describe(obj)

Type describe(obj), where obj is the name of some object, and the interpreter will list the methods and other members of that object.

load(assemblypath)

load(assemblypath) is useful for adding a reference to a dll for later code.

To load an assembly by name instead of file path, use the extended Import syntax, i.e. "import System.Windows.Forms from System.Windows.Forms".

interpreter

You can reference the interpreter object itself as "interpreter". For example, you can turn default Duck Typing off by typing "interpreter.Ducky = false"

globals()

Prints out all the objects that the interpreter has stored in your session.

last value

The symbol "_" (underscore) refers to the last value returned by the interpreter. For example:

dir(obj)

Similar to describe, dir spits out an array of all the type members contained by an object.

Support for multi-line code blocks

Just type the line beginning the code block (like "def mymethod():" or "class MyClass:", then return and you'll be able to indent the following lines just like in a regular boo script. Hit return twice to end the indented block.

line history

Hit the up arrow key to see previous lines you have typed in. Edit the line and hit Enter to resubmit it.

code completion

The sharpdevelop version of booish hooks into SharpDevelop's code completion engine.

Duck typing

Implicit Duck Typing is on by default. Useful for quicker coding, i.e., this code will run fine in the interpreter: (no need to declare "p as string")

>>>def doit(p):
...   print p.ToUpper()
...
>>>doit("a string")
A STRING
