I want to use ES6 template string literals e.g.:

`string text line 1
 string text line 2
 string text ${expression}`

However emacs doesn't recognize that their contents are a string, so syntax highlighting, indentation, etc. don't work. How can I tell emacs that backticks are string delimiters?

I'm using emacs version 24.5, and the built in js-mode.

  • What's your Emacs version and which JS major mode are you using?

  • @lunaryorn I edited to add the information, but tbh I only opened this question as a google-friendly way to provide the answer for other people. My answer below works for me, but stack overflow won't let me accept it yet. Hope I didn't waste your time!

You need to add backticks as a string delimiter to the js-mode syntax table like this:

(modify-syntax-entry ?` "\"" js-mode-syntax-table)

For the record, ES6 template string literals are supported out-of-the-box in js2-mode, complete with font-locking for the interpolated variables as well.

Or you just wait for Emacs 25.1 to come out. It's fixed there.
