What steps will reproduce the bug?

I'm using tmux.

When calling bat it shows this error:

[bat error]: The binary caches for the user-customized syntaxes and themes in '/home/fschoenm/.cache/bat' are not compatible with this version of bat (0.24.0). To solve this, either rebuild the cache (bat cache --build) or remove the custom syntaxes/themes (bat cache --clear).

However, running bat cache --build shows another error:

error: unexpected argument '--build' found

  tip: to pass '--build' as a value, use '-- --build'

Usage: bat <FILE>...

For more information, try '--help'.

bat cache --clear also does not work. There doesn't seem to be a subcommand cache.

What happens?

It doesn't work, no idea why.

What did you expect to happen instead?

No idea what is even the problem. Why cannot bat clear its own cache if it needs to with a new version?

How did you install bat?

Config file

# This is `bat`s configuration file. Each line either contains a comment or
# a command-line option that you want to pass to `bat` by default. You can
# run `bat --help` to get a list of all possible configuration options.

# Specify desired highlighting theme (e.g. "TwoDark"). Run `bat --list-themes`
# for a list of all available themes
--theme="Catppuccin-macchiato"

# Enable this to use italic text on the terminal. This is not supported on all
# terminal emulators (like tmux, by default):
#--italic-text=always

# Uncomment the following line to disable automatic paging:
#--paging=never

# Uncomment the following line if you are using less version >= 551 and want to
# enable mouse scrolling support in `bat` when running inside tmux. This might
# disable text selection, unless you press shift.
#--pager="less --RAW-CONTROL-CHARS --quit-if-one-screen --mouse"

# Syntax mappings: map a certain filename pattern to a language.
#   Example 1: use the C++ syntax for .ino files

I was running the above in tmux. When running without tmux, everything works. No idea why, so maybe you can find it out. I edited the bug report above accordingly :)

No idea what is even the problem. Why cannot bat clear its own cache if it needs to with a new version?

We have an issue tracking this :) https://github.com/sharkdp/bat/issues/2085

I have never used tmux, so forgive this wild guess... Is the bat run from within tmux the same version as the bat run from outside tmux?

Yeah pretty sure it was the same.

Is there any chance you have a file named cache in the directory you were executing the command from while within tmux? If there is, bat will disable the cache subcommand so it can print the file named cache.

That's probably it. I know it's a terrible UX. We should have never introduced the cache subcommand. But I'm not sure if we will get rid of it now. Closing for now.
