Apple - TextMate 2: How to permanently default to soft tabs (spaces instead of tabs)?
TextMate 2 uses a special file called .tm_properties
to control lots of settings in the app. It will use ~/.tm_properties
if present for global defaults. You can also add one inside a source tree to control settings for a particular project.
The setting you're looking for is:
softTabs = true
Just add that line to ~/.tm_properties
(or create it if it doesn't exist).
You can read more about this file here.
Put the following in ~/.tm_properties
:
softWrap = true
tabSize = 4
softTabs = true
