* 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.
Since modification hooks run just after any function that changes buffer
contents, it's important to save the match data, or else the code doing
the modification can become really confused. See also Emacs bugs #23917
and #23869.
* yasnippet.el (yas--on-field-overlay-modification): Wrap main body in
`save-match-data'.
"Don't indent first line of mirrors" had the drawback that sometimes
we *want* to indent the first line of mirrors. So we fix the underlying
problem in a different way and add a test to make sure we don't lose
this behaviour again.
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.
This reverts commit e21420a497c1d79edc6b36ffb1f3bf1bb70f6227. This
breaks existing snippets which use side-effecting functions inside
backquotes to insert data instead of return the string to insert. This
usage will be deprecated, but we still need to support it for at least
another release.
* yasnippet.el (yas--save-backquotes): Go back to interleaved parsing
and evaluating of backquoted lisp forms.
* yasnippet.el (yas-describe-table-by-namehash): new function.
(yas-describe-tables): remove query for by-namehash variant, replace
query for non-active tables with prefix arg.
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.
