Sublime Text Snippets
16 Apr 2014One way to work faster is to have predefined snippets or blocks of code help you with repetitive typing.
How to use Snippets in Sublime Text:
In sublime text you can install these by going to Tools => New Snippet...
This will give you a confusing XML document looking like this:
<snippet>
<content><![CDATA[
Hello, ${1:this} is a ${2:snippet}.
]]></content>
<!-- Optional: Set a tabTrigger to define how to trigger the snippet -->
<!-- <tabTrigger>hello</tabTrigger> -->
<!-- Optional: Set a scope to limit where the snippet will trigger -->
<!-- <scope>source.python</scope> -->
</snippet>
The text in between the [CDATA[ and ]] are what you want to edit.
The $1 or ${1:this} are where the cursor will be after you activate the snippet. This text after the : is the default and you can get to $2 by tabbing.
The word you’d like to trigger the snippet should go here (in this example, ‘hello’ + Tab).
Scope determines which files the snippet will work on. The scopes that I use most often and available to Sublime Text include source.ruby, source.ruby.rails & text.html.erb.
Keyboard Shortcuts
If you feel the need, you can bind the snippet to a keyboard shortcut. This would involve adding a line to your ‘Keybindings - User’ file (found under Sublime Text => Preferences).
Here’s the sort of thing you’d want to add:
{ "keys": ["alt+shift+e"], "command": "insert_snippet", "args": {"name": "Packages/User/my-clever.sublime-snippet"}}
Be careful to make sure it’s in a vaild JSON array - eg. watch out for commas & make sure there are square brackets enclosing everything.
