[ jEdit-devel ] [jedit:bugs] #3005 syntax: does not allow matching of newlines

[Roman T. <tso...@us...>]

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.

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 "?>".
