edscratchczech

Browser plugin for Edison Edscratch with Czech localization. Works for three different versions of Edison Edscratch:

• Edison Edscratch v3
• Edison Edscratch v2
• "Cloud" version of Edison Edscratch

How does it works?

There are two ways the plugin translates Edison Edscratch into Czech language.

The first one (file translate_dom.js) looks for HTML elements having specific class attribute set and replaces their content with Czech words. This translates top left navigation with block types. This file is needed for Edison Edscratch v2 and "cloud" version of Edison Edscratch.

The second one (file block_rules.json) replaces four JavaScript files downloaded to the browser as part of the Edison Edscratch application with their copy having texts translated into Czech. This translates the blocks and warning and error messages. This is needed for all Edison Edscratch versions.

How to create your own Edison Edscratch translation plugin

To translate Edison Edscratch into your language:

1. In translate_dom.js file look at the switch statement and for each option replace Czech words assigned to translation variable with words in your language.
2. Download following original JavaScript files:
   • https://www.edscratchapp.com/v2/js/blockly_compressed_vertical.js
   • https://www.edscratchapp.com/v2/js/blocks_compressed_vertical.js
   • https://www.edscratchapp.com/v3/errorMessages.js
   • https://www.edscratchapp.com/v3/msg/messages.js
3. In errorMessages.js file translate string values in both Blockly.redErrorMessages and Blocky.yellowErrorMessages objects. In our plugin the translated file is saved as errorMessages_czech.js.
4. Translating blocks is bit more complicated.
   • For Edison Edscratch v2 and "cloud" version: Open Edison Edscratch app, go through all the block types and search block texts one by one in blockly_compressed_vertical.js and blocks_compressed_vertical.js files and translate them. In our plugin the translated files are also saved with czech suffix.
   • For Edison Edscratch v3: Open Edison Edscratch app, go through all the block types and search block texts one by one in messages.js and blockly_compressed_vertical.js files and translate them. The majority of texts is stored in messages.js file but options for a few combo boxes are still placed in the second file. In our plugin the translated files are also saved with czech suffix.
5. Save all translated JavaScript files, open block_rules.json file and replace extensionPath properties in all rules with path to your translated files.
6. Open manifest.json file, update plugin name, version and description and change resources in web_accessible_resources section to match paths of your translated JavaScript files.
7. Create your own tile and icon images.
