This project contains step definitions that can be used to spawn a Vim instance and control it through code. The actual work is done by the vimrunner gem.
Here's an example feature from my plugin splitjoin:
Feature: CSS support
Scenario: Splitting single-line style definitions
Given Vim is running
And the splitjoin plugin is loaded
And I'm editing a file named "example.css" with the following contents:
"""
h2 { font-size: 18px; font-weight: bold }
"""
And the cursor is positioned on "h2"
And "expandtab" is set
And "shiftwidth" is set to "2"
When I split the line
And I save
Then the file "example.css" should contain the following text:
"""
h2 {
font-size: 18px;
font-weight: bold;
}
"""
It's a bit verbose, but it's work in progress.
For now, there are only a few steps in lib/cucumber/vimscript.rb. I'll add
more and organize them as I attempt to use this project for testing some of my
own scripts. Any contributions are more than welcome, though.
