KEEP
KEEP is a language evolution tracker and governance tool for the Kotlin programming language. It serves as a centralized portal for managing the lifecycle of language enhancement proposals and tracking the progression of syntax and semantic changes from initial design to final release.
The project functions as a technical proposal workflow engine to coordinate the review, acceptance, and revocation of formal design requests. It provides a system for documenting early ideas, integrating community feedback, and managing the evolution of language features.
The platform also handles programming language governance by documenting API stability levels and managing version compatibility markers for language components. This ensures that the maturity of features is communicated and that breaking changes are managed through a structured design process.
Features
- Language Evolution - Tracks the entire lifecycle of language features from initial design to final release.
- Proposal Lifecycles - Manages the evolution of language features through a state-based proposal lifecycle and committee consensus.
- Design - Provides a system to store preliminary design notes and explore syntax options before drafting formal proposals.
- Syntax Design - Documents and iterates on new syntax and semantic proposals to increase language expressiveness.
- API Stability Markers - Assigns API stability markers to designate the release stage and maturity level of language components.
- Feature Evolution Tracking - Tracks the progression of language features from initial design and community feedback through to stable release.
- Language Design Processes - Provides formal methods and community-driven processes for proposing and refining language features.
- Language Governance Portals - Provides a centralized repository for documenting stability levels and version compatibility for language components.
- Language Governance Tools - Provides a platform for managing API stability levels and version compatibility markers.
- Language Proposal Tracking - Provides a system for documenting design discussions and tracking the evolution of language proposals.
- Compiler Version Enforcers - Enforces specific version requirements to ensure consistent behavior and compatibility across different releases.
- Language Feature Feedback - Links external issue trackers and forums to gather real-world usage patterns and user opinions on proposed language changes.
- Community Feedback Channels - Integrates community feedback from external forums to inform the development of language features.
- Proposal Lifecycle Management - Provides a framework for tracking the end-to-end evolution of technical design proposals from drafting to implementation.
- Proposal Submission Workflows - Coordinates the review, acceptance, and revocation of formal design requests for language evolution.
- Version-Gated Compilation - Implements version-gated compilation to restrict specific syntax and APIs to designated releases.
- Stability Maturity Levels - Uses classification systems to define longevity and backward compatibility guarantees for software interfaces.
- Build and Development Tools - Extends build and development tools by connecting debuggers and language servers with package managers.
- Incremental Build Engines - Uses incremental build engines to track changes and execute only necessary compilation steps.
- Cross-Platform Application Development - Enables the development of applications that run across multiple target operating systems and environments.
- Multi-Target Compilers - Provides a multi-target compiler capable of transforming source code into various platform-specific formats.
- Standard Libraries - Maintains a core set of stable APIs for essential tasks like collection management and I/O.
- Cross-Platform Logic Sharing - Provides architectural strategies for sharing business logic across multiple native operating systems.
- Build Performance Optimization - Implements incremental build resolution to decrease compilation time and optimize dependency resolution.
- Cross-Platform Development - Supports a workflow for developing a single codebase targeting Android, iOS, Web, and desktop.
- Language Guides - Official repository for Kotlin language evolution proposals.
