Escapes and comments in Config::General

John M. Dlugosz has asked for the wisdom of the Perl Monks concerning the following question:

I had a line in my conf file that was something like:
foo 16′ roll
and when I read it in I got “16&”. Ah, the # starts a comment. So I changed it to
foo 16&\#x2032; roll
And now I get “16&\#2320 roll” !

The backslash stopped the # from being a comment, but the slash itself was also in the string!

There is an example of this in the manual, so it is clearly supposed to work that way.

I just can't win today <sigh>. What's going on here?

I can't reproduce your stated result; I don't see a backslash in the string. I am using Config::General version 2.50 which I just downloaded from CPAN: `$ cat rcfile foo 16&\#x2032; roll $ $ cat 894796.pl #!/usr/bin/env perl use warnings; use strict; use Config::General; my $conf = Config::General->new('rcfile'); my %config = $conf->getall(); print $config{foo}, "\n"; $ ./894796.pl 16′ roll $` [download]	[reply] [d/l]

OK, I updated to 2.5 (from 2.48) and it works fine! I see something about "missing a #" in some other bug fix, in the change log. Thanks for mentioning the latest version detail in your post. —John	[reply]

My code that reads the file: `method fetch { if (!defined($data) \|\| (my $age= -M $conffilename)) { # must (re)load the file my $conf= new Config::General:: (-ConfigFile => $conffilename, -UT +F8 => 1); my %result= $conf->getall; $data= \%result; $fileage= $age; } return $data; }` [download] This is a Catalyst "Model", and the resulting hash winds up in a stash passed to Template::Alloy. `<p>[% sp.priceline %]</p>` [download] etc.	[reply] [d/l] [select]
