I couldn't understand what Though I am curious on how will this work. |
That was indeed quite vague. In my unit-test I created an 'answering machine' that sends strings to the 'StdIn' based on lines read from 'StdOut'. It works a little bit like this: questionsAndAnswers := map[string]string{
"How are you doing?": "I'm fine thanks!",
"Are you sure you want to do this?": "\033[C", // Right arrow key to move around in the prompt
}
// Stdout replacement
outputReader, outputWriter := io.Pipe()
defer outputReader.Close()
defer outputWriter.Close()
// Stdin replacement
inputReader, inputWriter := io.Pipe()
defer inputReader.Close()
defer inputWriter.Close()
go func() {
reader := bufio.NewScanner(outputReader)
for reader.Scan() {
line := reader.Text()
// Loop through questions and answers
// [...]
if answerFound {
inputWriter.Write([]byte(answer) + "\n\r")
}
}
}()
form := huh.NewForm().
WithOutput(outputWriter).
WithInput(inputReader).
Run()Not sure if you're looking for something like this in your documentation, but I enjoy sharing it :) |

Replace properties such as `Options`, `Title`, `Description` with their dynamic counterparts: `OptionsFunc`, `TitleFunc`, and `DescriptionFunc` to recompute properties values on changes when watched variables change. Let’s build a simple state / province picker. ```go var country string var state string ``` The `country` select will be static, we’ll use this value to recompute the options and title for the next input. ```go huh.NewSelect[string](). Options(huh.NewOptions("United States", "Canada", "Mexico")...). Value(&country). Title("Country"). ``` Define your `Select` with `TitleFunc` and `OptionsFunc` and bind them to the `&country` value from the previous field. Whenever the user chooses a different country, the `TitleFunc` and `OptionsFunc` will be recomputed. > \[!IMPORTANT] > We have to pass `&country` as the binding to recompute the function only when > `country` changes, otherwise we will hit the API too often. ```go huh.NewSelect[string](). Value(&state). Height(8). TitleFunc(func() string { switch country { case "United States": return "State" case "Canada": return "Province" default: return "Territory" } }, &country). OptionsFunc(func() []huh.Option[string] { opts := fetchStatesForCountry(country) return huh.NewOptions(opts...) }, &country), ``` Lastly, run the `form` with these inputs. ```go err := form.Run() if err != nil { log.Fatal(err) } ``` ##### Other Changes #### What's Changed -
