kishtarn555 / ReKarel

Rework of omegaup's Karel.js.

It's main reason is so it works in mobile, currently it doesn't because

• CodeMirror 5 isn't mobile compatible
• WorldRenderer scroll doesn't work on all devices
• It is not responsive, toolbar is gone in mobile

This new version includes:

• Now with bootstrap 5
• Now with CodeMirror 6

Features from Karel.js

Migrations

• Migrated to Bootstrap 5.0.2
• Migrated to JQuery 3.6.1
• Migrated to CodeMirror 6
• Migrated Split.js

Deprecated

• Removed Karel Ruby as it didn't worked and it seemed to be in route of deprecation.

Mobile

• Supports touch control on both views.
• UI changes to one better suited for small screens, similar to "Karel blue", aka Karel.exe
• CodeEditor maybe edited without writing.

Quality of live

• Settings that allow to set:
  • Prefered programming language (default is auto as Karel.js)
    • If set, syntax higlighting and compile will always try that language.
  • The view (force one view independent of screen size)
  • Code Font size
• Hotkeys
  • Ctrl+K Decreases editor's font.
  • Ctrl+L Increases editor's font.
• Added the ability to zoom in and out of the world.
• Native scrolling with scrollbars for the world renderer.
  • The previous scroll was hard to use imo.
• Added the ability to specify the name of the file to be downloaded
• Added clean button to remove old messages.
• "Are you sure?" before reseting code
• "Are you sure?" before reseting world
• Added icons to Karel position.

World Editor

Reworked world editor.

Now it is more similar to Google's spreadsheet

• World edition is based on cell selection and a toolbar.
