Empryo's code intelligence runs a full LSP layer. It ships a Mason-backed installer so you can add servers for any language from the TUI without touching your Neovim config.

Commands

/lsp                open the LSP manager (install, enable, disable)
/lsp install        search and install servers (Mason registry, 576+ packages)
/lsp status         attached servers with PID, language, capabilities
/lsp restart        restart all, or filter by language

What the agent uses

Every code intelligence operation tries LSP first:

  • Go-to-definition
  • Find references
  • Workspace-wide rename
  • Diagnostics (errors, warnings, info)
  • Code actions (quick fixes, refactors)
  • Call hierarchy (incoming and outgoing)
  • Type hierarchy (super and subtypes)
  • Hover and type info
  • Format document and format range

No manual setup required. The agent picks the right tool automatically.

Dual backend

Empryo runs LSP in two modes, whichever is available:

ModeWhen
Neovim bridgeEditor panel open. Routes through your running Neovim LSP clients. Zero warm-up cost.
StandaloneEditor panel closed, or Neovim not installed. Empryo spawns LSP servers directly into ~/.empryo/lsp-servers/.

Both cover the same capabilities. Standalone servers stay warm as hot standby even when Neovim is open.

Supported languages

Typical LSP coverage (any Mason package works): TypeScript, JavaScript, Python, Go, Rust, Java, Kotlin, Scala, C#, Swift, Dart, Elixir, OCaml, Lua, C, C++, Ruby, PHP, Zig, Bash, CSS, HTML, JSON, TOML, YAML, Dockerfile, Vue.

Tree-sitter detection adds ReScript, Solidity, TLA+, Emacs Lisp, Objective-C, Nix, HCL/Terraform, Bazel/Starlark, Jsonnet, Makefile, GraphQL, Protobuf, SQL, Markdown, MDX, XML, and more.

For anything LSP doesn't cover, the intelligence router falls through to ts-morph (TypeScript/JavaScript AST), tree-sitter, and regex.

Mason installer

/lsp install opens a fuzzy-search browser over Mason's registry. Pick a package, press enter, Empryo installs it:

  • npm packages to ~/.empryo/lsp-servers/node_modules/
  • pypi via pip3
  • cargo via cargo install
  • golang via go install
  • github releases downloaded and extracted

Already installed locally or via your Neovim's Mason? Empryo picks them up from the existing paths.

Check health

/diagnose runs a full check: tree-sitter, LSP readiness, semantic indexing, Genome status. Use it when something doesn't feel right.
