Eclipse Code Recommenders Overview
Eclipse Code Recommenders is an innovative plugin designed for the Eclipse Java Development Tools, aimed at enhancing the developer experience by providing intelligent code completion and other productivity-enhancing features.
What it Does
Eclipse Code Recommenders leverages the collective knowledge of the Java developer community to improve code completion suggestions. Instead of relying solely on alphabetical ordering or static lists, the plugin uses a database of usage patterns derived from large-scale analysis of open-source repositories, such as GitHub, and community contributions. This approach helps in managing the complexity of large APIs by suggesting methods and classes based on how frequently they are used by other developers in similar contexts.
Key Features and Functionality
1. Intelligent Code Completion
- The plugin offers code completion suggestions that are ranked based on their frequency of use by other developers. This ensures that the most commonly used methods and classes appear at the top of the suggestion list, making it easier for developers to find what they need quickly.
2. Subword Completion
- Code Recommenders includes a powerful subword completion feature, allowing developers to find methods or classes even when they only know a part of the name, not necessarily the beginning.
3. Extended Documentation
- The plugin provides an Extended Documentation view that shows information on how often certain methods are called or overridden. This is particularly useful for learning new APIs and understanding common usage patterns.
4. Smart Bug Detection and Call Chains
- Code Recommenders can help identify common call chains and methods that are frequently overridden when extending a class, aiding in debugging and code maintenance.
5. Snipmatch Code Snippet Search
- Integrated with the Snipmatch engine, the plugin allows developers to search for and insert code snippets provided by the community, facilitating the reuse of frequently occurring code patterns.
6. Crowd-sourced and Usage-Driven API Documentation
- The plugin aims to enrich API documentation by extracting and sharing real-world usage information from existing codebases, providing more practical insights into how APIs are actually used.
7. Community Feedback and Data Sources
- Although earlier versions had an option for community feedback by sending usage data to servers, this feature has been discontinued in later versions due to privacy concerns. Instead, the plugin relies on data mined from open-source repositories.
8. Customization and Offline Use
- Developers can configure the plugin to suit their needs, including disabling auto-download of recommendation models. The plugin can also be used in environments with limited or no internet connectivity by downloading and installing the models offline.
Additional Benefits
- Localization and Internationalization: The plugin is fully internationalized and relies on the Eclipse Babel project for localization, making it accessible to a broader audience.
- Performance and Stability: Code Recommenders is designed for daily use and has been optimized for performance and stability on standard development machines.
In summary, Eclipse Code Recommenders is a valuable tool for Java developers using the Eclipse IDE, offering intelligent code completion, extended documentation, and community-driven insights to enhance productivity and ease the learning curve of complex APIs.
