Automatically generates FORtran Documentation from comments within the code.

FORD

This is an automatic documentation generator for modern Fortran programs. FORD stands for FORtran Documenter. As you may know, "to ford" refers to crossing a river (or other body of water). It does not, in this context, refer to any company or individual associated with cars.

Ford was written due to Doxygen's poor handling of Fortran and the lack of comparable alternatives. ROBODoc can't actually extract any information from the source code and just about any other automatic documentation software I found was either proprietary, didn't work very well for Fortran, or was limited in terms of how it produced its output. f90doc is quite good and I managed to modify it so that it could handle most of Fortran 2003, but it produces rather ugly documentation, can't provide as many links between different parts of the documentation as I'd like, and is written in Perl (which I'm not that familiar with and which lacks the sort of libraries found in Python for producing HTML content).

The goal of FORD is to be able to reliably produce documentation for modern Fortran software which is informative and nice to look at. The documentation should be easy to write and non-obtrusive within the code. While it will never be as feature-rich as Doxygen, hopefully FORD will be able to provide a good alternative for documenting Fortran projects.

Capabilities

Current features include:

• the ability to extract information about variables, procedures, procedure arguments, derived types, programs, and modules from the source code.
• the ability to extract documentation from comments in the source code.
• LaTeX support in documentation using MathJax.
• searchable documentation, using Tipue Search.
• author description and social media (including Github!) links.
• links to download the source code.
• links to individual files, both in their raw form or in HTML with syntax highlighting.
• use of Markdown to type-set documentation.
• links between related parts of the software.
• Bootstrap CSS for the documentation, making it both functional and pretty.
• configurable settings.
• ability to create a hierarchical set of pages containing general information, not associated with any particular part of the source code.
• display an entry for non-Fortran source files with file-level documentation and syntax highlighted code.

Installation

The simplest way to install FORD is using pip:

pip install ford

Pip will automatically handle all dependencies for you. By default this will place ford in ~/.local/bin -- you might need to add this to your PATH.

Alternatively, FORD is available through the Homebrew package manager for Mac OS X. To update Homebrew and install FORD, run these commands in a terminal:

brew update
brew install FORD

If you would like to install the latest development (master) branch from github, simply add the --HEAD flag: brew install --HEAD FORD

FORD is also available through the spack package manager by running the following command:

spack install py-ford
