I/O Lib

Text and binary file essential I/O

by Read Write Tools Aug 21, 2015
Abstract
The iolib JavaScript library has functions for handling line-by-line text I/O, block-oriented binary I/O, and filesystem operations.

Motivation

Reading and writing text files using line-oriented functions is a common need. Handling block transfers of binary data is necessary for packed data formats.

Performing basic filesystem operations complements these two.

Features

The TextReader class has a UTF-8 aware getline method for parsing a text file one line at a time.

The TextWriter class has putline and puts methods to serialize to a text file.

The lower level BinaryReader reads a block of 8192 bytes, advancing the buffer pointer with each read.

The BinaryWriter class has methods for writing Strings, Buffers, 4-bytes, 2-bytes, and 1-byte .

The Pfile class has methods for checking if a file exists; if it's a directory or a symlink; if it's readable, writable, executable; and for assembling and accessing parts of a file's path, basename, and extension.

Installation

The iolib library may be installed directly from github or via NPM.

[user@host]# npm install iolib

Sample usage of the libary in a node.js project:

import{TextReader}from'iolib';import{TextWriter}from'iolib';import{BinaryReader}from'iolib';import{BinaryWriter}from'iolib';import{Pfile}from'iolib';

I/O Lib
Text and binary file essential I/O
 by Read Write Tools Aug 21, 2015

Abstract
The iolib JavaScript library has functions for handling line-by-line text I/O, block-oriented binary I/O, and filesystem operations.
Motivation
Reading and writing text files using line-oriented functions is a common need.
Handling block transfers of binary data is necessary for packed data formats.
Performing basic filesystem operations complements these two.
Features
The TextReader class has a UTF-8 aware getline method for parsing a text file
one line at a time.
The TextWriter class has putline and puts methods to serialize to a text file.
The lower level BinaryReader reads a block of 8192 bytes, advancing the buffer
pointer with each read.
The BinaryWriter class has methods for writing Strings, Buffers, 4-bytes,
2-bytes, and 1-byte .
The Pfile class has methods for checking if a file exists; if it's a directory
or a symlink; if it's readable, writable, executable; and for assembling and
accessing parts of a file's path, basename, and extension.
Installation
The iolib library may be installed directly from github or via
NPM.
[user@host]# npm install iolib
Sample usage of the libary in a node.js project:
import{TextReader}from'iolib';import{TextWriter}from'iolib';import{BinaryReader}from'iolib';import{BinaryWriter}from'iolib';import{Pfile}from'iolib';
