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.
* 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.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--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)
(yas-variables, yas-call-with-saving-variables)
(yas-call-with-snippet-dirs, special-mode, string-suffix-p): Move to
top section.

to top-level.
* yasnippet.el (yas--letenv): Evaluate the FORMs of ENV.
* 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.
* snippets/: Update to latest.
* yasnippet-debug.el:
* yasnippet-tests.el:
* yasnippet.el: Update copright years. Update version number to
0.12.0.
yasnippet-debug.el can now be used to quickly test and debug a snippet
in a file.

* yasnippet-debug.el: Set lexical binding.
(when-let): Backwards compabtility definition.
(yas-debug-live-indicators, yas-debug-live-colors)
(yas-debug-recently-live-indicators, yas-debug-get-live-indicator)
(yas-debug-live-marker, yas-debug-ov-fom-start, yas-debug-ov-fom-end)
(yas-debug-live-range, yas-debug-with-tracebuf, yas-debug-snippet)

(yas-expand-snippet): Use them to collect the exact undo info from
indenting the first snippet line, rather than trying to reconstruct
it.
(yas--indent-region): Put undo info from indenting snippet's first
line into `yas--first-indent-undo' if `yas--return-first-indent-undo'
is non-nil.

syntax, e.g., comment end).
(yas--snapshot-overlay-location, yas--restore-overlay-location): Don't
snapshot overlay position which is outside of BEG .. END.
