Erlang World Creator

This application is created to create objects following certain models. The models is put in header file that will be read into ewoc.

Then users can create objects for test by stating what kind of objects should be created. Still under developing.

Start

Download the repo from Git.

make start

This will start the application.

Examples

The system will need a model.hrl file as a comfiguration file, later it maybe will be a config file. But at start it is a .hrl file.

-define(MODELS, [{book, ?BOOK},
                 {car, ?CAR}]).

-define(BOOK, [{author, binary},
               {title, binary}]).

-define(CAR, [{engine, binary},
              {tires, binary},
              {doors, integer}]).

This will give ewoc information on how it should build the different models and get information on how to populate them. What types fields should have. To create model objects you can use this code:

        ewoc_model_handler:create([{book, 3, []},
                                   {car, 5, []}]).

This will create three book models that are empty and five car models that are empty. Later it will be available to put default models in your model.

But for now we must tell ewoc to populate data to the model.

        ewoc_model_handler:create([{book, 3,
                                  [{author, [{words, [{wsize, [6, 20]}]}]}]
                                  }]).

This will create three books with field author populated with words, and the size on the two words will be 6 and 20 chars.

Example

Start application with start.sh

ewoc_model_handler:create([{book, 3, [{author, [{words, [{wsize, [6, 20]}]}]}] }]).

This will create three books with field author populated with words, and the size on the two words will be 6 and 20 chars.

Example

make start

Eshell V5.9.1  (abort with ^G)
1> ewoc_model_handler:create([{book, 3, [{title, [{words, [{wsize, [6, 20]}]}]}]}]).
[{book,[[{author,[]},
         {amount,[]},
         {title,<<"HJFudP ENqnSWYmWFbxvHQWaFod">>}],
        [{author,[]},
         {amount,[]},
         {title,<<"RUbkjr uLpEPUTIuFDZccbaQnrR">>}],
        [{author,[]},
         {amount,[]},
         {title,<<"FqAXLx ZEdquyDavxlDiKkhFyIV">>}]]}]
