Input, Keys, and Autocomplete

Key Parsing

File: indusagi/src/tui/keys.ts

Key types and helpers:

• KeyId is a type-safe union of key identifiers.
• Key is a helper for building key identifiers.
• parseKey(data) returns the key identifier for raw input.
• matchesKey(data, keyId) checks if input matches a key identifier.
• isKeyRepeat and isKeyRelease handle Kitty keyboard protocol events.

Kitty CSI-u sequences are supported for printable keys. Shift and base layout handling is implemented in the editor to preserve correct characters.

Keybindings

File: indusagi/src/tui/keybindings.ts

• EditorAction enumerates editor actions.
• EditorKeybindingsManager maps actions to keys and exposes matches.
• DEFAULT_EDITOR_KEYBINDINGS is the default mapping.
• getEditorKeybindings returns the global manager.

Input Buffering

File: indusagi/src/tui/stdin-buffer.ts

• StdinBuffer splits raw stdin into complete escape sequences.
• Supports CSI, OSC, DCS, and APC sequences.
• Emits data events for key sequences and paste events for bracketed paste.

Autocomplete

File: indusagi/src/tui/autocomplete.ts

• AutocompleteProvider defines getSuggestions and applyCompletion.
• CombinedAutocompleteProvider supports slash commands and file paths.
• Fuzzy file search uses @prefix syntax.
• File completion can use the external fd binary if present.

Fuzzy Matching

File: indusagi/src/tui/fuzzy.ts

• fuzzyMatch(query, text) returns a score.
• fuzzyFilter(items, query, getText) filters and sorts by score.
