bizoo/sublime-switch

A simple Sublime Text 2 plugin to switch segments of text with predefined replacements.

Intro

Switch for Sublime Text 2 was inspired by Andrew Radev's switch.vim.

The main entry point of the plugin is a single command, Switch. When the command is executed, the plugin looks for one of a few specific patterns under the cursor and performs a substition depending on the pattern.

Install

• Clone this git repository into your packages folder
• Restart Sublime Text 2 editor

Or with package control:

• Package Control: Add Repository https://github.com/robbl/Switch
• Package Control: Install Package Switch
• Restart Sublime Text 2 editor

Usage

If the cursor is on the keyword "true" in the following Ruby example, and the command is executed the "true" will turn into "false" and the other way around.

attribute = true
hash = { key: true }

Key Bindings

• OSX: <super+ctrl+s>
• Linux: <ctrl+alt+s>
• Windows: <ctrl+alt+s>

Customization

The following examples show how to customize the available switches. Switches are grouped together and should be considered as toggle groups. Your are required to do so for the full experience of this plugin.

There are two types of toggle groups:

• Simple toggle groups

  ["true", "false"]

  The first string comparison that matches a group item will substituted by the following item. (Note: If the end is reached it starts at the beginning.)

• Advanced toggle groups

  {
    ":(\\w+)\\s=>": "\\1:",
    "(\\w+):":      ":\\1 =>"
  }

  The first regular expression (the key) that matches the current line will be substituted by the replacement (the value).

Toggle groups are defined in the sublime-settings files as follows:

{
  "switch_custom_definitions": [
    ["if", "unless"],
    {
      "def (\\w+)\\s(.*)":    "def \\1(\\2)",
      "def (\\w+)\\((.*)\\)": "def \\1 \\2"
    },
  ]
}

And its possible to overwrite the builtin switches as follows. Sometimes you need or want to do that, because builtin switches overrule custom switches.

{
  "switch_builtin_definitions": [
    ["foo", "bar", "baz"],
  ]
}

Your also can have a look at your current or the default settings through the Sublime Text 2 Menu under Preferences / Package Settings / Switch. As usual User specific settings overrule Switch Package specific settings. The defined switches are prioritized in the following order (Note: Last weighs heaviest.) and grouped syntax specific.

• Packages/Switch/Ruby.sublime-settings
• Packages/User/Ruby.sublime-settings

Key Bindings

Include the following key binding definition in your sublime-keymap file and customize the keys.

[
  {
    "keys": ["super+ctrl+s"], "command": "switch"
  }
]

Builtins

Here's a list of all the built-in switch definitions. To see the actual definitions with their patterns and replacements, look at the corresponding sublime-settings file.

Ruby

Ruby.sublime-settings and [Ruby on Rails.sublime-settings](https://github.com/robbl/Switch/blob/master/Ruby on Rails.sublime-settings)

• Boolean conditions:

  foo && bar
  foo || bar

• Boolean constants:

  flag = true
  flag = false

• Hash style:

  foo = { :one => 'two' }
  foo = { one: 'two' }

• If-clauses:

  if predicate?
    puts 'Hello, World!'
  end
  
  if true and (predicate?)
    puts 'Hello, World!'
  end
  
  if false or (predicate?)
    puts 'Hello, World!'
  end

RSpec

RSpec.sublime-settings

• should/should_not:

  1.should eq 1
  1.should_not eq 1
  

Python

Python.sublime-settings

• Boolean constants:

  flag = True
  flag = False

Roadmap

• Add global (not language specific) switch definitions

Disclaimer

Since this plugin is in a very alpha state be warned: The way settings are defined and applied could and sure will change in the future.
