Also add a few missing docstrings.
* lisp/emacs-lisp/elisp-scope.el (elisp-scope-symbol-role-p)
(elisp-scope-read-symbol-role, elisp-scope-special-variables)
(elisp-scope-let, elisp-scope-let*): Add docstring.
(elisp-scope-counter, elisp-scope-callback)
(elisp-scope-current-let-alist-form, elisp-scope-local-new)
(elisp-scope-sym-pos, elisp-scope-sym-bare)
(elisp-scope-report, elisp-scope-special-variable-p)
(elisp-scope-let-1, elisp-scope-variable)
(elisp-scope-binding, elisp-scope-symbol): Rename, replace
'elisp-scope-' prefix with 'elisp-scope--' to indicate that
these are private. Update all references.
When a global minor mode is enabled by init-value rather than by
calling the major mode function, we failed to register it in
`global-minor-modes` (bug#79518).
* lisp/emacs-lisp/easy-mmode.el (define-minor-mode): Register
ourselves in `global-minor-modes` at top-level for global modes
with a non-nil init-value.
Also in the `modefun`, simply the code with `not` and `add-to-list`
and consolidate the local/global paths to update `*-minor-modes`.
* lisp/simple.el (global-minor-modes): Move to...
* lisp/subr.el (global-minor-modes): ...here so it's defined early enough
for `auto-compression-mode` to register itself.
Use argument specs to analyze complex widget types.
* lisp/emacs-lisp/elisp-scope.el (elisp-scope-widget-type)
(elisp-scope-widget-type-1)
(elisp-scope-widget-type-keyword-arguments)
(elisp-scope-widget-type-arguments)
(elisp-scope-widget-type-arguments-1): Delete, no longer used.
(custom-declare-variable, define-widget): Simplify analyzers.
(elisp-scope--match-spec-to-arg): Add new 'list', 'and', and
'plist-and-then' parametric specs, and add 'widget-type' as a
new recursive spec.
* test/lisp/progmodes/elisp-mode-resources/semantic-highlighting.el
Add test.
Rename a couple of faces to solidify the convention that the
face name 'elisp-foo' implies "references to foo", not "foo
definitions". For definitions we use 'elisp-deffoo' if foo is
only one word, or 'elisp-bar-baz-definition' otherwise.
* lisp/progmodes/elisp-mode.el (elisp-function-reference):
Rename to 'elisp-function'.
(elisp-macro-call): Rename to 'elisp-macro'.
(elisp-non-local-exit):
(elisp-unknown-call):
(elisp-special-form):
* lisp/emacs-lisp/elisp-scope.el:
* test/lisp/progmodes/elisp-mode-resources/semantic-highlighting.el:
Update references to renamed faces.
* lisp/progmodes/elisp-mode.el (elisp-fontify-semantically):
Fix typo in doc string.
(elisp--annotate-symbol-with-help-echo): Accept plain string
as value of ':help' symbol role property.
* lisp/emacs-lisp/elisp-scope.el: Remove unused symbol role
properties from all defined symbol roles. Use plain strings
for ':help' instead of wrapping them with 'cl-constantly'.
Cease 'require'ing 'cl-lib', no longer needed in runtime.
(elisp-scope-define-symbol-role): Update doc string.
* lisp/emacs-lisp/elisp-scope.el (elisp-scope-if-let): Fix
handling of a plain symbol as one the bindings in an
'if-let*' form, as in (if-let* (foo) 'bar).
* test/lisp/progmodes/elisp-mode-resources/semantic-highlighting.el:
Test it.
* lisp/emacs-lisp/elisp-scope.el
(elisp-scope--local-function-analyzer): New function.
(elisp-scope-flet, elisp-scope-labels)
(elisp-scope-named-let): Use it.
(elisp-scope-cl-macrolet): Check that argument is
'symbol-with-pos-p' before calling 'symbol-with-pos-pos'.
* lisp/emacs-lisp/elisp-scope.el (elisp-scope-1): All
special-forms should have an associated analyzer, so drop
fallback handling for unknown special-forms.
* lisp/emacs-lisp/elisp-scope.el
(elisp-scope-local-definitions): New variable. Replaces...
(elisp-scope-flet-alist, elisp-scope-macrolet-alist): these.
Removed, no longer used.
(elisp-scope-1, elisp-scope--handle-quoted): Update.
(elisp-scope-with-local-definition): New macro.
(elisp-scope-flet, elisp-scope-labels, elisp-scope-named-let)
(elisp-scope-cl-macrolet): Use it.
* lisp/emacs-lisp/elisp-scope.el (elisp-scope-flet)
(elisp-scope-labels, elisp-scope-cl-macrolet): Add argument
'outspec' and pass it down to 'elisp-scope-n'.
* lisp/emacs-lisp/elisp-scope.el
(special-variable-declaration): New symbol role.
(defvar): Update analyzer to distinguish between
declarations and definitions.
(defconst): Add a separate analyzer.
* lisp/progmodes/elisp-mode.el
(elisp-special-variable-declaration): New face.
* src/igc.c (Figc__describe_arena): New wrapper for ArenaDescribe.
(syms_of_igc): Register it.
* lisp/emacs-lisp/igc.el (igc-describe-arena): New command.
* lisp/emacs-lisp/igc.el (igc--number-format): New variable.
(igc--format-bytes-human-readable, igc--format-bytes,
igc--format-bytes-cell, igc--format-avg-cell):
(igc--insert-info): Use them
(igc-cycle-number-format): New command.
(igc-stats-mode): Bind it to n.
* lisp/emacs-lisp/elisp-scope.el
(elisp-scope-add-symbol-roles-to-describe-symbol): New
autoloaded function intended for user configs, hooks
`elisp-scope-describe-symbol-role' into `describe-symbol'.
Extend the "type" system (to be renamed to "spec" in
subsequent commit) of elisp-scope.el with a plist spec.
This allows us to define a spec for the 'slots' argument of
'eieio-defclass-internal'. Also add a 'cl-type' spec,
describing the type specifications used by 'cl-typep', and
replace the 'equal' spec with a more general 'member' spec,
like we have in 'cl-typep'.
