This PR switches the Nomad repository from using govendor to Go modules for managing dependencies. Aspects of the Nomad workflow remain pretty much the same. The usual Makefile targets should continue to work as they always did. The API submodule simply defers to the parent Nomad version on the repository, keeping the semantics of API versioning that currently exists.

# 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://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
|
|
```
