gulp-csv-angular-translate (gCat)

Gulp plugin for generating multiple language JSON files out of one CSV File.

What's it for?

When using angular-translate with asynch loading and splitted language files for minimizing the network traffic, writing the different JSON-Files can be confusing.

This Plugin provides a simple way of translating the different languages in only one .csv-File and generating the needed .json-Files.

The .csv-File:

Key | de_DE | en_US | en_UK ------------ | ------------- | ------------- | ------------- HELLO | Hallo | Hello | Hello WORLD | Welt | World | World

Results in the three .json-Files: de_DE.json, en_US.json, en_UK.json

de_DE.json: {"HELLO":"Hallo","WORLD":"Welt"}

en_US.json: {"HELLO":"Hello","WORLD":"World"}

en_UK.json: {"HELLO":"Hello","WORLD":"World"}

How to use the plugin

Install the plugin:

npm install --save gulp-csv-angular-translate

Write the gulp task:

var gCat = require('gulp-csv-angular-translate');
gulp.task('lang', function() {
     gulp.src('lang.csv') //language source .csv
         .pipe(gCat()) //run the plugin
         .pipe(gulp.dest('build')); //put out the .json-files in a specified folder
});

Configurations

Configure the csv-parser options

The options for the csv parser can be configured under csvParserOptions. Find the possible configurations here.

Example:

gulp.task('lang', function() {
    gulp.src('lang.csv')
        .pipe(gCat({
            csvParseOptions: {
                delimiter: ';',
                trim: true
            }
        }))
        .pipe(gulp.dest('build'));
});

Skip empty translations

The option skipEmptyTranslations always empty translations to be skipped. This means that empty columns don't result in an empty translation string.

Example:

gulp.task('lang', function() {
    gulp.src('lang.csv')
        .pipe(gCat({
            skipEmptyTranslations: true
        }))
        .pipe(gulp.dest('build'));
});
