ADL Language Server

This repo contains an implementation of a language server for Algebraic Data Language and a VSCode extension implementing the corresponding language client.

Language Server

The language server conforms to the Language Server Protocol and uses tree-sitter to implement efficient parsing. The full grammar is defined in tree-sitter-adl.

The Rust code in adl-lsp borrows code and architecture from coder3101's implementation of Protols (a Protobuf Language Server).

✨ Features

When paired with the VSCode extension you will be provided

• ✅ Syntax highlighting (by guyNeara from adl-vscode-highlight)
• ✅ Goto definition and goto references
• ✅ Diagnostics
• ✅ Hover information

Further planned features

• 🚧 Symbol renaming
• 🚧 Import management
• 🚧 Code completion and suggestions
• 🚧 Formatting
• 🚧 Style and linting rules
• 🚧 Type-checking of interior JSON values
• 🚧 Plugins for other editors (neovim, helix)

Editor Support

VSCode

This repo implements a VSCode client extension that is published to the marketplace. See the README for futher configuration instructions.

Helix

[[language]]
name = "algebraic-data-language"
scope = "source.adl"
language-id = "adl"
file-types = ["adl", "adl-cpp", "adl-hs", "adl-java", "adl-hs", "adl-rs", "adl-ts"]

Vim

First install [adl-vim-highlight] for ADL file detection and syntax highlighting

vim.lsp.config["adl-lsp"] = {
  cmd = { "adl-lsp" },
  filetypes = { "adl" },
  root_markers = { ".git" },
}

vim.lsp.enable("adl-lsp")
