Tasker reddit wallpaper

This repository contains the source code for a reddit wallpaper Tasker project.

Features:

• Wallpapers from latest best images in a subreddit.
• Updates wallpaper every x minutes
• Minimum resolution wallpapers.
• Offline and online modus.
• Never see a wallpaper twice (when online).
• Cached wallpapers (when offline).
• Notification with wallpaper title, buttons to skip wallpaper and to open post in browser.

The main project logic is written in Javascript inspired by TaskerJavaScriptHelpers. Similarly this repo contains a runner that runs Javascript as if it executed within Tasker and a builder that can be used to convert code for useage in a Tasker JavaScript action. Hats of for @StephenGregory for doing such a great writeup! This repo works very similarely with a few optimations:

• Es6 support by using webpack instead of browserify.
• Automatic re-running using nodemon.
• More Tasker Javascript functions are implemented.
• Tasker functions that are not implemented but are available throw an Error.
• Linting using Eslint.
• Testing using Jest.

Tasker project structure

This tasker project tries to implement all of its logic using Javascript, however as Tasker does not expose every action (nor profiles) a bit of Tasker "wizardry" is used.

2 profiles:

• Refresh wallpaper runs the script every x minutes.
• Notification Click handles clicking on te notification.

3 Tasks:

• Update Wallpaper main tasks, only runs Javascript.
• Wallpaper Notification implements the notify action for usage in Javascript.
• Open browser handles opening links from the notification.

Use in Tasker

Latest version of the wallpaper script can be found in dist/index.min.js and the Tasker project can be either imported using this DataUri or as xml:
