Warning Couldn't find space

[dericbytes]

I get 'Warning Couldn't find space' when expanding yas snippets in org src blocks.

I opened an issue in 2019 #976 and it eased the problem. However it never solved it. At the time I tried it on a fresh system but could not reproduce it. I assumed it was due to my complex setup.

I have managed to replicate it on a clean build. I stripped away as much as I could.

GNU Emacs 30.0.50 (build 1, x86_64-pc-linux-gnu, X toolkit, cairo version 1.18.0, Xaw3d scroll bars) of 2024-04-03
yasnippet 2024 - Version: 0.14.1

rm -rf ~/tmp/yas-test
mkdir !$
emacs --quick --init-directory=!$ !$/test.org

M-x package-install yasnippet
M-x yas-new-snippet

# key: di
# name: di
# --
 ($1)
  "$0"

save as emacs lisp snippet

C-c C-c
> emacs-lisp-mode
> RET
> y

Get emacs-lisp snippets to work in org-mode

M-x find-file snippets/org-mode/.yas-parents

add the text

emacs-lisp-mode

and save file.

In test.org add the code below, note there is an indent of a space before the #'s

 #+name: test
 #+begin_src emacs-lisp
      2
    di
  #+end_src

M-x yas-minor-mode
M-x yas-reload-all

place cursor after

di

and press TAB

⛔ Warning (yasnippet): Couldn’t find: "[[:space:]
]*\"[[:space:]
]*\\(\\)[[:space:]
]*\""

NOTE:

A collection of things had to be in place to generate this. Works when:

• org source block has no indent i.e. remove space before ' #+'
• the source block has no property i.e #+name
• the expansion trigger is the only thing in the source block
• the expansion trigger is after contents but still on the first line
• there is only one snippet variable
• all the snippet variables are on same line
• the quotes around $0 are removed
• the parenthesis around $1 are removed

It does not work when content is above the yas trigger.
i.e. 2 is above the 'di' yas trigger key
