Textmate2 - How to put spaces between curly brace { } by default

Question

I'm developing Ruby on Rails application in Textmate2. I have to use a lot of curly braces {} syntax in Rails coding.

By default, when I type opening curly brace { , then {} is automatically displayed. In most Rails tutorial, it is so conventional to put spaces between curly braces at the start and end positions. For e.g.,

{ name: "aaa", email: "aaa@gmail.com" } # hash example
it { should have_selector('p', 'some text') } # rspec example

It's a little tiring to put spaces by hand in every coding sentences. I want to put spaces between curly braces automatically. I mean when I type { , I want { } to be appeared by default.

I don't know which bundles do I need to modify. Please show me ways how to be get done this syntax.

Answer 1

To do this you'll need to create your own snippet:

Open the Bundle Editor and select Ruby from the list. Press Command + n to create a new item, select Snippet from the drop down.

Name your new Snippet something appropriate, "Spaced Curly Braces" perhaps. The snippet editor should contain only:

{ $0 }

Click, in the Bundle Editor drawer, on Key Equivalent to bind the snippet to a key, in this case use {

This will cause this snippet to exist everywhere in TextMate, to limit it to only working in Ruby change the Scope Selector to source.ruby, or for the Ruby on Rails people: text.html.erb.rails, source.ruby.rails, source.ruby.rails.embedded.html, meta.rails.helper, meta.rails.unit_test, meta.rails.controller, meta.rails.functional_test, text.haml, source.ruby.rspec
