See Config::Simple or search Config `print pack("A25",pack("V*",map{1919242272+$_}(34481450,-49737472,6228,0,-285028276,6979,-1380265972)))`	[reply] [d/l]

I also find Config::Wrest pretty useful, plus it comes from the BBC, though i realise this isn't much of a plaudit for non-brits... Just a something something...	[reply]

If you're looking to use a fairly standard formatted config file (rather than one with "my" variables), but instead something along the lines of `[mysection] somevar = value` [download] You might try Config::IniFiles `use Config::IniFiles; my $config_data = new Config::IniFiles( -file => $config_file ) or die +("Cannot read $config_file"); $myvar = $config_data->val('mysection', 'somevar', 'defaultvalue');` [download]	[reply] [d/l] [select]

Good news: require can be used to read such a file Bad news: my (lexical) variables will not be inherited by the caller. Use package variables, see our.	[reply]

even worse news, that file is not valid perl, so that won't work.	[reply]

Cange your config file to a module - eg. `package MyApp::Config; our $a = 1000; our $b = "test"; our $c = 2000; our $d = "test2"; 1;` [download] Then you can load it with `use MyApp::Config;` and access variables in following way `$MyApp::Config::c`.	[reply] [d/l] [select]

Really worse old news: `require`ing configuration files opens a gapping security hole. Don't do that! Alexander -- Today I will gladly share my knowledge and experience, for there are no sweeter words than "I told you so". ;-)	[reply] [d/l]

I've found ConfigReader::Simple to be useful for me.	[reply]
