Code intelligence

Inside Skink: Ctrl+E, then help code.

Language servers start on first use, when installed: rust-analyzer, typescript-language-server, basedpyright or pyright, gopls, dart language-server and zls. Inside EveryAI they come from EveryAI.

| Key | Does | |---|---| | Ctrl+Space | completion (also opens after two letters or . :: ->) | | Alt+K | type and docs of the symbol | | Alt+G / Alt+Shift+G | go to definition / type definition | | Alt+J | peek the definition in a popup | | Alt+R | references, in a results tab | | Alt+Enter | code actions: quick fixes, refactorings | | Alt+Shift+R | rename the symbol everywhere (:rn NEW) | | Alt+Shift+F | format the selection or file | | Ctrl+R / Alt+W | symbols in this file / in the project | | Shift+F8 | problems in the open files | | F6 / Shift+F6 | next / previous problem | | F1 | command palette |

In the completion list Up/Down choose, Enter or Tab insert, Esc closes; docs show beside it. Snippets select their first placeholder, Tab moves to the next. "autocomplete": false stops it opening by itself.

Signature help opens after ( and ,. Breadcrumbs show in the status line. "inlayhints": true shows type hints, "formatonsave": true formats on save. A lightbulb in the sign column means code actions are available. :impl lists implementations.

## Quick open

Alt+P (or :recent) lists tabs, recent and project files. A first character switches the list: > commands, @ symbols in the file, # symbols in the project. A / matches path segments in order: s/c/grade finds src/color/grade.rs.

## Refactoring

Edits to several files open the refactor preview: files and hunks with checkboxes and a side-by-side diff. Up/Down move, Space toggles, a all, n none, Enter applies (one undo step per file), Esc cancels.

| Command | Does | |---|---| | :safedelete | delete the function or type at the cursor once nothing outside uses it (:safedelete! previews it unchecked) | | :mv PATH | move or rename the file; servers update imports | | :extract var\|fn [NAME] | extract the selection (var also works without a server for Rust, TS/JS and Python) |

## Your own servers

In settings.json:

json "lsp.dart": "fvm dart language-server --protocol=lsp", "lsp.elixir": {"command": "elixir-ls", "extensions": ["ex", "exs"], "rootmarkers": ["mix.exs"], "initoptions": {}, "env": {}}, "lsp.python": false

Names: rust, typescript (also javascript, ts, js), python, go, dart, zig, or a new one. Changes apply at the next start.

:lsp shows the server a file gets, where it came from, its memory and progress; :lsp restart, :lsp log. A crashed server restarts once by itself; one with no open files for 10 minutes stops and starts again when needed.
