Provide adequate, but non intrusive feedback to user about syntax errors.
Parser
# Should only parse when neccessary, using timer function or after certain input (like spaces, enter) (to be further specified ) # 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
