Set default syntax to different filetype in Sublime Text 2

Question

How do I set a default filetype for a certain file extension in Sublime Text 2? Specifically I want to have *.cfg files default to having Ini syntax highlighting but I cannot seem to figure out how I could create this custom setting.

Answer 1

In the current version of Sublime Text 2 (Build: 2139), you can set the syntax for all files of a certain file extension using an option in the menu bar. Open a file with the extension you want to set a default for and navigate through the following menus: View -> Syntax -> Open all with current extension as... ->[your syntax choice].

Updated 2012-06-28: Recent builds of Sublime Text 2 (at least since Build 2181) have allowed the syntax to be set by clicking the current syntax type in the lower right corner of the window. This will open the syntax selection menu with the option to Open all with current extension as... at the top of the menu.

Updated 2016-04-19: As of now, this also works for Sublime Text 3.

Answer 2

Go to a Packages/User, create (or edit) a .sublime-settings file named after the Syntax where you want to add the extensions, Ini.sublime-settings in your case, then write there something like this:

{     "extensions":["cfg"] } 

And then restart Sublime Text
