Details

v0.3.0 deferred: tab completion, multi-line, /help, activity indicator, context persistence, theming

- Tab completion: Tab key autocompletes / commands (Tab handler in on-key)
- Multi-line input: backslash + Enter inserts literal newline instead of sending
- /help command: displays full command listing with descriptions
- Activity indicator: :busy flag shows "...thinking" in status bar during LLM wait
- Context persistence: context-save/context-load persist *context-stack* to disk
  (~/.cache/passepartout/context.lisp). Auto-restores on skill load.
  Added push-context, pop-context, focus-*, unfocus, context-save/load exports.
- Theming: *tui-theme* plist with semantic color roles, /theme command
  View functions (view-chat, view-status, view-input) use theme-color
- TUI test suite: 19 tests, 53 checks (100% pass)
- Context test suite: 2 tests, 6 checks (100% pass)
- Total: 5 suites, 81 checks, 0 failures

Passepartout TUI — Model

Model

Model

The TUI state is a single plist accessed via st / (setf st). All state mutation flows through event handlers in the controller.

Contract

(init-state): returns a fresh state plist with :msgs list, :input buffer, :dirty flag, :busy flag, and :connection status.
(add-msg type text): appends a message to the :msgs list in *state*, tagged with a timestamp and type. Truncates at the message buffer limit.
(queue-event ev): thread-safely enqueues an event for the reader loop. (drain-queue) returns and clears the queue.

Package + State

(defpackage :passepartout.gateway-tui
  (:use :cl :croatoan :passepartout :usocket :bordeaux-threads)
  (:export :tui-main :st :add-msg :now :input-string
           :queue-event :drain-queue :init-state
           :view-status :view-chat :view-input :redraw
           :on-key :on-daemon-msg :send-daemon
           :connect-daemon :disconnect-daemon
           :*tui-theme* :theme-color))
(in-package :passepartout.gateway-tui)

(defvar *state* nil)
(defvar *event-queue* nil)
(defvar *event-lock* (bt:make-lock "tui-event-lock"))

(defvar *tui-theme*
  '(:user :green :agent :white :system :yellow :input :cyan
    :connected :green :disconnected :red :timestamp :yellow)
  "Color theme plist. Keys are semantic roles, values are Croatoan colors.")

(defun theme-color (role)
  "Returns the Croatoan color for a semantic role."
  (or (getf *tui-theme* role) :white))

(defun st (key) (getf *state* key))
(defun (setf st) (val key) (setf (getf *state* key) val))

(defun init-state ()
  (setf *state*
        (list :running t :mode :chat :connected nil :stream nil
              :input-buffer nil :input-history nil :input-hpos 0
              :messages nil :scroll-offset 0 :busy nil
              :dirty (list nil nil nil))))

Helpers

(defun now ()
  (multiple-value-bind (h m) (get-decoded-time)
    (format nil "~2,'0d:~2,'0d" h m)))

(defun input-string ()
  (coerce (reverse (st :input-buffer)) 'string))

(defun add-msg (role content)
  (push (list :role role :content content :time (now)) (st :messages))
  (setf (st :dirty) (list t t nil)))

Event Queue

(defun queue-event (ev)
  (bt:with-lock-held (*event-lock*) (push ev *event-queue*)))

(defun drain-queue ()
  (bt:with-lock-held (*event-lock*)
    (let ((evs (nreverse *event-queue*)))
      (setf *event-queue* nil) evs)))
