Zig 0.16.0 release notes: "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()
);
