Rich has become a popular (20K stars on GH) way of beautifying CLIs, and I'm pleased to see a number of projects using it.
Since Rich is mature and battle-tested now, I had considered winding-down development. Until, I saw this tweet:

Do you want to see something really cool you can do with @willmcgugan 's rich library?
Checkout ghtop https://t.co/mn7oLbpw8e. It's a really fun CLI tool that demonstrates the power of rich (and other things).

@HamelHusain and @jeremyphoward used Rich to enhance ghtop (a repo owned by the CEO of Github, no less). Ghtop shows a realtime a stream of events from the Github platform. And it looks good! So good that I realised how much potential Rich has for these type of htop-like applications.
Hamel and Jeremy had to overcome a few technical hurdles to make that work. Fortunately this will no longer be required as the latest version of Rich has first-class support for full-screen interfaces via a new Layout system.
Full-screen terminal interface
Here's a video demonstration of a terminal interface built with Layout:
Layout API
The API to create a flexible layout is surprisingly simple. You construct a
Layout()
object, then call split()
to create sub-layouts. These sub-layouts may then be further divided. Layouts have a small number of settings which define their size relative to the terminal window. It's a simple system that can create terminal interfaces that almost resemble modern web apps.Finally, some code

Here's how you would create a basic layout with a header, a footer, and two side-panels. Bias fx dmg torrent full.
Running the code above produces the following output:
Any renderable (text, table, progress bars etc) may be placed inside those sub-layouts.
We can now use the Live class to create an application that adapts itself to the terminal window:
In a real app, that do-nothing loop will be doing something useful like pulling data from the network to update contents.

What's next?
I think it's clear that Rich is acquiring more TUI (text user interface) features, and I've decided not to fight it. Rich's core purpose is still to beautify CLI output, but I think there is an opportunity here for a new way to create terminal apps. Ultimately it will be less like curses and more like HTML in a browser.
There are a number of things to do before Rich could replace a full TUI library (keyboard and mouse input for one) but the potential is there. Stay tuned for progress.
