pfff

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 preliminary support
for Javascript, C, C++, Java, and other languages. There is also
preliminary support for OCaml code so that the framework can be used
on the code of pfff itself.

For each languages there are mainly 2 libraries, for instance
parsing_php.cma and analysis_php.cma, that you can
embed in your own application if you need to process PHP code. See the
demos/ directory for example of use of the pfff API. See also
docs/manual/Parsing_xxx.pdf and docs/manual/Analyzis_xxx.pdf for 
more documentation on how to use or extend pfff.

pfff is also made of few tools:
 - pfff, which allows to test the different parsers on a single file
 - scheck, a bug finder
 - stags, an Emacs tag generator
 - sgrep, a syntactical grep
 - spatch, a syntactical patch
 - codemap, which is a gtk and cairo based source code
   visualizer/navigator/searcher leveraging
   the information computed previously by pfff_db and codegraph.
 - codegraph, a package/module/class dependency visualizer
 - 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 global analysis on a set of source files and
   store the data in a marshalled form in a file somewhere (e.g. /tmp/db.json)

For more information, look at the pfff wiki here:

as well as the docs/manual/ directory.

Usage for pfff:
-----------------

   $ ./pfff -parse_php demos/foo.php 

or

   $ ./pfff -dump_php demos/foo.php 

You can also look at ./pfff --help

Usage for pfff_db:
-------------------

   $ ./pfff_db -lang ml -o /tmp/pfff.json ~/pfff

to analyze all the .ml and .mli files under ~/pfff and store metadata
information (the database) in /tmp/pfff.json

Usage for codemap:
------------------------

  $ ./codemap ~/pfff

This should launch a gtk-based GUI that allows you to visualize
source code and perform some code search.

Usage for codegraph:
------------------------

  $ ./codegraph -lang cmt -build ~/pfff

to generate a graph_code.marshall file in ~/pfff containing
all dependency information about the pfff codebase using the
typed bytecode .cmt files generated during the compilation of pfff.

  $ ./codegraph ~/pfff

This should launch a gtk-based GUI that allows you to visualize
source code dependencies.
