This is just like ReadLine regexp quicktest except it tests a string for substitutions. You can screw it up just as in your own perl code! Again, if you have an instance where this doesn't hold true comment. To be clear:

  • string: give a string to be substituted from
  • replace: give a regexp pattern to replace
  • with: give a string to replace regexp pattern
  • suffix: something to follow the last "/", eg. smx

    And all the while you can shuffle up and down using the ReadLine command history...
    • #!/usr/bin/perl -w
use strict;

use Term::ReadLine;
# for correction and command history you must have
# Term::ReadLine::Gnu (from CPAN) installed

my $term = new Term::ReadLine 'regexp Smode';
my $pr1 = "string: "; my $pr2 = "replace: "; 
my $pr3 = "with: "; my $pr4= "suffix: ";
my $OUT = $term -> OUT || *STDOUT;
my $output;

while (1) {
        my $string = $term -> readline($pr1);
        my $replace = $term->readline($pr2);
        my $with = $term->readline($pr3);
        my $suffix = $term->readline($pr4);
        eval{ eval "(\$output = \$string) =~ s/\$replace/\$with/$suffi
+x" };
        print $OUT "$output\n";
}
