Config::Model::Backend::IniFile - Read and write config as a INI file
version 1.242
use Config::Model; use Log::Log4perl qw(:easy); Log::Log4perl->easy_init($WARN); my $model = Config::Model->new; $model->create_config_class ( name => "IniClass", element => [ [qw/foo bar/] => { type => 'list', cargo => {qw/type leaf value_type string/} } ] ); # model for free INI class name and constrained class parameters $model->create_config_class( name => "MyClass", element => [ 'ini_class' => { type => 'hash', index_type => 'string', cargo => { type => 'node', config_class_name => 'IniClass' }, }, ], read_config => [ { backend => 'IniFile', config_dir => '/tmp', file => 'foo.conf', store_class_in_hash => 'ini_class', auto_create => 1, } ], ); my $inst = $model->instance(root_class_name => 'MyClass' ); my $root = $inst->config_root ; $root->load('ini_class:ONE foo=FOO1 bar=BAR1 - ini_class:TWO foo=FOO2' ); $inst->write_back ;
Now /tmp/foo.conf will contain:
/tmp/foo.conf
## file written by Config::Model [ONE] foo=FOO1 bar=BAR1 [TWO] foo=FOO2
This module is used directly by Config::Model to read or write the content of a configuration tree written with INI syntax in Config::Model configuration tree.
Config::Model
This INI file can have arbitrary comment delimiter. See the example in the SYNOPSIS that sets a semi-column as comment delimiter. By default the comment delimiter is '#' like in Shell or Perl.
Note that undefined values are skipped for list element. I.e. if a list element contains ('a',undef,'b'), the data structure will contain 'a','b'.
('a',undef,'b')
'a','b'
This backend tries to read and write comments from configuration file. The comments are stored as annotation within the configuration tree. Bear in mind that comments extraction is based on best estimation as to which parameter the comment may apply. Wrong estimations are possible.
Inherited from Config::Model::Backend::Any. The constructor will be called by Config::Model::AutoRead.
The constructor will be passed the optional parameters declared in the model:
Change the character that starts comments in the INI file. Default is '#'.
#
Of all parameters passed to this read call-back, only io_handle is used. This parameter must be IO::File object already opened for read.
io_handle
It can also be undef. In this case, read() will return 0.
read()
When a file is read, read() will return 1.
Of all parameters passed to this write call-back, only io_handle is used. This parameter must be IO::File object already opened for write.
write() will return 1.
write()
