node-autodetect-utf8-cp1251-cp866 v0.1.0

node-autodetect-utf8-cp1251-cp866

Autodetect Buffer encoding (cyr)

Install

$ npm install node-autodetect-utf8-cp1251-cp866

Usage

Example #1 - simple synchronous case for Node.JS

const autoenc = require('node-autodetect-utf8-cp1251-cp866');
const fs = require('fs');

let buff = fs.readFileSync('./any.txt'); // Note: only one parameter
console.log(autoenc.detectEncoding(buff).encoding);
console.log(autoenc.detectEncoding(buff).text.substr(0,32)+'...');

Example #2 - asynchronous file reading, Node.JS

Note: this library itself is synchronous

const autoenc = require('node-autodetect-utf8-cp1251-cp866');
const fs = require('fs');

fs.readFile('./any.txt', (err, buff) => {
    if (err) {
        throw err;
    }
    console.log(autoenc.detectEncoding(buff).encoding);
});

Example #3 - asynchronous file reading with Promises, Node.JS

const autoenc = require('node-autodetect-utf8-cp1251-cp866');
const fs = require('fs');

let ps = new Promise((resolve, reject) => {
	fs.readFile('any.txt', (err, buff) => {
		if (err) {
			reject(err);
		}
		resolve(autoenc.detectEncoding(buff).encoding);
	});
});

ps.then(encoding => console.log(encoding));

Example #4 - autodetect file which is loaded with input (for browser and browserify)

// This example for browser and browserify
const iconv = require('iconv-lite');
const autoenc = require('node-autodetect-utf8-cp1251-cp866');

function codeLoad() {

	var readers = [];
	// Closure to capture the file information.
	var f = document.getElementById('file-load').files[0];
	var reader = new FileReader();
	reader.onload = (function(theFile) {
		return function(e) {
			try {
				encoding = autoenc.detectEncoding(e.target.result).encoding;
				var text = iconv.decode(new Buffer(e.target.result), encoding);
				return {
					fileText: text,
					fileName: theFile.name,
					fileEnc: encoding
				};
			} catch (err) {
				alert('Could not read ' + theFile.name);
				console.log(err);
			}
		};
	})(f);
	reader.readAsArrayBuffer(f);
};
