Intelligent System Design Language (ISDL) is a custom programming language that enables you to create professional Virtual Tabletop Systems in hours, not months. It generates modern Foundry VTT systems compatible with Foundry V12 and V13 using cutting-edge web technologies.



ISDL provides both a **VS Code extension** and **CLI tool** for development, featuring syntax highlighting, intelligent validation, autocomplete, and seamless GitHub integration for publishing and sharing your systems.

## ✨ Key Features



### 🎨 Modern User Interface

* **Vue 3 + Vuetify** powered reactive character sheets for smooth, responsive gameplay

* **Advanced DataTables** with search, filter, sort, and drag-drop functionality - perfect for managing inventories and spell lists

* **Edit vs Play Mode** toggle for clear distinction between character building and gameplay

* **Responsive Design** optimized for desktop and tablet use



### ⚡ Enhanced Active Effects

* **Visual Editor** integration for creating effects through the familiar Foundry interface  

* **Smart Targeting** with automatic field detection and validation

* **Condition Management** with built-in status effect handling



### 🎲 Intelligent Game Mechanics  

* **Smart Dice Operations** - multiply a d4 by 2 and get a d8, because that makes sense for tabletop games

* **Enhanced Roll System** showing detailed breakdowns with labeled components

* **Conditional Visibility** - show Ki trackers only for Monks, spell slots only for casters, etc.

* **Resource Management** with automatic token bar integration and damage application



### 🔗 Seamless Publishing & Sharing

* **GitHub Integration** - authenticate, publish systems, and manage releases directly from VS Code

* **Automated Versioning** with semantic version detection based on your ISDL changes

* **Gist Sharing** for quick collaboration and system prototypes

* **Quality Releases** with auto-generated installation instructions and changelogs



### 🛠️ Developer Experience

* **VS Code Extension** with full language support, syntax highlighting, and intelligent autocomplete

* **CLI Tool** for build automation and CI/CD integration

* **Real-time Validation** catching errors as you type

* **Minimal Setup Needed** so you can get started easily



## 🚀 Quick Start



Ready to create your first system? Choose your preferred development environment:



### 📝 **VS Code Extension** (Recommended)

1. Install the [ISDL extension](https://marketplace.visualstudio.com/items?itemName=IronMooseDevelopment.isdl) from the VS Code marketplace

2. Create a new `.isdl` file and start coding with full intellisense support

3. Use `Ctrl+Shift+P` → `ISDL - Generate` to create your Foundry system

4. Connect to GitHub for easy publishing and sharing

## 🎯 Design Philosophy



### 1: Programming made easy, but still light programming



Systems like Simple World Building, Custom System Builder, and Sandbox all offer a no-code click based way to build out small lightweight systems.



ISDL is not nearly as complicated as developing a full Foundry system from scratch, but it is still a programming language. Basic familiarity with scripting languages as Javascript will be useful.



### 2: Do what makes sense



There are a lot of options and customization available, but if you use the default syntax it should provide a reasonable default.



When working with Datatypes like a list of Die size choices, most languages would reject `self.DieSize += 1` - adding `1` to a string doesn't make sense for most languages. For ISDL, we raise the value to the next die size, because that's what makes sense for Tabletop games. Multiply a d4 by 2? Now you have a d8.



### 3: Just enough Typing



Some programming languages have no typing, meaning you can pass a number to something that expects a string and the function will have to deal with it - or error. Even simple typos can error.



Other languages provide fully enforced typing which protects you from these mistakes, but can add a lot of extra work doing type conversions and checks.



ISDL provides just enough typing to protect yourself from things like typos and errors, without requiring a ton of extra work.
