What happened?

I'm trying to setup oh-my-posh for cmd with clink. This is the oh-my-posh.lua:

load(io.popen('oh-my-posh init cmd'):read("*a"))()

When I open CMD I get:

@BeatsuDev this is highly likely a configuration issue on your device as I can't reproduce this with the exact same setup (except Windows 10.0.22000.0).

[BeatsuDev]

Hmmm okay, that's unfortunate... Do you have any ideas on how I can find out which configuration is messing up the initialization?

I tried finding out why load(io.popen('oh-my-posh init cmd'):read("*a")) was returning nil, but I couldn't find any alternatives or solutions to solve the issue :/

[JanDeDobbeleer]

@BeatsuDev it could be that somehow the PATH isn't loaded yet which causes the command itself to fail.

[BeatsuDev]

Ah thank you! I found out that it's because I have a script that echoes to the terminal every time a new instance is created. So it was attempting to parse the string Loaded aliases... as lua code.

I found out by simply printing out the return value of load (it shows the error too - i didn't know Lua returned errors like that): print(load(io.popen('oh-my-posh init cmd'):read('*a'))) showed:

nil     [string "Loaded aliases...."]:1: syntax error near 'aliases'
