enabling uos features in unix port

[bitrat]

Hi all,

I wonder if the Makefile and mpconfigport.h macro definitions for enabling features in the uos module are documented anywhere?

Cheers!

Not that I'm aware of.

uos is a bit complicated because it varies between ports.

What would you like to enable?

I was looking for getcwd().
I can work the rest out from an example.

I've tried defining a few config macros here and there without much success but I haven't really got time to figure it all out.

I'm building on WSL (Linux HPZ17G5-3G18 4.4.0-18362-Microsoft #476-Microsoft Fri Nov 01 16:53:00 PST 2019 x86_64 x86_64 x86_64 GNU/Linux)

Did you see the os module in micropython-lib, which provides a lot of os funtions, including getcwd(). It is available via 'import os'

You have to install micropython.lib or the required packages on your system. See the README in https://github.com/micropython/micropython-lib

cool! thanks, I didn't know that
very handy!
