IniHash(3) User Contributed Perl Documentation IniHash(3)NAMEConfig::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().
