func Eprint ¶

func Eprint(args ...interface{})

Eprint is similar to fmt.Print but the output is stderr.

func Eprintf ¶

func Eprintf(format interface{}, args ...interface{})

Eprintf is similar to fmt.Printf but the output is stderr.

func Eprintfln ¶

func Eprintfln(format interface{}, args ...interface{})

func Eprintln ¶

func Eprintln(args ...interface{})

Eprintln is similar to fmt.Println but the output is stderr.

func Eval ¶

func Eval(exe interface{}, args ...string) string

Eval is similar to ExecWithStdout but with stdout captured and returned as a string. Trainling newlines are deleted.

func Exec ¶

func Exec(exe interface{}, args ...string) (error, int)

Exec runs a command. exe is the path to the executable and args are arugment passed to it.

Stdout/stderr are directed to the current stdout/stderr.

func ExecWithStdErrOut ¶

func ExecWithStdErrOut(exe interface{}, args ...string) (stdout, stderr string, err error, errCode int)

ExecWithStdout is similar to Exec but the stdout/stderr are captured and returned as the first/second return values.

func ExecWithStdout ¶

func ExecWithStdout(exe interface{}, args ...string) (stdout string, err error, errCode int)

ExecWithStdout is similar to Exec but the stdout is captured and returned as the first return value.

func Exists ¶

func Exists(p interface{}, args ...interface{}) bool

Exists checks whether the path exists

func Fatalf ¶

func Fatalf(msg interface{}, args ...interface{})

Fatalf prints a message and let the program exit with DefExitCode.

func I ¶

func I(v interface{}, def ...interface{}) int

I converts anything into an int. When the value is malformed, if the optional default value is specified, it is converted to int and returned; otherwise, 0 is returned.

func IsDir ¶

func IsDir(p interface{}, args ...interface{}) bool

IsDir returns true only if the path exists and indicates a directory

func IsFile ¶

func IsFile(p interface{}, args ...interface{}) bool

IsFile returns true only if the path exists and indicates a file

func Match ¶

Match use regular expression pattern to match str and returns all capturing groups.

func MustSucc ¶

func MustSucc(err error, code int)

MustSucc checks the result of Exec/Bash. If not succeed, exit the application.

func Printfln ¶

func Printfln(format interface{}, args ...interface{})

Printfln is similar to fmt.Printf but with a trailing new-line printed

func Pwd ¶

func Pwd() string

func S ¶

func S(v interface{}, args ...interface{}) string

S converts anything into a string. If args is specified, v is used as a format string.

func S2Is ¶

func S2Is(args ...string) (ifs []interface{})

S2Is returns a slice of interface{} given strings.

func ScriptDir ¶

func ScriptDir() string

ScriptDir returns the folder of the current script.

func ScriptName ¶

func ScriptName() string

ScriptName returns the filename of the current script not including the path.

func SortF ¶

func SortF(Len int, Less func(int, int) bool, Swap func(int, int))

SortF sorts the data defined by the length, Less and Swap functions.

func Succ ¶

func Succ(err error, code int) bool

Succ check whether return values of Exec and friends means succeed.
