How do I make NeoVim my default text/code editor? - macos

Question

Is there a way to make NeoVim as default text/code editor (without any bad side effects) ?Trust me, I looked to lots of StackOverflow question/answers and tried a few things but nothing worked for me.
Note: I'm on macOS Big Sur (version 11.2.1). What I want is when I click on files to open in NeoVim.
--> For example, in ~/.zshrc (and added to ~/.bash_profile also just in case) I have:
Note: zsh is my default shell
alias nvim=$HOME/nvim-osx64/bin/nvim
export EDITOR="nvim"
export VISUAL="nvim"
When I do set in Terminal it shows:
EDITOR=nvim
VISUAL=nvim
And yes, I quit and started the terminal (I'm using iTerm2). I even reboot.
--> I will place my $PATH here just in case it has anything to do it that. When I do echo $PATH it shows:
--> And, just in case someone suggests:
I can't Select a File > Open With... and select NeoVim as default text editor, since that option doesn't show and I can't do Choose Other since I can't select NeoVim in that way.
If anyone needs more information, please say and I will edit the question with that info. Thanks!

Answer 1

Setting variables in the terminal will not affect the GUI file associations. To do that you have to change the OS's file associations.
Though it appears to be a small project and unsupported, I've had a good experience using duti. It's a wrapper around the Apple file extension API. The configuration did take me a minute to figure out. I'll post it if I can find it.

After a while I found the answer to my own question, here it is how you can set NeoVim in Mac as the default text editor. Now, you will be able click on files and opening them in NeoVim:
Some people recommended me to have a look at the follow links:
https://gist.github.com/Huluk/5117702
https://superuser.com/questions/139352/mac-os-x-how-to-open-vim-in-terminal-when-double-click-on-a-file
That didn't work for me but it served as a reference to look up related topics (automator + neovim).
After a while, I discover this blog:
https://blog.schembri.me/post/neovim-everywhere-on-macos/
Go and have a look at the blog, but here it is how you do it:
Launch Automator (Finder -> Applications -> Automator)
New Document -> Choose a type for your document: Application
In Actions search for Run AppleScript and drag that to where it says something like "Drag actions here..."
Delete the default example of AppleScript
Copy and Paste the code in the blog (where it says NeoVim.app) to where it previous had the default code
Save the new Automator app (save as aplicattion format). Save it in the Applications folder
Right-Click a file type you wish to open every time you click on them (e.g. .php file). Select Get Info or do cmd + i, it will open informations about that file. Scroll to wher it says Open With and select Other. Then just go to Aplicattions folder and select your new NeoVim "app".
Do the same to other file types if you wish.
You can now double click on your PHP files (or others if you did the same) and open them in NeoVim. Enjoy!
Note: You really need to do Right-Click, Get Info and look for Open With to change in all files with that extension. If you skip Get Info and just Right-Click + Open With, it will only work for that specific file...
This is the code from the blog:
on run {input, parameters}
set cmd to "nvim"
if input is not {} then
set filePath to POSIX path of input
set cmd to "nvim \"" & filePath & "\""
end if
tell application "iTerm"
create window with default profile
tell the current window
tell the current session to write text cmd
end tell
end tell
end run
This would open a new window even if you already had one open.
I change it so that it would open in a tab:
on run {input, parameters}
set cmd to "nvim"
if input is not {} then
set filePath to POSIX path of input
set cmd to "nvim \"" & filePath & "\""
end if
tell application "iTerm"
tell the current window
create tab with default profile
tell the current session to write text cmd
end tell
end tell
end run
Note: I'm using iTerm2. If you are using another Terminal Emulator, change where it says iTerm to the name of your terminal...

For anyone using Kitty on MacOS, I found a pretty simple way to accomplish this using the remote control feature.
First you need the following set in your kitty.conf:
allow_remote_control yes
listen_on unix:/tmp/mykitty
Using Automator like in #DGF's answer, I created an Application with the "Run Shell Script" action, and this is the script:
if [ -z "$(pgrep kitty)" ]
then
open /Applications/kitty.app
sleep 3 # allow ample time to startup and start listening
fi
/usr/local/bin/kitty # --to=unix:/tmp/mykitty-$(pgrep kitty) launch --type=os-window nvim "$#"
Save that as an application somewhere, and select it from "Open with"!
Note: to be honest, the logic to handle starting up kitty if it's not already running is a little flaky. But it seems to work great when kitty is already running, which of course it is most of the time for me. Also, it doesn't work at all if kitty is running but has no windows. :\

Choose nvim as the default application by means of a txt file sub-menu like here with Preview for PDFs:
