Provide option for parsing function bodies #95
Description
Activity
Could an option be added to enable function body parsing? I'm happy to PR it myself, however, I don't know what other modifications would be required.
Adding such an option would require also to parse the full content, handle all the syntax elements, create all the associated AST classes. Unfortunately, I don't want to support this as it would require a significant amount of work - and maintenance.
This library is meant for parsing interfaces, signatures of methods and so mostly header files.Adding such an option would require also to parse the full content, handle all the syntax elements, create all the associated AST classes.

If I'm not mistaken, if function body parsing was enabled, could I get this information from the generic
CppToken? I don't need full function parsing; I just need to be able to get the_MTL_PRIVATE_SELcontained within.If I'm not mistaken, if function body parsing was enabled, could I get this information from the generic

I conducted an inital test with the following code:
[Test] public void TestComplex() { ParseAssert(@" #include <objc/runtime.h> #define _NS_PRIVATE_SEL(accessor) (Private::Selector::s_k##accessor) #define _NS_PRIVATE_DEF_SEL(accessor, symbol) extern SEL s_k##accessor namespace Private { namespace Selector { _NS_PRIVATE_DEF_SEL(test, ""test""); } } SEL method() { return _NS_PRIVATE_SEL(test); } ", compilation => { Assert.False(compilation.HasErrors); }, new CppParserOptions { SystemIncludeFolders = { "/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/c++/v1", "/Library/Developer/CommandLineTools/usr/lib/clang/15.0.0/include" }, AdditionalArguments = { "-isysroot", "/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk", }, TargetCpu = CppTargetCpu.ARM64, TargetSystem = "darwin", TargetVendor = "apple", ParseSystemIncludes = true, ParseMacros = true }); }
It seemed to run without errors, with the only problem being that the method's contents are not available in the AST yet. But I think it might be possible.
Hi there, I'm trying to use CppAst.NET to parse
metal-cppheader files, which are a wrapper of the Objective-C API. The underlying Objective-C functions being called are contained within a macro within the function body.To generate valid C# code, I need to be able to access the string used to generate the selector inside the function bodies, however currently, function body parsing is disabled.
