Usage

Place [_Wavefont[ROND,YELA,wght].woff2_](./fonts/variable/Wavefont[ROND,YELA,wght].woff2) into your project directory and use this code:

``html



<br />abcdefghijklmnopqrstuvwwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ<br />


`

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:
`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.

`js
import wf from 'wavefont'

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