    JigSass Tools Bidi

    NPM version Build Status Dependency Status

    Painless bidirectional style authoring

    Installation

    Using npm:

    npm i -S jigsass-tools-bidi

    Usage

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

    Managing bi-directionality in CSS can be an annoying, time consuming and error-prone task.

    JigSass Bidi was written to make this process as simple as possible, without sacrificing flxibilty. It eases the process of writing clean and maintainable bidirectional style sheets by using a single mixin to handle transformation of all direction-related styles (values and/or properties) by automatically interpreting directions as start`endinstead ofleft\right`.

    Configuration

    JigSass Bidi has only two configuration variables:

    • $jigsass-direction, which can be set to either ltr (default) or rtl. JigSass Bidi will determine how to interpert what start/end means, and transform values accordingly documentation.
    • $jigsass-bidi-rem-default, which determines if pixel values should be automatically converted into rem unit. This setting can be overriden individually at every call to the jigsass-bidi mixin by passing true or false to the $rem argument (documentation).

    Mixins

    • jigsass-bidi
      takes 4 arguments: $property, $values, $bps and $rem (documentation).
    • jigsass-bidi-direction
      Temporarily set the direction for the context of the mixin's execution (documentation).

    Caveats

    • The background shorthand is not supported. Set the background-image and background-position properties directly.
    • When multi-dimensional lists are passsed to to $values argument (e.g., to border-radius, box-shadow, text-shadow or background-position), They should be passed as space separated lists inside a comma-separated list.
    • The X argument of backgrond-position and transform-origin can be transformed only if set to start, end or a number in percentage (%). transforming non-relative widths requires knowledge of the container's dimensions.

    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 Bidi 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 is auto-generated using SassDoc

    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 Bidi 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-bidi 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-bidi 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.
