some useful cmds.

Example:

append to your root cmd.

import (
	gcmd "github.com/Laisky/go-utils/cmd"
)

func init() {
	rootCmd.AddCommand(gcmd.EncryptCMD)
}

Variables

var EncryptAESCMD = &cobra.Command{
	Use:  "aes",
	Long: `encrypt file by aes`,
	PreRunE: func(cmd *cobra.Command, args []string) error {
		return setupEncryptAESArgs(cmd)
	},
	Run: func(cmd *cobra.Command, args []string) {
		fs, err := os.Stat(gutils.Settings.GetString("inputfile"))
		if err != nil {
			gutils.Logger.Panic("read path", zap.Error(err))
		}

		if fs.IsDir() {
			if err = encryptDirFileByAes(); err != nil {
				gutils.Logger.Panic("encrypt files in dir", zap.Error(err))
			}
		} else {
			if err = encryptFileByAes(); err != nil {
				gutils.Logger.Panic("encrypt file", zap.Error(err))
			}
		}
	},
}

EncryptAESCMD encrypt files by aes

`go run cmd/main/main.go encrypt aes -i cmd/root.go -s 123`

var EncryptCMD = &cobra.Command{
	Use:  "encrypt",
	Long: `encrypt file`,
	Args: NoExtraArgs,
	PreRunE: func(cmd *cobra.Command, args []string) error {
		return setupEncryptArgs(cmd)
	},
	Run: func(cmd *cobra.Command, args []string) {
	},
}

EncryptCMD encrypt files

var GenTLS = &cobra.Command{
	Use:   "gentls",
	Short: "generate tls cert",
	Args:  NoExtraArgs,
	PreRunE: func(cmd *cobra.Command, args []string) error {
		return setupTLSArgs(cmd, args)
	},
	Run: func(cmd *cobra.Command, args []string) {
		gutils.Logger.Info("run generateTLSCert")
		generateTLSCert()
	},
}

GenTLS 生成 tls 证书

`go run -race cmd/main/main.go gentls --host 1.2.3.4`

注，RSA 证书没毛病，P256 的 ES 证书 Chrome 尚不支持 inspired by https://golang.org/src/crypto/tls/generate_cert.go

Functions

func Execute

func Execute()

Execute adds all child commands to the root command and sets flags appropriately. This is called by main.main(). It only needs to happen once to the rootCmd.

func NoExtraArgs

func NoExtraArgs(cmd *cobra.Command, args []string) error

NoExtraArgs make sure every args has been processed

do not allow any unprocessed args

Example

use with cobra.Command:

cmd = &cobra.Command{
    Args: NoExtraArgs,
}
