Here are the pfff tools:
pfff, a small command line program to test the different programming language parsers
scheck, a lint-like bugs finder
stags, a more precise Emacs tag generator
sgrep, a syntactical grep, to make it easy to find precise code patterns
spatch, a syntactical patch, to make it easy to refactor code
codemap, a semantic source code visualizer/navigator/searcher which can also leverage the information computed by
codegraph. See Examples and Examples2 for screenshots of the tool applied to many different open source projects.
codegraph, a package/module/class dependency visualizer as well as a source code indexer (a.k.a grapher)
codequery, an interactive tool a la SQL to query information about the structure of a codebase using Prolog as the query engine
pfff_db, which does some simple global analysis on a set of source files and store the data in a marshalled or JSON form in a file somewhere (e.g.

pfff is a continuation of the work I've done on coccinelle, an advanced refactoring tool for C http://coccinelle.lip6.fr/ I co-designed with Julia Lawall.
