[Lxr-dev] lxr-0.3.1 does not allow version-name that contains the char, '_'

[Yi-Shin Li <yi...@si...>]

LXR version: 0.3.1

I use gentoo linux. Per its naming rule, I
got linux-2.4.21_rc8-gss in /usr/src

I can not use LXR-0.3.1 to cross reference it.

Reason:
The varexpand(), from file, $(INSTALLPREFIX)/http/lib/LXR/Config.pm,
only accept variables within /^([a-zA-Z0-9\.\-]*)$/. Therefore,
my "linux-2.4.21_rc8-gss" is filtered out.

I modified it by adding '_' and it works for me.

my revised varexpand() :
sub varexpand {
    my ($self, $exp) = @_;
    $exp =~ s{\$\{?(\w+)\}?}{
       $self->{variable}->{$1} =~ /^([a-zA-Z0-9\.\-_]*)$/ ? $1 : ''
       }ge;
    return($exp);
}
