Multiple choices in yasnippets

I’ve written before about using yasnippet as a powerful text expansion and template tool in Emacs. In its basic form you type a keyword and press TAB to expand that into a template with active fields and then use TAB to move between the fields adding your content. I recently discovered that you can programme a snippet to contain multiple choices for fields.

For example, the following snippet uses the keyword test and inserts a template with the cursor initially in the first field and prompts the user to choose from the options “high”, “average” and “below average”. Selecting your choice and then hitting TAB takes you to the next field with options of “easy” and “hard”.

# -*- mode: snippet -*-
# name: test
# key: test
# --
Importance: ${1:$$(yas-choose-value '("high" "average" "below average"))}
Difficulty: ${2:$$(yas-choose-value '("easy" "hard"))}
