Yasnippet snippets never exit

[tdavis]

It seems there's a bug with the yasnippet generation because snippets do not exit. Basically this means I need to call yas-exit-all-snippets after I'm done tabbing through and filling out each template or "bad things" happen (read-only text, TAB jumps back to the template regardless of point position, etc.)

I have this problem too, so much that I have bound yas-exit-all-snippts to C-]. Wonder if this has anything to do with the yas version as it cannot be that the bug has always been there.

[tdavis]

Yeah, I've had to bind it to a key as well. I poked around for a while and this really seems like an issue internal to yasnippet. I could get the most basic call to yas-expand-snippet (like, "${0}") to not close. And yet I don't notice this issue with file-based snippets, just this function.

[root42]

Yup, I know this problem as well. Any solutions?

I sometimes have weird problems with yasnippet expansion, but most of the time they work fine. What version of yasnippet are you running? I have the ELPA-installed one called yasnippet-20130505.2115.

I'm on 2013-10-14. In this version, I actually can't even get snippets with more than two fields to expand properly:

I had this issue with a few modes that use Yasnippet. (Regardless of version.)

I found out that this only happens for me when "yas-minor-mode" wasn't enabled in the buffer using some of Yasnippet's functionality.

Adding "(yas-global-mode)" to my .emacs fixed the issue permanently, but for those that don't want global Yasnippet, it would be a good idea to add "(yas-minor-mode)" to the hooks of any modes that use it.

So, something like "(add-hook 'eclim-mode-hook (lambda () (yas-minor-mode-on)))" in your .emacs should fix it for eclim.

That could very well be the problem. I tried running without yas-minor-mode activated and thus was able to replicate the problem. I've added a check to make sure that yas-minor-mode is actually active before attempting any template expansions. Thanks, @Archenoth !

Please let me know if this solves the problem, guys.
