(gnus-topic-insert-topic-line): Make the vars used in
`gnus-topic-line-format-spec` dynamically scoped since it seems
that they're sometimes accessed from functions called by
`gnus-topic-line-format-spec` :-(
* lisp/gnus/gnus-util.el (gnus--\,@): Move macro to here...
* lisp/gnus/gnus-art.el (gnus--\,@): .. from here.
* lisp/gnus/gnus.el (gnus-method-to-server): Apply DeMorgan.
* src/xdisp.c (try_window): Don't try checking the margins if the
window is vscrolled, as that could cause unnecessary recentering
when tall images are displayed. (Bug#46320)
* lisp/textmodes/enriched.el (enriched-mode-map): Don't rebind
beginning-or-line, because it makes `C-S-a' not mark the region,
and it doesn't allow actually moving to the beginning of the line
if the line starts with characters in `adaptive-fill-regexp'
(bug#22554).
* lisp/gnus/gnus-search.el (gnus-search-indexed-extract): This method
is documented to leave point at the end of the extracted search
result. The namazu implementation wasn't doing that.
These changes improve setting the language-environment and font
selection when MS-Windows returns useless "ZZZ" as the "language
name", which then disrupts all the setup of the locale-dependent
stuff, and in particular font selection.
* lisp/w32-fns.el (w32-charset-info-alist): Add an element for
"iso8859-5", in case LANG is set to something unusable, like
"ZZZ". This allows fonts capable of displaying Cyrillic
characters to be used even when language preferences are screwed.
* src/w32.c (init_environment): If GetLocaleInfo returns "ZZZ" as
the "language name" for LOCALE_USER_DEFAULT, try again with locale
ID based on what GetUserDefaultUILanguage returns. (Bug#39286)
To scroll up/down the current displayed occurrence/error
without abandon the Occur/Grep buffer.
Add also a command 'recenter-other-window' to recenter
the other window from any kind of buffer.
* lisp/window.el (recenter-other-window): New command.
Bind recenter-other-window to S-M-C-l (Bug#46119).
* lisp/simple.el (recenter-current-error): New command.
* lisp/progmodes/grep.el (grep-mode-map):
Delete bidings for n and p.
* lisp/progmodes/compile.el (compilation-minor-mode-map):
Move here the n and p bindings.
Bind `recenter-current-error' to l.
* lisp/replace.el (occur-mode-map):
Same.
* doc/emacs/windows.texi (Other Window):
* doc/emacs/display.texi (Recentering):
Document recenter-other-window.
* etc/NEWS (Changes in Specialized Modes and Packages in Emacs 28.1):
Announce the changes.
* doc/lispref/positions.texi (Text Lines): Revert previous change.
* lisp/simple.el (line-number-at-pos): Remove definition.
* lisp/simple.el (count-lines): Revert back to using
`forward-line', because there seems to be a disagreement on how
lines should be counted in a region...
* src/fns.c (Fline_number_at_pos): Rename from
Fline_number_at_position and adjust parameter list.
* doc/lispref/positions.texi (Text Lines): Document it.
* lisp/simple.el (count-lines): Use it.
(line-number-at-pos): Ditto.
* src/fns.c (Fline_number_at_position): New function (bug#22763).
This reverts commit 9e68413c7f.
This patch led to bug#46327:
x = [2 2]'
disp(x)
Which meant that the transpose operator was interpreted
as the start of a string.
* lisp/cus-edit.el (customize-changed): Rename from
customize-changed-options (bug#23085), since the old name doesn't
reflect what it does: It's not just about user options, but also
faces and the like.
(customize-changed-options): Make into an obsolete alias.
* doc/lispref/hash.texi (Creating Hash): Note that the printed
representation doesn't necessarily create a new table (bug#23417).
* doc/lispref/lists.texi (Rearrangement): Link to Self-Evaluating
Forms to further expand upon immutability.
* lisp/bindings.el: Define ctl-x-g-map and bind 'revert-buffer' to
'C-x x g' globally.
* doc/emacs/files.texi: Replace 'C-x g' with 'C-x x g'.
* etc/NEWS: Document the change (bug#46300).
* lisp/emacs-lisp/byte-opt.el (byte-optimize--lexvars)
(byte-optimize--vars-outside-condition)
(byte-optimize-form-code-walker, byte-optimize-let-form):
Clarify various aspects in the variable constant-propagation code,
as kindly pointed out by Stefan Monnier.
These are both conditions having the form (and A B) where A is
side-effect-free and B may be known to be nil at compile time.
The compiler will then warn about A being useless and thrown away.
The fix is to test B first.
* lisp/gnus/gnus.el (gnus-method-to-server):
Test `(not no-enter-cache)` first.
(gnus-server-get-method): Test `group` first.
Lexical variables bound to a constant value (symbol, number or string)
are substituted at their point of use and the variable then eliminated
if possible. Example:
(let ((x (+ 2 3))) (f x)) => (f 5)
This reduces code size, eliminates stack operations, and enables
further optimisations. The implementation is conservative, and is
strongly curtailed by the presence of variable mutation, conditions
and loops.
* lisp/emacs-lisp/byte-opt.el
(byte-optimize-enable-variable-constprop)
(byte-optimize-warn-eliminated-variable): New constants.
(byte-optimize--lexvars, byte-optimize--vars-outside-condition)
(byte-optimize--vars-outside-loop, byte-optimize--dynamic-vars):
New dynamic variables.
(byte-optimize--substitutable-p, byte-optimize-let-form):
New functions.
(byte-optimize-form-code-walker): Adapt clauses for variable
constprop, and add clauses for 'setq' and 'defvar'.
* test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp-test-var)
(bytecomp-test-get-var, bytecomp-test-identity)
(byte-opt-testsuite-arith-data): Add test cases.
* doc/lispref/frames.texi (Layout Parameters): Update entry on
'child-frame-border-width' parameter.
* src/frame.c (make_frame): Init child_frame_border_width to -1.
(Fframe_child_frame_border_width): Return internal border width if
child frame border width parameter is nil.
(gui_report_frame_params): Report nil as child frame border
width parameter if the frame value is negative.
* src/frame.h (FRAME_INTERNAL_BORDER_WIDTH): Return value of
child frame border width only if it is not negative.
* src/xfns.c (Fx_create_frame): Default child frame border to -1
when recording it in its frame slot via gui_default_parameter.
* src/nsfns.m (ns_set_child_frame_border_width): Handle nil ARG.
(Fx_create_frame): Default child frame border width parameter to
nil.
* src/w32fns.c (w32_set_child_frame_border_width): Handle nil ARG.
(Fx_create_frame): Default child frame border width parameter to
nil.
* src/xfns.c (x_set_child_frame_border_width): Handle nil ARG.
(Fx_create_frame): Default child frame border width parameter to
nil.
