我是否可以调用一个命令来计算Git存储库中特定作者更改的行数?我知道一定有方法来计算提交的数量,因为Github为他们的影响图这样做。
当前回答
我对上面的一个简短的回答作了修改,但这不足以满足我的需要。我需要能够对提交的行和最终代码中的行进行分类。我还想按文件进行细分。这段代码不递归,它只返回单个目录的结果,但如果有人想进一步了解,这是一个很好的开始。复制并粘贴到文件中并使其可执行或使用Perl运行。

对于windows用户,可以使用以下批处理脚本计算指定作者添加/删除的行数
@echo off
set added=0
set removed=0
for /f "tokens=1-3 delims= " %%A in ('git log --pretty^=tformat: --numstat --author^=%1') do call :Count %%A %%B %%C
@echo added=%added%
@echo removed=%removed%
goto :eof
:Count
if NOT "%1" == "-" set /a added=%added% + %1
if NOT "%2" == "-" set /a removed=%removed% + %2
goto :eof

为了防止有人想要查看他们代码库中每个用户的统计数据,我的几个同事最近想出了这样一个可怕的句子:
git log --shortstat --pretty="%cE" | sed 's/\(.*\)@.*/\1/' | grep -v "^$" | awk 'BEGIN { line=""; } !/^ / { if (line=="" || !match(line, $0)) {line = $0 "," line }} /^ / { print line " # " $0; line=""}' | sort | sed -E 's/# //;s/ files? changed,//;s/([0-9]+) ([0-9]+ deletion)/\1 0 insertions\(+\), \2/;s/\(\+\)$/\(\+\), 0 deletions\(-\)/;s/insertions?\(\+\), //;s/ deletions?\(-\)//' | awk 'BEGIN {name=""; files=0; insertions=0; deletions=0;} {if ($1 != name && name != "") { print name ": " files " files changed, " insertions " insertions(+), " deletions " deletions(-), " insertions-deletions " net"; files=0; insertions=0; deletions=0; name=$1; } name=$1; files+=$2; insertions+=$3; deletions+=$4} END {print name ": " files " files changed, " insertions " insertions(+), " deletions " deletions(-), " insertions-deletions " net";}'
(需要几分钟来处理我们的回购,其中有大约10-15k次提交。)
使用以下方法将日志保存到文件:
git log --author="<authorname>" --oneline --shortstat > logs.txt
对于Python爱好者:
with open(r".\logs.txt", "r", encoding="utf8") as f:
files = insertions = deletions = 0
for line in f:
if ' changed' in line:
line = line.strip()
spl = line.split(', ')
if len(spl) > 0:
files += int(spl[0].split(' ')[0])
if len(spl) > 1:
insertions += int(spl[1].split(' ')[0])
if len(spl) > 2:
deletions += int(spl[2].split(' ')[0])
print(str(files).ljust(10) + ' files changed')
print(str(insertions).ljust(10) + ' insertions')
print(str(deletions).ljust(10) + ' deletions')
你的输出是这样的:
225 files changed
6751 insertions
1379 deletions
你想责怪Git。
有一个——show-stats选项来打印一些统计数据。
除了Charles Bailey的回答之外,您可能还想在命令中添加-C参数。否则,即使文件内容没有被修改,文件重命名也会被视为大量的添加和删除(与文件的行数一样多)。
为了说明,当使用git log——oneline——shortstat命令时,这里有一个从我的一个项目中移动的大量文件的提交:
9052459 Reorganized project structure
43 files changed, 1049 insertions(+), 1000 deletions(-)
这里使用git log——oneline——shortstat -C命令来检测文件的复制和重命名:
9052459 Reorganized project structure
27 files changed, 134 insertions(+), 85 deletions(-)
在我看来,后者给出了一个人对项目有多大影响的更现实的观点,因为重命名一个文件比从头开始写文件要小得多。
