[gedit-list] Syntax coloring bug with perl

There is a problem with syntax coloring for perl. I'm now on the most recent ubuntu 8 distribution of gedit which is 2.24.2.

It appears that the << operator for "shift left" is being confused with the << redirection that introduces a HERE document inside of perl. The result it that << starts a block of text that continues until the next blank line which I believe is sensed as the end of block that follows a line like

$seed = $seed << 2;

I expect the variable $seed to be shifted left two bits and that happens OK. It's the coloring that is all messed up until a blank, not a comment, line is found. (That's likely because there is no text after the << other than the trailing ;)

I had a look at /usr/share/gtksourceview-2.0/language-specs/perl.lang and there are two places where "&lt;&lt;" appears and they correspond to the shift operator and the HERE redirector. I sort of believe that the problem is an insufficiently precise regular expression describing the redirector syntax in this line.


But programming by experiment is at best dangerous and I need some answers to keep me out of trouble:

1. Is the XML file that is perl.lang documented anywhere? Is it part of gedit or some other operation? It does not seem to reside in a location owned by gedit.

2. Are the regular expressions precisely the same as those in perl's Camel Book? If not where are they documented?

3. I can't compile gedit yet on my 64 bit ubuntu box but I can read code. Can I have a pointer to the source file that reads the perl.lang file? It is part of gedit or is it really part of the Gtk? Has anything changed in 2.26 that relates to this problem?

4. When is perl.lang read? Can I keep gedit running while I use gedit itself to edit the language file and test in another window?

5. Is there a place where I can find a structured list of dependencies that will help me prepare ubuntu for compiling gedit on my 64 bit machine? The errors go by so fast that I just can't seem to get everything I need and one-at-a-time builds are not getting me there.
