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.

Install

MacOS

Using homebrew

brew install charmbracelet/tap/freeze

Linux

Any Linux platform using go

go install github.com/charmbracelet/freeze@latest

Use

Generate Image from STDOUT

freeze --execute "ls -la"

Generate image from a code file

freeze config.fish

If you prefer you can set the language

cat bash_script.sh | freeze --language bash

Customize

There are many options to customise the ouput on freeze

• margin, padding, window, width and height
• border: radius, width and color
• shadow: blur, x and y
• font: family, file, size and ligatures
• line-height, lines and show line numbers.

Interactive mode

The easiest way to customise freeze is by running the interactive mode

freeze --interactive bash_script.sh

# Changed

# Theme doom-one

Using flags

You can customise the output using flags too

freeze --theme doom-one bash_script.sh

Extras

Show line numbers

freeze --show-line-numbers bash_script.sh

Show only lines from X to Y

freeze --lines 2,5 --show-line-numbers bash_script.sh

Change the default freeze.png output file name and image type
