Managed components

Vixl downloads a catalog of language servers, and runs CodeGraph via npx. PATH-only catalog rows are not downloaded. Project-local linters have no managed installer. How to use language servers in the editor: Language servers. How the graph is used in chat: Code graphs.

CodeGraph

Package: @colbymchenry/codegraph (unpinned; npx fetches current).

When you activate a project, Vixl starts CodeGraph for that root. If codegraph.db is missing it runs npx -y @colbymchenry/codegraph init. Rebuild from the Graph tab runs index --force. The MCP server is npx -y @colbymchenry/codegraph serve --mcp --path {root}. Indexes live under personal .vixl/graphs/{sha256}/ (codegraph.db, meta.json, _preload.cjs), never in the repo. The folder name is the SHA-256 hex of the canonical absolute project root.

Vixl sets CODEGRAPH_TELEMETRY=0 so the package's own telemetry is off. It also sets CODEGRAPH_NO_UPDATE_CHECK=1. This is the only telemetry-related string in the app. See Privacy.

There is no settings.json key to disable CodeGraph. It starts again the next time you activate the project. You can delete a stored index from Settings > Graphs (the next activate runs init again). Stop from the chat graph chip lasts until the next activate. A user codegraph entry in mcp.json is stripped.

Language servers Vixl installs

Installs go under personal ~/.vixl/lsp/{id}/{version}/. npm servers also use a portable Node at ~/.vixl/runtime/node/. State (enabled, disabled, command overrides) is personal lsp.json.

When you activate a project, Vixl prefetches the default set (TypeScript / JavaScript, JSON, YAML, Markdown) if auto-download is on. Settings > LSP, Install defaults does the same.

Install kinds: npm package, GitHub release (repo / tag / asset), HTTP archive, or go install.

{target} is a platform token (Rust triple, OS name, or similar, per server). {version} is the tag without extra prefix when the asset template includes it.

PATH-only (not downloaded)

These catalog rows use a binary already on PATH: deno, ruby, csharp, swift, elixir, haskell, ocaml, dart, gleam, nix, r, scala.

Project-local linters eslint, oxlint, and biome have no managed installer. They require workspace trust. See settings.json (workspace.trust).

Turn language servers off

  • Settings > LSP: turn off Auto-download (lsp.autoDownload, personal). Prefetch on project activate becomes a no-op.
  • Environment: VIXL_DISABLE_LSP_DOWNLOAD set to 1, true, TRUE, or yes also skips prefetch, even if the setting is on.
  • Settings > LSP, or lsp.json: disable individual servers. lsp.json set to false disables all of them.
  • Uninstall a managed install from the LSP row. Files remain under .vixl/lsp/ until removed.

lsp.* cannot be overridden by a project settings.json.
