How can I setup tab size in Sublime text 2 for each file type?

Question

For example, in *.asm files I need a tab size that equals 20 spaces, and in *.cpp files - 2 spaces.

Answer 1

Open a .asm file in Sublime Text.

Then edit syntax specific settings with menu Preferences -> Settings - More -> Syntax Specific - User:

{
    "tab_size": 20
}

You can do the same with any other file type.
