* doc/lispref/control.texi (Destructuring with pcase Patterns):
Clarify the kind of "unspecified" behavior that can occur when
the destructing pattern does not match the value.
"why does my set-fontset-font call not work for symbols" is a common
question, and it's because 'use-default-font-for-symbols' is not
discoverable enough.
* doc/emacs/mule.texi (Modifying Fontsets): Mention it here.
* doc/lispref/display.texi (Fontsets): And here.
* src/fontset.c (Fset_fontset_font): And most importantly here.
It's a common name for this function and symmetric with respect to
`take`. It's also a lot less awkward to type and say.
* lisp/subr.el (drop): New alias.
* doc/lispref/lists.texi (List Elements): Document. Mention the
equation tying `take` and `drop` together.
* etc/NEWS: Announce.
Change `function` so that when evaluating #'(lambda ...)
we return an object of type `interpreted-function` rather than
a list starting with one of `lambda` or `closure`.
The new type reuses the existing PVEC_CLOSURE (nee PVEC_COMPILED)
tag and tries to align the corresponding elements:
- the arglist, the docstring, and the interactive-form go in the
same slots as for byte-code functions.
- the body of the function goes in the slot used for the bytecode string.
- the lexical context goes in the slot used for the constants of
bytecoded functions.
The first point above means that `help-function-arglist`,
`documentation`, and `interactive-form`s don't need to
distinguish interpreted and bytecode functions any more.
Main benefits of the change:
- We can now reliably distinguish a list from a function value.
- `cl-defmethod` can dispatch on `interactive-function` and `closure`.
Dispatch on `function` also works now for interpreted functions but still
won't work for functions represented as lists or as symbols, of course.
- Function values are now self-evaluating. That was alrready the case
when byte-compiled, but not when interpreted since
(eval '(closure ...)) signals a void-function error.
That also avoids false-positive warnings about "don't quote your lambdas"
when doing things like `(mapcar ',func ...)`.

* src/lread.c (bytecode_from_rev_list):
* lisp/simple.el (function-documentation):
* lisp/help.el (help-function-arglist): Remove the old `closure` case
and adjust the byte-code case so it handles `interpreted-function`s.
* lisp/emacs-lisp/cl-preloaded.el (closure): New type.
(byte-code-function): Add it as a parent.
(interpreted-function): Adjust parent (the type itself was already
added earlier by accident).

new representation.
(byte-compile): Use `interpreted-function-p`.
* lisp/emacs-lisp/byte-opt.el (byte-compile-inline-expand): Adjust to

* src/dispextern.h (face, face_underline_type, syms_of_xfacse)
(internal-set-lisp-face-attribute)
(gui_supports_face_attributes_p): Add definitions for new
underline styles of Double-line, Dots and Dashes. Rename
FACE_UNDER_LINE and FACE_UNDER_WAVE to make definitions
consistent. Delete tty_underline_p from the face struct and use
just underline going forward. Add a flag to check whether styled
underlines are available.
* lisp/cus-face.el (custom-face-attributes): Add entries for
Double-line, Dots and Dashes so they can be set through
`customize'.
* src/termchar.c (tty_display_info): Add an entry for the escape
sequence to set the underline style and color on terminal frames.
* src/term.c (init_tty, tty_capable_p, turn_on_face): Read and
save the underline style escape sequence from the Smulx termcap
(alternatively if the Su flag is set use a default sequence).
Allow checking for support of styled underlines in the current
terminal frame. Output the necessary escape sequences to activate
a styled underline on turn_on_face; this is currently only used
for the new special underline styles, a default straight underline
will still use the "us" termcap. Output escape sequence to set
underline color when set in the face and supported by the tty.
Save a default value for this sequence on init_tty when styled
underlines are supported.
* src/xfaces.c (tty_supports_face_attributes_p, realize_tty_face)
(map_tty_color): Assert whether styled underlines are supported by
the current terminal on display-supports-face-attributes-p checks.
Populate the correct underline style and color in the face spec
when realizing a face. Allow map_tty_color to map underline
colors alongside foreground and background. The interface of
map_tty_color was amended to allow the caller to supply the
underline color instead of accessing it through the face
attributes. (bug#62994)
* src/xterm.c (x_draw_glyph_string): Updated to use renamed
FACE_UNDERLINE_SINGLE and FACE_UNDERLINE_WAVE face_underline_type
enumerations.
* doc/lispref/compile.texi (Eval During Compile):
`regexp-opt` makes for a poor example because as a pure function it
doesn't need `eval-when-compile` for constant inputs.
- Add a new field last_changed_ranges to tree-sitter parser object.
- Add a new function treesit-parser-changed-ranges
* doc/lispref/parsing.texi (Using Parser): Add the function in
tree-sitter manual.
* src/treesit.c (treesit_get_changed_ranges): New function, refactored
out of treesit_call_after_change_functions.
(treesit_call_after_change_functions): Pull out
treesit_get_changed_ranges.
(treesit_ensure_parsed): Save the changed ranges to the parser object.
(make_treesit_parser): Initialize the new parser field
last_changed_ranges.
(Ftreesit_parser_changed_ranges): New function.
(Qtreesit_unparsed_edits): New error.
* src/treesit.h (Lisp_TS_Parser): New field.
* doc/lispref/peg.texi (Parsing Expression Grammars): "lambda form"
isn't really a meaningful term. Prefer plain "function", though in this
case we've used "anonymous function" to avoid ambiguity.
* doc/lispref/peg.texi: Make more use of defmac/defmacro, and try to
clarify the relationships between the various macros and functions.
* lisp/progmodes/peg.el (peg-parse): Remove claim that PEXS can also be
a single list of rules.
* doc/lispref/peg.texi: Make more use of defmac/defmacro, and try to
clarify the relationships between the various macros and functions.
* lisp/progmodes/peg.el (peg-parse): Remove claim that PEXS can also be
a single list of rules.
* lisp/emacs-lisp/lisp.el (forward-sexp-default-function):
New function with body from 'forward-sexp' (bug#68993).
(forward-sexp-function): Change the default value from nil to
'forward-sexp-default-function'.
(forward-sexp): Use either 'forward-sexp-function' or
'forward-sexp-default-function'.
* lisp/treesit.el (treesit-forward-sexp): In nodes of type 'text'
fall back to 'forward-sexp-default-function'. Improve docstring.
* doc/lispref/positions.texi (List Motion): Fix pxref.
When `define-globalized-minor-mode` was introduced (Emacs-22),
`run-mode-hooks` was brand new, so we could not expect all major
modes to use it and we had to rely on brittle workarounds to try
and approximate `after-change-major-mode-hook`.
These workarounds have undesirable side effects, and (we hope)
they're not needed any more now that virtually all major modes
have been changed to use `run-mode-hooks` (or
`define-derived-mode`).
* lisp/emacs-lisp/easy-mmode.el (define-globalized-minor-mode):
Rely only on `after-change-major-mode-hook`, remove the "cmhh"
[typo for the intended "cmmh", BTW] workaround.
* doc/lispref/modes.texi (Mode Hooks): Clarify the importance of
`after-change-major-mode-hook` w.r.t `define-globalized-minor-mode`.
(Defining Minor Modes): Rewrite the explanation of which buffers
are affected, including adjusting it to the fact that
`fundamental-mode` has used run `run-mode-hooks` for last 10 years.
This new package provides an API that is easier to use right than
our `*-change-functions` hooks.
The patch includes changes to `diff-mode.el` and `eglot.el` to
make use of this new package.
* lisp/emacs-lisp/track-changes.el: New file.
* test/lisp/emacs-lisp/track-changes-tests.el: New file.
* doc/lispref/text.texi (Tracking changes): New subsection.
* lisp/progmodes/eglot.el: Require `track-changes`.
(eglot--virtual-pos-to-lsp-position): New function.
(eglot--track-changes): New var.
(eglot--managed-mode): Use `track-changes-register` i.s.o
`after/before-change-functions` when available.
(eglot--track-changes-signal): New function, partly extracted from
`eglot--after-change`.
(eglot--after-change): Use it.
(eglot--track-changes-fetch): New function.
(eglot--signal-textDocument/didChange): Use it.
* lisp/vc/diff-mode.el: Require `track-changes`.
Also require `easy-mmode` before the `eval-when-compile`s.
(diff-unhandled-changes): Delete variable.
(diff-after-change-function): Delete function.
(diff--track-changes-function): Rename from `diff-post-command-hook`
and adjust to new calling convention.
(diff--track-changes): New variable.
(diff--track-changes-signal): New function.
(diff-mode, diff-minor-mode): Use it with `track-changes-register`.
* src/xdisp.c (note_fringe_highlight): New function.
(note_mouse_highlight): Call it when the mouse is on the fringes.
* src/frame.c (syms_of_frame) <left-fringe-help>
<right-fringe-help>: DEFSYM them.
* etc/NEWS:
* doc/lispref/text.texi (Special Properties):
* doc/lispref/display.texi (Other Display Specs): Document the new
properties.
* etc/TODO: Remove the todo item about this.
* doc/lispref/parsing.texi (Retrieving Nodes): Mention new kinds of
predicate argument that the tree-traversing functions accept (which are
thing symbols and thing definitions).
(User-defined Things): New node dedicated to thing definition and
navigation functions.
* doc/lispref/commands.texi (Focus Events): Add
documentation for the structure of 'switch-window' events.
Make sure to be clear when referring to window system windows
vs Emacs windows.
* doc/lispref/windows.texi (Mouse Window Auto-selection):
Adding cross-reference to "Focus Events". (Bug#69915)
* src/json.c (Fjson_insert): Precise the behaviour when the current
buffer is multibyte and unibyte, respectively.
* doc/lispref/text.texi (Parsing JSON): Refer to the right function.
