Sometimes you might want to expand a snippet directly from your own
elisp code. You should call [[sym:yas-expand-snippet][=yas-expand-snippet=]] instead of
[[sym:yas-expand][=yas-expand=]] in this case.
[[sym:yas-expand][=yas-expand=]] in this case. [[sym:yas-expand-snippet][=yas-expand-snippet=]] takes a string in
snippet template syntax, if you want to expand an existing snippet you
can use [[sym:yas-lookup-snippet][=yas-lookup-snippet=]] to find its contents by name.
As with expanding from the menubar, the condition system and multiple
candidates doesn't affect expansion. In fact, expanding from the
YASnippet menu has the same effect of evaluating the follow code:
candidates doesn't affect expansion (the condition system does affect
[[sym:yas-lookup-snippet][=yas-lookup-snippet=]] though). In fact, expanding from the YASnippet
menu has the same effect of evaluating the follow code:
#+BEGIN_SRC emacs-lisp
(yas-expand-snippet template)
#+END_SRC
See the internal documentation on [[sym:yas-expand-snippet][=yas-expand-snippet=]] for more
information.
