Unused

A command line tool in Haskell to identify unused code.

Using Unused

unused reads from a pipe expecting a series of tokens to search the codebase for.

This could be done with echo:

echo "module\nimport" | unused

Or pulling in a ctags file:

cat .git/tags | cut -f1 | sort -u | unused

My end goal is to have the latter rolled up into unused itself, so you can navigate to a directory, run unused, and everything works as expected.

This project uses Haskell and Stack.

Once you have these tools installed:

stack setup
stack build

This will generate a binary in .stack-work/install/**/**/**/bin that you'll want to move to somewhere in your $PATH.
