LibClang is a stable high level C interface to the clang compiler.

LibClang is a stable high level C interface to clang.

When in doubt, LibClang is probably the best clang interface to use, since it:

  • can be called from any language interfaced with C (python bindings come out of the box),
  • is stable,
  • provides high enough abstraction over clang's implementation details.

LibClang provides the following features:

  • C/C++/ObjC/ObjC++ code parsing and syntax checking,
  • AST indexing and cross-referencing,
  • source code tokenization (e.g. for syntax highlighting),
  • code completion.

libclang/libtooling handle or turn off all error outputs

I think every thing is in the title^^ in fact, I'm developping a tool using libtooling, but I'd like to suppress every errors (the tool is aimed to be used only on correct source, so error output polutes stderr...).
