New Python Packaging Proposal Aims to Solve Phantom Dependency Problem with SBOMs
PEP 770 proposes adding SBOM support to Python packages to improve transparency and catch hidden non-Python dependencies that security tools often miss.

I needed library that:
There was no library that matched these requirements.
This library is available in 2 languages to make it usable in both client side web components and server side scripts:
Library has only 1 object: Color
Color object represents color. You can:
Class automatically converts between color spaces when needed.
Code is optimized for performance. Unusual coding style was used to make code consistent between different programming languages.
How to include library:
// For Node.js
const CAColor = require('@cyberalien/color');
// For browser (change path to correct url)
// <script src="./dist/color-es5.js"></script>
Sample code:
var color, color2;
// Create simple color object, get HEX string
color = new CAColor();
color.setRGB(10, 20, 30);
color.toHex();
// Create color object from string
color = CAColor.fromString('rgba(10, 20, 30, .5)');
color.getRGBA();
// Change color components in different color spaces
color = CAColor.fromString('#f00');
color.setHue(180);
color.toString(); // '#00ffff'
color.toHex(true); // '#0ff' - compressed hex string
// Mix colors
color = CAColor.fromString('blue');
color2 = CAColor.fromString('red');
color.mix(color2, 50); // 50% of each color
color.toKeyword(); // 'purple'
// Manipulate color spaces
color = CAColor.fromString('yellow');
color.setHue(color.getHue() + 180);
color.setLightness(25);
color.toHex(); // '#000080'
color.toHSLString(); // 'hsl(240, 100%, 25%)'
// Calculate contrast between 2 colors
color = CAColor.fromString('yellow');
color2 = CAColor.fromString('darkblue');
color.getContrast(color2); // 14.245...
Documentation will be added later, when new website is ready.
For now you can easily figure it out by reading function names and docblocks in src/color.js or lib/color.php. Code is well documented.
Color values use following ranges:
JavaScript library is written in ES6, but is compiled into ES5 code for older browsers.
PHP library requires PHP 5.4 or newer version.
To re-compile library you need Node.js. Open Terminal or command prompt, run these commands:
npm install
grunt
First command will install all necessary libraries. Second command will compile libraries.
If you are having problems getting Grunt to execute, install it globally:
npm install -g grunt
To run tests run this command:
npm test
This library is licensed under MIT license. That means you can use it in both open source and commercial projects.
