Zig-fmtHelper

Includes several std.fmt helpers, including:

• bytes: automatically format large byte values in KB, MB, GB, TB, etc.
• si: automatically format large or small values using SI unit prefixes.

Installation

Add to your build.zig.zon:

$ zig fetch --save git+https://github.com/bcrist/Zig-fmtHelper

Add to your build.zig:

pub fn build(b: *std.Build) void {
    const fmt_module = b.dependency("fmt_helper", .{}).module("fmt");

    //...

    const exe = b.addExecutable(.{
        //...
    });
    exe.root_module.addImport("fmt", fmt_module);

    //...
}

Example Usage

pub fn print_stats(some_number_of_bytes: usize, some_number_of_nanoseconds: usize) !void {
    std.io.getStdOut().writer().print(
        \\   some number of bytes: {}
        \\   some duration: {}
        \\
    , .{
        fmt.bytes(some_number_of_bytes),
        fmt.si.ns(some_number_of_nanoseconds),
    });
}

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

Possible output:

   some number of bytes: 3 KB
   some duration: 47 ms
