Tools and APIs for program analysis, code visualization, refactoring

pfff is a set of tools and APIs to perform some static analysis, dynamic analysis, code visualizations, code navigations, or style-preserving source-to-source transformations such as refactorings on source code. For now the effort is focused on PHP but there is also good support for C, C++, Java, HTML, Javascript, Css, and preliminary support for Erlang, Python, C#, Lisp, Scheme, Haskell, OPA, Sql, and even TeX. There is also very good support for OCaml and noweb (literate programming) so that pfff can be used on the code of pfff itself.
