KDevelop-PG-Qt lexer-branch merged into master
Hi folks!
I have finally merged my private lexer-branch of KDevelop-PG-Qt into the master-branch and pushed it to git.kde.org – after having run KDevelop-php-plugin unit-tests 
. Well, what are the changes?
- Now there is support for lexer-generation, including unicode-support (UTF-8, UCS-2, UTF-16, UTF-32/UCS-4). I have talked about those features in some previous blog-posts.
- You do not have to use “;;” any longer, just “;” will work, but for compatibility “;;” will be like a single semicolon.
- Fixed a very old overflow when reading the grammar from an input-stream
- With –error-aware-code (the default) error-messages will now work correctly, when you are compiling the generated file and there is an error in your hand-written code, you will get correct references to the corresponding line in the grammar-file, unfortunately kdev-pg-qt’s error-messages are still not perfect (wrong column-numbers etc.).
- Added some command line options, marginal changes in their behaviour
- Changed some messages (spelling etc.)
Maybe, some day, there will be KDev-PG-Qt 1.0 (currently it is called 0.9.5 ), so, what is still to do?
- Make it possible to control what should happen when the lexer fails (it should not just be exit(-1))
- Update the documentation at Techbase
- Update the Kate-syntax-file
- Decide which additional unicode-character classes are useful, add some aliases
- Make new command-line-options available in the CMake-macro
- Find out, how to enable C++0x support in CMake allowing different compilers (yes, I am using variadic templates )
- Tokens should no longer be declared inside the parser-class (of course it should still be possible for compatibility)
- Forward-declarations for AST-classes
- Integration with QIODevice/KIO (optional)
- Dumping automata (optional)
Of course there could be more nice stuff, but that would not be related to the recent changes, e.g. LL(k)/LL(*)-parsing, look-ahead, possibility to switch rules off, packed AST-nodes, making it usable as a library etc.
I hope there are really no regressions, and the changes will be useful for the small elite of KDevelop-PG-Qt users.

Thank you very much, how could I forget that… Added it.

Thanks. Maybe you have a suggestion for the build error seen with the new snapshot:
https://build.opensuse.org/package/rawlog?arch=x86_64&package=kdevelop4-pg-qt&project=KDE%3AUnstable%3APlayground&repository=openSUSE_11.2_KDE_Unstable_SC

Which gcc-version are you using? I tried to compile kdev-pg-regexp.cpp with the same flags, also x86_64, and it worked.

Okay, we discussed it in IRC and fixed it, gcc 4.4.1 does not like certain kinds of static-template-member-initializations (TableCharSet::nullData).
