How can I graph the Lines of Code history for git repo?
提问by dbr
Basically I want to get the number of lines-of-code in the repository after each commit.
基本上我想在每次提交后获取存储库中的代码行数。
The only (really crappy) ways I have found is to use git filter-branchto run wc -l *, and a script that runs git reset --hardon each commit, then runs wc -l
我发现的唯一（非常糟糕的）方法是使用git filter-branchrun wc -l *，以及git reset --hard在每次提交时运行的脚本，然后运行wc -l
To make it a bit clearer, when the tool is run, it would output the lines of code of the very first commit, then the second and so on. This is what I want the tool to output (as an example):
为了更清楚一点，当工具运行时，它会输出第一次提交的代码行，然后是第二次，依此类推。这是我希望该工具输出的内容（例如）：
me@something:~/$ gitsloc --branch master
10
48
153
450
1734
1542
I've played around with the ruby 'git' library, but the closest I found was using the .lines()method on a diff, which seems like it should give the added lines (but does not: it returns 0 when you delete lines for example)
我玩过 ruby 'git' 库，但我发现最接近的是.lines()在差异上使用该方法，这似乎应该提供添加的行（但不会：例如，当您删除行时它返回 0）
require 'rubygems'
require 'git'
total = 0
g = Git.open(working_dir = '/Users/dbr/Desktop/code_projects/tvdb_api')
last = nil
g.log.each do |cur|
diff = g.diff(last, cur)
total = total + diff.lines
puts total
last = cur
end

You may get both added and removed lines with git log, like:
您可能会使用 git log 获得添加和删除的行，例如：
git log --shortstat --reverse --pretty=oneline
From this, you can write a similar script to the one you did using this info. In python:
由此，您可以编写与使用此信息所做的脚本类似的脚本。在蟒蛇中：
#!/usr/bin/python
"""
Display the per-commit size of the current git branch.
"""
import subprocess
import re
import sys
def main(argv):
git = subprocess.Popen(["git", "log", "--shortstat", "--reverse",
"--pretty=oneline"], stdout=subprocess.PIPE)
out, err = git.communicate()
total_files, total_insertions, total_deletions = 0, 0, 0
for line in out.split('\n'):
if not line: continue
if line[0] != ' ':
# This is a description line
hash, desc = line.split(" ", 1)
else:
# This is a stat line
data = re.findall(
' (\d+) files changed, (\d+) insertions\(\+\), (\d+) deletions\(-\)',
line)
files, insertions, deletions = ( int(x) for x in data[0] )
total_files += files
total_insertions += insertions
total_deletions += deletions
print "%s: %d files, %d lines" % (hash, total_files,
total_insertions - total_deletions)
if __name__ == '__main__':
sys.exit(main(sys.argv))

The first thing that jumps to mind is the possibility of your git history having a nonlinear history. You might have difficulty determining a sensible sequence of commits.
首先想到的是您的 git 历史可能具有非线性历史。您可能难以确定合理的提交顺序。
Having said that, it seems like you could keep a log of commit ids and the corresponding lines of code in that commit. In a post-commit hook, starting from the HEAD revision, work backwards (branching to multiple parents if necessary) until all paths reach a commit that you've already seen before. That should give you the total lines of code for each commit id.
话虽如此，您似乎可以在该提交中保留提交 ID 和相应代码行的日志。在提交后挂钩中，从 HEAD 修订版开始，向后工作（如有必要，分支到多个父级），直到所有路径都到达您之前已经见过的提交。这应该为您提供每个提交 ID 的总代码行数。
Does that help any? I have a feeling that I've misunderstood something about your question.
这有帮助吗？我有一种感觉，我误解了你的问题。
