Eva Programming Langauge

Dynamic programming langauge.

Simple syntax, functional heart, OOP support.

Eva Expressions:

(<type> <op1> <op2> ... <opN>)

Example:

(+ 5 10)
(set x 15)

(if (> x 10)
	(print "ok")
	(print "error")
)

(def foo (bar)
	(+ bar 10)
)

(lambda (x) (* x x) 10)

Design Goals

• Simple syntax: S-Expression
• Everything is an expression
• No explicit return, last evalulated expression is the result
• First class functions
• Static scope: all functions are closures
• Lambda functions
• Funcitonal programming
• Imperative programming
• Namespaces and modules
• OOP: Class or prototype based.
