Super Snippet

This is Super Snippet, a plugin for Sublime Text 2 that gives you an extended snippet syntax. In particular in addition to the standard syntax you get:

  • Ability to use ${! ... !} to embed python code in your snippets
  • Ability to use ${` ... `} to embed shell commands

Note that these chain, so that each expansion can create syntax for the following expansion. In order the expansions go:

  • Embedded python code is evaluated and replaced with the output
  • Embedded shell commands are evalued and replaced with the output
  • Standard Sublime Text 2 snippet expansion occurs

Usage

To use type the exact name of the snippet and hit tab. If no match is found then Sublime Text 2 will execute insert_best_completion as usual (meaning that the normal tab completion will occur.)

Creating Snippets

To add new snippets you have two choices.

** Using the Settings File **

This methods is ideal for short snippets.

Create a SuperSnippet.sublime-settings file in your Packages/User directory. The format of this file is a simple JSON object where the keys are the short text to expand and the values are templates for the expansion.

In other words, on Mac OS X create ~/Library/Application Support/Sublime Text 2/Packages/User/SuperSnippet.sublime-settings that looks something like this:

{
    "uuid": "Our chosen unique string for now is: ${`uuidgen`}",
    "cc": "Character Count: ${! self.view.size() !}",
}

** Using an Individual File for Snippets **

This is more suited to longer snippets.

Create a whatever.sublime-supersnippet file in your Packages/User directory for each snippet you want to expand, using whatever snippet you want to expand instead of whatever. The file should contain the bare snippet template for expansion

In other words, on Mac OS X create ~/Library/Application Support/Sublime Text 2/Packages/User/thanks.sublime-supersnippet that looks something like this:

Dear ${0:Granny},

Thank you for the birthday gift.

All My Love

${! os.environ['LOGNAME'] !}

Please note, for security and sanity that this will only work for snippets that match the regular expression ^[A-Za-z_-]$
