如何使用gitpython做最后一次提交的当前提交的git diff？

我试图把握Ø模块gitpython，如何使用gitpython做最后一次提交的当前提交的git diff？

hcommit = repo.head.commit 
tdiff = hcommit.diff('HEAD~1')

但tdiff = hcommit.diff('HEAD^ HEAD')不起作用！ ('HEAD~ HEAD')。，

我想获得差异输出！

我承认从未使用的gitpython代码，但它似乎很明显，如果hcommit是'repo.head.commit'，它被绑定到*特殊*提交，因此'hcommit.diff'的意思是“不同于其他东西”。为了得到两个任意提交的差异，你必须选择其他的起点。 – torek

我想出了如何使用gitPython获取git diff。

import git 
repo = git.Repo("path/of/repo/") 

# the below gives us all commits 
repo.commits() 

# take the first and last commit 

a_commit = repo.commits()[0] 
b_commit = repo.commits()[1] 

# now get the diff 
repo.diff(a_commit,b_commit)

瞧！

我得到'AttributeError：'Repo'对象没有属性'diff''，而'Repo.diff'没有在[API doc]中提到（https://gitpython.readthedocs.io/en/stable/reference。 HTML）。这个答案是否需要更新？ – phihag

import git 

repo = git.Repo('repo_path') 
commits_list = list(repo.iter_commits()) 

# --- To compare the current HEAD against the bare init commit 
a_commit = commits_list[0] 
b_commit = commits_list[-1] 

a_commit.diff(b_commit)

这将返回提交的diff对象。还有其他方法可以实现这一点。例如（这是复制/ http://gitpython.readthedocs.io/en/stable/tutorial.html#obtaining-diff-information粘贴）：

```

hcommit = repo.head.commit 
    hcommit.diff()     # diff tree against index 
    hcommit.diff('HEAD~1')   # diff tree against previous tree 
    hcommit.diff(None)    # diff tree against working tree 

    index = repo.index 
    index.diff()     # diff index against itself yielding empty diff 
    index.diff(None)    # diff index against working copy 
    index.diff('HEAD')    # diff index against current HEAD tree

```

，为妥善解决（不使用Git命令回调），您必须使用create_patch选项。

比较当前指数与以前的承诺：

diff_as_patch = repo.index.diff(repo.commit('HEAD~1'), create_patch=True) 
print(diff_as_patch)

要获得差异的内容：

import git 
repo = git.Repo("path/of/repo/") 

# define a new git object of the desired repo 
gitt = repo.git 
diff_st = gitt.diff("commitID_A", "commitID_B")
