Let's say that I have the following snippet in Emacs:

# -*- mode: snippet -*-
# name: frac
# key: frac
# --
\frac{${1:numerator}}{${2:denominator}}$0

My problem is that when I write a snippet inside this snippet and press tab then the snippet is not expanding but the cursor is moving to the next placeholder.

How can I make it to first expand the snippet and then, with the next tab ro move, to the next placeholder?

  • Could you perhaps show also the second snippet inside the first?

  • @Drew There is not one specifically. Also the one I wrote is just an example. Every time I write a snippet and I want to nest one more then the tab moves the cursor without expanding first the second snippet.

From This SO answer, we see that:

yas-triggers-in-field is a variable defined in yasnippet.el.

Its value is t

Original value was nil

Documentation:

If non-nil, allow stacked expansions (snippets inside snippets).

Otherwise yas-next-field-or-maybe-expand just moves on to the next field

You can customize this variable.

So the solution to allow nested templates is:

(setq yas-triggers-in-field t)
