How to Write a Redis Module in Zig
Blog post from Redis
Redis supports modules, which are custom extensions that add new commands, data types, and functionalities to a Redis database. Writing a module can be done using C, but this requires setting up a new C project and dealing with cross-platform compilation issues. Zig, a new language developed by Andrew Kelley, is a more modern alternative that allows writing fully C ABI compatible binaries while providing additional safety features such as advanced error checking and generics. Zig makes it easy to write Redis modules by allowing the import of C header files directly or translating them to Zig using the `translate-c` command. The translation process involves changing type signatures to spare unnecessary optional unwrapping, and the resulting code is straightforward and easy to read. With Zig, building a Redis module can be done with minimal effort, even cross-compilation for 64-bit Linux is supported in a single command.
