Config::IniHash.3pm

NAME

Config::IniHash - Perl extension for reading and writing INI files

version 3.00.00

SYNOPSIS

   use Config::IniHash;
   $Config = ReadINI 'c:\some\file.ini';
 
 

DESCRIPTION

This module reads and writes INI files.

Functions

ReadINI

         $hashreference = ReadINI ($filename, %options)
         $hashreference = ReadINI (\$data, %options)
         $hashreference = ReadINI (\@data, %options)
         $hashreference = ReadINI ($filehandle, %options)
 
 

The returned hash contains a reference to a hash for each section of the INI.

     [section]
     name=value
   leads to
     $hash->{section}->{name}  = value;
 
 

The available options are:

heredoc

- controls whether the module supports the heredoc syntax :

         name=<<END
         the
         many lines
         long value
         END
         othername=value
 
 

Default: 0 = OFF

systemvars

- controls whether the (system) variables enclosed in %% are interpolated and optionaly contains the values in a hash ref.

     name=%USERNAME%
   leads to
     $data->{section}->{name} = "Jenda"
 
         systemvars = 1  - yes, take values from %ENV
         systemvars = \%hash     - yes, take values from %hash
         systemvars = 0  - no
 
 

case

- controls whether the created hash is case insensitive. The possible values are

   sensitive     - the hash will be case sensitive
   tolower       - the hash will be case sensitive, all keys are made lowercase
   toupper       - the hash will be case sensitive, all keys are made uppercase
   preserve      - the hash will be case insensitive, the case is preserved
   lower - the hash will be case insensitive, all keys are made lowercase
   upper - the hash will be case insensitive, all keys are made uppercase
 
 

withdefaults

- controls whether the created section hashes support defaults.

sectionorder

- if set to a true value then created hash will contain

         $config->{'__SECTIONS__'} = [ 'the', 'names', 'of', 'the', 'sections', 'in', 'the',
                 'order', 'they', 'were', 'specified', 'in', 'the', 'INI file'];
 
 

allow_multiple

- if set to a true scalar value then multiple items with the same names in a section do not overwrite each other, but result in an array of the values.

- if set to a hash of hashes (or hash of arrays or hash of comma separated item names) specifies what items in what sections will end up as hashes containing the list of values. All the specified items will be arrays, even if there is just a single value. To affect the items in all sections use section name '*'.

By default false.

forValue

- allows you to install a callback that will be called for each value as soon as it is read but before it is stored in the hash. The function is called like this:

   $value = $forValue->($name, $value, $sectionname, $INIhashref);
 
 

If the callback returns an undef, the value will not be stored.

comment

- regular expression used to identify comments or a string containing the list of characters starting a comment. Each line is tested against the regexp is ignored if matches. If you specify a string a regexp like this will be created:

         qr/^\s*[the_list]/
 
 

The default is

         qr/^\s*[#;]
 
 

You may also set the defaults for the options by modifying the $Config::IniHash::optionname variables. These default settings will be used if you do not specify the option in the ReadINI() or ReadSection() call.

ReadSection

   $hashreference = ReadSection ($string)
 
 

This function parses a string as if it was a section of an INI file and creates a hash with the values. It accepts the same options as ReadINI.

WriteINI

   WriteINI ($filename, $hashreference)
 
 

Writes the hash of hashes to a file.

PrintINI

The same as WriteINI().
