Cannot open ".tex" or "Makefile" by double-clicking on macOS finder

[anjos]

Describe the bug
I setup kitty to be able to open files by double-clicking on the macOS finder. It launches kitty and my $EDITOR (which is Neovim). This works for most filetypes, except a few. Most notably ".tex" or "Makefile".

A clear and concise description of what the bug is.
Kitty complains with {'msg': 'Unknown URL type, cannot open:\n file:///Users/andre/work/biosignal/slides/vital-signs/intro.tex'}

To Reproduce
Steps to reproduce the behavior:

1. Setup macOS to open .tex or Makefile files with kitty (to setup file associations, I used duti - brew install duti)
2. Double-click on a .tex file.
3. See the window come up and then go away

Further information
To debug this problem, I started kitty with kitty --dump-commands. I clicked on the file I wanted to open, and observed the output. At first, it stated:

draw No kitten named show_error

Would that kitten exist, that would have showed me the error, I guess. After implementing a sketchy kitten called show_error.py, I got to the message above about the unknown URL type.

So, I guess there are actually 2 issues? a) a missing show_error kitten somewhere, and b) a mechanism to associate filetypes with Kitty? Or may be I am doing something wrong?

Additional context
I tried this, and the results are the same.

Thanks for this fix, @kovidgoyal - that was quick!

What about the show_error issue that is somewhat related? Can you either provide a default kitten for that with kitty, or document how to provide one? Or should I open another issue for this?

[kovidgoyal]

its already fixed.
