freeze cli to generate images of your terminal output
Introduction
charm
If you have not heard about charm you should definitely check out what they have.
The libraries and apps they have created the best good looking ones I have seen in a long time, they somehow have reinvented the way cli tools look like on the terminal, and for better.
freeze
freeze is one of the new cli tools they have created to generate images of code and terminal output
Similar to asciinema but focus on images, you can generate an image from the terminal and customize it as you wish. It is really mind blowing how good the images look.
