|
|
|
|
The bare-bones internationalization library used by yargs.
|
|
|
|
Inspired by [i18n](https://www.npmjs.com/package/i18n).
|
|
|
|
## Examples
|
|
|
|
_simple string translation:_
|
|
|
|
```js
|
|
var __ = require('y18n').__
|
|
|
|
console.log(__('my awesome string %s', 'foo'))
|
|
```
|
|
|
|
output:
|
|
|
|
`my awesome string foo`
|
|
|
|
_using tagged template literals_
|
|
|
|
```js
|
|
var __ = require('y18n').__
|
|
var str = 'foo'
|
|
|
|
console.log(__`my awesome string ${str}`)
|
|
```
|
|
|
|
output:
|
|
|
|
`my awesome string foo`
|
|
|
|
_pluralization support:_
|
|
|
|
```js
|
|
var __n = require('y18n').__n
|
|
|
|
console.log(__n('one fish %s', '%d fishes %s', 2, 'foo'))
|
|
```
|
|
|
|
output:
|
|
|
|
`2 fishes foo`
|
|
|
|
## JSON Language Files
|
|
|
|
The JSON language files should be stored in a `./locales` folder.
|
|
File names correspond to locales, e.g., `en.json`, `pirate.json`.
|
|
|
|
When strings are observed for the first time they will be
|
|
added to the JSON file corresponding to the current locale.
|
|
|
|
## Methods
|
|
|
|
### require('y18n')(config)
|
|
|
|
Create an instance of y18n with the config provided, options include:
|
|
|
|
* `directory`: the locale directory, default `./locales`.
|
|
* `updateFiles`: should newly observed strings be updated in file, default `true`.
|
|
* `locale`: what locale should be used.
|
|
* `fallbackToLanguage`: should fallback to a language-only file (e.g. `en.json`)
|
|
be allowed if a file matching the locale does not exist (e.g. `en_US.json`),
|
|
default `true`.
|
|
|
|
### y18n.\_\_(str, arg, arg, arg)
|
|
|
|
Print a localized string, `%s` will be replaced with `arg`s.
|
|
|
|
This function can also be used as a tag for a template literal. You can use it
|
|
like this: <code>__`hello ${'world'}`</code>. This will be equivalent to
|
|
`__('hello %s', 'world')`.
|
|
|
|
### y18n.\_\_n(singularString, pluralString, count, arg, arg, arg)
|
|
|
|
Print a localized string with appropriate pluralization. If `%d` is provided
|
|
in the string, the `count` will replace this placeholder.
|
|
|
|
### y18n.setLocale(str)
|
|
|
|
Set the current locale being used.
|
|
|
|
### y18n.getLocale()
|
|
|
|
What locale is currently being used?
|
|
|
|
### y18n.updateLocale(obj)
|
|
|
|
Update the current locale with the key value pairs in `obj`.
