I’ve been readying through the Clean Code book by Robert C. Martin. I am only a chapter or two into the book and I feel like my code is becoming much more manageable and easier to ready. Method length was probably my biggest offender. I also used to comment a lot in code but now I am writing more self describing methods and variables so I don’t need to comment as much.
I saw a squirrel this morning and it did the usual thing of running to the nearest tree. For whatever reason I thought it would be an interesting exercise to write some pseudo-code about an event they would handle; here it goes.
1: protected void OnHumanSpotted(object sender, EventArgs e)
2: {
3: List<Trees> localTrees = GetSurroundingTrees();
4:
5: Tree closestClimbableTree = GetSafestTreeToClimb(localTrees);
6:
7: if (closestClimbableTree != null)
8: {
9: Climb(closestClimbableTree);
10: }
11: else
12: {
13: FleeOnFoot();
14: }
15: }
I like how you don’t need to know the implementation of any of the methods, the intent of the code is communicated through the method names. I am sure this could be improved even more by encapsulating the methods even more but it works for this simple example.
Cheers!
