Developer: RhinoScript
Summary: Discusses how to determine the version of RhinoScript from a running script.

Is there a good way to distinguish between scripts written in Rhino 3.0 versus those written in Rhino 4.0?

There is really not a good visual way to determine what version of Rhino a script was written for. Keep in mind that all RhinoScript functions found in V3 are also found in V4.

If it is important to know what version of Rhino a script was written for, the scripter should leave some clue behind in the script file. Perhaps a comment is sufficent. They might also have a block of code that only allows the script to run in a particular version.

For example:

 ' Check if the [[developer:rhinoscript|RhinoScript]] version is greater that 3.0 SR5b
 If CLng(Rhino.Version) > 20060519 Then
   Rhino.Print "This RhinoScript requires Rhino 3.0"
   Exit Sub
 End If

RhinoScript's Version method returns the version of RhinoScript as a long integer. The version of RhinoScript generally cooresponds to the version of Rhino unless you have downloaded and installed a Labs version. The following constants define the values returned by RhinoScript over the last several releases:

   Const RH_40_SR6  = 20090727 ' Rhino 4.0 SR6
   Const RH_40_SR5B = 20090226 ' Rhino 4.0 SR5b
   Const RH_40_SR5  = 20090116 ' Rhino 4.0 SR5
   Const RH_40_SR4B = 20080827 ' Rhino 4.0 SR4b
   Const RH_40_SR4  = 20080807 ' Rhino 4.0 SR4
   Const RH_40_SR3  = 20080222 ' Rhino 4.0 SR3
   Const RH_40_SR2  = 20071017 ' Rhino 4.0 SR2
   Const RH_40_SR1  = 20070703 ' Rhino 4.0 SR1
   Const RH_40_SR0  = 20070118 ' Rhino 4.0 SR0
   Const RH_30_SR5B = 20060519 ' Rhino 3.0 SR5b
   Const RH_30_SR5  = 20060331 ' Rhino 3.0 SR5
   Const RH_30_SR4  = 20050718 ' Rhino 3.0 SR4
   Const RH_30_SR3C = 20040421 ' Rhino 3.0 SR3c
   Const RH_30_SR3B = 20031209 ' Rhino 3.0 SR3b
   Const RH_30_SR3  = 20031111 ' Rhino 3.0 SR3
   Const RH_30_SR2  = 20030606 ' Rhino 3.0 SR2
   Const RH_30_SR1  = 20030305 ' Rhino 3.0 SR1
   Const RH_30_SR0C = 20021220 ' Rhino 3.0 SR0 CD3
   Const RH_30_SR0B = 20021125 ' Rhino 3.0 SR0 CD2
   Const RH_30_SR0  = 20021120 ' Rhino 3.0 SR0 CD1

You can determine the version of RhinoScript, and Rhino, that you are running using the following subroutine:

 Sub PrintRhinoVersion()
   Select Case CLng(Rhino.Version)
     Case RH_40_SR6  Rhino.Print("Rhino 4.0 SR6")
     Case RH_40_SR5B Rhino.Print("Rhino 4.0 SR5b")
     Case RH_40_SR5  Rhino.Print("Rhino 4.0 SR5")
     Case RH_40_SR4B Rhino.Print("Rhino 4.0 SR4b")
     Case RH_40_SR4  Rhino.Print("Rhino 4.0 SR4")
     Case RH_40_SR3  Rhino.Print("Rhino 4.0 SR3")
     Case RH_40_SR2  Rhino.Print("Rhino 4.0 SR2")
     Case RH_40_SR1  Rhino.Print("Rhino 4.0 SR1")
     Case RH_40_SR0  Rhino.Print("Rhino 4.0 SR0")
     Case RH_30_SR5B Rhino.Print("Rhino 3.0 SR5b")
     Case RH_30_SR5  Rhino.Print("Rhino 3.0 SR5")
     Case RH_30_SR4  Rhino.Print("Rhino 3.0 SR4")
     Case RH_30_SR3C Rhino.Print("Rhino 3.0 SR3c")
     Case RH_30_SR3B Rhino.Print("Rhino 3.0 SR3b")
     Case RH_30_SR3  Rhino.Print("Rhino 3.0 SR3")
     Case RH_30_SR2  Rhino.Print("Rhino 3.0 SR2")
     Case RH_30_SR1  Rhino.Print("Rhino 3.0 SR1")
     Case RH_30_SR0C Rhino.Print("Rhino 3.0 SR0 CD3")
     Case RH_30_SR0B Rhino.Print("Rhino 3.0 SR0 CD2")
     Case RH_30_SR0  Rhino.Print("Rhino 3.0 SR0 CD1")
     Case Else Rhino.Print("Unknown Rhino version")
   End Select
 End Sub
