Joshua Clayton 8d5e13c89e Use sensible defaults for the CLI Why? ==== By default, people want to see an actionable, comprehensive list without having to pass any flags into the program. Previously, to see everything with high likelihood you'd need to provide `-a --likelihood high`. This commit changes the program so that's the default. It also introduces a `--all-likelihoods` flag (shorthand is `-a`) to see everything, so if you want to opt into see it, you can. Finally, this changes `-a` (to see everything) to `-s` (to see only single occurrences, which was the previous default).		2016-05-11 11:31:52 -04:00

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 install

This will generate a binary in $HOME/.local/bin; ensure this directory is in your $PATH.

To run the test suite, run:

stack test
