Installed through brew, Neovim only launches when opening oni from command line

[kylepollina]

Oni Version: 0.3.2.1
Neovim Version (Linux only):
Operating System: macOS 10.14.1

Issue: Neovim does not load when I open Oni from the Applications folder, but it runs correctly when I launch Oni from the command line.

Expected behavior: Neovim launches when I run Oni by clicking on the icon

Actual behavior: Neovim does not launch when I run Oni by clicking on the icon. Neovim does launch when I run oni from the command line.

Steps to reproduce: Install Oni from homebrew, running 'brew cask install oni'
Launching Oni from the command line, Oni works as it is expected. However if I launch Oni by clicking on the icon from the Applications folder, it tells me Neovim is unable to launch.

Hello and welcome to the Oni repository! Thanks for opening your first issue here. To help us out, please make sure to include as much detail as possible - including screenshots and logs, if possible.

I'm also having this problem.

As I've not got a Mac, do @bryphe or @Akin909 have any input on this?

Its possible its similar to the other 10.14 issues we've been having, though I'd be surprised why there is a difference loading via the commandline and the app icon. (Though technically I think they run different scripts?)

My first guess is that it is a pathing issue...I don't know where to look in oni to see logs and such though...

@dsummersl perhaps check the chrome console logs first? Help -> Developer Tools -> Console.

Thanks so much for that...I see this in the dev console:

I verified that the path to nvim does exist...and it appears to have the same logs (same nvim used) in the developer console when I launch from my command line (but without the error).

I see this problem - including log line about crashing Neovim even when I launch Oni from command line using /Applications/Oni.app/Contents/MacOS/Oni

I believe this is another duplicate of #2396 (the other one being my own).

Thanks all for reporting this! I was able to repro and found the issue - we're hitting this issue: neovim/neovim#9134 (fixed here neovim/neovim@57acfce)

It seems that previously we were getting the LANG environment variable set, but with Mojave we're not anymore. Thanks @jordan-arenstein for finding the bug and @mhinz for the fix on the Neovim side 👍

I'll release a new build of Oni with a workaround - it'll set the LANG variable if it isn't set. It's not ideal because it's hardcoded to en_us.UTF-8, but I also have a configuration key that can override this:

"environment.additionalVariables": {
  "LANG": "zh_CN.UTF-8",
},
