Document the minimum cmake version needed to build C++ target (if compiling with cmake). Also, fix a missing space in cmake command between directory path and defining where the ANTLR .jar is located.
The root cause was that ATNConfigSet was not using he required custom hashing strategy for ParserATNSimulator.
The commit includes a number of additional fixes, related to code that was never executed before due to the root cause.
A similar issue is also likely to exist in the JavaScript runtime, I'll fix it later.
- The previous approach to load and convert UTF-8 data via a stream didn't work well, so I replaced that with a simple load-to-buffer + convert buffer from UTF-8 to UTF-32.
- Removed deleted Token.cpp file from XCode project.
- Created deployment script for Windows + updated doc/releasing-antlr.md.
- Created projects for both VS2013 and VS2015 to be used by the deployment script.
- Fixed trouble with a bug in VS2015 where std::codecvt_utf8<char32_t> is not properly supported.
- Fixed a few #include paths + a number of warnings.
- Settled on a final library name scheme: base part is "libantlr4-runtime" on MacOS + Linux. The extension determines the type (.a static lib, .dylib dynamic lib in MacOS, .so dynamic lib in Linux). No more mention of target language (cpp) or type (static) in the lib name. On Windows we omit the lib prefix, so the name becomes: antlr4-runtime.dll + antlr4-runtime.lib. We may later want to add version information there, but doing that automatically is difficult.
- Updated XCode project and CMakeLists.txt file for the new naming scheme.
- Added deployment scripts for source code (for Linux + iOS) and MacOS.
- Added C++ section in docs/releasing-antlr.md.
No need to use shared_ptr for management. Listeners are, like the other main classes (parser, lexer, input stream etc.) provided by the application and hence managed there.
In order to lower the overhead when passing around Token instances via smart pointers and because the ownership is clear (token streams own them), these instances can be passed as raw pointers.
No need for the ConfigLookup(Impl) class as we only need a way to determine if a config has been added to a set or not. This can be done much simpler by using individual hash codes produced by either ATNConfigSet or OrderedATNConfigSet (idea taken from C# runtime).
ATNConfigSet instance follow a clear ownership (all owned by DFAState instances, which stay alive all time). Hence we can use a unique_ptr for memory management instead and pass raw pointers around where needed.
All shared_ptr<> now use const& for function parameters to avoid constant copies + locks. Ownership and lifetime control is still ensured by the owning containers. Code templates have been updated as well.
- Changed namespace chain (org::antlr::v4::runtime) to just antlr4 in all files.
- Fixed runtime tests for that.
- Added conversion of the xpath code, which compiles now (no tests, tho, as there are runtime tests for it).
- Removed TestRig stuff. That doesn't work in C++.
- Avoiding double semicolons is tricky with the kind of rule nesting. Previous changes for that caused the tests to break as there were semicolons missing then.
- VS complained about the shift code generated using 1L as base, which is signed. Changed that to 1ULL, which is what is actually intended.
- Reverted the change to avoid a warning in RuleSempredFunction() in Cpp.stg as the fix didn't work 100%. We need a different solution.
- A few remaining changes had to be done for the C++ runtime tests which now completely pass.
- Added a runtime testing overview document.
- Added a description of C++ target.
- Updated the ANTLR release document.
