    goquery

    goquery

    A little like that j-thing, only in Go

    goquery brings a syntax and a set of features similar to jQuery to the Go language. It is based on Go's net/HTML package and the CSS Selector library Cascadia. Since the net/html parser returns nodes, and not a full-featured DOM tree, jQuery's stateful manipulation functions (like height(), css(), and detach()) have been left off. Also, because the net/HTML parser requires UTF-8 encoding, so does goquery: it is the caller's responsibility to ensure that the source document provides UTF-8 encoded HTML. ...

    Desktop client for Facebook Messenger

    Goofy is a macOS client for Facebook Messenger. But unlike most other clients, it does not use any of Facebook's APIs, but is basically a single-site browser that injects a little CSS and JS into messenger.com to make it a little more app-like. Feel free to create issues on this repo for feature requests of any kind. However, some features may not be possible due to the way this application is working. Also, I don't want this to be a feature-bloated monster, but a slick and small app. Depending on the number of contributors and the progress of this app, I will schedule releases from time to time, which will then be distributed on goofyapp.com. ...
