Problem setting binding -- mode-map does not (yet?) exist
Jim Burton
"latex-mode-map" does not (yet?) exist.
Jim Burton
posted it for me.]
I've got a problem with this snippet, intended for latex-mode:
# -*- mode: snippet -*-
# name: set
# key: set
# binding: "C-?"
# --
\{ `yas/selected-text`$1 \\}$0
The "name" part works OK, so I can expand "set" in latex-mode, but not
the binding. Here's what I get in *Messages* after loading with C-c C-
c in snippet-mode or yas/reload-all:
[yas] warning: keybinding "C-?" invalid for snippet "set" since keymap
"latex-mode-map" does not (yet?) exist.
How come? Thanks,
Jim

mode-map. This is annoying because the mode is called latex-mode, not
LaTeX-mode and I am guessing you derive the name of the keymap from
the path? Defining latex-mode-map fixes it:
(setq latex-mode-map LaTeX-mode-map)

This only works if it is evaluated after the keymap is defined and
before yas is loaded, but it seems the keymap isn't defined until you
visit a tex file? The only way I can get the keybinding set when I
open a tex file is to add
(setq latex-mode-map LaTeX-mode-map)
(yas/reload-all)
to my LaTeX-mode-hook. I presume there is a better way to do it?

It seems you may be right about the case issue. The setq fix, though
it is close, is not what you want, I think. Try
(defvaralias latex-mode-map LaTeX-mode-map)
And report back here. I'll look into the problem as soon as I can.
Bye!

the name of the keymap but the way yas adds bindings to keymaps --
should it not do so by adding a define-key to the _hook_ for each
mode?

Errr, yes, more or less, it's complicated, but anyway in the trunk and
upcoming 0.7 this problem no longer exists, as a variable called
emulation-mode-maps-alist is used, which simplifies the whole issue
and correctly insulates the mode's maps of all yasnippet interference.
I suspect you're using 0.6something, so I encourage you to try out the trunk:
try svn co http://yasnippet.googlecode.com/svn/trunk yasnippet.
and experiment heavily with keybindings since that's one of the most
underused features. Notice that in the new version, multiple snippets,
even across different modes, can share the same keybinding.
Bye!

Yes, I'm using 0.6.1c.

Will do. Thanks,

I get no yas menu and none of the snippets aredefined. I have added
the defvaralias to LaTeX-mode-hook, and get this in *Messages*:
[...]

Removing the defvaralias has no effect.

with some instabilities. :-) can you reproduce this with a clean
emacs -Q run?
like "emacs -Q -l yasnippet.el -l simpleinit.el"
where simpleinit.el would just contain
(setq yas/snippet-dirs <dir-or-list-of-dirs>)
(yas/reload-all)
If it doesn't happen, then its a problem with your previous config. It
if still happens, post a zip of your latex snippets here, or better
yet, all your snippet dirs, as long as they're relatively small.
PS: I don't think the defvaralias matters anymore. It was just a
workaround for 0.6.1, did you try it?
Thanks!

This loads without any errors (*Messages* contains the warnings from
before but no errors). I can see two problems though: there are no
submenus beneath text-mode, just a long list with every snippet
listed, and although I can select a snippet from the menu, neither tab-
expansion or bindings work. I'm using Gnu Emacs 23.0.91.1.

Yes I did, and 0.6.1c is working fine for me with that, so I'm quite
happy to stick to that version for now.

If you used your own snippet collection please post it here so I can debug this problem.

snippet file in amongst them, a lisp file generated by AUCTeX (I think
I accidentally compiled one of the snippet files somehow). Removing
this file fixed the problem.
Thanks for your help.

correctly with your AUCTeX snippets, together with the bundled
snippets.
It's strange about that file, but I'm glad it works. From the
behaviour you described earlier (big list of snippets under
text-mode), I would have guessed you tried to use the 0.6 snippet
collection with 0.7, which is incompatible and would produce just
that, since the hierarchy organization has been completely replaced by
the used of ".yas-parents".
So have fun and report any strange behaviour here,
João
