VimR ignores local Ruby

[polydevuk]

I'm running NeoVim 0.9.1 via MacPorts on Mac OS Ventura 13.3.1 and Ruby 3.22 via $HOME/.rbenv . I have an alias to run VimR with my NeoVim config:

vimr --nvim -u ~/.config/nvim/init.lua

... which mostly works fine but :checkhealth is not regcognising my Ruby and insists on using the system Ruby instead:

mason.nvim [Languages]

• OK: Ruby: ruby 2.6.10p210 (2022-04-12 revision 67958) [universal.x86_64-darwin22]
• WARNING: RubyGem: not available

Ruby provider (optional)

• INFO: Ruby: ruby 2.6.10p210 (2022-04-12 revision 67958) [universal.x86_64-darwin22]

• INFO: Host: /Users/gmac/.rbenv/shims/neovim-ruby-host

• ERROR: Command error (job=11, exit code 1): gem list -ra '^neovim$' (in '/Users/gmac')

• ERROR: Failed to run: gem list -ra ^neovim$

My NeoVim :checkhealth shows no errors and respects the Ruby I have configured:

mason.nvim [Languages]

• OK Ruby: ruby 3.2.2 (2023-03-30 revision e51014f9c0) [x86_64-darwin21]
• OK RubyGem: 3.4.13

Ruby provider (optional)

• Ruby: ruby 3.2.2 (2023-03-30 revision e51014f9c0) [x86_64-darwin21]
• Host: /Users/gmac/.rbenv/shims/neovim-ruby-host
• OK Latest "neovim" gem is installed: 0.9.0

I don't know if this is related but there is also an intit file issue listed by VimR :checkhealth:

Configuration

• WARNING: Missing user config file: /Users/gmac/.config/nvim/init.vim

My config is: /Users/gmac/.config/nvim/init.lua

Do you have this line in your config? I just checked with it and it worked fine.

let g:ruby_host_prog = '~/.rbenv/versions/3.2.2/bin/neovim-ruby-host'

For more information :help g:ruby_host_prog
