How can I go about handling this raw arguments string and assoicate it with an action?

This is not concerning a programming error I am having but a design issue that I cant seem to get to the bottom of.

I wrote a AHK program that uses Search Everything, to execute small AHK programs/Utilities. On the search bar I can optionally type >: and everything after it will also be passed to the program to be run, as a raw string, At this point the program and everything are eliminated out of the equation.

HERE is a image to show what I am talking about, in this image when I execute Insert Frame.ahk without "Operator" >:, a single frame gets inserted, but with >:17 then 17 frames. >: is a feature I defined in everything, everything after it does not affect the search result.

The targeted AHK script, via Passing parameters to a script receives the arguments as a single raw string, up to now, I have only been passing a single argument, so its been straight forward, inside Insert Frames.ahk:

If (A_Args [1] = ""){  ;If not argument sent in, do the default action
    ClipPaintAutoAction("AnimInsertFrame", "1")  ;Insert 1 frame     This is a function that speaks to the animation softwares automation interface
    ExitApp
    }
Arg1 :=  A_Args[1]
ClipPaintAutoAction("AnimInsertFrame", Arg1) ;Insert nth Frames      This is a function that speaks to the animation softwares automation interface
ExitApp

I have been using this utility for less than a month and I was surprised, at how effective it has made me, so I have started using it in more software/packages and with that I expanded from passing 1 parameter\value to 3,

So Insert Frame.ahk can now accept up to 3 parameters, >:17,SpliTrack,ActiveLayer

I really wish to avoid making the command bar interface rigid by only accepting full parameter names, I am really trying to make the following entries equally valid:

In the Insert Frame.ahk script:

;---------- Various examples of what the script recieves at run time -------------------------
    A_Args[1] := "17,SplitTrack,ActiveLayer"
    A_Args[1] := "17,st,alayer"
    A_Args[1] := "17,s
    A_Args[1] := "17,,a"

Arguments := Split(A_Args[1], ",") 

;----------  Various Post Split\Cleanup Examples ----------------------
    Arguments := ["17", "SplitTrack", "ActiveLayer"]
    Arguments := ["17", "st", "alayer"]
    Arguments := ["17","s", ""]
    Arguments := ["17", "", "a"]

;----------  Action to take ----------------------
    Do Action 0  --> If Arguments  = "" then do default  <---- This one I know how to perform :D
    Do Action 1  --> Insert 17 frames only
    Do Action 2  --> Insert 17 frames and SplitTrack only
    Do Action 3  --> Insert 17 frames and ActiveLayer only
    Do Action 4  --> Insert 17 frames and SplitTrack and ActiveLayer

In the script there can only ever be 5 possible actions to take, I am struggling with how I can logically identify the state of Arguments object and do its relative action, since Arguments variable can take quite a few different forms. I don't see how I can anticipate it or perform logical matching operations

I use command line tools and PowerShell heavily and this is something they excel at. I am hoping someone that is familiar with how they work can share some insight with me.

Any help would be greatly appreciated!

Since the condition for executing an action is only required that the Arguments is not empty. In AutoHotKey, a variable is treated as TRUE if it contains any value other than FALSE/ 0/ "".

So, there are many ways to achieve your goal. For me, the first thing that comes to mind when I meet the if a is true, do a; if b is true, do b situation, will be organizing them into a Map object, but in your case, 2 simple array will works fine too.

This is an example for Array: Using For-loop

Arguments  := ["17"   , "SplitTrack", "ActiveLayer"]
ActionFunc := [Action1,   Action2   ,    Action13  ] 

For Arg in Arguments 
    !Arg ? default_Action() : ActionFunc[A_Index]()

! equal to not, so, !Arg means that the value of Arg is one of FALSE/ 0/ "".
