Inverting Template::Toolkit

talexb has asked for the wisdom of the Perl Monks concerning the following question:

I'm in a situation where I'd like to be able to use a Template::Toolkit file (the template, with variables where the data will go) and a populated file and go backwards to get a hash of variables that contain the corresponding values.

That is, if I have a template

directory: [%- foobar -%]
[download]

and a config file

directory: /home/alpha/beta
[download]

then eventually I'll have

$variables{'foobar'} = '/home/alpha/beta';
[download]

Hmmm .. I do have conditionals in my file, so this may be a tough nut to crack .. let me tinker a bit. But if you have ideas, feel free!

Did you look at Template::Extract?	[reply]

From the CPAN notes: This document describes version 0.39 of Template::Extract, released July 15, 2005. Wow. That's fresh software. Thanks! I'll try it out. Alex / talexb / Toronto "Groklaw is the open-source mentality applied to legal research" ~ Linus Torvalds	[reply]

There's actually a "holy trinity" of modules: Template: template + data => document Template::Extract: template + document => data Template::Generate: document + data => template -- <http://www.dave.org.uk> "The first rule of Perl club is you do not talk about Perl club." -- Chip Salzenberg	[reply]

Wow that's impressive. If you'd combine the generate and extract modules, you could get the data from a template-driven site.	[reply]
