Add a new feature

To add a new feature, please follow these guidelines.

Note: I will probably make this automated in the future but it's a bit of work right now.

Identifier

• Should be a unqiue one/two word storage identifier to indicate its status. (ie "dark_mode" or "dashboard_grades")
• If it has sub options (options that are specific to the main feature) these will also each need a unique identifier.
• All options are synced and have a 8kb storage limit, so if your feature needs more than this please contact me.

Changes to html/popup.html

• Add the appropriate HTML into this file. The corresponding id and name (see below) should be the identifier.
• If it has no sub options, it should be put in the same container as the other options with no sub options:

<div class="option" id="<identifier>">
    <input type="radio" id="off" name="<identifier>">
    <input type="radio" id="on" name="<identifier>">
    <div class="slider">
        <div class="sliderknob"></div>
        <div class="sliderbg"></div>
    </div>
    <span class="option-name"><option name></span>
</div>

• If it does have sub options it becomes it's own container:

<div class="option-container">
  <div class="option" id="<identifier>">
    <input type="radio" id="off" name="<identifier>">
    <input type="radio" id="on" name="<identifier>">
    <div class="slider">
      <div class="sliderknob"></div>
      <div class="sliderbg"></div>
    </div>
    <span class="option-name"><option name></span>
  </div>
  <div class="sub-options">
    <div class="sub-option">
      <input type="checkbox" id="<sub identifier>" name="<sub identifier>">
      <label for="<sub identifier>" class="sub-text"><option name></label>
    </div>
  </div>
</div>

Changes to js/popup.js

• Add the main identifier into the syncedSwitches array.
• If you have sub-options:
  • Add these identifiers to the array found under the comment that says //checkboxes.

Changes to js/background.js

• Add all identifiers into the syncedOptions array.
• Add a default value for your option to the default_options array.
  • Preferably this value should be false for booleans or "" for strings (null can also be used if Canvas has a default for this option already)

Changes to js/content.js

• There should be a function(s) included in the this file that does the work. The name should clearly indicate it's purpose.
• Under applyOptionsChanges(), add a switch case to call this function when the menu toggle is changed.
• Depending on what your feature does, it needs to be told when to fire.
  • If the function changes any aspect of the dashboard, it should be put inside checkDashboardReady().
  • If the function only adds css, it should be added to applyAestheticChanges(), and in this case should not be a separate function, instead add the css to the existing styles found in this function.
  • Anything else should be put under startExtension() and should be placed no higher than the checkDashboardReady function found here.

Add a new theme

To add a new theme, please follow these guidelines.

You can export a theme using the export tool in the menu and sending an email to me, or you can merge it here after doing the following:

Exporting

• Go to the Themes tab and export dark mode, card images, card colors, and custom font. - The only on/off toggles that need be included are disable_color_overlay and gradient_cards. Any other toggles aren't necessary, so you should manually add these keys and the appropriate values in with the export code.
• Pick a unique id for the theme, doesn't matter how long this is.

Changes to js/popup.js

• Add the export code under getTheme().
  • Make sure it follows this format: "theme-<id>: { "exports": {"..."}, "preview": "..." }
• For the preivew, try to pick the smallest image size from the card images (under ~50kb is perfect), or you can find a smaller display image that isn't included in the card images.

Changes to html/popup.html

• Add the following under all the other theme buttons:

<button id="theme-<id>" class="theme-button customization-button"><theme name> by <you></button>

• The theme name should be one/two words so it doesn't take up too much space.
