Module Presented And Duplicated Check

Termeh provides utilities to manage custom modules. It allows you to check if a required module is loaded and throws an error if not. You can also register modules as loaded and check if a module has been presented.

Present Module

Adds a module to the global presented modules list.

Signature:

@mixin present-module($module: STRING);

Example:

@include use-toast() {
  // Skip define if module already defined
  @if not termeh.module-presented("toast") {
    // Register module to ignore duplicate call
    @include termeh.present-module("toast");

    @at-root {
      .toast {
        // ...
      }
    }
  }
}

Required Module Check

Validates that required modules are present. Throws an error if any required module is missing.

Signature:

@mixin require($module: STRING, $requirement: STRING);

Example:

@include use-notification() {
  @include termeh.require("notification", "toast");

  @if not termeh.module-presented("notification") {
    @include termeh.present-module("notification");
    @at-root {
      .notification {
        @extend .toast;
        // ...
      }
    }
  }
}

Module Presented Check

Checks whether a module has been presented (added) or not.

Signature:

@function module-presented($module: STRING): BOOLEAN;

Example:

@include use-toast() {
  @if not termeh.module-presented("toast") {
    @at-root {
      .toast {
        // styling only applied if module not registered
      }
    }
  }
}
