Simple example how V8 can compile JavaScript source and run it
// Create a new context.
Local<Context> context = Context::New(isolate);
// Enter the context for compiling and running the hello world script.
Context::Scope context_scope(context);
// Create a string containing the JavaScript source code.
Local<String> source = String::NewFromUtf8(isolate, "'Hello' + ', World!'");
// Compile the source code.

rodw / directory-reader.coffee
Created October 10, 2013 02:52
Here's a little CoffeeScript routine that will recursively read the file-system, generating an object that represents a complete directory tree. This gist should be executable. You can run it with: `coffee directory-reader.coffee [FILENAME]` to dump a JSON representation of the object to stdout.
# Here's a little CoffeeScript routine that will recursively
# read the file-system, generating an object that represents
# a directory tree.
# The returned object will contain the following attributes:
#
# * `file` - the basename of the file.
# * `dir` - the directory containing the file.
# * `types` - an array containing zero or more of
# "File", "Directory", "SymbolicLink", "BlockDevice",
