This repository provides Live Templates / Code Snippets for IDE's of JetBrains.
Simply put the Aurelia JavaScript.xml into the IDE's config/templates directory. On Windows with IntelliJ 2016, for example, this is:
C:\Users\marc\.IntelliJIdea2016.1\config\templates
In the default configuration, press Ctrl + J which pops up a list of all available live temlates. Select an entry and insert it at your cursor position via enter.
Alternatively, if you are familiar with the live template abbreviations, you can type it at the position for the live template and press tab (skip the dashes of the abbreviation when typing).
