How To Install libconfig-model-itself-perl on Ubuntu 18.04
Introduction
In this tutorial we learn how to install libconfig-model-itself-perl on Ubuntu 18.04.
What is libconfig-model-itself-perl
libconfig-model-itself-perl is:
Config::Model::Itself module is a plugin for cme which provides a Perl/Tk graphical interface to edit configuration models that are be used by Config::Model.
Config::Model::Itself also provides a model for Config::Model (hence the Itself name, you can also think of it as a meta-model). The model editor will use this meta-model to construct the graphical interface so you can edit the configuration model for your application. [ Config::Model::Itself is the “eat your own dog food” principle applied to Config::Model ;-) ]
Let’s step back a little to explain. Any configuration data is, in essence, structured data. This data could be stored, for instance, in an XML file. A configuration model is a way to describe the structure and relation of all items of a configuration data set.
This configuration model is also expressed as structured data. This structure data is structured and follows a set of rules which are described for humans in Config::Model.
The structure and rules documented in Config::Model are also expressed in a model in the files provided with Config::Model::Itself.
Hence the possibity to verify, modify configuration data provided by Config::Model can also be applied on configuration models.
The model editor program launched with “cme meta edit”
