The general idea is to use an openscad grammar to parse the openscad code into a syntax tree, then use the tree to jenerate jscad code. In order to make the resulting code more readable or when jscad is missing an equivalent operation the code adds helper functions.

I used the openscad version of the honeycomb storage wall (on printables) as my test case and it successfully converts it to jscad. Each language feature is added separately so there are still many more to add.

If anyone wants to try it out or contribute let me know. I haven't had time to work on it recently but would love to make more progress. Index.js is the starting point.

As a side note - you can run jscad code with auto-completion and typechecking in our site, cadit.app - let me know what you think!
