Here is a quick rundown on setting up tab completion in vim for RubyMotion.
Configure ctags support
Using ctags with
vim can save us from
typing really long class or method name by hand. RubyMotion already includes
a rake task for generating ctags for a project, but first we need to ensure
the proper ctags executable is installed in the system. ctags can be installed
using a package manager. OSX users can inatall it using
~> brew install ctags
Generate RubyMotion ctags file
After ctags is installed run the following rake task from inside the root of the RubyMotion project directory.
~> rake ctags
This will generate the ctags file that we will use in vim to setup tab completion.
Setup vim for tab completion
supertab is a vim plugin which
allows you to use
Tab for all your insert completion needs. Once installed
there is no need to type those long class or method names anymore. Just type two
or three characters and press
Tab and it will use the ctags file to display a
list of matching names.
