Eliminate 'vtable--limit-string' in favor of the more efficient
'truncate-string-pixelwise'. Remove extraneous pre-measurement
calls to 'string-pixel-width' and ellipsis concatenation as
'truncate-string-pixelwise' does both.
The 'make-vtable' 'ellipsis' keyword can be a string to override
the default returned by 'truncate-string-ellipsis'.
* lisp/emacs-lisp/vtable.el (vtable--ellipsis): New defun.
(vtable-insert-object, vtable--insert): Use 'vtable--ellipsis'.
(vtable--insert-line, vtable--insert-header-line): Call
'truncate-string-pixelwise' instead of 'vtable--limit-string'.
(vtable--limit-string): Remove function.
* test/lisp/emacs-lisp/vtable-tests.el
(test-vtable--limit-string-with-face-remapped-buffer): Remove
test, obsoleted by misc-test-truncate-string-pixelwise.
* doc/misc/vtable.texi: Document that :ellipsis can be a string.
* doc/lispref/windows.texi (Window Sizes):
* src/window.c (Fwindow_body_height, Fwindow_total_height)
(Fwindow_total_width, Fwindow_body_width): Clarify that window
dimensions are returned in canonical columns and lines.
(Bug#80620)
This minor mode configures hs-minor-mode to use
indentation-based folding.
* lisp/progmodes/hideshow.el (hs-hideable-block-p): New
function.
(hs-indentation-respect-end-block): New option.
(hs-indentation--store-vars): New variable.
(hs-cycle-filter, hs-get-first-block-on-line, hs-get-near-block)
(hs-find-block-beg-fn--default): Adapt code to use
'hs-hideable-block-p'.
(hs-block-positions): Update.
(hs-indentation-mode): New minor mode.
* doc/emacs/programs.texi (Hideshow): Update documentation.
* etc/NEWS: Announce changes

(hideshow-check-indentation-folding): New test.
* doc/lispref/lists.texi:
* lisp/emacs-lisp/let-alist.el (let-alist): Improve docs.
Namely, clarify that 'let-alist' does not "see" symbols
introduced by macro-expansion in its body, and that the
generated code looks up symbols in the alist whether or not
they are actually used in runtime.
See also bug#79706 for some relevant discussion.
* doc/lispref/lists.texi (Building Lists): Document it.
* etc/NEWS: Mention it.
* lisp/emacs-lisp/shortdoc.el (list): Demonstrate it.
* lisp/subr.el (ensure-proper-list): Add it.
* doc/emacs/custom.texi (Newcomers Theme): Move to the beginning
of the node, so as to be visible even when the Emacs frame is
too small and wrap it in a conditional to not print the message
in non-Info outputs.
* doc/misc/use-package.texi (Install package): Add an example
block that doesn't use :rev, and instead shows that you can just
pass a URL as a string to :vc.
* doc/emacs/maintaining.texi (Looking Up Identifiers): Document
it.
* etc/NEWS (bindings): Mention it.
* etc/themes/newcomers-presets-theme.el (newcomers-presets): Add
it.

(global-xref-mouse-mode): Implement it.
Remove `error-data` from the new error API: it is not really
compatible with a more abstract view of error descriptors, and
in practice it seems to be used only in two ways (both of them rare):
- To add some contextual info to an error. We should maybe add
a dedicated support for that, but it's not clear what shape it
should take, ideally (there was a discussion about with Alan
and myself in emacs-devel a few years ago).
- To do some other massaging whose correctness is dubious anyway.
* doc/lispref/control.texi (Handling Errors): Remove `error-data`.
* lisp/epa-file.el (epa-file--find-file-not-found-function): Don't use
`error-data`.
(epa-file--error-add-context): New function, extracted from
`epa-file-insert-file-contents`.
(epa-file-insert-file-contents): Use it instead of `error-data`.
* lisp/subr.el (error-data): Delete function.
Define new functions to manipulate error descriptors and
add support for `signal` to *re*signal a previous error.
* src/eval.c (Fsignal): Make the second arg optional and document
the possibility of passing a whole error descriptor to re-signal it.
(signal_or_quit): Fix a few corner case issues when
DATA is `nil` and ERROR_SYMBOL is an error descriptor.
* lisp/subr.el (error-type-p, error--p, error-type, error-data)
(error-has-type-p, error-slot-value): New function.
* doc/lispref/control.texi (Handling Errors): Prefer "error descriptor"
to "error description". Use the new single-arg call to `signal` to
re-throw an error.
Document `error-type`, `error-data` and `error-slot-value`.
(Error Symbols): Document the new functions `error-type-p` and
`error-has-type-p`.
* lisp/vc/vc-dispatcher.el (vc-display-failed-async-commands):
New user option.
(vc-do-async-command): Use it.
* doc/emacs/vc1-xtra.texi (General VC Options):
* etc/NEWS: Document it.
* lisp/vc/vc-dispatcher.el (vc-do-command): Adjust message to
begin "Failed" not "Done" when command exits non-zero.
* lisp/vc/vc.el (vc-checkin): Adjust message to end in
"...failed" not "...done" when async command exits non-zero.
* doc/misc/viper.texi: Fix weird use of indexing, whereby many
index entries were placed _after_ the table which described the
functions or variables or keys, or even in the end of a @node
describing some subject. The index entries were moved to _before_
the text to which they pertain. Also, fix some incorrect
cross-references.
Walking the window tree is more reliable than using the selected
window. Implement 'get-mru-frame' on top of 'get-mru-frames'
using 'frame-use-time'.
* lisp/frame.el (frame-use-time): Change to walk the window tree
for the specified frame.
(get-mru-frames): New defun.
(get-mru-frame): Change to call 'get-mru-frames'.
* doc/lispref/frames.texi: Update documentation.

* etc/NEWS: Document the change.
Not a bug report, but this is from the emacs-devel thread
"Tree-sitter: Transcendental things".
Improve tree-sitter thing navigation functions to handle the
case where there are multiple nested parsers in the
buffer. Previously these functions just grab the node at point
and are limited to the parser of that node. Now these functions
will thoUrouly search through all parsers that covers point
before giving up.
* doc/lispref/parsing.texi: Mention the change.
* lisp/treesit.el (treesit--some): New macro.
(treesit--thing-sibling): Use the new macro, add a new PARSER
parameter.
(treesit-thing-prev):
(treesit-thing-next): Add PARSER parameter.
(treesit-thing-at):
(treesit-navigate-thing): Use the new macro, add a new PARSER
parameter. Also pass the PARSER arg to recursive calls and
calls to treesit-thing-prev, etc.
Also, document stuffing better.
* src/keyboard.c (stuff_buffered_input):
Give up on stuffing if it fails.
* src/sysdep.c (stuff_char): Return failure indication.
* lisp/emacs-lisp/package.el (package-upgrade-keep-previous):
Rename user option to 'package-retention-policy'.
(package--policy-type): New constant for policy types.
(package-retention-policy): New option.
(package-review-policy): Use new type constant.
(package--review-p): Rename and generalise to
'package-matches-selector-p'.
(package-matches-selector-p): New function.
(package-upgrade, package-menu--mark-upgrades-1): Respect
'package-retention-policy'.
* doc/emacs/package.texi (Package Installation): Document new option.
* etc/NEWS: Update NEWS entry. (Bug#79957)
* doc/lispintro/emacs-lisp-intro.texi (print-postscript-figures):
Set it only if we're outputting TeX.
(Lists diagrammed, Lists diagrammed, Lists diagrammed)
(Lists diagrammed, Lists diagrammed, Symbols as Chest)
(kill-ring-yank-pointer, lambda): Presume that
`print-postscript-figures` is set only for TeX output and remove
the `@tex...@end tex` around `@image` which do not seem relevant any more.
