function-file-tools

WAT

Small (hopefully) library to interact with files in Functional Programming Style.

AKA

All monad goodies of functional programing : ramda, data.task now combined with streams and node file programs.

How

npm install function-file-tools --save

Usage

Using es2015 style with object-stream-tools

const { readFileStream } = require('function-file-tools')
const ost = require('object-stream-tools')
 
const app = readFileStream(__dirname + '/README.md')
    .map(ost.map(e => e.split(/\n|\t/gi))
    .pipe(process.stdout))
 
app.fork(console.error, console.log)

Using ramda curried functions

const { readFileStream } = require('function-file-tools')
const ost = require('object-stream-tools')
const { split } = require('ramda')
 
const app = readFileStream(__dirname + '/README.md')
    .map(ost.map(split(/\n|\t/gi))
    .pipe(process.stdout))
 
app.fork(console.error, console.log)

Using node v.7 with --harmony

import { readFile, readFileStream, writeFile } from 'function-file-tools'
 
const app = readFile(__dirname + '/README.txt')
        .map(e => e.split(/\n|\t/gi))
        .chain(contents => writeFile(__dirname + '/.tmp.txt', contents))
 
// when you want to have side effect
app.fork(console.error, console.log)
