Show HN: Generate high-res images of code samples with Chrome Headless

My workflow:

One time setup

    $ python -m venv ve
    $ source ve/bin/activate
    $ pip install pygments WeasyPrint

Then

    $ pygmentize -f html src.py | weasyprint - out.pdf

Both pygmentize and weasyprint have many options to play with. I find a set and create a shell script.

This also does pngs, etc:

    $ pygmentize -f html src.py | weasyprint - out.png

Can’t you it directly using Pygments’ ImageFormatter?

Apparently so! I don't generate images myself, so i didn't know.

    $ pygmentize -o out.png src.py

Neat.

I use vim for writing out html:

  :TOhtml

I found it to create the prettiest syntax highlighted code. But I'm bias because it produces html using my vim color scheme which I'm partial too :)

You can script vim too by specifying a list of commands in a file then running it:

  $ vim -S myscript some_file
