swank.nvim targets full SLIME feature parity via the Swank protocol. It is LSP-compatible: navigation and completion delegate to any attached LSP server, and Swank covers the features that fall outside the LSP spec.

Feature	Notes
REPL	Pane or floating output buffer, input history
Eval	Top-level form, expression before cursor, region, interactive
Completion	blink.cmp and nvim-cmp sources; fuzzy and exact; yields to LSP when present
Autodoc	Arglist echo on CursorHoldI
Compiler diagnostics	vim.diagnostic integration; auto-compile-on-save when no LSP is attached
Eval status	In-flight notification; interrupt with <Leader>eI
Compile file	Compile, compile-and-load, load file
SLDB debugger	Floating window; restarts, frame inspection, eval-in-frame, stepping
Object inspector	Navigable parts, back/reinspect
Cross-reference	Callers, references, bindings, sets, macroexpands, specializes
Macro expansion	macroexpand-1 and macroexpand-all
Disassembly
Trace dialog	SWANK-TRACE-DIALOG
Profiling
Thread management
LSP-first navigation	gd, K, gr, <C-k> delegate to LSP; Swank fills the gap when no LSP is present
Autostart	Spawns a CL implementation + Quicklisp automatically
which-key integration

• Compile region (compile a visual selection, not just a top-level form)
• Telescope and Trouble integration for xref and diagnostics
• Broader CL implementation testing (CCL, ECL, ABCL)
• Remote Swank server improvements (SSH tunnel helpers, connection profiles)
• Multiple simultaneous Swank connections
