Hi, Let me explain what I needed it for. I was working on a tool that uses annotations as a source of "configuration" that can tweak the process of AST analysis/usage. Since the configuration can be complex I need to parse the annotation string to extract necessary information. I wanted to reuse CLang's infrastructure for diagnostics (maybe lexing too) to provide user friendly output. Right now (with const char* + length) the best thhing I could do is to setup completely independent DiagnosticsEngine/Lexer/Preprocessor etc. There is no connection with existing source code to have useful diagnostics with line numbers etc. On the other hand if I have StringLeteral I can extract necessary information about location of the string.
I'm new to clang, so maybe there is simpler solution that I don't see yet. I will appreciate any suggestions.
