In a university lab we were given this piece of code: #!/usr/bin/perl use strict; use warnings; use Text::CSV; my $file = $ARGV[0]; my $csv = Text::CSV->new(); open (CSV, $file) or die $!; my @fields; while ( my $record = <CSV>) { if ( $csv->parse($record) ) { @fields = $csv->fields(); print "$fields[0] $fields[1] $fields[2] \n"; } else { my $err = $csv->error_input; print "Failed to parse line: $err"; } } close CSV; my issue is this is the first time i had ever used perl and we were asked to modify the code. Can i please have this piece of code explained line by line. I know in general what the lines do but not the details of how to use them. I also know that the program is supposed to parse a CSV file. I am using windows to do this, using "Context" to check notation and notepad to program so there will be no errors when it is transfered to a mac. Thank you for any help you can give me. |

Well, there's a first time for most things. Welcome to University! Your complementary copy of Perl documentation is available at http://perldoc.perl.org/ Your friendly TAs likely have their office hours posted on the course webpage, and will probably steer you in the direction of the intention of the assignment. |
