var ErrBreak = errors.New("psuedo-break error")
ErrBreak represents a 'break' in environments that do not have a real break, like our WASM intepreter. Basically what happens in all cases would be:
- The Ask implementation panics with ErrBreak
- The handler for this invocation recovers from panics, and checks if recover() == ErrBreak.
- If it is, we should indicate to the caller (the web terminal) that the client used a break.
- The client should interpret this how it needs, which is going to emulate a normal terminal.
Functions ¶
func HiddenPrompt ¶
Types ¶
type Ask ¶
type Ask interface {
// Ask prints the given prompt and asks for input.
// It returns the input, or an error.
Ask(prompt string) (string, error)
// HiddenAsk is like Ask, but the input is hidden if possible.
HiddenAsk(prompt string) (string, error)
// Feedback prints the given feedback.
// This is usually used to print any output after the result of an Ask.
Feedback(line string)
}
Ask encapsulates the prompting and feedback of asking for input.
