Hey @VishnuSanal 👋

I am unable to understand the changes. Could you add an example on why we need the new parameters?

And how you'd invoke the changes?

Hey @VishnuSanal , Could you please update the PR description with the above??

[VishnuSanal]

uh, oh. my previous comment never got sent.

Could you add an example on why we need the new parameters?

I have changed the implementation, PTAL. removed the need for new params.

And how you'd invoke the changes?

running as a module usually, like python3 -m app --dev would do.

please CMIIW.

@VishnuSanal , I just saw your description. That is not what we want to solve for 😄

We want to allow the dev mode to work like robyn -m src --dev. The robyn_app in description is src here

where src

src/
  - __init__.py
  - __main__.py

The --dev flag should rerender based on app changes.

thank you for the review, Sanskar! this currently works as expected in my testing, PTAL & LMK what you think. :)

Hey @VishnuSanal 👋

Thanks for the PR, I have some comments 😄

Hey @VishnuSanal 👋

Thanks for the update. I have some follow up comments

[VishnuSanal]

current issues:

• [ ] doesn't work when using robyn -m src --dev. sys.argv[0] returns the path to the executable. but, from here, it seems like we shouldn't run it like it, but like python3 -m src --dev.
• [ ] doesn't work during python3 app.py --dev (since path is not present in unknown_args in arguement_parser)
• [x] doesn't work during robyn app.py --dev

(will edit & update this comment as I fix them...)

[VishnuSanal]

note to self:

the flow of control is like: cli#run => cli#start_dev_server => reloader#setup_reloader => EventHandler#reload => Robyn#start and, we are getting the file object at the last stage. my current implementation starts a new dev server from there.

we need a way to bypass it the first time (inorder to reach robyn#start) and, then kill the previous reloader & start new one from there.

as of now, I am getting an infinite loop! will address. :)
