Implementation Status

This page provides a transparent overview of what's currently implemented in Droelang and what's planned for future development.

🎯 Current Status (January 2025)

Droelang is actively developed with a focus on WebAssembly compilation and emerging native bytecode execution.

✅ Fully Implemented Features

Core Language

• ✅ Variables and Assignment - Strong typing with set variable which is type to value
• ✅ Data Types - int, decimal, text, flag, date, list of T
• ✅ Display Output - display and show statements
• ✅ String Operations - Concatenation with + and interpolation with [variable]
• ✅ Conditionals - when condition then ... end when with otherwise
• ✅ Loops - for each item in collection ... end for
• ✅ Comments - Single-line // and multi-line /* */

Modules and Actions

• ✅ Module System - module name ... end module with namespacing
• ✅ Actions - Parameterized functions with action name with params gives type
• ✅ Return Values - give result and set variable from run module.action

Database DSL

• ✅ Data Definitions - data Entity with field annotations (key, auto, required, etc.)
• ✅ HTTP Endpoints - serve get /path ... end serve syntax
• ⚠️ Database Operations - Basic parsing implemented, runtime execution in progress

Compilation Targets

• ✅ WebAssembly - Primary target, fully functional (.droe → .wat → .wasm)
• ✅ Native Bytecode - @target droe compiles to .droebc format
• ⚠️ Rust Code Generation - @target rust with Axum framework (experimental)

CLI Tools

• ✅ Project Initialization - droe init creates project structure
• ✅ Compilation - droe compile file.droe to WebAssembly/bytecode
• ⚠️ Runtime Execution - droe run works for basic programs

🚧 Partially Implemented Features

Database and HTTP Features

• ⚠️ Database Runtime - Parsing works, runtime execution in development
• ⚠️ HTTP Server - serve endpoints parse, DroeVM runtime needed
• ⚠️ Multi-Database Support - Architecture exists, drivers in progress

Advanced Language Features

• ⚠️ Complex Collections - Basic list operations work, advanced manipulation pending
• ⚠️ Include System - File imports designed but needs testing
• ⚠️ Error Handling - Basic type checking, advanced error handling planned

Build System

• ⚠️ DroeVM Runtime - Native bytecode interpreter under development
• ⚠️ Release Builds - droe build --release planned for single-binary output

❌ Not Yet Implemented

Multi-Target Compilation

• ❌ Python Target - Not implemented (was documented but removed)
• ❌ Java/Spring Boot - Not implemented (was documented but removed)
• ❌ JavaScript/Node.js - Not implemented (was documented but removed)
• ❌ Go/Fiber - Not implemented (was documented but removed)

UI and Mobile Features

• ❌ UI Components - layout, form, input, button etc. (parsing exists, no compilation)
• ❌ Mobile Development - No Android or iOS support
• ❌ Cross-Platform UI - Not implemented

Advanced Features

• ❌ Format Expressions - format date as "MM/dd/yyyy" not implemented
• ❌ Advanced HTTP Client - call "url" method GET not implemented
• ❌ Complex Database Queries - Advanced query syntax not implemented
• ❌ Package Management - No module sharing system yet

🗺️ Development Roadmap

Priority 1: Core Stability (Q1 2025)

• Complete DroeVM bytecode runtime
• Stable database operations
• HTTP endpoint handling
• Production-ready WebAssembly compilation

Priority 2: Developer Experience (Q2 2025)

• Enhanced CLI tooling
• Better error messages
• Debugging support
• Performance optimization

Priority 3: Language Expansion (Q3+ 2025)

• Format expressions
• HTTP client operations
• Advanced database features
• Package management system

💭 Future Considerations

The following features were documented but are not currently in active development:

• Multi-Target Compilation - May be reconsidered based on community demand
• UI Framework - Significant effort required, priority unclear
• Mobile Development - Would require substantial mobile expertise

🚀 How You Can Help

Community Contributions

• Testing - Try Droelang with your use cases and report issues
