wtf is tree-sitter-cpp?

tree-sitter-cpp is a grammar definition that lets the tree-sitter parsing tool understand C++ code. Think of tree-sitter as an engine that reads source code the way a browser reads HTML, it breaks text down into a structured, navigable form. This package adds C++ to the list of languages tree-sitter can parse, so tools like code editors, linters, or documentation generators can intelligently work with C++ files. At a high level, a "grammar" is essentially a set of rules describing how a language is put together, what counts as a function, a class, a template, or a namespace. This project packages those rules so that tree-sitter can take raw C++ source files and produce a structured tree representing the code's organization. That tree lets other software understand the code well enough to do things like highlight syntax accurately, jump to function definitions, or detect malformed constructs as you type. The people who'd reach for this are typically building developer tools. If you're making a code editor plugin that needs to understand C++ structure, writing a refactoring assistant, or creating a tool that analyzes C++ codebases for bugs or style issues, you'd use this grammar so you don't have to write your own C++ parser from scratch. C++ is notoriously complex to parse, so having a maintained grammar that plugs into the broader tree-sitter ecosystem saves a significant amount of work. The README itself is quite minimal, it names the project, links to the tree-sitter framework, and references a couple of external specifications for the C++ language's formal grammar. It's available through several package managers, which tells you it's intended as a dependency you pull into a larger project rather than a standalone tool. The real documentation lives in the main tree-sitter project, which explains how to use grammars once you've installed them.
