Problem loading module containing \r\n

[udmicpy]

Dear all.

Last week I made my first steps with MicroPython and my ESP8266 12E.
I used ESPlorer on Windows 10 to upload code to the ESP8266.
All worked fine but when I tried to load the code of a simple webserver program as a module I got an error.

This is part of the code

......
def handleRequests(s):
cl, addr = s.accept()
print('client connected from', addr)
cl_file = cl.makefile('rwb', 0)
while True:
line = cl_file.readline()
if not line or line == b'\r\n': ### <<<--- THIS IS LINE 69 !!!
break
response = createHTML(getTemp())
cl.send(response)
cl.close()
......

The error was:
Traceback (most recent call last):
File "<stdin>", line 7, in <module>
File "myModule.py", line 69
SyntaxError: invalid syntax

I had to mask the "\" bei "\\" to make the import of this code as a module work.

Is this a bug or did I make a mistake?

Thanks a lot in advance.

Best regards, Uwe

There is no problem with \r or \n in MicroPython string handling. I guess that ESPlorer is the culprit, doing an additional escaping of \. Try another tool like rshell or ampy or Webrepl for uploading.

Dear Robert,

thanks for your fast reply.
And indeed - it was a problem which I had only with ESPlorer.
Actually I'm using uPyLoader from this github project https://github.com/BetaRavener/uPyLoader
And with this tool I have no problems any more.

Bye, Uwe
