IDEs like Atom should have a drop-down export function. There is nothing more frustrating than working for hours on a document and spending more hours fighting with a function like Weave to make a pdf, html, or latex.
This is kinda to the side of the actual code, and it really is a disadvantage, for a language meant for number crunching.
The VS Code extension for Julia has a command Julia Weave: Save to file... and then you can pick a file type you want to export to and it will weave the content of the currently active jmd file into that format. I think that is what you are looking for, right?
Questions like this should go into the Tooling category.
