Re: How can one re-parse(?) a string to fill in variables

These days, why not just use double-quotes to interpolate the string. #!/usr/bin/perl -w use strict; my $name = 'Alex'; my $greeting = "Hello $name"; print $greeting

If you read the string `$greeting` from a file, how will interpolation work? Basically, this question leads to a templating system, of which there are lots in Perl, from Interpolation over Text::Template to Template Toolkit. Depending on your output needs, there are other modules, like Email::Template and HTML::Template::Compiled.	[reply] [d/l]
