| // This file defines constants for non-standard CodeActions. |
| |
| // CodeAction kinds specific to gopls |
| // |
| // See ../protocol/tsprotocol.go for LSP standard kinds, including |
| // |
| // quickfix |
| // refactor |
| // refactor.extract |
| // refactor.inline |
| // refactor.move |
| // refactor.rewrite |
| // source |
| // source.organizeImports |
| // source.fixAll |
| // notebook |

| // Kinds are hierarchical: "refactor" subsumes "refactor.inline", |
| // which subsumes "refactor.inline.call". The "Only" field in a |
| // CodeAction request may specify a category such as "refactor"; any |
| // matching code action will be returned. |
| // |
| // All CodeActions returned by gopls use a specific leaf kind such as |
| // "refactor.inline.call", except for quick fixes, which all use |
| // "quickfix". TODO(adonovan): perhaps quick fixes should also be |
| // hierarchical (e.g. quickfix.govulncheck.{reset,upgrade}). |
| // |
| // # VS Code |
| // |
| // The effects of CodeActionKind on the behavior of VS Code are |
| // baffling and undocumented. Here's what we have observed. |
| // |
| // Clicking on the "Refactor..." menu item shows a submenu of actions |
| // with kind="refactor.*", and clicking on "Source action..." shows |
| // actions with kind="source.*". A lightbulb appears in both cases. |
| // A third menu, "Quick fix...", not found on the usual context |
| // menu but accessible through the command palette or "⌘.", |
| // displays code actions of kind "quickfix.*" and "refactor.*", |
| // and ad hoc ones ("More actions...") such as "gopls.*". |
| // All of these CodeAction requests have triggerkind=Invoked. |
| // |
| // Cursor motion also performs a CodeAction request, but with |
| // triggerkind=Automatic. Even if this returns a mix of action kinds, |
| // only the "refactor" and "quickfix" actions seem to matter. |
| // A lightbulb appears if that subset of actions is non-empty, and the |
| // menu displays them. (This was noisy--see #65167--so gopls now only |
| // reports diagnostic-associated code actions if kind is Invoked or |
| // missing.) |
| // |
| // None of these CodeAction requests specifies a "kind" restriction; |
| // the filtering is done on the response, by the client. |
| // |
| // In all these menus, VS Code organizes the actions' menu items |
| // into groups based on their kind, with hardwired captions such as |
| // "Extract", "Inline", "More actions", and "Quick fix". |
| // |
| // The special category "source.fixAll" is intended for actions that |
| // are unambiguously safe to apply so that clients may automatically |
| // apply all actions matching this category on save. (That said, this |
| // is not VS Code's default behavior; see editor.codeActionsOnSave.) |
