Locales is a set of locales generated from the [Unicode CLDR Project](http://cldr.unicode.org/) which can be used independently or within
|
|
an i18n package; these were built for use with, but not exclusive to, [Universal Translator](https://github.com/go-playground/universal-translator).
|
|
|
|
Features
|
|
--------
|
|
- [x] Rules generated from the latest [CLDR](http://cldr.unicode.org/index/downloads) data, v36.0.1
|
|
- [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](https://github.com/go-playground/locales/issues/1) for details.
|
|
|
|
Installation
|
|
-----------
|
|
|
|
Use go get
|
|
|
|
```shell
|
|
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
|
|
-------
|
|
```go
|
|
package main

|
"github.com/go-playground/locales/currency"
|
|
"github.com/go-playground/locales/en_CA"
|
|
)
|
|
|
|
func main() {

NOTES:
|
|
-------
|
|
These rules were generated from the [Unicode CLDR Project](http://cldr.unicode.org/), 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.
