Addon Scaffold

This is a part of Node3D project.

Synopsis

Generates either a dependency-module or a compiled-module from JSON description. The resulting modules can be further specified and developed by hand and then published to NPM. Install globally, because there is no point installing it locally.

Install

npm i -g addon-scaffold-raub

Usage

addon-scaffold description.json - scaffolds into the current directory.

addon-scaffold description - file extension is optional.

In JSON there are several parameters, that define an outcome:

• type - "addon" or "deps", is required.

• name - module name, is required.

• gitid - git user name, is required.

• desc - short module summary, defaults to "TODO(module description)".

• author - name of the author, defaults to "John Doe".

• email - email of the author, defaults to "[email protected]".

Additionally, "addon" description can have a parameter, named "classes". If so, it should be a nested object, containing a whole list of classes to be generated for the addon.

	"classes" : {
		"Class1" : {
			"inherits" : "EventEmitter",
			"properties" : {
				"k1": "bool",
				"-k2": "fun",
				"-k3": "uint32"
			}
		},
		"Class2" : {
			"methods" : {
				"f1" : { "p1": "int32", "p2": "utf8", "p3": "float", "p4": "obj" }
			}
		},
		"Class3" : {
			"inherits" : "Class1",
		}
	}

Here the keys of "classes" object are the names of the classes to be generated. Each class has a set of optional arguments:

• "inherits" - a string containing parent class name:
  • could be one of classes defined in this JSON
  • could be EventEmitter (C++ impl, imported from addon-tools-raub)
• "methods" - a nested object with per-method definitions:
  • key - method name,
  • value - a nested object with per-parameter definitions:
    • key - parameter name,
    • value - parameter type.
• "properties" - a nested object with per-property definitions:
  • key - property name, it can be prepended with - to make it read-only
  • value - property type.

Available types are:

• bool - boolean.
• utf8 - unicode string.
• int32 - integer.
• uint32 - unsigned integer.
• offs - pointer-size integer (int64 for x64).
• double - double precision float.
• float - single precision float.
• ext - external pointer.
• fun - function.
• obj - object.

Additional Notes

The addon-tools-raub package is used inside the templates.
