Module documentation for 0.4.3.3

There are no documented modules for this package.

homplexity

Aims to assess complexity and quality of Haskell code by measuring relative length of declarations, their depth, and code-to-comment ratio.

For parsing it uses haskell-src-exts, and cppHs.

Build Status Hackage Hackage Dependencies

Official releases are on Hackage

USAGE:

After installing with cabal install homplexity, you might run it with filenames or directories with your Haskell source

    homplexity Main.hs src/

Patches and suggestions are welcome.

You may run homplexity --help to see options.

How does it work?

Homplexity is based on the idea of Metrics that are applied to various CodeFragment types extracted automatically from parsed source. Each metric is then assessed whether it crosses any thresholds, and depending on them the severity of the message is chosen.

To see all metric values, set the warning --severity to INFO.
