LeafLang Compiler

LeafLang compiler is currently under development.Anything may change .

Output Structure

Note:This is a standard and the code is yet to be completed.

For Example the source code:

Code:

function sth:(args){
    println("hi");
};
var somevar=1024;
class AClass{
    function _init:(x,y){
        x=1;
        y=2;
    };
    function dosth{
        println("yayay");
    };
};

The compiler will translate the source file into like this:

root
\_ .conpl
\_ sth.func
\_ somevar.var
\_ AClass
\___ _init.func
\___ dosth.func

And Then,It zips the root file to make a leaflang executable file.(Yeah it is just a zip archive)

ByteCode

Every code starts with an Operation Code and then the optional arguments.

First,each type of id’s length:

Constant Pool

Operation Code:0x01

Follows by:

• Arguments count:expressed as a num
• {Arguments count} constant pool elements

Constant Pool Element

Structure:

Tag+Value

Num

Tag:\x00

Value:type num

String

Tag:\x01

Value:

• type num count of string
• utf-8 string

OpCodes

See docs in OpCodes.py.

Example

var a=10;
var b=11;
a=b;
