Functions ¶

func GenerateRandomASCIIString ¶

func GenerateRandomASCIIString(n int) string

GenerateRandomASCIIString generates an ASCII random stirng with length n.

func GenerateRandomAlphaOnlyString ¶

func GenerateRandomAlphaOnlyString(n int) string

GenerateRandomAlphaOnlyString generates an alphabetical random string with length n.

func InSlice ¶

func InSlice(slice []string, s string) bool

InSlice tests whether a string is contained in a slice of strings or not. Comparison is case insensitive

func ShellQuoteArguments ¶

func ShellQuoteArguments(args []string) string

ShellQuoteArguments takes a list of strings and escapes them so they will be handled right when passed as arguments to an program via a shell

func Truncate ¶

func Truncate(s string, maxlen int) string

Truncate truncates a string to maxlen.

Types ¶

type StrSlice ¶

type StrSlice struct {
	// contains filtered or unexported fields
}

StrSlice representes a string or an array of strings. We need to override the json decoder to accept both options.

func NewStrSlice ¶

func NewStrSlice(parts ...string) *StrSlice

NewStrSlice creates an StrSlice based on the specified parts (as strings).

func (*StrSlice) Len ¶

func (e *StrSlice) Len() int

Len returns the number of parts of the StrSlice.

func (*StrSlice) MarshalJSON ¶

func (e *StrSlice) MarshalJSON() ([]byte, error)

MarshalJSON Marshals (or serializes) the StrSlice into the json format. This method is needed to implement json.Marshaller.

func (*StrSlice) Slice ¶

func (e *StrSlice) Slice() []string

Slice gets the parts of the StrSlice as a Slice of string.

func (*StrSlice) ToString ¶

func (e *StrSlice) ToString() string

ToString gets space separated string of all the parts.

func (*StrSlice) UnmarshalJSON ¶

func (e *StrSlice) UnmarshalJSON(b []byte) error

UnmarshalJSON decodes the byte slice whether it's a string or an array of strings. This method is needed to implement json.Unmarshaler.
