pure fails in Zsh on Linux subsystem (beta), Windows 10

[fredrikaverpil]

I realize this is a corner case...

So, I have zsh installed in bash on Windows and all is well so far. I tried to also run pure, but I'm getting errors such as this when I cd into a git repository:

~
❯ cd .dotfiles
async_job:zpty:4: no such pty command: prompt_pure
async_job:zpty:4: no such pty command: prompt_pure

~/.dotfiles master
❯

Not sure why. Could it be that I'm missing some prerequisites?

My zsh setup can be seen here. The async and prompt_pure_setup are being created/symlinked by the prompt.zsh script.

Would you mind running the following commands and displaying the output?

❯ zpty -b test cat

❯ zpty -w test hi

❯ zpty -r test
hi

❯ zpty -d test

❯ zpty -L
zpty -b prompt_pure _async_worker -p 94857 -u -n

[fredrikaverpil]

Sure!

zpty -b test cat

zpty: can't open pseudo terminal: exec format error

zpty -w test hi

zpty: no such pty command: test

zpty -r test

zpty: no such pty command: test

zpty -d test

zpty: no such pty command: test

zpty -L

...did not return anything at all.

Ok, so the problem is that your version of zsh is not capable of opening up a zpty instance. There have always been problems on Windows, as can be seen in #141. Although the Babun shell did seem to be capable of opening zpty instances, which does not seem to be the case here.

Is this some special version of zsh? I'm afraid I'm not very familiar with the new Bash@Windows stuff.

[fredrikaverpil]

Aha. No, this is just what you get when you apt-get install zsh, which is what I did. Then I just ran /bin/zsh to enter zsh.

I don't have a good idea on what to do to try to fix this at the moment, but I'll report back if I find anything.

[mafredri]

Alright, then it seems the Windows environment is incompatible with zsh. I would recommend opening an issue with BashOnWindows and perhaps also reporting it on the zsh mailing list.

Sorry I can't be of more help! And also, if you find there's anything we can do to fix this, feel free to re-open.

@mafredri I'll jump over to BashOnWindows. Thanks for taking the time to look into this!
