Unused 
A command line tool in Haskell to identify unused code.
Installing
Homebrew
You can install my formulae via Homebrew with brew tap:
brew tap joshuaclayton/formulae
Next, run:
brew install unused
Alternatively, you can install by hand.
Stack
This project uses Haskell and Stack.
Once you have these tools installed:
stack setup
stack install
This will generate a binary in $HOME/.local/bin; ensure this directory is in
your $PATH.
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.
Requirements
Unused leverages Ag to
analyze the codebase; as such, you'll need to have ag available in your
$PATH. This is set as an explicit dependency in Homebrew.
Testing
To run the test suite, run:
stack test
