gulp-combine-languagefiles

Gulp plugin to combine several (nested) JSON language files Create easily editable CSV so non-programmers can help with translations

This plugin was originally made to be used with gulp-bobrsass-boilerplate / angularjs, but it should work with other projects too using JSON key-value -pair translations. It expects translations to be named as en.json, en-EN.json or similar. Your project tree might look for example like

src/
	app/
		module1/
			languages/
				en.json
				fi.json
		module2/
			languages/
				en.json
				fi.json

Usage

Install gulp-combine-languagefiles as a development dependency:

npm install --save-dev gulp-combine-languagefiles

Add it to your gulpfile.js:

var combine_languagefiles = require("gulp-combine-languagefiles");
 
gulp.src("src/app/**/languages/*.json")
    .pipe(combine_languagefiles("translations.json"))
    .pipe(gulp.dest(""));

You can use gulp-convert to convert result to CSV. Use includeHeader parameter to prepend header as first row.

var concat_json = require("gulp-concat-languagefiles");
var convert = require("gulp-convert");
 
gulp.src("src/app/**/languages/*.json")
    .pipe(combine_languagefiles("translations.json", { includeHeader: true }))
    .pipe(convert({from: 'json', to: 'csv'}))
    .pipe(gulp.dest("")); // File will be saved as translations.csv to project root

See /example for a script to parse generated CSV back to original JSON-files, it even supports downloading CSV from Google Drive!
