NAME
App::SimpleScan::Substitution::Line - a line with optional fixed variable values
SYNOPSIS
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";DESCRIPTION
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.
