$ npm install -g git-precheck

You can use this from within any git directory to run basic pre-checks before making a commit:

$ git precheck
Installing node dependencies
Extracting build steps from travis

> [email protected] test /home/...
> node scripts/run-tests

# output of your commands...

Summary of build steps:
√  $ npm test
√  $ node scripts/generate-docs.js
√  $ git diff --quiet # make sure no files have changed

What commands does it choose to run? Well, it aims to run whatever Travis CI would attempt to run. How does it decide? Read below...

But wait, there's more! If you're a fugitive user, then you get vim-integration for free. You can run prechecks from within vim using:

:Git precheck " or if you were smart and made the short alias...

If you're not a fugitive user (but really, why not?) then you can use it like this:

:!git precheck

Yup! It works with Travis as well. If you have a .travis.yml file in your repo, it will attempt to read the script steps from the file and execute those sequentially, just like Travis would. Now you can know if your PR will pass before you push it 👍

Windows compatibility isn't my biggest priority, but it should still be there. If it isn't, drop me a line and let me know.
