ochtra stands for One Commit Hook To Rule All and is an attempt at creating the definitive Git commit hook that:

• Works on all your languages (for now Ruby, JavaScript, TypeScript, CoffeeScript, Python, Sh, Bash, Dash, Go, Perl, PHP, XML, JSON, YAML, HTML)
• Is globally installable for all your repositories
• Aims to keep syntax errors from entering your codebase
• Is not religous about coding style (you still can have your own custom pre-ochtra hook for that)

ochtra deals with some common pitfalls you'll find in other hooks:

• Works on initial commits
• Will skip files that are staged to be deleted
• Will not run when we're not currently on a branch
• Can co-exist with your current commit hook, just rename it to pre-ochtra
• Works on filenames with spaces
• Checks files as staged in Git, not how they're currently saved in your working dir
• Deals with discrepancies between linters sometimes printing errors on STDOUT vs STDERR

Without installing anything, you can see ochtra in action on a local test repository:

cd /tmp
mkdir test-repo && cd $_

git init
curl -s https://raw.githubusercontent.com/kvz/ochtra/master/pre-commit -ko .git/hooks/pre-commit \
 && chmod u+x $_

echo ";-)" > syntax-error.go
git add syntax-error.go
git commit

You'll notice that ochtra won't let you commit that syntax-error.go:

Phew : ) Now for .go files it won't typically be a huge problem as your Go project won't run with syntax errors in the first place. But what about making that quick documentation change and leaving a typo? What about that Bash file in your repository? ochtra has got you covered.

As of Git 1.7 you can install ochtra as a git template.

mkdir -p ~/.gittemplate/hooks
curl https://raw.githubusercontent.com/kvz/ochtra/master/pre-commit -o ~/.gittemplate/hooks/pre-commit \
 && chmod u+x $_
git config --global init.templatedir '~/.gittemplate'

This will make it present in all newly create repositories.

Now, to install/update in existing repositories you can type

cd my-project
rm .git/hooks/pre-commit
git init # just copies any non-existing files from ~/.gittemplate to current repo

To remove ochtra from one project, type

rm .git/hooks/pre-commit

To remove the automatic installer for new Git repos, type

git config --global --unset init.templatedir
# git config --global --remove-section init

To run the tests:

make test

• Stefan Näwe (reporting issue)
• mihaeu (reporting issue)
• Mischa ter Smitten (curl fix for githubusercontent when installing)
• Jan Dorsman (fix PHP error logging)
• qdx (fix pipestatus & Git invalid object bug)
• Jostein Kjønigsen (TypeScript support)
• Dan Boulet (HTML support, improve YAML/Git/Go support and tests)

• If you already had a pre-commit hook that you want to preserve and have executed before ochtra, just rename it to pre-ochtra.

• If you ever want to commit code and disable the pre-commit one time, type

$ git commit -n

This can be useful if you import big chunks of code that don't pass jshint yet.

• If you want to install linters, have a look at the .travis.yml file, it has instructions for all of them
