jemdoc (or jemdoc+MathJax) has always been a good choice for light static website generating.
Yet, now it has a new design. If you know how to use jemdoc, there is no learning curve. The usage is exactly the same.
Demo: https://szl2.github.io/jemdoc-new-design/www/index.html
You need to download ./jemdoc,./www/main.css, ./www/table.css and ./jemdoc_files/mysite.conf files.
Notice that, you have to download the ./jemdoc excutable, because there were some modification from the original one in jemdox+Mathjax.
The usage is exactly the same as jemdoc. Refer this page for how to jemdoc.
Assuming you have already install the jemdoc+MathJax, notice that
in ./jemdoc_files/, we store .jemdoc files and mysite.conf
in ./www/, we store the output .html / .css / .js files and website assets.
Suppose you are currently in ./jemdoc_files/, we use the following to compile
python ../jemdoc -c mysite.conf -o ../www/ *.jemdoc
You can also use this for single page generation or all page generation by using *.jemdoc.
