gnvim not working

[philk]

The new gnvim script (which I'm super excited about) doesn't seem to be working for me. It attempts to start Neovim.app but the window just pops up and immediately closes. It seems to have something to do with the new --cwd $PWD arg since open -a Neovim --args /absolute/filename works fine.

Here's what I see in Console.app when I try running gnvim:

10/30/15 11:17:29.358 AM launchservicesd[83]: SecTaskLoadEntitlements failed error=22
10/30/15 11:17:29.361 AM launchservicesd[83]: SecTaskLoadEntitlements failed error=22
10/30/15 11:17:29.768 AM appleeventsd[55]: SecTaskLoadEntitlements failed error=22

A quick bit of Googling also makes it seem like it may have something to do with security permissions related to El Capitan's rootless mode but I couldn't find any fixes. Putting this out there to see if anyone else has any solutions.

Bizarre! Can you reproduce it in a debugger and post a stack trace? E.g.

lldb build/Neovim.app/Contents/MacOS/Neovim -- --args --cwd $PWD somefile
r
(then, if it crashes)
bt

Also, I suppose the script would get confused if PWD wasn't set, though I can't see how that would happen. echo $PWD gives some output, right?

Also try running Neovim with -u NONE to disregard your local config

I can also see how this might happen if Neovim.app is old and hadn't been recompiled since the --cwd flag was added, i.e. if you updated to the commit with gnvim in it but didn't run make again.

After rebuilding from source (as opposed to brew reinstall neovim-dot-app --HEAD) it seems to be working so problem solved I guess 🙃

Weirdness with lldb though:

Hm. I know we do ignore SIGPIPE so maybe that's just LLDB picking up on it anyway... if this causes problems I'll look into it but I'm guessing it's benign.
