Textmate 2: How do I set the tab size for .rb files?

Question

I have a .tm_properties file in my home folder with the following contents:

softWrap = true
tabSize = 4
softTabs = true

However, if I open an .rb file and hit tab, it will only indent 2 spaces on the new line. How can I make it 4?

Answer 1

In addition to global settings in the home folders ~/.tm_properties, there are also ./.tm_properties for file types (below) or by project ([project folder]/.tm_properties)

Find more about the settings (credit dvessel).

In short:

[ *.rb ]
  tabSize = 2
