robo-painter is a simple program to procedurally generate random, grayscale images with two parts:

1. a picture-generation language (written in C)
2. a library for genetic programming in Lua.

Currently, only part 1 is complete.

The bulk of the code is contained in liblang.c which holds the procedures and data structures related to the language. Perhaps the most intersting feature of the language is that any string of LANG_WORDs (as defined in liblang.h) is a valid expression in the language, which allows them to be easily manipulated, generated, or otherwise mutated.

BUILDING

The following has been tested on Ubuntu 18.04 LTS:

1. sudo apt-get install git make gcc lua5.1 liblua5.1-dev
2. git submodule init && git submodule update
3. sudo apt-get install libgd-dev to get the dependencies, followed by sudo apt-get remove libgd-dev (unfortunately, installing libgd-dev doesn't appear sufficient to get lua-gd to work on its own)
4. Download the latest release of libgd from https://libgd.github.io/pages/downloads.html and install it with the usual ./configure && make && sudo make install dance
5. Finally, cd lib/lua-gd && make

To run, type make run for a fixed demo or lua5.1 robo.lua for a random seed, and check images/.
