Improve the accuracy of `xref-find-definitions` by inferring the
likely namespace of the sought identifier from its context.
This reduces the number of irrelevant search hits when it is clear
what kind of identifier is being looked for (such as showing a
variable when the user looks for a function).
Co-written with Dmitry Gutov.
* lisp/progmodes/elisp-mode.el (elisp--xref-list-index)
(elisp--xref-infer-namespace, xref-backend-identifier-at-point): New.
(xref-backend-definitions): Use the buffer position for inferring.
(elisp--xref-find-definitions): Use the inferred namespace.
(xref-backend-apropos): Adapt call.
* test/lisp/progmodes/elisp-mode-tests.el (elisp-mode-test--with-buffer)
(elisp-mode-with-buffer, elisp-mode-infer-namespace): New tests.
* lisp/window.el (pop-up-frame-alist, same-window-buffer-names)
(same-window-regexps, pop-up-frames, pop-up-windows): In
doc-strings say that these options are maintained for backward
compatibility only (Bug#50518).
* doc/emacs/frames.texi (Tab Bars): Improve wording, indexing, and
cross-references. Make sure each command is mentioned by its name
when it is called out by the key sequence. Index entries should
precede @item lines in a @table.
* lisp/erc/erc-track.el (erc-track-modified-channels): Fix what is a
probable bug when a new insert event happens for a buffer that was not
tracked or for which no mode line face was selected: in this case,
stop treating the latest buffer's face (first in list) as the previous
one, which could be overridden with an older one (in FACES' rest), as
if it had happened after.
* lisp/erc/erc-track.el (erc-track-find-face): Declare obsolete and
rewrite as 'erc-track-select-mode-line-face', changing the function
arguments, so that it is very clear what the current algorithm is.
No functional changes. Performance improvements. Clarify the
documentation and remove the part on some faces being lists, which
clearly does not apply.
(erc-track-modified-channels): Replace calls to 'erc-track-find-face'
with calls to 'erc-track-select-mode-line-face', preserving the
existing behavior.
(erc-modified-channels-alist): Change the reference to
'erc-track-select-mode-line-face' in the documentation following the
rename.
* etc/NEWS: Announce the change.
Co-authored-by: Amin Bandali <bandali@gnu.org>
* lisp/erc/erc-track.el (erc-modified-channels-alist): Clarify what
the list contains. Add references to variables and functions involved
in displaying tracked buffers from this list.
(erc-make-mode-line-buffer-name): Describe exactly the algorithm, and
reference custom variables that influence it.
* lisp/erc/erc-track.el (erc-modified-channels-alist): Fix the
docstring: each element is a dotted list where the last cdr is
sometimes a proper list, making the element only sometimes a proper
list.
* lisp/progmodes/bug-reference.el (bug-reference-gitea-instances)
(bug-reference-gitlab-instances,bug-reference-sourcehut-instances):
Delete defvars. Those are replaced with bug-reference-forge-alist.
(bug-reference-forge-alist): New variable.
(bug-reference--build-forge-setup-entry): New cl-defgeneric with
methods for github, gitlab, gitea, and sourcehut instances.
(bug-reference--setup-from-vc-alist): Use bug-reference-forge-alist
and bug-reference--build-forge-setup-entry.
* doc/emacs/maintaining.texi (Bug Reference): Mention that the first
group in bug-reference-bug-regexp defines the overlay bounds. Also
mention bug-reference-forge-alist in VCS setup section.
* lisp/calc/calc-graph.el (calc-gnuplot-check-for-errors):
* lisp/calendar/holidays.el (list-holidays):
Dodge 'save-excursion+set-buffer' warnings that appeared after
the progn flattening was introduced.
Replace uses of a variable aliasing another variable with that aliased
variable, to allow for variable removal when possible. This also
enables opportunities for other optimisations. Example:
(let ((y x)) (f y)) => (f x)
The optimisation is only performed if both aliased and aliasing
variables are lexically bound. Shadowing bindings are α-renamed when
necessary for correctness. Example:
(let* ((b a) (a EXPR)) (f a b))
=> (let* ((a{new} EXPR)) (f a{new} a))
* lisp/emacs-lisp/byte-opt.el (byte-optimize--aliased-vars): New.
(byte-optimize-form-code-walker): Cancel aliasing upon mutation.
(byte-optimize--rename-var-body, byte-optimize--rename-var): New.
(byte-optimize-let-form): Add the optimisation.
* test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp-tests--test-cases):
Add relevant test cases.
* lisp/net/tramp-gvfs.el (tramp-gvfs-handle-make-directory): Simplify.
* lisp/net/tramp-sh.el (tramp-methods) <telnet, nc>: Don't use
"%n" marker.
* test/lisp/net/tramp-tests.el (tramp-test13-make-directory): Merge with
`tramp-test-make-directory-helper' and
`tramp-test13-make-directory-with-file-modes'.
(tramp-test44-asynchronous-requests): Use always the same
operation in timer.
* progmodes/python.el (python-shell-eval-file-setup-code): Look for a
file coding cookie on the Python rather than on the Emacs side, to
avoid additional file transfers.
(python-shell--save-temp-file): Allow argument to be a buffer.
(python-shell-send-file): Address the case where the selected file and
the inferior process are on different machines (bug#50516).
* lisp/progmodes/python.el (python-shell-completion-at-point): cache
results, since computing them involves talking with the inferior
process and, potentially, network communications
(python-shell--capf-cache): new variable, for cache
(python-shell-completion-get-completions)
(python-shell-completion-native-get-completions): 'import' argument is
not needed anymore.
(python-shell-completion-native-setup)
(python-shell-completion-native-try): pass the setup code
synchronously, to avoid printing a message in the shell (bug#50459).
* src/xterm.c (x_draw_image_relief):
* src/w32term.c (w32_draw_image_relief): Fix the display of
tab-bar buttons when mouse pointer moves off the button.
(Bug#50424)
* src/keyboard.c (make_lispy_position): Call
'window_from_coordinates' with last 2 arguments non-zero, to have
it report on tool-bar and tab-bar positions. Tweak the return
value according to the expectations of 'make_lispy_event'.
(make_lispy_event): No more need to inject "tab-bar" into a click
event on the tab bar: it's already there.
Formerly, bug-reference-fontify placed the overlay on the complete
match of bug-reference-bug-regexp. That made it impossible to encode
constraints like "must not match at BOL" in the regexp without messing
up fontification. Therefore, now it establishes the contract that
subexpression 1 defines the overlay region. Subexpression 2 must
still match the part of the bug reference injected into
bug-reference-url-format if that's a string. If its a function, the
interpretation of subexpressions > 1 is up to the function.
For backwards compatibility, bug-reference-fontify checks if the
bounds of subexpression 2..10 are within the bounds of subexpession
1. If not, or subexpression 1 doesn't even exist/match, we fall back
to placing the overlay from (match-beginning 0) to (match-end 0) but
issue a warning.
* lisp/progmodes/bug-reference.el (bug-reference-bug-regexp): Document
contract that subexpression 1 defines the overlay region and adapt the
default value accordingly.
(bug-reference--nonconforming-regexps): New internal variable.
(bug-reference--overlay-bounds): New function.
(bug-reference-fontify): Place overlay on subexpression 1's bounds if
bug-reference-bug-regexp conforms to the documented contract.
(bug-reference--setup-from-vc-alist): Adapt regexps to new contract.
* doc/emacs/maintaining.texi (Bug Reference): Adapt regexp used in
example.
