Clojure for Nova

Clojure and ClojureScript language support for Panic Nova,
powered by clojure-lsp.

Version 2.0 is a complete rewrite. Version 1.x provided simple syntax
highlighting and jump-to-definition for locally-defined functions; 2.0 keeps
the bundled syntax and adds the full clojure-lsp language server — completion,
diagnostics, project-wide navigation, rename, formatting, and refactorings —
installing clojure-lsp automatically if it isn't already on your system.

Features

From the bundled syntax (works without a language server):

• Syntax highlighting for .clj, .cljs, .cljc, .cljx, .edn, .bb
• Symbol navigation — the Symbols list / jump bar shows your defs, defns,
  and namespaces (Nova drives its outline from the syntax, not the LSP)

Automatically from clojure-lsp via Nova's language client:

• Autocompletion
• Diagnostics / linting (clj-kondo, built into clojure-lsp)
• Hover documentation
• Go to definition and find references
• Code actions and refactorings
• Signature help

Via editor commands this extension adds (Nova doesn't wire these to the LSP
itself — see Commands below): rename and document formatting.

Note: Nova has no LSP semantic-token support, so highlighting comes from the
bundled grammar rather than clojure-lsp.

Requirements

The extension needs the clojure-lsp
binary. It is located automatically in this order:

1. The clojure-lsp executable path setting, if you set one.
2. A copy previously downloaded by this extension.
3. clojure-lsp on your shell PATH (e.g. installed via Homebrew).
4. Common install locations (/opt/homebrew/bin, /usr/local/bin).

If none of those succeed, the extension automatically downloads the official
native release for your Mac into its private storage — no setup required.

To install it yourself instead (recommended for control over the version):

brew install clojure-lsp/brew/clojure-lsp-native

Commands

Available from the Editor menu when a Clojure file is focused:

• Rename Symbol — rename the symbol at the cursor across the project
  (textDocument/rename).
• Format Document — format the file with cljfmt (textDocument/formatting).
• Clean Namespace (clojure-lsp) — run clojure-lsp's clean-ns
  refactoring on the current namespace.
• Restart clojure-lsp Server — relaunch the language server.

These commands use the bundled language client, so they require the
Language server management setting to be Bundled (the default).

Configuration

Both global and per-workspace:

• Enable clojure-lsp — turn the server on or off.
• clojure-lsp executable path — override binary discovery with an explicit
  path.
• Server trace — log LSP traffic to the Extension Console (off,
  messages, verbose).
• Language server management — Bundled (this extension launches and
  auto-installs clojure-lsp) or Nova-managed (defer to Nova 14's built-in
  language server management; install clojure-lsp from Settings → Languages).
• Format on save — automatically run Format Document on save (off by
  default).
• cljfmt config path — path to a cljfmt config file, forwarded to
  clojure-lsp (cljfmt-config-path). Leave blank to use clojure-lsp's own
  config (.lsp/config.edn).

Changelog

2.0.0

A complete rewrite around the clojure-lsp language
server. Version 1.x provided only simple syntax highlighting and local
jump-to-definition; 2.0 turns this into a full Clojure/ClojureScript development
extension.

• clojure-lsp integration via Nova's LanguageClient: completion, diagnostics
  (clj-kondo), hover, project-wide go-to-definition, find references, code
  actions, and signature help.
• Rename Symbol and Format Document commands (Nova doesn't auto-wire these to
  the language server, so they're implemented as commands), plus Clean Namespace.
• Automatic clojure-lsp discovery — configured path, PATH, common install
  locations — with automatic download/install of the official native release as
  a fallback.
• Rebuilt Clojure syntax for .clj, .cljs, .cljc, .cljx, .edn, .bb,
  with def/defn/ns symbol navigation (Symbols list / jump bar) and a
  function-call-position highlight heuristic.
• "Restart Server" editor command.
• Global and per-workspace settings for enable, executable path, trace, and
  language-server management (bundled vs. Nova-managed on Nova 14+).
• Resilient server lifecycle: retries through hot-reload races and auto-recovers
  from crashes with backoff.

1.0

• Simple Clojure syntax highlighting and jump-to-definition for locally-defined
  functions.
