* 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.
* 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`.
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.
* 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.
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.
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--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.
* 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.
Suggested by OGAWA Hirofumi in

* doc/snippet-development.org (Choosing fields value from a list
and other tricks): Add mention of yas-auto-next.
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.
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 (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.
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--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.

undo-indentation-multiline.
(undo-indentation-multiline-2): New test.
* 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.
