Package Exports

stylelint-config-plural
stylelint-config-plural/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (stylelint-config-plural) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Plural's Javascript Styleguide

🎨 How plural paints its styles.

Extends:

Turns on additional rules to enforce common conventions found in the specifications and in a handful of CSS styleguides, including: BEM CSS.

It favors flexibility over strictness for things like multi-line lists and single-line rulesets.

To see the rules that this config uses, please read the config itself.

Example

@import "x";
@import "y";

/**
 * Multi-line comment
 */

:root {
  --brand-red: hsl(5deg 10% 40%);
}

.selector-1,
.selector-2,
.selector-3[type="text"] {
  background: linear-gradient(#fff, rgb(0 0 0 / 80%));
  box-sizing: border-box;
  display: block;
  color: var(--brand-red);
}

.selector-a,
.selector-b:not(:first-child) {
  padding: 10px !important;
  top: calc(100% - 2rem);
}

.selector-x { width: 10%; }
.selector-y { width: 20%; }
.selector-z { width: 30%; }

/* Single-line comment */

@media (width >= 60em) {
  .selector {
    /* Flush to parent comment */
    transform: translate(1, 1) scale(3);
  }
}

@media (orientation: portrait), projection and (color) {
  .selector-i + .selector-ii {
    background: hsl(20deg 25% 33%);
    font-family: Helvetica, "Arial Black", sans-serif;
  }
}

/* Flush single line comment */
@media
  screen and (min-resolution: 192dpi),
  screen and (min-resolution: 2dppx) {
  .selector {
    animation: 3s none fade-in;
    background-image:
      repeating-linear-gradient(
        -45deg,
        transparent,
        #fff 25px,
        rgb(255 255 255 / 100%) 50px
      );
    margin: 10px;
    margin-bottom: 5px;
    box-shadow:
      0 1px 1px #000,
      0 1px 0 #fff,
      2px 2px 1px 1px #ccc inset;
    height: 10rem;
  }

  /* Flush nested single line comment */
  .selector::after {
    content: "→";
    background-image: url("x.svg");
  }
}

@keyframes fade-in {
  from { opacity: 0; }
  to { opacity: 1; }
}

Note: the config is tested against this example, as such the example contains plenty of CSS syntax, formatting and features.

Installation

npm install stylelint-config-plural --save-dev

Usage

Set your stylelint config to:

{
  "extends": "stylelint-config-plural"
}

Extending the config

Add a "rules" key to your config, then add your overrides and additions there.

You can turn off rules by setting its value to null. For example:

{
  "extends": "stylelint-config-plural",
  "rules": {
    "selector-class-pattern": null
  }
}

Or lower the severity of a rule to a warning using the severity secondary option. For example:

{
  "extends": "stylelint-config-plural",
  "rules": {
    "property-no-vendor-prefix": [
      true,
      {
        "severity": "warning"
      }
    ]
  }
}

A more complete example, to change the at-rule-no-unknown rule to use its ignoreAtRules option, change the indentation to tabs, turn off the number-leading-zero rule, set the severity of the number-max-precision rule to warning, and add the unit-allowed-list rule:

{
  "extends": "stylelint-config-plural",
  "rules": {
    "at-rule-no-unknown": [
      true,
      {
        "ignoreAtRules": ["--my-at-rule"]
      }
    ],
    "indentation": "tab",
    "number-leading-zero": null,
    "number-max-precision": [
      4,
      {
        "severity": "warning"
      }
    ],
    "unit-allowed-list": ["em", "rem", "s"]
  }
}

Improving this config

Consider adding test cases if you're making complicated rules changes, like anything involving regexes. Perhaps in a distant future, we could use literate programming to structure our README as test cases for our .eslintrc?

You can run tests with npm test.

You can make sure this module lints with itself using npm run lint.
