Gulp Translator

Almost like string replace but using locales Now you can use both .json and .yml files.

Usage

First, install gulp-translator as a development dependency:

npm install --save-dev gulp-translator

Then, add it to your gulpfile.js:

var translate = require('gulp-translator');

gulp.task('translate', function() {
  var translations = ['pl', 'en'];

  translations.forEach(function(translation){
    gulp.src('app/views/**/*.html')
      .pipe(translate(options))
      .pipe(gulp.dest('dist/views/' + translation));
  });
});

or better, handle errors:

gulp.task('translate', function() {
  var translations = ['pl', 'en'];

  translations.forEach(function(translation){
    gulp.src('app/views/**/*.html')
      .pipe(
        translate(options)
        .on('error', function(){
          console.error(arguments);
        })
      )
      .pipe(gulp.dest('dist/views/' + translation));
  });
});

Options

options in translate function is:

• String Path to locale file.
• Object
  • .localePath String. Optional. Path to locale file. Or you can use .lang, .localeDirectory.
  • .lang String. Optional. Target language.
  • .localeDirectory String. Optional. Directory with locale files. If no .localePath specified, try construct it from .localeDirectory + .lang.
  • .localeExt String. Optional. If you specify path to file will transform newLocalePath = oldLocalePath + .localExt.
  • .pattern RegExp. Optional. Pattern to find strings to replace. You can specify your own pattern. To transform strings without translate. Default: /\{{2}([\w\.\s\"\']+\s?\|\s?translate[\w\s\|]*)\}{2}/g
  • .patternSplitter String. Some to split parts of transform. Default: '|'.
  • .transform Object. Every field is you transform function. First argument is an content to transform it. Second is an dictionary, that you specified. Function should return transformed string or Error object with some message.

Usage

I'm using angular-like syntax. Expressions in {{}} with | translate filter will be translated.

Following examples assume that "title" in locales equals "new TITLE"

Example:

{{ title | translate }} will be change to "new TITLE"

If you'd like to use filters(look at the bottom to check available filters) just pass them after like that:

{{ title | translate | lowercase }} will be change to "new title"

{{ title | translate | uppercase }} will be change to "NEW TITLE"

If you're still not sure, please look at tests.

API

gulp-translator is called with a string

translate(string)

string

Type: String

The string is a path to a nameOfTheFile.yml with your locales. Please look at test/locales for examples.

Available filters:

• lowercase
• uppercase
• capitalize to capitalize only first word.
• capitalizeEvery to capitalize every word.
• reverse

User filters:

You also can specify your own filters. Just add them to .transform parameter of options. First argument is an content to transform it. Second is an dictionary, that you specified. Function should return transformed string or Error object with some message.

TODO:

• refactor tests
• work on matchers (sigh...)
