Warning Couldn't find space #1197
Description
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

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
