Goodbye Neko VM, Hello Lua - 10 May 2010

What It Is

Brat is a little toy language that just doesn’t care. It is dynamically typed, with objects, first-class functions, and simple syntax.

Where It Is

Brat may be obtained using any of the following methods:

• Clone with Git: git clone git://github.com/presidentbeef/brat
• Download in zip or tar format
• Browse around the source

How It Looks

Here is the Brat ‘hello world’ program:

p "Hello, world!"

Here is a slightly more interesting, object-oriented ‘hello world’:

world = new
world.hello! = { p "Hello, world!" }
world.hello!

Here’s one to say hello to you:

world = new
world.greet = { name | p "Hello, ", name, "!"}
print "What is your name? "
your_name = g
world.greet your_name

Why You Should Use Brat

An arbitrary number of reasons to use Brat:

1. Plenty of sharp knives
2. No rigid class hierarchies
3. No classes at all
4. No pointless restrictions, only pointful ones
5. No keywords to learn
6. No one is going to tell you ‘no’
7. No one else is

Who Should Use Brat

You should use Brat if:

• No one is the boss of you
• You just don’t care
• You do what you wanna
• You don’t have a thing to prove

Who Probably Shouldn’t Use Brat

• You need to know what ‘type’ something is
