命令行生成工具

格式

# 命令解析
$ [command] <option>

# 简单选项
$ <option>

#
# -- 与 - 的区别，参考Linux常用命令格式
--fix	# 选项全拼
-fix    # 选择简写，等同于 -f -i -x

#
# 命令行数据格式
--name='Joshua Conero'
--name 'Joshua Conero'

# only-option 作为无值选项
--only-option --last-name Conero
# 短标签映射关系（需要建立映射关系）
# -N,--name
# -O,--only-option
# 数组型参数
--persons Conero Jahn Lile Any --prex

# 实现属性严格检查开关(此时需要注册所有选择)

数据格式

支持的基本类型如下：

  • 数字 number
    • 整形 int64
    • 浮点型 float64
  • 布尔类型 bool
  • 字符串 string
# 字符串
# string
$ 'the data string.'	# the data string.
$ "the data string."	# the data string.

# 数字类型，默认最长的数字类型
# int64, float64
$ 8						# int64
$ 8.88					# float64

# bool 类型(不区分大小写)
$ True
$ true

# 数组
# 分割符号(separator)  默认","
$ 'a','b','c','d'		# array [a, b, c, d]
# "," 分割
$ --separator-comma 
$ -spt-c
$ --array a1 a3 a4 a5
$ --array {a1,a3,a4,a5}
特殊数据支持

待实现

#
# 解析 json 字符串、支持json字符串、文件或地址
$ --load-json,--LJ <json-string>
$ --load-json-file,--LJF <json-filename>
$ --load-json-url,--LJU <json-url-url>

#
# url 地址数据形式支持
$ --load-url,--LU <url-字符串数据>
$ --load-url-file,--LUF <url-filename>
$ --load-url-url,--LUU <url-url-url>

#
# 脚本支持
$ --script <file-name> 只是脚本解析
解析算法实现
python
def option_parse(args, strict_option_list=None):
    '''
    见: _example/design/option-parse/option-parse.py
    '''
    pass

教程

路由状态分为：命令匹配成功 、空命令状态、自定义函数路由成功状态。

命令行程序可实现 对象式 和 函数式， 同时持：对象式/函数式混合风格

对象式
package main

import (
	"fmt"
	"gitee.com/conero/uymas/bin"
)
// 命令 test
type Test struct {
	bin.Command
}
// 项目初始化
func (a *Test) Init ()  {
    // 重写方法时必先系统父结构体方法[!!]
    a.Command.Init()
    
    // todo ....
}
// 运行，执行内二级命令分发
func (a *Test) Run ()  {
	fmt.Println("ffff.")
}

// 命令 yang
type Yang struct {
	bin.Command
}


func main() {
	//router := &bin.Router{}
	//bin.Register("test", &Test{})
	//bin.Register("yang", &Yang{})
	//bin.Adapter(router)
	bin.RegisterApps(map[string]interface{}{
		"test": &Test{},
		"yang": &Yang{},
	})
	bin.Run()
}
函数式
package main

import (
	"gitee.com/conero/uymas/bin"
)


func main() {
	// 项目注册
	bin.RegisterFunc("name", func() {
		fmt.Println(" conero/uymas/bin example with Base.")
	})

	// 未知命令
	bin.UnfindFunc(func(cmd string) {
		fmt.Println(cmd + "unfind（functional）")
	})

	// 空函数
	bin.EmptyFunc(func() {
		fmt.Println("empty（functional）")
	})

	bin.Run()
}

数据加载

支持多种数据加载

# 大量数据加载实现
./uymas-bin.exe --load-json '{"json":"json 字符串"}' --load-json='{"json2": "方法二"}'
./uymas-bin.exe --load-url-style 'key=value&k2=v2&k3=v3'
./uymas-bin.exe --load-session-style 'key:value; k2:v2; k3:v3;'

# 不同数据加载
# 长选项
--key 'value'
--key='value'
--command-style

# 单选项
-P 'value'
-C
json
url-style
session-style
struct 设置到命令路由

定义Struct直接映射为命令路由注册

type CMD struct {
	Title    string   //标题
	Command  string   //命令行
	Alias    []string //别名
	Describe string   //描述

	HelpMessage string           //帮助信息
	HelpCall    func(cc *CliCmd) //帮助信息回调

	//回调，可以默认为当前本身
	Todo    func(cc *CliCmd) //命令回调
	TodoApp interface{}      //命令绑定信息
}
命令
// 命令描述
