Rater

This is the source code for version 2 of the Wikipedia userscript Rater.

Installation instructions and user guide

See https://en.wikipedia.org/wiki/User:Evad37/rater.

Repository structure

• index.js is the main entry point, written in ES5. This is published to User:Evad37/rater.js (when deploying), or User:Evad37/rater/sandbox.js (for sandbox testing of changes). Or User:Evad37/rater/beta.js for beta testing.
• rater-src\ contains the main source code for the app, split into modules, which may be written in ES6. Code here can assume that the ResourceLoader modules specified in the above files have been loaded and that the DOM is ready.
  • App.js is the entry point
  • Related code should be placed in the same module.
  • Small pieces of code, not particularly related to anything, can be placed in rater-src\util.js
• The source code is bundled, transpiled, and minified using npm run build. This writes two files to the dist\ directory:
  • dist\rater.js contains bundled and transpiled code, with a source map. It is published to User:Evad37/rater/sandbox/app.js, for testing/debugging purposes.
  • dist\rater.min.js is the minified version. It is published to User:Evad37/rater/app.js (the live version of the userscript), once the sandbox version has been adequately tested. Or User:Evad37/rater/beta/app.js for beta testing.
• External scripts (other than those provided by MediaWiki) are located in the lib\ folder, and deployed to subpages of User:Evad37/rater/lib/.
  • This allows the bundled source code size to be smaller, and easier to work with. The scripts can be loaded with mw.loader.getScript, which returns a promise that resolves when the script is loaded.
  • These files must have licencing which, to be compatible with English Wikipedia (CC-BY-SA-3.0/GFDL), is permissive with regards to distribution, modification, and sublicencing. E.g. Apache, BSD, MIT licences are okay; GNU licences are not okay. See comparison table.

Tooling

• eslint for ES6 linting
• jshint for ES5 linting (ESLint doesn't support override for ecmaVersion)
• browserify with babelify for bundling, transpiling, and source-mapping
• uglifyjs for minifying

TODO

• Possible future features:
  • Have a preference for portlet location
  • Have a preference to autostart for particular talkpage categories
  • Have a preference to autostart for subject-page categories that match a word/regex pattern
  • Allow order of banners to be adjusted
• Investigate unit testing
  • Is node-based unit testing even possible, given the reliance on globals like mw and OO?
  • Look at how v1 is using QUnit unit testing. Maybe replicate or iterate on that.
  • Or maybe have QUnit tesing inside the app source code, that gets run if the url contains a query parameter such as &testrater=1?
• Improve documentation
• ... probably other things too - finish off this list, and/or put issues on the github page.

Roadmap

• Complete the v2 rewrite
• Get beta testers to try out the new version. Fix/adjust things as they get reported.
• Release the new version generally.
