CLI tool that checks the build status of current branch on Travis CI

Check build status of a project on the command line

Install (copy & paste):

curl -sL > ~/bin/travis-ci \
  && chmod +x ~/bin/travis-ci

gem install hub | tail -2
ruby -e 'require "json"' 2>/dev/null || gem install json

You're in a project's directory. Is the current branch green on Travis CI? Let's find out:

$ travis
origin/master built OK.

To check a branch other than current:

$ travis feature
origin/feature built OK.

The travis command will exit with a non-zero status if the latest build has failed or is still running. This enables you to chain the command like this:

$ travis && rake release

Now if the build has failed, rake release will never happen and this gives you the chance to fix your library before releasing the gem.
