This is the code accompanying my blog post: Generating Mazes with Inductive Graphs.

libcairo is a C++ library, their site and instructions on how to install by OS can be found here: http://cairographics.org/download/
On Ubuntu, you can install it with apt-get:
sudo apt-get install libcairo2-dev
Get the project:
git clone https://github.com/TikhonJelvis/inductive-mazes.git
cd inductive-mazes
If your cabal bin directory is not in your PATH, add it:
export PATH=$HOME/.cabal/bin:$PATH – or wherever your cabal directory is
The project should probably be built inside of a sandbox.
cabal sandbox init
cabal install gtk2hs-buildtools
cabal install inductive-mazes.cabal
Building under Stack is quite simple and obviates the need for building within a cabal sandbox.
Get the project:
git clone https://github.com/TikhonJelvis/inductive-mazes.git
cd inductive-mazes
From within the project directory, run:
stack init
Stack will then install the packages locally for the project.
Run the following inside the inductive-mazes directory:
cabal repl
If using stack, run:
stack ghci
Once in the ghci instance, run:
*Draw> genPng defaults "my-maze.png" 40 40
^D – exiting cabal repl
After having returned to the terminal, view the new maze file with your
favourite .png views:
eog my-maze.png -- or whatever your png viewer is
