addPackagePath is not present in zig 0.11:

/home/lyh/Documents/CS/compiler/yula/yula/build.zig:35:8: error: no field or member function named 'addPackagePath' in 'Build.Step.Compile'
    exe.addPackagePath("pcre", "vendor/libpcre.zig/src/main.zig");
    ~~~^~~~~~~~~~~~~~~
/home/lyh/.zvm/0.11.0/lib/std/Build/Step/Compile.zig:1:1: note: struct declared here
const builtin = @import("builtin");

    remaining reference traces hidden; use '-freference-trace' to see all reference traces

So readme should also be updated. But TBH there should be a way to integrate tightly with zon package manager instead.

I admit I only updated the library part of the code and not the build.zig

I'm willing to help, so I fork your fork and commit on it?

Also, even if I fix it on my own end I got errors telling me zig can't find pcre package, which I didn't know how to fix.

I've pulled in the difference of @mattnite's #12 as 101d81c, and we have a flake.nix now too. Thank you all!
