Powerlevel10k: Issues with ${var:A} expansion and snap

[georgijd]

I was having issues with the go_version segment not displaying anything and after some debugging, I found the culprit. It seems that the prompt_go_version function doesn't correctly pick up the Go version (https://github.com/romkatv/powerlevel10k/tree/master/internal/p10k.zsh#L2025-L2027)
The root cause is the variable expansion in https://github.com/romkatv/powerlevel10k/tree/master/internal/p10k.zsh#L2251.

Because go was installed with snap the ${commands[go]:A} expansion resolved to snap and, naturally, the output of that command doesn't contain the actual go version.

$ echo ${commands[go]}
/snap/bin/go

$ echo ${commands[go]:A}
/usr/bin/snap

$ ${commands[go]:A} version
snap    2.43.3
snapd   2.43.3
series  16
ubuntu  19.10
kernel  5.3.0-40-generic

Installing go manually works as expected.

I'm not sure if this is a snap or realpath issue, but either way I guess p10k could handle that edge case. I guess this affects any prompt segments which rely on executing snap installed commands with that variable expansion syntax.

Thanks for the report! Fixed. Please update powerlevel10k and try again. Let me know whether it works for you now.

Thank you for the _prompt_ fix! It's working now :)
