MacOS – Sublime Text 2 – Save Dialogue Tab Issues

I'm afraid not, which is a shame.

I think your best bet would be to use a program like TextExpander ($35, trial available).

You can use that to define 'variables' (called 'snippets' by TE, which means something entirely different in InDesign...) like this:
You type c1 and it automatically changes to Name Of Client 1 (you'd fill in the actual name).

You can also automatically fetch things like date last modified by setting up a 'snippet' that runs a shell script or AppleScript.
Such a snippet could work like this: You type doc1mod and it would run a script you write (I can help you with that part if you want) that will find the date last modified for a document and replace doc1mod with that date.

This isn't as powerful or convenient as InDesign text variables, but the end result should come close. TextExpander isn't cheap, but I've found it worth the investment.

This worked for me.

Update ~/Library/Application\ Support/Sublime\ Text\ 2/Packages/Ruby/Ruby.sublime-build

{
  "env":{
      "PATH":"${HOME}/.rvm/bin:${PATH}"
  },
  "cmd": ["rvm-auto-ruby", "$file"],
  "file_regex": "^(...*?):([0-9]*):?([0-9]*)",
  "selector": "source.ruby"
}

The env part will add rvm-auto-ruby into the $PATH and the cmd will execute rvm-auto-ruby yourfile.rb when you press Cmd-B. You and add options in between rvm-auto-ruby if you want, like this `”cmd”: [“rvm-auto-ruby”, “-S”, “$file”].
