rollup-plugin-spl

A Rollup plugin to create Software Product Lines with the help of MetaScript.

Installation

Install rollup-plugin-spl dependency

npm install --save-dev rollup-plugin-spl

Add rollup-plugin-spl to your rollup.config.js

import rollupPluginSpl from "rollup-plugin-spl";

export default {
    ...
    plugins: [
        rollupPluginSpl({
            // set options here
        }),
        ...
    ],
}

Options

• model: either the path to your model or the preloaded model
• config: either the path to your configuration or the preloaded configuration
• verify: if truthy, the configuration is verified with the model. Only features required for the configuration to be a valid partial configuration are selected.
• autocomplete: if truthy, unselected features will be selected to form a complete configuration. To configure whether the features are selected positive or negative, an object {preference: <true|false>} can be passed.
• interactive: asks the user which unselected features should be selected positive and which negative. Compatible with config for a predefined partial selection and autocomplete to fill in features not selected by the user.

Create the SPL model

To create the model, run node node_modules/splconfigurator/target/splconfigurator.cjs.js build <Modelname>. A detailed explanation of the process can be found in the manual for the SPL Configurator.

Create an SPL configuration

To create a configuration for your SPL, run node node_modules/splconfigurator/target/splconfigurator.cjs.js configure path/to/your/model. A detailed explanation of the process can be found in the manual for the SPL Configurator.

Write the code

To exclude parts of your source code when a certain feature is selected positive or negative, wrap it inside a MetaScript if else:

console.log("always included");
//? if (INCLUDE_A) {
console.log("feature INCLUDE_A is selected");
//? } else {
console.log("feature INCLUDE_A is not selected");
//? }

This process is similar to ifdef from the cpp. A detailed explanation can be found in the MetaScript manual
