my $config_hash = Config::File::read_config_file($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 as follows:
# This is a comment VALUE_ONE = foo VALUE_TWO = $VALUE_ONE/bar VALUE_THREE = The value contains a \# (hash). # This is a comment.
Options can be clustered when creating groups:
CLUSTER_ONE[data] = data cluster one CLUSTER_ONE[value] = value cluster one CLUSTER_TWO[data] = data cluster two CLUSTER_TWO[value] = value cluster two
Then values can be fetched using this syntax:
There can be as many sub-options in a cluster as needed.
BIG_CLUSTER[part1][part2][part3] = data
is fetched by:
There are a couple of restrictions as for the names of the keys. First of all, all the characters should be alphabetic, numeric, underscores or hyphens, with square brackets allowed for the clustering. That is, the keys should conform to /^[A-Za-z0-9_-]+$/
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
Arguments$file is the configuration file.
Return valueThis function returns a hash reference. Each key of the hash is a value defined in the configuration file.
Description"read_config_file" parses a configuration file a sets up some values in a hash reference.
Function not exported by defaultIn 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 Config::File; my $config_hash = Config::File::read_config_file($configuration_file);
- Explicitly importing read_config_file
use Config::File qw(read_config_file); my $config_hash = read_config_file($configuration_file);
Migrated away from ConfigFile into Config::FileAs of version 1.4, in order to include this module in the CPAN, I decided to move away from the highly unstandard name of ConfigFile and rename the module to Config::File. A small redirecting module is put in place, so current code using this module does not break, but the ConfigFile namespace usage is deprecated (and will thus issue a warning). Please update your code!
