C++ Include Walker
The idea is to parse all of the #include statements in a set of .cpp, .cxx, .c, .h, .hpp, .hxx files, build a depencency forest and provide some functionality, such as
- finding circular dependencies (either using Johnson's alg, or during topo sort by Kahn's method),
- finding superfluous
#includestatements (superfluous in the sense of "include only what you need") - sort header files topologically.
In the long run, it would be awesome if this could be used to automatically generate .i files for swig.
Note
Other tools use a compiler to obtain the AST.
- Con: Additional dependency, how would you do this platform-independently?
- Pro: This would be useful to catch platform dependent includes and not make assumptions about include guards.
