|
|
26-August-1999: Version 0.51 pre-releases begin
|
|
|
|
12-July-1999: Version 0.50 released.
|
|
* Made only C++ version build by default, --enable-java-build is needed to turn java on
|
|
* Added restricted finite domain solver
|
|
** needs --with-gtl configure option, and libGTL.{a,so*} to be installed
|
|
* Added ClSolver base class, and use its type for pointers in callbacks
|
|
|

|
|
automatically if directories cannot be found
|
|
|
|
20-Mar-1999: Version 0.41 released.
|
|
* Fixed bug in autoconf support -- config.sub, config.guess to the
|
|
distribution so configure should actually work (they were symlinks
|
|
before, in error).
|
|
|
|
18-Mar-1999: Version 0.4 released.
|
|
|
|
18-Mar-1999: Changes since Cassowary v0.32 (for release v0.4)
|
|
* MUCH improved autoconf/automake support including numerous configure
|
|
options, added libtool support.
|
|
* Renamed many identifiers in the public API; this will break old code
|
|
using Cassowary. See the scripts/convert-ids script for help converting
|
|
your code (beware false positives; i.e., improper or unnecessary
|
|
changes).
|
|
|
|
|
|
10-Mar-1999: Changes since Cassowary v0.31 (for release v0.32)
|
|
* Added automake/autoconf support. Old Makefiles are now
|
|
Makefile.linux. This is not yet fully tested or correct, but I need to
|
|
make a release now for the bug fixes. Consider compiling with "make -f
|
|
Makefile.linux all" if you have problems running autoconf and/or
|
|
automake.
|
|
|
|
* Changes to C++
|
|
** Bug fix for problem Anthony Beurivé noticed regarding removing non-1
|
|
weight stay constraints.
|
|
** Minor bug fix for parser. Also renamed the creader files to ClReader.
|
|
|
|
* Changes to Java
|
|
** Bug fix for problem Emmanuel Pietriga reported regarding edit
|
|
constraints.
|
|
** Improved debugging support a bit by adding descriptions to
|
|
ExCLInternalError-s and assert()s
|
|
|
|
* Changes to guile wrapper
|
|
** changed name of library to libcassowaryguile.a from libconstraints.a
|
|
|
|
|
|
1-Mar-1999: Changes since Cassowary v0.3 (for release v0.31)
|
|
* Changes to C++
|
|
** Some bug fixes -- pass ClVariable-s around by value instead of const
|
|
& since they are now a handle class.
|
|
** Changed output format for ClEditConstraint, ClStayConstraint instances
|
|
** Use a function-object for controlling lookup/creation of variables in PcnParseConstraint
|
|
** Fix bugs in creader.y parser (did not accept parens or division
|
|
before). Introduced "==" as a a synonym for "="
|
|
** Added szCassowaryVersion id string as a public char *.
|
|
** Added ChangeStrength, ChangeWeight to ClConstraint's public
|
|
interface, and have it valid only when the constraint is not in a solver
|
|
** Added ClConstraint::FIsInSolver()
|
|
|
|
* Changes to Guile wrapper
|
|
** Fix bugs
|
|
** Wrap parsing functionality, including a lambda for lookup/creation of
|
|
variables
|
|
** Build a dynamically-loadable guile module, update cltests.scm to use it
|
|
|
|
|
|
23-Feb-1999: Version 0.3 released.
|
|
|
|
19-Feb-1999, Changes since Cassowary v0.23 (for release v0.3)
|
|
|
|
* Changes to Java and C++
|
|
** Bug fix for Michael Kaufmann's report (see ChangeLog for details)
|
|
** resolve(Vector..) procedure is now depracated; preferred interface is
|
|
suggestValue(...) calls followed by resolve() (the one taking no
|
|
arguments).
|
|
** Added ClVariable::SetVarMap(..), ClVariable::VarMap() to permit
|
|
ClVariable ctr to save the mapping between given name and actual object
|
|
in a symbol table (used for parsing ascii expressions in C++ version)
|
|
|
|
* Changes to just C++ implementation
|
|
** Use ClVariable as a handle class to a ClAbstractVariable-- old
|
|
ClVariable is now a ClFloatVariable. SetChangeClvCallback now takes a
|
|
function that takes a ClVariable handle, not a pointer.
|
|
** Passing ClConstraints's by const & is now deprecated -- pass by
|
|
pointer to the ClConstraint object
|
|
** Added creader.y, creader.l and function PcnParseConstraint(..) for
|
|
creating a constraint from an ASCII string.
|
|
** Added CL_NO_IO compile-time option to C++ version for preventing need
|
|
to link with the stream library (is not complete)
|
|
** Added CL_FIND_LEAK compile-time option for counting ctrs/dtr
|
|
invocations
|
|
** Added CL_USE_HASH_MAP compile-time option to permit using the GNU
|
|
hash_map class instead of the standard STL map (which is a sorted
|
|
associative container whose performance for lookups is logarithmic
|
|
rather than constant time). Still does not work for me --02/16/99 gjb.
|
|
|
|
* Changes to just Java implementation (updated to match changes to C++
|
|
version for .2)
|
|
** Added {get,set}AttachedObject for ClVariable, ClConstant
|
|
** Permit access to ClSimplexSolver.ConstraintMap()
|
|
** Permit nested beginEdit()s and handle them correctly
|
|
|
|
* Miscellaneous changes
|
|
** Updated copyright to include 1999
|
|
** Fixed wrappers/Makefile for building Python wrapper
|
|
** Reference Anthony Beurivé's STk wrapper
|
|
** Fix Scwm URL
|
|
|
|
|
|
30-Jan-1999, Changes since Cassowary v0.22 (for release v0.23)
|
|
* Bug fix (see ChangeLog for details)
|
|
|
|
|
|
23-Jan-1999, Changes since Cassowary v0.21 (for release v0.22)
|
|
* Minor code cleanup, additions of comments.
|
|
|
|
|
|
14-Sep-98, Changes since Cassowary v0.2 (for release v0.21)
|
|
|
|
* Make compile cleanly using egcs-1.1b -- use typename, and drop
|
|
unused templated instantiation
|
|
|
|
* Improved guile interface: add a void pointer to the solver objects,
|
|
and let the guile wrapper use it to keep a pointer to the scheme-level
|
|
object; also added clv-attach! and clv-attached-object for attaching
|
|
an object to a cl-variable (somewhat redundant with guile's
|
|
object properties)
|
|
|
|
* Wrap ClStayConstraints so they can be managed explicitly
|
|
|
|
* cl-add-stay, cl-add-editvar now take strength and factor arguments,
|
|
instead of a list of cl-vars
|
|
|
|
* Added weight option to addEditVar
|
|
|
|
|
|
6-Aug-98, Changes since Cassowary v0.1 (for release v0.2):
|
|
|
|
* Changes to the distribution for release v0.2
|
|
|
|
** added guile/scheme wrapper of C++ version
|
|
|
|
** mention SCWM in README
|
|
|
|
** mention non-maintenance of Smalltalk implementation unless we have users
|
|
|
|
* Changes to the C++ and Java implementations
|
|
|
|
** Fixed several bugs -- dummy variables were wrongly being pivoted into
|
|
the basis, and constraints that threw required failure exceptions
|
|
were mistakenly remaining in the tableau (now trying to remove an
|
|
exception that was not added because of a required-failure exception
|
|
will correctly throw a ConstraintNotFound exception); more -- see ChangeLog
|
|
|
|
** Added a virtual change_value function to permit applications to watch
|
|
for changes made to external variables.
|
|
|
|
* Changes to only the C++ version (Java version will catch up in 0.3)
|
|
|
|
** Added new test cases to ClTests, fixed bugs in ClTestColumns
|
|
|
|
** Added _pv (void *) field hanging off of ClConstraint and ClVariable
|
|
for associating arbitrary structs with those (needed by SCWM)
|
|
|
|
** Permit nested beginEdit()s, and do the right thing upon calling
|
|
endEdit() -- i.e., not all the edit variables are removed, only the
|
|
nested ones
|
|
|
|
** Permit access to ClSimplexSolver::ConstraintMap() (used by
|
|
guile-wrapper to efficiently get at a list of constraints in the
|
|
solver)
|
|
|
|
** Added ExCLEditMisuse exception
