Reviving Halyra IDE: A Kotlin Compose Desktop comeback story

A developer’s journey of refining a long-abandoned Python IDE into a polished Kotlin Compose Desktop project, using GitHub Copilot to streamline code and fix critical issues.

A decade-long fascination with integrated development environments (IDEs) led one developer to revisit Halyra, a Python-based IDE originally built with PySide6. After pausing development due to tangled code and freezing problems during compilation, the project lay dormant—until the GitHub Finish-Up-A-Thon Challenge reignited the passion for completion.

This time, the focus shifted to Kotlin Compose Desktop, a modern framework promising cleaner architecture and smoother cross-platform performance. Rather than discarding the original codebase, the developer chose to extract its strengths, refactor its structure, and rebuild it from the ground up. The result is a more organized, maintainable IDE that balances functionality with clarity—years of technical debt finally resolved.

From Fragmented Code to a Streamlined IDE

The first iteration of Halyra suffered from a common pitfall: sprawling monolithic files. Two massive Python scripts, each exceeding 1,000 lines, contained every function, class, and feature. Navigating the code was like exploring a labyrinth, and debugging became a daily challenge.

GitHub Copilot emerged as an unexpected ally in this cleanup mission. By analyzing the cluttered structure, Copilot suggested logical module divisions, splitting the code into smaller, purpose-built files. Functions were grouped by purpose—editor logic, project management, UI rendering—each stored in dedicated modules. This reorganization not only improved readability but also laid the foundation for future scalability.

Fixing the Freezing Issue That Halted Progress

One of the most persistent problems in the original Halyra was the frequent freezing during execution. Users would experience sudden UI lockups, especially when loading large projects or running resource-intensive tasks. After months of failed attempts to isolate the cause, the team suspected a threading or memory leak issue within the PySide6 backend.

Copilot helped pinpoint the root cause: inefficient event loop management and unoptimized file I/O operations. By refactoring the code to use asynchronous task scheduling and introducing proper resource cleanup routines, the freezing episodes were largely eliminated. These changes were later adapted into the Kotlin Compose version, where the framework’s built-in coroutine support made such optimizations even more efficient.

Introducing the Project Manager: A Key Addition

A robust project manager became a central feature in this revival. Unlike the early version, where project navigation was rudimentary, the new Halyra IDE now includes a dedicated panel for managing projects, files, and dependencies. Users can create new projects, import existing ones, and view a hierarchical file tree—all within a unified interface.

The project manager supports common file types out of the box, including Python, JSON, and Markdown. It also integrates with version control systems, offering basic Git operations like commit, push, and branch switching. This addition transforms Halyra from a simple text editor into a full-fledged development workspace, aligning with modern IDE expectations.

Lessons from GitHub Copilot: Coding with AI Assistance

The development journey with GitHub Copilot wasn’t just about fixing old problems—it was a masterclass in collaborative coding. Copilot acted as a co-pilot, suggesting refactorings, generating boilerplate code, and even documenting functions in real time. One particularly impactful use case was the automatic generation of unit tests for critical modules, reducing manual effort and improving reliability.

Three documented bug fixes now reside in the project’s documentation, each resolved with Copilot’s help. These include issues related to syntax highlighting lag, auto-completion delays, and project file corruption during save operations. While AI tools aren’t perfect, they proved invaluable in accelerating the cleanup and reducing cognitive load on the developer.

The future of Halyra IDE looks promising. The developer plans to expand language support, add debugging tools, and improve plugin architecture. With a solid foundation in Kotlin Compose Desktop, the project is poised to evolve into a versatile, community-driven IDE. For developers tired of bloated tooling, Halyra offers a refreshing blend of simplicity, performance, and modern architecture.
