Before the workshop you should have watched the lectures. Some workshops have pre-workshop tasks which are optional, but useful. Completing labs before workshops is also optional (but may be useful)!
This week's workshop will work slightly differently to previous weeks. This is because the content for this week is more gentle, and we want to give people time for thinking about the assignment.
We expect that we will split the class in half, with one tutor for each half of the class leading a discussion.
First, we will do a short code review. This will take the form of choosing an
christmas_tree), and having everyone pull up
their code. Much like in a pull-request, we will get students to swap
computers and leave comments on things they like, don't like, or have
questions about. Then, in a larger group, we will look through some of the
interesting code and have a group discussion.
Second, we will have a discussion on the theoretical answers given to questions in Week 2 and Week 3's exercises. This will be the main opportunity for tutors to give feedback on that theoretical work. If you cannot make this weeks workshop, you will still get marks for submitting the theoretical work, but you will not get feedback (unless you ask us seperately). If you can turn up, you will get detailed feedback on those answers.
After the first two parts of the workshop, we will split into small groups
where you can work on
directions_lib (which is provided as partially working
starter code). If you can get it working,
it will be useful for your assignment. Unlike other code, you may use this
code in your assignment even if somebody else in your group contributed to it
Directions lib implements three types:
CardinalDirection. Try and create a library which:
- Can add (including += ) Directions and Coordinates.
- Can create Directions from CardinalDirections.
- Can find if a Coordinate is within a rectange defined by two other Coordinates.
- Has documentation for every public type.
- Has at least one doctest for every public type.
- Has tests to check internal functionality. We suggest one test per method/function.
- Bonus: Does anything other features you think might be useful for the assignment.
- Bonus: Finds the distance between two points.
- Bonus: Implements scalar multiplication on Directions.
