RBTLIB v0.3 Update (Part 2)
—A client-side library for Review Board.
In RBTLIB v0.3 Update (Part 1)
I discussed some plans for posting review requests to a Review Board instance using RBTLIB
. During the development I added a complexity measure to the project. I was intrigued by how complexity measures were used in a talk by Sandi Metz
. Sandi's talk is on Ruby. I'm using Python.
I found two Python modules: radon
that compute cyclomatic complexity
. Radon computes several measures and xenon provides a way to add complexity measures to a continuous integration.
To measure the entire project, including test code from the project's root directory:
radon cc -e "ven/*" -as .
The core abstraction in RBTLIB at this point is still the Composite design pattern.
This component has the highest complexity:
M 41:4 Composite.href_component - B (6)
M 63:4 Composite.component - B (6)
C 31:0 Composite - A (4)
M 53:4 Composite.list_component - A (4)
M 34:4 Composite.__init__ - A (1)
From the radon documents:
M - Module
C - Class
A - low - simple block
B - low - well structured and stable block
Overall complexity of the project thus far:
72 blocks (classes, functions, methods) analyzed.
Average complexity: A (1.88888888889)
So far, complexity doesn't appear to be a problem.
