Re^10: Processing CSV File

[Kenosis]

Give the following change a try:

open my $csvfh, '<:crlf', $csvFile or die "Unable to open $csvFile: $!
+";
                  ^
                  |
                  + - Add the :crlf

[Perl3r]

Same error as before..


Use of uninitialized value $vars in chomp at create-configs.pl line 18
+, <$csvfh> line 1.
Use of uninitialized value $vars in split at create-configs.pl line 19
+, <$csvfh> line 1.

OK... Instead of installing Text::CSV, you can download CSV.pm into the same directory as create-configs.pl. Here's the updated script that requires CSV.pm to parse the csv files:

#!/usr/bin/perl
#
use strict;
use warnings;
require 'CSV.pm';

$ARGV[0] or die "Usage: $0 <filename> [<filename>] ...";

my ( $template_file_name, $templateText, %hash ) = '';

my $csv = Text::CSV->new( { binary => 1, eol => $/ } )
  or die "Cannot use CSV: " . Text::CSV->error_diag();

for my $csvFile (@ARGV) {
    print "\nProcesing file $csvFile ...\n";
    open my $csvfh, '<', $csvFile or die "Unable to open $csvFile: $!"
+;

    # Ignore column names in first line
    my $columnNames = $csv->getline($csvfh);

    # Get vars from second line
    my @vars = @{ $csv->getline($csvfh) };

    # Process each csv line
    while ( my $row = $csv->getline($csvfh) ) {
        my $templateFN = pop @$row;

        if ( $template_file_name ne $templateFN ) {
            $template_file_name = $templateFN;
            undef $templateText;
        }
        
        # keys: fields from second line; values: fields from csv line
        @hash{@vars} = @$row;

        $templateText //= getTemplateText($template_file_name);
        my $templateTextCopy = $templateText;

        $templateTextCopy =~ s/$_/$hash{$_}/g for keys %hash;

        my $ofile_name = $hash{'##rtrname##'} . '.txt';

        print "Writing to file: $ofile_name\n";
        open my $fh, '>', $ofile_name or die "$ofile_name: $!";
        print $fh $templateTextCopy;
        close $fh;
    }

    close $csvfh;
}

print "\nDone!\n";

sub getTemplateText {
    my ($template_file_name) = @_;

    local $/;
    open my $fh, '<', $template_file_name or die "$template_file_name:
+ $!";
    $templateText = <$fh>;
    close $fh;

    return $templateText;
}

This workaround saves you from installing the Text::CSV Module.

[Tux]

• When using Text::CSV_XS or Text::CSV do not pass eol on parser objects when eol is withing default realms. That is all handled automatically.
• Then "<:crnl" will not be required at all.
• If needing CSV parsing and CSV writing, make twoCSV objects where only the writing object defines eol
• Use auto_diag!

# No eol and auto_diag > 1 will cause die's on error (with diagnostics
+)
my $csv = Text::CSV_XS->new ({ binary => 1, auto_diag => 2 });

I get the following error

Can't locate Text/CSV_PP.pm in @INC (@INC contains: /Library/Perl/5.12/darwin-thread-multi-2level ....
I did the same thing for the CSV_PP.pm, as was done for the CSV.pm.. ie downloaded the code, and created a CSV_PP.pm in the same directory..
Though no joy there..
Any other ideas?
Thanks
