* test/lisp/tar-mode-tests.el (tar-mode-test-tar-extract-zip-and-gz):
* test/lisp/arc-mode-tests.el (arc-mode-test-zip-extract-tar-and-gz):
New tests.
* test/data/decompress/tzg.tar.gz:
* test/data/decompress/ztg.zip:
New data files to test decompressing of different combinations
of nested tar and zip archives.
Previously, this always said "Previous" for
'previous-matching-history-element' (likewise "Next"). Now, the prompt
accounts for a negative prefix argument changing the search direction
(bug#70882).
* lisp/simple.el (previous-matching-history-element)
(next-matching-history-element): Consult numeric prefix argument to
determine the prompt string.
This also fixes an issue in EWW and bug-reference-mode where
(thing-at-point 'url) at the end of a URL would return nil.
See <https://lists.gnu.org/archive/html/emacs-devel/2024-02/msg00200.html>.
* lisp/thingatpt.el (forward-thing-provider-alist)
(bounds-of-thing-at-point-provider-alist): New variables...
(forward-thing, bounds-of-thing-at-point): ... use them.
(text-property-search-forward, text-property-search-backward)
(prop-match-beginning, prop-match-end): Declare.
(thing-at-point-for-text-property, forward-thing-for-text-property)
(bounds-of-thing-at-point-for-text-property): New functions.
* lisp/net/eww.el (eww--url-at-point): Use
'thing-at-point-for-text-property'.
(eww--bounds-of-url-at-point, eww--forward-url): New functions...
(eww-mode): ... use them.
* lisp/progmodes/bug-reference.el (bug-reference--url-at-point): Use
'thing-at-point-for-text-property'.
(bug-reference--bounds-of-url-at-point, bug-reference--forward-url): New
functions...
(bug-reference--init): ... use them.
* test/lisp/thingatpt-tests.el (thing-at-point-providers)
(forward-thing-providers, bounds-of-thing-at-point-providers): New
tests.
* etc/NEWS: Announce this change.
* src/regex-emacs.c (STORE_NUMBER): Make the arg int, not int16_t.
There’s no need for the caller to convert to int16_t, and using
int makes the machine code a bit smaller (and presumably a bit
faster) on x86-64 with GCC 14.
* src/lisp.h (hash_hash_t, knuth_hash): Use unsigned int and
unsigned long long int rather than uint32_t and uint64_t, as POSIX
does not guarantee the presence of uint64_t, and uint32_t and
uint64_t both in theory have problems with undefined behavior on
integer overflow. This doesn’t affect behavior (or even machine
code) on typical platforms.
* src/sfnt.c (sfnt_map_table, sfnt_read_table)
(sfnt_read_cvar_table): Pacify GCC -Wanalyzer-null-dereference.
The change to sfnt_read_cvar_table fixes what appears to be
an actual null-dereference bug.
When PIXELWISE is nil, we still calculate width in pixels and
then convert it to columns. However, part of the calculation
was using columns where it should have used pixels. (Bug#70894)
* config.bat: Generate stdbit.in-h from stdbit.in.h.
* msdos/sedlibmk.inp (GL_STDC_...): Enable generation
of ISO C2x features.
(STDBIT_H): Define to stdbit.h.
(GL_GENERATE_STDBIT_H_CONDITION): Define to 1.
* etc/ERC-NEWS: Mention new face `erc-information'.
* lisp/erc/erc-button.el (erc-button-add-buttons): Skip buttonization
when the "msg prop" `erc--skip' is present and contains the symbol
`button'. Set `alist' to nil in the same guard condition as a
roundabout way of suppressing further processing.
* lisp/erc/erc-networks.el (erc--insert-admin-message): Forward
declaration.
(erc-networks--insert-transplanted-content)
(erc-networks--transplant-buffer-content): Replace former with latter.
Change signature to take source and destination buffers as parameters.
(erc-networks--transplant-target-buffer-function): New function-valued
variable.
(erc-networks--target-transplant-in-progress-p): New variable, a flag
for downstream code to detect when a transplant is underway.
(erc-networks--reclaim-orphaned-target-buffers): Defer to
`erc-networks--transplant-target-buffer-function' to handle the actual
transplant business. Crucially, kill the buffer afterwards instead of
beforehand. If new buffer-association bugs emerge related to the
combining of old or renamed target buffers, this reordering may be at
fault.
(erc-networks--copy-over-server-buffer-contents): Pass old and new
buffers to `erc-networks--insert-transplanted-content'.
* lisp/erc/erc-stamp.el
(erc-stamp--defer-date-insertion-on-post-modify): Set `fn' slot of
`erc-stamp--date' instance to `ignore' when running the actual
callback in order to conserve a little space.
(erc-stamp--date-mode): Add and remove hook members for
`erc-networks--copy-server-buffer-functions' and
`erc-networks--transplant-target-buffer-function'.
(erc-insert-timestamp-left-and-right): Always clear
`erc-timestamp-last-inserted-right' to ensure a right stamp
accompanies every date stamp.
(erc-stamp--dedupe-date-stamps)
(erc-stamp--dedupe-date-stamps-from-buffer)
(erc-stamp--dedupe-date-stamps-from-target-buffer): New functions.
Date stamp behavior was revamped as part of bug#60936.
* lisp/erc/erc.el (erc-informational): New face.
(erc--insert-admin-message): New function to hide some "msg prop"
complexity from "upstream" libraries, like `erc-networks', and thus
avoid more forward-declarations. A less smelly approach would be to
devise a general interface owned by such libraries, or erc-common,
that `erc-mode' could then hook into on init.
(erc-display-message-highlight): Make face matching more limber to
accommodate the convention of face names lacking a "-face" suffix.
(erc-message-english-graft): New variable.
(erc-kill-channel): Inhibit execution of hook when
`erc-networks--target-transplant-in-progress-p' is non-nil.
* test/lisp/erc/erc-networks-tests.el
(erc-networks--rename-server-buffer--no-existing--orphan)
(erc-networks--rename-server-buffer--existing--reuse)
(erc-networks--rename-server-buffer--local-match)
(erc-networks--rename-server-buffer--local-nomatch): Use helper to
initialize markers.
* test/lisp/erc/erc-stamp-tests.el (erc-stamp--dedupe-date-stamps):
New test. (Bug#70928)
* etc/ERC-NEWS: Mention new flag `erc-killing-buffer-on-part-p' and
the renaming of `erc-kill-channel'.
* lisp/erc/erc-backend.el (erc-server-PART): Only kill a buffer on
behalf of `erc-kill-buffer-on-part' when the buffer hasn't already
been killed, and bind `erc-killing-buffer-on-part-p' to t when doing
so.
* lisp/erc/erc-log.el (erc-conditional-save-buffer): Don't save logs
when the buffer parameter is nil because that causes the server buffer
to be saved out. It's possible that user code relying on this
longstanding bug will be affected, however, by default, the server
buffer will also be saved out independently at designated junctures.
* lisp/erc/erc.el (erc-part-hook): Redo doc string.
(erc-killing-buffer-on-part-p): New variable, a flag to prevent
redundant execution of `erc-kill-channel-hook' members concerned with
parted channels.
(erc-kill-buffer-on-part): Tweak doc string.
(erc-kill-channel-hook): Use new name for `erc-kill-channel',
`erc-part-channel-on-kill'.
(erc-kill-channel, erc-part-channel-on-kill): Rename former to latter,
and inhibit execution when `erc-killing-buffer-on-part-p' is non-nil.
* test/lisp/erc/erc-scenarios-base-kill-on-part.el: New file.
(Bug#70840)
* lisp/progmodes/python.el (python-font-lock-keywords-maximum-decoration):
Fontify type hints of assignment statement. (Bug#69357)
* test/lisp/progmodes/python-tests.el
(python-font-lock-assignment-statement-11)
(python-font-lock-assignment-statement-12)
(python-font-lock-assignment-statement-13)
(python-font-lock-assignment-statement-18): Add fontification of type
hints.
(python-font-lock-assignment-statement-19): New test.
* etc/schema/dotnet-appconfig.rnc:
* etc/schema/dotnet-packages-config.rnc:
* etc/schema/dotnet-packages-props.rnc:
* etc/schema/dotnet-resx.rnc:
* etc/schema/msbuild.rnc:
* etc/schema/nuget.rnc:
* etc/schema/nuspec.rnc: New files.
* etc/schema/README: Document copyright status of above new files.
* etc/schema/schemas.xml: Use above new files to support Mono/.NET
development related XML files.
This change was discussed in:
https://lists.gnu.org/r/emacs-devel/2024-02/msg00638.html
* src/sfnt.c: Include stdbit.h.
(sfnt_count_leading_zero_bits) [!INT64_MAX]: Remove this function,
which was confusingly named as it actually returned 31 minus the
number of leading zero bits.
(sfnt_multiply_divide_2) [!INT64_MAX]: Use stdc_leading_zeros instead.
C23's <stdbit.h> in the long run should be better supported than
Gnulib's count-one-bits.h and similar headers, so switch to the
C23 primitives, with a Gnulib fallback for platforms lacking C23.
* admin/merge-gnulib (GNULIB_MODULES): Remove count-leading-zeros,
count-one-bits, count-trailing-zeros. Add stdc_bit_width,
stdc_count_ones, stdc_trailing_zeros.
* lib/count-leading-zeros.c, lib/count-leading-zeros.h:
* lib/count-one-bits.c, lib/count-one-bits.h:
* lib/count-trailing-zeros.c, lib/count-trailing-zeros.h: Remove.
* lib/stdbit.c, lib/stdbit.in.h, lib/stdc_bit_width.c:
* lib/stdc_count_ones.c, lib/stdc_leading_zeros.c:
* lib/stdc_trailing_zeros.c, m4/stdbit_h.m4:
New files, copied from Gnulib.
* lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate.
* src/data.c: Do not include count-one-bits.h, count-trailing-zeros.h.
Instead, rely on lisp.h including stdbit.h.
(Flogcount, Fbool_vector_count_population)
(Fbool_vector_count_consecutive): Use stdbit.h macros instead of
count-one-bits.h and count-trailing-zeros.h macros.
(shift_right_ull, count_one_bits_word, pre_value)
(count_trailing_zero_bits): Remove; no longer needed.
* src/lisp.h: Include stdbit.h instead of count-leading-zeros.h.
(elogb): Use stdbit.h macro instead of count-leading-zeros.h macro.
* lisp/minibuffer.el (minibuffer-completion-help): Fix earlier
mistake. Instead of altering a variable whose value is
immutable (and already captured in a saved list), move the
reference to said list to a lexical binding and alter that
list's second element instead.
https://lists.gnu.org/archive/html/emacs-devel/2024-05/msg00875.html
* lisp/use-package/use-package-core.el (use-package-split-when):
New utility function to split a list whenever a specified
predicate returns t.
(use-package-vc-valid-keywords): A new defconst to gather all
allowed keywords.
(use-package-normalize--vc-arg): Properly normalize the
':ignored-files' keyword, in that the following are all valid
ways of entering files:
:ignored-files "a"
:ignored-files ("a")
:ignored-files "a" "b" "c"
:ignored-files ("a" "b" "c")
(use-package-normalize/:vc): Adjust normalization, now that we
do not necessarily receive a valid plist as an input. (Bug#66567)
* test/lisp/use-package/use-package-tests.el
(use-package-test-normalize/:vc): Add tests for ':ignored-files'
keyword.
This works well with `window-tool-bar-mode', to be added in upcoming
commit. Then the default tool bar is displayed frame-wide and
mode-specific tool bars are displayed in the window that mode is
active in.
* lisp/tool-bar.el (tool-bar-always-show-default): New user option.
(tool-bar--cache-key, tool-bar-make-keymap-1): Return default tool bar
when option is set.
* doc/lispref/display.texi (Replacing Specs, Face Attributes):
Mention special considerations when a display string has a
':box' face attribute identical to the surrounding buffer text.
