These aren't actual modes. Set checkdoc-symbol-words to avoid
false-positives. The first line of doc-strings of methods do
not need to end with period.
* lisp/gnus/gnus-sum.el (gnus-summary-first-unread-subject)
(gnus-summary-first-unseen-subject)
(gnus-summary-first-unseen-or-unread-subject): Use it.
(gnus-summary--goto-and-possibly-unhide): New function -- don't
unhide the first thread unless necessary (bug#51344).
* lisp/image-dired.el: Fix documentation on thumbnail file format to
correctly say that it can be either PNG or JPEG; not just JPEG. Also
fix inconsistent formatting in comments.
* lisp/image-dired.el (image-dired-thumbnail-storage): Improve
docstring.
* lisp/image-dired.el (image-dired-cmd-pngnq-program)
(image-dired-cmd-pngnq-options): Add support for pngquant.
Prefer, in this order: pngquant, pngnq-s9, pngnq-s for reasons of
speed and how actively maintained the projects seem to be.
* lib-src/ntlib.c (_GL_ATTRIBUTE_MALLOC)
(_GL_ATTRIBUTE_DEALLOC_FREE): Define to avoid compilation errors
with MinGW64 GCC 11. Suggested by Andy Moreton
<andrewjmoreton@gmail.com>. Do not merge to master.
* lisp/help.el (help-link-key-to-documentation): New user option.
(substitute-command-keys): Add a link from keys to the command they
are bound to, if the above new option is non-nil. (Bug#8951)
* etc/NEWS: Announce the new option.
* lisp/dired.el (dired-readin): Use it.
* lisp/dired.el (dired-make-directory-clickable): New user option.
* lisp/dired.el (dired--make-directory-clickable): New function
(bug#21973).
* lisp/dired-x.el (dired-x-guess-file-name-at-point): Make
obsolete in favour of 'thing-at-point'.
(dired-x-read-filename-at-point): Use 'thing-at-point' instead of
above obsolete function.
* doc/misc/cl.texi (Mapping over Sequences): Change the
explanation of 'cl-reduce' so you don't need to have a major in
mathematics to understand it. (Bug#24014)
* doc/lispref/functions.texi (Calling Functions): Improve
documentation of 'apply-partially' to be slightly more clear with
regards to function arity. (Bug#17623)
* lisp/image-dired.el (exif): Require.
(image-dired-cmd-read-exif-data-program)
(image-dired-cmd-read-exif-data-options)
(image-dired-get-exif-data): Make obsolete in favour of using
exif.el. This removes a dependency on external exiftool for some
operations.
(image-dired-get-exif-file-name)
(image-dired-thumbnail-set-image-description): Use exif.el
functions instead of exiftool.
* lisp/image/exif.el (exif-tag-alist): Add description and
copyright fields.
* test/lisp/image-dired-tests.el: New file.
* test/lisp/image/exif-tests.el (exif-elem): Move function from here...
* lisp/image/exif.el (exif-field): ...to here, and rename.
(exif-orientation):
* test/lisp/image/exif-tests.el (test-exif-parse)
(test-exif-parse-short): Use above new function.
* lisp/finder.el (finder-goto-xref): Move from here...
* lisp/emacs-lisp/package.el (package--finder-goto-xref): ...to
here. Make the old name into an obsolete function alias.
(package--finder-xref): New button type.
(package--describe-add-library-links): Factor out new function...
* lisp/finder.el (finder-commentary): ...from here.
(describe-package-1): Call above new function. This fixes an
issue where commentaries reached via 'finder-list-keywords' did
not have links. (Bug#10814)
This aims to fix the scenario where on jit-lock's first scan of a type, it is
not recognized as such, and only later does this happen. The fontification of
such found types is now done by background scanning in short time slices
immediately after initialising the mode.
* lisp/progmodes/cc-engine.el (c-add-type-1): New function.
(c-add-type): Extract c-add-type-1 from it, and reformulate the mechanism for
protecting c-found-types from excessive partial identifiers.
* lisp/progmodes/cc-fonts.el (c-font-lock-complex-decl-prepare): Remove the
code which cleared c-found-types on fontification at BOB.
(c-find-types-background): New function, based on c-font-lock-declarations).
(c-types-finder-timer-func): New function.
(c-re-redisplay-timer): New variable.
(c-force-redisplay, c-fontify-new-found-type): New functions.
* lisp/progmodes/cc-mode.el (c-type-finder-timer): New variable.
(c-leave-cc-mode-mode): Nullify c-post-command-hook and c-type-finder-timer
when the last CC Mode buffer of a session is killed.
(c-type-finder-pos): New variable.
(c-basic-common-init): Initialize c-type-finder-pos and c-type-finder-timer.
(c-new-id-start, c-new-id-end, c-new-id-is-type): New variables.
(c-update-new-id): New function.
(c-post-command): New post command hook function, used for checking moving
away from partially typed identifiers, and making them full identifiers.
(c-before-change): Add code to clear c-found-types on a buffer change at BOB.
(c-after-change): Call c-update-new-id to keep track of partially typed
identifiers.
* doc/misc/cc-mode.texi (Found Types): New @section in the @Chapter Font
Locking.
* lisp/progmodes/cc-vars.el (c-type-finder-time-slot)
(c-type-finder-repeat-time, c-type-finder-chunk-size): New customizable
options.
