Fully working version has moved to ~rjk/tg - Zig program to read/write macos finder tags - sourcehut git.

I decided to learn Home ⚡ Zig Programming Language and eschew Rust. I needed a Zig starter project. I wanted a way to read/write the metadata tags on files on MacOS. Hence tg: a simple program to tag.

The purpose of this program is largely pedagogical. (I.e. I don't really know what I'm doing in this code.) With it I learned:

• how to add a Zig package to an existing project by editing the .zon and build.zig
• how to use a C API from Zig
• how to wrap (maybe incorrectly) a C system call
• some thoughts on memory management and the passing of allocators.
• running tests not in the "root" source
• build.zig can also be debugged with printfs.

Shows the metadata keys on a list of files.
