fsource - Fortran static analysis tool

fsource is a collection of tools allowing you to parse Fortran 77 through Fortran 2008 programs. It is written in pure Python and has no external dependencies.

You install fsource via pip:

$ pip install fsource

or simply download the source, since there are no external dependencies (note that you should use bin/fsource instead of fsource in this case).

fsource currently features a command line interface:

• a parser, which takes a Fortran file and outputs an abstract syntax tree (for the definitions) allowing you to extract modules, subprograms, derived types, parameters, etc.:

  $ fsource parse FILE.f90
  

• a wrapper, which builds on the Fortran parser to extract module variables, types and subroutines which can be interfaced with C and generates header files for them:

  $ fsource wrap FILE.f90
  

• a line splicer and a lexer, low-level tools which split a Fortran file into a set of logical lines and tokens, respectively. This allows you to set up your parsing infrastructure on top of fsource:

  $ fsource splice FILE.f90
  $ fsource lex FILE.f90
