In computing, Tree-sitter is a parser generator and incremental parsing library.
It is used to parse source code into concrete syntax trees usable in compilers, interpreters, text editors, and static analyzers. [2] [3] It is specialized for use in text editors, as it supports incremental parsing for updating parse trees while code is edited in real time, [4] and provides a built-in S-expression query system for analyzing code. [5]
Text editors which have official integrations with Tree-sitter include Atom, [6] GNU Emacs, [7] Neovim, [8] Lapce, [9] Zed, [10] and Helix. [11] Language bindings allow it to be used from programming languages including Go, Haskell, Java, JavaScript (with Node.js and WASM), Kotlin, Lua, OCaml, Perl, Python, Ruby, Rust, and Swift. Tree-sitter parsers have been written for these languages and many others. [12] GitHub uses Tree-sitter to support in-browser symbolic code navigation in Git repositories. [13]
Tree-sitter uses a GLR parser, a type of LR parser. [14] [15] [13]
Tree-sitter was originally developed by GitHub for use in the Atom text editor, where it was first released in 2018. [16] [6]
