Elevator Pitch
Support detecting and connecting the appropriate language server when a %%file <filename> magic is encountered.
Motivation
This would enable to a demo I've wanted to do for a while, namely, from within a single notebook session, with language server support:
- write an
environment.yml - write a
package.json - write a
tsconfig.json - write a
index.ts - write a
style.css - do the setup stuff in a new
app_dir(e.g. runpostBuild) - start up another
jupyter labserver in the same event loop - start up the
tsc --watchprocess - start up the
jupyter lab --watchprocess (probably not in-loop) - open an iframe in lab, of the other lab
- write a robot test
- iterate on any of the above, with live reloading
Design Ideas
I haven't dug much into the extractors, but this one would need a fair amount of custom behavior, since we wouldn't know a lot ahead of time. The only argument it takes is -a for append, which wouldn't be super useful, and it could be writing out to any path, which complicates matters.
The run-a-notebook-server-inside-a-kernel trick would work great.
Right now, the highlighting is fairly underpowered with %%file... while most of them would be around, maybe we bring in some ideas from simple-syntax, and even let language server specs ship a simple mode. Why not!
