfig.h, c++/config.h.in: Added HAVE_GTL, BUILD_FD_SOLVER options.

	* c++/Makefile.am: Make only the library and ClTests get built by
	default (other binary test programs are each big when build -g,
	and aren't useful to the end user).  Use @SOURCES_FOR_FD_SOLVER@
	to permit a version of the toolkit to be build without the finite
	domain subsolver.

	* c++/ClC.h, c++/ClC.cc, c++/Cl.h: Add #ifdefs for no fd subsolver.

	* c++/ClReader.l: Permit "_" in identifiers (needed for env
	variable precondition variables).

	* c++/ClLinearInequality.h: Honour _fStrictInequality flag when
	testing FIsSatisfied().

	* c++/ClLinearConstraint.h: Added missing "void" return type for
	ChangeConstant.

Fri Apr 30 09:45:51 1999  Greg J Badros  <gjb@cs.washington.edu>

	* c++/ClFDConnectorVariable.cc, c++/ClFDConnectorVariable.h:

	analogous variable in the Simplex region.

	* Makefile.am: Added ClFDConnectorVariable.[ch] files.

	* c++/ClLinearConstraint.h: Added ChangeConstant()

 	_pfnChangeClvCallback; added default ctr to initialize.  Added
 	SolveNoException(); Moved SetAutosolve(), FIsAutosolving(),
 	SetChangeClvCallback() from ClSimplexSolver up to here.

	* c++/ClSolver.cc: Added PrintTo for list<FDNumber>, operator<<
	for same.

	* c++/ClSimplexSolver.cc: Test constraint with
	FIsOkayForSimplexSolver() before trying to add it (avoids adding
	FD constraints to the simplex solver).
	s/_fOptimizeAutomatically/_fAutosolve/g

	* c++/ClParseTest.cc: Use FCanConvertCn() before trying to.

	* c++/ClFDVariable.h: Make PlfdnDomain() const and return const.

 	c++/ClFDBinaryOneWayConstraint.cc: Make ctr take ClConstraint
 	instead of ClLinearConstraint.  Added EnsurePreconditionsForCn(),

	CL_ClvPrint(). Use CL_Solver for PfnChangeClvCallback, not CL_SimplexSolver.

	* c++/ClAbstractVariable.h: Throw instead of assert(false) in base 
	class IsPivotable(), IsRestricted().

Wed Apr 28 19:38:46 1999  Greg J Badros  <gjb@cs.washington.edu>

Wed Apr 28 18:49:51 1999  Greg J Badros  <gjb@cs.washington.edu>

	* c++/Makefile.am: Added ClCTest to the _PROGRAMS, and use

	require all 3 args to the 3 double ctr to remove ambiguity.

	* c++/ClSimplexSolver.h: Check constraint before adding and throw
	an error if the constraint is no good for the SimplexSolver.

	* c++/ClParseTest.cc: Don't assume a failed add is due to an
	inconsistent system-- could be wrong kind of constraint was read
	in.

	* c++/ClLinearInequality.h: Store the strictness of the
	inequality, since other solvers may be able to use strict ones.

	* c++/ClFDSolver.cc: Fine-tune the exception objects thrown... use 
	the richer hierarchy.

	* c++/ClFDBinaryOneWayConstraint.c,
	c++/ClFDBinaryOneWayConstraint.h:  Added IsStrictInequality(), get 
	the direction of the inequality correct.

Wed Apr 28 12:08:16 1999  Greg J Badros  <gjb@cs.washington.edu>

	* c++/ro-test.in: Added for testing below.

	* c++/ClFDBinaryOneWayConstraint.cc: Added -- so far just a ctr
	from a ClLinearConstraint object (since the parser hands me a
	constraint object that is a ClLinearConstraint object).

Tue Apr 27 20:35:23 1999  Greg J Badros  <gjb@cs.washington.edu>

	* c++/ClSymbolicWeight.h, c++/ClSymbolicWeight.cc: Drop default
 	ctr, and give default arg value to CLevels of 3.  Added operator*.

	* c++/ClFDTests.cc: Better test.

	* c++/ClFDSolver.h, c++/ClFDSolver.cc: Use SymbolicWeights for

	erasing nodes.

Tue Apr 27 10:40:58 1999  Greg J Badros  <gjb@cs.washington.edu>

	* c++/ClSolver.cc: Added -- wrote PrintTo, << basic impls, and
	simple AddConstraint.

	* c++/ClErrors.h: Fixed throw message for ExCLConstraintNotFound
	to not refer to the tableau.

	* c++/ClConstraint.h: Added ClCnRelation (was ClInequalityOperator 
	in c++/ClLinearInequality.h) and wrote StrCnRelation for printing
	it.

	* c++/Cl.h:  include ClFDSolver.h

	* c++/Cassowary.h : include values.h, def FDN_NOTSET (FIXME: drop this?)

Sun Apr 25 18:55:26 1999  Greg J Badros  <gjb@cs.washington.edu>

	* c++/Makefile.am: Added ClFDBinaryOneWayConstraint.h,
	ClFDConstraint.h to pkginclude_HEADERS.

	* c++/ClSimplexSolver.h, c++/ClSimplexSolver.cc: Added optional
 	strength argument to AddPointStays, AddPointStay fns.

	* configure.in: Bump version to .50, for FD features.

Sun Apr 25 11:37:52 1999  Greg J Badros  <gjb@cs.washington.edu>

	* c++/Makefile.am: Comment out the Bug sources/builds, add the FD
	sources.

	* c++/ClSimplexSolver.h: Inherit from ClSolver, too.  Move SetPv, 
	Pv() out into ClSolver base class.

	* c++/ClReadery.y, c++/ClReader.l, c++/ClReader.h: Support "?"
 	read-only annotations, and use Constraint::AddROVars() to track
 	the ro vars of a constraint expression.

	* c++/ClParseTest.cc: Show whether the constraint is added
	successfully or if it is inconsistent.

	* c++/ClLinearConstraint.h: Fix BUG-- super should be
	ClConstraint, not ClLinearConstraint.

	* c++/ClConstraint.h, c++/ClConstraint.cc: Added AddROVars,
 	FIsReadOnlyVar, ReadOnlyVars.

Thu Apr 22 20:18:31 1999  Greg J Badros  <gjb@cs.washington.edu>

	* c++/ClVariable.h: Added ClVariable ctr that takes a
	ClFDVariable*, this ambiguates returning NULL as a ClVariable, so
	may not be a good idea, but it does make it less confusing than
	having another overloaded version of ClVariable's ctr. Added
	IsFloatVariable, IsFDVariable fwding fns.

	* c++/ClSimplexSolver.cc: Disambiguate uses of NULL to be
	(ClFloatVariable *)NULL.

	* c++/ClFloatVariable.h: Added IsFloatVariable() to return true

	* c++/ClC.h, c++/ClC.cc: Added CL_ClvLookupTrim for removing ws
 	around the var name.

	* c++/ClAbstractVariable.h: Make IsPivotable, IsRestricted both
	assert false instead of being pure virtual -- they only need to be 
	overridden if we want to permit them to be called.  Added
	IsFloatVariable(), IsFDVariable() both returning false in this
	base class.

	* c++/Cassowary.h: Added FDNumber typedef to be a long.

	* c++/Makefile.am: Added ClFDVariable.{cc,h}

	* c++/ClFDVariable.cc, c++/ClFDVariable.h: Added, copied from
	ClFloatVariable and modified slightly.

Tue Apr 20 10:18:32 1999  Greg J Badros  <gjb@cs.washington.edu>

	* smalltalk/README: Note that smalltalk implementation is now in
	the public domain.

	* README: Update to version 0.43, note about smalltalk
	implementation being in public domain.

	* LICENSE: Note about not applying to smalltalk implementation

	* ANNOUNCE: Update date to today.

	* *: Changed copyright to be "Greg J. Badros and Alan Borning"
	instead of "Alan Borning and Greg J. Badros".  Okayed by Alan --
	to hopefully encourage more people to write me with their
	questions/problems rather than Alan.

Mon Apr 19 13:45:35 1999  Greg J Badros  <gjb@cs.washington.edu>

	* cassowary.spec: Added --with-guile-prefix

Mon Apr 19 13:02:46 1999  Greg J Badros  <gjb@cs.washington.edu>

	* c++/ClReader.l: Be a bit more careful about end of string
	handling in YY_INPUT-- only return result = 1 if we read a
	non-null character.  Call yy_flush_buffer() before throw-ing an
	error, so that we start anew the next time we are asked to return
	tokens for the parser.

	* c++/ClC.h, c++/ClC.cc: Added CL_SimplexSolverAddStay. (Fix typo
	in .cc)

Fri Apr 16 16:36:24 1999  Greg J Badros  <gjb@cs.washington.edu>

	* c++/ClTests.cc, c++/ClSimplexSolver.h, c++/ClSimplexSolver.cc, : Use "RemoveConstraintNoException", not
	"removeConstraintNoException" (fix initial caps.)

	* c++/ClReader.y: Start looking for a constraint, turn on verbose
	warnings and DEBUG option (still need to set cldebug = 1 in
	debugger)

	* c++/ClReader.h: In operator() for the lookup proc, Return
 	&clvNil() if _pmapVars is still NULL

	* c++/ClC.h, c++/ClC.cc: Added CL_VariableName(..), CL_VarMapDelete(..),
	CL_RemoveConstraint(..) 


Wed Apr 14 16:56:05 1999  Greg J Badros  <gjb@cs.washington.edu>

	* configure.in: Bump to .43.

	* c++/ClC.cc (CL_VarMapDelete, CL_VariableName): Added new functions.

	* cassowary.spec: Added, for building rpms

Wed Mar 31 17:23:18 1999  Greg J Badros  <gjb@cs.washington.edu>

	* wrappers/Makefile.in: Rename PYTHON_HEADERS to PYTHON_HEADER_DIR 
	so it does not get treated specially by automake (?).

	* configure.in: Bump to .42. Added --disable-cpp-build,
	--disable-java-build, and disable Python/Guile builds
	automatically if directories cannot be found.  Drop the
	cassowary from c++/cassowary/config.h -- just use c++/config.h

	* autogen.sh: do not fail if config.status is not -x.

	* Makefile.am: Honour the HAVE_foo flags so that not all subdirs
	have to be built.

Mon Mar 29 21:01:21 1999  Greg J Badros  <gjb@cs.washington.edu>

	* ltconfig, ltmain.sh: Added -- so libtool isn't broken in
	distributions. 

Mon Mar 29 20:59:17 1999  Greg J Badros  <gjb@cs.washington.edu>

	* configure.in: Try to undo a bash-ism.  Untested on a vendor sh,
	but still works with bash.

Sat Mar 20 19:19:37 1999  Greg J Badros  <gjb@cs.washington.edu>

	* Release v0.41.

Sat Mar 20 19:19:13 1999  Greg J Badros  <gjb@cs.washington.edu>

	* Added config.sub and config.guess to the repo -- they were
	symlinks before which broke the distribution.

Thu Mar 18 15:20:51 1999  Greg J Badros  <gjb@cs.washington.edu>

	* Release v0.4.

Thu Mar 18 14:44:39 1999  Greg J Badros  <gjb@cs.washington.edu>

	* configure.in: Do not let config-inline.h get overwritten if it
	is unchanged.  Add some extra messages to tell status of
	config-inline.h

Thu Mar 18 12:59:02 1999  Greg J Badros  <gjb@cs.washington.edu>

	* README, configure.in, wrappers/Makefile.in: Added
 	--with-python-headers configure option.

Thu Mar 18 12:48:55 1999  Greg J Badros  <gjb@cs.washington.edu>

	* README: Added notes about what to do when a subdir build fails,
	suggest -k by default.

	* guile/Makefile.am (test): Added this target for easier way to
	run cltests.scm.

	* guile/README: Updated with notes about how to run cltests.scm. 

	* java/Makefile.in: Fix tests build rule.

Thu Mar 18 11:42:49 1999  Greg J Badros  <gjb@cs.washington.edu>

	* configure.in: Create config-inline.h at end of script.

	* c++/Makefile.am: Do not have rule for building config-inline.h; 
	let configure script do that.

Thu Mar 18 11:05:27 1999  Greg J Badros  <gjb@cs.washington.edu>

	* c++/*.h: Use #include config-inline.h incantation so that header 
	files don't include config.h (since they may be included by
	another package that has its own config.h)

	* c++/*.cc: Use #include config.h as these are build-time-only
	used and can thus rely on the full configure details.

Thu Mar 18 10:57:08 1999  Greg J Badros  <gjb@cs.washington.edu>

	* guile/cassowary_scm.hpp: Use #include config-inline.h
	incantation.

	* guile/cassowary_scm.h: Drop including config.h; it's not
	needed. 

	* guile/cassowary_scm.cc: Use cassowary/config.h, not config.h

Thu Mar 18 10:29:40 1999  Greg J Badros  <gjb@cs.washington.edu>

	* c++/Makefile.am: Install config-inline.h, not config.h, and
	build config-inline.h by grepping for #define CL_ in config.h.
	This works around the problem caused by Scwm including Cassowary
	header files which then included cassowary's config.h and
	conflicted with Scwm's config.h.

Thu Mar 18 10:11:40 1999  Greg J Badros  <gjb@cs.washington.edu>

	* c++/test-*.cc: Only #include "Cl.h"

Thu Mar 18 09:50:45 1999  Greg J Badros  <gjb@cs.washington.edu>

	* wrappers/Makefile.in (clean): use rm -f so we don't get a
	warning if file is missing.

Thu Mar 18 09:49:35 1999  Greg J Badros  <gjb@cs.washington.edu>

	* java/Makefile.in: Use JAVA_CLASS_PATH configure variable.  Fix
	install target to echo a message about the install happening
	during the build.

Wed Mar 17 18:54:16 1999  Greg J Badros  <gjb@cs.washington.edu>

	* c++/Makefile.am: Use libtool, and added lib_LTLIBRARIES.  Put
	benchmarks, bugs, and test programs all under $libdir/cassowary.
	Drop cassoincludedir, as that's just pkginclude, and use
	include_HEADERS for Cl.h and ClC.h, the main top-level includes.
	Also install config.h.

	* c++/Cassowary.h:  #undef PACKAGE, VERSION before #including
	cassowary/config.h as a cheezy workaround. (Switched from "" to
	<>, and ../ to cassowary/ also).

Wed Mar 17 18:50:49 1999  Greg J Badros  <gjb@cs.washington.edu>

	* configure.in: Put config.h in c++/cassowary so cassowary must do 
	#include <cassowary/config.h> so there is no filename conflict
	with other packages including cassowary header files (e.g.,
	Scwm).  Added AM_PROG_LIBTOOL call.  Set GUILE variables outside
	of the guile-prefix ACE_ARG_PATH macro, and set GUILE_PKGDATA_DIR
	use guile-config to find out where we should install the .so file.

Wed Mar 17 18:43:08 1999  Greg J Badros  <gjb@cs.washington.edu>

	* guile/Makefile.am: Updated to build using libtool, and to
	install header files.  Changes name to libconstraints.* so that
	the guile module name (cassowary constraints) works out, and set
	it to install in the right place.

Wed Mar 17 18:39:13 1999  Greg J Badros  <gjb@cs.washington.edu>

	* guile/cltests.scm: Added #! lines, change name of module to
	(cassowary constraints), remove redundant `use-modules' call.

	* guile/cassowary_scm.hpp: #include
	cassowary/ClLinearExpression_fwd.h, not ClLinearExpression_fwd.h

	* guile/cassowary_scm.cc: Change name of module to (cassowary
	constraints).  Make the init_cassowary_scm fn static.

Wed Mar 17 07:39:10 1999  Greg J Badros  <gjb@cs.washington.edu>

	* c++/Cassowary.h, c++/ClSimplexSolver.cc: Switch back to
	including config.h (now ../config.h) from Cassowary.h, instead of
	from ClSimplexSolver.cc.   

Tue Mar 16 19:56:02 1999  Greg J Badros  <gjb@cs.washington.edu>

	* acconfig.h: Fix missing comment closer */

	* c++/Makefile.am: Added AM_CPPFLAGS = $(CPPEXTRAFLAGS)

	* configure.in: Use config.h, not c++/config.h, and permit
	--enable-warnings option to turn on compile-time warnings (uses
	AM_CPPFLAGS in Makefile.am)

Tue Mar 16 19:26:23 1999  Greg J Badros  <gjb@cs.washington.edu>

	* configure.in, acconfig.h: Better autoconf support, including
	several --enable options.  Added acconfig.h to support autoheader
	doing the right thing in making config.h.in.

Tue Mar 16 19:22:50 1999  Greg J Badros  <gjb@cs.washington.edu>

	* c++/ClSimplexSolver.cc, c++/Cassowary.h: Include "config.h" from
 	here, not from Cassowary.h (still not right-- problem is scwm gets 
	the wrong config.h.  Maybe config.h should be in ..?

Tue Mar 16 19:21:06 1999  Greg J Badros  <gjb@cs.washington.edu>

	* java/README: Added note about common error when CLASSPATH is wrong.

Tue Mar 16 15:51:15 1999  Greg J Badros  <gjb@cs.washington.edu>

	* c++/Cassowary.h: #include "config.h"

	* c++/ClSimplexSolver.cc: Use VERSION to init szCassowaryVersion.

Tue Mar 16 12:44:33 1999  Greg J Badros  <gjb@cs.washington.edu>

	* c++/**: Updated function names to always start with an uppercase 
	letter (follows C++ conventions, and brings API of Cassowary and 
	QOCA closer together).  Used scripts/convert-ids to do the
	conversion, along with scripts/ids-to-upper as the list of
	conversions to do.

Wed Mar 10 15:28:33 1999  Greg J Badros  <gjb@cs.washington.edu>

	* Release v0.32.

Wed Mar 10 11:36:37 1999  Greg J Badros  <gjb@cs.washington.edu>

	* **/Makefile: Removed, since these are now generated by
	autoconf from Makefile.in (which itself is generated by
	automake from Makefile.am [only for some directories])

	* configure.in: 
	
	* c++/ClBug2.cc: Added to demonstrate a bug that Anthony Beurivé
	reported.

	* c++/ClSimplexSolver.cc: Fix above-mentioned bug by changing the
	coefficient of the added in removeConstraintInternal.

	* c++/Makefile.linux:  Updated for ClBug2

	* c++/demos/DraggableBox.h: Do not return references to
	ClVariable-s -- just return by value since they are a handle
	class.

	* guile/Makefile.am: changed name of library to
 	libcassowaryguile.a from libconstraints.a

	* java/CL.h: Added a String description argument to assert() to
	permit easier tracking of failures.

	* java/ClSimplexSolver.java: Fix bug that Emmanuel Pietriga
	reported -- use peek() to get at top element of _stkCedns stack
	when removing edit variables in removeEditVarsTo().  Added
	descriptions to assert()s and to throwing of ExCLInternalError.
	Have the addBounds, addUpperBound, addLowerBound functions
	propagate out ExCLInternalError-s instead of catching them and
	printing an error message.  Added messages to all assertions.

	* java/ClLinearExpression.java: Added description to throwing of
	ExCLInternalError.

	* java/ClLinearInequality.java: Added description to throwing of
	ExCLInternalError.

	* java/ExCLInternalError.java: Require description of the error in 
	constructor.

	* java/QuadDemo.java: Use System.err when printing errors, and
	print the description of the exception.

	* smalltalk/ClKernel.app: Fix bug with not using the weight of a
	constraint as the negating coefficient when removing a constraint.

Mon Mar  8 16:40:17 1999  Greg J Badros  <gjb@cs.washington.edu>

	* Added autoconf and partial automake support.  Added numerous
	Makefile.am's, renamed old Makefiles to Makefile.linux (and copied 
	to Makefile.in when I did not write a Makefile.am).  Added
	configure.in.

	* guile/cassowary_scm.cc: Use ClReader.h, not creader.h (I renamed 
	the file)

Fri Mar  5 16:24:05 1999  Greg J Badros  <gjb@cs.washington.edu>

	* c++/Makefile, c++/Cl.h: Fix for renaming of creader.* ->
 	ClReader.*; make C libraries as part of lib, shared_lib rules.

	* c++/ClReader.*: Added, renamed from creader.h, creader.y,
	creader.l

	* c++/ClTableau.h, c++/ClTableau.cc: Added
	printExternalVariablesTo() fn.

	* c++/ClSimplexSolver.cc:  printExternalVariablesTo in
	printInternalInfo.

	CL_TableauPrintExternalVariables()

	* c++/ClC.h, ClC.cc: Added CL_Tableau,
	CL_TableauPrintExternalVariables.  Use "ends" to terminate
	strstreams.  Make Strong Stays use medium strength stays.  Make
	CL_ParseConstraint call ClsFromSz instead of parsing the char *
	itself.

Thu Mar  4 19:08:23 1999  Greg J Badros  <gjb@cs.washington.edu>

	* c++/ClVariable.h: Add assert(pclv) before dereferencing through
	ClVariable's pclv member.

	* c++/Makefile: Added DYNLINK = yes/no variable for controlling
	dynamic linking more easily.

	* c++/ClSimplexSolver.h: Changed PfnChangeClvCallback to take a
	ClVariable * instead of a ClVariable.  This make it easier for the 
	C interface since it has "CLV" as a "ClVariable *" and cannot
	reason about ClVariable-s because it doesn't see the struct defn.

	* c++/ClC.cc, c++/ClC.h:  Added CL_SimplexSolverSetEditedValue,
	CL_SimplexSolverPrint, CL_SimplexSolverSetChangeClvCallback,
	CL_VariableSetPv, CL_VariablePv.

	* c++/ClCTest.cc: Test CL_SimplexSolverSetEditedValue, CL_SimplexSolverPrint.

	* c++/ClVariable.h: Added explict copy ctr.

	* c++/ClEditConstraint.h, c++/ClStayConstraint.h: Changed output
 	format so parentheses started by super:: call to ClConstraint.h
 	are closed properly.

 	pass by reference of ClVariable when used as an output argument.
  	Added printing for ClEditInfo class instancesm,
 	ClVarToEditInfoMap.

Mon Mar  1 13:46:48 1999  Greg J Badros  <gjb@cs.washington.edu>

	* README: Updated for version 0.31.

	* c++/Makefile: Added QocaBench.o to TEST_OBJS, comment out
	CL_USE_HASH_MAP_AND_SET by default.

	* c++/ClTestColumns.cc: Allocate constraint objects on heap, not

	c++/ClEditOrStayConstraint.h, c++/ClEditConstraint.h: Pass and
	return ClVariable-s by value, not by reference. (Fixes bug in
	QocaBench from re-use of a ClVariable object with the underlying
	pointer different.

	* c++/README:  Fix spelling of deprecated, URL for WxWindows.

	* c++/test-ClConstraint.cc: Comment out unused variables

Mon Mar  1 12:53:02 1999  Greg J Badros  <gjb@cs.washington.edu>

	* c++/qdemos/QuadDemoWindow.cc:  Allocate constraint objects on
	heap, not as temporaries on local stack.

Fri Feb 26 09:16:31 1999  Greg J Badros  <gjb@cs.washington.edu>

	* wrappers/cassowary.i: Use .c_str() off of exception descriptions 
	to get the char * (description() now returns a string)

Fri Feb 26 09:11:17 1999  Greg J Badros  <gjb@cs.washington.edu>

	* c++/ClConstraint.h: Added FIsInSolver()

	* guile/cassowary_scm.cc: Wrap cl-constraint-is-in-solver?

Thu Feb 25 18:58:55 1999  Greg J Badros  <gjb@cs.washington.edu>

	* guile/cltests.scm: Added (use-modules..) invocation to get the
	dynamically-loaded module so that it can be tested outside of
	scwm.  Updated to reflect changed behaviour in cl-add-stay.  Added 
	some test code for make-cl-constraint-from-string.

	* guile/cassowary_scm.hpp:  Added ScmMakeClConstraint(..) to
	abstract out setting "answer" for the (now) two ClConstraint ctrs.

	* guile/cassowary_scm.cc: Added make-cl-constraint-from-string for
 	interfacing to the parser.  Wrap
	cl-constraint-change-{strength,weight}!. Make dynamically loadable 
	module! Fix BUG: was returning SCM_UNDEFINED instead of
	SCM_UNSPECIFIED.

	* guile/Makefile: Build libconstraints.so, and necessary directory 
	structure if neeeded.


Thu Feb 25 18:41:34 1999  Greg J Badros  <gjb@cs.washington.edu>

	* c++/ClSimplexSolver.h, c++/ClSimplexSolver.cc:  Make constraints 
	get told when they're added/removed from a solver.  This means
	that constraints are no longer const params to add/remove
	Constraint functions, and also that removeConstraint needs an
	internal version that doesn't do the counting (since
	removeConstraint can get called from addConstraint to clean up
	after a failed addition).

	* c++/ClSimplexSolver.cc: Clean up uses of ClConstraint &cn --
	prefer ClConstraint *pcn even internally.

	* c++/ClConstraint.h: Added ChangeStrength(..), ChangeWeight(..)
	and _times_added memvar along w/ private (for friend
	ClSimplexSolver) addedTo(..) and removedFrom(..) functions.  Only
	permit strength/weight changing if constraint is in no solvers
	presently. 

	* c++/ClConstraint.cc: Output _times_added memvar in printOn(...)

Thu Feb 25 15:58:27 1999  Greg J Badros  <gjb@cs.washington.edu>

	* c++/ClErrors.h: Added parse error classes, and have description
	return a "string" instead of a "char *"

	* c++/creader.y: Use exception ExCLParseErrorMisc in clerror, Use
	ClVarLookupFunction instead of mapVars and fAutoCreate

	* c++/creader.l: Use ClVarLookupFunction instead of doing it
	inline with mapVars and fAutoCreate;  throw exceptions on errors.

	* c++/creader.h: Added ClVarLookupFunction and ClVarLookupInMap
	and use them when parsing.

	* c++/Makefile:  Added some dependencies for proper building of
	.l,.y files

	* c++/ClSimplexSolver.cc: Descend VarInVarSet from
	unary_function<..,..>

	* c++/ClParseTest.cc: Catch parse errors and display the message.
	Use ClVarLookupInMap class

	* c++/ClSimplexSolver.cc: Simplify removeConstraint to not use
	references. 

	* c++/ClSimplexSolver.h: Updated a comment

	* c++/ClTests.cc: Use addEditVar, beginEdit, and endEdit, instead
	of building EditConstraints directly.

Tue Feb 23 18:48:21 1999  Greg J Badros  <gjb@cs.washington.edu>

	* c++/creader.y, c++/creader.h: Remove old crummy lexer.  Added
 	fAutoCreate flag to PcnParseConstraint to allow parsing with
 	automatic introduction of newly-referenced variables.

	* c++/creader.l: Fixed bugs in missing tokens "|", "(", ")", and
	permit "==" as a synonym for "=".  Honour the _fAutoCreate flag by 
	introducing variables when needed.

	* c++/ClTests.cc: Display version id string at startup.

	* c++/ClSimplexSolver.cc, c++/Cl.h: Added szCassowaryVersion id
	string.

	* c++/ClParseTest.cc: Test auto-addition of variable (fAutoCreate
	= true)

Tue Feb 23 18:12:23 1999  Greg J Badros  <gjb@cs.washington.edu>

	* c++/Makefile: Build libcassowary.{a,so} by default, not
	libcassowary-notrace.{a,so}.  Remove special rule for building
	ClParseTest; list creader-lex.o, creader.o in OBJS and have them
	be a part of the library.

	* c++/ClVariable.h, c++/ClVariable.cc: Rename pmapSzPclv to
	pmapStrPclv.  Make it a map from "const string" not "string".
	Make setName erase the old mapping, and add the new mapping.

	* c++/ClParseTest.cc: Accept "-" option to mean "rename x to foo"
	for testing the setName change above.

	* c++/ClFloatVariable.cc: Do not output warning msg in setName --
	instead, do the right thing in ClVariable.h

Tue Feb 23 08:55:28 1999  Greg J Badros  <gjb@cs.washington.edu>

	* c++/Makefile: Fix build rules for bison/flex parser so
	dependencies are correct.  Added new targets, all-notests,
	all-tests, make 'lib' the default target, and all really build
	everything.

	* c++/creader.h, c++/creader.l, c++/creader.y: Take address of
	ClVariable-s from the map's values (cannot use ClVariable in the
	union directly because union members cannot have constructors).
	#include ClVariable.h instead of fwd decl of ClVariable so that we 
	get the StringToVarMap typedef, too.

Mon Feb 22 16:33:16 1999  Greg J Badros  <gjb@cs.washington.edu>

	* c++/Makefile: Use CL_LIBRARY, not LIB_FILE, throughout. Use
	flags for maximum performance.

	* c++/ClVariable.h, c++/ClConstraintHash.h, c++/Cassowary.h:
 	Divide pointer address by CL_PTR_HASH_DIVISOR in hash functions

	* c++/ClTests.cc:  Added CL_SHOW_CNS_IN_BENCHMARK guard protecting 
	new displaying of constraints and listing of inconsistent constraints.

Mon Feb 22 12:18:53 1999  Greg J Badros  <gjb@cs.washington.edu>

	* c++/ClTests.cc (inconsistent3): Drop extra redundant
	inconsistency for pedagogical reasons.  Use simpler pointer-based
	addConstraint in benchmark test

	* c++/ClSimplexSolver.h: Added addConstraintNoException,
	removeConstraintNoException taking ClConstraint &'s -- deprecated.
	Added CL_NO_DEPRECATED guard for turning off availability of
	deprecated functions.

Mon Feb 22 11:12:35 1999  Greg J Badros  <gjb@cs.washington.edu>

	* c++/ClSimplexSolver.h: Added deprecated
	FIsConstraintSatisfied(Constraint &)

	* guile/cassowary_scm.cc: Use ClConstraintToVarMap for return
	value of ConstraintMap().  Pass Constraint *'s instead of &'s.
	Use new name printOnVerbose instead of printDebugInfo.

Fri Feb 19  Greg J Badros  <gjb@cs.washington.edu>

	* Release v0.3.

Fri Feb 19 18:00:49 1999  Greg J Badros  <gjb@cs.washington.edu>

	* c++/ClTests.cc: Updated to fix below interface.

	* c++/ClSimplexSolver.cc, c++/ClSimplexSolver.h: make
 	addConstraint, addConstraintNoException, removeConstraint,
 	removeConstraintNoException take ClConstraint *'s instead of
 	ClConstraint &'s.  Clarifies the mental model, and simplifies the
 	syntax.  Old style is still accepted, but is deprecated.

Fri Feb 19 17:41:45 1999  Greg J Badros  <gjb@cs.washington.edu>

	* c++/ClFloatVariable.cc, c++/ClFloatVariable.h: Added -- moved
	here from ClVariable.h, and renamed from class ClVariableRep since 
	they not what ClVariable wraps (ClVariable wraps
	ClAbstractVariable)

	* c++/ClAbstractVariable.h: Fatten interface to include set_value, 
	change_value, setPv, and Pv.

	* c++/ClVariable.h, c++/ClVariable.cc: Move ClVariableRep into
	ClFloatVariable.{h,cc}, and use pclv-> for
	set_value, change_value, SetPv, and Pv since ClAbstractVariable
	now has a fat interface and we do not need to do the dynamic
	down-casting. 

	* c++/Makefile: Added new files to build rules.

Fri Feb 19 17:08:29 1999  Greg J Badros  <gjb@cs.washington.edu>

	* c++/debug.h, c++/ClTableau.h: Move operator<< out into ClTableau.h

	* c++/ClVariable.h, c++/ClVariable.cc: Move some inline functions
	into .cc so that the hash function can go in the .h file (some stl 
	dependency issue, it seems).

	* c++/ClErrors.h, c++/ClTypedefs.h: Move typedef for
 	ClConstraintSet from ClErrors.h into ClTypedefs.h, and have former 
	include the latter.

	* c++/Cassowary.h: #include ClConstraintHash.h

	* c++/ClConstraintHash.h: Added.  The hash function needs to
	appear before any typedef that uses a hash_map or hash_set, so
	this file is included by Cassowary.h

Fri Feb 19 08:45:24 1999  Greg J Badros  <gjb@cs.washington.edu>

	* c++/ClSubgraphTest.cc: Fix some bugs just from not testing
	completely. 

	* c++/*: Fix bugs from not-updated-code hidden by #ifdefs.  Builds 
	w/ all compile-options except -DCL_USE_HASH_MAP_AND_SET.  Drop
	some gratuitous appearances of ClAbstractVariable

Thu Feb 18 18:53:56 1999  Greg J Badros  <gjb@cs.washington.edu>

	* c++/ClLinearExpression.cc: Use clvNill when returning a
	ClVariable instead of NULL

	* c++/ClVariable.h, c++/ClVariable.cc: operators ==, !=, < all should use the
	contained pointers address, not value.  Also define global clvNil,
	isNil(). 

	* c++/ClTests.cc: BUGFIX: #if 0 removed from adding stays in
	simple1 test

	* c++/ClSimplexSolver.h:  Use ClVariable-s internally for
	ClObjectiveVariable-s.

	* c++/ClSimplexSolver.cc: Use ClVariable-s internally for
	ClObjectiveVariable-s and replace ClAbstractVariable
	*p{entryVar,exitVar} with ClVariable-s.  (Use clvNil and isNil()
	to test for not yet set).

Thu Feb 18  Greg J Badros  <gjb@cs.washington.edu>
	
	* c++/*: First compilable and almost working version with
 	ClVariable as a handle to ClVariableRep.  Major simplifications
	throughout.

Thu Feb 18 14:22:14 1999  Greg J Badros  <gjb@cs.washington.edu>

	* c++/Makefile: Split out the options into += lists so they can be 
	flipped independently more easily.
	
	* c++/ClSimplexSolver.cc, c++/ClSimplexSolver.h: Added output
	operation for ClConstraintToVarSetMap;  use fFoundErrorVar flag to 
	simplify some redundant tests in removeConstraint -- no longer use 
	errorVarsCopy.

	* c++/CLVariable.h: Fix a comment's example.

	* c++/ClTypedefs.h: Use set always for ClTableauVarSet (Steve
	Wolfman notes that it's faster as a set than as a hash_set).

	* c++/debug.h: Add CtrTracer, DtrTracer fns that do nothing when
	not CL_TRACE

	* c++/ClConstraint.h:  Invoke CtrTracer, DtrTracer in ctr, dtr for 
	finding memory problem

	* c++/ClTests.cc: Fix some long-time bugs in the use of ctrs that
	build temporary objects whose lifetime was expected to be longer
	than it was.

	* c++/*: Invert sense of CL_NO_TRACE to CL_TRACE

Wed Feb 17 12:10:28 1999  Greg J Badros  <gjb@cs.washington.edu>

	* c++/ClTypedefs.h: Added -- factored out useful typedefs from
	ClSimplexSolver.h, ClTableau.h and put them in this file.

	* c++/ClTableau.h, c++/ClSimplexSolver.h, c++/debug.h:  Use
	ClTypedefs.h.  Drop gdb_print (it uses printOn and printTo, now).
	Renamed printDebugInfo to printOnVerbose (for generalized gdb
	interface)

	* c++/ClSimplexSolver.cc: Fix two bugs where I was modifying data
	structures indirectly while iterating over them.  Remove a delete
	that was premature to fix another bug in optimized builds.

	* c++/ClLinearExpression.h, c++/ClConstraint.h,
 	c++/ClAbstractVariable.h: Drop gdb_print().

	* c++/ClSymbolicWeight.h: Use Number instead of double more consistently.

Tue Feb 16 15:04:06 1999  Greg J Badros  <gjb@cs.washington.edu>

	* c++/Cassowary.h,ClAbstractVariable.h,ClMap.h,ClSet.h,Makefile: Use

	maintaining symbol table of ClVariables.  Added
	setAttachedObject(..), getAttachedObject() for hanging something
	off of a variable.

	* java/ClConstraint.java: Added setAttachedObject(..),
 	getAttachedObject() for hanging something off of a constraint.

	* java/ClTests.java:  Added inconsistent3() and multiedit() tests

	* java/ClSimplexSolver.java: Manage multiple (nested) edits
	properly.  Provide access to the _markerVars var through
	getConstraintMap() accessor.  Deprecate resolve(Vector) fn.

Tue Feb 16 14:29:46 1999  Greg J Badros  <gjb@cs.washington.edu>

	* README: Updated reference to swig web site.

Tue Feb 16 12:45:04 1999  Greg J Badros  <gjb@cs.washington.edu>

	* java/ClSimplexSolver.java, java/ClEditInfo.java, java/Makefile: 
	Fixed Michael Kaufmann's bug.  (See Feb 15 note for C++ version
	two entries below.)

Tue Feb 16 10:51:01 1999  Greg J Badros  <gjb@cs.washington.edu>

	* c++/*: Added CL_FIND_LEAK guard and ctr/ctr counters for
	tracking various variable kinds.

Mon Feb 15 18:38:06 1999  Greg J Badros  <gjb@cs.washington.edu>

	* c++/ClAbstractVariable.{cc,h}, ClSlackVariable.{cc,h},
	ClDummyVariable.{cc,h}: Add counters to ctr/dtr for leakage detection.

	* c++/ClSimplexSolver.{cc,h}: Replace ClConstraintAndIndex with
	ClEditInfo, and remove ugliness of parallel vectors for edit
	constraints. Drop _editPlusErrorVars, _editMinusErrorVars,
	_prevEditConstants, and bundle them all up in the value end of the 
	map attached to _editVarMap.  This fixes a bug reported in the
	Java version by Michael Kaufmann long ago, and generally cleans
	code up a bit.  The resolve(vector<Number>) function is
	deprecated, and now implemented in terms of the indices stored in
	the new ClEditInfo class.

	* c++/*: Updated copyright to include 1999.

1999-02-15  Greg J Badros  <gjb@cs.washington.edu>

	* c++/ClVariable.{cc,h}, c++/ClAbstractVariable.h: Added
	SetVarMap(..), VarMap(), and make variables given names get their
	names mapped to the objects in the var map (for access when
	parsing constraints as strings).  Make setName() virtual so
	ClVariable can override it.

1999-02-12  Greg J Badros  <gjb@cs.washington.edu>

	* c++/creader.{y,h}: New version from Steve Wolfman, slightly
	updated for cleaner integration. Pass in a map<string,ClVariable
	*> instead of an array of ClVariable; improve error handling a
	bit.

	* c++/debug.h: Use ClMap, ClSet

	* c++/{ClMap.h,ClSet.h}: Added, for optionally using hash_map,
	hash_set instead of map, set.

	* c++/ClSimplexSolver.{cc,h}: Added Steve Wolfman's explanation
	support (added back map for marker->constraint, _fExplainFailure
	var + getter & settor).  Use ClMap, ClSet.  Cleaned up some cerr
	output, and use DEBUG_FAILURES cpp symbol to guard some output.

	* c++/Cassowary.h: Added operator() for hash<..> to support
	hashing things used as keys in hash_map/hash_set

	* c++/ClErrors.h: Added ExCLRequiredFailureWithExplanation class
	for explanation support.

	* c++/{ClLinearExpression.h,ClTableau.h}: Use ClMap, not map. Use
	ClSet, not set.

	* c++/ClSymbolicWeight.h: Return a symbolic weight even when
	assert(false) to avoid compiler warning.

1999-02-11  Greg J Badros  <gjb@cs.washington.edu>

	* guile/cassowary_scm.cc: Use cl-snarf.h, not scwm-snarf.h.  Use
	CL_PROC to denote primitives, not SCWM_PROC.  Use
	CL_VAR_INIT_PERMANENT macro for variables, and document them (the
	strength objects only, for now).  Fix the default strength of
	cl-add-editvar to Strong, not Weak, and update docs (was cut&paste
	error from the cl-add-stay primitive).  Thanks Anthony Beurivé for
	noticing this bug, too!

Sat Jan 30  Greg Badros  <gjb@cs.washington.edu>

	* Release v0.23.
	
Sat Jan 30 13:16:31 1999  Greg Badros  <gjb@cs.washington.edu>

	* c++/ClSimplexSolver.cc: Fixed bug in removing a stay
	constraint.  Was editing a vector in place while iterating over
	it.  Now I use remove_if and erase.  Thanks to Anthony Beurivé for 
	noticing the bug.

	* c++/ClBug1.cc: Added -- bug report from Anthony Beurivé.

Sat Jan 23 Greg Badros  <gjb@cs.washington.edu>

	* Release v0.22.
	
Sat Jan 23 16:46:27 1999  Greg Badros  <gjb@cs.washington.edu>

	* guile/cassowary_scm.cc: Replace iarg uses with literal argument
	index numbers.  Use const_cast to avoid warnings when calling
	ScmMakeClStrength on clsWeak,clsMedium,clsStrong,clsRequired objects

Sat Jan 23 15:30:16 1999  Greg Badros  <gjb@cs.washington.edu>

	* c++/ClSimplexSolver.cc: Added some comments, some explanations
	when exceptions are thrown, and some minor cleanups, bug-fixes

	* c++/ClTests.cc: Added inconsistent3() test, and run it.

	* c++/ClStrength.h: Added _pv memvar, and setPv(), Pv() -- needed
	for tracking ClStrengths in guile

	* guile/cassowary_scm.cc: Replace all iarg uses with the literal
	number.  Point ClStrength objects at their scheme-level object
	using their new _pv field.  Protect ClStrength objects properly.

Sat Sep 19 17:08:21 1998  Greg Badros  <gjb@cs.washington.edu>

	* c++/Makefile (CPPFLAGS): Added USE_GC, commented out, and added
	OTHER_LIBS variable for linking with the gc library

Sat Sep 19 17:01:16 1998  Greg Badros  <gjb@cs.washington.edu>

	* c++/ClTableau.h: Added AssertValid() for testing integrity of
	Tableau

	* c++/ClSymbolicWeight.h, c++/ClStrength.h, c++/ClSlackVariable.h,
	c++/ClLinearExpression.h, c++/ClErrors.h, c++/ClDummyVariable.h,
	c++/ClConstraint.h, c++/ClAbstractVariable.h:  Descend objects
	from "gc" class conditioned on USE_GC* pp macros

	* c++/Cassowary.h: Conditionally include gc_cpp.h ifdef USE_GC;
	added NEWVAR and DELVAR macros for outputting debug information at 
	new/delete sites

	* c++/ClSimplexSolver.h: Call AssertValid before solving

	* c++/ClSimplexSolver.cc: Remove memory leak of the artificial
	objective variable

	* c++/ClLinearExpression.h: Fix gdb_print to have a newline

	* c++/ClLeakTest: Added leakTest2 which more obviously leaks, and
	use GC_gcollect() to force a collect

Tue Sep 15 16:36:20 1998  Greg Badros  <gjb@cs.washington.edu>

	* c++/ClTableau.h, ClTableau.cc: Handle removing vars from _columns more
	carefully, and add gdb_print(), virtual destructor

	* c++/ClLinearExpression.h, c++/ClConstraint.h,
 	c++/ClAbstractVariable.h: Added gdb_print()

Tue Sep 14  Greg Badros  <gjb@cs.washington.edu>

	* Release v0.21.

Wed Sep  9 09:46:35 1998  Greg Badros  <gjb@cs.washington.edu>

	* c++/ClLinearExpression.h, c++/ClLinearExpression.cc: added uses
	of 'typename' keyword as needed by egcs-1.1b's -pedantic (and the
	C++ FDIS)

Sun Sep  6 13:19:01 1998  Greg Badros  <gjb@cs.washington.edu>

	* c++/ClSimplexSolver.h: Added _pv field, and Pv() setPv() getter
	and setter
	
	* guile/cassowary_scm.cc: Use solver's _pv field to point
	ClSimplexSolver back at the scheme object that wraps it

Fri Sep  4 18:52:50 1998  Greg Badros  <gjb@cs.washington.edu>

	* guile/cassowary_scm.hpp, guile/cassowary_scm.cc: Added PvFromScm 
	and ScmFromPv to hide the reinterpret casts used to store a scheme 
	object as the void * Pv() attached to a cassowary object.  Attach
	the scheme-level cl-variable to a ClVariable object.  Added
	`clv-attach!' and `clv-attached-object' to manipulate the attached 
	object (often better to use scheme level properties, though)

Fri Sep  4 18:51:30 1998  Greg Badros  <gjb@cs.washington.edu>

	* guile/Makefile: Use "perl" from path to run extract docs instead 
	of relying on #! line, and generate the -procedures.txt file as
	well as the .sgml file

Wed Sep  2 17:08:14 1998  Greg Badros  <gjb@cs.washington.edu>

	* guile/cassowary_scm.cc, guile/cassowary_scm.hpp: Added
	ClStayConstraint wrapper.  Make cl-add-stay, cl-add-editvar take a 
	list of variables instead of a varargs last argument and instead
	add two optional arguments STRENGTH and FACTOR (thus those
	primitives remain backward compatible as long as only one variable 
	was given).

Wed Sep  2 13:55:37 1998  Greg Badros  <gjb@cs.washington.edu>

	* ClSimplexSolver.h: Added weight option to addEditVar and use it

	* ClLinearExpression.h: Added PconstClAbstractVariable, use it;
	use ClVarToCoeffMap in coefficientFor.

Thu Aug  6 20:56:45 1998  Greg Badros  <gjb@cs.washington.edu>

	* Release v0.2.

Thu Aug  6 20:41:40 1998  Greg Badros  <gjb@cs.washington.edu>

	* ClTests.cc: Added multiedit() test for testing nested
	  beginEdit-s

	* ClSimplexSolver.h, ClSimplexSolver.cc: Support nested
	  beginEdit-s -- use removeEditVarsTo(n), and rewrite
	  removeAllEditVars in terms of the former;  Use FIsSatisfied on
	  constraint and compare with testing internally for
	  FIsConstraintSatisfied() -- untested.

	* ClLinearInequality.h, ClLinearEquation.h, ClConstraint.h: Added
	  virtual FIsSatisfied

	* ClLinearExpression.h, ClLinearExpression.cc: Added evaluate()

	* ClAbstractVariable.h: Return 0 for value(), and make it a
	  virtual function.

Wed Aug  5 16:10:56 1998  Greg Badros  <gjb@cs.washington.edu>

	* ClStrength.h: Have ClStrength::symbolicWeight return a const
	  ref, instead of by value, make clsXXX const refs.

	* ClSimplexSolver.cc, ClLinearInequality.cc, ClLinearEquation.cc,
	  ClLinearConstraint.cc: Take ClStrengths by const refs

Tue Aug  4 15:22:08 1998  Greg Badros  <gjb@cs.washington.edu>

	* guile/cassowary_scm.cc, cassowary_scm.hpp: Move all inline
	  functions into .hpp file.  Added cl-is-constraint-satisfied?
	
	* ClTableau.h: Added a rowExpression() const memfn, for
	  FIsConstraintSatisfied()

	* ClSimplexSolver.h, ClSimplexSolver.cc: Added (probably broken)
	  FIsConstraintSatisfied(cn) memfn -- needs testing

Sun Aug  2 16:49:34 1998  Greg Badros  <gjb@cs.washington.edu>

	* ClSimplexSolver.h: Added ConstraintMap() accessor to
	_markerVars, for cl-constraint-list guile primitive

	* ClConstraint.h: Added setPv(), Pv(), and _pv field to a
	constraint, for attaching extra information.

Thu Jul 30 19:15:40 1998  Greg Badros  <gjb@cs.washington.edu>

	* ClTests.cc: Added simple2, to test new EditMisuse exception on
	editing a variable that is nowhere in the solver.

	* ClTableau.h, ClTableau.cc:  Be more careful about inserting into
	_externalParametricVars; add FIsBasicVar to assist that care.

	* ClSimplexSolver.cc, ClSimplexSolver.h: Added pfnCnSatCallback -- 
	does nothing for now;  throw an ExCLEditMisuse exception if an
	edit constraint is added on a variable that is not in the tableau
	(needs at least a stay constraint in the solver); replace some
	calls to rowExpression with FIsBasicVar when the latter is the
	intent.

Thu Jul 21  Greg Badros  <gjb@cs.washington.edu>

	* ClVariable.h, ClVariable.cc: Added _pv field, settor and gettor.

	
ABOVE CHANGES ONLY IN C++ IMPLEMENTATION AND ITS WRAPPERS
	
Fri Jul 17 19:24:54 1998  Greg Badros  <gjb@cs.washington.edu>

	* ClVariable.h, .java: Added change_value memfn, and make it virtual
 	instead of setValue -- thus subclasses can specialize behaviour
 	when the variable gets set by the solver.

	* ClSimplexSolver.h, .java: Use change_value for setEditedValue if
	the variable is not in the tableau;  call resolve() before
	removeAllEditVars in endEdit

	* ClSimplexSolver.cc, .java (setExternalVariables): Use change_value
	instead of set_value when so subclasses can override and notice a
	changed variable

Thu Jul 16 19:49:45 1998  Greg Badros  <gjb@cs.washington.edu>

	* Added setEditedValue(), FContainsVariable(), and addVar() to c++ 
	and Java implementations

	* Fixed bug in C++ and Java in solvers lacking stay constraints
 	that was due to not-updating the external parametric variables
 	set.

Fri Jul 10 09:00:15 1998  Greg Badros  <gjb@cs.washington.edu>

	* Fixed bug whereby a dummy variable was being pivoted into the
	basis because pexpr->anyVariable() didn't guarantee the variable
	it returned was a pivotable variable -- now it's called
	anyPivotableVariable(), and does the right thing.

	* Fixed bug whereby column mappings that had no rows remained in
	the list of columns -- now erase the column key when its value is
	the empty set

	* Fixed bug whereby constraints that threw required failure
	exceptions remained in the tableau (a removeConstraint on a
	constraint that failed to be added used to succeed, now it does
	not)

Monday Jun 29 16:50:00 1998  Greg Badros  <gjb@cs.washington.edu>

	* Release Cassowary v0.1  --- see local/POST-ANNOUNCE-TO for
	list of places where it was announced
