"Invalid method: nvim_cmd" at startup

Check if applicable

I reproduced the issue with an empty Neovim configuration (init.vim or init.lua)

Describe the bug

Just installed ShadowVim and tried to run it for the first time. I get the error "Invalid method: nvim_cmd". Ignore, Reset, and Quit all do the same thing. The message appears three to four times and then stops. It appears each time I move my cursor to a new pane in Xcode.

How to reproduce?

Start ShadowVim
Get error

Neovim configuration

Still have the issue with an empty config

Run :checkhealth for more info

ShadowVim requires Neovim 0.8. I might add something to check the version during runtime to get a more helpful error.

Curious. When I ran nvim --version it claimed I was on 0.8.3. ShadowVim worked after I ran brew upgrade though. Maybe I had more than one version installed or something. Better error could definitely help.

Thanks!

ShadowVim is not run with the PATH from your shell profile (because .app from Finder), so maybe you ran a different nvim binary. I explicitly added to PATH the bin directories of popular package managers:

ShadowVim/Sources/Toolkit/Extensions/Swift/Process.swift

Lines 59 to 65 in 499e522

    
           env["PATH"] = "\(path):\(home)/bin" 
        
               // MacPorts: https://guide.macports.org/#installing.shell.postflight 
        
               + ":/usr/local/bin" 
        
               // Homebrew: https://docs.brew.sh/FAQ#why-should-i-install-homebrew-in-the-default-location

I added this quickly: #27

(The VersionTests were generated with copilot.vim thanks to ShadowVim 😉)
