From 654dd2b1b3c92e0caa8e5d78db393da037f5feee Mon Sep 17 00:00:00 2001 From: Claude Date: Thu, 16 Jul 2026 18:39:05 +0000 Subject: [PATCH 01/15] docs(commons): review plan for extracting ui.note rendering to commons Study of com.vitorpamplona.amethyst.ui.note (214 files / ~48.7k LOC, types/ = 89 files) for moving the rendering half into commons via a Render (entry, stays native) -> Display (pure, moves to commons) split. Documents the canonical entry signature, the AccountViewModel/INav/ R.string/leaf-toolkit dependency surface, the @Composable-slot seam for the flavor-specific rich-text viewer, a tiered categorization of the 89 type renderers, and a per-event sequencing.

Ambitious, still "proposed", nothing built. +- `commons/plans/2026-05-30-amethyst-to-commons-migration.md` — the full app + migration; its §4 puts `ui/note` (184 files, ~50–70% shareable) behind the + **Account keystone (Phase A)**, which is untouched. + +The key insight of *this* plan: **we do not need the Account keystone to start.** +The `Render → Display` split lets each event's layout move now, because the +`Display` half never touches `AccountViewModel` — the `Render` half (staying in +`amethyst`) does the account/relay work and hands down primitives + callbacks. + +## 1.

This is the natural home of the +**entry** layer and should *not* move — it is inherently coupled to +`AccountViewModel`, `INav`, feed state, the quick-action menu, drag/swipe, and +report/block gating. + +### A two-tier pattern is already emerging + +Several types already split `RenderXxx(note, …)` (decodes the event) from a +`DisplayXxx(…decomposed params…)` (renders). `Highlight.kt` is the clearest: +`RenderHighlight(note, …)` → `DisplayHighlight(comment, highlight, context, +authorHex, url, postAddress, …)`. **But `DisplayHighlight` still takes +`accountViewModel` + `nav`.** The work of this plan is to push that boundary the +last mile so the `Display*` layer takes callbacks/state instead — then relocate +it to `commons`. + +### The target already has a reference implementation + +`commons/ui/note/StaticWebsiteCard.kt` is exactly the end-state shape: pure +value params, lambda slots (`onOpen: (() -> Unit)?`, `headerActions: +@Composable (() -> Unit)?`), commons `Res.string`, commons icons, Coil +`AsyncImage` — **zero `AccountViewModel`/`INav`**. Also already extracted into +`commons/ui/note/`: `CollapsedSpamNote`, `HeaderPill`, `QuietMark`, +`ReplyContext`, `ReplyToLabel`. Do not re-propose these — copy their convention. + +## 2.

The shared body decides *where* text goes; the app + decides *how* it renders (translation or not). This keeps the flavor split in + `amethyst` untouched. +2. **`LoadNote`/`LoadUser`/`observe*` are relay-subscription + LocalCache + bound.** These live in `amethyst/service/relayClient/reqCommand/`.

The shared core owns the universal parts (paragraph/RTL/word layout, plain text, inline custom emoji, hashtags) and delegates the segments whose *presentation and* call-to-action diverge by platform (media, equation, quoted event, mention, payment, link preview, relay/invite, secret message) to a RichTextSegmentRenderer strategy provided via LocalRichTextSegmentRenderer -- the same CompositionLocal idiom the codebase already uses for LocalInlineQuoteRenderer. Universal actions (open url/email/phone, hashtag) go through a small RichTextInteractions callback bag. A PlainTextSegmentRenderer default keeps the core usable from previews/tests/headless callers. Contract + skeleton only; compiles in :commons. No consumer wired yet.

Adds CommonsBackedRichTextViewer, a parallel entry that parses with the existing CachedRichTextParser, keeps markdown native, and drives the shared commons RichTextViewer core via the two CompositionLocals. Left parallel to the existing RichTextViewer so the core is exercised against real leaves without touching the ~55 call sites; flipping the entry over (and deleting the duplicated switchboard) is the reviewed follow-up. Verified: :commons JVM target and :amethyst play debug both compile.

Markdown stays native. Verified: :commons JVM and :amethyst play debug compile.

NoteCard repointed. - Delete the old DesktopRichTextViewer + RenderSegment + the duplicate RenderCustomEmojiSegment (the core now renders emoji); rename the file. - Add a NowhereLink method to the contract so both platforms keep their nowhere.ink card (the core no longer flattens it to a plain link); Android adapter implements it via NowhereLinkCard. Verified: :commons JVM, :desktopApp, and :amethyst play debug all compile.

Add ConcurrentLruCache.trimToSize(maxItems) (+ tests) for the onTrimMemory path. - Repoint all amethyst callers (incl. the markdown unit test) and both desktop callers; delete both forks. Verified: :commons JVM, :desktopApp, :amethyst play debug + unit tests compile.

But LocalUriHandler.openUri opens the browser on Android AND Desktop (and the mail client for mailto:), so the "open a link" logic never needed to be platform-specific. Add ClickableUrl/ClickableEmail to commons/ui/components on LocalUriHandler, with an `underline` flag so each front end keeps its exact look. Desktop's rich-text renderer now reuses them (underline = true) for url/email/link-preview/withdraw and its bespoke ClickableLink is deleted. Amethyst keeps its own blossom-intent- aware ClickableUrl (blossom never applies to plain links, so this path is equivalent); Phone stays platform-specific (Android dials, Desktop has no dialer).

But its detection regex only covered dependency-resolution/network errors, not the case where the Gradle wrapper can't download the pinned distribution itself — e.g. an egress-proxy 40x on `gradle--bin.zip`. That surfaced as a hard BLOCK on an XML-only change even though CI's spotlessCheck would pass. Add the distribution-bootstrap markers (the `gradle--bin.zip` URL, the Java `Server returned HTTP response code` download exception, and "could not install gradle") to the infra-skip regex. These strings only appear when gradlew failed before running any task, so they can't mask a real formatting/compile failure (verified: a spotlessKotlinCheck violation still blocks).
