Bash completion support for Rake, Ruby Make.

 $ rake st<Tab>
 $ rake stats

 $ rake test<Tab><Tab>
 test              test:integration  test:recent       
 test:benchmark    test:plugins      test:uncommitted  
 test:functionals  test:profile      test:units

It caches tasks to .rake_tasks~ file, which makes it faster from default completion from Ubuntu rake.

If Rakefile is not present in current directory, autocomplete will try to locate it in parent directories up to filesystem root, so running tasks is also possible from subdirectories.

Obsolete: the package is no longer available at PPA.

1. Add Ubuntu on Rails PPA:

    $ sudo add-apt-repository ppa:ubuntu-on-rails/ppa
    $ sudo apt-get update

2. Install rake-completion package:

    $ sudo apt-get install rake-completion

Make sure you are running an up-to-date bash version (at least 4.3).

Installing bash and bash-completion with homebrew run:

$ brew install bash bash-completion

Then install this script:

$ curl -o /usr/local/etc/bash_completion.d/rake https://raw.githubusercontent.com/ai/rake-completion/master/rake

Copy rake script to /etc/bash_completion.d/.

$ wget -O /etc/bash_completion.d/rake https://raw.githubusercontent.com/ai/rake-completion/master/rake

Copy rake script (for example, to ~/scripts/) and add to your .bashrc:

. ~/scripts/rake

Tasks cache in .rake_tasks~ file is placed in directory with Rakefile and will be updated on changes in Rakefile or any *.rake files.

To remove tasks cache (and another backup files) from Git repository add *~ to .gitignore file.
