goto-lang

goto-lang is a simple programming language with only GOTO statements for control flow and a small set of instructions.

Getting started

git clone https://github.com/gaganchandan/goto-lang
cd goto-lang/src
dune build --release
dune exec --release goto <program>

Language features

goto-lang only allows operations in two data types, integers and string. Variables can be defined of either of these two types. 24 different instructions are avaailabe. The general syntax for instructions is as follows:

INSTR op1 op2 .. opn

Control flow is performed using the goto instruction. Conditional goto instruction make use of something known as the cmpflag which is partly inspired by flags and conditional jumps in x86 assembly. Comments are supported as well, and begin with -- as seen in Lua.

The examples/ directory contains trivial programs showcasing goto-lang's capabilities. If you just want a "Hello, World!" program, then here you go!

_entry:
  PRINT "Hello, World!\n"

A slightly more complex variant:

_entry:
  PRINT "What is your name?\n"
  GETSTR name 
  VAR msg "Hello, "
  ADDI msg name
  ADDI msg "!\n"
  PRINT msg
