Basic git pre-commit hook that runs gometalinter for all files staged for commit. When the linter raises any issues, the hook requires confirmation before proceeding with the commit.

Installation is easy. Just save pre-commit to your repository's hooks directory and make sure it has permissions to execute. The file should typically be at .git/hooks/pre-commit (relative to your repository, obviously).

cd /path/to/your/repo
curl -S https://raw.githubusercontent.com/epels/gometalinter-pre-commit/master/pre-commit > .git/hooks/pre-commit
chmod +x .git/hooks/pre-commit

Note: this will overwrite your existing pre-commit hook, if you have one.

$ git add main.go
$ git commit -m "Some message"
gometalinter raised issues:
main.go:5:6:warning: func someUnusedFunc is unused (U1000) (megacheck)
Would you like to proceed committing? (y/n) n
Aborting commit

• If you git add a file and modify it afterwards, it will run the linter for the current state.
