Recursive snippet-editing

[joaotavora]

It would be really nice to have yasnippet work recursively. That is, when
editing a snippet 'tab' would, instead of just skipping to the next
snippet, first try to see if there is a new snippet in the current field,
and if so, insert that and start a 'stacked' snippet editing process.

I dont know if it's clear what I mean, but maybe this use case explains it
better:

There's two snippets:
'if' inserts a regular 'if' statement
'testx' insert 'test_for_x()'

ideally, when I want to insert the code
if (test_for_x()) {
// do something
}

I would type 'if', press tab (inserts the 'if' snippet'), type 'testx',
press tab (would insert the 'x' snippet!), and press tab again would jump
inside the curly braces of the if, exiting the snippet.

Obviously, this is an enhancement, however the google interface won't allow me to
change the type...

It will be great if this feature is supported.

I think this feature is already supported. But I'm not sure it will work in all
situations, so I just disabled it by default. If you want to try it, just add this
after YASnippet initialization:

(define-key yas/keymap [tab] 'yas/expand)

However, since Emacs can't tell the difference between TAB and [tab] on a terminal, I
think this might not work properly inside a terminal.

Another temp (and it usually works perfectly for me) is to bind expand to another key.

I bound yas/expand to C-RET, so, when i'm in snippet and i need to expand some small
snippet in it, i just press C-RET. As at expanding of snippet, C-RET sense don't
changed (as it done with TAB key), small snippet expands. Some kind of recursion.

I confirm that the recursive snippet-editing works great. Thanks.

I use hippie-expand and bind it to tab:

(setq hippie-expand-try-functions-list
(cons 'yas/hippie-try-expand hippie-expand-try-functions-list)))

And I use Enter/M-Enter to switch field:

;; reset yas/keymap
(setq yas/keymap (make-sparse-keymap))
(define-key yas/keymap (kbd "RET") 'yas/next-field-group)
(define-key yas/keymap (kbd "M-RET") 'yas/prev-field-group)

Already supported.

Also in new version 0.6.0, see also new customization variable `yas/triggers-in-field'.
