Lao interpreter

This is an interpreter implemented in Go for a simple BASIC-like language called Lao. This was created as part of a programming languages course.

Parts

This is implemented in the following simple parts:

  1. Tokenizer - turns stream of characters into recognizable tokens
  2. Parser - Parser turns the tokens into an AST
  3. Interpreter - Takes in an AST and runs the program.

How to use

In order to install and run a sample program:

go get github.com/vectorhacker/lao
go install github.com/vectorhacker/lao

lao <path_to_program>

Next steps

The Lao language is incomplete as a language. It is missing simple jumps and loops. It also lacks a repl.
