* yasnippet.el (yas--load-directory-1): Add a `lexical-binding` cookie
to the compiled-snippet files, and silence warnings if it's absent from them.
(yas--letenv-f): New function extracted from `yas--letenv`.
(yas--letenv): Use it.
* yasnippet.el (yas-minor-mode): Fix docstring (issue#1210).
(yas--save-restriction-and-widen): Use workaround only for the old
Emacsen where it was needed.
(yas--snippet-create): Adjust Emacs version where CC-mode needed
a workaround.
(help-snippet-def): Remove useless use of `purecopy`.
Before this commit,
(yas--all-parents 'lisp-mode) would return:
`(lisp-mode lisp-data-mode prog-mode fundamental-mode fundamental-mode)`
which would cause duplicated entries when prompting,
if the snippet were for fundamental-mode.
* yasnippet.el (yas--flush-all-parents): New function.
(yas-reload-all): Use it.
* yasnippet.el (issue-492-and-494): Don't flush the all=parents cache any
more since `yas-reload-all` does it for us.
yas-reload-all does not undo the memoization done in yas--all-parents, which
causes the issue-492-and-494 test to fail when run after any tests that
expands yas-with-some-interesting-snippet-dirs.
With the memoization enabled, c++-mode is considered a parent of c-mode,
causing the issue-492-and-494 test to fail. With the memoization reset,
this does not occur.
(yas-define-snippets): Warn about identity conflicts.
(yas--one-simple-fom): New fun, extracted from `yas--simple-fom-create`.
(yas--simple-fom-create): Use it.
(yas--field-parse-create): Use it for ${N}.
(yas-not-string-or-comment-condition): Make it a function.
(yas--funcall-condition): Rename from `yas--funcall-condition`, change
its calling convention.
(yas--template-can-expand-p, yas--describe-pretty-table):
Adjust accordingly.
(yas--require-template-specific-condition-p): Add support for functions
in `yas-buffer-local-condition`.
* doc/snippet-expansion.org (The condition system <<condition-system>>):
Adjust example to avoid quoted code.
* yasnippet-tests.el (issue-492-and-494): Make the test a bit less picky.
(test-yas-tab-binding, test-yas-in-org): Test TAB rather than `tab`
because at the level at which we do the test, `tab` is not remapped to TAB.
* yasnippet-tests.el (yas-call-with-saving-variables): Don't `set` when
there's nothing to change.
(yas-with-overriden-buffer-list): Fix `buffer-list` override.
(loading-with-cyclic-parenthood, extra-modes-parenthood): Tweak tests
to be a bit less sensitive to details of ordering and number of
repetitions in `yas--modes-to-activate`.
* yasnippet.el (yas--all-parents): Make sure `mode` is always first in
the output, as is the case for `derived-mode-all-parents`.
(yas--modes-to-activate): Put extra modes first and not reversed, as
required by test `extra-modes-parenthood`.
This allows YASnippet to obey `derived-mode-add-parents`, which should
become the standard way to indicate "loose" relationships (such as
the fact that `js3-mode` is related to `js-mode` or for TS modes).
* yasnippet.el (yas--merge-ordered-lists, yas--all-parents): New functions.
(yas--modes-to-activate): Use them.
Since we already require Emacs≥24.4, there's not point keeping that
compatibility code.
(yas--modes-to-activate): Remove redundant `fboundp` test.
(yas-activate-extra-mode): Don't bother converting hashtable to alist
to pass to `completing-read`.
(yas-dont-activate-functions): Get rid of Emacs≤23 code.
(snippet-mode): `prog-mode` is always available.
(yas-x-prompt): `posn-at-point` is always available.
(yas--merge-and-drop-dups): `delete-consecutive-dups` is always available.
(Installation): Rename the Git install section to make it sound less
like the "normal&recommanded" way to install YAsnippet.
(Install with `package-install`): Mention GNU ELPA and GNU-devel ELPA.
(debug-ignored-errors): Remove left over code that became obsolete with
commit 175e0a3a102c22.
(yas--read-lisp): Fix code generation.
(yas-exception): Use `define-error`.
Prefer #' to quote function names.
(yas-after-exit-snippet-hook, yas-before-expand-snippet-hook)
(yas-after-reload-hook): A hook is not a function, but a symbol
containing functions. Fix doc accordingly.
(yas-define-snippets, yas-longest-key-from-whitespace)
(yas--field-parse-create): Make the doc fit within 80 columns.
(yas-skip-and-clear-or-delete-char): Fix ordering between `declare` and
`interactive`.
Now that we use `add-function`, we may as well avoid using the deprecated
`defadvice`
(cl-flet): Remove confusing `cl-flet` fallback, always provided by `cl-lib`.
(yas--snippet-parse-create, yas--commit-snippet):
Use `advice-add` i.s.o `defadvice`.
Instead of using `setq` and storing the old value in
`yas--original-auto-fill-function`, use `add-function`.
This makes it virtually impossible for a bug like #873/#919 to appear.
Remove the left-over debug code we had added to try and track down
#873/#919.
This requires bumping the dependency on Emacs≥24.4.
(yas--original-auto-fill-function, yas--watch-auto-fill-backtrace):
Delete variables.
(yas--watch-auto-fill): Delete function. Don't add it to variable watchers.
(yas--auto-fill-wrapper): Use `add-function`.
(yas-minor-mode): Use `remove-function`.
(yas--auto-fill): Adjust its calling convention for use with `:around`
in `add-function`. Remove left-over debug code.
(yas--post-command-handler): Remove left-over debug code.
Use utf-8 rather than latin-1.
Prefer #' to quote function names.
(special-mode): Remove backward compatibility code which never worked
since it uses `fundamental` which doesn't exist).
- Emacs 28 has a new mode ‘lisp-data-mode’ for Lisp data.
- A test that was temporarily broken passes again.
- The default for ‘org-adapt-indentation’ has changed.
* yasnippet.el (yas--eval-for-string): Convert error to a string,
rather than returning the error data (which can only lead to confusing
type errors later when code expecting a string gets a list).
* yasnippet-tests.el (yas-no-memory-of-bad-snippet): Adjust test, now
that snippet expansion swallows errors properly.
The pre-change-len argument passed to each element of
after-change-fucntions must reflect the length of the affected region
before the change happened.
In Yasnippet's case, the change enacted in yas--snippet-create is the
replacement of a region (which is almost always of length 0) with a
ready-to-navigate snippet template. The previous implementation
calculated the length of the affected region after that change
happened, which is wrong.
See https://github.com/joaotavora/eglot/issues/462 for a case where
this mattered.
* yasnippet.el (yas--snippet-create): Correct manual call to
after-change-functions.
* yasnippet.el (yas--snippet-create): Bind before-change-functions and
after-change-functions to nil instead of inhibit-modification-hooks to
t while expanding snippet. The latter also needlessly blocks overlay
and text property modification hooks (which we don't call ourselves
afterwards). This way we allow packages like iedit to better
co-operate with yasnippet.
* 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-tests.el (yas-escaping-close-brace): New test.
* yasnippet.el (yas--advance-end-maybe-previous-fields): New function.
(yas--commit-snippet, yas--on-field-overlay-modification)
(yas-expand-snippet): Use it, so that all active fields will be
extended properly, even in case of deeply nested snippet expansion.
* yasnippet-tests.el (nested-snippet-expansion-depth-2): New test.
* yasnippet.el (yas--auto-next): Loop again after moving to the next
field.
* yasnippet-tests.el (auto-next-field): Test for multiple
yas-auto-next uses.
* yasnippet.el (yas--expand-or-visit-from-menu)
(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.
* yasnippet.el (yas--before-change-modified-snippets): New variable.
(yas--merge-and-drop-dups): New function.
(yas--gather-active-snippets): New function.
(yas--on-field-overlay-modification): Use it.
* yasnippet.el
* yasnippet.el (yas--todo-snippet-indent): New variable.
(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)
(indent-mirrors-on-complex-update): New test and helper function.
* 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--goto-saved-line-location)
(yas--restore-overlay-line-location): New functions.
(yas--prepare-snippets-for-move, yas--finish-moving-snippets)
(yas--auto-fill, yas--indent-region): Adjust callers of previously
mentioned functions accordingly.
* yasnippet-tests.el (yas-org-native-tab-in-source-block-text):
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
stacked expansion.
(yas-next-field): Get current snippet according to
active field bounds.
* yasnippet-tests.el (nested-snippet-expansion-4): New test.
* 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
https://github.com/joaotavora/yasnippet/issues/953.
* yasnippet.el (yas--snippet-create): Call before and after change
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.
(yas--snippet-create): Add new snippet to list of active snippets.
(yas--check-commit-snippet): Consult list of active snippetes.
* yasnippet-tests.el (auto-next-field): New test.
(yas-saving-variables): Move up in the file.
* yasnippet.el (yas--auto-next): New helper.
(yas-auto-next): New user-visible snippet helper.
* doc/snippet-development.org (Choosing fields value from a list
and other tricks): Add mention of yas-auto-next.
* doc/snippet-development.org (mirror-fields): Note that all mirros
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.
If we popup a warning as soon as yas--original-auto-fill-function is
changed to nil, we'll have false positives in cases where
auto-fill-function was *also* going to be turned nil afterwards.
* yasnippet.el (yas--watch-auto-fill-backtrace): New variable, to save
backtrace into.
(yas--watch-auto-fill): Check both yas--original-auto-fill-function
and auto-fill-function, but only save the backtrace, don't popup the
debugger.
(yas--auto-fill): Also print the saved backtrace if
yas--original-auto-fill-function is nil.
(yas--post-command-handler): Print the saved backtrace if
yas--original-auto-fill-function and auto-fill-function is
yas--auto-fill, which means we're in a bad state.
* yasnippet.el (yas--watch-auto-fill): If we're called from
kill-all-local-variables, we don't need to check this, because
auto-fill-function will shortly be set to nil as well.
* yasnippet.el (yas--watch-auto-fill): New variable watcher to catch
the problem.
(yas--auto-fill): If `yas--original-auto-fill-function' is nil, print
a warning with some info instead of signaling an error.
Unless yas-also-auto-indent-first-line applies.
* yasnippet.el (yas--indent): Check that forward-line successfully
moved 1 line forward before trying to indent.
* yasnippet-tests.el (yas-indent-first-line)
(yas-indent-first-line-fixed): New tests.
* yasnippet.el (yas--indent): When `yas-indent-line' is `fixed',
instead of calling `indent-to-column' on each line directly, bind
`indent-line-function' and use `yas--indent-region'. The latter uses
some clever tricks to keep field regions from extending into the newly
created whitespace.
* doc/yas-doc-helper.el (yas--org-raw-html): Accept an ATTRS argument.
(yas--document-symbol): Render variables with <code
class='variable>... and functions with <code
class='function'>... instead of =...=. Render indented lisp
forms (recognized as lines beginning 4+ spaces followed by open paren)
with #+BEGIN_SRC elisp...#+END_SRC. Render \\{keymap} with
substitute-command-keys and #+BEGIN_EXAMPOE...#+END_EXAMPLE. Link
"Info node `(manul) Node Name'" to gnu.org manual page.
* yasnippet.el (yas-prompt-functions): Add spaces to make example lisp
form be recognized as lisp.
* doc/snippet-expansion.org:
* doc/snippet-organization.org: Fix typos.
* doc/stylesheets/manual.css: Add some simple styling. Mainly, this
sets 'max-width' for the main text, and centers it. Adjust the
background color.
* doc/nav-menu.html.inc: Adjust 'class' of top menu.
* doc/yas-doc-helper.el (yas--make-preamble): New function, used for
:html-preamble. It sets the element for the current page in the top
menu as bolded text to aid navigation.
* doc/stylesheets/styles.css: Remove, it was unused since the old rst
manual was removed.
* Rakefile: Comment to remind me how to run it.
* doc/snippet-expansion.org:
* doc/snippet-menu.org: It seems org 9.x got a bit stricter about link
formatting. Cross-file links *must* use the 'file:' prefix.
* doc/yas-doc-helper.el (yas--document-symbol): Org 9.x also got a bit
more strict about empty lines between a node and its property list.
Make sure not to put a blank line between variable nodes and the
property list.
* yasnippet.el (yas-snippet-mode-buffer-p): Instead of a string
comparison of file names to check whether the buffer file is in on of
the `yas-snippet-dirs', use the builtin `file-in-directory-p'
function.
The previous changed failed to account for command snippets which have
lists for bodies, not strings.
* yasnippet.el (yas-expand-snippet): Don't error if SNIPPET is a list
representing a command snippet body.
* yasnippet-tests.el (yas-expand-command-snippet): New test.
This allows proper handling of a snippet's expand-env field when doing
(yas-expand-snippet (yas-lookup-snippet NAME))
* yasnippet.el (yas-expand-snippet): Return the yas--template struct
instead of snippet body.
(yas-expand-snippet): Let first argument be a yas--template struct.
* yasnippet-tests.el (snippet-lookup, snippet-load-uuid): Update tests
accordingly.
(yas-lookup-snippet-with-env): New test.
* yasnippet.el (yas--backquote-markers-and-strings): Remove.
(yas--save-backquotes): Return list of backquote expressions.
(yas--restore-backquotes): Receive it as a parameter.
(yas--snippet-parse-create): Keep it in a local variable.
* yasnippet-tests.el (yas-no-memory-of-bad-snippet): New test.
Rather than embedding the conditionality inside the function body, and
hardcoding fallback to `delete-char'. This allows users who want, for
example, to use backspace for field skipping to simply do
(define-key yas-minor-mode-map (kbd "DEL")
yas-maybe-skip-and-clear-field)
* yasnippet.el (yas-skip-and-clear-field, yas-current-field)
(yas--maybe-clear-field-filter): New command and function, extracted
from yas-skip-and-clear-or-delete-char.
(yas-skip-and-clear-or-delete-char): Mark obsolete.
(yas-maybe-skip-and-clear-field): New constant, for conditional
binding.
(yas-keymap): Bind it to `C-d' instead of
`yas-skip-and-clear-or-delete-char'.
* yasnippet-tests.el (delete-numberless-inner-snippet-issue-562): Use
`yas-skip-and-clear-field' instead of
`yas-skip-and-clear-or-delete-char'.
* yasnippet.el (yasnippet-unload-function): New function.
* yasnippet-debug.el (yas-exterminate-package): Remove, it was only
doing a partial job of undoing modes, and uninterning is entirely not
needed.
* yasnippet-tests.el (yas-unload): New test.
During a redesign of the debug facilities, the old shortcut C-u C-t
available and useful in snippet-mode, was lost.
* yasnippet-debug.el (yas-debug-snippets): Add docstring.
Add post-command-hook locally if HOOK is snippet-navigation.
Concisely describe parent field (not just mention it).
* yasnippet.el (yas-tryout-snippet): Call yas-debug-snippets and display
buffer. Tweak docstring.
(yas-debug-snippets): Forward declare function defined in
yasnippet-debug.el
The fact that they didn't prevented a deletion of the parent field to
also delete the child, confusing snippet navigation.
* yasnippet-tests.el (delete-nested-simple-field-issue-824): Add a
test for this issue.
* yasnippet.el (yas--calculate-simple-fom-parentage): Renamed from
yas--calculate-mirrors-in-fields. Generalize to FOMs.
(yas--transform-mirror-parse-create): Call yas--simple-fom-create
and yas--calculate-simple-fom-parentage.
(yas--simple-fom-create): Rename from
yas--simple-mirror-parse-create. Call
yas--calculate-simple-fom-parentage also for fields.
On 2018-01-01 "Fix undo when first line indentation moves snippet
forward", `yas--take-care-of-redo' removed the BEG and END arguments,
but the call added to `buffer-undo-list' from `yas--snippet-revive',
was not updated accordingly.
* yasnippet.el (yas--snippet-revive): Remove `beg' and `end' from
`yas--take-care-of-redo' entry.
* yasnippet-tests.el (undo-redo): New test.
* yasnippet.el (yas-expand-snippet): Only use the `to-delete' text if
`region-active-p' return true.
* yasnippet-tests.el (expand-with-unused-yas-selected-text): New test.
* snippets:
* yasmate: Remove.
* README.mdown: Suggest yasnippet-snippets and yasmate as possible
things to download rather than submodules.
* yasnippet.el (yas-installed-snippets-dirn): Mark obsolete.
(yas-snippet-dirs): Remove `yas-installed-snippets-dir' from
default value.
* yasnippet-tests.el (yas-test-expand-and-undo): New helper function.
(undo-indentation-1, undo-indentation-2, undo-indentation-multiline-1)
(undo-indentation-multiline-2): Use it.
* yasnippet.el (yas--first-indent-undo, yas--get-indent-undo-pos):
Remove.
(yas-expand-snippet): Move undo-related code from here...
(yas--snippet-create): ... to here. Collect undo information from
yas--indent in the normal, unsuppressed way.
(yas--indent-region): Don't collect undo information specially.
(yas--take-care-of-redo): Remove unused parameters.
* yasnippet-tests.el (undo-indentation-1): Rename from
undo-indentation.
(undo-indentation-2): New test.
(undo-indentation-multiline-1): Rename from
undo-indentation-multiline.
(undo-indentation-multiline-2): New test.
* yasnippet.el (yas-expand-snippet): Since the actual insertion must
happen with modification hooks inhibited, we can't rely on that
mechanism to clear the field. Call yas--skip-and-clear-field-p on the
active field.
* yasnippet.el (yas-new-snippet-buffer-name): New constant, holds the
name of new snippet buffers. Change it to "+new-snippet+" to avoid
the leading "*" from fooling whitespace-global-mode into thinking it
shouldn't activate.
(yas-new-snippet):
* yasnippet-tests.el (snippet-save): Use the constant instead of
hardcoding the literal string.
* yasnippet.el (yas-also-auto-indent-first-line): New option.
(yas--indent-region): Also indent empty lines if it's set.
* yasnippet-tests.el (yas-also-indent-empty-lines): New test.
* Rakefile (.elc): Set byte-compile-force-lexical-warnings when
compiling.
(:compile_all): New target that compiles yasnippet-debug.el and
yasnippet-tests.el too.
* .travis.yml (script): Use it instead of `compile'. Update cl-lib to
0.6.1. Don't error on warnings for Emacs 24.3 on yasnippet-tests.el.
* yasnippet-debug.el: Don't use `yas--loaddir' if it's not
bound (e.g., when compiling). Require `color' and `edebug' at
toplevel. Check if `subr-x' defines `when-let'.
(yas-debug-snippet-vars): Remove, it was unused and broken.
* yasnippet-tests.el (yas-with-snippet-dirs, (yas-should-expand)
(yas--collect-menu-items, yas-should-not-expand, yas-mock-insert)
(yas-mock-yank, yas--key-binding, yas-make-file-or-dirs)

* yasnippet-debug.el (yas--condition-cache-timestamp): Move it before first use.
(yas-debug-live-marker, yas-debug-live-range, yas-debug-snippet-vars)
(yas-debug-process-command-line): Remove or mark unused
variable/parameters.
(yas--letenv): Use `cl-progv'.
(yas--mirror-update-display): Remove unused SNIPPET parameter, update
caller.
Avoid `yas--auto-fill' call to `yas--update-mirrors' without setting
the snippet environment.
* yasnippet.el (yas--auto-fill): Reinstate snippet environment before
calling `yas--update-mirrors'.
* NEWS: Update for 0.12 changes.

org-mode implements the "native" tab for source blocks by copying the
source block text into a temporary buffer, calling the command bound to
<tab>, and then copying back the result. To preserve snippets in this
scenario, when the temp buffer is killed we record the relative
locations of the snippet's markers and overlays and then put them into
place in the post command handler.

(yas--on-field-overlay-modification):
(yas-expand-snippet, yas--snippet-create): Use it.
While officially it was an "internal" function, there were at least 2
other packages using it.
