Spawn inline

Simple wrapper for spawn() function to make it work with await and line-command without need of array of attributes.

Usage sample:

const spawnInline = require('spawn-inline');
await spawnInline('git status', {cwd: 'repo-dir'}, (text, err) => console.log(text));
// or
await spawnInline('git status', 'repo-dir');

Function attributes

async function (command, options, callback)

• command - text command to spawn, e.g. 'git status' It can be an array. In that case the first element counts as command, and rest of the array - as parameters.
• (optional) options - original child_process.spawn options
  https://nodejs.org/api/child_process.html#child_process_child_process_exec_command_options_callback
  It can be a string - in this case parameter counts as "cwd" option (working directory)
• (optional) callback - function to call on stdout or stderr, if not specified - will call process.stdout.write/process.stderr.write

Callback

function (out, err)

• text - text output of called command
• err - boolean, indicates if error occured

Return value

Spawn-inline return an array filled with output lines.

Bugs

Be aware, that if command attribute is string, it is splitted by split(' '), so if you have spaces in your parameters values (e.g. commit message) you'll need to use array-style command.

await spawnInline('git commit -a -mMy new commit'); // - will result in error (caused by splitting "My new commit" string)
await spawnInline(['git', 'commit', '-a', '-mMy new commit']); // - will do the job traditional way
