* yasnippet.el (yas--scan-for-field-end): New function.
(yas--field-parse-create): Use it instead of yas--scan-sexps, which
isn't able to distinguish between ${...} (a nested field) and
{...} (plain old braces in the snippet text).

* yasnippet.el (yas--advance-end-maybe-previous-fields): New function.
(yas--commit-snippet, yas--on-field-overlay-modification)

extended properly, even in case of deeply nested snippet expansion.

(yas--expand-or-prompt-for-template)
(yas-visit-snippet-file, yas-tryout-snippet): Don't pass expand-env
when to yas-expand-snippet when first arg is a yas--template record.
For deletion, we need to check the bounds before the deletion happens,
otherwise the overlay may already be moved to wrong place.

(yas--merge-and-drop-dups): New function.
(yas--gather-active-snippets): New function.
(yas--on-field-overlay-modification): Use it.
* yasnippet.el

(yas--on-field-overlay-modification): Save snippet to it, and don't
indent after mirror update.
(yas--do-todo-field-updates): New function.
(yas--post-command-handler): Call it.
(yas--snippet-field-mirrors, yas--indent-mirrors-of-snippet): New
functions, split out from...
(yas--snippet-field-mirrors): ...here.
* yasnippet-tests.el (yas-test-delete-and-insert-command)

* yasnippet.el (yas-keymap-disable-hook): New hook.
(yas-filtered-definition): New function.
(yas-keymap): Use it.
* doc/faq.org: Update key redefinition example.
Since we now check conditions in conditional keybindings, it can be
evaluated before 'this-command' has been assigned.
* yasnippet.el (yas-not-string-or-comment-condition): Remove check of
'this-command'.
There was some half-backed code getting confused between "plain"
snapshort info and line+snapshot info leading to some type errors when
expanding snippets in org-mode src blocks. I had wrongly assumed the
failures were only due to org version 9 changes (in fact, the org
changes only affect snippet expansion for text-mode (and probably
other non-fontifying modes too)). Reorganize the snapshotting
functions so that line+snaphot has the line info after the marker,
next to the rest of the snapshot info. This removes the need for list
manipulation and simplifies the code. Furthermore, let the
restoration functions take the info as a list, rather than separate
arguments, this removes the need for several uses of `apply'.
* yasnippet.el (yas--snapshot-location): Renamed from
yas--snapshot-marker-location, don't return marker.
(yas--snapshot-line-location): New function.
(yas--goto-saved-location): Take single list arg. Return point.
(yas--restore-marker-location): Remove, open code callers.

(yas--auto-fill, yas--indent-region): Adjust callers of previously
mentioned functions accordingly.

Renamed from yas-org-native-tab-in-source-block.
(yas-org-native-tab-in-source-block-emacs-lisp): New test.
(do-yas-org-native-tab-in-source-block): Take MODE parameter.
Generally, the user won't be interacting with, or creating snippets in
temporary buffers.
* yasnippet.el (yas-temp-buffer-p): New function.
(yas-dont-activate-functions): Add it to default value.
* yasnippet-tests.el (complicated-yas-key-syntaxes)
(test-yas-activate-extra-modes): Call yas-minor-mode instead of
yas-minor-mode-on, to ensure activation.
* yasnippet.el (yas--snippet-create): Let-bind
inhibit-modification-hooks for snippet insertion, so that we don't
call change functions automatically, we already call them manually
after insertion and parsing.
* yasnippet.el (yas-completing-read): New function.
(yas-verify-value): Simplify with `member' instead of `cl-notany'.
* doc/snippet-development.org (Template Syntax): Show
`yas-completing-read' instead of `yas-choose-value' in the example.
* yasnippet.el (yas--modes-to-activate): If a mode doesn't have a
`derived-mode-parent' property, use `fundamental-mode'.
* yasnippet-tests.el (loading-with-cyclic-parenthood)
(issue-492-and-494): Expect fundamental-mode to be active.
* doc/snippet-expansion.org (Eligible snippets): Mention that
fundamental-mode is a fallback parent mode.
* doc/faq.org: Add two questions about yas-key-syntaxes. Remove
reference to obsolete Google Groups. Remove question about turning
off minor mode in some buffers, it was out of date, and not frequently
asked.
* yasnippet.el (yas-key-syntaxes): Fix docstring.
* yasnippet.el (yas--on-field-overlay-modification): Call
yas--advance-end-maybe on all pending active snippets in case of

* yasnippet-debug.el (yas-debug-live-range): Consider an overlay as
live, not dead even though it has integer bounds.
(yas-debug-with-tracebuf): Add debug declaration.
Suggested by OGAWA Hirofumi in

functions around yas--snippet-parse-create.
* yasnippet-tests.el (indent-cc-mode-2): New test.
* yasnippet.el (last-buffer-undo-list): Remove, apparently it works
around some bug in "Carbon Emacs", but yasnippet is probably not the
right place for such a workaround anyway (yasnippet does not use
last-buffer-undo-list).
* yasnippet.el (yas--active-snippets): New buffer-local variable.
(yas-active-snippets): Use it, when asked for all active snippets.
(yas--commit-snippet): Remove finished snippet from list of active
snippets.

are updated when any field is changed.
(mirror-transformations): Add an example of a mirror taking values
from multiple fields.
In the README and in the FAQ, mention and link to the list of support
issues in the Github issue tracker.
Rewrite README.mdown slightly for readability and suggest the GH
tracker as primary place for YASnippet discussion.
Retire the YASnippet google group.
* README.mdown (Manual, issues, etc): Mention docs, support issues
and issue tracker separately. Remove reference to the YASnippet
google group.
(Where are the snippets?): Properly write YASnippet for
consistency.
* doc/faq.org: Add note and link to support issues.
* yasnippet.el (yas--remove-misc-free-from-undo): New function.
(yas--save-restriction-and-widen): New macro.
(yas--eval-for-string, yas--snippet-parse-create)
(yas--indent-region, yas--save-backquotes)
(yas--restore-backquotes, yas--update-mirrors): Use it.
Previously, we were unconditionally pushing entries onto the undo
list, which effectively enables undo, even in buffers where it's
disabled.
* yasnippet.el (yas--commit-snippet, yas--snippet-revive)
(yas--snippet-create): Check that `buffer-undo-list' is a list before
pushing to it.
