Re: What's the best way to convert a non interpolated single-quoted string into an interpolated double-quoted string?

I that situation I use place holder text that is replaced at run time using a regex and a hash lookup. Something like the following:

my %subs = (home => 'HomePathFromConfigOrEnv');
my $keyMatch = join '|', keys %subs;
my $cfgStr = '!home!/path';

$cfgStr =~ s/!($keyMatch)!/$subs{$1}/g;
print $cfgStr;

Prints:

HomePathFromConfigOrEnv/path

True laziness is hard work
