Module command_menu 

Command-completion popup (Goal 146).

When the prompt input is in crate::tui::app::InputMode::Command, the chat renderer overlays a small popup just above the input box that lists the candidate commands matching the current buffer.

The popup is purely visual — keyboard navigation lives in crate::tui::app::App::handle_command_menu_key, which is called from crate::tui::app::App::handle_key before falling through to the generic chat key path.

Constants

MAX_VISIBLE

Maximum number of candidate rows to display in the popup.

Functions

longest_common_prefix

Compute the longest common prefix of s1 and s2. Pure, used by tab_completion_target and exposed for tests.

popup_rect

Compute the rectangle to render the popup in, given the input box’s area and the number of candidate rows. Returns None when the popup doesn’t fit (terminal too short or candidates empty).

render

Render the popup. No-op when the input mode is not Command, the buffer is empty, or no matches are available.

render_atfile

Render the @file completion popup (Goal 158). No-op when not in AtFile mode or when the suggestion list is empty.

render_history_search

Render the Ctrl+R history-search popup (Goal 160). No-op when not in HistorySearch mode or when there are no matches to show.

render_permission_modal

Render the permission-request modal when a tool is waiting for user approval. Displayed as a centred overlay with the tool name, an abbreviated argument preview, and [Y]es / [N]o instructions.

tab_completion_target

Return the canonical name to autocomplete to, given the current buffer and the set of matches.
