Things in Boo but Not Python
- quickly compile boo script to standalone cross-platform exe
- easy super(), and constructor automatically calls super() for you. If you don't have a constructor, one is created for you.
- set class properties via the constructor (constructor doesn't have to handle them explicitly):
Code Block x = MyClass(Property1:"value1", Property2:"value2") - Anonymous Closures - including multi-line closures:
Code Block b = Button(Text:"Press Me") b.Click += def(): MessageBox.Show("you clicked me") - Events, Callable Types
- unless statement: print "good job" unless score < 75
- built-in support for Regular Expressions
- timespan literals (example: t = 10ms)
- extensible compiler pipeline
- custom Syntactic Macros
since boo is statically typed, you get:
- static typing: "x as int" but you can just say "x" (x is an object)
- Interfaces, Enums
- private,public,protected,final,etc. variables & methods
- speed increases - without having to convert your code to a different language like C
- easier interoperability since boo uses standard CLI types (e.g. string is System.String, int is a System.Int32...)
- convert C# and VB.NET to boo code (part of the Boo AddIn For SharpDevelop)
other C#/.NET features you get:
- "lock" (like java's synchronized). See the lock* examples under tests/testcases/semantics/.
- property getters and setters
- using: (automatically disposes of object when you are done using it)
Code Block //in this example you can also use the simpler // "for line in StreamReader("filename"):" using f = System.IO.StreamReader('using0.boo'): while line = f.ReadLine(): print line - parameter checking
Code Block def foo([required(value > 3)] value as int): pass - [attributes] for functions, fields, classes...
- asynchronous execution, see Asynchronous Design Pattern.
- XML Serialization
