Please note that this is a prototype under development. It is not thought to use in a production environment yet.

• Pure::variants v5.0: Our SPL is build on top of pure::variants. Pure::variants is an eclipse plugin for development and deployment of products lines and software families.
  • Evaluation Software to develop it.
• NodeJS v12: required to compile the resultant generated products. We recommend you to use nvm for UNIX-like systems or for windows to manage multiple versions of nodeJS installed in your system.
• Gulp v4: a javascript toolkit to manage build tasks over nodeJS. To install it globally run: npm install -g gulp

Step 1. You can create a product variant in ./Variants/ folder in Eclipse. Configure with the features that your feedback app must have to conduct your annotation activity.

Step 2. Generate the product, the resultant will be placed in ./output/<name_of_your_product>

Step 3. Resolve dependencies and compile:

• In windows systems: Open a powershell and execute in ./output/<name_of_your_product> folder: ./dependencies.ps1
• In UNIX-like systems: Open a shell and execute in ./output/<name_of_your_product> folder: ./dependencies.sh

Step 4. A compiled browser extension is created in ./output/<name_of_your_product>/dist folder. Drag and drop to your browser's extensions folder (remember that Developer mode must be activated)

Step 5. Test the installed extension in the browser

We have created two variants that can be used as an example:

• ReviewAndGo
• MetaReviewAndGo

Each of the derived products from WacLine are ready to build, test and pack to delivery in browser extensions stores (e.g: Chrome Web Store). Here are described some gulp tasks to facilitate these activities:

Note that ./dependencies.sh or ./dependencies.ps1 described above builts the browser extension to install as a developer in chrome. The following section describes other available options for building.

$ gulp

Zips your dist directory and saves it in the packages directory.

$ gulp pack --vendor=firefox

We are currently planning to automatize web annotation clients testing using puppeteer.
