Issue 808719: IDLE and encodings (original) (raw)

A person from Belgium reported this problem in IDLE to python-help:

$ python idle Traceback (most recent call last): File "idle", line 10, in ? import PyShell File "PyShell.py", line 25, in ? from EditorWindow import EditorWindow, fixwordbreaks File "EditorWindow.py", line 39, in ? class EditorWindow: File "EditorWindow.py", line 43, in EditorWindow from IOBinding import IOBinding File "IOBinding.py", line 54, in ? codecs.lookup(encoding) File "/ap/tools/storage/python/v2.2.2.224_ap/lib/python2.2/ encodings/init.py",

line 51, in search_function mod = import(modname,globals(),locals(),'*') ValueError: Empty module name

It seems that checking for an encoding of "" as well as None in IOBinding.py fixes the problem. I'll attach his small patch.

IDLE 1.0

One last remark, last time I remenber that the problem of codec lookup also appeared in other circumstances than starting IDLE.
