Summary: PHP mode "//" comment syntax highlighting is incorrect

Initial Comment:
PHP mode included in Jedit 4.2pre13 ignores the fact,
that the // comment is not always until the end of the
line - it comments out the text between '//' and end of
line OR '//' and end of a block:

// ok, all of this is a comment

//"<?= 'This is a coment but ';?>"; all after '?>' is
not a comment, but an html code

I hope I do not post this at a wrong place. 

Sincerely Yours Kuba

Oops, this is embarassing, I got the email and thought the
last comment was the latest :) Sorry about that.

Is there any way to match a newline?  <SEQ TYPE="NULL"
DELEGATE="PHP">&#xA;</SEQ> evidently doesn't work (neither
does "&#10;"--also wouldn't work for Macs where newline = "\r".

Scragz: confirmed.  The following code:


<?php
// if so, the following ?>will display as output


Outputs "will display as output" as expected.  Also, see the
second non-code paragraph here:

Ignore me, what I posted doesn't really work at all now that
I look closer.

I got pretty close with this:

<SPAN TYPE="COMMENT1" NO_LINE_BREAK="TRUE" EXCLUDE_MATCH="TRUE">
    <BEGIN>//</BEGIN>
    <END>?&gt;</END>
</SPAN>

The only thing I can't figure out is how to highlight the
BEGIN bit as a comment and not the END bit.

This caught my attention and I've been working on it for
over an hour, when I really should have been using jEdit for
real programming. :)

I ended up trying these additions to modes/php.xml:

<SEQ DELEGATE="PHP_LINECOMMENT">//</SEQ>
<SEQ DELEGATE="PHP_LINECOMMENT">#</SEQ>

<RULES SET="PHP_LINECOMMENT" DEFAULT="COMMENT1">
	<SEQ TYPE="NULL" DELEGATE="MAIN">?&gt;</SEQ>
	<SEQ TYPE="NULL" DELEGATE="PHP">&#xA;</SEQ>
</RULES>

(I hope those show up ok)

The idea is that a line comment will end at either a "?>" or
a newline, whichever comes first. However this didn't work.
The comments now end properly at PHP closing tags but fail
to end at newlines.

Any ideas? I've also been trying to think of a regexp that
would catch line comments and make them end at a "?>", but
no luck so far. Back to real work for now.

Confirming that PHP does stop parsing at a '?>' when it is
in a line comment. I suppose jEdit should reflect this, right?
