[cfe-dev] implementation of code completion and source code browsing for an IDE

[Jared Low]

We are using Clang as our compiler, and I'm implementing code completion 
and source code browsing, including:
goto definition
find all references to functions, variables, data types, and macros in 
project
call graphs
list of functions, types, macros, and variables in project and each source 
file
list of included files in each source file

I'm new to Clang, but in looking at the libraries, it seems I could use 
the clangIndex library for the source code browsing and the clangFrontend 
library for the code completion. The clangIndex library already has things 
that I need like the declReferenceMap and the callGraph.

I also found libclang, which seems to provide a lot of the basic 
functionality that I need as well.

My question is whether I should use libclang or the clangIndex and 
clangFrontend libraries?

Thanks for any help.
