bgcolor problem

[Ryan Golhar]

I'm using Gbrowse2, v1.9971.  I'm trying to customize the bgcolor for
one of my tracks using something like this:

bgcolor         = sub {
                     my %colors = (0 => '#000099');
                     return $colors{0};
                 }


However, this code keeps giving the error:
[error] An error occurred while evaluating the callback at
section='Castellana_AtPeptide', option='bgcolor':, referer:
http://localhost/gb2/gbrowse/arabidopsis/
[error]     => Can't find string terminator "'" anywhere before EOF at
(eval 112) line 1., referer: http://localhost/gb2/gbrowse/arabidopsis/
[error]   at
/usr/lib64/perl5/site_perl/5.8.8/x86_64-linux-thread-multi/Bio/Graphics/Browser.pm
line 246, referer: http://localhost/gb2/gbrowse/arabidopsis/

I've determined it has something to do with the single-tick quotes.  I
tried different ways to get around this but am constantly getting
different errors.  Is this a problem with my code, or is this something
with Gbrowse that I'm not aware of?

Hi Ryan,

The error is a result of gbrowse interpreting the '#' character as
a comment even though you are using valid perl code.  The way to
solve this is to make the '#' character using the 'chr' function:

                       my $hash = chr35);
                       my %colors = (0 => ${hash}000099");
