What are Scripties?

Scripties are High Performance GUI equivalents of Console Scripts, that are Reliable and Easy to Make.

Categories :

• Built-In Scripties - Made in XAML & C# and Compiled. ( Static )
• User Made Scripties - Made in JSON and loaded by my Interpereter Dynamo. ( Dynamic )

---

A Temporary Halt on Development :

• I wouldn't provide updates for the next couple of months.
• Issues will be addressed and Pull Requests may be merged a bit late.
• All of this is because WinUI 3 is annoying and in return, no appreciation.
• I am not Maintaining this Project for a Wall, I am maintaining this as an example of What UI can be.
• v11.28000.17.0's Scientific Calc is VERY Confusing to make and will take Time & Experience ( in Math ).
• I will be making some of my own modules.

---

• Lack of Scientific Calculator ( Will be Fixed ) ❌
• Use of Alex Brush in Branding which may look like Alien Language for certain People. ❌

DETAILS ON DYNAMO :

Dynamo Scriptie Loader (DSL) is an Interpreter for JSON Code for creating a Dynamic UI for User-Made Math.

Features :

• Dynamically Generates a UI with the Required Fields and Formulae Entered by the User.

• ONE PAGE, MULTIPLE POSSIBILITIES. Yes, DyNamoPage.xaml is the Backbone of Any Scriptie Mod.

• Integrated Manager DyNamoManagerPage.xaml that Interprets the Mods and feeds this data into DyNamoPage.xaml to Load the UI.

• Very Clean & Simple Structure

    {
      "Metadata": {
        "Name": "", // This is What your Module Shows Up!
        "Author": "", // Write your Username.
        "Version": "", // This is the Version of your Scriptie.
        "Description": "", // Details
        "Repo": "" // Link ( If FOSS )
      },
      "UI": {
        "Formula": "", // Example W = F.S cos (theta)
        "Inputs": [
          { "Header": "Input Label", "Placeholder": "0.0", "Key": "var_name" } // Add as many as you like.
        ]
      },
      "Logic": {
        "Output": "NCalc math string using [var_name]", // Your Output. Example : "`Work Done = ` + F*S*Cos(Theta)"
        "Error": "Message if math fails" // Your Error.
      }
    }
  

• Thus, a Massive Time Saver and Low Barrier to Entry as one can make modules in Notepad.
• Since NCalc is NCalc and not a Compiler, the Risk of Malicious Mods is VERY LOW.

Steps to Use Dynamo Scriptie Loader:

• Go to Lamina ✦ Modules Repo.
• Download your Desired Mod, a .lamina File.
• Go to Menu > Press + Add and Add the File from the Popup!

so here's her Fictional Human Form! ヾ(^▽^*)))

Well I am no Artist, but I hope that you Have a Nice Time with Her!
