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].

Badros <gjb@cs.washington.edu> + + * java/ClSimplexSolver.java (addLowerBound, addUpperBound): Fix + these two functions to call addConstraint before returning. + Thanks Stephen Allain for catching this! Updated exception specs + for those methods and for addBounds. + +Tue Dec 7 08:42:34 1999 Greg J. Badros <gjb@cs.washington.edu> + + * 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 + when no --with-gtl option is given.

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. + + * c++/ClLinearInequality.h: Throw an editmisuse when a + ClLinearInequality is created w/o an inequality operator. + +Tue Nov 23 16:54:05 1999 Greg J. Badros <gjb@cs.washington.edu> + + * configure.in: Use guile's pkglibdir, not pkgdatadir, for + choosing cassoguiledir. + +Tue Nov 16 17:35:54 1999 Greg J. Badros <gjb@cs.washington.edu> + + * java/ClReader.lex, java/ClReader.cup: Added -- code by Will + Portnoy for adding a parser to the Java implementation.

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. + + * NEWS: Updated for 0.53 release. + + * Makefile.am: Added smalltalk directory to SUBDIRS. + +Sat Oct 23 14:34:27 1999 Greg J.

Badros <gjb@cs.washington.edu> + + * c++/ClSimplexSolver.cc: Use clvNil some places instead of NULL. + This is important for newer, pickier gcc-2.95.x. Thanks Alexandre + 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 + Harry Hochheiser for bug report. + +Sun Sep 26 13:43:12 1999 Greg J.

Badros <gjb@cs.washington.edu> + + * guile/cassowary_scm.cc: Fix `cl-int-value' to use gh_int2scm + instead of gh_double2scm + +Sun Sep 19 14:45:59 1999 Greg J. Badros <gjb@cs.washington.edu> + + * 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.

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.
