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);
//...
}
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");
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
