Following up on a discussion on the GeSHi-devel mailing list I got some interesting testcases for testing Perl in all its oddity<\/a>.<\/p>\n

So lets get things startet: Open up the testcase, and see: The CSS is not fully precise on some stuff (some classes in GeSHi can be used for different things like .co5 for perl is used for predefined variables). So I did a quick editing of the CSS stylesheet with the Web Developer Toolbar to mark everything that was of specific classes (as expected) in a different color than white to see if it actually is highlighted (which most stuff was). <\/p>\n

Adding the missing stuff into the language file I got an updated version for Perl that can be found as revision 1975 in the GeSHi SVN repository for testing. Things I didn’t include there are file descriptors as they should already be highlighted (even if <> and <test> are marked as different things.<\/p>\n

But in one thing the testcase wasn’t right: Heredocs As well as Regular expressions are supported by GeSHi, see:<\/p>\n

$test = <<HEREIAM;\r\nSome text to show this is a heredoc part\r\nHEREIAM;\r\n$match =~ \/te[sx]t\/g;\r\n$replace =~ s\/x\/s\/i;<\/pre>\n
Just to be complete on this. Oh, and the <\/p>\n
< <<\/pre>\n
 bug is a problem with my WordPress. The demo page<\/a> does the Heredoc correctly, for those that don’t believe me \ud83d\ude09<\/p>\n
Now I’m only lacking this little testcase as a file for inclusion into the Code Repository of GeSHi and I can declare this „done“ …<\/p>\n
Update:<\/b> Revision 1977 contains some important updates on the rev1975\\r1974 version of this file: I missed some things due to some issue I had with encoding $ inside of regexps (I missed the escapes PHP needed inside the string). I also added the few remaining cases that the previous version didn’t yet.<\/p>\n
What will not be highlighted correctly are bacreferences to numbers (and I thought C was odd …) and nested Heredocs (i.e. Heredocs with two or more starters on one line).<\/p>\n
But given the current state this should somewhat resemble most of what even most insane Perl programmers need when puking their code …<\/p>\n
