预提交钩子git错误

Question

我试图在python中执行pre commit git hook来检查文件的行长度是否小于80个字符.但是我得到一个没有这样的文件/目录错误.我在fedora上设置#!usr/bin/python.help将不胜感激

#!/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())

Answer 1

您的预提交文件中包含无关的回车符.如果在Windows中编辑文件并将文件复制到Linux计算机,则会发生这种情况.

试试这些命令:

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.

Answer 2

删除 '\r' 的最简单方法是：

dos2unix .git/hooks/pre-commit
