After the Github acocunt name change (capitaomorte -> joaotavora),
most links to repositories are redirected excpect Travis CI and
Github Pages (documentation).
* README.mdown: Fix documentation and Travis badge links
* yasnippet.el (yas-alias-to-yas/prefix-p): Rename from
yas-backport-obsolete-alias.
(yas/root-directory): Only define if yas-alias-to-yas/prefix-p is
non-nil. Mark obsolete.
The user's hooks may try to enable yas-minor-mode before yasnippet.el
has finished loading. In [1], we catch and ignore the errors arising
from this, but it's better if we can avoid hitting the error in the
first place.
This means we have 3 separate measures to avoid the problem, but since
this bug can leave Emacs unusable due to a failing post-command-hook,
a bit of redundant safety is not a bad thing.
* yasnippet.el (yas-minor-mode): Only turn on if yasnippet is fully
loaded.
(yas--font-lock-keywords): Disable user hooks.

during snippet creation. The snippet creation manipulates the
syntax-table which can lead to conflicts (see also
http://debbugs.gnu.org/cgi/bugreport.cgi?bug=23443).
* yasnippet.el (yas-expand-snippet): Let-bind syntax-propertize-function
to nil and then call syntax-ppss-flush-cache afterwards.
* yasnippet.el (yas--apply-transform): Don't let-bind yas-moving-away-p
to nil, it's nil by default.
(yas-next-field): Call `yas--field-update-display' instead of only
calling `yas--eval-lisp' so that the result of the transform is inserted
into the buffer.
yas-find-snippets was removed by [1].
* doc/snippet-development.org: Add keybindings on same line as command
names, fixup intra document links, and remove mention of non-existent
command yas-find-snippets.
* yasnippet.el (yas-load-snippet-buffer):
(yas-load-snippet-buffer-and-close): Fix docstring formatting.
[1]: "cleanup: remove `yas/find-snippets\', complicated and no one seems
to use it anyway" 29 May, 2012 433c93746534ebb062afe4dbc7690f736be72d42.
* 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.
Make sure output that occurs in normal use goes to verbosity levels 3 or
higher, and level 2 and below are reserved for something unexpected
happening. Level 3 (the new default) should be a reasonably quiet but
informative level.
* yasnippet.el (yas--read-keybinding, yas--safely-run-hooks):
(yas--on-protection-overlay-modification): Put warnings at verbosity
level 2.
(yas--load-yas-setup-file, yas-load-directory):
(yas--load-directory-1, yas--load-snippet-dirs):
(yas-expand-snippet, yas--load-pending-jits): Put per-file loading and
other debug messages at level 4.
(yas-load-snippet-buffer, yas--template-get-file, yas-reload-all): Put
top level loading messages at level 3 (or 2 if there were errors).
(yas--define-menu-1, yas-insert-snippet, yas-tryout-snippet): Put error
messages at level 1.
(yas-verbosity): Reduce default verbosity to level 3.
* doc/snippet-development.org (Template Syntax):
(Placeholder fields, Mirrors): Text inside dedicated target <<angle
brackets>> does not show up in output, so duplicate it. Add
descriptions to avoid getting numbers instead of names in links.
Htmlized output can now be produced by
rake doc[/path/to/htmlize/]
* Rakefile (doc): Add htmlize argument.
* doc/yas-doc-helper.el (yas--generate-html-batch): Tell org to use css
selectors only when exporting htmlized faces.
* doc/stylesheets/manual.css: Add styles for faces used by org export.
When inserting text due to a non-nil yas-wrap-around-region and the
snippet had fields occuring later in the buffer than $0, the insertion
of the text was shifting the location of later fields, thus invalidating
the calculation of yas--dollar-regions.
* yasnippet.el (yas--simple-mirror-parse-create): Don't insert text fo
yas-wrap-around-region here.
(yas--snippet-parse-create): Do it here, after deleting
`yas--dollar-regions`, instead.
This makes yas-expand-from-trigger-key consistent with
yas-insert-snippet.
* yasnippet.el (yas-expand-from-trigger-key): Expand start end interval
with active region.
This reverts commit f8d1af1f50f42ac1689c583c152c3b15e8774ae4.
Disabling this for trigger key introduced an inconsistency that is more
complicated to implement and document than simply fixing region wrapping
for trigger key expanded snippets.
It's too awkward to highlight the relevant text while maneuvering point
in front of the trigger key.
* yasnippet.el (yas-expand-from-trigger-key): Let-bind
yas-wrap-around-region to nil if it was t.
* doc/snippet-expansion.org: Document it.
Replace `cua' setting with more general behaviour that can use any given
register. A `cua' setting is converted to ?0 for backwards
compatibility.
* yasnippet.el (yas--simple-mirror-parse-create): Use contents of any
register depending on `yas-wrap-around-region' value.
(yas-wrap-around-region): Update docstring.
* yasnippet.el (yas--indent-region): Adapted and redesigned from
`yas--indent-according-to-mode'
(yas--indent-according-to-mode): Deleted.
(yas--indent): Use `yas--indent-region'.
(yas--real-line-beginning): Deleted.
(yas--update-mirrors): Always re-place active field overlay if it
exists. Pass the snippet to `yas--mirror-update-display'.
(yas--mirror-update-display): Indent the mirror text after
inserting the reflection.
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.
* .travis.yml: Don't use sudo, submodules.
(env): Test with additional Emacs versions.
(install): Get Emacs binaries from
https://github.com/npostavs/emacs-travis/releases. Download ert and
cl-lib if needed.
(script): Split compilation and testing into separate steps.
* Rakefile: Use batch-byte-compile. Treat compilation warnings as
errors.
In [1] we started deciding clearing based on a command's
delete-selection property, but it turns out that some commands perform
insertion, and optionally use the region's contents. So these commands
should have a nil delete-selection property, but they still ought to
clear a snippet field when used.
To achieve this, we now check if the command has inserted text in the
post-change hook of the field overlay.
* yasnippet.el (yas--skip-and-clear): Add optional FROM paramter. Only
clear non-empty fields.
(yas--skip-and-clear-field-p): Check the change start and length
instead of current command delete-selection property.
(yas--on-field-overlay-modification): Perform field clearing on the
post-change call.
[1]: acf2cdd "Decide field clearing commands based on delsel"
of protection overlay. Changes that keep the same length of text are
probably harmless (e.g. just change of text properties). It's possible
that some harmful changes don't change text length, but the protection
overlays are already unable to catch all important changes since they
only cover 1 character each at the edges.
cc-mode modifies text properties in the buffer to cache parsing results,
therefore it's important that yasnippet not kill yasnippets when parsing
is triggered by a function that only wants to parse the
buffer (e.g. which-function-mode).
* yasnippet.el (yas--on-protection-overlay-modification): Check length
of text change to decide if change is harmful. Fix docstring.
* yasnippet.el (yas-dont-activate-functions): Rename from yas-dont-activate.
(yas-minor-mode-on): Use run-hook-with-args-until-success instead of
funcall.
while describing snippet tables. This should also help users of
packages like pbcopy.el (which creates a new process on every
modification of the kill-ring, hence many `kill-region' calls at once
cause Emacs to run out of file descriptors).
* yasnippet.el (yas--create-snippet-xrefs): Use delete-region instead of kill-region.
Copyright-paperwork-exempt: yes
Close#675.
* yasnippet.el (yas--font-lock-keywords): ignore-errors from
emacs-lisp-mode call, in case user's hooks cause problems (e.g. enabling
`yas-minor-mode' before we finish loading).
* yasnippet/yasnippet.el: Add Package-Requires since we use cl-lib.
(yas-installed-snippets-dir, yas--default-user-snippets-dir)
(yas--load-directory-1, yas-load-snippet-buffer-and-close):
Use expand-file-name.
(yas-buffer-local-condition): Let's not quote lambdas.
(yas--modes-to-activate): Fix compiler warning about free `dfs' var and
unused return value of `mapcar'.
(yas-minor-mode): Don't confuse emulation-mode-map-alists for a hook.
(yas--font-lock-keywords): Don't hardcode the name of emacs-lisp-mode's
font-lock keywords.
(yas--calculate-group): Use file-relative-name.
(yas--subdirs): Don't mismatch \n in file name.
(yas-expand-from-trigger-key, yas-tryout-snippet): Prefer numbers to
number names.
(yas--guess-snippet-directories): Use expand-file-name rather than
removing&adding / by hand.
(yas--on-field-overlay-modification): Mark `length' as unused.
(yas--update-mirrors): Try to better fit within 80 columns.
(yas--backported-syms, yas--exported-syms): Don't mismatch \n in
symbol name.
* yasnippet.el (yas-new-snippet-default): Remove
"require-final-newline: nil", it's redundant since `snippet-mode' already
sets that. Also remove the direct-keybinding, since it's hardly ever
used, and often the literal "# binding: direct-keybinding" ends up in
actual snippets.
It is not a very pleasant method when there are many values, and
`yas-completing-prompt' will usually do a better job, in addition to
respecting customizations to `completing-read-function'.
`yas-dropdown-prompt' remains in first place, since it only takes effect
if the `dropdown' library is loaded, which likely indicates a preference
for it.
* yasnippet.el (yas-prompt-functions): Remove yas-x-prompt from default value.
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.
