=head1 NAME

Config::IniFiles - A module for reading .ini-style configuration files.

=head1 SYNOPSIS

  use Config::IniFiles;
  my $cfg = Config::IniFiles->new( -file => "/path/configfile.ini" );
  print "The value is " . $cfg->val( 'Section', 'Parameter' ) . "."
    if $cfg->val( 'Section', 'Parameter' );

=head1 DESCRIPTION

Config::IniFiles provides a way to have readable configuration files outside
your Perl script. Configurations can be imported (inherited, stacked,...),
sections can be grouped, and settings can be accessed from a tied hash.

=head1 FILE FORMAT

INI files consist of a number of sections, each preceded with the
section name in square brackets, followed by parameter names and
their values.

  [a section]
  Parameter=Value

  [section 2]
  AnotherParameter=Some value
  Setting=Something else
  Parameter=Different scope than the one in the first section

The first non-blank character of the line indicating a section must
be a left bracket and the last non-blank character of a line indicating
a section must be a right bracket. The characters making up the section
name can be any symbols at all. However section names must be unique.

Parameters are specified in each section as Name=Value.  Any spaces
around the equals sign will be ignored, and the value extends to the
end of the line (including any whitespace at the end of the line.
Parameter names are localized to the namespace of the section, but must
be unique within a section.

Both the hash mark (#) and the semicolon (;) are comment characters.
by default (this can be changed by configuration). Lines that begin with
either of these characters will be ignored. Any amount of whitespace may
precede the comment character.

Multi-line or multi-valued parameters may also be defined ala UNIX
"here document" syntax:

  Parameter=<<EOT
  value/line 1
  value/line 2
  EOT

You may use any string you want in place of "EOT". Note that whatever
follows the "<<" and what appears at the end of the text MUST match
exactly, including any trailing whitespace.

Alternately, as a configuration option (default is off), continuation
lines can be allowed:

  [Section]
  Parameter=this parameter \
    spreads across \
    a few lines


=head1 USAGE -- Object Interface

Get a new Config::IniFiles object with the I<new> method:

  $cfg = Config::IniFiles->new( -file => "/path/config_file.ini" );
  $cfg = new Config::IniFiles -file => "/path/config_file.ini";

Optional named parameters may be specified after the configuration
file name. See the I<new> in the B<METHODS> section, below.

Values from the config file are fetched with the val method:

  $value = $cfg->val('Section', 'Parameter');

If you want a multi-line/value field returned as an array, just
specify an array as the receiver:

  @values = $cfg->val('Section', 'Parameter');

=head1 METHODS

=head2 new ( [-option=>value ...] )

Returns a new configuration object (or "undef" if the configuration
file has an error, in which case check the global C<@Config::IniFiles::errors>
array for reasons why). One Config::IniFiles object is required per configuration
file. The following named parameters are available:

=over 10


=item I<-file>  filename

Specifies a file to load the parameters from. This 'file' may actually be
any of the following things:

  1) the pathname of a file

    $cfg = Config::IniFiles->new( -file => "/path/to/config_file.ini" );

  2) a simple filehandle

    $cfg = Config::IniFiles->new( -file => STDIN );

  3) a filehandle glob

    open( CONFIG, "/path/to/config_file.ini" );
    $cfg = Config::IniFiles->new( -file => *CONFIG );

  4) a reference to a glob

    open( CONFIG, "/path/to/config_file.ini" );
    $cfg = Config::IniFiles->new( -file => \*CONFIG );

  5) an IO::File object

    $io = IO::File->new( "/path/to/config_file.ini" );
    $cfg = Config::IniFiles->new( -file => $io );

  or

    open my $fh, '<', "/path/to/config_file.ini" or die $!;
    $cfg = Config::IniFiles->new( -file => $fh );

  6) A reference to a scalar (requires newer versions of IO::Scalar)

    $ini_file_contents = <<EOT
    [section name]
    Parameter=A value
    Setting=Another value
    EOT

    $cfg = Config::IniFiles->new( -file => \$ini_file_contents );


If this option is not specified, (i.e. you are creating a config file from scratch)
you must specify a target file using L<SetFileName> in order to save the parameters.


=item I<-default> section

Specifies a section to be used for default values. For example, in the
following configuration file, if you look up the "permissions" parameter
in the "joe" section, there is none.

   [all]
   permissions=Nothing

   [jane]
   name=Jane
   permissions=Open files

   [joe]
   name=Joseph

If you create your Config::IniFiles object with a default section of "all" like this:

   $cfg = Config::IniFiles->new( -file => "file.ini", -default => "all" );

Then requsting a value for a "permissions" in the [joe] section will
check for a value from [all] before returning undef.

   $permissions = $cfg->val( "joe", "permissions");   // returns "Nothing"


=item I<-fallback> section

Specifies a section to be used for parameters outside a section. Default is none.
Without -fallback specified (which is the default), reading a configuration file
which has a parameter outside a section will fail. With this set to, say,
"GENERAL", this configuration:

   wrong=wronger

   [joe]
   name=Joseph

will be assumed as:

   [GENERAL]
   wrong=wronger

   [joe]
   name=Joseph

Note that Config::IniFiles will also omit the fallback section header when
outputing such configuration.

=item I<-nocase> 0|1

Set -nocase => 1 to handle the config file in a case-insensitive
manner (case in values is preserved, however).  By default, config
files are case-sensitive (i.e., a section named 'Test' is not the same
as a section named 'test').  Note that there is an added overhead for
turning off case sensitivity.


=item I<-import> object

This allows you to import or inherit existing setting from another
Config::IniFiles object. When importing settings from another object,
sections with the same name will be merged and parameters that are
defined in both the imported object and the I<-file> will take the
value of given in the I<-file>.

If a I<-default> section is also given on this call, and it does not
coincide with the default of the imported object, the new default
section will be used instead. If no I<-default> section is given,
then the default of the imported object will be used.


=item I<-allowcontinue> 0|1

Set -allowcontinue => 1 to enable continuation lines in the config file.
i.e. if a line ends with a backslash C<\>, then the following line is
appended to the parameter value, dropping the backslash and the newline
character(s).

Default behavior is to keep a trailing backslash C<\> as a parameter
value. Note that continuation cannot be mixed with the "here" value
syntax.


=item I<-allowempty> 0|1

If set to 1, then empty files are allowed at L</ReadConfig|ReadConfig()>
time. If set to 0 (the default), an empty configuration file is considered
an error.


=item I<-negativedeltas> 0|1

If set to 1 (the default if importing this object from another one),
parses and honors lines of the following form in the configuration
file:

  ; [somesection] is deleted

or

  [inthissection]
  ; thisparameter is deleted

If set to 0 (the default if not importing), these comments are treated
like ordinary ones.

The L</WriteConfig|WriteConfig($filename, -delta=>1)> form will output such
comments to indicate deleted sections or parameters. This way,
reloading a delta file using the same imported object produces the
same results in memory again. See L<IMPORT / DELTA FEATURES> for more
details.

=item I<-commentchar> 'char'

The default comment character is C<#>. You may change this by specifying
this option to another character. This can be any character except
alphanumeric characters, square brackets or the "equal" sign.


=item I<-allowedcommentchars> 'chars'

Allowed default comment characters are C<#> and C<;>. By specifying this
option you may change the range of characters that are used to denote a
comment line to include any set of characters

Note: that the character specified by B<-commentchar> (see above) is
I<always> part of the allowed comment characters.

Note 2: The given string is evaluated as a regular expression character
class, so '\' must be escaped if you wish to use it.


=item I<-reloadwarn> 0|1

Set -reloadwarn => 1 to enable a warning message (output to STDERR)
whenever the config file is reloaded.  The reload message is of the
form:

  PID <PID> reloading config file <file> at YYYY.MM.DD HH:MM:SS

Default behavior is to not warn (i.e. -reloadwarn => 0).

This is generally only useful when using Config::IniFiles in a server
or daemon application. The application is still responsible for determining
when the object is to be reloaded.


=item I<-nomultiline> 0|1

Set -nomultiline => 1 to output multi-valued parameter as:

 param=value1
 param=value2

instead of the default:

 param=<<EOT
 value1
 value2
 EOT

As the later might not be compatible with all applications.

=item I<-handle_trailing_comment> 0|1

Set -handle_trailing_comment => 1 to enable support of parameter trailing
comments.

For example, if we have a parameter line like this:

 param1=value1;comment1

by default, handle_trailing_comment will be set to B<0>, and we will get
I<value1;comment1> as the value of I<param1>. If we have
-handle_trailing_comment set to B<1>, then we will get I<value1>
as the value for I<param1>, and I<comment1> as the trailing comment of
I<param1>.

Set and get methods for trailing comments are provided as
L</SetParameterTrailingComment> and L</GetParameterTrailingComment>.

=head2 val ($section, $parameter [, $default] )

Returns the value of the specified parameter (C<$parameter>) in section
C<$section>, returns undef (or C<$default> if specified) if no section or
no parameter for the given section exists.


If you want a multi-line/value field returned as an array, just
specify an array as the receiver:

  @values = $cfg->val('Section', 'Parameter');

A multi-line/value field that is returned in a scalar context will be
joined using $/ (input record separator, default is \n) if defined,
otherwise the values will be joined using \n.

reading.

If an error occurs while parsing the INI file the @Config::IniFiles::errors
array will contain messages that might help you figure out where the

=head2 Groups

Returns an array containing the names of available groups.

Groups are specified in the config file as new sections of the form

  [GroupName MemberName]

This is useful for building up lists.  Note that parameters within a
"member" section are referenced normally (i.e., the section name is
still "Groupname Membername", including the space) - the concept of
Groups is to aid people building more complex configuration files.

=cut

sub GetWriteMode

=head2 WriteConfig ($filename [, %options])

Writes out a new copy of the configuration file.  A temporary file
is written out and then renamed to the specified filename.  Also see
B<BUGS> below.

If C<-delta> is set to a true value in %options, and this object was
imported from another (see L</new>), only the differences between this
object and the imported one will be recorded. Negative deltas will be
encoded into comments, so that a subsequent invocation of I<new()>
with the same imported object produces the same results (see the
I<-negativedeltas> option in L</new>).

C<%options> is not required.

Returns true on success, C<undef> on failure.

=head1 USAGE -- Tied Hash

=head2 tie %ini, 'Config::IniFiles', (-file=>$filename, [-option=>value ...] )

Using C<tie>, you can tie a hash to a B<Config::IniFiles> object. This creates a new
object which you can access through your hash, so you use this instead of the
B<new> method. This actually creates a hash of hashes to access the values in
the INI file. The options you provide through C<tie> are the same as given for
the B<new> method, above.

Here's an example:

  use Config::IniFiles;

  my %ini
  tie %ini, 'Config::IniFiles', ( -file => "/path/configfile.ini" );

  print "We have $ini{Section}{Parameter}." if $ini{Section}{Parameter};

Accessing and using the hash works just like accessing a regular hash and
many of the object methods are made available through the hash interface.

For those methods that do not coincide with the hash paradigm, you can use
the Perl C<tied> function to get at the underlying object tied to the hash
and call methods on that object. For example, to write the hash out to a new
ini file, you would do something like this:

  tied( %ini )->WriteConfig( "/newpath/newconfig.ini" ) ||
    die "Could not write settings to new file.";

=head2 $val = $ini{$section}{$parameter}

Returns the value of $parameter in $section.

Multiline values accessed through a hash will be returned
as a list in list context and a concatenated value in scalar
context.

=head2 $ini{$section}{$parameter} = $value;

Sets the value of C<$parameter> in C<$section> to C<$value>.

To set a multiline or multiv-alue parameter just assign an
array reference to the hash entry, like this:

 $ini{$section}{$parameter} = [$value1, $value2, ...];

If the parameter did not exist in the original file, it will
be created. However, Perl does not seem to extend autovivification
to tied hashes. That means that if you try to say

  $ini{new_section}{new_paramters} = $val;

and the section 'new_section' does not exist, then Perl won't
properly create it. In order to work around this you will need
to create a hash reference in that section and then assign the
parameter value. Something like this should do nicely:

  $ini{new_section} = {};
  $ini{new_section}{new_paramters} = $val;

=head2 %hash = %{$ini{$section}}

Using the tie interface, you can copy whole sections of the
ini file into another hash. Note that this makes a copy of
the entire section. The new hash in no longer tied to the
ini file, In particular, this means -default and -nocase
settings will not apply to C<%hash>.


=head2 $ini{$section} = {}; %{$ini{$section}} = %parameters;

Through the hash interface, you have the ability to replace
the entire section with a new set of parameters. This call
will fail, however, if the argument passed in NOT a hash
reference. You must use both lines, as shown above so that
Perl recognizes the section as a hash reference context
before COPYing over the values from your C<%parameters> hash.

=head2 delete $ini{$section}{$parameter}

When tied to a hash, you can use the Perl C<delete> function
to completely remove a parameter from a section.

=head2 delete $ini{$section}

The tied interface also allows you to delete an entire
section from the ini file using the Perl C<delete> function.

=head2 %ini = ();

If you really want to delete B<all> the items in the ini file, this
will do it. Of course, the changes won't be written to the actual
file unless you call B<RewriteConfig> on the object tied to the hash.

=head2 Parameter names

=over 4

=item my @keys = keys %{$ini{$section}}

=item while (($k, $v) = each %{$ini{$section}}) {...}

=item if( exists %{$ini{$section}}, $parameter ) {...}

=back

When tied to a hash, you use the Perl C<keys> and C<each>
functions to iteratively list the parameters (C<keys>) or
parameters and their values (C<each>) in a given section.

You can also use the Perl C<exists> function to see if a
parameter is defined in a given section.

Note that none of these will return parameter names that
are part of the default section (if set), although accessing
an unknown parameter in the specified section will return a
value from the default section if there is one.


=head2 Section names

=over 4

=item foreach( keys %ini ) {...}

=item while (($k, $v) = each %ini) {...}

=item if( exists %ini, $section ) {...}

=back

When tied to a hash, you use the Perl C<keys> and C<each>
functions to iteratively list the sections in the ini file.

You can also use the Perl C<exists> function to see if a
section is defined in the file.

# TIEHASH Methods

# user wants to look at thinks like $ini{sec}{parm}, but the
# TIEHASH only provides one level of hash interace, so the
# root object gets asked for a $ini{sec}, which this
# implements. To further tie the {parm} hash, the internal
# class Config::IniFiles::_section, is provided, below.

# INTERNAL PACKAGE: Config::IniFiles::_section
#
# Description:
# This package is used to provide a single-level TIEHASH
# interface to the sections in the IniFile. When tied, the
# user wants to look at thinks like $ini{sec}{parm}, but the
# TIEHASH only provides one level of hash interace, so the
# root object gets asked for a $ini{sec} and must return a
# has reference that accurately covers the '{parm}' part.
#
# This package is only used when tied and is inter-woven
# between the sections and their parameters when the TIEHASH
# method is called by Perl. It's a very simple implementation
# of a tied hash object that simply maps onto the object API.

=head1 IMPORT / DELTA FEATURES

The I<-import> option to L</new> allows one to stack one
I<Config::IniFiles> object on top of another (which might be itself
stacked in turn and so on recursively, but this is beyond the
point). The effect, as briefly explained in L</new>, is that the
fields appearing in the composite object will be a superposition of
those coming from the ``original'' one and the lines coming from the
file, the latter taking precedence. For example, let's say that
C<$master> and C<overlay> were created like this:

   my $master  = Config::IniFiles->new(-file => "master.ini");
   my $overlay = Config::IniFiles->new(-file => "overlay.ini",
            -import => $master);

If the contents of C<master.ini> and C<overlay.ini> are respectively

   ; master.ini
   [section1]
   arg0=unchanged from master.ini
   arg1=val1

   [section2]
   arg2=val2

and

   ; overlay.ini
   [section1]
   arg1=overriden

Then C<< $overlay->val("section1", "arg1") >> is "overriden", while
C<< $overlay->val("section1", "arg0") >> is "unchanged from
master.ini".

This feature may be used to ship a ``global defaults'' configuration
file for a Perl application, that can be overridden piecewise by a
much shorter, per-site configuration file. Assuming UNIX-style path
names, this would be done like this:

   my $defaultconfig = Config::IniFiles->new
       (-file => "/usr/share/myapp/myapp.ini.default");
   my $config = Config::IniFiles->new
       (-file => "/etc/myapp.ini", -import => $defaultconfig);
   # Now use $config and forget about $defaultconfig in the rest of
   # the program

Starting with version 2.39, I<Config::IniFiles> also provides features
to keep the importing / per-site configuration file small, by only
saving those options that were modified by the running program. That
is, if one calls

   $overlay->setval("section1", "arg1", "anotherval");
   $overlay->newval("section3", "arg3", "val3");
   $overlay->WriteConfig('overlay.ini', -delta=>1);

C<overlay.ini> would now contain

   ; overlay.ini
   [section1]
   arg1=anotherval

   [section3]
   arg3=val3

This is called a I<delta file> (see L</WriteConfig>). The untouched
[section2] and arg0 do not appear, and the config file is therefore
shorter; while of course, reloading the configuration into C<$master>
and C<$overlay>, either through C<< $overlay->ReadConfig() >> or through
the same code as above (e.g. when application restarts), would yield
exactly the same result had the overlay object been saved in whole to
the file system.

The only problem with this delta technique is one cannot delete the
default values in the overlay configuration file, only change
them. This is solved by a file format extension, enabled by the
I<-negativedeltas> option to L</new>: if, say, one would delete
parameters like this,

   $overlay->DeleteSection("section2");
   $overlay->delval("section1", "arg0");
   $overlay->WriteConfig('overlay.ini', -delta=>1);

The I<overlay.ini> file would now read:

   ; overlay.ini
   [section1]
   ; arg0 is deleted
   arg1=anotherval

   ; [section2] is deleted

   [section3]
   arg3=val3

Assuming C<$overlay> was later re-read with C<< -negativedeltas => 1 >>,
the parser would interpret the deletion comments to yield the correct
result, that is, [section2] and arg0 would cease to exist in the
C<$overlay> object.

=head1 DIAGNOSTICS

=head2 @Config::IniFiles::errors

Contains a list of errors encountered while parsing the configuration
file.  If the I<new> method returns B<undef>, check the value of this
to find out what's wrong.  This value is reset each time a config file
is read.

=head1 BUGS

=over 3

=item *

The output from [Re]WriteConfig/OutputConfig might not be as pretty as
it can be.  Comments are tied to whatever was immediately below them.
And case is not preserved for Section and Parameter names if the -nocase
option was used.

=item *

No locking is done by [Re]WriteConfig.  When writing servers, take
care that only the parent ever calls this, and consider making your
own backup.
