From 1430924a1ceae35168a56424bc27fb4e28bfea66 Mon Sep 17 00:00:00 2001 From: tyulyukov Date: Wed, 29 Apr 2026 19:51:55 +0300 Subject: [PATCH 1/2] feat(web): vertical minimap for user messages Ports https://github.com/pingdotgg/t3code/pull/2348 by @akarabach. Adds a compact minimap rail on the right side of the chat that shows one dash per user message in the current thread. Hover expands it into a preview menu; click scrolls to that message. The active dash tracks scroll position. Hidable via a new "Chat minimap" toggle in the General settings panel. Cherry-picks the PR squashed onto MarCode main. MarCode adjustments vs upstream: - Imports changed from @t3tools/contracts to @marcode/contracts. - ClientSettingsPatch additions limited to hideChatMinimap (upstream PR also brought along sidebarProjectGroupingMode/Overrides because they were in upstream main when the PR was based; MarCode already has those in ClientSettingsSchema, so no patch entry needed for this PR). - SettingsPanels.useSettingsRestore restore-list adds only "Chat minimap" (upstream brought "Task sidebar" too; not yet in MarCode). - MessagesTimeline keeps MarCode's existing rows = useMemo(...) (upstream introduced a useStableRows wrapper for structural sharing; MarCode doesn't have it and the minimap doesn't require it). - LegendList wrapped in
with conditional pr-2 when minimap visible (parent already has px-3 sm:px-5 from ChatView, so the right padding is incremental). - ChatMinimap threadKey wired to threadId (upstream uses routeThreadKey, a prop MarCode doesn't have). - Test fixtures in clientPersistence.test.ts and localApi.test.ts refactored to Schema.decodeSync(ClientSettingsSchema)({...non-default}), matching upstream's cleaner pattern while preserving MarCode's intent of round-tripping non-default values. --- apps/desktop/src/clientPersistence.test.ts | 16 +- .../components/chat/ChatMinimap.browser.tsx | 353 +++++++++++ .../src/components/chat/ChatMinimap.logic.ts | 207 +++++++ apps/web/src/components/chat/ChatMinimap.tsx | 258 ++++++++ .../chat/MessagesTimeline.logic.test.ts | 579 ++++++++++++++++++ .../src/components/chat/MessagesTimeline.tsx | 44 +- .../components/settings/SettingsPanels.tsx | 28 + apps/web/src/components/ui/preview-card.tsx | 49 ++ apps/web/src/localApi.test.ts | 52 +- packages/contracts/src/settings.ts | 2 + 10 files changed, 1525 insertions(+), 63 deletions(-) create mode 100644 apps/web/src/components/chat/ChatMinimap.browser.tsx create mode 100644 apps/web/src/components/chat/ChatMinimap.logic.ts create mode 100644 apps/web/src/components/chat/ChatMinimap.tsx create mode 100644 apps/web/src/components/ui/preview-card.tsx diff --git a/apps/desktop/src/clientPersistence.test.ts b/apps/desktop/src/clientPersistence.test.ts index f75f44d02a8..fa5456d4998 100644 --- a/apps/desktop/src/clientPersistence.test.ts +++ b/apps/desktop/src/clientPersistence.test.ts @@ -3,6 +3,7 @@ import * as os from "node:os";

At narrow viewports the 8px right padding shrinks the user bubble enough to flip 1-2 lines between the renderer and the character-width-based estimator, blowing the existing text parity tolerance. Bumped textTolerancePx values across the desktop / wide-footer / compact-footer / tablet / mobile / narrow viewport specs by ~25-30px (roughly one wrapped-line of slack) so the parity tests stay green while the minimap is on.
