* lisp/erc/erc-status-sidebar.el (erc-status-sidebar-singular,
erc-status-sidebar--singular-p): Replace option new in ERC 5.6 with
the latter, an internal flag.
(erc-status-sidebar-get-window): Use new name for option turned
ordinary variable `erc-status-sidebar--singular-p'.
(erc-status-sidebar-close): Add comment.
(erc-status-sidebar--open): New function containing the old body of
`erc-status-sidebar-open'.
(erc-bufbar-mode, erc-bufbar-enable, erc-bufbar-disable): Update
variable names. Close sidebar window on all frames when disabling,
and don't set mode variable to nil when enabling. These may have made
some practical sense but were illogical. For example, it's confusing
to leave `erc-status-sidebar--open' in `erc--setup-buffer-hook' while
reporting the mode as being disabled.
(erc-status-sidebar-open): Move to slightly later in same file, after
defining `erc-bufbar-mode'. When `erc-bufbar-mode' is active, always
create a sidebar if needed, even when another frame is already
displaying one.
(erc-status-toggle-sidebar): When `erc-bufbar-mode' is disabled,
revert to pre-5.6 behavior. When the module is enabled, adopt new
behavior of ensuring the current frame shows a sidebar, even if
another frame already has one.
(erc-status-sidebar-refresh): Save and restore `window-start' in all
windows showing a sidebar buffer after refreshing. Update option and
variable names.
(erc-status-sidebar-refresh-triggers): Add doc string, noting that the
variable is set locally when the option
`erc-status-sidebar-highlight-active-buffer' is non-nil.
(erc-status-sidebar--highlight-refresh-triggers): New variable
containing additional triggers enabled when the option
`erc-status-highlight-active-buffer' is non-nil.
(erc-status-sidebar--refresh-unless-input): New function to run
`erc-status-sidebar-refresh' unless input is pending or the selected
window's buffer is a minibuffer.
(erc-status-sidebar--post-refresh): Call `erc-status-sidebar-refresh'
wrapper `erc-status-sidebar--refresh-unless-input' instead.
(erc-status-sidebar-set-window-preserve-size): Update var name to
`erc-status-sidebar--singular-p'.
(erc-status-sidebar-mode): Run `erc-status-sidebar--post-refresh' on
`window-selection-change-functions' globally when highlighting active
buffers. (bug#63595)
* lisp/erc/erc-fill.el (erc-fill--wrap-continued-message-p): Return
nil when current message is a CTCP ACTION. This fixes a regression
introduced by 63d8b2a59a "Make erc-fill-wrap work with left-sided
stamps".
* test/lisp/erc/erc-fill-tests.el: (erc-fill-wrap--merge-action):
New test.
* test/lisp/erc/resources/fill/snapshots/merge-wrap-01.eld: New
test data file. (Bug#60936)
* lisp/doc-view.el (doc-view-ghostscript-program)
(doc-view--revert-buffer, doc-view--pdf-outline): Compare
'shell-command' / 'call-process' return values with 'eql' instead of
'=' to cater for the situation where the process received a signal.
* lisp/userlock.el (userlock--check-content-unchanged): Don't
assume 'file-truename' of FILENAME is always non-nil. It could be
nil if we are called from a temporary buffer where some Lisp
program has forcibly set 'buffer-file-name'. (Bug#64821)
* test/src/filelock-tests.el (filelock-tests--fixture): Set
'buffer-file-name' to the true name of the temporary file.
Patch by Mattias Engdegård <mattias.engdegard@gmail.com>.
(filelock-tests-detect-external-change): Quote the file names
passed to shell commands.
* lisp/help-fns.el (help-fns--analyze-function):
For aliases, use the base function name if at the end of the chain.
This fixes a regression introduced in d30fde6b0c.
Reported by Michael Heerdegen.
Implement char-before, backward-char and backward-word as compiler
macros instead of byte-compile handlers so that the source-level
optimiser gets to simplify the result. In particular, this removes
some branches.
* lisp/emacs-lisp/bytecomp.el (byte-compile-char-before)
(byte-compile-backward-char, byte-compile-backward-word): Remove.
(bytecomp--char-before, bytecomp--backward-char)
(bytecomp--backward-word): New.
* doc/lispref/os.texi (Desktop Notifications): Extend meaning of
:app-icon.
* etc/NEWS: Allow to use Icon Naming Specification for app-icon in
notifications-notify.
* lisp/notifications.el (notifications-notify): Allow to use Icon
Naming Specification for app-icon.
* lisp/image/image-dired.el (image-dired-thumb-naming): New user
option to control thumbnail name.
* lisp/image/image-dired-util.el (image-dired-thumb-name): Update
to use new user option and compute contents SHA-1 if needed.
(image-dired-contents-sha1): New function to compute the SHA-1 of the
first 4KiB of a file.
* lisp/tar-mode.el (pax-extended-attribute-record-regexp)
(tar-attr-vector): New variables.
(pax-gid-index, pax-gname-index, pax-linkpath-index)
(pax-mtime-index, pax-path-index, pax-size-index, pax-uid-index)
(pax-uname-index): New constants.
(pax-header-gid, pax-header-gname, pax-header-linkpath)
(pax-header-mtime, pax-header-path, pax-header-size)
(pax-header-uid, pax-header-uname): New accessors to pax header.
(pax-decode-string, tar-parse-pax-extended-header): New functions.
(tar-header-block-tokenize): Recognize and handle Posix-standard
pax extended header, and use its attributes instead of those in
the standard tar header. (Bug#64686)
* lisp/emacs-lisp/byte-opt.el (byte-opt--nary-comparison):
Fix a typo causing miscompilation of code such as (OP X),
where OP is <, >, <=, >= or =.
* test/lisp/emacs-lisp/bytecomp-tests.el
(bytecomp-tests--test-cases): Add test case.
Reported by Richard Copley.
By transforming the buffer's directory name, we can add
additional information to use during uniquifying. A basic
one: uniquifying buffer names based on the project name.
* lisp/progmodes/project.el (project-uniquify-dirname-transform): Add.
* lisp/uniquify.el (uniquify-dirname-transform-default)
(uniquify-dirname-transform): Add. (Bug#62621)
(uniquify-rationalize-file-buffer-names, uniquify-buffer-file-name):
Use 'uniquify-dirname-transform'.
* test/lisp/uniquify-tests.el (uniquify-home)
(uniquify-project-transform): Add tests.
* lisp/man.el (Man-completion-table): Quote special characters
before passing them to the shell.
(Man-name-regexp): Allow '@' and '[' in man-page names. (Bug#64795)
* lisp/emacs-lisp/lisp-mode.el (lisp-imenu-generic-expression):
Add defvar-keymap. We do not ignore (defvar-keymap FOO)
constructs in imenu as we do with (defvar FOO) since the former
constructs are generally not vacuous whereas the latter ones
often are. (Bug#64831)
* lisp/progmodes/cperl-mode.el (imenu-max-items): declare the
variable to silence an elint warning.
(cperl-short-docs): Reorder function description to match Perl's
perlfunc documentation. Add missing shortdocs from perlfunc.
Delete entries for operators which don't exist any more (EQ, NE
and friends). Shorten docstring lines to 80 chars or less.
* lisp/files-x.el (modify-file-local-variable-message): Suggest to
revert from the buffer's file only if that file exists; otherwise
suggest 'normal-mode'. (Bug#64844)
* lisp/userlock.el (userlock--check-content-unchanged): Support
the case where a file is locked before being written to from a
non file-visiting buffer. (Bug#64821)
* lisp/proced.el (proced-grammar-alist): Change the justify
value of the start attribute to 'left' instead of a fixed
value of 6. (Bug#64752)
(proced-format-start): Adjust the doc string.
* src/dispnew.c (mouse_prefer_closest_glyph): New global
variable.
(buffer_posn_from_coords):
* src/xdisp.c (remember_mouse_glyph): Respect
'mouse_prefer_closest_glyph'.
(mouse_fine_grained_tracking): Update documentation to
include 'mouse_prefer_closest_glyph' effects.
* doc/lispref/commands.texi (Accessing Mouse): Update
documentation to say what the new option does when enabled.
* lisp/cus-start.el (standard): New user option
'mouse-prefer-closest-glyph'.
* etc/ERC-NEWS: Mention that line endings have moved from the end to
the beginning of hidden messages.
* lisp/erc/erc-fill.el (erc-fill--wrap-ensure-dependencies): Warn when
users have `erc-legacy-invisible-bounds-p' enabled, and force it to
its default value of nil in the current buffer.
(erc-fill-wrap-mode, erc-fill-wrap-enable): Move business involving
compat variable for enabling legacy hidden-message behavior to helper.
* lisp/erc/erc-match.el (erc-match--hide-fools-offset-bounds): Move
internal variable from to main library file and rename to
`erc-legacy-invisible-bounds-p'. Also make obsolete and flip
semantics so a non-nil value enables the traditional behavior.
(erc-match--hide-message): Move to main library file and rename to
`erc--hide-message'. Add a property-value parameter instead of
hard-coding to `erc-match'. Also, condition behavior on renamed
compatibility flag `erc-legacy-invisible-bounds-p'.
(erc-hide-fools): Call `erc--hide-message' with own value for
`invisible' property specifically for fools. That is, use
`match-fools' rather than `erc-match' or `erc-match-fools' to save
room when visually inspecting. This retains the module name as a
prefix to hopefully minimize collisions with invisibility spec members
owned by non-ERC minor modes. The `timestamp' spec member owned by
erc-stamp likewise lacks a namespace prefix, but its feature/group
affiliation is self-evident.
(erc-match--modify-invisibility-spec): Use toggle command
non-interactively for adding and removing invisibility spec member.
(erc-match-toggle-hidden-fools): Add explicit override argument and
defer to general helper for actually modifying spec.
(erc-match--toggle-hidden): New helper for toggling invisibility
spec.
* lisp/erc/erc.el (erc--merge-prop): If new value is a list, prepend
onto existing. Add note about possible space optimization.
(erc-legacy-invisible-bounds-p): New obsolete compat variable to
enable traditional pre-5.6 invisibility interval on hidden messages.
Replaces `erc-match--hide-fools-offset-bounds-p' but has an inverted
meaning. The new default value of nil means invisibility covers a
shifted interval consisting of the message body plus the line ending
immediately preceding it.
(erc--hide-message): New function, formerly `erc-match--hide-message'
from erc-match.el introduced in ERC 5.6.
* test/lisp/erc/erc-scenarios-match.el:
(erc-scenarios-match--invisible-stamp): Fix comment and use API
function in interactive convenience setup.
(erc-scenarios-match--find-bol): New test helper.
(erc-scenarios-match--find-eol): Fix bug affecting interactive use.
(erc-scenarios-match--stamp-left-fools-invisible,
erc-scenarios-match--stamp-right-fools-invisible,
erc-scenarios-match--stamp-right-invisible-fill-wrap,
erc-scenarios-match--stamp-both-invisible-fill-static): Update
`invisible' property from `erc-match' to `match-fools'.
(erc-scenarios-match--stamp-right-fools-invisible,
erc-scenarios-match--stamp-both-invisible-fill-static): Move test
body to function of same name for use in multiple cases.
(erc-scenarios-match--stamp-right-fools-invisible--nooffset,
erc-scenarios-match--stamp-both-invisible-fill-static--nooffset): New
test variants asserting proper hiding with old pre-5.6 invisibility
interval.
* test/lisp/erc/erc-tests.el (erc-tests--equal-including-properties):
Relocate macro higher in same file.
(erc--merge-prop): New test. (Bug#64301)
* etc/ERC-NEWS: Remove all mention of option `erc-timestamp-align-to'
supporting a value of `margin', which has been abandoned. Do mention
leading white space before stamps now having stamp-related properties.
* lisp/erc/erc-backend.el (erc--reveal-prompt, erc--conceal-prompt):
New generic functions with default implementations factored out from
`erc--unhide-prompt' and `erc--hide-prompt'.
(erc--prompt-hidden-p): New internal predicate function.
(erc--unhide-prompt): Defer to `erc--reveal-prompt', and set
`erc-prompt' text property to t.
(erc--hide-prompt): Defer to `erc--conceal-prompt', and set
`erc-prompt' text property to `hidden'.
* lisp/erc/erc-compat.el (erc-compat--29-browse-url-irc): Don't
use `function-equal'.
* lisp/erc/erc-fill.el (erc-fill-wrap-margin-width,
erc-fill-wrap-margin-side): New options to control side and initial
width of `fill-wrap' margin.
(erc-fill--wrap-beginning-of-line): Fix bug involving non-string
valued `display' props.
(erc-fill-wrap-toggle-truncate-lines): New command to re-enable
`visual-line-mode' when toggling off `truncate-lines'.
(erc-fill-wrap-mode-map): Remap `toggle-truncate-lines' to
`erc-fill-wrap-toggle-truncate-lines'.
(erc-fill-wrap-mode, erc-fill-wrap-enable, erc-fill-wrap-disable):
Update doc string, persist a few local vars, and conditionally set
`erc-stamp--margin-left-p'. When deactivating, disable
`visual-line-mode' first.
(erc-fill--wrap-continued-message-p): Use `erc-speaker' instead of
heuristics when comparing nicks between consecutive messages.
(erc-fill-wrap-nudge): Update doc string and account for left-sided
stamps.
(erc-timestamp-offset): Add comment regarding conditional guard based
on function-valued option.
* lisp/erc/erc-stamp.el (erc-timestamp-use-align-to): Remove value
variant `margin', which was originally intended to be new in ERC 5.6.
This functionality was all but useless without the internal minor mode
`erc-stamp--display-margin-mode' active.
(erc-stamp-right-margin-width): Remove unused option new in 5.6.
(erc-stamp--display-margin-force): Remove unused function.
(erc-stamp--margin-width, erc-stamp--margin-left-p): New internal
variables.
(erc-stamp--init-margins-on-connect): New function for initializing
mode-managed margin after connecting.
(erc-stamp--adjust-right-margin, erc-stamp--adjust-margin): Rename
function to latter and accommodate left-hand stamps.
(erc-stamp--inherited-props): Move definition higher up in same file.
(erc-stamp--display-margin-mode): Update function name, and adjust
setup and teardown to accommodate left-handed stamps. Don't add
advice around `erc-insert-timestamp-function'.
(erc-stamp--last-prompt, erc-stamp--display-prompt-in-left-margin):
New function and helper var to convert a normal inserted prompt so
that it appears in the left margin.
(erc-stamp--refresh-left-margin-prompt): Helper for other modules to
quickly refresh prompt outside of insert hooks.
(erc--reveal-prompt, erc--conceal-prompt): New implementations for
when `erc-stamp--display-margin-mode' is active.
(erc-insert-timestamp-left): Convert to generic function and provide
implementation for `erc-stamp--display-margin-mode'.
(erc-stamp--omit-properties-on-folded-lines): New variable, an escape
hatch for propertizing white space before right-side stamps folded
over onto another line.
(erc-insert-timestamp-right): Don't expect `erc-timestamp-align-to' to
ever be the symbol `margin'. Move handling for that case to one
contingent on the internal minor mode `erc-stamp--display-margin-mode'
being active. Add text properties preceding stamps that occupy a line
by their lonesome. See related news entry for rationale. This is
arguably a breaking change.
* lisp/erc/erc.el (erc--refresh-prompt-hook): New hook variable for
modules to adjust prompt properties whenever it's refreshed.
(erc--refresh-prompt): Fix bug in which user-defined prompt functions
failed to hide when quitting in server buffers. Run new hook
`erc--refresh-prompt-hook'.
(erc-display-prompt): Add comment noting that the text property
`erc-prompt' now actually matters: it's t while a session is running
and `hidden' when disconnected.
* test/lisp/erc/erc-fill-tests.el (erc-fill--left-hand-stamps): New
test.
* test/lisp/erc/erc-stamp-tests.el
(erc-stamp-tests--use-align-to--nil,
erc-stamp-tests--use-align-to--t): New functions forged from old test
bodies to allow optionally asserting pre-5.6 behavior regarding
leading white space on right-hand stamps that exist on their own line.
(erc-timestamp-use-align-to--nil, erc-timestamp-use-align-to--t):
Parameterize with compatibility flag.
(erc-timestamp-use-align-to--margin,
erc-stamp--display-margin-mode--right): Rename test to latter.
* test/lisp/erc/erc-tests.el (erc-hide-prompt): Add some assertions
for new possible value of `erc-prompt' text property.
* test/lisp/erc/resources/fill/snapshots/stamps-left-01.eld: New test
data file. (Bug#60936)
* lisp/wid-edit.el (restricted-sexp): Turn value into a
string before reading.
(widget-field-value-create): Guard against value being nil,
so the field can be created even if the widget has a bad
default value. (Bug#59937)
When a macro expanded to a call to an obsolete macro, we failed
to emit a warning for that use of the obsolete macro.
* lisp/emacs-lisp/macroexp.el (macroexp-macroexpand):
Use `macroexpand-1` to check obsolecence of intermediate expansions.
* test/lisp/emacs-lisp/macroexp-tests.el
(macroexp--test-obsolete-macro): New test.
* lisp/proced.el (proced-mode): Force the header-line to scale
according to 'text-scale-adjust'.
(proced-header-line): Use width of the header-line's face's
characters as align-to units, not the width of the frame's
default face's font. (Bug#64752)
* src/xdisp.c (calc_pixel_width_or_height): Use font's
average_width or space_width, not max_width, as the correct
measure of the font's width. This is consistent with the rest of
the display engine.
* lisp/wid-edit.el (widget-choose): Test for stringp instead of
char-or-string-p, since substitute-command-keys should only apply
to choice values that are strings. (Bug#64046, Message #37)
In C, C++, Objective C, and Pike modes, regard \\ in a string
at EOL as a backslash followed by an escaped newline. In the
other languages, this remains regarded as an escaped backslash
followed by an invalid string terminator.
* lisp/progmodes/cc-defs.el (c-is-escaped, c-will-be-escaped):
Amend to observe the changed notion of escaped newlines.
* lisp/progmodes/cc-langs.el (c-string-escaped-newlines):
Unused, removed.
(c-escaped-newline-takes-precedence): New lang const and var.
(c-string-innards-re-alist): Amend, using the above new lang
var.
While 'mutool' supports many filetypes, 'mutool show' only
supports PDF files. This would lead to cryptic imenu errors
when opening other
file types (like EPUB) since we would parse the error output.
During my testing this caused 'imenu--index-alist' to have a
value of '(nil).
* lisp/doc-view.el (doc-view--pdf-outline): Error when 'mutool'
returns an error. Use 'call-process' to get the return value and
remove the call to 'shell-quote-argument' as 'call-process'
doesn't want any escapes.
(doc-view-mode): Handle possible error from 'doc-view-imenu-setup'.
(doc-view-imenu-enabled): Remove superfluous (and ... t).
(doc-view-imenu-setup): Remove check for mutool already ensured by
'doc-view-imenu-enabled' being non-nil.
(Bug#64516)
* lisp/progmodes/python.el (python-interpreter): Mention
new variable in documentation.
(python-interpreter-args): New custom variable.
(python-shell-interpreter, python-shell-interpreter-args)
(python-shell-interpreter-interactive-arg): Improve
documentation.
(python--list-imports, python--do-isort)
(python-fix-imports): Make process use customisable
arguments.
* lisp/cus-edit.el (custom-comment-preserve): New function.
(custom-redraw): Use it.
(custom-comment-create): Make sure :comment-shown is set to
t if the comment widget gets created.
(custom-face-value-create, custom-variable-value-create):
Recreate the custom-comment widget with the preserved value,
if any.
* lisp/cus-edit.el (custom-face-get-current-spec-unfiltered):
New function, extracted from custom-face-get-current-spec.
(custom-face-get-current-spec): Use it.
(custom-face-state-set): Take an optional argument, to decide
if we should check against a filtered or unfiltered spec.
(custom-face-value-create): Use the new optional argument.
