介绍

使用zshell可快速构建命令行应用

安装

pip安装

pip install -i https://pypi.org/project pyzshell

开始

编写第一个zshell应用

创建helloworld.py文件导入模块

import zshell

创建一个应用

app=zshell.App()

编写命令

@app.shell
def helloworld():
    return 'Hello World'

运行应用

app.run()

完整代码

#coding=utf-8
import zshell

app=zshell.App()

@app.shell
def helloworld():
    return 'Hello World'

if __name__ == '__main__':
    app.run()

运行helloworld.py文件

python helloworld.py
zshell:>>helloworld
Hello World

交互式运行

python 文件.py

python helloworld.py
zshell:>>helloworld
Hello World

非交互式运行

python 文件.py 命令参数

python helloworld.py helloworld
Hello World

参数

变长参数

新建add函数，函数参数为元组变长参数，参数名必须是args

@app.shell
def add(*args):
    num=0
    for i in args:
        num+=i
    return num

输入add 1 2 3调用add命令,将参数值1，2，3相加得出结果为6

zshell:>>add 1 2 3
6
zshell:>>add 1 2 3 4
10

新建add2函数，函数参数为字典变长参数，参数名必须是kwargs

@app.shell
def add2(**kwargs):
    return kwargs['a']+kwargs['b']

输入add2 -a 1 -b 1调用add2命令,相加得出结果为2

参数仅支持英文或以-、–开头的英文，-、–开头的参数zshell会自动去掉-、–符号

zshell:>>add2 -a 1 -b 1
2
zshell:>>add2 -a 1 -b 1 -c 1
2

非变长参数

新建add3函数，函数参数随意

@app.shell
def add3(a=0,b=0,c=0):
    return a+b+c

输入add3 1 2 3调用add3命令,相加得出结果为6

zshell:>>add3 1 2 3
6
zshell:>>add3 1 2 3 4
6
zshell:>>add3 1
1

@app.shell详解

将函数添加到zshell命令

参数	说明	类型	默认
name	命令名使用\|可分隔多个命令名	string	函数名
desc	命令描述	string	“”
args	命令参数	list	[]
