JigSass Tools Color

NPM version Build Status Dependency Status

Helpers for using and managing color palettes

Define and access named colors in a central palette

Installation

Using npm:

npm i -S jigsass-tools-color

Usage

@import 'path/to/jigsass-tools-color/scss/index';

Start by defining a color palette in the $jigsass-colors map.

You may define adjustment on each color by specifing a color function (or functions) directly in the map:

$jigsass-colors: (
  // Explicit colors
  black: #000,
  primary: #09a5d9,
  secondary: #046380,
  tertiary: #9f1626,
  neutral: #2d2d2d,

  // Adjustments on explicit colors
  light-tertiary: #9f1626 complement,

  // Aliases
  text-link: secondary,

  // Adjustments to existing colors
  gutter-rule: secondary (tint: 3),

  // Multiple adjustments
  headline: primary (shade: 1) complement,
///   )

You can now access colors, using the same syntax used for defining them to begin with.

.foo {
   bar: jigsass-color(black (tint: 20%)); // --> #333
}

For consistency, you can define per-color-function adjustment steps (documentation):

$jigsass-adjustment-steps: (
  // Tint will be increamented by 10% at every step
  tint: 10%,
  // Lighten has predefined steps
  lighten: 2% 14% 34% 45%,
  // Used for all color function with no explicitly defined steps
  default: 5%,
);

And then access them in the jigsass-color function and $jigsass-colors map by passing a unitless number to the color functions:

.bar {
  // Tint `black` by two steps
  baz: jigsass-color(black (tint: 2));  // --> #333
}

See the documentation for a full overview of JigSass Color's functionality.

Development

It is a best practice for JigSass modules to not automatically generate css on @import, but rather have to user explicitly enable the generation of specific styles from the module.

Contributions in the form of pull-requests, issues, bug reports, etc. are welcome. Please feel free to fork, hack or modify JigSass Tools Color in any way you see fit.

Writing documentation

Good documentation is crucial for scalability and maintainability. When contributing, please do make sure that all Sass functionality (functions, mixins, variables and placeholder selectors), is well documented.

Documentation will be auto generated from inline comments using SassDoc (Documention).

Running tests

gulp lint will, well, lint the contents scss files in the scss directory.

gulp test with run module's test using Mocha and Sassaby.

gulp tdd will watch both the Sass files and the test specs for changes, and will run tests automatically upon them.

Writing tests

JigSass Tools Color tests are written using Sassaby and Mocha. Spec files are located in the test directory.

Mocha allows us to place a call to before() in the root of any test file and it will be run once, before all the other tests in every test_*.js file. We can also require() files and assign them to the global object to make them available to all test_*.js files.

jigsass-tools-color uses a file called helper.js can be used to set up mocha globals requires and before().

In addition to Sassaby's testing functions, jigsass-tools-color makes a few Sass functions available to the test suite, for use inside Sassaby tests:
