Humane Units Build Status GoDoc

Just a few functions for helping humanize times and sizes.

go get it as github.com/dustin/go-humanize, import it as "github.com/dustin/go-humanize", use it as humanize.

See godoc for complete documentation.

Sizes

This lets you take numbers like 82854982 and convert them to useful strings like, 83 MB or 79 MiB (whichever you prefer).

Example:

fmt.Printf("That file is %s.", humanize.Bytes(82854982)) // That file is 83 MB.

Times

This lets you take a time.Time and spit it out in relative terms. For example, 12 seconds ago or 3 days from now.

Example:

fmt.Printf("This was touched %s.", humanize.Time(someTimeInstance)) // This was touched 7 hours ago.

Thanks to Kyle Lemons for the time implementation from an IRC conversation one day. It's pretty neat.

Ordinals

From a mailing list discussion where a user wanted to be able to label ordinals.

0 -> 0th
1 -> 1st
2 -> 2nd
3 -> 3rd
4 -> 4th
[...]

Example:

fmt.Printf("You're my %s best friend.", humanize.Ordinal(193)) // You are my 193rd best friend.

Commas

Want to shove commas into numbers? Be my guest.

0 -> 0
100 -> 100
1000 -> 1,000
1000000000 -> 1,000,000,000
-100000 -> -100,000

Example:

fmt.Printf("You owe $%s.\n", humanize.Comma(6582491)) // You owe $6,582,491.

Ftoa

Nicer float64 formatter that removes trailing zeros.

fmt.Printf("%f", 2.24)                // 2.240000
fmt.Printf("%s", humanize.Ftoa(2.24)) // 2.24
fmt.Printf("%f", 2.0)                 // 2.000000
fmt.Printf("%s", humanize.Ftoa(2.0))  // 2

SI notation

Format numbers with SI notation.

Example:

humanize.SI(0.00000000223, "M") // 2.23 nM

English-specific functions

The following functions are in the humanize/english subpackage.

Plurals

Simple English pluralization

english.PluralWord(1, "object", "") // object
english.PluralWord(42, "object", "") // objects
english.PluralWord(2, "bus", "") // buses
english.PluralWord(99, "locus", "loci") // loci

english.Plural(1, "object", "") // 1 object
english.Plural(42, "object", "") // 42 objects
english.Plural(2, "bus", "") // 2 buses
english.Plural(99, "locus", "loci") // 99 loci

Word series

Format comma-separated words lists with conjuctions:

english.WordSeries([]string{"foo"}, "and") // foo
english.WordSeries([]string{"foo", "bar"}, "and") // foo and bar
english.WordSeries([]string{"foo", "bar", "baz"}, "and") // foo, bar and baz

english.OxfordWordSeries([]string{"foo", "bar", "baz"}, "and") // foo, bar, and baz
You can’t perform that action at this time.
