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 🙏

Readme

wavefont build

A typeface for rendering vertical bars data: waveforms, spectrums, diagrams, histograms, columns etc.

Playground  •  Google fonts  •  V-fonts  •   Wavearea

Usage

Place Wavefont[ROND,YELA,wght].woff2 into your project directory and use this code:

<style>
@font-face {
	font-family: wavefont;
	font-display: block;
	src: url(./Wavefont[ROND,YELA,wght].woff2) format('woff2');
}
.wavefont {
	--wght: 10;
	font-family: wavefont;
	font-variation-settings: 'wght' var(--wght), 'ROND' 30, 'YELA' 0;
}
</style>

<!-- Set values manually -->
<textarea id="waveform" class="wavefont" cols="100">
abcdefghijklmnopqrstuvwwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ
</textarea>

<script>
// Set values programmatically (more precise)
waveform.textContent = Array.from({length: 100}, (_,i) => String.fromCharCode(0x100 + i)).join('')
</script>

Ranges

Wavefont bars correspond to values from 0 to 100, assigned to different characters:

  • 0-9 chars are for simplified manual input with step 10 (bar height = number).
  • a-zA-Z for manual input with step 2, softened at edges a and Z (bar height = number of letter).
  • U+0100-017F for 0..127 values with step 1 (char = String.fromCharCode(0x100 + value)).

Variable axes

Tag | Range | Default | Meaning ---|---|---|--- wght | 1-1000 | 400 | Bar width, or boldness. ROND | 0-100 | 100 | Border radius, or roundness (percent). YELA | -100-100 | -100 | Alignment: bottom, center or top.

To adjust axes via CSS:

.wavefont {
  font-variation-settings: 'wght' var(--wght, 40), 'ROND' var(--rond, 0), 'YELA' var(--align, 0);
  letter-spacing: 1ch; /* 1ch unit === 1 bar width */
}

Features

  • Ranges, values and width is compatible with linefont, so fonts can be switched preserving visual coherency.
  • Visible charcodes fall under marking characters unicode category, ie. recognized as word by regexp and can be selected with Ctrl + or double click. Eg. waveform segments separated by or - are selectable by double click.
  • Characters outside of visible ranges are clipped to 0, eg. , \t etc.
  • -–._* map to 1 value, | maps to max value, ▁▂▃▄▅▆▇█ map to corresponding bars.
  • Accent acute  ́ (U+0301) shifts bar 1-step up, circumflex accent  ̂ (U+0302) 10-steps up. Eg. \u0101\u0302\u0302\u0301\u0301\u0301 shifts 23 steps up.
  • Accent grave  ̀ (U+0300) shifts bar 1-step down, caron  ̌ (U+030C) shifts 10 steps down, eg. \u0101\u030c\u0300\u0300\u0300 shifts 13 steps down.
  • Caret span is -20..120, so line-height = 1.4 is minimal non-overlapping selection.

JS package

To facilitate calculation, wavefont exposes a function that calculates string from values.

import wf from 'wavefont'

// get characters for values from 0..127 range
wf(0, 1, 50, 99, 127, ...) // ĀāIJţŤ...
