Locales is a set of locales generated from the Unicode CLDR Project which can be used independently or within an i18n package; these were built for use with, but not exclusive to, Universal Translator.

Features

  • [x] Rules generated from the latest CLDR data, v31.0.1
  • [x] Contains Cardinal, Ordinal and Range Plural Rules
  • [x] Contains Month, Weekday and Timezone translations built in
  • [x] Contains Date & Time formatting functions
  • [x] Contains Number, Currency, Accounting and Percent formatting functions
  • [x] Supports the "Gregorian" calendar only ( my time isn't unlimited, had to draw the line somewhere )

Full Tests

I could sure use your help adding tests for every locale, it is a huge undertaking and I just don't have the free time to do it all at the moment; any help would be greatly appreciated!!!! please see issue for details.

Installation

Use go get

go get github.com/go-playground/locales

NOTES

You'll notice most return types are []byte, this is because most of the time the results will be concatenated with a larger body of text and can avoid some allocations if already appending to a byte array, otherwise just cast as string.

Usage

package main

import (
    "fmt"
    "time"

    "github.com/go-playground/locales/currency"
    "github.com/go-playground/locales/en_CA"
)

func main() {

    loc, _ := time.LoadLocation("America/Toronto")
    datetime := time.Date(2016, 02, 03, 9, 0, 1, 0, loc)

    l := en_CA.New()

    // Dates
    fmt.Println(l.FmtDateFull(datetime))
    fmt.Println(l.FmtDateLong(datetime))
    fmt.Println(l.FmtDateMedium(datetime))
    fmt.Println(l.FmtDateShort(datetime))

    // Times
    fmt.Println(l.FmtTimeFull(datetime))
    fmt.Println(l.FmtTimeLong(datetime))
    fmt.Println(l.FmtTimeMedium(datetime))
    fmt.Println(l.FmtTimeShort(datetime))

    // Months Wide
    fmt.Println(l.MonthWide(time.January))
    fmt.Println(l.MonthWide(time.February))
    fmt.Println(l.MonthWide(time.March))
    // ...

    // Months Abbreviated
    fmt.Println(l.MonthAbbreviated(time.January))
    fmt.Println(l.MonthAbbreviated(time.February))
    fmt.Println(l.MonthAbbreviated(time.March))
    // ...

    // Months Narrow
    fmt.Println(l.MonthNarrow(time.January))
    fmt.Println(l.MonthNarrow(time.February))
    fmt.Println(l.MonthNarrow(time.March))
    // ...

    // Weekdays Wide
    fmt.Println(l.WeekdayWide(time.Sunday))
    fmt.Println(l.WeekdayWide(time.Monday))
    fmt.Println(l.WeekdayWide(time.Tuesday))
    // ...

    // Weekdays Abbreviated
    fmt.Println(l.WeekdayAbbreviated(time.Sunday))
    fmt.Println(l.WeekdayAbbreviated(time.Monday))
    fmt.Println(l.WeekdayAbbreviated(time.Tuesday))
    // ...

    // Weekdays Short
    fmt.Println(l.WeekdayShort(time.Sunday))
    fmt.Println(l.WeekdayShort(time.Monday))
    fmt.Println(l.WeekdayShort(time.Tuesday))
    // ...

    // Weekdays Narrow
    fmt.Println(l.WeekdayNarrow(time.Sunday))
    fmt.Println(l.WeekdayNarrow(time.Monday))
    fmt.Println(l.WeekdayNarrow(time.Tuesday))
    // ...

    var f64 float64

    f64 = -10356.4523

    // Number
    fmt.Println(l.FmtNumber(f64, 2))

    // Currency
    fmt.Println(l.FmtCurrency(f64, 2, currency.CAD))
    fmt.Println(l.FmtCurrency(f64, 2, currency.USD))

    // Accounting
    fmt.Println(l.FmtAccounting(f64, 2, currency.CAD))
    fmt.Println(l.FmtAccounting(f64, 2, currency.USD))

    f64 = 78.12

    // Percent
    fmt.Println(l.FmtPercent(f64, 0))

    // Plural Rules for locale, so you know what rules you must cover
    fmt.Println(l.PluralsCardinal())
    fmt.Println(l.PluralsOrdinal())

    // Cardinal Plural Rules
    fmt.Println(l.CardinalPluralRule(1, 0))
    fmt.Println(l.CardinalPluralRule(1.0, 0))
    fmt.Println(l.CardinalPluralRule(1.0, 1))
    fmt.Println(l.CardinalPluralRule(3, 0))

    // Ordinal Plural Rules
    fmt.Println(l.OrdinalPluralRule(21, 0)) // 21st
    fmt.Println(l.OrdinalPluralRule(22, 0)) // 22nd
    fmt.Println(l.OrdinalPluralRule(33, 0)) // 33rd
    fmt.Println(l.OrdinalPluralRule(34, 0)) // 34th

    // Range Plural Rules
    fmt.Println(l.RangePluralRule(1, 0, 1, 0)) // 1-1
    fmt.Println(l.RangePluralRule(1, 0, 2, 0)) // 1-2
    fmt.Println(l.RangePluralRule(5, 0, 8, 0)) // 5-8
}

NOTES:

These rules were generated from the Unicode CLDR Project, if you encounter any issues I strongly encourage contributing to the CLDR project to get the locale information corrected and the next time these locales are regenerated the fix will come with.

I do however realize that time constraints are often important and so there are two options:

  1. Create your own locale, copy, paste and modify, and ensure it complies with the Translator interface.
  2. Add an exception in the locale generation code directly and once regenerated, fix will be in place.

Please to not make fixes inside the locale files, they WILL get overwritten when the locales are regenerated.
