Source Code Spell Checkers

Harper is a local English linter and grammar checker designed as an IDE writing assistant. It operates as a language server that provides real-time spelling and grammar analysis for markdown and code comments, processing all linguistic data on the local device to ensure privacy and eliminate cloud dependencies. The tool is specialized for technical documentation, featuring the ability to identify and ignore text within code fences and inline blocks to prevent false positives. It allows for personalized configuration through custom dictionaries and the use of suppression comments to exclude sp

Prettier is an opinionated code formatter that parses source code and reprints it from scratch to enforce a consistent, project-wide visual style. By transforming code into an abstract syntax tree and applying a recursive document printing process, it eliminates manual style debates and ensures that all source files adhere to a unified appearance. The project is distinguished by its extensible, plugin-based architecture, which decouples language-specific parsing logic from the core engine. This modular design allows for uniform style enforcement across diverse programming languages and comple

Tree-sitter is a parsing system and incremental parsing framework designed to generate high-performance syntax trees from source code. It functions as a language parsing engine that compiles formal grammar definitions into portable code, which can then be integrated into text editors and development tools to facilitate structural analysis, code navigation, and syntax highlighting. The project distinguishes itself through its ability to maintain valid, usable syntax tree structures even when source code contains syntax errors or incomplete fragments. It utilizes a generalized parsing algorithm
