## Running on Hackage
|
||||
|
||||
It's possible to try Ormolu on arbitrary packages from Hackage. For that
|
||||
execute:
|
||||
|
||||
```console
|
||||
$ nix-build -A hackage.<package>
|
||||
```
|
||||
|
||||
Then inspect `result/log.txt` for possible problems. The derivation will
|
||||
also contain formatted files for inspection.
