[JAVA] Discover the most yabe functions on github
Introduction
The other day, at work, I got excited with the story of "the most yabe function I repaired or wrote." Everyone talked a lot, but after all it was an overwhelming victory for the "command pattern main loop function (1500 lines)" I wrote. Why did you write such code?
So, today I will discover "the best function in the world" from github to heal my injured pride. In other words, "I'm going to see a Yabe function rather than a function I wrote."
Conclusion
- Seriously, there are two functions
- ** "cv :: against_cornerScore \
function in opencv repository (Complexity 1868) ** - ** "OpenTag function in SuiteCRM repository" (complexity 1509) **
- Focusing on the trends of each language ...
- ** There are many yabe functions in javascript **
- ** python / java / swift / ruby has many clean functions **
Method
What is a yabe function?
Here, the Yabe function is identified by the following procedure.
- Identify "functions with high cyclomatic complexity". Cyclomatic complexity was calculated using lizard.
- Really narrow down to Yabe functions Look inside and exclude test code or auto-generated code.
Determining the target repository
Using github-trending-api, Look for Yabe functions by picking out popular projects from the last month in the following languages:
- C
- C++
- Python
- Java
- JavaScript
- Swift
- Ruby
- PHP
- Scala
- Golang
- Lua
code
I don't do any tests cycro
result
1. Identify "functions with high cyclomatic complexity"
The top 10 functions with high complexity without considering the contents of the code are as follows.
| No | Complexity | Function name | Project name | Language name |
|---|---|---|---|---|
| 1 | 5505 | jo | node | javascript |
| 2 | 2013 | matchIcon | edex-ui | javascript |
| 3 | 2001 | foo | llvm-project | cpp |
| 4 | 1947 | *global* | node | javascript |
| 5 | 1868 | cv::agast_cornerScore<AgastFeatureDetector::AGAST_7_12s> | opencv | cpp |
| 6 | 1647 | int | kubernetes | go |
| 7 | 1532 | foo | llvm-project | cpp |
| 8 | 1509 | OpenTag | SuiteCRM | php |
| 9 | 1504 | foo | llvm-project | cpp |
| 10 | 1453 | iT | node | javascript |
2. Really narrow down to Yabe functions
If you actually look at the contents of the code ...
| No | Complexity | Function name | Project name | Language name | Remarks |
|---|---|---|---|---|---|
| 1 | 5505 | jo | node | javascript | Because it is obfuscated |
| 2 | 2013 | matchIcon | edex-ui | javascript | Just line up 2000 if statements |
| 3 | 2001 | foo | llvm-project | cpp | For testing&&Just line up 2000 |
| 4 | 1947 | *global* | node | javascript | Because it is obfuscated |
| 5 | 1868 | cv::agast_cornerScore<AgastFeatureDetector::AGAST_7_12s> | opencv | cpp | This guy is bad |
| 6 | 1647 | int | kubernetes | go | Code automatically generated by the parser generator |
| 7 | 1532 | foo | llvm-project | cpp | Test code |
| 8 | 1509 | OpenTag | SuiteCRM | php | This guy is bad |
| 9 | 1504 | foo | llvm-project | cpp | Test code |
| 10 | 1453 | iT | node | javascript | Because it is obfuscated |
Conclusion
As described in the remarks column, the following two are really yabe functions. See the actual code with your own eyes! (Too long to stretch)
| No | Complexity | Function name | Project name | Language name | Remarks |
|---|---|---|---|---|---|
| 5 | 1868 | cv::agast_cornerScore<AgastFeatureDetector::AGAST_7_12s> | opencv | cpp | This guy is bad |
| 8 | 1509 | OpenTag | SuiteCRM | php | This guy is bad |
Comparison of complexity between languages
I plotted the complexity distribution for each language.
Violin plot with outliers
Violin plot without outliers
Excluding values outside the range of mean ± 2 * standard deviation for each language, it is as follows.
Finally
Forgive me if I make a mistake ...
