Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

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

See All Fractals in the fractals-cli project.

Usage

Via npx:

$ npx sierpinski-arrowhead-cli <n>
$ npx sierpinski-arrowhead-cli <n> [size] [options]

where n >= 0 and size >= n (if provided).

Via Global Install

$ npm install --global sierpinski-arrowhead-cli
$ sierpinski-arrowhead-cli <n>
$ sierpinski-arrowhead-cli <n> [size] [options]

where n >= 0 and size >= n (if provided).

Via Import

$ npm install sierpinski-arrowhead-cli

then:

const sierpinski = require('sierpinski-arrowhead-cli');
console.log(sierpinski.create(<n>));
console.log(sierpinski.create(<n>, { 
    size: <number>, 
    rotate: <left|right|standard>, 
    line: <bold|standard> 
}));

The config params are optional.

Options

Recursive Step

$ sierpinski-arrowhead-cli <n>

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

Examples:

$ sierpinski-arrowhead-cli 4

What sierpinski-arrowhead-cli prints to the console

$ sierpinski-arrowhead-cli 5

What sierpinski-arrowhead-cli prints to the console

Size

$ sierpinski-arrowhead-cli <n> [size]

The optional [size] param allows the Sierpinski Arrowhead Curve to be drawn at larger sizes. [size] should be an integer greater than or equal to <n>. Including size will draw a Sierpinski Arrowhead Curve of <n> recursive steps the size of a Greek Cross fractal with [size] recursive steps.

Example:

$ sierpinski-arrowhead-cli 3 5

What sierpinski-arrowhead-cli prints to the console

Rotation

$ sierpinski-arrowhead-cli <n> --rotate=<left|right|standard>

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

  • left: Rotate left 120 degrees
  • right: Rotate right 120 degrees
  • standard: No rotation (default)

Example:

$ sierpinski-arrowhead-cli 5 --rotate=right

What sierpinski-arrowhead-cli prints to the console

$ sierpinski-arrowhead-cli 5 --rotate=left

What sierpinski-arrowhead-cli prints to the console

Line Type

$ sierpinski-arrowhead-cli <n> --line=<bold|standard>

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

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

Examples:

$ sierpinski-arrowhead-cli 5 --line=bold

What sierpinski-arrowhead-cli prints to the console

By default, lines are drawn using long unicode slash characters (, ). To instead draw using standard slash characters (/, \ ), add the --slash param (or shorthand -s).

$ sierpinski-arrowhead-cli <n> --slash

(May look better/worse on certain terminals)
