gulp-html-i18n

Internationalize your HTML files with gulp!

Language Definition Files

gulp-html-i18n supports three formats for definition files: JavaScript, JSON, and YAML

JS

Given the following in a file named: lang/en-US/index.js

AMD

define({
  heading: "Welcome!",
  footer:  "Copyright 2015"
});

CommonJS

module.exports = {
  heading: "Welcome!",
  footer:  "Copyright 2015"
};

gulp-html-i18n will produce an object called index. You can then use ${{ index.heading }}$ to get a result of "Welcome!".

JSON

Given the following in a file named: lang/en-US/index.json

{
  "heading": "Welcome!",
  "footer":  "Copyright 2015"
}

gulp-html-i18n will produce an object called index. You can then use ${{ index.heading }}$ to get a result of "Welcome!".

YAML

Given the following in a file named: lang/en-US/index.yaml

heading: Welcome!
footer:  Copyright 2015

gulp-html-i18n will produce an object called index. You can then use ${{ index.heading }}$ to get a result of "Welcome!".

HTML Markup

To use either of the examples from above, replace the text in your HTML files with a formatted tag: ${{ library.tag.name }}$

${{ _lang_ }}$ , ${{ _langs_ }}$ , ${{ _default_lang_ }}$ , ${{ _filename_ }}$ , and ${{ _filepath_ }}$ are special markups, stand for current file language, all file languages, the defaultLang option, the output file name and the output file path relative to file.base.

Example: index.html

Initial:

<html>
  <body>
    <h1>${{ index.heading }}$</h1>
    <div>
      <!-- Website content -->
    </div>
    <div>${{ index.footer }}$</div>
  <body>
</html>

Output:

<html>
  <body>
    <h1>Welcome!</h1>
    <div>
      <!-- Website content -->
    </div>
    <div>Copyright 2015</div>
  <body>
</html>

Render Engine

gulp-html-i18n supports two renderEngines: regex, mustache

Regex

This is the default and is used either with the langRegExp (the most flexible) or delimiters (easier)

Mustache

Provides additional support for things like loops and conditionals. (for full mustache documentation) You must used delimiters for mustache, you cannot use langRegExp option

en/index.yaml [ Yaml is useful for multiline strings ]

home:
    paragraphs:
        - >
            First paragraph contents 
            put together in multiple lines
        - >
            Second paragraph
            also in multiple lines
        - Third Paragraph

gulpfile.js

i18n({
  langDir: './lang',
  renderEngine: 'mustache'
})

index.html

<h1>Welcome</h1>
${{# home.paragraphs }}$
    <p>${{ . }}$</p>
${{/ home.paragraphs }}$

Will produce : index-en.html

<h1>Welcome</h1>
<p>First paragraph contents put together in multiple lines</p>
<p>Second paragraph also in multiple lines</p>
<p>Third Paragraph</p>

Gulp Usage

The following task:

gulp.task('build:localize', function() {
  var dest  = './public';
  var index = './index.html';
 
  return gulp.src(index)
    .pipe(i18n({
      langDir: './lang',
      trace: true
    }))
    .pipe(gulp.dest(dest));
});

will compile index.html to public/index-{lang}.html for each language your define in ./lang.

Options

Option	Default	Type	Description
langDir (required)	undefined	String	Specifies the path to find definitions
filenameI18n	false	Boolean	If `true`, you can use ${{ xxx }}$ tag in your filename as in the file content, then the translated filename will contain the translated content instead of the language code.
createLangDirs	false	Boolean	If `true`, instead of translating `index.html` into `index-en.html`, etc, will translate to `en/index.html`, etc.
defaultLang	undefined	String	If defined and `createLangDirs` is `true`, translate `index.html` into `index.html` with the default language, etc.
renderEngine	regex	String	If given sets rendering to be done by regex or Mustache (for more functionality)
delimiters	['${{','}}$']	String[]	Can be used instead of `langRegExp`. Required to update mustache engine, langRegExp will not work with mustache
failOnMissing	false	Boolean	If `true`, any undefined tag found in an HTML file will throw an error. When `false`, missing tags are logged, but the process finishes.
fallback	undefined	String	If given, will use the provided language as a fallback: For any other language, if a given tag's value is not provided, it will use the fallback language value.
inline	undefined	String	If given, will use the provided language to create an output file of the same name as input. For example, passing `inline: 'en-US'` for `index.html` will result in `index.html` with English replacements.
langRegExp	/${{ ?([\w-.]+) ?}}$/g	RegExp	the regular expression used for matching the language tags.
escapeQuotes	false	Boolean	If `true`, will replace `"` and `'` with `\\"` and `\\'`.
trace	false	Boolean	If `true`, will place comments in output HTML to show where the translated strings came from
extendDefination	undefined	Function	return an object to extend the language defination
