* yasnippet.el (yas--get-indent-undo-pos): Renamed from
yas--return-first-indent-undo.
(yas-expand-snippet): Bind it to line beginning of snippet expansion
position.
* yasnippet-tests.el (undo-indentation, undo-indentation-multiline):
New tests for this and previous fix.
* yasnippet-tests.el (auto-fill-with-multiparagraph): New test.
* yasnippet.el (yas--auto-fill): Don't snapshot markers outside of
current paragraph.
(yas--goto-saved-location, yas--snapshot-marker-location): Count
newlines as whitespace (even if mode marks them as non-whitespace
syntax, e.g., comment end).
(yas--snapshot-overlay-location, yas--restore-overlay-location): Don't
snapshot overlay position which is outside of BEG .. END.
* yasnippet.el (yas--place-overlays): Don't move active field overlays
unless we're working on the innermost snippet.
(yas--move-to-field): Keep `yas--active-field-overlay's `yas--snippet'
property in sync with its `yas--field' property.
* yasnippet-tests.el (nested-snippet-expansion-1): Rename from
nested-snippet-expansion-1.
(nested-snippet-expansion-2, nested-snippet-expansion-3): New tests.
* yasnippet.el (yas-expand-snippet): Use the snippet's bindings when
moving to the first field. This prevents getting an error when using
a variable defined in expand-env.
* yasnippet-tests.el (snippet-mirror-bindings): New test, check if
mirror transformations have access to variables defined in the snippet
environment.
* yasnippet.el (yas--eval-for-effect): Use `yas--safely-call-fun'
instead of `yas--safely-run-hook'.
(yas--safely-call-fun): Display the called argument (even a lambda) on
errors.
(yas--safely-run-hook): Take a hook variable instead of the hook value
itself. Use `run-hooks' to take buffer-local values into account.
This means it’s no longer possible to warn which hook function had an
error.
(yas--check-commit-snippet): Refactor to conform to
`yas--safely-run-hooks'.
* yasnippet-tests.el (snippet-exit-hooks-bindings): New test that
checks for buffer-local, global and env hooks support.
* yasnippet.el (yas--update-mirrors): Delay indentation until all
mirrors are updated.
(yas--mirror-update-display): Don't indent here.
* yasnippet-tests.el (single-line-multi-mirror-indentation-2): New test.
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.
* yasnippet-tests.el (yas-org-native-tab-in-source-block): New test.
* yasnippet.el (yas--snippets-to-move): New variable.
(yas--prepare-snippets-for-move, yas--finish-moving-snippets): New
function.

(yas--snippet-revive): Use it.
(yas--snapshot-marker-location): Change format of location info.
(yas--goto-saved-location): New function.
(yas--restore-marker-location): Use it.
(yas--snapshot-overlay-location): New function.
(yas--restore-overlay-location): Use it.
(yas--post-command-handler): Call `yas--finish-moving-snippets'.
Instead of making yas-expand and yas-expand-from-keymap search for the
command that would have been called, use a conditional keybinding so the
Emacs' builtin keybinding lookup code will do the searching instead.
* doc/faq.org: Remove section about old method binding method. Update
example to use new method.
* doc/snippet-expansion.org (Trigger key): Update explanation for new
method.
* yasnippet.el (yas-fallback-behavior): Mark obsolete.
(yas--maybe-expand-key-filter): New function.
(yas-maybe-expand): New conditional binding.
(yas-minor-mode-map): Bind it to TAB and <tab>.
(yas--maybe-expand-from-keymap-filter): New function, extracted from
`yas-expand-from-keymap'.
(yas-maybe-expand-from-keymap): New conditional binding.
* yasnippet-tests.el (yas--key-binding): New function, like
`key-binding' but overrides `this-command-keys-vector'.
(snippet-load-uuid): Use it.
(test-yas-tab-binding, test-yas-in-org): Insert snippet key before
testing binding.
* yasnippet-tests.el (yas-with-even-more-interesting-snippet-dirs): Add
debug declaration.
(yas--collect-menu-items): New function.
(test-yas-define-menu): Use it to become keymap format agnostic.
* yasnippet.el (yas--delete-from-keymap): This function deletes entries
created by `yas--update-template-menu', which are always list elements.
Skip other types of keymap elements.
(yas--define-menu-1): Create a keymap with a vector element instead of a
list with gensym symbol binding list.
* yasnippet.el (yas--snapshot-marker-location): New function, save a
regexp and whitespace count determining a marker's location in a line.
(yas--restore-marker-location): New function, restores a marker's
location based on info from `yas--snapshot-marker-location'.
(yas--indent-region): Use them to fix marker locations after indentation.
* yasnippet-tests.el (indent-org-property, indent-cc-mode):
(indent-snippet-mode): New tests.
* yasnippet.el (yas-active-snippets): Rename from
yas--snippets-at-point, adjust callers. Handle arbitrary positions and
ranges as a parameter.
* yasnippet-tests.el (nested-snippet-expansion): New test.
* yasnippet.el (yas--find-next-field): For negative N, actually give the
Nth previous field, not the 1st field.
* yasnippet-tests.el (field-navigation): Add a 3rd field, and test
calling `yas-prev-field' while on it.
Fixes#722.
This changes the strategy for fixing #712 to a simpler alternative,
which doesn't remove the benefits of indenting single line mirrors.
It reverts the functional parts of commit
351c1e3dcbb73e3154aae0755d5b7016f1561ebc, while keeping the tests.
* yasnippet.el (yas--update-mirrors): Sort mirrors to be updated by
start position.
* yasnippet.el (yas--mirror-update-display): Don't indent the first line
of mirror output (meaning no indentation happens if there is a single
line).
* yasnippet-tests.el (single-line-multi-mirror-indentation): New test.
(snippet-with-multiline-mirrors-issue-665): Renamed from
navigate-a-snippet-with-multiline-mirrors-issue-665, test for precise
indentation in addition to navigation (this was already implemented,
contrary to its obsolete docstring).
Fixes#712
* yasnippet-tests.el (complicated-yas-key-syntaxes): Avoid looking-back.
* yasnippet.el (yas--font-lock-keywords): Escape $, even if first in the
regexp.
(yas--indent): Remove unused var `end'.
(yas--indent-parse-create): Remove unused arg `snippet'. Update caller.
* doc/snippet-development.org: New "Indentation markers" section.
* yasnippet-tests.el (indentation-markers): New test.
* yasnippet.el (yas--indent-markers): New variable.
(yas--indent): Use it instead of searching for $> directly.
(yas--indent-parse-create): New function, records occurences of $> into
`yas--indent-markers'.
(yas--snippet-parse-create): Call it.
* yasnippet.el (yas--indent-region): Indent only non-empty lines.
* yasnippet-tests.el (basic-indentation): Add empy and non-empty (but
blank) lines in test snippet.
cc-mode fill paragraph narrows to the paragraph being filled. This
causes problems if there is a mirror needing to be updated outside of
the current paragraph.
* yasnippet-tests.el: New test.
* yasnippet.el (yas--update-mirrors): Widen while updating the mirrors.
While I agree with the solution for #515 in commit 17fe790 for now,
other approaches might be interesting in the future, like clearing on
other types of insertion, not just self-insertion.
So add some tests and refactor a new function that could be used for
that purpose later on. For now, change no behaviour.
* yasnippet-tests.el (dont-clear-on-partial-deletion-issue-515,
dont-clear-on-yank-issue-515): New tests. (yas-mock-yank): New
function.
* yasnippet.el (yas--skip-and-clear-field-p): New function.
(yas--on-field-overlay-modification): Use it.
* yasnippet-tests.el (yas-mock-insert): Use `ert-simulate-command' to
simulate n self-insert-commands.
(simple-mirror, mirror-with-transformation):
(primary-field-transformation, nested-placeholders-kill-superfield):
(nested-placeholders-use-subfield):
(mirrors-adjacent-to-fields-with-nested-mirrors):
(deep-nested-mirroring-issue-351, example-for-issue-271):
(string-match-with-subregexp-in-mirror-transformations): Call
`yas-mock-insert' directly instead of with `ert-simulate-command'.
Probably nobody wants a snippet `key` with a trailing space. It can
be hard to differentiate from a `key` without trailing space. The
default `<TAB>` behavior of yasnippet will never expand these.
* yasnippet.el (yas--parse-template): Ignore trailing spaces in snippet
definitions.
* yasnippet-tests.el (deftest ignore-trailing-whitespace): New test for
new behavior.

This prevents snippets from a parent mode from overriding those of the
major-mode's (or yas--extra-modes). Snippets of ancestor modes may
still override snippets of some other ancestor modes, but hopefully this
won't cause much trouble in practice.
