* lisp/progmodes/ruby-ts-mode.el (ruby-ts--font-lock-settings):
Improve highlighting in patterns: highlight values not keys as
variable in the usual case; highlight keys when no value;
highlight the "as pattern" variable.
* lisp/font-lock.el (font-lock-regexp-face): New face.
* lisp/progmodes/typescript-ts-mode.el
(typescript-ts-mode--font-lock-settings):
* lisp/progmodes/ruby-ts-mode.el (ruby-ts--font-lock-settings):
* lisp/progmodes/js.el (js--treesit-font-lock-settings):
Use it for regexps.
* etc/NEWS: Mention the addition.
* lisp/progmodes/ruby-ts-mode.el
(ruby-ts--font-lock-settings): Highlight destructured parameters,
lambda parameters, identifiers in pattern matching clauses
(array/hash) and exception variables.
Move the 'symbol' matchers lower to make 'hash_key_symbol' lower
priority than hash keys in match patterns.
* lisp/progmodes/ruby-ts-mode.el (ruby-ts--font-lock-settings):
Bring back the 'assignment' feature.
(ruby-ts-mode): Replace the unused 'variable' with 'assignment'. Use
the level 3 for consistency with other ts modes.
Update the Commentary as well.
* lisp/progmodes/ruby-ts-mode.el (ruby-ts-mode):
Split the 'builtin' feature in two: 'builtin-constant' and
'builtin-variable'.
(ruby-ts-highlight-predefined-constants):
Drop the user option, the highlighting granularity can be chosen
using treesit-font-lock-recompute-features.
(ruby-ts--font-lock-settings): Update accordingly.
(ruby-ts--predefined-constants, ruby-ts--predefined-variables):
Fix docstrings.
* lisp/progmodes/ruby-ts-mode.el
(ruby-ts-add-log-current-function): Fix the case when point is
between two methods. 'treesit-node-at' returs the 'def' node of
the method after point in such case, so it behaved like point was
inside the method below.
* test/lisp/progmodes/ruby-ts-mode-tests.el
(ruby-ts-add-log-current-method-outside-of-method):
Update the test case.
* test/lisp/progmodes/ruby-mode-tests.el
(ruby-add-log-current-method-outside-of-method):
Mirror that change.
* lisp/progmodes/ruby-mode.el (ruby-base-mode):
New major base mode, to set up common vars and hooks.
(ruby-mode-variables): Delete. Move most code to ruby-base-mode.
And some -- to ruby-mode body.
(ruby-mode): Derive from ruby-base-mode. Also move some setup
to there.
* lisp/progmodes/ruby-ts-mode.el (ruby-ts-mode):
Derive from ruby-base-mode. Remove duplicating settings.
* lisp/progmodes/ruby-ts-mode.el (ruby-ts--align-keywords):
Fix for 'def' (which was misread as 'method' in the check).
(ruby-ts--indent-rules): Indent the curly block closer the same
way as the 'do ... end' closer.
* lisp/progmodes/ruby-ts-mode.el (ruby-ts--font-lock-settings):
Use more standard faces for regexp literals and string
interpolation delimiters (following js-ts-mode).
* lisp/progmodes/ruby-ts-mode.el (ruby-ts--font-lock-settings):
Use font-lock-string-face for %w() and `...`.
Use font-lock-constant-face (just like we do for symbol literals)
for symbol array literals, %i().
Combine the matchers for string content and heredocs.
* etc/NEWS: Mention the new mode.
* lisp/progmodes/ruby-ts-mode.el: New file.
* test/lisp/progmodes/ruby-ts-mode-tests.el: New file.
* lisp/progmodes/eglot.el (eglot-server-programs):
Add ruby-ts-mode to the Ruby entry.
