App::SimpleScan::Substitution::Line - a line with optional fixed variable values
my $line = App::SimpleScan::Substitution::Line->new("<substitute> this <too>"); # Use only this value when substituting "<substitute>". $line->fix('substituite' => 'change'); # what vars are fixed? my @fixed_ones = $line->fixed(); # Forget about <substitute> now. $line->unfix('substitute'); # Forget all fixed variables. $line->no_fixed # Get the line back as a string. print "$line";
App::SimpleScan::Substitution::Line allows us to associate fixed substitution values with a specific string. This allows us to re-substituted the same value if, during string substitution, we find the variable reappearing as the result of substituting some other variable. This eliminates the "cross-product" bug that appeared in some complex nest substitions.
