While this is not a direct issue with this repo itself, I think documenting this and being searchable here might help people to figure out what to do with this mysterious behaviour.

So things like below similar to the one from current README.md worked with open but not with Chrome for me.

on open location this_URL
	do shell script "emacsclient \"" & this_URL & "\" && open -a Emacs"
end open location

And if you debug this by something like below. You don't really see the difference yet.

on open location this_URL
	do shell script "echo '" & this_URL & "' >> ~/tmp/debug-org-protocol"
end open location

But if you pipe it via base64 you might see a strange difference especially with a long enough this_URL

Try org-protocol://find-file:///Users/my-user/my-folder/my-file with both open and Chrome.

# tail -f ~/tmp/debug-org-protocol

# with `open` - it results in 2 lines - I don't know why

# with Chrome - it prints in one line - expected
b3JnLXByb3RvY29sOi8vZmluZC1maWxlOi8vL1VzZXJzL215LXVzZXIvbXktZm9sZGVyL215LWZpbGUK

However, if you wrap the whole script with zsh now the Chrome's behaviour follows the same as zsh and

on open location this_URL
	do shell script "zsh -c \"echo '" & this_URL & "' | base64 >> ~/tmp/debug-org-protocol\""
end open location

# with `open` - it stays the same
b3JnLXByb3RvY29sOi8vZmluZC1maWxlOi8vL1VzZXJzL215LXVzZXIvbXktZm9sZGVyL215LWZp
bGUK
# with Chrome - it follows `open` now
b3JnLXByb3RvY29sOi8vZmluZC1maWxlOi8vL1VzZXJzL215LXVzZXIvbXktZm9sZGVyL215LWZp
bGUK

Same goes for org-protocol and now it is being recognized with Chrome as well with a code like below.

on open location this_URL
	do shell script "zsh -c 'emacsclient \"" & this_URL & "\" && open -a Emacs'"
end open location

Also, if I used bash instead of zsh, it didn't work.

Hope this is helpful for some people!

Might be obvious to some, but not to me: you have to save org-protocol.app under /Applications for this to work.

Hi thanks first for the repo. I was trying to setup the protocol early today but the script seems not working. I looked into the script and sort of guessed where the problem could be and fixed the problem. I don't know how to contribute to the repo but hopeful this tip can help other users who have non-programming background and are usually clueless when there's no existing working solution readily available on the internet:

Update for Macbook built on AMD chips. homebrew installs software to folder different from usr/bin, to find the actual location of the emacsclient, run brew info emacs to find the path of emacsclient and navigate into the file to get the file path of emacsclient, it's usually under bin folder. After finding the exact location, replace the path stated in the script section.
