Bug #30937 for Test-File-Contents: Test::File::Contents suggestion

Hi, (This email complete, hit the send key by mistake previously) Nice file testing module. I've been using a hand rolled function filtered_compare_files() for years. You might like to add something like this to your module. Basically it does an exact file comparison but allows you to pass a filtering function so that things like dates and such can be replaced with YYYYMMDD for example so that the comparisons ignore the date the test plan was run. Perhaps: file_contents_filtered( $file1, $file2, $rcFilterSub, $test_description); Example usage file_contents_filtered( 'got.txt', 'expected.txt', sub { my ($contents) = @ARG; $contents =~ s{\d\d\d\d - \d\d - \d\d}{YYYY-MM-DD}xmsg; $contents =~ s{\w+ \@ \w+}{USER\@HOST}xmsg; return $contents; }, 'compare files ignoring dates and hostnames' ); The function loads the contents of each file into memory, uses the code ref passed in to transform each then does an 'eq' comparison for identicalness.
