Use snockets to package javascript files for debug output (with //@ sourceURL)

snockets-debug.coffee

#entry point for js/coffee dependency tree
rootfile = 'root.js'

#get the file names and content
files = snockets.getCompiledChain rootfile, { async: false }

#package each file in eval with trailing //@ sourceURL
scripts = []
for file in files
  script = file.js.replace(/\\/g, '\\\\').replace(/\n/g, '\\n').replace(/'/g, '\\\'')
  name = path.relative(path.dirname(@filename), file.filename)
  scripts.push "// #{name}\neval('#{script}\\n//@ sourceURL=#{name}')\n"

# join scripts into single package ready to be sent to the client
jsPackage = scripts.join('\n')
