node.js - How can I access command options in separate files? -

-

i'm using commander specify commands , options global node module in index.js file of project (like shown in example).

i know can check if command used using following code:

if (program.peppers) {   console.log('-peppers used') }

but how can check properties in other files? i've tried exporting program , requiring in other files, doesn't seem work.

let's want check if option used in different file in 1 in i've defined them. how should that?

you pass parsed program files/functions need parsed arguments or can export parsed arguments program instance

file index.js

var program = require('./program');  if (program.peppers) {   console.log('-peppers used') }

file program.js

var program = require('commander');  program   .version('0.0.1')   .option('-p, --peppers', 'add peppers')   .option('-p, --pineapple', 'add pineapple')   .option('-b, --bbq-sauce', 'add bbq sauce')   .option('-c, --cheese [type]', 'add specified type of cheese [marble]', 'marble')   .parse(process.argv);  module.exports = program;

invoking index.js command line:

> node index.js -p

yields output

-peppers used
