Perl syntax highlighting
Hello London Perl Mongers,
What do people reckon to use when wanting to do Perl syntax highlighting
(Perl ? HTML), such as one might want to use in one's source code
repository browser.
There is an existing repository browser installation at $employer which
does Perl syntax highlighting, but I've found the existing highlighter
to be a bit mediocre in as much as it doesn't handle some rather common
cases. The people who look after the repository browser have been
working on improving the syntax highlighter, and have so far managed to fix:
* a single quote in POD apparently being interpreted as the start of a
string literal
* a single quote in a comment apparently being interpreted as the start
of a string literal
but I am still suffering from
* a single quote in q{...} string apparently being interpreted as the
start of a string literal
So I was wondering if there was a known good Perl syntax highligher. All
suggestions gratefully received; suggestions of the form FooHighLight
version = 2.71828 score bonus points.
(Before you ask, I don't (yet) know what syntax highligher is being used
at the minute.)
Regards,
Bill

All suggestions gratefully received; suggestions of the form FooHighLight version = 2.71828 score bonus points. I don't know about known good, but here's what I use in various places. On blogs.perl.org (Movable Type) we use a GCPrettify plugin[1] which is a wrapper around prettify.js[2]. On Perlhacks[3] (Wordpress), I use a plugin called Syntax Highlighter for WordPress[4] which is a wrapper around SyntaxHighlighter[5]. On my code web site[6] I use something I hacked together using PPI::HTML[7]. I should see if enough of that is useful enough to publish it somewhere. I'm not sure if any of these solutions fix your specific issues. Cheers, Dave...

As a Vim user, I like Text::VimColor. This actually delegates the
highlighting to Vim, meaning that the colours output exactly match those
in my editor.
* a single quote in POD apparently being interpreted as the start of a
string literal
* a single quote in a comment apparently being interpreted as the
start of a string literal
* a single quote in q{...} string apparently being interpreted as the
start of a string literal
Vim gets all of those correct.

I'm tempted to suggest that we're generally likely to have a high concentration of people who know other people who have come to London and stayed in hotels, and can perhaps therefore pass on grumbles or praise about them. But a quick ask around reveals that I don't know anybody who would recommend a hotel in London so perhaps that's not such a solidly-founded suggestion after all. -- Avi

Re: Perl syntax highlighting
I built a web-based tool around Perl::Critic for my employer, and for
syntax-coloring I used PPI::HTML. I have yet to see it get confused by
anything, and it has had to chew through some pretty atrocious Perl code...
https://metacpan.org/module/PPI::HTML
I don't remember all the details off-hand, and I can't share the code
unfortunately. But tomorrow when I'm back in my office I might look it
over and see if I can relate a few helpful hints.
I can get away with posting this small snippet:
my $document = PPI::Document-new($sourcefile);
my $ppi_html = PPI::HTML-new(line_numbers = 1);
my @lines = split /br\n/, $ppi_html-html($document);
# Now strip the line-numbers PPI provided, and force-close the span on
# each line. This seems wasteful, but it was the only way to get PPI::HTML
# to markup the code on a line-by-line basis, as opposed to leaving spans
# open across whole blocks of lines.
for my $lineno (0 .. $#lines) {
if ($lines[$lineno] =~ s{^/span}{}) {
$lines[$lineno - 1] .= '/span';
}
$lines[$lineno] =~ s{span\s+class=line_number\s*\d+:\s+/span}{}x;
}
Basically, I needed individual lines as opposed to just a big chunk of
HTML (each line goes into a table row, with some other information in
other td's of that same row). Calling PPI::HTML-new() with
line_numbers = 1 prevents PPI::HTML from spanning mark-up across
lines. For example, a 5-line comments would have the starting span on
the first line, but the closing /span on the 5th line. I needed each
line to be marked up individually. line_numbers does this as a
side-effect of having to insert a span for each line number.
But I didn't want their line numbers :-). Plus, they close whatever
currently-open span there is at the start of the next line instead of
on the line they opened it. So in the for-loop, I first excise the
leading /span, and if there was one to excise (there isn't on the
first line, of course) I append it to the previous line. Now each line
is truly self-contained. I then delete the leading span that matches
'span\s+class=line_number\s*\d+:\s+/span', which drops their line
numbering.
And I now have @lines, which are my marked-up, syntax-highlighted
(highlit?) lines.
Of course, if you don't need individual lines, you can skip all of the
extra work:
my $document = PPI::Document-new($sourcefile);
my $ppi_html = PPI::HTML-new();
my $html = $ppi_html-html($document);
And you can decide for yourself if you need line numbers or not...
