BUG REPORT

The "vim.useSystemClipboard": false parameter screws up VscodeVim's behaviour. Not entirely sure why, but I'm happy to provide additional context as necessary.

Opened code from Terminal, and iTerm2 just to check; found the same error.

Environment:

• VSCode Version: 1.16.1
• VsCodeVim Version: 0.10.0
• OS: macOS 10.12.6

What happened:

Here' a gif summarizing the workflow. tl;dr: Flipping this parameter to true makes yy, dd, etc. not work.

What did you expect to happen:
I expected text to be copied to the System Clipboard, and for the default Vim behaviour to work. Neither does.

How to reproduce it:
This is a vanilla install on a new machine. Already restarted a few times.

Open to suggestions.

@Vvkmnn It's likely that the library we're using for interfacing with the system clipboard is crashing when you try to do yy.

Fair enough. I'll try and use other registers for now.

Would you recommend building from source or trying the Insider version? Not sure that'd fix it; just thinking out loud.

I could also try logging the event if that helps trace it.

@xconverge I seem to remember some other person had this problem. Do you remember how he fixed it?

Tore away at my config until I got it working; turns out it wasn't this plugin's fault at all. Sorry guys.

The true issue appeared to be launching code . from inside a Tmux session. Electron might mangle up what clipboard is allowed to refer to when piped through it:

microsoft/vscode#36755

FIX: Just launch Vscode outside Tmux (or help figure out the error: microsoft/vscode#24112)

Keep up the good work. ✌️
