【Python】打包click模块写的模块

为什么要打包

• 可以在任意位置运行模块和包
• 不用输入python xxx.py，输入软件名称就可以直接运行

怎么打包

• 使用setuptools

  打包hello.py

参考：Setuptools Integration — Click Documentation (7.x)

1. 准备工作

   mkdir hello & cd hello
   touch setup.py hello.py

1. setup.py内容 ```python from setuptools import setup

setup( name=’hello’, version=’0.1’, py_modules=[‘hello’], install_requires=[ ‘Click’, ], entry_points=’’’ [console_scripts] hello=hello:cli ‘’’, )

3.  hello.py内容 
```python
import click
@click.command()
@click.option('-s', '--string', default='World',help="This is the thing that is greeted")
@click.option('-n', '--number', default=1, help="This is the number of times to greet")
@click.argument('output', type=click.File('w'), default='-',required=False)
def cli(string,number,output):
    """This scripts greets you."""
    for x in range(number):
        click.echo(f'Hello {string}', file=output)

1. 然后运行下面这段代码，以把该脚本添加到环境

   pip install --editable .

1. 现在直接输入hello就可以运行了 ```shell $ hello —help Usage: hello [OPTIONS] [OUTPUT]

   This scripts greets you.

Options: -s, —string TEXT This is the thing that is greeted -n, —number INTEGER This is the number of times to greet —help Show this message and exit.

$ hello —string “Achuan” —number 3 ./output.txt

## 打包pygit
尝试用python实现git操作
setup.py内容
```python
from setuptools import setup
setup(
    name='pygit',
    version='0.1',
    py_modules=['pygit'],
    install_requires=[
        'Click',
    ],
    entry_points='''
        [console_scripts]
        pygit=pygit:cli
    ''',
)

pygit.py内容

import os
import click
from git.cmd import Git
import datetime
git = Git(os.getcwd())
@click.group()
def cli():
    """
    git 命令行
    """
    pass
@cli.command()
def lazy():
    """
    直接提交 add . commit Today
    """
    # git add
    cmd = ['git', 'add','.']
    output = git.execute(cmd)
    # git commit
    msg = ":memo:"+str(datetime.date.today())
    cmd = ['git', 'commit', '-m', msg]
    output = git.execute(cmd)
    # git push
    cmd = ['git', 'push']
    output = git.execute(cmd)
    click.secho('done',fg='green')
@cli.command()
def status():
    """
    处理 status 命令
    """
    cmd = ['git', 'status']
    output = git.execute(cmd)
    click.echo(output)
@cli.command()
@click.argument('pathspecs', nargs=-1, metavar='[PATHSPEC]...')
def add(pathspecs):
    """
    处理 add 命令
    """
    cmd = ['git', 'add'] + list(pathspecs)
    output = git.execute(cmd)
    click.echo(output)
@cli.command()
@click.option('-m', 'msg')
def commit(msg):
    """
    处理 -m <msg> 命令
    """
    cmd = ['git', 'commit', '-m', msg]
    output = git.execute(cmd)
    click.echo(output)
@cli.command()
def push():
    """
    处理 push 命令
    """
    cmd = ['git', 'push']
    output = git.execute(cmd)
    click.echo(output)
if __name__ == '__main__':
    cli()

之后就能pygit lazy快速提交当日代码了

$ pygit --help
Usage: pygit [OPTIONS] COMMAND [ARGS]...
  git 命令行
Options:
  --help  Show this message and exit.
Commands:
  add     处理 add 命令
  commit  处理 -m <msg> 命令
  lazy    直接提交 add .
  push    处理 push 命令
  status  处理 status 命令
$pygit lazy
