StdinMBS.Echo as Boolean

Type Topic Plugin Version macOS Windows Linux iOS Targets
shared property Files MBS Util Plugin 17.4 ✅ Yes ✅ Yes ✅ Yes ❌ No Desktop, Console & Web
Enables/disables echo for stdin.
Example 
// try this on Mac/Linux GUI/Console app with the app launched from Terminal,
// or in console app on Windows launched from command prompt

dim s as new StdoutMBS

s.Write "Hello World"+chr(10)

dim t as string
dim n as integer = StdinMBS.ReadString(t)
s.Write chr(10)
s.Write "Read with echo: "+t+chr(10)

StdinMBS.Echo = false

n = StdinMBS.ReadString(t)
s.Write chr(10)
s.Write "Read without echo: "+t+chr(10)

StdinMBS.Echo = true

You can disable echo for password input.
By default it is enabled.
(Read and Write property)

StdinMBS.IsReady as boolean

Type Topic Plugin Version macOS Windows Linux iOS Targets
shared property Files MBS Util Plugin 12.3 ✅ Yes ❌ No ✅ Yes ❌ No Desktop, Console & Web
Checks whether there is data waiting in input buffer to be read.
Example 
Dim d As New date

Do
  // print time if second changed
  Dim e As New date
  If e.Second <> d.Second Then
    Print e.LongTime
    d = e
  End If
  
  // if ready, read a key
  If StdinMBS.IsReady Then
    Dim s As String
    Dim l As Integer = StdinMBS.ReadString(s)
    Print "Input "+Str(l)+": "+s
  End If
Loop

If IsReady returns false and you would call ReadString method, the app could be blocked until user types something on console.
Added Windows support in version 20.5. We return true, if there is a return in the input buffer, so you can call Read() functions.
