d2

A modern diagram scripting language that turns text to diagrams. Note: the output file supports SVG and PNG file formats. More information: https://d2lang.com/tour/man.

• Compile and render a D2 source file into an output file:

d2 {{path/to/input_file.d2}} {{path/to/output_file.ext}}

• Watch live changes made to a D2 source file in the default web browser:

d2 {{[-w|--watch]}} {{path/to/input_file.d2}} {{path/to/output_file.ext}}

• Format a D2 source file:

d2 fmt {{path/to/input_file.d2}}

• List available themes:

d2 themes

• Use a different theme for the output file (list available themes first to get the desired theme_id):

d2 {{[-t|--theme]}} {{theme_id}} {{path/to/input_file.d2}} {{path/to/output_file.ext}}

• Make rendered diagrams look like hand sketches:

d2 {{[-s|--sketch]}} true {{path/to/input_file.d2}} {{path/to/output_file.ext}}
