node-pager

A super simple module that outputs text into less.

Usage

Install

$ npm install --save node-pager

Require

const fs = require('fs')
const pager = require('node-pager')

// read file contents and print to a pager
fs.readFile('somefile.txt', (err, data) => {
  pager(data.toString('utf8')).then(() => {
    console.log('pager exited')
  })
})

You can specify options to be passed to less (only if your platform is not windows).

pager('my string', '-F'); // less -F
pager('my string'); // by default less -R (allows colors)

Careful -- less options are passed directly to a system call. Do not pass user input or other potentially malicious code. Only the first argument is properly sanitized.
