Differences between launch kitten and clone-in-kitty, clone-in-kitty confirmation, global user variables

[gvlassis]

Hello!

1. What are the actual differences between the kitten @ launch --cwd current --copy-env and clone-in-kitty. I know that the first one is a kitten and the second a bash function, but I was wondering about the underlying differences and their effects (e.g. does clone-in-kitty read the .bashrc like launch?)
2. Is there any way to disable the clone-in-kitty confirmation (similar to confirm_os_window_close)?
3. I want my neovim theme to mirror my kitty theme. Is there any way for external applications to query info like this directly from kitty? I am aware of user variables, but they are defined for tabs, not kitty's configuration. The ideal solution for me would be to have something like theme=darkula in kitty.conf, and then read it directly from kitty like you read user variables (i.e. something like "global" user vars).

These are all answered in the docs. 1. neither sources .bashrc 2. allow_cloning 3. There are standard terminal escape codes you can use in any terminal to query information about colors, use them. Or use kitty remote control which has a get-colors command

Oh and the main difference between launch and clone is clone access live environment variable --copy-env accesses only the env vars set when the process was launched. See the docs of --copy-env

1. In my .bashrc file I have a print statement which is run when I do kitten @ launch/clone-in-kitty (I can see the output of print, which is different for every invocation). How does this statement run if neither sources .bashrc? And if they do not run .bashrc what are they doing behind the scenes?
2. allow_cloning is exactly what I was looking for. Do not know why I did not see it. Thanks a lot!
3. The escape codes/get-colors are about getting colors (with predefined names, like background etc.). I want to retrieve arbitrary strings (e.g. var='test123'). Essentially, I am looking for something like "global" user vars (user vars for all the tabs). Alternatively, how would you go about setting a specific user var in every tab launched in kitty.conf?
4. Wait, this contradicts the docs. The launch action cannot copy live env vars, the launch kitten can (according to the docs+my experiments).

bash sources bashrc

Set an env var

Yes, that's what I said. --copy-env does not access live env vars clone-in-kitty does.
