Deploy (Gitea) / deploy (push) Failing after 3s
- 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

#+TITLE: Passepartout TUI — Model
|
|
#+PROPERTY: header-args:lisp :tangle ../lisp/gateway-tui-model.lisp
|
|
|
|
* Model
|
|
|
|
The TUI state is a single plist accessed via ~st~ / ~(setf st)~.
|
|
All state mutation flows through event handlers in the controller.
|
|
|
|
** Contract
|
|
|
|
1. (init-state): returns a fresh state plist with ~:msgs~ list,
|
|
~:input~ buffer, ~:dirty~ flag, ~:busy~ flag, and ~:connection~ status.
|
|
2. (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.
|
|
3. (queue-event ev): thread-safely enqueues an event for the
|
|
reader loop. (drain-queue) returns and clears the queue.
|
|
|
|
