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。

这是一个很好的工具，可以一次性获得所有作者的计数，包括提交和修改文件的计数:
sudo apt-get install ruby-dev
sudo gem install git_fame
cd /path/to/gitdir && git fame
https://github.com/casperdcl/git-fame上也有Python版本(@fracz提到过):
sudo apt-get install python-pip python-dev build-essential
pip install --user git-fame
cd /path/to/gitdir && git fame
样例输出:
Total number of files: 2,053
Total number of lines: 63,132
Total number of commits: 4,330

但是要注意的是:正如Jared在评论中提到的，在一个非常大的存储库上做这件事将花费数小时。但考虑到它必须处理如此多的Git数据，不确定是否可以改进。
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。
我编写了这个Perl脚本来完成这项任务。
#!/usr/bin/env perl
use strict;
use warnings;
# save the args to pass to the git log command
my $ARGS = join(' ', @ARGV);
#get the repo slug
my $NAME = _get_repo_slug();
#get list of authors
my @authors = _get_authors();
my ($projectFiles, $projectInsertions, $projectDeletions) = (0,0,0);
#for each author
foreach my $author (@authors) {
my $command = qq{git log $ARGS --author="$author" --oneline --shortstat --no-merges};
my ($files, $insertions, $deletions) = (0,0,0);
my @lines = `$command`;
foreach my $line (@lines) {
if ($line =~ m/^\s(\d+)\s\w+\s\w+,\s(\d+)\s\w+\([\+|\-]\),\s(\d+)\s\w+\([\+|\-]\)$|^\s(\d+)\s\w+\s\w+,\s(\d+)\s\w+\(([\+|\-])\)$/) {
my $lineFiles = $1 ? $1 : $4;
my $lineInsertions = (defined $6 && $6 eq '+') ? $5 : (defined $2) ? $2 : 0;
my $lineDeletions = (defined $6 && $6 eq '-') ? $5 : (defined $3) ? $3 : 0;
$files += $lineFiles;
$insertions += $lineInsertions;
$deletions += $lineDeletions;
$projectFiles += $lineFiles;
$projectInsertions += $lineInsertions;
$projectDeletions += $lineDeletions;
}
}
if ($files || $insertions || $deletions) {
printf(
"%s,%s,%s,+%s,-%s,%s\n",
$NAME,
$author,
$files,
$insertions,
$deletions,
$insertions - $deletions
);
}
}
printf(
"%s,%s,%s,+%s,-%s,%s\n",
$NAME,
'PROJECT_TOTAL',
$projectFiles,
$projectInsertions,
$projectDeletions,
$projectInsertions - $projectDeletions
);
exit 0;
#get the remote.origin.url joins that last two pieces (project and repo folder)
#and removes any .git from the results.
sub _get_repo_slug {
my $get_remote_url = "git config --get remote.origin.url";
my $remote_url = `$get_remote_url`;
chomp $remote_url;
my @parts = split('/', $remote_url);
my $slug = join('-', @parts[-2..-1]);
$slug =~ s/\.git//;
return $slug;
}
sub _get_authors {
my $git_authors = 'git shortlog -s | cut -c8-';
my @authors = `$git_authors`;
chomp @authors;
return @authors;
}
我将其命名为git-line-changes-by-author，并放入/usr/local/bin。因为它保存在我的路径中，所以我可以在2020-01-01之后发出命令git line-changes-by-author—before 2018-12-31—以获得2019年的报告。举个例子。如果我拼错了名字，git会建议正确的拼写。
你可能想要调整_get_repo_slug子只包括remote.origin.url的最后一部分，因为我的回购保存为项目/回购，而你的可能不是。
下面是一个简短的一行代码，用于生成所有作者的统计信息。它比Dan在https://stackoverflow.com/a/20414465/1102119上的解决方案快得多(我的解决方案的时间复杂度是O(N)，而不是O(NM)，其中N是提交的数量，M是作者的数量)。
git log --no-merges --pretty=format:%an --numstat | awk '/./ && !author { author = $0; next } author { ins[author] += $1; del[author] += $2 } /^$/ { author = ""; next } END { for (a in ins) { printf "%10d %10d %10d %s\n", ins[a] - del[a], ins[a], del[a], a } }' | sort -rn
下面是一个快速ruby脚本，针对给定的日志查询汇总每个用户的影响。
例如rubinius:
Brian Ford: 4410668
Evan Phoenix: 1906343
Ryan Davis: 855674
Shane Becker: 242904
Alexander Kellett: 167600
Eric Hodel: 132986
Dirkjan Bussink: 113756
...
脚本:
#!/usr/bin/env ruby
impact = Hash.new(0)
IO.popen("git log --pretty=format:\"%an\" --shortstat #{ARGV.join(' ')}") do |f|
prev_line = ''
while line = f.gets
changes = /(\d+) insertions.*(\d+) deletions/.match(line)
if changes
impact[prev_line] += changes[1].to_i + changes[2].to_i
end
prev_line = line # Names are on a line of their own, just before the stats
end
end
impact.sort_by { |a,i| -i }.each do |author, impact|
puts "#{author.strip}: #{impact}"
end
