!Stack.nsh
  I created a precompiler library to perform compiler time named stack operations. Well pseudo stack operations anyway. As a named stack is just a delimited !define with macros to Push, Pop, Exch, & Peek at the values.

PasteBin.com [!Stack.nsh]

I'm not quite sure how I'd use this yet, but it's still cool. (Any ideas?)

EXAMPLE:

     # Stack(TestStack): 5 4 2 1 0

   ${!Push} TestStack ${ValueTmp}  # Stack(TestStack): 3 5 4 2 1 0

     

   ${!Exch} TestStack 2            # Stack(TestStack): 4 5 3 2 1 0

   ${!Exch} TestStack 1            # Stack(TestStack): 5 4 3 2 1 0

    

   ${!Pop}  TestStack Value5       # Stack(TestStack): 4 3 2 1 0

   ${!Pop}  TestStack Value4       # Stack(TestStack): 3 2 1 0

   ${!Peek} TestStack Value3       # Stack(TestStack): 3 2 1 0

   ${!Pop}  TestStack Value3       # Stack(TestStack): 2 1 0

   ${!Pop}  TestStack Value2       # Stack(TestStack): 1 0

   ${!Pop}  TestStack Value1       # Stack(TestStack): 0

   ${!Pop}  TestStack Value0       # Stack(TestStack): EMPTY

  ;${!Pop}  TestStack ValueE       # Stack(TestStack): ERROR! Stack is Empty!


   !echo `5=${Value5}`

    !echo `4=${Value4}`

    !echo `3=${Value3}`

    !echo `2=${Value2}`

    !echo `1=${Value1}`

    !echo `0=${Value0}`

I just realized that my example code is incomplete... :cry:

I'll post a fix tomorrow...

Here is the complete example...

   !define !Stack_AllowRedefine

   !include "!Stack.nsh"


   ${!Push} TestStack 0            # Stack(TestStack): 0 

   ${!Push} TestStack 1            # Stack(TestStack): 1 0

   ${!Push} TestStack 2            # Stack(TestStack): 2 1 0

   ${!Push} TestStack 3            # Stack(TestStack): 3 2 1 0

   ${!Push} TestStack 4            # Stack(TestStack): 4 3 2 1 0


   ${!Exch} TestStack 1            # Stack(TestStack): 3 4 2 1 0

    

   !define  ValueTmp 5

   ${!Exch} TestStack ValueTmp     # Stack(TestStack): 5 4 2 1 0

   ${!Push} TestStack ${ValueTmp}  # Stack(TestStack): 3 5 4 2 1 0

     

   ${!Exch} TestStack 2            # Stack(TestStack): 4 5 3 2 1 0

   ${!Exch} TestStack 1            # Stack(TestStack): 5 4 3 2 1 0

    

   ${!Pop}  TestStack Value5       # Stack(TestStack): 4 3 2 1 0

   ${!Pop}  TestStack Value4       # Stack(TestStack): 3 2 1 0

   ${!Peek} TestStack Value3       # Stack(TestStack): 3 2 1 0

   ${!Pop}  TestStack Value3       # Stack(TestStack): 2 1 0

   ${!Pop}  TestStack Value2       # Stack(TestStack): 1 0

   ${!Pop}  TestStack Value1       # Stack(TestStack): 0

   ${!Pop}  TestStack Value0       # Stack(TestStack): EMPTY

  ;${!Pop}  TestStack ValueE       # Stack(TestStack): ERROR! Stack is Empty!


   !echo `5=${Value5}`

    !echo `4=${Value4}`

    !echo `3=${Value3}`

    !echo `2=${Value2}`

    !echo `1=${Value1}`

    !echo `0=${Value0}`

    ;!echo `E=${ValueE}` 

I vaguely remember having the ability to edit previous posts but I can't find it now.. :confused:

there's a limit on how long after you post before you can't edit it.
