func CheckErr ¶

func CheckErr(msg any)

CheckErr prints the msg with the prefix 'Error:' and exits with error code 1. If the msg is nil, it does nothing.

func CommandLookPath ¶

func CommandLookPath() string

可执行文件的绝对路径

func Commands ¶

func Commands(commandName string, params ...string) (string, error)

脚本文件

func CompDebug ¶

func CompDebug(msg string, printToStdErr bool)

CompDebug prints the specified string to the same file as where the completion script prints its logs. Note that completion printouts should never be on stdout as they would be wrongly interpreted as actual completion choices by the completion script.

func CompDebugln ¶

func CompDebugln(msg string, printToStdErr bool)

CompDebugln prints the specified string with a newline at the end to the same file as where the completion script prints its logs. Such logs are only printed when the user has set the environment variable BASH_COMP_DEBUG_FILE to the path of some file to be used.

func CompError ¶

func CompError(msg string)

CompError prints the specified completion message to stderr.

func CompErrorln ¶

func CompErrorln(msg string)

CompErrorln prints the specified completion message to stderr with a newline at the end.

func Eq ¶

func Eq(a any, b any) bool

Eq takes two types and checks whether they are equal. Supported types are int and string. Unsupported types will panic.

func ExecuteCommand ¶

func ExecuteCommand(root *cobra.Command, args ...string) (output string, err error)

执行脚本

func ExecuteCommandC ¶

func ExecuteCommandC(root *cobra.Command, args ...string) (c *cobra.Command, output string, err error)

func ExecuteCommandWithContext ¶

func ExecuteCommandWithContext(ctx context.Context, root *cobra.Command, args ...string) (output string, err error)

ctx := context.TODO()

func ExecuteCommandWithContextC ¶

func ExecuteCommandWithContextC(ctx context.Context, root *cobra.Command, args ...string) (c *cobra.Command, output string, err error)

ctx := context.TODO()

func Gt ¶

func Gt(a any, b any) bool

Gt takes two types and checks whether the first type is greater than the second. In case of types Arrays, Chans, Maps and Slices, Gt will compare their lengths. Ints are compared directly while strings are first parsed as ints and then compared.

func MarkFlagCustom ¶

func MarkFlagCustom(flags *pflag.FlagSet, name string, f string) error

MarkFlagCustom adds the BashCompCustom annotation to the named flag, if it exists. The bash completion script will call the bash function f for the flag.

This will only work for bash completion. It is recommended to instead use c.RegisterFlagCompletionFunc(...) which allows to register a Go function which will work across all shells.

func MarkFlagDirname ¶

func MarkFlagDirname(flags *pflag.FlagSet, name string) error

MarkFlagDirname instructs the various shell completion implementations to limit completions for the named flag to directory names.

func MarkFlagFilename ¶

func MarkFlagFilename(flags *pflag.FlagSet, name string, extensions ...string) error

MarkFlagFilename instructs the various shell completion implementations to limit completions for the named flag to the specified file extensions.

func MarkFlagRequired ¶

func MarkFlagRequired(flags *pflag.FlagSet, name string) error

MarkFlagRequired instructs the various shell completion implementations to prioritize the named flag when performing completion, and causes your command to report an error if invoked without the flag.

func NoArgs ¶

func NoArgs(cmd *Command, args []string) error

NoArgs returns an error if any args are included.

func OnInitialize ¶

func OnInitialize(y ...func())

OnInitialize sets the passed functions to be run when each command's Execute method is called.

func OnlyValidArgs ¶

func OnlyValidArgs(cmd *Command, args []string) error

OnlyValidArgs returns an error if any args are not in the list of ValidArgs.

func WriteStringAndCheck ¶

func WriteStringAndCheck(b io.StringWriter, s string)

WriteStringAndCheck writes a string into a buffer, and checks if the error is not nil.
