## Installing
|
||||
|
||||
### Homebrew
|
||||
|
||||
You can install [my formulae] via [Homebrew] with `brew tap`:
|
||||
|
||||
```sh
|
||||
brew tap joshuaclayton/formulae
|
||||
```
|
||||
|
||||
Next, run:
|
||||
|
||||
```sh
|
||||
brew install unused
|
||||
```
|
||||
|
||||
[my formulae]: https://github.com/joshuaclayton/homebrew-formulae
|
||||
[Homebrew]: http://brew.sh/
|
||||
|
||||
Alternatively, you can install by hand.
|
||||
|
||||
### Stack
|
||||
|
||||
This project uses [Haskell] and [Stack].
|
||||
|
||||
Once you have these tools installed:
|
||||
|
||||
```sh
|
||||
stack setup
|
||||
stack install
|
||||
```
|
||||
|
||||
This will generate a binary in `$HOME/.local/bin`; ensure this directory is in
|
||||
your `$PATH`.

Unused leverages [Ag](https://github.com/ggreer/the_silver_searcher) to
