[windows]no os.listdir and help

Post by oyster » Thu Feb 18, 2021 3:12 pm

I have compiled `micropython.exe` in msys2+mingw64. there is `os.ilistdir`, but no `os.listdir` which exists on esp8266

there is no `help` too

what is the step to enable/disable these specified functions on windows? Thanks

Code: Select all

>>> import os
>>> dir(os)
['__class__', '__name__', 'remove', 'errno', 'getenv', 'ilistdir', 'mkdir', 'putenv', 'rename', 'rmdir', 'stat', 'system', 'unsetenv']
>>> help('modules')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'help' isn't defined

I'm not entirely sure why the Unix port (and the Windows which is based on the Unix port) don't implement listdir. It would be relatively straightforward to add. See ports/unix/modos.c

This can be enabled in ports/windows/mpconfigport.h -- add:

#define MICROPY_PY_BUILTINS_HELP (1)
#define MICROPY_PY_BUILTINS_HELP_MODULES (1)
