Config::File 1.4

Config::File is a Perl module to parse a simple configuration file.

SYNOPSIS

use Config::File;
my $config_hash = Config::File::read_config_file($configuration_file);

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: $hash_config->{BIG_CLUSTER}{part1}{part2}{part3};
There are a couple of restrictions as for the names of the keys. First of all, all the characters should be alphabetic, numeric, underscores or hyphens, with square brackets allowed for the clustering. That is, the keys should conform to /^[A-Za-z0-9_-]+$/

This means also that no space is allowed in the key part of the line.

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