OOLANG(Object Oriented LANGuage), simple stack based esoteric programming language, but with object oriented syntax.

Examples

Hello, World!

Hello, World!.println;

99 bottles of beer

i.99.set;
t.0.set;
i.2int;
t.2int;

start.label;
i!=t.7.17.if;

i.dec;
i.get;
%sbottles of beer on the wall,%s.print;
i.get;
%sbottles of beer%d%n.print;
Take one down and pass it around,%s.print;
i.get;
%sbottles of beer on the wall%n.print;
start.goto;

No more bottles of beer on the wall, no more bottles of beer%d%n.print;
Go to the store and buy some more, 99 bottles of beer on the wall%d.print;

Counts to ten

i.0.set;
t.10.set;

Powering number

Using JavaScript.

Deadfish interpreter

In this interpreter added instruction "h", to end execution.

x.0.set;
a.label;
a.Input code:..in;

x>256.31.5.ifa;

var1.var2.sub

var -= var2

var1.var2.mul

var *= var2

var1.var2.div

var /= var2

var.str.delim.strsplit

splits value of var by delim in var<

var.var1.var2.strcat

Conditional

conditional.lineif.lineelse.if

compare variables value(e.x. a==b) and gotos to lineif if true, and to lineelse if false

conditional.lineif.lineelse.ifa

compare variable and value(e.x. a==5) and gotos to lineif if true, and to lineelse if false

conditional.labelif.labelelse.ifg

compare variables value(e.x. a==b) and gotos to labelif if true, and to labellse if false

Special

text.halt

end program

none.gl

printing current line to console(for debuging)

js.evljs

evaling javascript and printing result

var.js.evjs

evaling javascript and puting result into var

Comment

comment.rem

one line comment

It's turing complete?

Yes, because we can easily use javascript api. Very simple example:

a.5.set;
b.5.set;
Using javascript!.rem;
out.stack["a"]+stack["b"].evjs;
out.get;
