For the sake of discussion, let's pretend it's a testing harness you've named `testify`. - -Everything is going splendidly until one day you decide to test some code that relies on a feature behind a v8 flag in node (`--harmony`, for example). Without much thought, you run `testify --harmony spec tests.js`. - -It doesn't work. After digging around for a bit, you realize this produces a [`process.argv`](http://nodejs.org/docs/latest/api/process.html#process_process_argv) of: - -`['node', '/usr/local/bin/test', '--harmony', 'spec', 'tests.js']` - -Crap. The `--harmony` flag is in the wrong place! It should be applied to the **node** command, not our binary. What we actually wanted was this: - -`['node', '--harmony', '/usr/local/bin/test', 'spec', 'tests.js']` - -Flagged-respawn fixes this problem and handles all the edge cases respawning creates, such as: -- Providing a method to determine if a respawn is needed. -- Piping stderr/stdout from the child into the parent. -- Making the parent process exit with the same code as the child. -- If the child is killed, making the parent exit with the same signal. - -To see it in action, clone this repository and run `npm install` / `npm run respawn` / `npm run nospawn`. - -## Sample Usage - -```js -#!/usr/bin/env node - -const flaggedRespawn = require('flagged-respawn'); - -// get a list of all possible v8 flags for the running version of node -const v8flags = require('v8flags').fetch(); - -flaggedRespawn(v8flags, process.argv, function (ready, child) { - if (ready) { - console.log('Running!'); - // your cli code here - } else { - console.log('Special flags found, respawning.'); - } - if (process.pid !== child.pid) { - console.log('Respawned to PID:', child.pid); - } -}); - -``` - - -## API - -### <u>flaggedRespawn(flags, argv, [ forcedFlags, ] callback) : Void</u> - -Respawns the script itself when *argv* has special flag contained in *flags* and/or *forcedFlags* is not empty.
