Stylup

Stylup gives your markup super powers.

Example

Use to write inteligent functional classes based on their arguments.

<div class="p-4,1,*"></div>

Transforms into styles based on your configuration.

<style>
.80YQhjgv {
  --pt: 4;
  --pr: 1;
  --pl: 1;
}
</style>
<div class="p 80YQhjgv"></div>

You can configure class functions to output whatever you like.

When used with a stylesheet it becomes very powerful, requiring minimal pre configuration to work with your design system.

.p {
  padding-top: calc(var(--pt, initial) * 1rem);
  padding-right: calc(var(--pr, initial) * 1rem);
  padding-bottom: calc(var(--pb, initial) * 1rem);
  padding-left: calc(var(--pl, initial) * 1rem);
}

Features

• Functional Class Names

  Use inteligent functional class names. Seperate arguments with commas. Use a wildcard to skip arguments. See below for configuring your own class names.

  <div class="p-4 m-*,auto fl-wrap"></div>
  

---

• Inline Styles

  Make use of all CSS features inline including hover states and media queries.

  <div style="&:hover { color: red; }"></div>
  

---

• Supports PostCSS

  Add support for PostCSS by including a postcss.config.js file in your project.

---

• Custom Syntax

  Customise the syntax used for functional classes by by overiding the default regex pattern. stylup.process(html, null, options);

  // Options
  let options = {
    regex: {
      property: /[^-\s]+/,
      number: /[0-9]*\.?[0-9]+|\*/,
      unit: /px|cm|mm|in|pt|pc|em|ex|ch|rem|vw|vh|vmin|vmax/,
      seperator: /,/,
      arg: /0*({{number}})({{unit}})?|(\w+)/,
      args: /(?:({{arg}}){{seperator}}?)+/,
      decl: /({{property}})(?:-({{args}}))?/
    	};
  }
  

Configure

By default stylup will look for a file called stylup.config.js at the root of your project.

// phtml-utility-class.config.js
module.exports = {
  classes: [
    {
      class: 'p',
      children: [
        't',
        'r',
        'b',
        'l'
      ],
      style: ({ property, children, args, str }) => {

        if (args.length < 3) args.push(args[0])
        else args.push(args[1])

        for (let [i, side] of children.entries()) {
          str`--${property}${side}: ${args[i]};`
        }

        return str()
      }
    }
    // ...
  ]
}

Usage

Add stylup to your project:

npm install stylup --save-dev

Use stylup to process your HTML:

const stylup = require('stylup');

stylup.process(YOUR_HTML /*, processOptions, pluginOptions */);

Or use it as a pHTML plugin:

const phtml = require('phtml');
const stylup = require('stylup');

phtml([
  stylup(/* pluginOptions */)
]).process(YOUR_HTML /*, processOptions */);

Options

By default block styles are not processed. Set this to true to process them. stylup.process(html, null, options).

// Options
let options = {
  processBlockStyles: true
}
