Thanks. Following I am providing ReadCSV.pm, parameters.csv and getvalue.pl. It is working fine but I want to avoid any comments (starts with #) in parameters.csv and also any blank lines. How can I do that in ReadCSV.pm ?
ReadCSV.pm
package ReadCSV;
use strict;
use warnings;
use Data::Dumper;
use Text::CSV_XS;
use IO::File;
# Implementation:
sub csv_file_hashref {
my ($filename) = @_;
my $csv_fh = IO::File->new($filename, 'r');
my $csv = Text::CSV_XS->new ();
my %output_hash;
while(my $colref = $csv->getline ($csv_fh))
{
$output_hash{shift @{$colref}} = $colref;
}
return \%output_hash;
}
1;
parameters.conf
abc xyz,10
xyz pqr,2
pqr stq,0.1
getvalue.pl
use strict;
use warnings;
use Data::Dumper;
use ReadCSV;
my $hash_ref = ReadCSV::csv_file_hashref('parameters.conf');
foreach my $key (sort keys %{$hash_ref}){
print qq{$key:};
print join q{,}, @{$hash_ref->{$key}};
print qq{\n};
}

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
