[paulsmith]

Adds syntax support for source code for the Zig programming language.

Thank you very much for your contribution!

I added the instructions for adding syntax tests just today, and I did forget to mention a peculiarity when creating syntax tests for a new syntax. You actually first need a version of bat that has the new Zig syntax builtin. This means that you have to run bash assets/create.sh and then recompile bat. I will update the tests for you (and update the documentation).

@paulsmith Awesome to see Zig support land. However I just compiled from the main branch and Zig support not available. bat -L | rg -i zig doesn't return anything and

bat -l zig ~/Downloads/hello.zig
[bat error]: unknown syntax: 'zig'

Does Zig support need to be enabled in some way? Any chance it isn't working as I'm compiling with musl - cargo build --release --verbose --target x86_64-unknown-linux-musl. I've confirmed Zig support isn't working on MacOS and Linux aarch64 too.

@moderation Until we release the next version, you need to manually generate the new builtin syntax set:

• make sure that all submodules are checked out as well
• compile bat
• run bash assets/create.sh
• compile bat again.
