Ciao,
this patch corrects the indentation of the control structure without closing
brackets (or without the end keyword... in the case of the alternative
syntax). It supports font locking of the “asymmetric property visibility ”
introduced with grammar v0.23.3 and so-called magic methods. And others small
fix. And others small bug I discovered while writing the tests..
Thank you.
Vincenzo

Subject: [PATCH] Fix php-ts-mode better indentation and font locking.
Incomplete compound_statement or colon_block (statement-group without a
closing brace or closing keyword) that are not inside a function or
method are not recognized as such by tree-sitter-php.
A new function 'php-ts-mode--open-statement-group-heuristic' handles
this case. Font locking of magic methods and better support for
alternative control structure syntax.
Support for latest grammar version.
* lisp/progmodes/php-ts-mode.el
(php-ts-mode--language-source-alist): Updated grammar version.
(php-ts-mode--possibly-braceless-keyword-re): Regular expression for
braceles keyword.
(php-ts-mode--open-statement-group-heuristic): New function.
(php-ts-mode--parent-html-bol): Use the new function and doc fix.
(php-ts-mode--parent-html-heuristic): Use the new function and doc fix.
(php-ts-mode--indent-styles): Use the new function and add 'colon_block'
support.
(php-ts-mode--class-magic-methods): New predefined magic methods list.
(php-ts-mode--test-namespace-name-as-prefix-p): Doc fix.
(php-ts-mode--test-namespace-aliasing-clause-p): Fix the test and doc.
(php-ts-mode--test-namespace-use-group-clause-p): Doc fix.
(php-ts-mode--test-visibility-modifier-operation-clause-p): New function
for the new asymmetric property visibility feature of PHP 8.4.
(php-ts-mode--font-lock-settings): Font lock for class magic methods and
alternative syntax. Better font lock for 'instanceof'. Use
'font-lock-function-call-face' for scoped and member call expression.

Thank you.
I have two questions about this:
. will the code which uses the "asymmetric property visibility" also
work without problems with versions of the grammar library before
0.23.3?
. do you consider the code changes to be tested well enough and thus
safe to be installed on the emacs-30 release branch?
I'd prefer to install on emacs-30, because this mode is new in Emacs
30, unless you are not sure the code is safe enough.

Yes, I tested it with older versions of the grammars.
'php-ts-mode--test-visibility-modifier-operation-clause-p' is used to check if
this new feature is defined or not, and behaves accordingly.

Yes, I've been using this patch at work for about a week and haven't had any
problems.

I was about to install this, but byte-compiling the modified file
yields the following warnings:
ELC progmodes/php-ts-mode.elc

Could you please fix these and resubmit the patch?

Date: Thu, 10 Oct 2024 16:06:37 +0200
Subject: [PATCH] Fix php-ts-mode better indentation and font locking.
Incomplete compound_statement or colon_block (statement-group without a
closing brace or closing keyword) that are not inside a function or
method are not recognized as such by tree-sitter-php.
A new function 'php-ts-mode--open-statement-group-heuristic' handles
this case. Font locking of magic methods and better support for
alternative control structure syntax.
Support for latest grammar version.
* lisp/progmodes/php-ts-mode.el
(php-ts-mode--language-source-alist): Updated grammar version.
(php-ts-mode--possibly-braceless-keyword-re): Regular expression for
braceles keyword.
(php-ts-mode--open-statement-group-heuristic): New function.
(php-ts-mode--parent-html-bol): Use the new function and doc fix.
(php-ts-mode--parent-html-heuristic): Use the new function and doc fix.
(php-ts-mode--indent-styles): Use the new function and add 'colon_block'
support.
(php-ts-mode--class-magic-methods): New predefined magic methods list.
(php-ts-mode--test-namespace-name-as-prefix-p): Doc fix.
(php-ts-mode--test-namespace-aliasing-clause-p): Fix the test and doc.
(php-ts-mode--test-namespace-use-group-clause-p): Doc fix.
(php-ts-mode--test-visibility-modifier-operation-clause-p): New function
for the new asymmetric property visibility feature of PHP 8.4.
(php-ts-mode--font-lock-settings): Font lock for class magic methods and
alternative syntax. Better font lock for 'instanceof'. Use
'font-lock-function-call-face' for scoped and member call expression.
