Changes with Antlr 2.7.7
# Terence Parr
* updated BaseAST.java to make the doWorkForAll method static. Same
behaviour, except no ClassCastExceptions when sibling.getFirstChild()
happens to return an AST that doesn't extend BaseAST. Oliver Wong contributed
the patch.
* updated TokenStreamRewriteEngine.java to reflect bug fixes discovered
in v3 counterpart.
# Wolfgang Haefelinger
* changing version to 2.7.7
* configure*,scripts/csc.sh.in,*/AssemblyInfo.cs
building of strong assemblies supported - default is building of
"weak" assemblies as before. Option --with-strong-assemblies=ARG
enables strong assemblies (ARG must point to a keyfile). Such an
assembly allows to be called by a partially trusted caller. This
can be disabled by --disable-allow-partially-trusted-callers (if
APTC is disabled, examples may not compile if located on network
drive).
* antlr/Makefile.in: couple of missing *.java files - missing in 2.7.6 -
added.
* examples/cpp/heteroAST/*: fixed problem of missing include dir; example
compiles and tests fine.
* examples/cpp/Makefile.in: enabled all directories (+ heteroAST and
flexLexer).
* configure*, scripts/config.deps.in: fixes to reflect directory naming
changes in C#.
* examples/csharp/Makefile.in: disabled "broken" example HTML.
* lib/python/antlr/antlr.py: fixed "hideen" type reported by Andrew
McCulloh
Changes with Antlr 2.7.6
# Terence Parr
o added size, index methods to TokenStreamRewriteEngine.java
o bug in syn preds for tree parsers. Submitted by Ole Kniemeyer.
o all Class.forName yanked out; uses thread context loader
o option to prevent System.exit termination
o added recover() method to lexers
o fixed code gen bug for syn preds in tree parsers. Thanks to Marc Horowitz.
o BaseAST was not checking for null text in toString()
o Scott added java line ouput in code gen
o Prashant tweaked a few things for ANTLRStudio; a few new classes in ASdebug package
# Ric Klaren:
- Give errors if the user attempts to set k>1 in a TreeWalker
- Added missing Makefile.in for C++ heteroAST example and enabled it
in configure.in
- Many small C++ support code and codegen tweaks fixes to increase
portability. (Compaq Tru64 UNIX V5.1, VC's)
- Prevent '\' entering the bitset dump comments, might occur at end of
line. Some compilers continue the comment to the next line (not sure
if this is a compiler bug, should look it up)
For the thanks & kudos:
Among others thanks to Stuart Dootson, Bryan Ewbank, Kurt McCall and
a number of others who submitted patches. (my administration wasn't too
well this time)
# Wolfgang Haefelinger
*) configure.* : support for 'fastjar' added -fastjar will be preferred
if jar and fastjar are available [geronimo, Nov 30th 2005].
*) configure.*: fixed --with-bootclasspath error; configure --help
incorrectly displayed this option as "--bootclasspath". Thanks
to Paul Jenner for reporting [geronimo, Nov 13th 2005].
*) antlr/PythonCodeGenerator.java: fixed problems with raising
exceptions `SemanticException' and `MismatchedTokenException'
unknown in current namespace. Thanks to Klaas Hofstra and
Benjamin Niemann for reporting [geronimo, Nov 13th 2005].
*) examples/python/tinybasic/basic.g: fixed the unary MINUS problem
reported by Klaas Hofstra [geronimo, Nov 13th 2005].
*) configure*,scripts/[cxx|link].sh.in: Changes made by Kurt McCall
added to support Tru64 Unix (version V5.1, Rev. 732) along with
COMPAC/DEC CXX (version V6.5-042) [geronimo, Nov 13th 2005].
*) antlr/PythonCodeGenerator.java: 'inputState.guessing' bug reported
by Chris Minnoy and Benjamin Niemann fixed [Mark Kole, Jul 4th 2005].
*) lib/python/antlr/antlr.py: removed all 'tabs'; applied changes of patch
`1126872211596/antlr.py.patch' regarding getting line and column number.
Unknown patch contribution [geronimo, Nov 13th 2005].
# Changes for C# support (by Kunle Odutola & Micheal Jordan):
-- Fixed isssue where an empty input stream caused an exception in the lexer
due to the
caching of LA1 and LA2. StringTemplate triggers this.
-- The rewind() method did not take into account the value of the case
insensitive flag.
Reported by Dr. Hartmut Kocher.
-- ***BREAKING CHANGE*** ASTPair object pool had a race condition in
multi-threaded
environments. ASTPair is now a struct.
-- C# examples now properly initialize the ASTFactory before a tree parser
is used.
