ABOUT

Cowl is a command line program for identifying text lines that are considered too long, wider than the conventional column width 80 or so.

cowl is a shell wrapper around the traditional GNU grep backend, presenting a frontend similar to modern linters like Reek and JSHint.

Recursive file search by default
Optional ignore patterns
Configuration via per-project and per-user dotfiles
Install via a standard programming language package manager
