    JigSass Tools Maps

    NPM version Build Status Dependency Status

    Map helper functions


    Using npm:

    npm i -S jigsass-tools-maps


    @import 'path/to/jigsass-tools-maps/index.scss'; should give you all you need.

    jigsass-tools-maps provides the following utility functions:

    Get a value from nested maps
    Set a value in nested maps
    Check if a map has a nested key
    Recursively assign values from multiple maps into a single map

    For further details, see the documentation located in The sassdoc directory.


    Documentation of JigSass Tools Maps's Sass features is generated by SassDoc.

    Run gulp serve:sassdoc to fire up a live server serving the documentation.

    To generate documentation from annotation in the source code, run gulp sass:doc.

    To disable the generation of sass documentation, create an empty noSassDoc file at the root jigsass-tools-maps directory.


    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 Maps in any way you see fit.

    Writing documentation

    Good documentation is crucial for scalability and maintainability. When writing your module, please do make sure that both its Sass functionality (functions, mixins, variables and placeholder selectors), as well as the CSS it generates (selectors, concepts, usage exmples, etc.) are well documented.

    As mentioned above, the Sass is documented 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 Maps 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-maps 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-maps 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.
