9221 :: Help with converting Nim to JS at runtime

• Niminem (orginal) [2022-06-10T21:12:20+02:00] view original

  Hey guys,

  I'd like to convert Nim to JS during runtime and output as a string rather than a file. The end goal is to have a chrome extension that creates a "nim console" window within chrome dev tools.

  Any general guidance one can give here?

  I have a basic prototype working where the Nim code typed into a new console window is sent to a local server via websocket, a js file is produced, read, and then that js code is injected in the frontend.

  I don't think it's possible to compile the Nim compiler to js, however maybe it is possible to use the NimScript vm within the browser: https://peterme.net/how-to-embed-nimscript-into-a-nim-program-embedding-nimscript-pt-2.html

  Right, but how would I be able to get javascript produced out of the Nim code this way? I've used PMunch's articles to create a (sort of) Jupyter-Notebook like IDE but not in this manner. I only want to produce the javascript needed so I can inject it into the page.

  For things like finding links within a web page, highlighting certain text, etc.

  I think the only possible way is to compile the Nim compiler to WASM and then compile your Nim code to JS that way in the browser.

  Trim the compiler's source code to its essentials and make it compilable for the JS target. But it's not easy.
