There is already a new version of the Occam IDE available, which you can download from the Occam website. It includes improvements around the grammars as well as a new Unicode picker.
There's some fun to be had in working with the grammars, even if you've never done this kind of thing before. If you take a moment to clone the repository and have a look at the examples, you'll see that you are able to work with them directly.
I am especially interested in (and would be especially grateful for) contributions to the JavaScript grammar.Any contributions would be hugely appreciated, however.
The seeming lack of any discernible styling on my homepage is intentional (in fact there is a little, but still). I don't want to detract from the content.
The paragraph font size is sixteen pixels, by the way, which is pretty standard and happens to be four pixels more than this site, which I assume you can read just fine.
