Question Regarding Trying To Implement Yasnippet Templates To Wrap Source Blocks Around Regions

Question Regarding Trying To Implement Yasnippet Templates To Wrap Source Blocks Around Regions

[Samuel Banya]

Hey there,

I'm trying to figure out how to utilize a Yasnippet template to wrap a source block around a section of code that I've highlighted.

Here's the template I used in '/home/sam/hub/dotfiles/emacs/.emacs.d/snippets/org-mode':

# -*- mode: snippet -*-
# name: wrapsrc
# key: C-;
# expand-env: ((yas-wrap-around-region t))
# --
#+begin_src $1
  $0
#+end_src

Here are the links I tried referring to as references:
https://joaotavora.github.io/yasnippet/snippet-reference.html#yas-wrap-around-region

https://gist.github.com/kazu634/290872

https://stackoverflow.com/questions/9082999/how-to-insert-a-latex-environment-around-a-block-of-text-in-emacs

Any ideas on how to do this?

Thanks,

Sam

You are not telling us how exactly you tried to expand that, what you
expected and what happened instead, so I’ll venture a guess: You’re
pressing Ctrl+semicolon and it does not expand. Instead, Emacs tells
you “C-; is undefined”.

According to docs[1], you need the ‘# binding:’ (not ‘# key:’) keyword
to set the key that will expand the snippet. Alternatively, you could
type your snippet’s key (that’s capital letter C, followed by hyphen,
followed by semicolon), then press TAB, and it might expand; but I
guess that’s not what you meant to do.

Also I hope you’re doing that in a GUI frame and not in a terminal.
Not many terminals can faithfully deliver the Ctrl+semicolon
keystroke.

Hey there Yuri,

Sorry to not be complete about my previous email.

To be more specific:
- I opened up my GUI Emacs
- I made a quick Org mode buffer, and put in some example Bash lines:
dir
ls

- I then highlighted this same sets of commands, and hit 'C-;' and then hit Tab.

- When I did the above actions, I get the following shown in the Helm Mini Buffer:
'C-; is undefined'
EMPTY EMPTY

Hoping that helps a bit :)

Sincerely,

Sam
