cliExt

A package for cli input handling. This package simplifies the hassle to allow file input, piped input. It even supports editor inputs when no input is given.

Installation

Via npm

npm install cli-ext

Usage

import * as cliExt from 'cli-ext'

// get stdin input or if none is given open an editor
cliExt.input()
.then((contents) => console.log('stdin or editor input: ', contents))

// if the second process argument is a file it opens that file
// otherwise check stdin
// default to an editor if none of the above is set
cliExt.input(process.argv[2])
.then((contents) => console.log(contents))

// opens an editor to edit the file `config.json`
cliExt.edit('./config.json')
.then((json) => ...)

// opens an editor to edit the given text
cliExt.editContent('text to display in the editor')
.then((text) => ...)

// use a function to verify the contents of the input.
// Here we want to ensure that the content is at least 100 characters long
cliExt.input(process.argv[2], {verify: (content) => content.length > 100})
.then((text) => ...)
