# execx

Provides `os/exec.Cmd` wrappers.

``` go

import (

	"bytes"

	"context"

	"fmt"

	"github.com/berquerant/execx"

)

func main() {

	script := execx.NewScript(

		`echo line1

echo ${line2}

cat -

echo line3 > /dev/stderr`,

		"sh",

	)

	script.Env.Set("line2", "LINE2")

	if err := script.Runner(func(cmd *execx.Cmd) error {

		cmd.Stdin = bytes.NewBufferString("from stdin\n")

		_, err := cmd.Run(

			context.TODO(),

			execx.WithStdoutConsumer(func(x execx.Token) {

				fmt.Printf("1:%s\n", x)

			}),

			execx.WithStderrConsumer(func(x execx.Token) {

				fmt.Printf("2:%s\n", x)

			}),

		)

		return err

	}); err != nil {

		panic(err)

	}

	// Output:

	// 1:line1

	// 1:LINE2

	// 1:from stdin

	// 2:line3

}
