NAME
Config::Model::CursesUI - Curses interface to edit config data SYNOPSIS
use Config::Model ; use Config::Model::CursesUI ; my $model = Config::Model -> new ; my $inst = $model->instance (root_class_name => 'XXX', instance_name => 'yyy'); # create dialog my $dialog = Config::Model::CursesUI-> new ( experience => 'beginner', # or 'advanced' ) ; # start never returns $dialog->start($model) ; DESCRIPTION
This class provides a Curses::UI interface to configuration data managed by Config::Model. IMPORTANT: Once the CursesUI object is created, STDOUT and STDERR are managed by the Curses interface, so all print and warn will not work as expected. CONSTRUCTOR
The constructor accepts the following parameters: experience Specifies the experience level of the user (default: "beginner"). The experience can be "master advanced beginner". load Subroutine ref containing the code to load the configuration data from the configuration files. This may overrides loading mechanism specified in the model with Config::Model::AutoRead. This sub is called without any arguments. store Subroutine ref containing the code to store the configuration data in the configuration files. This may overrides writing mechanism specified in the model with Config::Model::AutoRead. This sub is called without any arguments. AUTHOR
