I'm writing some code that generates HTML pages from templates. I'd been prototyping the system with here documents, when I got the wacky idea that I might put the here doc text in a file, slurp it into a string, and have a cheap template. I probably will go with one of the excellent \w+::Template modules, but first I want to play with the idea of "templates on the cheap."

What I want, basically, is double-quote interpolation of variable contents, as the text files I have contain lines of the form 

<a href='mailto: $maintainer'>Send email</a> to site maintainer.

my idea so far: 

use strict;
my $maintainer = 'root@god.com'; # I've also tried making this a globa
+l, so I don't think it's scoping
my $data;
{
    local $/;
    open FILE, "filename" or die "ha ha! :$!\n";
    $data = <FILE>;
    close FILE;
}

[download]

But that leaves $data</a> as is (i.e. with a literal <code>$maintainer in it.

Out of (at this point) pure curiosity, how would I get the value of $maintainer to interpolate in there? (I've tried variations on eval and here-doc quoting, including the too-good-to-have-worked-anyhow $data = "$data"; with no sucess).

Philosophy can be made out of anything. Or less -- Jerry A. Fodor
