我试图在python中执行一个预提交git钩子来检查文件是否有长度小于80个字符的行。但是我得到一个没有这样的文件/目录错误。我在Fedora上设置了＃！usr / bin / python.help，谢谢
I am trying to execute a pre commit git hook in python to check if files have line lengths less than 80 chars. However i get a no such file/directory error. i am on fedora and have set the #!usr/bin/python.help would be appreciated
#!/usr/bin/env python
#-*- mode: python -*-
from subprocess import Popen, PIPE
import sys
def run(command):
p = Popen(command.split(), stdout=PIPE, stderr=PIPE)
p.wait()
return p.returncode, p.stdout.read().strip().split(), p.stderr.read()
def precommit():
_, files_modified, _= run("git diff-index --name-only HEAD")
i=1
for fname in files_modified:
file = open(fname)
while i==1:
line = file.readline()
if not line:
break
elif len(line)>80:
print("Commit failed: Line greater than 80 characters")
return 1
return 0
sys.exit(precommit())
推荐答案
您的预先提交文件在其中有额外的回车。如果您在Windows中编辑文件并将该文件复制到Linux计算机上，则会发生这种情况。
Your pre-commit file has extraneous carriage returns in it. This can happen if you edit the file in Windows and copy the file to a Linux computer.
请尝试以下命令：
Try these commands:
cp .git/hooks/pre-commit /tmp/pre-commit
tr -d '\r' < /tmp/pre-commit > .git/hooks/pre-commit
然后重新运行你的 git 命令。
And then rerun your git command.
