我如何运行一个virtualenv python脚本作为git pre-commit钩子 [英] How can I run a virtualenv python script as a git pre-commit hook

问题描述

这是我的pre-commit脚本：

 ＃！/ bin / bash 
 for f in .git /hooks/pre-commit.d/*;如果[-x$ f]执行
;那么
 if！ $ F;那么
会回显不会改变你的改变！; 
出口1 
 fi 
 fi 
完成
  

pre-commit.d中的一个可执行文件是一个以脚本开头的python脚本（precommit-pylint.py）。

 ＃！/ usr / bin / env python 
 import pylint 
  

pylint安装在我的virtualenv中。我的问题是git运行预先提交pre prepending / usr / libexec / git-core：/ usr / bin 到 $ PATH ，所以即使我的virtualenv被激活， pre-commit.d / precommit-pylint.py 脚本也会与系统 / usr一起运行/ bin / python （而不是使用virtualenv python运行）。

我想要具有与不使用开发者兼容的钩子virtualenv中。有没有办法透明地使用virtualenv来运行我的python脚本（即，与使用他们的系统python的开发人员保持兼容）？ 解决方案

p>您可以在您的预提交脚本中检查$ VIRTUAL_ENV变量，并相应地将其前置到$ PATH中：

 ＃！ / bin / bash 
 
 if [-n $ VIRTUAL_ENV];那么
 PATH = $ VIRTUAL_ENV / bin：$ PATH 
 fi 
 
 for .git / hooks / pre-commit.d / *;如果[-x$ f]执行
;那么
 if！ $ F;那么
会回显不会改变你的改变！; 
出口1 
 fi 
 fi 
完成
  

This is my pre-commit script:

#!/bin/bash
for f in .git/hooks/pre-commit.d/*; do
    if [ -x "$f" ]; then
        if ! "$f"; then
            echo "DID NOT COMMIT YOUR CHANGES!";
            exit 1
        fi
    fi
done

One of the executables in pre-commit.d is a python script (pre-commit-pylint.py) that starts with:

#!/usr/bin/env python
import pylint

pylint is installed on my virtualenv. My problem is that git runs pre-commit prepending /usr/libexec/git-core:/usr/bin to $PATH, so even if my virtualenv is activated the pre-commit.d/pre-commit-pylint.py script runs with the system /usr/bin/python (instead of running with the virtualenv python).

I want to have hooks that are compatible for developers that are not using virtualenv. Is there any way to run my python script with virtualenv transparently (ie, staying compatible with developers that are using their system python)?

解决方案

You can check in your pre-commit script for the $VIRTUAL_ENV variable and prepend it to $PATH accordingly:

#!/bin/bash

if [ -n $VIRTUAL_ENV ]; then
    PATH=$VIRTUAL_ENV/bin:$PATH
fi

for f in .git/hooks/pre-commit.d/*; do
    if [ -x "$f" ]; then
        if ! "$f"; then
            echo "DID NOT COMMIT YOUR CHANGES!";
            exit 1
        fi
    fi
done
