#3005 syntax: does not allow matching of newlines

[daniel hahler]

In jEdit mode files, the following does not work:
<SEQ_REGEXP DELEGATE="FOO">\n</SEQ_REGEXP>

Likewise, the following does not include newlines:
<SEQ_REGEXP DELEGATE="FOO">\s</SEQ_REGEXP>

This would allow to fix bug 958013, so that a PHP line comment could either on "\n" or "?>".

+1 vote for fixing this.
The PHP line comment problem is very annoying.

\n support does not seem to be necessary as SEQ (SEQ_REGEXP) is only applied to a single line i.e.
until \n. And this is why \s does not "include" newlines here.

A fix to the bug will follow (new URL https://sourceforge.net/p/jedit/bugs/2106/).

I did probably wrong closing the ticket.

Now I am trying to implement multiline strings in C mode (https://sourceforge.net/p/jedit/bugs/2935/)

I delegated the string SPAN to a separate rule:

<rules set="STRING_LITERAL" default="LITERAL1" escape="\">
<seq_regexp delegate="MAIN"><![CDATA[[^\]$]]></seq_regexp>
</rules>

... so that EOL without backslash should trigger fallback to MAIN. But when I try to use negative lookbehind assertion (instead of [^\] which improperly includes the token) nothing works.

Seems like EOL does not match by itself but with something else. Thus, [^\]$ matches but (?<!\)$ does not.

This needs further investigation.
