include a file based on environment variables such as "include ${HOSTNAME}-font.conf"

[benibilme]

I am trying to use same kitty.conf for different computers. I have created platform specific files which the common kitty.conf files include. I use a script to generate necessary symbolic links to platform specific files

For example in kitty.conf

include font.conf

A script links the ${HOSTNAME}-font.conf to font.conf such as font.conf etc.

I really do not want to use a script to do that. Is there a way to that in kitty.conf. I know that env directive. But it seems it does not honor $HOSTNAME env variable.

What I would like to do is following:

include ${HOSTNAME}-font.conf

However above command fails.

Any help much appreciated.

include ${HOSTNAME}.conf works fine but you need to make sure HOSTNAME is defined in whatever environment you are running kitty in. In particular setting it in your shell rc files wont work, since those run *after* kitty starts.

Thank you,

I have not defined $HOSTNAME in any of my rc files. It is available by default. In my terminal, I can echo $HOSTNAME in kitty terminal bash shell, but somehow kitty itself does not see it. I checked via map f1 show_kitty_env_vars.

I added a different variable for not messing with the system settings such as PLATFORM=$(hostnamectl hostname) in .bash_profile, and bound $PLATFORM variable in kitty.conf as include ${PLATFORM}-font.conf, now it works. I do not know why $HOSTNAME does not propagate to kitty.

I wish such a command include $(hostnamectl hostname)-font.conf would be possible in kitty.conf , which would be far cleaner solution for me.

Just because it isnt in your personal rc files doesnt mean its not in one of the system ones. Allowing command execution in conf files makes parsing and loading config slow and non-static. It isnt really worth the tradeoff. If you really want something like that simply make a wrapper script to run kitty in that script use whatever commands you like to generate your config and either directly pass it to kitty via --config or use --override
