Implementation of Unlambda, an esoteric programming language.

## Description

The U6a project provides a bytecode compiler and a runtime system for the [Unlambda](http://www.madore.org/~david/programs/unlambda/) programming language.

Ideas behind this implementation can be found [here](https://git.cismon.net/esolangs/u6a/wiki/Developer%27s-Notes-on-Implementing-Unlambda).

U6a is free software. You can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version.

## Getting Started

To install U6a from source, see [INSTALL](INSTALL).

Usage (See [**u6ac**(1)](man/u6ac.1) and [**u6a**(1)](man/u6a.1) man pages for details):

```bash
# Compile an Unlambda source file into bytecode.
u6ac -o foo.unl.bc foo.unl
# Execute the bytecode file.
u6a foo.unl.bc
```

## Future Plans

* Interactive debugger: `u6adb`
* More compile-time optimizations
* More test cases
* LLVM backend for `u6ac`
