bhushanQA has asked for the wisdom of the Perl Monks concerning the following question:

I am having below INI file 
[Voice_Digit]
BASIC_testcase.txt  # this is my test case name which i Need to dig ou
+t and store as variable

[download]
I tried using config::INIFiles module but no success since the INI file format is bit different. Need help how to read the same.

    So your ini file contains .txt filenames to other ini data or do you want to construct your data like so? 
    $DATA{"VOICE_DIGIT"} = "BASIC_testcase.txt";

    And then, can there be multiple entries? Tell us more about your format.

    #!/usr/bin/perl

use strict;
use warnings;
use Data::Dumper;

open(INFH, "<", "a.ini") or die $!;

my %INI;
my $HEADER = "_";
while(<INFH>){
  chomp;
  s/\s*#.*//;
  s/^\s+//;
  s/\s+$//;
  next unless $_;
  if(/^\[(\S+)\]$/){
    $HEADER = uc($1);
    next;
  }
  $INI{$HEADER} = $_;
}
close(INFH);

print Dumper(\%INI);

    [download]

    output:

    $VAR1 = {
          'Voice_Digit' => 'BASIC_testcase.txt'
        };

      Hi Thanks for the reply, My .ini file is 
      [Test_suit_name]
Testcase1.txt

      [download]
      Basically, this ini file have many test suits and under that many test cases I want to select the test cases based on test suits. Hope this clears.

        use strict;
use warnings;

open my $fh, '<', 'an.ini' or die "Failed to open an.ini for reading: 
+$! <$^E>\n";

my (%settings, $head);
while (chomp(my $line = <$fh>)) {
    if ($line =~ /^\s*\[([^\[\]]+)\]\s*$/) {
        $head = $1;
    }
    elsif ($line !~ /^\s*$/) {

        Building on SimonPratt's work:

        #!/usr/bin/perl
use strict;
use warnings;
use Getopt::Long;

my $VERBOSE;
my @TESTSUITES;
my %TESTCASES_hash;
my @TESTCASES;

GetOptions (
    "testsuite=s" => \@TESTSUITES,
    "verbose" => \$VERBOSE
);

# Often it is useful to allow comma-separated lists of values as well 
+as multiple occurrences of the options.
@TESTSUITES = split(/\s*,\s*/,join(',', @TESTSUITES));

open my $fh, '<', 'an.ini' or die "Failed to open an.ini for reading: 
+$! <$^E>\n";

my (%settings, $head);
while (chomp(my $line = <$fh>)) {
    if ($line =~ /^\s*\[([^\[\]]+)\]\s*$/) {
        $head = $1;
    }
    elsif ($line !~ /^\s*$/) {
        push @{$settings{$head}}, $line;
    }
}

close $fh;


for my $suite (@TESTSUITES){
    for my $test (@{$settings{$suite}}){
        $TESTCASES_hash{$test}++;
    }
}
@TESTCASES = sort keys %TESTCASES_hash;


use Data::Dumper; print Dumper \%settings; print Dumper \@TESTCASES;

for my $testcase (@TESTCASES){
    # now iterate through your testcases
}

        [download]

        Which would work like:

        ./an.pl -t Test_suit_name
./an.pl -t Test_suit_name -t AnotherTest_suit_name
./an.pl -t Test_suit_name,AnotherTest_suit_name

        [download]

        latter two are the same, multiple testsuites are merged to produce a bigger list of testcases.

        Hope this extra push in the back helps you...

    Hi bhushanQA,

    Reading from a config file is a common task. If you've come up with a format that is difficult to process, change it, to standard INI-format, or YAML, or something that one of the many existing tools can read with no modification.

    Change your format to a normal Windows-style ini file and you can use Config::Tiny:

    Config file contents: 

    VoiceDigit = BASIC_testcase.txt

[mySubSection]
foo = bar

    [download]
    Script: 
    use strict; use warnings; use feature 'say';
use Config::Tiny;

my $conf = Config::Tiny->read('1159584.ini');

say $conf->{_}->{'VoiceDigit'};
say $conf->{'mySubSection'}->{'foo'};

__END__

    [download]
    Output: 
    BASIC_testcase.txt
bar

    [download]

    Hope this helps!


    The way forward always starts with a minimal test.

      Looking at the grammar in the documentation, it doesn't seem to support values without the assignment operator.

      ini-file   = { <section> | <empty-line> }
 
empty-line = [ <space> ] <line-ending>
 
section        = <section-header> { <value-assignment> | <empty-line> 
+}
 
section-header = [ <space> ] "[" <section-name> "]" [ <space> ] <line-
+ending>
section-name   = string
 
value-assignment = [ <space> ] <property-name> [ <space> ]
                   "="
                   [ <space> ] <value> [ <space> ]
                   <line-ending>
property-name    = string-without-equals
value            = string

        Simple solution, subclass and "handle" it instead of throwing error
