* 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off minor mode in some buffers, it was out of date, and not frequently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.
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.
* 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.
* 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--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.
