mhlogic_circuit's Introduction

MHlogic_circuit

My goal was to learn how to produce multiple images for inclusion in a single WW problem. It is possible, of course, to write pg code which will call TikZ from WW and produce excellent images for a problem on-the-fly, post-randomization. Using TikZ from withing WW is under active development. The approach here pre-produces the images, putting less load on the server when the questions are active. Of course, this requires more storage on the server, but disk capacity isn't an issue for us now.

Tool chain

LaTeX including TikZ produces pdf
ImageMagik: pdf -> pngs
dvisvgm: pdf -> svgs
The LaTeX files are based on a Jinja template
The pg file is created from a Jinja template
Configuration of each problem rests in a json file.
Python files control the Jinja templates
a make file controls the whole shebang

Requirements

python
- pathlib requires >= 3.6
jinja2
make (I use choco to install make under windows)
imagemagick
- which relies on Ghostscript
a modern LaTeX
- including TikZ and CircuiTikZ
- including latexmk
- including dvisvgm
