dragon-curve-cli

Print the Dragon Curve to the console!

Why the console? Because it's the cool way.

See All Fractals in the fractals-cli project.

Usage

Via npx:

$ npx dragon-curve-cli <n>
$ npx dragon-curve-cli <n> [options]

where n >= 0.

Via Global Install

$ npm install --global dragon-curve-cli
$ dragon-curve-cli <n>
$ dragon-curve-cli <n> [options]

where n >= 0.

Via Import

$ npm install dragon-curve-cli

then:

const dragon_curve = require('dragon-curve-cli');
console.log(dragon_curve.create(<n>);
console.log(dragon_curve.create(<n>, { 
    inverse: <boolean>,
    rotation: <left|right|flip|standard>,
    line: <bold|double|standard> 
});

The config params are optional.

Options

Recursive Step

$ dragon-curve-cli <n>

The first param <n> is the recursive step. <n> should be an integer greater than or equal to 0.

Examples:

$ dragon-curve-cli 7

$ dragon-curve-cli 9

Inverse

$ dragon-curve-cli <n> --inverse

The optional --inverse param (or shorthand -i) will draw the inverse Dragon Curve.

Example:

$ dragon-curve-cli 9 --inverse

Rotation

$ dragon-curve-cli <n> --rotate=<left|right|flip|standard>

The optional --rotate param rotates the Dragon Curve. Supported values:

• left: Rotate left 90 degrees
• right: Rotate right 90 degrees
• flip: Rotate 180 degrees
• standard: No rotation (default)

Example:

$ dragon-curve-cli 9 --rotate=right

$ dragon-curve-cli 9 --rotate=flip

$ dragon-curve-cli 9 --rotate=left

Line Type

$ dragon-curve-cli <n> --line=<bold|double|standard>

The optional --line param draws the Dragon Curve using different line types. Supported values:

• bold: Draw using bold lines
• double: Draw using double lines
• standard: Draw using standard lines (default)

Examples:

$ dragon-curve-cli 9 --line=bold

$ dragon-curve-cli 9 --line=double
