TLang.Prompt

ask — Text Input

Prompt.ask displays a question and returns the user's input as a String.

      let name = Prompt.ask("Project name:")
      let pkg  = Prompt.ask("Base package (e.g. com.example):")
    

Prompt.askWithDefault provides a fallback shown in brackets if the user presses Enter without typing.

      let port = Prompt.askWithDefault("Port:", "8080")
      let host = Prompt.askWithDefault("Host:", "localhost")
    

confirm — Yes/No

Prompt.confirm displays a yes/no question and returns a Bool.

      let addTests = Prompt.confirm("Generate test scaffolding?")
      if (addTests) {
          // generate test files
      }
    

select — Choice from List

Prompt.select displays a numbered menu and returns the chosen string.

      let lang = Prompt.select("Target language:", List.of("kotlin", "java", "typescript"))
      let db   = Prompt.select("Database:", List.of("postgres", "mysql", "sqlite"))
    

password — Hidden Input

Prompt.password reads a value without echoing characters to the terminal.

      let secret = Prompt.password("API key:")
    

Example — Interactive Scaffolding

      use TLang.Prompt
      use TLang.File
      use TLang.Terminal
      use TLang.List

      func main(): String {
          let project = Prompt.ask("Project name:")
          let pkg     = Prompt.askWithDefault("Base package:", "com.example")
          let lang    = Prompt.select("Language:", List.of("kotlin", "java"))
          let tests   = Prompt.confirm("Include test scaffolding?")

          Terminal.println("Generating " + project + " (" + lang + ")...")

          // use answers to drive generation
          File.write("README.md", "# " + project, true)

          if (tests) {
              File.createDir("src/test")
          }

          Terminal.println("Done!")
          return "done"
      }
