|
||
|
|
||
|
|
||
|
## Primitives
|
||
|
|
||
|
- `step :: Karel -> Karel`<br>
|
||
|
Moves Karel one intersection forward
|
||
|
- `turnLeft :: Karel -> Karel`<br>
|
||
|
Pivots Karel 90 degrees left
|
||
|
- `pickBeeper :: Karel -> Karel`<br>
|
||
|
Takes a beeper from the current intersection and puts it in the beeper bag
|
||
|
- `putBeeper :: Karel -> Karel`<br>
|
||
|
Takes a beeper from the beeper bag and puts it at the current intersection
|
||
|
|
||
|
|
||
|
## Sensors
|
||
|
|
||
|
- `frontIsClear :: Karel -> Bool`<br>
|
||
|
Returns `True` if there is no wall directly in front of Karel. Returns `False` if there is a wall.
|
||
|
- `beepersPresent :: Karel -> Bool`<br>
|
||
|
Returns `True` if Karel is standing at an intersection that has a beeper, `False` otherwise
|
||
|
- `facingNorth :: Karel -> Bool`<br>
|
||
|
Returns `True` if Karel is facing north, `False` otherwise
|
||
|
- `beepersInBag :: Karel -> Bool`<br>
|
||
|
Returns `True` if there is at least one beeper in Karel's beeper bag, `False` if the beeper bag is empty
|
||
|
|
||
|
# Super Karel Language Reference
|
||
|
|
||
|
Super Karel is an extension to the basic Karel the Karel library. Super Karel is "equipped" with additional sensors.
|
||
|
|
||
|

||
|
- `leftIsClear :: Karel -> Bool`<br>
|
||
|
Returns `True` if there is no wall immediately to Karel's left, `False` if there is
|
||
|
- `leftIsBlocked :: Karel -> Bool`<br>
|
||
|
Returns `True` if there is a wall immediately to Karel's left, `False` otherwise
|
||
|
- `rightIsClear :: Karel -> Bool`<br>
|

Returns `True` if there is no wall immediately to Karel's right, `False` if there is
|
||
|
- `rightIsBlocked :: Karel -> Bool`<br>
|

|
||
|
- `no_beepers_present :: Karel -> Bool`<br>
|
||
|
Returns `True` if there is not beeper at the current intersection, `False` if there is a beeper at the current intersection
