Question

I want to insert a specific yasnippet as part of a function in emacs-lisp. Is there a way to do that?

The only command that seems related is yas/insert-snippet, but it simply opens a popup with all the options and the documentation doesn’t say anything about bypassing the popup by specifing the snippet name.

yas/insert-snippet is indeed just a thin wrapper around yas/expand-snippet for interactive use. However, the internal structures are… interesting. Judging from the source code the following does work for me when I want to expand the “defun” snippet in elisp-mode:

(yas/expand-snippet
  (yas/template-content (cdar (mapcan #'(lambda (table)
                                          (yas/fetch table "defun"))
                                      (yas/get-snippet-tables)))))
