(notes for introducing activation columns)

[sverweij]

a basic scenario

Handling proper arrow endings properly

Handling colors

Integrating ...

Re-activation?

Activation on self reference?

TODO

some pseudo code

// pEntity state machine:
initial     -> inactive;
inactive    -> activated  : activate; // WHERE?
activated   -> active     : initial activation rendered; // HERE
active      -> deactivated: deactivate; // WHERE?
deactivated -> inactive   : deactivation rendered; //HERE

        /* switch (pEntity.state) {
            case 'activated':
                render activation line top
                pEntity.state = 'active';
                break;
            case 'active':
                render activation line continuation
                break;
            case 'deactivated':
                render activation line bottom
                pEntity.state = 'inactive'
                break;
        }

auto activation scenarios
