Module input_state 

Input mode and prompt-input state for the Recursive TUI.

Contains the multi-mode input machinery: InputMode, the mutable PromptInputState buffer, double-press tracking for Esc/Ctrl+C, and history-ring management.

Structs

DoublePressTracker

Tracks when the user last pressed Esc / Ctrl+C. Goal 147 maps a “double press within window” to a stronger action (real exit on the second Ctrl+C) while a single press triggers the context-dependent path (interrupt / clear buffer / pop modal).

PromptInputState

Mutable state of the multi-mode prompt input.

Enums

InputMode

Which input mode the PromptInput is currently in.

Constants

DOUBLE_PRESS_WINDOW

Default window for double-press detection (Esc / Ctrl+C). The runtime can override this via the RECURSIVE_TUI_DOUBLE_MS env var — see double_press_window.

HISTORY_CAPACITY

Maximum number of history entries to retain in the ringbuffer.

Functions

double_press_window

Resolve the active double-press window. Reads RECURSIVE_TUI_DOUBLE_MS once per call (cheap; this is hit only on keypress) and falls back to DOUBLE_PRESS_WINDOW on parse failure.
