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


       Version 3.00.05


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


       This module reads and writes INI files.


               $hashreference = ReadINI ($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.

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

       The available options are:

           - controls whether the module supports the heredoc syntax :

                   many lines
                   long value

                   0 : heredocs are ignored, $data->{section}{name} will be '<<END'
                   1 : heredocs are supported, $data->{section}{name} will be "the\nmany lines\nlong value"
                           The Perl-lie extensions of name=<<"END" and <<'END' are not supported!
                   'Perl' : heredocs are supported, $data->{section}{name} will be "the\nmany lines\nlong value"
                           The Perl-lie extensions of name=<<"END" and <<'END' are supported.
                           The <<'END' never interpolates %variables%, the "END" always interpolates variables,
                           unlike in other values, the %variables% that are not defined do not stay in the string!

           Default: 0 = OFF

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

             leads to
                   $data->{section}->{name} = "Jenda"

                   systemvars = 1  - yes, take values from %ENV
                   systemvars = \%hash     - yes, take values from %hash
                   systemvars = 0  - no

           - 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 (tied)
             lower - the hash will be case insensitive, all keys are made lowercase (tied)
             upper - the hash will be case insensitive, all keys are made uppercase (tied)

           - controls whether the created section hashes support defaults. See

           - allows you to specify the class into which to tie the created hashes. This option
           overwrites the "case" and "withdefaults" options!

           You may for example use

             class => 'Tie::IxHash',

           to store the sections in hashes that remember the insertion order.

           - 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'];

           - if set to an array ref, then the list will be stored in that array, and no
           $config->{'__SECTIONS__'} is created. The case of the section names stored in this
           array is controled by the "case" option even in case you specify the "class".

           - 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.

           - 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.

           - 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:


           The default is


           - the IO layer(s) to use when opening the file. See perldoc "perlopen".

           If the file is in UTF8 and starts with a BOM it will be automatically opened in UTF8
           mode and the BOM will be stripped.  If it doesn't start with the BOM you have to
           specify the utf8 layer!

       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.


         AddDefaults( $config, 'normal section name', 'default section name');
         AddDefaults( $config, 'normal section name', \%defaults);

       This subroutine adds a some default values into a section. The values are NOT copied into
       the section, but rather the section knows to look up the missing options in the default
       section or hash.


         if (exists $config->{':default'}) {
               foreach my $section (keys %$config) {
                 next if $section =~ /^:/;
                 AddDefaults( $config, $section, ':default');


         $hashreference = ReadSection ($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 ($filename, $hashreference)

       Writes the hash of hashes to a file.


       The same as WriteINI().
