reload python script

[OutoftheBOTS_]

I am currently using micropython running on an ESP32 for teaching high school kids robotics.

Once their robot becomes mobile we need to use webREPL to program the robot. We can upload the script with webREPL then type import script_name and it will run their script. Once the script is run then we need to do a CRTL-D in the REPL to softreset to be re run the script.

I used to have this in my boot.py to reload a script for this purpose. But for reason it now gives an error instead of reloading the script.

Code: Select all

import gc
from sys import modules
def reload(mod):
  mod_name = mod.__name__
  del sys.modules[mod_name]
  gc.collect()
  return __import__(mod_name)

What error?

There is an error in the script. It should read

Code: Select all

import gc
import sys  # Fix
def reload(mod):
  mod_name = mod.__name__
  del sys.modules[mod_name]
  gc.collect()
  return __import__(mod_name)

With the fix it works here (in main.py, which is preferred).

Code: Select all
