Runnable and graded codeblocks

Runnable Ruby

Runnable Ruby with Additional Attributes

• readonly_lines

  • Some lines can be marked as “readonly”. The user will not be able to modify these lines. This attribute accepts an array of line numbers.

  • Example: readonly_lines="[10, 16, 17]"

• setup_code

  • A single line or a range of lines can be marked as setup code. These lines will not be shown to the user. The line numbers shown on the left margin of the code editor will not include those lines marked as setup_code.

  • Example: setup_code="1"

  • Example: setup_code="1-4"
