Support for WSL users using Win32 GPG binaries

[AlexanderAllen]

Hi @wdhongtw,

Love your extension. Recently I switched from using 'nix to manage GPG records to native Windows binaries so I could use a smart card. This extension works perfectly fine in WSL as long as GPG binaries are installed in WSL. It's a whole lotta different story when (as a VSCode WSL user) those binaries are located in Windows.

These two PRs I did internally in my fork address (most) of the cross-compatibility issues I picked up: AlexanderAllen#6, AlexanderAllen#10 (trigger warning, it's a significant rewrite of the gpg module).

However, after those two PRs Assuan rightfully refuses to talk to a naked Windows socket path. That's not exactly a priority for me because the extension is working for my use case, but the ticket is open nevertheless and chances are I might take a bite at it, at some point.

Just thought I'd dropped some visibility into the work I did for supporting WSL users.

I'm not sure about issuing a PR against the main repo quite yet, at least not until cross platform compatibility is in a more production-ready state (see Assuan, above).

But I can drop an update here and there in this ticket as I complete my own PRs, if you'd like.

Cheers!
