tabs-to-spaces-stream

A little library that converts tabs in streaming data to spaces.

Installation

npm install --save tabs-to-spaces-stream

Usage

const fs = require('fs')
const {convertStream} = require('tabs-to-spaces-stream')

const myStream = fs.createReadStream('hello.txt') //contents: hello   world

myStream
    .pipe(convertStream(4))
    .pipe(process.stdout)

// hello    world

API

convertStream(numberOfSpaces)

 const {convertStream} = require('tabs-to-spaces-stream')
/**
 * Returns a transform stream converting tabs to spaces. 
 * Buffer streams will be converted to strings by default.
 *
 * @param {number} [numberOfSpaces=2] The number of spaces 
 * to replace each tab with.
 * @throws {RangeError}
 * @returns {stream}
 */

 src
    .pipe(convertStream())
    .pipe(dest)

convert(str, numberOfSpaces)

Alternatively you can use the base function that converts tabs to spaces in a string.

 const {convert} = require('tabs-to-spaces-stream')
/**
* Returns a string converting tabs to spaces
*
* @param {string} str
* @param {number} [numberOfSpaces=2] The number of spaces 
* to replace each tab with. Default is 2.
* @returns {string}
*/

convert('Hello   world', 6) // 'Hello      world'
