Capturing ANSI Output

Output to File

The most straight forward way is writing to a file then read that in Typst.

command > out.txt

Other Method

If writing to a file doesn't work, that means the program will detect the output and trim ANSI sequence accordingly, which means we need a pty interface to execute the script, the following should work in Linux:

script "command" out.txt
exit

About Default Font

Typst's default font for raw is Dejavu Sans Mono, but it has incorrect top-edge, so the default is set to Cascadia Code, which is included in web editor.
