NAME

ConfigFile - Parse a simple configuration file

SYNOPSIS

use ConfigFile;

my $config_hash = ConfigFile::read_config_file($configuration_file);

NOTES

In versions up to 1.0, the function read_config_file was exported to the calling program's namespace - Starting in version 1.1, nothing is exported by default. You can either fully qualify read_config_file or explicitly import it into your namespace:

Fully qualifying read_config_file

  use ConfigFile;
  my $config_hash = ConfigFile::read_config_file($configuration_file);

Explicitly importing read_config_file

  use ConfigFile qw(read_config_file);
  my $config_hash = read_config_file($configuration_file);

DESCRIPTION

"read_config_file" parses a simple configuration file and stores its values in an anonymous hash reference. The syntax of the configuration file is quite simple:

    # This is a comment
    VALUE_ONE = foo
    VALUE_TWO = $VALUE_ONE/bar
    VALUE_THREE = The value contains a \# (hash). # This is a comment.

Options can be clustered when creating groups:

    CLUSTER_ONE[data] = data cluster one
    CLUSTER_ONE[value] = value cluster one
    CLUSTER_TWO[data] = data cluster two
    CLUSTER_TWO[value] = value cluster two

Then values can be fetched using this syntax:

    $hash_config->{CLUSTER_ONE}{data};

There can be as many sub-options in a cluster as needed.

    BIG_CLUSTER[part1][part2][part3] = data

is fetched by:
$hash_config->{BIG_CLUSTER}{part1}{part2}{part3};

The only restriction is no space in the key part of the line.

    CLUSTER_ONE[data] = data cluster one      # Right
    CLUSTER_ONE[ data ] = data cluster one    # Wrong

Function "read_config_file"

Syntax
