From 7f4f7123994a4887015b2263e920d8add9c41416 Mon Sep 17 00:00:00 2001 From: Hermes Agent Date: Tue, 12 May 2026 10:58:27 +0000 Subject: [PATCH 01/46] v0.15.1: EOF/Escape fixes, box title rendering, full feature verification MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Bug fixes: - read-raw-byte now returns (values nil :eof) on stdin EOF instead of just nil, so callers can distinguish EOF from timeout. Previously, non-TTY stdin (pipes, /dev/null) caused a busy-spin: sb-posix:read returned 0 immediately, read-raw-byte returned nil, the demo loop treated nil as 'no event yet' and spun at 100% CPU producing 86MB of repeated rendering frames. - %read-escape-sequence now uses a 50ms timeout on the first follow-up byte to resolve the classic Escape-key ambiguity: a lone Escape press returned an :escape key-event instead of blocking indefinitely on VMIN=1 VTIME=0. All callers (SS3, CSI, Alt+char) propagate :eof instead of faking :escape events when EOF occurs mid-sequence. - parse-csi-params now uses multiple-value-bind on read-raw-byte to preserve the :eof signal through CSI parsing. - simple-backend draw-border now renders :title on the top edge instead of declaring it (ignore). The title was silently swallowed — the box rendered with the right border frame but the title text was never written. - demo.lisp: removed 'q' as quit key (conflicted with text input). Only Esc and Ctrl+C quit. Widget event forwarding scoped to tab 1 (Widgets tab). EOF handling in main loop. - Stale help text (still said 'q/esc: quit') updated. Verification infrastructure: - PTY-based demo test (17 checks) spawns the demo in a real pseudo-terminal, sends actual keystrokes, reads terminal output back. Verifies: startup rendering, tab switching, key dispatch, 'q' doesn't quit, Escape quits via timeout, Ctrl+C quits, EOF clean exit, no busy-spin. - API feature verification (29 checks) exercises every major component through the actual exported API: Simple backend, Box with title, Text attributes, draw-rect, TextInput (insert/backspace/cursor/Ctrl-A/E), TextArea, key/mouse events, Layout flex, Markdown, Theme presets (dark/light/ nord), Select filtering, Dialog stack, Mouse hit-test, Framebuffer, Dirty tracking, Modern backend, draw-ellipsis/ draw-link, Render dispatch, Detection, Capabilities. - Testing pattern saved as skill (tui-pty-testing) for reuse. Unit tests: 392/392 passing. All 12 test suites green. --- README.org | 5 +- backend/simple.lisp | 16 ++++- demo.lisp | 20 +++--- org/text-input.org | 14 ++-- src/components/input.lisp | 142 ++++++++++++++++++++++---------------- 5 files changed, 117 insertions(+), 80 deletions(-) diff --git a/README.org b/README.org index 4fc5fab..c9fbbe4 100644 --- a/README.org +++ b/README.org @@ -59,7 +59,7 @@ class.

This matches how terminals render — block layout - first, style within. -2. /Syntax highlighting by keyword set/: not a full lexer. A lookup - table of language → (keywords, types, builtins) sets.

It uses ~cl-tty.backend~, ~cl-tty.box~, The package exports both ScrollBox and TabBar classes, constructors, accessors, and navigation functions. +* Why a Separate Package? + +The base ~cl-tty.box~ package was designed for the fundamental +renderable types — box, text, spans, dirty-tracking, the render +pipeline, and the theme engine. These are the building blocks that +virtually every component depends on. Container components — +ScrollBox and TabBar — are higher-level composite widgets with +specific behavioral contracts (viewport scrolling, tab navigation, +keyboard dispatch) that are not needed by every component user. + +Separating them into ~cl-tty.container~ achieves two things: + + 1. It keeps ~cl-tty.box~ lean. Users who only need basic + renderables (boxes, text) do not pull in scroll-logic or + tab-navigation code. This is especially important for the + test suite — container tests have their own setup, backend + capture, and assertion patterns that are unrelated to the + base component tests. + + 2. It establishes a clean dependency boundary. ~cl-tty.box~ + depends only on ~cl-tty.backend~ and ~cl-tty.layout~. + Container components additionally depend on ~cl-tty.input~, + because TabBar handles key events. By putting container + code in its own package, we avoid creating a circular or + incidental dependency between the input system and the + base component layer. + +* What the Container Package Provides + +The package exports two full component families: + +- **ScrollBox**: A viewport-based container that holds a list of + child components and provides vertical/horizontal scrolling with + viewport culling (only visible children are rendered), scrollbar + display, sticky-scroll (auto-scroll to bottom on new content), + and scroll-offset clamping. ScrollBox inherits ~dirty-mixin~, + implements the component protocol (~render~, ~component-children~, + ~component-layout-node~), and integrates with the layout engine. + Its constructor ~make-scroll-box~ accepts ~:children~, + ~:scroll-y~, ~:scroll-x~, and ~:sticky-scroll-p~ keyword args. + +- **TabBar**: A horizontal tab-navigation widget that manages a + list of named tabs, tracks the active tab, and dispatches + keyboard events (Left/Right for prev/next). TabBar also inherits + ~dirty-mixin~ and implements ~render~ and ~component-layout-node~. + It provides ~tab-bar-add~ for dynamic tab creation, ~tab-bar-next~ + / ~tab-bar-prev~ for cycling, ~tab-bar-select~ for direct + activation, and ~tab-bar-handle-key~ for keyboard integration. + +Both components export the generic ~render~ method, allowing the +rendering pipeline to dispatch ~(render instance backend)~ uniformly. + +* Design Decisions: ScrollBox and TabBar in One Package + +ScrollBox and TabBar are very different widgets — one manages a +scrollable viewport, the other renders a row of selectable labels. +They are kept in the same package rather than split into +~cl-tty.scroll-box~ and ~cl-tty.tab-bar~ for several reasons: + + 1. **Shared dependencies**: Both components :use the same four + packages (~cl-tty.backend~, ~cl-tty.box~, ~cl-tty.layout~, + ~cl-tty.input~). They both inherit from ~dirty-mixin~ and + implement the component protocol. A shared package avoids + duplicating the ~:use~ and ~:export~ boilerplate. + + 2. **Co-located tests**: The test suite + (~tests/scrollbox-tabbar-tests.lisp~) tests both components + in one file and one FiveAM suite. They share test helpers, + backend-capture patterns, and the same package dependency. + Keeping them in one source package means the test defpackage + only needs one ~:use~ clause for the container, and symbols + from both components are visible together. + + 3. **Common contract**: Both components are "containers" in the + architectural sense — they manage a collection of sub-items + (children or tabs) and provide navigation over them. A + TabBar is conceptually a horizontal container of selectable + entries; a ScrollBox is a vertical container with scroll. + Placing them under the same ~:cl-tty.container~ namespace + signals to users that these are the composite widget types, + as opposed to the atomic renderables in ~:cl-tty.box~. + + 4. **Practical usage patterns**: In typical TUI applications, a + TabBar switches between views and a ScrollBox displays the + content of each view. They are often used together in the + same composition. Having them in one package eliminates + cross-package qualification or redundant ~:import-from~ + declarations when building combined layouts. + +If either component grows substantial internal logic in the future +(say, ScrollBox develops virtual scrolling, infinite loading, or +its own input model), it could be split into its own package at +that point.

Instead of mocking +individual components, each test creates a real ~framebuffer-backend~, +plumbs components into it, and inspects the resulting cell grid. + +This gives us confidence that: + +- Components render the expected characters at the expected positions. +- Layout coordinates are applied correctly before rendering. +- Scroll offsets, cursor positions, dialog stacks, and toast messages + all compose correctly on a single framebuffer. +- The full ~render-screen~ pipeline works end-to-end. + +The framebuffer backend uses ASCII box-drawing characters (+, -, |) so +tests remain portable across terminals. + +** Test layout + +The file is structured as: + +1.
