- Provide errors in adequate datastructure to visualisation components (linenumber, type of error, further information)
- On error, parser should call event handler provided by visualization components
Visualization
- Provides event handler and register it to parser error-event
- Underline syntax errors using a (preferably wavy) red line
- On mouse over, show information on error
- Information window could be clickabel to provide further error information
