Here's a question I never thought about too much - does Pex work on Windows?
b
Not yet, but John has been looking into it. There's been updates
w
👍 What about in WSL2? I would assume it "should" work there?
b
I suspect so, but don't quote me
c
I think there are subtle issues with it, but don’t quote me either 😛
h
It works in WSL2 (so does Pants!)
@enough-analyst-54434 has been working on getting pex to work on Windows
e
Yeah, Pex works on Windows in a branch save for ~50 unit tests. All the ITs now pass. Python 3.8+
And I hack on Pex currently mainly in Windows and WSL2, flipping back and forth.
The thing about WSL is its a pretty horrible experience unless you stay isolated to WSL. The file sharing back to WIndows is over plan9 fs and its super laggy.

Oooh, dope!

I recall this in another slack thread with the pants daemon being off as somehow the workaround.

This is just Pex hacking, no Pants in sight. Things are super slow if you work across 
/mnt/c
/ 
\\wsl\
boundaries.
w
Yep, thats' cool - I just found out that some of the devs I'm working with are using Windows machines sometimes, so trying to see if I can bundle a pex for them (someday)

What’s the latest on having Windows support? I think this may be the problem I’m facing 🙂

We're working on pex support for Windows, it's a work-in-progress, but there has been a lot of progress

Great!
e
PEX support for Windows doesn't mean Pants support for Windows. IIUC no one is looking at Pants own Windows issues yet seriously; so Pants support should be considered far out. You'll need to use WSL and only use clones in WSL, no /mnt/c !
s
Aha.. @enough-analyst-54434 thanks for the clarification 🙂
