Libconf::Templates::Generic::Value - Libconf generic low level template for semantic (VALUE) styles config files
Libconf::Templates::Generic::Value is a generic template that handles config files that contain semantic informations of type : (VALUE).
$template = new Libconf::Templates::Generic::Value({
filename => 'some_filename',
regexp => '^\s*(\S+)\s*$',
comments_struct => [['#']],
output_function => sub { my ($atom) = @_; 'val : ' . $atom->{value} }
});
$template->read_conf();
$template->edit_atom(-1, { value => 'foo' }, { value => 'foo' });
$template->edit_atom(5, { value => 'some value' });
