raiden00pl commented on PR #16962:
URL: https://github.com/apache/nuttx/pull/16962#issuecomment-3244125446
> Is this possible to auto-generate this file contents based on git logs? I
mean by hand with some script in nuttx/tools/ for instance that later can be
used to update the file? For now it seems to be generated by hand?
I played around with vibe-coding for a moment and got this script:
```
import subprocess
import argparse
from collections import Counter
from pathlib import Path
def get_files():
"""Get list of all tracked files in repo."""
result = subprocess.run(
["git", "ls-files"],
stdout=subprocess.PIPE,
text=True,
check=True
)
return result.stdout.strip().split("\n")
def get_files_in_directory(directory):
"""Get list of tracked files inside a given directory."""
result = subprocess.run(
["git", "ls-files", directory],
stdout=subprocess.PIPE,
text=True,
check=True
)
return result.stdout.strip().split("\n")
def get_author_stats(file_path):
"""Return a Counter of authors by blamed lines in a file."""
result = subprocess.run(
["git", "blame", "--line-porcelain", file_path],
stdout=subprocess.PIPE,
text=True,
check=True
)
authors = []
for line in result.stdout.splitlines():
if line.startswith("author "):
author = line[len("author "):].strip()
authors.append(author)
return Counter(authors)
def print_top_authors(file_path, top_n):
"""Print top N authors for a file with counts and percentages."""
counter = get_author_stats(file_path)
if not counter:
return
total = sum(counter.values())
print(f"{file_path}:")
for author, count in counter.most_common(top_n):
percent = (count / total) * 100
print(f" {author} - {count} lines ({percent:.1f}%)")
def main():
parser = argparse.ArgumentParser(
description="Find the author(s) with the most blamed lines per file
in a Git repo."
)
parser.add_argument(
"path",
nargs="?",
help="Specific file or directory to check (if omitted, checks all
repo files)"
)
parser.add_argument(
"--top",
type=int,
default=1,
help="Show top N authors instead of just the top one (default: 1)"
)
args = parser.parse_args()
if args.path:
p = Path(args.path)
if p.is_file():
print_top_authors(str(p), args.top)
elif p.is_dir():
files = get_files_in_directory(str(p))
for f in files:
print_top_authors(f, args.top)
else:
print(f"Path not found in repo: {args.path}")
else:
files = get_files()
for f in files:
print_top_authors(f, args.top)
if __name__ == "__main__":
main()
```
It shows the primary contributor of a given file based on `git blame`.
Works on the entire repo, on directories within the repo or on single files.
You can also specify `--top N` options to see the top N authors.
