Helpers for using and managing color palettes
Define and access named colors in a central palette
Using npm:
npm i -S jigsass-tools-color
@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 $jigsass-colors
map by
passing a unitless number to the color functions:
.bar {
// Tint `black` by two steps
baz: jigsass-color(black (tint: 2)); // --> #333
}
See the documentation for a full overview of JigSass Color's functionality.
It is a best practice for JigSass modules to not automatically generate css on @import
, but
rather have to user explicitly enable the generation of specific styles from the module.
Contributions in the form of pull-requests, issues, bug reports, etc. are welcome. Please feel free to fork, hack or modify JigSass Tools Color in any way you see fit.
Good documentation is crucial for scalability and maintainability. When contributing, please do make sure that all Sass functionality (functions, mixins, variables and placeholder selectors), is well documented.
Documentation will be auto generated from inline comments using SassDoc (Documention).
gulp lint
will, well, lint the contents scss files in the scss
directory.
gulp test
with run module's test using Mocha and Sassaby.
gulp tdd
will watch both the Sass files and the test specs for changes, and will
run tests automatically upon them.
JigSass Tools Color tests are written using Sassaby
and Mocha. Spec files are located in the test
directory.
Mocha allows us to place a call to before()
in the root of any test file and it
will be run once, before all the other tests in every test_*.js
file.
We can also require()
files and assign them to the global object to make them
available to all test_*.js
files.
jigsass-tools-color uses a file called helper.js
can be used to set up mocha
globals requires and before()
.
In addition to Sassaby's testing functions, jigsass-tools-color makes a few Sass functions available to the test suite, for use inside Sassaby tests:
- jig-var-equals($value, $var) -> {boolean}
-
Check if a variable equals a value.
$value {*}: A value to compare the value of $var to.
$var {*}: The variable to test
- jig-var-type-is($type, $var) -> {boolean}
-
Check if a variable is of a certain type.
$type {string}: A type to compare with the type of $var.
$var {*}: The variable to test
- jig-map-key-equals($value, $map, $keys...) -> {boolean}
-
Check if a map's key is assigned a cerain value.
$value {*}: A value to compare the value of a key in $map with.
$map {map}: The map to test.
$keys... {arglist}: A recursive chain of keys.
- jig-map-key-type-is($type, $map, keys...) -> {boolean}
-
Check if a map's key is of a certain type
$type {string}: A type to compare with the type of $var.
$map {map}: The map to test.
$keys... {arglist}: A recursive chain of keys.
