If your generation tool is in Java, consider using the parser from the Eclipse CDT.
my set of dependencies are:
- com.ibm.icu_4.4.2.v20110823.jar
- org.eclipse.cdt.core_5.3.2.201202111925.jar
- org.eclipse.equinox.common_3.6.0.v20110523.jar
(these are from an old Eclipse version, because I have a dependency on old java class versions), but taking from the latest CDT wil do.
parsing involves:
FileContent reader;
reader = FileContent.createForExternalFileLocation(fullPath);
IScannerInfo info = new ScannerInfo(definedSymbols, includePaths);
return GPPLanguage.getDefault().getASTTranslationUnit(reader, info, FilesProvider.getInstance(), null, 0,log);
This returns an IASTTranslationUnit that can be accessed through a Visitor pattern (ASTVisitor).
I cannot comment on the accuracy of the parsing in corner scenarios, because so far I've been generating code based on simple C++ structure definitions.
