check: set HOME to a tmp dir to avoid polluting the working dir#551
Conversation
pre-commit creates cache files in $HOME/.cache/pre-commit. If $HOME is set to $PWD, we will pollute the working directory, causing hook failures. Previously, we would copy the source files into a nested `src` directory. Now that Nix already provides the source files in the working directory for us, to avoid another copy, we set $HOME to a temporary directory.
