Bash completion support for Ruby on Rails.
The completion routines provide support for completing:
- rails commands (e.g.: new, server, console, generate, runner, ...)
- rails generators (e.g.: scaffold, controller, mailer, observer, ...)
- rails environments
- rails field's types on generators (e.g.: scaffold, model, migration, ...)
- common --long-options
- Copy the
rails.bashfile to somewhere (e.g. ~/.rails.bash).
Add the following line to your
Alternatively, on Debian systems, you can just copy the
rails.bash file to
- Rails 3
Current version of
bash_completion supports all command-line options available in Rails 3.2.x, if you want to use it with Rails 3.0.y or 3.1.z you should check this version:
Typical usage is to change into a rails application and get some work.
For example, using rails console is something like:
$ cd rails_app $ rails c<Tab><Tab> c console $ rails c <Tab><Tab> --debugger development production -s --sandbox test $ rails c p<Tab> $ rails c production
Choosing the server's environment:
$ rails server -e<Tab><Tab> -edevelopment -eproduction -etest $ rails server -ep<Tab><Tab> $ rails server -eproduction
Playing with generators
The generators available for completion are not hard-coded. The
rails.bash script lookup for generators in your Rails application. In this way, generators provided by thrid-party plugins declared in your
Gemfile also will be available for completion. Moreover, for the sake of performance, the
rails.bash script saves the list of generators available in a cache file, named
.rails_generators~. But, if the
Gemfile file is modified the cache file will be updated on next completion event.
In the following example, I use the 'devise' plugin on
$ rails g <Tab><Tab> active_record:devise generator model resource controller helper mongoid:devise scaffold devise integration_test observer scaffold_controller devise:install mailer performance_test session_migration devise:views migration plugin stylesheets
In some generators (scaffold, model, resource and migration), you can declare fields to be generated using the syntax
rails.bash script also provides support for field's type completion. For this, just type the field name followed by a colon (
:) and hit
$ rails g model Blog title:<Tab><Tab> title:binary title:datetime title:integer title:time title:boolean title:decimal title:string title:timestamp title:date title:float title:text $ rails g model Blog title:s<Tab> $ rails g model Blog title:string ...
For more details, use it and have fun!
