ruby-align

A code formatter for Ruby to make alignment.

Usage

ruby-align your_program.rb
ruby-align --[f]ile=your_program.rb

Or it can receive input from STDIN and output formatted code.

How this works?

This script provides functionality of aligning code elements such as variable assignments or hash declarations.

Here's an example:

## before
a = 1
dddd ||= (1..3)
bb -= 20
e = { foo: 1, bar: 'Bar' }

stash = {
  foo: 123,
  'bar' => 'Bar',
  "bazz" => %w[ x y z ]
}

## after
a      = 1
dddd ||= (1..3)
bb    -= 20
e      = { foo: 1, bar: 'Bar' }

stash = {
  foo:      123,
  'bar'  => 'Bar',
  "bazz" => %w[ x y z ]
}

If you are curious, you can see formatting examples under spec/ directory. In spec/subjects/ directory, there are some unformatted code snippets. And formatted results of them are in spec/expects/ directory.

Call ruby-align in Text Editors

Because I am a vimmer, here is only example of .vimrc.

" == ruby-align ==
" set your favorite leader key
let mapleader = ","
noremap <Leader>ra <Esc>:%! /path/to/ruby-align<Return>
noremap <Leader>rav <Esc>:'<,'>! /path/to/ruby-align<Return>

If you add this into your .vimrc, you can call ruby-align to whole your buffer by typing ,ra. Or you can partially apply it by ,rav for selected area in visual mode.

Settings for other editors are welcome.
