-The `onlyAdditions` setting (default: true) provides a focused, non-disruptive autocomplete experience: - -- Shows only forward-progressing suggestions (pure additions) -- Allows common prefix completions (e.g., "functio" → "function foo()") -- Hides all destructive changes (deletions, replacements without common prefix) -- Reduces cognitive load by keeping suggestions simple - -### IntelliSense Conflict Prevention - -The system actively prevents conflicts with VS Code's native IntelliSense: - -- Detects when IntelliSense is showing suggestions via `context.selectedCompletionInfo` -- Automatically cancels ghost suggestions when IntelliSense is active -- Ensures IntelliSense takes priority for immediate, context-specific completions -- Explicitly hides cached inline suggestions during typing to prevent conflicts - -### Mutual Exclusivity - -The system ensures only one suggestion is visible at a time: - -- When inline completion is shown for selected group, ALL other groups are hidden from SVG decorations -- Prevents visual confusion from multiple suggestions -- User sees exactly one actionable suggestion at a time -- TAB key navigates to next valid suggestion - -### Synthetic Group Creation - -The system intelligently combines separated deletion+addition groups: - -- When a deletion and addition group have a common prefix but were separated by grouping logic -- Creates synthetic modification groups for proper inline completion handling -- Ensures common prefix completions work correctly even with separated operations -- Handles edge cases like differing newLine values in operations diff --git a/src/services/ghost/GhostInlineCompletionProvider.ts b/src/services/ghost/GhostInlineCompletionProvider.ts index 6c11ec5abb8..94f18313de5 100644 --- a/src/services/ghost/GhostInlineCompletionProvider.ts +++ b/src/services/ghost/GhostInlineCompletionProvider.ts @@ -1,7 +1,6 @@ import * as vscode from "vscode" import { GhostSuggestionsState } from "./GhostSuggestions" import { GhostSuggestionEditOperation } from "./types" -import { GhostServiceSettings } from "@roo-code/types" // Constants const PLACEHOLDER_TEXT = "<<>>" @@ -18,16 +17,10 @@ const COMMON_PREFIX_THRESHOLD = 0.8 export class GhostInlineCompletionProvider implements vscode.InlineCompletionItemProvider { private suggestions: GhostSuggestionsState private onIntelliSenseDetected?: () => void -
