GitHubリリースについて

リリースページ には、ストア版のミラーに加え、Scratch Addonsの開発版のコードとインストールファイルがあります。

リポジトリのクローン

This is the recommended way to install Scratch Addons for development purposes, assuming you have Git installed.

If you plan on contributing, fork the repository on GitHub first and then clone the fork, replacing <username> with your Github username.

$ git clone https://github.com/<username>/ScratchAddons.git

Scratch Addonsを更新するには、フォルダー内に cd し、次のコマンドを実行してください:

$ git fetch
$ git pull

Remember to also update Scratch Addons from the browser.

Downloading the Zip

This method is not recommended for development unless Git cannot be installed on the system since it will need to be manually repeated every time you update Scratch Addons.

If you don not have Git installed, use this method instead.

  1. リポジトリ にて、ダウンロードボタンを押します。

  2. クリックし、「Download ZIP」を選択します。

  3. アーカイブをフォルダーに解凍します。

Google ChromeやMicrosoft Edge上でのインストール

To load the extension into Google Chrome and most Chromium-based browsers such as Microsoft Edge, Opera, Brave or Vivaldi:

  1. Go to chrome://extensions

  2. Turn on “Developer mode” in the top-right corner

  3. Click “Load unpacked” and select the ScratchAddons folder.

To update the extension when testing, click the refresh icon on the extension’s card.

The “Unrecognized manifest key” warnings may safely be ignored, since they are required by Firefox.

Mozilla Firefox上でのインストール

To load the extension into Mozilla Firefox:

Addons loaded into Firefox this way are temporary and must be reloaded every time the browser is restarted. Because of this Chrome is recommended for development, but everything is still expected to work on Firefox.
  1. Go to about:debugging

  2. Click “This Firefox” on the sidebar

  3. Click “Load Temporary Add-on…”

  4. Select the manifest.json file in the ScratchAddons folder.

  5. If a permission tab opens, click the “Enable” button.

To reload the extension when testing, click the “Reload” button on the extension’s card.

The unexpected WebExtension manifest property warnings may safely be ignored, since they are required by Chrome.
