@mitchallen/maze2openscad-cli

Code generate a maze as an OpenSCAD include file via the command line

Installation

You must use npm 2.7.0 or higher because of the scoped package name.

This is the command line version of the module @mitchallen/maze2openscad.

Because this is a command line tool, you should install it using the -g flag. This may require starting the command with sudo.

$ npm install -g @mitchallen/maze2openscad-cli

Usage

• If you don't have a copy of OpenSCAD you can download it for free from here: http://www.openscad.org
• Create a new test folder and change to it
• Browse to: https://github.com/mitchallen/maze2openscad-cli/

Square Maze

• Find the file maze.scad in the root of the project and make a local copy of it.
• Edit the include path at the top of the file and change it to:

include <demo-maze-data.scad>

• The demo-maze-data.scad file will be generated by the tool
• To generate a maze include file with data for 10 columns and 20 rows do this:

$ maze2openscad-cli square 10 20 demo-maze-data.scad

• Start OpenSCAD and open maze.scad
• You should see a generated maze
• Leave OpenSCAD running and run the command line again to see a new maze appear in OpenSCAD

Circle Maze

• Find the file maze-circle.scad in the root of the project and make a local copy of it.
• Edit the include path at the top of the file and change it to:

include <demo-circle-maze-data.scad>

• The demo-circle-maze-data.scad file will be generated by the tool
• Create a subfolder called input
• Copy the test/input/circle-demo.json file from the repo to that folder
• To generate a maze include file with data for a circular maze run this command (you must use an absolute path for the first parameter - substitute your-project with your project folder):

$ maze2openscad-cli circle ~/your-project/input/circle-demo.json \
demo-circle-maze-data.scad

Windows users may need to adjust the input path to use drive letters, etc.

• Start OpenSCAD and open maze-circle.scad
• You should see a generated maze
• Leave OpenSCAD running and run the command line again to see a new maze appear in OpenSCAD

Circle Options

• See test/input/circle-demo.json in the repo for an example of how to create option files for circlular mazes.
• The circle input file must be a valid JSON file with the following parameters:

{
    "rings": 5,
    "ringHeight": 6,
    "ringThickness": 1.5,
    "outerThickness": 3,
    "ringCutWidth": 5,
    "innerRadius": 6,
    "middleRadius": 18,
    "middleHole": false,
    "spokeWidth": 0.5,
    "hasFloor": false,
    "floorHeight": 2
}

• Feel free to change the values to generate various types of mazes.

JSON Validator

To make sure that your circle maze input file is valid, paste it into an online JSON validator, like this one: https://jsonlint.com/

Testing

To test, go to the root folder and type (sans $):

$ npm test
