Raku Graph::RandomMaze

Raku package for random maze making using graphs.

The package provides the function random-maze the implementation of which is explained in [AA1].

Remark: Since the package "Graph", [AAp1], is used for the implementation the package name is "Graph::RandomMaze".

Usage

Rectangular maze

use Graph::RandomMaze;

my %rect = random-maze(rows => 8, columns => 16, type => 'rectangular', properties => Whatever);

my %opts = engine => 'neato', :8size, vertex-shape => 'point', edge-thickness => 12;
%rect<walls>.dot(|%opts):svg;

Hexagonal maze

my %hex = random-maze(rows => 8, columns => 16, type => 'hexagonal', properties => Whatever);

%opts<edge-thickness> = 32;
%hex<walls>.dot(|%opts):svg;

The returned hash contains:

• Carved wall graph (walls),

• Spanning tree used for carving (paths),

• Shortest-path solution (solution),

• Bookkeeping keys (shape, dimensions, start, end)

CLI

The package provides the Command Line Interface (CLI) script random-maze for making random mazes and exporting them in different formats. Here is the usage message:
