项目描述

  1. 基本目的

    该库目的在于，提供一个强大的 基础调用库；将go的函数式统统变为链式调用

    目前实现了 Str ,Dict[k,t] , List[T] 三种结构，并提供了一系列 类似 python 和 rust 的便捷操作。

字符串常见操作

exmaple std 读取
package main

import "gitee.com/dark.H/go-utils/s"

func main() {
	s.Str("input some:").Println()
	s.Str("user name:").AsInput().Println("user name:")
	s.Str("password:").AsInput().Println("Password:")

}
exmaple 字符串操作

提取字符串

package main

import (
	"fmt"
	"os"

	"gitee.com/dark.H/go-utils/s"
)

var (
	w  = `this is a str test !!!!`
	w2 = `hell otis "sdsfd" asdfdsagdsa`
	w3 = "` asdfhaewg \" asdf 'fasfs `   asdfd"
)

func main() {

	s.Str(" hello ").ANSIStyle(s.FgGreen, s.ANSI_STYLE_UNDERLINE).ANSISelected().Println()
	raw := s.Str("@ex.go").ParseFileContent()
	u, _ := os.UserHomeDir()
	fmt.Println(u)

	raw.Extract("\nimport", ")\n").MapWith(func(i int, item s.EStr) any {
		// return item.ANSIBold().ANSIUnderline().ANSIBlue()
		raw[item.Start:item.End].ANSIGreen().Println()

		return s.Str("{{IMPORT AREA}}").ANSISelected()
	}).Each(func(key s.Str, item2 any) {
		raw = raw.Replace(key.String(), item2.(s.Str).String())

		// raw.StatusBar("show---")
		// time.Sleep(1 * time.Second)

	})
	raw.ExtractQuote().Each(func(i int, item s.EStr) {
		raw[item.Start:item.End].ANSIYellow().Println()
	})
}


package main

import (
	"fmt"

	"gitee.com/dark.H/go-utils/s"
)

func main() {
	raw := s.Str("@../extra_test/ex.go").ParseFileContent()
	// raw.ANSIGreen().Println()
	fmt.Println("--------- sub str test ------------")
	raw.SubStr(s.AFTER, "var").ExtractQuote().Each(func(i int, item s.EStr) {
		item.ANSIGreen().Println()
	})

	raw.SubStr(s.FROM, "{", s.TO, s.LAST, "}").ANSIYellow().Println().ExtractQuote().Each(func(i int, item s.EStr) {
		item.ANSIGreen().Println()
	})

	fmt.Println("------ edit test ---------------")

	raw.Edit(s.IN, "var (\n", ")", func(ex s.EStr) s.Str {
		return ex.Println().Insert("[test]", s.AFTER, "var (\n").Insert("[test-end]", ")")
	}).Println("[+ one]:").Edit(s.IN, "[test]", "[test-end]", func(e s.EStr) s.Str {
		return e.ANSIGreen().ANSIUnderline()
	}).Println("\n------------- sep ----------------- \n")
}
exmaple 字符串-文件操作(打开/ls/验证存在)
package main

import (
	"os/exec"

	"gitee.com/dark.H/go-utils/s"
)

func main() {
	p := s.Str(os.Args[1])
	p.FileList().Each(func(i int, item s.Str) {
		item.ANSIBlink().ANSIGreen().StatusBar("now in " + p.String())
		time.Sleep(1 * time.Second)
	})
	p2 := s.Str("asfsaf")
	p2.FileList()
	s.IfErrWillFatal()
	cmd := exec.Command("cmd.exe", "/c", "whoami")
	cmd.Output()
}
ini 配置文件的解析
[exmaple ini 配置文件的解析](https://gitee.com/dark.H/go-utils/blob/master/example/ini_decode/ini.go)

package main

import (
	"fmt"

	"gitee.com/dark.H/go-utils/s"
)

type S2 struct {
	Server string `ini:"server" default:"localhost:1080"`
	Name   string `ini:"name" default:"no name"`
	Pwd    string `ini:"pwd"`
	Port   int    `ini:"port" def:"80"`
	Can    bool   `ini:"can"`
}

func main1() {

	mp := s.Str("@ini.conf").ParseFileContent().ParseAsIniArg()
	c2 := new(S2)
	mp.DecodeAsStruct(c2)
	s.PrintlnStrcut(c2)

}

func main2() {
	c := &S2{
		Server: "115.23.asf.assf",
		Pwd:    "sdf",
	}
	s.ArgsFromINIStruct(c)

	s.PrintlnStrcut(c)
	if c.Can {
		fmt.Println(c.Name, c.Server, c.Port)

	}
}

或者 exmaple ini 配置文件的解析2

package main

import (
	"flag"
	"fmt"
	"log"

	"gitee.com/dark.H/go-utils/s"
)

func main() {
	line := ""
	line2 := ""
	line3 := false
	flag.StringVar(&line, "s", "one", "helo its")
	flag.StringVar(&line2, "s2", "tw", "helo its")
	flag.BoolVar(&line3, "s3", false, "helo its")
	s.Args()
	fmt.Println("s2=", line2)

	fmt.Println("s3=", line3)

	fmt.Println("s=", line)

	c2 := s.Dict[s.Str, any]{
		"hello":    "asfasgadg",
		"we":       "adsgadsgdddd",
		"ssss":     "can you see",
		"this-num": 12521,
		"sub": s.Dict[s.Str, any]{
			"sub-key": "key in second",
			"sub-num": 2,
		},
	}
	res, err := c2.AsStr(`{key} = {val} `, "\n", "[{key}]\n")
	if err != nil {
		log.Fatal(err)
	}
	fmt.Println("\n\n[base]\n" + res)

	d := s.FromIni(s.Str("@./test.ini").ParseFileContent())
	fmt.Println(d.Json())
}

ansi code 控制，包括了颜色， 进度条等功能：

[exmaple sub str](https://gitee.com/dark.H/go-utils/blob/master/example/ansi_control/control.go)
进度条
package main

import (
	"fmt"
	"time"

	"gitee.com/dark.H/go-utils/s"
)

func main() {

	raw := s.Str("@control.go").ParseFileContent()
	ls := raw.Split("\n")
	ls.Each(func(i int, item s.Str) {
		p := i * 100 / ls.Len()
		fmt.Println("line : ", item)
		s.ProgressShow(p, "show line:"+fmt.Sprint(i))
		time.Sleep(1 * time.Second)
	})
}

字节解析为 （自动将 Big5/utf16/gbk 转换为-> utf8 )


package main

import (
	"gitee.com/dark.H/go-utils/s"
)


func main(){
	someUtf16Bytes := []byte{......}
	str1,err := s.AutoDecode(someUtf16Bytes)
	str1.ANSIGreen().Println()
}

字符串作为cmd解析 (实现expect/完全交互)

[exmaple shell/cmd](https://gitee.com/dark.H/go-utils/blob/master/example/cmd/cmdmain.go)

package main

import "gitee.com/dark.H/go-utils/s"

func main() {

	// normal test
	// s.Str("whoami").AsCmd().Cd("..").Cd("~/Desktop").Exec("dir").Outputs().Each(func(i int, item s.Str) {
	// 	item.ANSIBlink().Println("[", i, "]: ")
	// })

	// err test
	// s.Str("git -h").AsCmd().Output().ANSICyan().ANSIStrike().Println()

	// expect test
	s.Str("ls .").AsCmd("..").Cd("stdin_input").Exec("stdin_input.exe",
		s.CSTR_EXPECT, "name:$", s.CSTR_TYPE, "[test username]\n",
		s.CSTR_EXPECT, "password:$", s.CSTR_TYPE, "[test passwprd]\n",
	).Output().ANSIBlink().Println()
	// interact test
	// s.Str("git add -A").AsCmd().Exec("git commit ", s.CSTR_INTERACT).Exec("git push origin master").Output().ANSIUnderline().ANSICyan().ANSIBold().Println()

}
字符串作为命令后台执行且，支持延迟执行

exmaple shell/cmd

package main

import (
	"fmt"
	"time"

	"gitee.com/dark.H/go-utils/s"
)

func main() {
	now := time.Now()
	c := s.List[s.Str]{}
	c.Push("test").Push("test2").Each(func(i int, item s.Str) {
		item.Println()
	})
	// s.Str("echo \"$(date) : $(whoami) \"  > /tmp/test.log").AsCmd().Delay(10).Run()

	// 延时执行
	s.Str("whoami > test.log").AsCmd().Delay(6).RunDaemon()

	//  延时执行删除自身的命令
	s.Str("").AsCmd().DelSelf(7)
	fmt.Println("end : ", time.Since(now))
}

字符串转 Bytes ，且支持流密钥加解密

exmaple bytes/str encrypt

package main

import (
	"fmt"
	"strconv"
	"time"

	"gitee.com/dark.H/go-utils/s"
)

func main() {
	init := byte(0b11011100)
	out := byte(0)

	c := strconv.FormatInt(int64(init), 2)
	c3 := s.Str(c[0]).ANSIGreen().A(c[1:4]).A(s.Str(c[4:7]).ANSIGreen().A(s.Str(c[7])))

	fmt.Println(" ---- test small m-sequence ----")
	fmt.Printf("%2d : %s | %d \n", -1, c3, out)
	for i := 0; i < 44; i++ {
		init = s.ByteMSeq(init)
		c := strconv.FormatInt(int64(init), 2)
		for len(c) < 8 {
			c = "0" + c
		}
		c3 := s.Str(c[0]).ANSIGreen().A(c[1:4]).A(s.Str(c[4:7]).ANSIGreen().A(s.Str(c[7])))
		fmt.Printf("%2d : %s | %d \n", i, c3, out)
	}
	fmt.Println(" ---- test encyrpt and decrypted ----")

	test := s.Str(`
	Sonnet 18  
		--- by sharkspear
Shall I compare thee to a summer's day?
Thou art more lovely and more temperate:
Rough winds do shake the darling buds of May,
And summer's lease hath all too short a date:
Sometime too hot the eye of heaven shines,
And often is his gold complexion dimm'd;
And every fair from fair sometime declines,
By chance or nature's changing course untrimm'd
But thy eternal summer shall not fade
Nor lose possession of that fair thou owest;
Nor shall Death brag thou wander'st in his shade,
When in eternal lines to time thou growest:
So long as men can breathe or eyes can see,
So long lives this and this gives life to thee.`)
	fmt.Println(test.Words())
	test = test.ANSIRandomBeautiful()
	println("raw   :", test)
	println("\nlen   :", len(test))
	key := s.Bytes("key!")
	start := time.Now()
	enc := s.Bytes(test).HXor(key)
	used := time.Since(start)
	println("\nencryed :", enc)
	s.Str("used:" + used.String()).ANSIYellow().ANSIBold().Println()
	start = time.Now()
	dec := enc.HXor(key)
	used = time.Since(start)
	decs := dec.Decode()
	decs.Print("decypt: ")
	println("\nlen   :", len(decs))

	s.Str("used:" + used.String()).ANSIYellow().ANSIBold().Println()

	fmt.Println(" ---- test hex encrypt ----")
	raw := s.Str("C:\\windows\\system32\\cmd.exe").Println("raw:")
	en := raw.HXorHex(string(key))
	en.Println()
	en.HXorHex(string(key)).Println("decry:")
	s.Str("288882f38f858987a96da29d94e2db6b936ab86ccc98bccdeff768").HXorHex("key!").Println()
}

扩展解析 os.Args

该库实现了golang的 flag <-> ini 文件 <-> Dict[k,t] <-> ini Str 等非常有用的参数和配置生成及转换
具体参见

package main

import (
	"fmt"

	"gitee.com/dark.H/go-utils/s"
)

type S2 struct {
	Server string `ini:"server" default:"localhost:1080"`
	Name   string `ini:"name" default:"no name"`
	Pwd    string `ini:"pwd"`
	Port   int    `ini:"port" def:"80"`
	Can    bool   `ini:"can"`
}

func main1() {

	mp := s.Str("@ini.conf").ParseFileContent().ParseAsIniArg()
	c2 := new(S2)
	mp.DecodeAsStruct(c2)
	s.PrintlnStrcut(c2)

}

func main2() {
	c := &S2{
		Server: "115.23.asf.assf",
		Pwd:    "sdf",
	}
	s.ArgsFromINIStruct(c)

	s.PrintlnStrcut(c)
	if c.Can {
		fmt.Println(c.Name, c.Server, c.Port)

	}
}
