What is YetiScript?

YetiScript compiles yeti code to JavaScript.

Yeti is an ML-style functional programming language, with static type-inference with tries to be clean and minimal expressive and to interface well with JavaScript code.

YetiScript tries to be as close to yeti as it can, however there are some differences.

Status

YetiScript is in early development and still very buggy, however it compiles nearly all of yeti-code.

See the Wiki in the wiki

Get Started

Java JDK7 is required an java must be on the path. YetiScript itself is distributed as a npm-module. To install it execute the follwing commands

//test jave version
>java -version 
java version "1.7.0....."

//install yetiscript
>npm install yetiscript -g
....

//use yjs to run the yetiscript compiler
>yjs
help msg ....

Alternatively (and to use the lates version) you can git clone it and build it with ant

> git clone git://github.com/chrisichris/yetiscript.git
> cd yetiscript
> ant

The resulting yjs.jar contains everything needed and can be use like the npm yjs command:

Basic Usage:

Evaluate an expression with node:

$yjs -e "1 + 1" | node

evaluate an expression with rhino (build into JDK7):

$yjs -r -e "1 + 1"

run an example using node:

yjs examples/fact.yjs | node 

run an example using the build in rhino:

yjs -r examples/fact.yjs 

compile an example to build directory

yjs -d build examples/fact.yjs

print help

yjs yjs.jar -h
