- The upper char limit in Lexer.h was wrong. Now correctly set to 10FFFF.
- The lexer ATN simulator now uses lower + upper limit of char32_t instead of hardcoded values.
- Added a little hack to Interval, where a range ending with 0xFFFF will automatically be extended to 0x10FFFF. This is necessary until ANTLR generates full Unicode intervals. This hack allows to include Unicode chars beyond the BMP in char classes in a lexer.
- Fixed an error display issue in Lexer.
- Reversed the meaning of grammar sections members + declarations to maintain the same meaning for members between C++ and Java target. Now members are placed in the public section of a class, while declarations use the private section. This change helps to minimize language specific parts in grammar actions.
- Removed deleted cpp files from XCode project.
- Cpp.stg:
- Renamed all occurences of "result" back to "_localctx" as they appear in the Java.stg file. While the name "result" better fits the purpose the rename increases differences between targets, hence it was taken back, so we can use the same actions in all targets.
- TokenPropertyRef_text is now complete.
Some warnings in generated files cannot be fixed in a general way because usage of parameters depends on the grammar, hence we suppress unused-parameter warnings in the grammar (for lexer and parser files).
- @parser::context or @lexer::context are now also accepted for code that should be placed directly before the class declaration (e.g. additional types, like enums etc.)
- Reverted the removal of explicit EOF handling. Thought we can just live with the EOF macro, but that doesn't work out, so we go with the same approach as the ANTLR3 C target: #undef EOF and use EOF member constants as in the original Java code.
- Fixed a crash when trying to create a hash from a null parent in PredictionContext.cpp.
- Generated token and rule enums are now placed in the lexer/parser classes which allows to use them without qualfication within those classes, making so actions in a grammar more language independent. Outside code still has to use e.g. TParser::ID to access them.
- Made some lambda capture lists more explicit. Need to test yet if we can just use a default capture instead.
C++ target:
- More sections are now supported: pre + post include, declarations, definitions (in addition to header and members).
- Added specific variants of these sections for (base)listener + (base)visitor files (baselistenerpreinclude etc.).
Had to add named sections to VisitorFile.java + ListenerFile.java.
Also added the new namedActions parameter to all target stg files where needed.
- All allocations are now checked for proper deallocation.
- Ran LLVM analyzer over the runtime but it found mostly valid stuff and did not find non-freed allocations I left undeleted by intention. So it's not worth much.
- Added move and copy assignment operator overloading, as well as a copy c-tor to ATN class to avoid a copy (and to be able to free content properly) after deserialization.
- Some clean up.
- Removed ultra simple test grammar + parser. No longer needed.
- Removed long list of keywords from (regular) test grammar.
- Fixed a number of toString() methods to get better debug output.
- Moved Ref typedefs from Declarations.h to the individual classes as defining them on the forward declarations totally confuses the XCode debugger.
- Removed reference to the owning ATN in an ATNState. We cannot guarantee to have the correct address there due to the way the states are created. The reference is not needed anyway.
- ATNDeserializationOptions now has verifyATN set by default (as in the Java target).
- Had to add a workaround for a weird situation: static initialization in ATNDeseralizer stopped working for no apparent reason. Need to investigate this.
- Added a few support methods to the CPPUtils, mostly to ease debug output creation.
- Added console listener by default to the listeners list (as done in the Java target).
- Fixed translation mistakes in the CommonTokenStream class.
- Fixed some memory leaks and exception handling bugs.
- Removed a few unused classes.
- More raw pointers to smart pointers conversion: RuleContext, ParserRuleContext, ParseTree, Token, ParseTreeWalker, Tree...
- BitSet is now used directly instead of all those dynamic allocations and is a derived class instead of a composite.
- Replced ATNState equals with == operator overload.
- Correct wrong iterator over ATNConfigsets.
- Added utilitiy function that mimics Java's generic toString().
- Added IntervalSet unit tests. Fixed a few bugs found by that.
- Enhanced the demo grammar so that we use as many as possible template rules from Cpp.stg. Still not fully done it seems.
- Fixed bugs in size determination for arrays (vectors now).
- Simplified PredictionContext and SemanticContext (one template parameter less).
- Removed no longer used Utils.h/cpp. Fixed CPPUtils.h/cpp.
- Extended LexerXXCommand template rules to take a new grammar parameter (code gen has been updated) as we need this context in the Cpp target. This change requires to update all existing templates! Cannot do here as this is an old revision.
- Some cleanup.
- ATN deserialization finally works.
- Changed a number of pointer to STL classes to just the STL classes and pass them around by const & where necessary.
