Re: [ELPA] New package: phps-mode

[Christian Johansson]

Ah I missed that, the original re2c regex is

[a-zA-Z_\x80-\xff][a-zA-Z0-9_\x80-\xff]*

(from https://github.com/php/php-src/blob/master/Zend/zend_language_scanner.l#L1252)

But I’m not sure about the equivalent in emacs-lisp but I know PHP does not fully support UTF-8 yet.

Is the equivalent

"[a-zA-Z_\u0080-\u00FF][a-zA-Z0-9_\u0080-\u00FF]*"

?

Thanks for your review, I should have fixed all those items now and pushed them to ELPA

(defvar phps-mode-lexer-LABEL

"[a-zA-Z_\u0080-\u00FF][a-zA-Z0-9_\x80-\xff]*"

Unfinished?

It looks like PHP accepts any Unicode character above and including U+0080 in labels implicitly, by including 80-ff at the byte level and the implicit fact that most PHP code is in UTF-8. So your regexp would probably be something like

"[A-Za-z_[:nonascii:]][0-9A-Za-z_[:nonascii:]]*"

You could always try and see if your code correctly treats $γνῶσις, say.
