PlugInstall is trying to clone into a path composed of cygwin + windows paths concatenated together?

[mgregory22]

I'm having a bizarre problem with some part of vim-plug concatenating paths together, and it's preventing the plugins from installing:

Any ideas where this extra "/home/Matt/dotfiles/vimfiles/plugged/" string is coming from?

Well, the git is cygwin git, so I guess vim-plug is presuming I'm using Windows git?

[janlazo]

Yes.
msys2 git can handle Windows-style and Unix-style paths.
Cygwin git always assumes Unix-style paths.
Question is which Vim are you using? Native windows (from the website or win32 releases), msys2 Vim, or cygwin Vim?

[mgregory22]

I use Windows x64 Gvim and Cygwin shell and utilities. I'm not particularly attached to cygwin other than it took awhile to get it working the way I want and I've been using it a long time. I suppose I should switch to the linux subsystem, but I haven't really had time to figure it out.

[mgregory22]

It's cool, I can use msys2 git just for vim-plug. I have it on my system, but I disabled it by removing it from my path. I can just add it to the path before running PlugUpdate or whatever.

[janlazo]

Did it work?

[mgregory22]

Yeah, it worked. So, I guess the issue is that vim-plug is incompatible with Cygwin git. I was going to try and fix it, but I don't think it's currently possible to determine if git is the cygwin git. If you could determine that, then you could run cygpath on the paths to convert them to cygwin paths before passing them to git. At least I think that would fix it.

[janlazo]

What's the output of git --version for Cygwin git and Msys2 git on your system?

[mgregory22]

Cygwin git:

git version 2.15.0

Msys2 git:

git version 2.9.2.windows.1

[janlazo]

Cygwin git doesn't have windows in the version string so you can use cygpath on it.
Problem then is which cygpath to use.

[mgregory22]

Oh, you think the process of elimination would be enough?

Which cygpath? I'm not sure what you mean.

[janlazo]

You can't mix up the cygpath and git on each msys2/cygwin installation.
You can use where.exe on cmd.exe to check which one comes up first in PATH.

[mgregory22]

Well there is no cygpath for msys2, is there?

[janlazo]

There is one each on my system from https://git-for-windows.github.io/, mingw, and cygwin.
