Guiding principle: put as much in the URL as is reasonable.

Things that happen:

Worksheet:

  • introspection
  • create cells
  • delete cells
  • join cells
  • split
  • hide cells

Cell:

  • change input
  • evaluate
  • get_output('start'=0)
    • -- 'start' - offset telling how much text we've already received -- output:
      • --'status' --'output'

JSON <---> HTTP

HTTP Requests:

Structure of URL:

/home/ username / worksheet_num / cell_id /..

  • ../update

JSON Messages:

  • 'id' : id

  • 'status' : 'success' or 'failure'

Database Calls:

  • increase_worksheet_state_number()

  • update_cell_input(cell_id, input_text)

  • evaluate_cell(cell_id)

  • insert_after_cell(cell_id)
