Humane Units

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" for the original one, "github.com/yaguetto/go-humanize" for my forked version with dots, use it as humanize.

See godoc for complete documentation.

Dots

Dots for us from Brazil do not feel left out

1,000.00 -> 1.000,00
1,000,000,000.00 -> 1.000.000.000,00
-100,000.00 -> -100.000,00

Example:

fmt.Printf("You owe R$%s.\n", humanize.Dotf(6582491.69)) // You owe R$6.582.491,69

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
