这是我在终端上执行 diffstat 时的输出。将数字 133 和 85 放入 CSV 文件的两列中的最佳方法是什么？谢谢。

README.md  |   88 +++++++++++++++++++++--------------------
home.html  |only
index.html |  130 ++++++++++++++++++++++++++++++++++++++++---------------------
libraries  |only
4 files changed, 133 insertions(+), 85 deletions(-)

假设您将差异写入文件diff.txt，如下所示：

README.md  |   88 +++++++++++++++++++++--------------------
home.html  |only
index.html |  130 ++++++++++++++++++++++++++++++++++++++++---------------------
libraries  |only
4 files changed, 133 insertions(+), 85 deletions(-)

并且有一个带有这些标题的.csv 文件：

insertions,deletions

那么这可以工作：

import re, csv

s = None

with open("diff.txt", mode="r") as diff_file:
    s = diff_file.readlines().pop()

regex = r"(?P<insertions>\d*) insertions\(\+\), (?P<deletions>\d*) deletions.*"
pattern = re.compile(regex)

match = pattern.search(s)

with open("diffs.csv", mode="a", newline="") as diffs_csv:
    fieldnames = ['insertions', 'deletions']
    writer = csv.DictWriter(diffs_csv, fieldnames=fieldnames)
    writer.writerow(match.groupdict())

这是我机器上的：

➜  diffstat ls
diffs.csv  diff.txt  main.py
➜  diffstat cat diffs.csv
insertions,deletions
➜  diffstat cat diff.txt
README.md  |   88 +++++++++++++++++++++--------------------
home.html  |only
index.html |  130 ++++++++++++++++++++++++++++++++++++++++---------------------
libraries  |only
4 files changed, 133 insertions(+), 85 deletions(-)
➜  diffstat python main.py
➜  diffstat cat diffs.csv
insertions,deletions
133,85

您可以创建diff.txt 文件并像这样运行脚本：

git diff --stat > diff.txt & python main.py

我喜欢你的正则表达式。谢谢！
