# Extended: Like {BufferedProcess}, but accepts a Node script as the command

# to run.

# This is necessary on Windows since it doesn't support shebang `#!` lines.

# ## Examples

# ```coffee

# {BufferedNodeProcess} = require 'atom'

# ```

module.exports =

class BufferedNodeProcess extends BufferedProcess

# Public: Runs the given Node script by spawning a new child process.

# * `options` An {Object} with the following keys:

# * `command` The {String} path to the JavaScript script to execute.

# * `args` The {Array} of arguments to pass to the script (optional).

# * `options` The options {Object} to pass to Node's `ChildProcess.spawn`

# method (optional).

# * `stdout` The callback {Function} that receives a single argument which

# contains the standard output from the command. The callback is

# called as data is received but it's buffered to ensure only

# complete lines are passed until the source stream closes. After

# the source stream has closed all remaining data is sent in a

# final call (optional).

# * `stderr` The callback {Function} that receives a single argument which

# contains the standard error output from the command. The

# callback is called as data is received but it's buffered to

# ensure only complete lines are passed until the source stream

# closes. After the source stream has closed all remaining data

# is sent in a final call (optional).

# * `exit` The callback {Function} which receives a single argument

# containing the exit status (optional).
