Keys are arbitrary nonempty strings, used as the protocol's `languageId`; they need no Tree-sitter grammar or hardcoded language enum. Absent/`false` entries are disabled. `true` enables a built-in preset: `"rust"` uses `rust-analyzer`/`rs`, `"python"` uses `ty server` plus `ruff server`/`py`, and `"ruby"` uses `solargraph stdio`/`rb`. Unknown keys need a configuration object with nonempty `command` argv or a `servers` list, plus `extensions` (without leading dots). Objects also explicitly enable servers; known presets supply omitted command/extensions. An explicit `command` replaces the entire preset with one server: `config.lsp["rust"] = { command: ["/custom/path/rust-analyzer"] }` retains `rs`, while a Python command override does not also launch Ruff.

Only `command`, `extensions`, `initialization_options`, `settings`, and `servers` are accepted. Options/settings must be JSON-compatible objects. Without an explicit command/list, options apply to every default server; explicit `initialization_options` replaces preset defaults. `servers` must be a nonempty ordered list of objects with explicit `command` and optional per-server `initialization_options`/`settings`; it shares language-level extensions and cannot be combined with top-level command/options/settings. Invalid declarations reject configuration with a notice rather than activating a guessed server. Commands are executable/argument arrays, never shell commands; use an absolute path if the executable is not on PATH. No server installation or restart is automatic.
Install Solargraph yourself with `gem install solargraph` in the project's Ruby environment. The Ruby preset launches `["solargraph", "stdio"]`, following [Solargraph's stdio integration](https://solargraph.org/guides/language-server), and uses [YARD annotations](https://solargraph.org/guides/yard) for type information. Explicit `command` overrides replace the entire argv: for a bundled installation, use `config.lsp["ruby"] = { command: ["bundle", "exec", "solargraph", "stdio"] }`; Vamp retains the `rb` extension but does not append `stdio` to your override.
Install [Tinymist](https://github.com/Myriad-Dreamin/tinymist#installation) separately and enable `config.lsp["typst"] = true` for `.typ` files. The preset launches `["tinymist", "lsp"]` with language ID `typst`; it does not enable preview or add export settings. Tinymist builds that return overlapping semantic tokens despite Vamp advertising no overlap support retain Tree-sitter highlighting and report the rejected tokens; hover and other LSP requests remain available. This occurs with the installed Typst 0.14.2-based build (`tinymist/v0.14.6-rc2`).
**Config-file lint style:** Solargraph's RuboCop reporter discovers `.rubocop.yml` from the Ruby file's directory, not Vamp's workspace. A config under `~/.config/vamp/` therefore does not inherit this repository's policy. To keep double quotes, multiline trailing argument commas, commented-out settings without a space after `#`, and no required frozen-string header, place this `.rubocop.yml` beside `config.rb` (also for a custom `--config` path):
```yaml
