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())
