App::SimpleScan::Substitution::Line 2.02

App::SimpleScan::Substitution::Line is a line with optional fixed variable values.

SYNOPSIS

my $line =
App::SimpleScan::Substitution::Line->new(" this ");

# Use only this value when substituting " ".
$line->fix(substituite => change);

# what vars are fixed?
my @fixed_ones = $line->fixed();

# Forget about 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.
