A Rust crate for creating Abstract Syntax Trees (AST) and Language Server Protocol (LSP) servers powered by Tree-sitter
auto_lsp is a generic library for creating Abstract Syntax Trees (AST) and Language Server Protocol (LSP) servers.
It leverages crates such as lsp_types, lsp_server, salsa, and texter, and generates the AST of a Tree-sitter language to simplify building LSP servers.
auto_lsp provides useful abstractions while remaining flexible. You can override the default database as well as all LSP request and notification handlers.
It is designed to be as language-agnostic as possible, allowing any Tree-sitter grammar to be used.
See ARCHITECTURE.md for more information.
- Generates a thread-safe, immutable and iterable AST with parent-child relations from a Tree-sitter language.
- Supports downcasting of AST nodes to concrete types.
- Integrates with a Salsa database and parallelize LSP requests and notifications.
lsp_server: Enables the LSP server (uses lsp_server).
