thread 'main' panicked at 'no entry found for key', libcore/option.rs:917:5

Thank you for reporting this.

I have never seen this. Could you please provide a little bit more information?

What kind of files does this fail on? Could you provide one of those files for further debugging?

Also, could this be related to rust-lang/rust#44863 ? Could you try to call cargo clean and build bat again?

Also, to make the backtrace more helpful, it would be great if you could build in debug mode (cargo install -f --debug) and run RUST_BACKTRACE=1 bat .. again.

Ok, I know what has been causing this - you probably did not install a syntax highlighting theme?

Please follow the instructions here.

The panic should not appear again. I have turned it into a normal error message.

Syntax highlighting theme is installed.

Can you please provide detailed instructions how clean and install are supposed to be done? I tried

git clone https://github.com/sharkdp/bat.git
cd bat
cargo clean
cargo install -f --debug bat
RUST_BACKTRACE=1 bat README.md

Test file is this repositories' README.md

I'm pretty sure this is not the latest version of bat (the line numbers don't match). Could you please make sure to git pull again?

Also, please post the output of

ls -alh ~/.config/bat/themes/Default.tmTheme

It should be a valid Sublime Theme or a symlink to one.

Oh, damn - this took me a while to figure out 😄
You are calling cargo install -f bat instead of cargo install -f which installs bat from crates.io (instead of from the current directory). The version on crates.io is outdated, I will update it soon.
