How can I programmatically retrieve the version of Zig?

Question

How do I programmatically retrieve the version of zig?. In python I could do it by using sys module.

>>> import sys
>>> sys.version

How can I achieve the same thing in zig?

Answer 1

Use builtin.zig_version. That returns SemanticVersion.

const std = @import("std");
const builtin = @import("builtin");

pub fn main() !void {
    std.log.info("Zig version: {}", .{ builtin.zig_version });
}

Prints:

$ zig build run
info: Zig version: 0.12.0-dev.587+eb072fa52
