* 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-not-string-or-comment-condition): New constant,
holding the previous default value of `yas-buffer-local-condition'.
(yas-buffer-local-condition): Make into defcustom.
* yasnippet.el (yas--check-commit-snippet): Use
`yas-after-exit-snippet-hook' value of last exited snippet.
* yasnippet.el (yas--safely-run-hook): Also accept a list of functions.
* yasnippet.el (yas--safely-call-fun): New function, extracted from yas--safely-run-hook.
* yasnippet.el (yas--eval-for-string, yas--safely-run-hook: Let-bind
`debug-on-error' according to `yas-good-grace' and add `debug' to
condition handler to deduplicate evaluation.
* yasnippet.el (yas--eval-for-string): Don't catch yas--exception.
(yas-throw): Signal `yas-exception', not `yas--exception'; DATA must be
a list.
(yas-exception): Add `error-message' property.
(yas-verify-value): Just use plain format since the new `error-message'
property for `yas-exception' will add the right prefix.
* yasnippet.el (yas-good-grace): Add support for `inline' and `hooks' options.
(yas--eval-for-string): Renamed from `yas--eval-lisp'. Errors are
passed straight through (no rethrow) when `yas-good-grace' is nil.
(yas--handle-error): Removed.
(yas--eval-for-effect): Renamed from `yas--eval-lisp-no-saves'. Use
`yas--safely-run-hook'.
(yas-define-snippets): Update docstring.
(yas-throw): Don't throw, just signal.
(yas--save-backquotes, yas--apply-transform): Use
`yas--eval-for-string'.
(yas--safely-run-hook): Renamed from `yas--safely-run-hooks'. Takes 1
hook function, instead of a hook var; check `yas-good-grace'.
(yas-expand-snippet): Use `yas--eval-for-effect'.
* yasnippet.el (yas-snippet-mode-buffer-p): New function, detects
buffers visiting files under `yas-snippet-dirs'. Add it
`magic-fallback-mode-alist' to enable `snippet-mode' automatically,.
* 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--on-buffer-kill): New function, add to `kill-buffer-hook'.
(yas--maybe-move-to-active-field): 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--snippet): New field, expand-env.
(yas--letenv): New macro, evaluate body with a given environment.
(yas--find-next-field, yas--safely-run-hooks):
(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.
* yasnippet.el (yas--snippets-at-point): Restore as obsolete alias of
yas-active-snippets.
Close#754.
* 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.
It is obsolete as of 24.3, and this particular use of flet in this place
isn't much use anyway.
* doc/yas-doc-helper.el (yas--document-symbol): Stop using flet.
Fixes#752
* CONTRIBUTING.md:
* NEWS:
* README.mdown:
* doc/index.org:
* doc/nav-menu.html.inc:
* yasnippet.el: Since the new repo destination is now under
`joaotavora', fix all the stale links to point to the new destination.
Copyright-paperwork-exempt: yes
`buffer-file-name' is a permanent buffer-local variable, so if we reuse
the "*new snippet*" buffer, we could end up visiting the last new
snippet's file.
* yasnippet.el (yas-load-snippet-buffer-and-close): Rename the "*new
snippet*" buffer when making it visit a file.
* .travis.yml (install): Set warnings to (not cl-functions) if cl-lib
needs to be downloaded. Since the downloaded cl-lib just aliases cl.el
functions, trying to use cl- prefixed functions would cause compile
warnings otherwise.
* Rakefile: Pass environment variable `warnings' as
`byte-compile-warnings' value when compiling.
* yasnippet.el: Replace calls to cl functions with cl- prefixed cl-lib
equivalents. Use #' to quote function symbols.
(yas-snippet-dirs, yas-new-snippet-default, yas-prompt-functions):
(yas-indent-line, yas-also-auto-indent-first-line):
(yas-snippet-revival, yas-triggers-in-field):
(yas-fallback-behavior, yas-choose-keys-first, yas-choose-tables-first):
(yas-use-menu, yas-trigger-symbol, yas-wrap-around-region):
(yas-good-grace, yas-visit-from-menu, yas-expand-only-for-last-commands):
(yas-field-highlight-face, yas--field-debug-face): Remove redundant
:group.
(yas-snippet-dirs, yas-global-mode): Remove :require. The :set value
for yas-snippet-dirs checks if yas-reload-all is fbound, and the
autoload cookie on yas-global-mode makes :require redundant.
These symbols were overlooked in backporting because they're not bound
or fbound.
* yasnippet.el (yas--define-menu-1): Rewrite with `cl-loop', and support
yas/ prefixed symbols.
The yas--message function was comparing with `>' instead of `>=', which
meant it was quieter than intended (i.e., level 3 message were being
suppressed by defualt). Also push the "Snippet %d exited" message up to
level 4, so the net effect should actually be quieter than before for
normal usage (the only level 3 messages are now for loading and saving
snippets).
* yasnippet.el (yas--message): Fix off-by-1 error.
(yas--load-snippet-dirs): Lowest yas--message level should be 1, not 0.
(yas--commit-snippet): "Snippet %d exited" is more of a debug message,
put it at level 4.
Two significant changes:
1. The criteria for offering to save in upon
`yas-load-snippet-buffer-and-close' is much simplified, and relies
on `buffer-modified-p' solely.
2. C-x C-s snippet after `yas-new-snippet' or `yas-visit-snippet'
suggests at least a sensible directory.
Still missing in this commit is the suggestion for loading upon
saving. The `after-save-hook' could be used for something like that.
* yasnippet.el (yas-new-snippet): Set `default-directory' based on
result of `yas--guess-snippet-directories'.
(yas-load-snippet-buffer): Return template object.
(yas-load-snippet-buffer-and-close): Simplify.
(yas--visit-snippet-file-1): Also set `default-directory' here.
(yas--guess-snippet-directories-1): Return directory names, i.e., ending
in slash.
Most of these are minor issues involving, e.g., quoting `like this'
instead of 'like this'. A few involve escaping ` and ' with a
preceding \= when the characters should not be turned into curved single
quotes.
* 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.
