# Humane Units [](https://travis-ci.org/dustin/go-humanize) [](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://pkg.go.dev/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
|
||||
```
