ExportIt

What is this?

Just write your function, and you'll have a CLI tool-no need to worry about flags, figuring out their names, or creating a config struct to manage them. Simply focus on the function, and let me take care of the rest.

Usage

1. create your functions

func Curl(link string) (string, error) {
	res, err := http.Get(link)
	if err != nil {
		return "", err
	}
	defer res.Body.Close()
	data, err := io.ReadAll(res.Body)
	if err != nil {
		return "", err
	}
	return string(data), nil
}

func Cat(path string) (string, error) {
	data, err := os.ReadFile(path)
	if err != nil {
		return "", err
	}
	fmt.Println(string(data))
	return string(data), nil
}

2. use the tool

import (
	"fmt"
	"io"
	"net/http"
	"os"

	"github.com/nasoooor29/ExportIT"
)

func main() {
	ExportIT.ExecCli(
		"appName",
		"short Desc",
		"Long Description",
		ExportIT.CliNamedParam(Curl),
		ExportIT.CliNamedParam(Cat),
	)
}

3. you are done!!

what is the catch?

• currently it work only with simple data types - string - int - bool
• currently only work with named arguments
• can't pipe things into it

todos:

• better shorthand naming
• cli for init sample
• arg first uppercase rune means required cli arg
• add positional args function
• instead of pos args func [FIRST LETTER for req]whateverTheArg[P0S] example "UrlP0S"
