Cli Util

cliutil provides some extra util functions for CLI.

  • Helper util functions in cli
  • Color print in console terminal
  • Read terminal message input
  • Command line args string parse
  • Build command line string from []string

Install

go get github.com/gookit/goutil/cliutil

Go docs

Helper functions

cliutil.Workdir() // current workdir
cliutil.BinDir() // the program exe file dir
cliutil.QuickExec("echo $SHELL")

Color print

Quick color print in console:

cliutil.Redln("ln:red color message print in cli.")
cliutil.Blueln("ln:blue color message print in cli.")
cliutil.Cyanln("ln:cyan color message print in cli.")

color-print

Read input

name := cliutil.ReadInput("Your name: ")
name := cliutil.ReadLine("Your name: ")

ans, _ := cliutil.ReadFirst("continue?[y/n] ")
if cliutil.InputIsYes(ans) {
	// do something ...
}

ans, _ := cliutil.ReadFirstByte("continue?[y/n] ")
if cliutil.ByteIsYes(ans) {
	// do something ...
}
Read Password
pwd := cliutil.ReadPassword("Input password:")

Parse command line as args

parse input command line to []string, such as cli os.Args

package main

import (
	"github.com/gookit/goutil/cliutil"
	"github.com/gookit/goutil/dump"
)

func main() {
	args := cliutil.ParseLine(`./app top sub --msg "has multi words"`)
	dump.P(args)
}

output:

PRINT AT github.com/gookit/goutil/cliutil_test.TestParseLine(line_parser_test.go:30)
[]string [ #len=5
  string("./app"), #len=5
  string("top"), #len=3
  string("sub"), #len=3
  string("--msg"), #len=5
  string("has multi words"), #len=15
]

Build command line from args

	s := cliutil.BuildLine("./myapp", []string{
		"-a", "val0",
		"-m", "this is message",
		"arg0",
	})
	fmt.Println("Build line:", s)

output:

Build line: ./myapp -a val0 -m "this is message" arg0
