# Humane Units [![Build Status](https://travis-ci.org/dustin/go-humanize.svg?branch=master)](https://travis-ci.org/dustin/go-humanize) [![GoDoc](https://godoc.org/github.com/dustin/go-humanize?status.svg)](https://godoc.org/github.com/dustin/go-humanize)
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](https://godoc.org/github.com/dustin/go-humanize) 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:
```go 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:
```go 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][odisc] where a user wanted to be able to label ordinals.
0 -> 0th 1 -> 1st 2 -> 2nd 3 -> 3rd 4 -> 4th [...]
Example:
```go 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:
```go fmt.Printf("You owe $%s.\n", humanize.Comma(6582491)) // You owe $6,582,491. ```
## Ftoa
Nicer float64 formatter that removes trailing zeros.
```go 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][sinotation].
Example:
```go humanize.SI(0.00000000223, "M") // 2.23 nM ```
## English-specific functions
The following functions are in the `humanize/english` subpackage.
### Plurals
Simple English pluralization
```go 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:
```go 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 ```
