Zig 0.16.0 release notes: “Juicy Main” (https://ziglang.org/download/0.16.0/release-notes.html#Juicy-Main)

Zig has really good release notes - comprehensive, detailed, and with relevant usage examples for each of the new features.

Of particular note in the newly released Zig 0.16.0 is what they are calling “Juicy Main” - a dependency injection feature for your program’s main() function where accepting a process.Init parameter grants access to a struct of useful properties:

const std = @import(“std”);

pub fn main(init: std.process.Init) !void { /// general purpose allocator for temporary heap allocations: const gpa = init.gpa; /// default Io implementation: const io = init.io; /// access to environment variables: std.log.info(“{d} env vars“, .{init.environ_map.count()}); /// access to CLI arguments const args = try init.minimal.args.toSlice( init.arena.allocator() ); }
