I'd recommend settling on some JS library and using it via appropriate interop.

prosemirror may be worth looking into, its a fork of codemirror designed for working with markdown

You can't.

Is that CLJS code running on Node or in a browser?

I need to call some python files from my cljs

But where do you run that CLJS code, on which platform - browser or Node? Or something else?

browser

The only choice is to create an endpoint on your server that, when requested, uses clojure.java.shell. And then hit that endpoint from the CLJS code.

Although, there's another alternative if you're willing to run an additional server and deal with CORS. You can create that special endpoint within a separate Python server and run the Python code from there, without the need for clojure.java.shell. But the overall concept is still the same.

Agreed, Both are good suggestions. Let me try the later. Thanks :)

@U2FRKM4TW pyodide is an option

if you simply need to run Python in the browser

That's a big if, but perhaps a viable option for the OP.

My point was to distinguish between merely executing Python logic and executing Python logic that manipulates a host (i.e., sandboxed or not). From CLJS, is beside the point
