It lets you create a CLI-based wizard just by providing a few arguments. The README is fantastic and packed with examples and animations. And if you’d rather brew your own in your own Go code, [Bubble Tea](https://github.com/charmbracelet/bubbletea) and [Lip Gloss](https://github.com/charmbracelet/lipgloss), upon which Gum depends, are waiting for you too.

Note, though, _“If you must read the rest of this document to understand the behavior of your program, you are being too clever.”_ The Go Team [GoLand 2022.2 Released](https://blog.jetbrains.com/go/2022/07/28/goland-2022-2-is-here/) — The latest version of JetBrains’ popular (commercial) Go IDE is here with new features supporting generics and Go workspaces as well as fuzz testing. _“In addition, GoLand now supports WebSocket connections and can send GraphQL queries over HTTP and WebSocket protocols.”_ JetBrains **QUICK BITS:** - Developers at Google are working on [Carbon](https://github.com/carbon-language/carbon-lang#carbon-language--an-experimental-successor-to-c), an 'experimental successor to C++'.
