Meathook

Meathook is a gem to help manage a living set of githooks. Inspired by Babar (http://github.com/jdabbs/babar), but intended to be more general in purpose.

.hooks

The .hooks.yaml file should be committed in the root of your repository - it's a yaml file like so:

---
path: "bin/meathook"
pre-commit:
  no_focus:
    command:   "git diff --cached spec/ | grep '^+' | grep ':focus'"
    condition: "nonempty"
    halt:      true
    message:   "You are trying to commit a focused spec!"
post-merge:
  remember_to_bundle:
    command: "git diff --name-only HEAD^..HEAD | grep Gemfile
    condition: "nonempty"
    halt:      false
    message:   "Gemfile was just updated - remember to run 'bundle install'"

Each hook type can be a toplevel key in that file, and the keys in each are arbitrary names of tasks. Each task then has the keys:

• command: command to run - output and exit code can both be relevant
• condition: one of [nonempty, empty, failed, successful]
• halt: under those conditions, should we halt the procedure? (commit, merge, etc)
• message: message to show the user if the condition is true

The 'path' key is special, and is used to supply a literal path to the meathook script, so that your githooks don't have to use bundler (which can add a half-second onto each operation). if which meathook doesn't give you a path, then you need to specify a path with this key.

meathook install

In order to run the githooks, meathook needs to install a self-call into each of the .git/hooks scripts of the form meathook execute <hookname>.

meathook uninstall

Removes the meathook call from all of the githooks.
