Check if Node’s built-in source map stack trace transformations are enabled.
nodeSourceMapsSupportEnabled = process? and (
process.execArgv.includes('--enable-source-maps') or

patchStackTrace()
Load and run a CoffeeScript file for Node, stripping any BOM
s.
loadFile = (module, filename) ->
options = module.options or getRootModule(module).options or {}
Currently CoffeeScript.compile
caches all source maps if present. They
are available in getSourceMap
retrieved by filename
.
if cacheSourceMaps or nodeSourceMapsSupportEnabled
options.inlineMap = true
js = CoffeeScript._compileFile filename, options
module._compile js, filename
If the installed version of Node supports require.extensions
, register
CoffeeScript as an extension.
if require.extensions
for ext in CoffeeScript.FILE_EXTENSIONS
require.extensions[ext] = loadFile
Patch Node’s module loader to be able to handle multi-dot extensions. This is a horrible thing that should not be required.
Module = require 'module'
findExtension = (filename) ->
extensions = path.basename(filename).split '.'
Remove the initial dot from dotfiles.
extensions.shift() if extensions[0] is ''
Start with the longest possible extension and work our way shortwards.
while extensions.shift()
curExtension = '.' + extensions.join '.'
return curExtension if Module._extensions[curExtension]
'.js'
Module::load = (filename) ->
@filename = filename
@paths = Module._nodeModulePaths path.dirname filename
extension = findExtension filename
Module._extensions[extension](this, filename)
@loaded = true
If we’re on Node, patch child_process.fork
so that Coffee scripts are able
to fork both CoffeeScript files, and JavaScript files, directly.
if child_process
{fork} = child_process
binary = require.resolve '../../bin/coffee'
child_process.fork = (path, args, options) ->
if helpers.isCoffee path
unless Array.isArray args
options = args or {}
args = []
args = [path].concat args
path = binary
fork path, args, options
Utility function to find the options
object attached to the topmost module.
getRootModule = (module) ->
if module.parent then getRootModule module.parent else module
