The aim is to be able to generate perfect mazes - mazes that are always solve-able for any pair of cells in the maze with the additional property that there exists a unique solution for that pair. In addition, solve the maze for the given scenarios:
Chart the path from the top-left to the bottom-right of the maze.
Discover a longest path in the maze.
Discover a most convoluted path in the maze.
The project will generate randomly shaped mazes for every run of the program (within reason).
For the design of the project, please refer to the Design doc.
This project is written in Rust (version: rustc 1.28.0 (9634041f0 2018-07-30)). Rust uses cargo as the build/dependency manager, and rustup as the tool for installing
Rust toolchains.
To set up Rust, please follow the following steps:
Go to the rustup.rs site to install the latest version of rustup using the command shown on the site:
curl https://sh.rustup.rs -sSf | sh
Following the default options should install the toolchain management tool, rustup. Note that you can pick from amongst a
number of preset toolchains - stable, nightly, and some others. Choose stable (nightly should work fine as well though).
Verify that the installation went through fine:
$ cargo --version
cargo 1.28.0 (96a2c7d16 2018-07-13)
Note: This project should work both with all Rust editions - 2015 or 2018.
From the project root, run the following command: cargo clean && cargo build --release as in:
``` $ cargo clean && cargo build --release Compiling libc v0.2.43 Compiling randcore v0.2.1 Compiling rand v0.5.5 Compiling mazeproject v0.1.0 (file:///Users/z0ltan/Code/Projects/games/maze_rs) Finished release [optimized] target(s) in 4.59s
```
Rust comes with its own documentation tool (much like javadoc) built-in. To generate the project documentation, run
the following command: cargo doc --no-deps --open as in:
$ cargo doc --no-deps --open

Launching open
This should open the generated HTML page in your default browser.
To run the project, use the cargo run command with any parameters passed in, like so:
$ cargo run
Finished dev [unoptimized + debuginfo] target(s) in 0.03s
Running `target/debug/maze_project`
Usage: cargo run HEIGHT WIDTH
Rust comes with its own test suite built-in, and the cargo test command should run all tests in the project:
``` $ cargo test Finished dev [unoptimized + debuginfo] target(s) in 0.03s Running target/debug/deps/maze_project-c360a1a0a2cd554c

Uses ANSI Escape Codes for rendering the maze, and so scrolling is a problem. Recommended limits are a 25 x 25 maze, but on bigger screens with greater resolutions and configurations, more or less should be possible. The code does not enforce any limit other than a minimum of a 1 x 1 maze size.
Again, due to the use of ANSI Escape Codes, the code should work fine on any ANSI-compliant terminal, and that rules out basic Windows command lines.
Most complicated Paths should be relatively straightforward to implement, and the planned approach is mentioned in the supporting Design doc.
All tweakable configurations (animation speeds, font colours, cell sprites et al) should ideally be placed in an external configuration file.
