Mandelbrot: fill display with image view + regenerate GIF with Kitty graphics#5511
Merged
Conversation
The previous capture forced the Sixel raster protocol because agg could not render Kitty graphics. tuirec v0.9.0 now defaults to Kitty graphics and its pinned agg (v1.11.0-sixel, built on a Kitty-capable avt) renders them, so the Mandelbrot scenario records through its preferred Kitty path. Recorded with the released tuirec + auto-downloaded agg. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Anchor the MandelbrotImageView at (0,0) and size it Dim.Fill() so the fractal fills the whole display region instead of a small centered box, and move the status label to the bottom edge. Re-record the docfx GIF with a smoother tour: a multi-step zoom into the seahorse valley, a pan across the seahorse filaments, and a zoom back out — demonstrating the smooth zooming and panning the larger image view makes possible.

changed the title
tuirec v0.9.0 advertises a Kitty identity by default, so raster apps (Mandelbrot, Images) now record via Kitty graphics, which agg v1.11.0-sixel renders. Add a 'Raster graphics' section covering protocol selection, how to confirm which protocol the cast captured, that the #84 cell-size mismatch is sixel-only, and a smooth zoom/pan recording tip. Update the validation checklist and troubleshooting for Kitty + sixel.
Capture the precise keystroke tour, flags, and the design rationale (seahorse-valley target coords, center-anchored keyboard zoom, the span ~1.0 / 80-iteration black-out limit, fill layout) so a future agent can reproduce the hero GIF in one shot instead of re-deriving it.
Address feedback from an agent that ran the guide on Linux: - Add bash equivalents alongside PowerShell for the raster recipes, validation greps, and error check (the raster recipes are Linux/macOS only, but every snippet was PowerShell). Make the Mandelbrot recipe bash-primary. - Add a fresh-container bootstrap (dotnet SDK matching global.json, Go install, PATH for ~/.dotnet and GOPATH/bin) and fix the Windows-only GOPATH PATH note. - Give a python3/Pillow one-liner to extract a mid-zoom frame, plus the expected readout (Center X ~ -0.74, Y ~ 0.105, Span ~ 1.0) so the spot-check measures a landmark instead of a vibe. - Soften exact payload counts to robust invariants (thousands of Kitty, zero sixel, ~0.9 MB) since the count drifts with timing/font-size. - Note the '#84 font-size adjust' log line is expected and auto-corrected in v0.9.0, harmless for the Kitty path.

Cull fully occluded overlapped opaque subviews during draw DrawSubViews() now skips drawing an Overlapped sibling when it is entirely covered by the higher-Z opaque peers already drawn. Such a sibling produces no visible output — every cell it would draw, including its own RenderLineCanvas, is clipped away by the clip "holes" those peers punched in DoDrawComplete — so skipping its Draw is output-neutral. The culled view's NeedsDraw is cleared (mirroring a drawn-but-fully-clipped pass) so it does not keep the SuperView perpetually dirty. Culling is intentionally conservative — it only applies to a candidate that is itself Overlapped, opaque (content/Border/Padding not Transparent), without a Margin shadow, and NOT SuperViewRendersLineCanvas. The last guard is what keeps Tabs correct: tab pages render their borders (and headers) through the SuperView's LineCanvas painters'-algorithm composition, so they must never be culled or their header line art would be dropped. The whole check is gated on the presence of an Overlapped sibling, keeping the common non-overlapping draw path zero-overhead. Opaque coverage is the region inside a view's (transparent-by-default) Margin — the Border frame — which matches the area DoDrawComplete excludes from the clip. Adds OcclusionCullingTests covering: fully-occluded cull, NeedsDraw clearing, partial coverage, transparent occluder, transparent candidate, shadowed candidate, SuperViewRendersLineCanvas candidate, non-Overlapped candidate, the no-Overlapped-siblings gate, output-neutrality, and a Tabs regression that inactive pages are never culled. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * Address review: don't cull TransparentMouse candidates The cull path skips Draw()/DoDrawComplete(), which repopulates a view's CachedDrawnRegion for ViewportSettingsFlags.TransparentMouse layers. That region is invalidated by SetNeedsDraw(), so culling an opaque TransparentMouse view left it with a null cache and dropped it from mouse hit-testing (GetViewsUnderLocation blanket-removes TransparentMouse views with a null cache) — a state divergence from the drawn-but-clipped path the cull is meant to mirror. Add ParticipatesInTransparentMouseHitTesting() and exclude such candidates: the view's own ViewportSettings, plus any adornment that is TransparentMouse with non-empty Thickness (adornment caches survive SetNeedsDraw(), but the first draw must still populate a thick transparent-mouse adornment's cache). Margin is TransparentMouse by default, so this only excludes views with an actual Margin thickness — the common empty-margin overlapped view is still culled. Adds regression tests: TransparentMouseCandidate_IsNotCulled_AndKeepsHitRegion (fails without the guard — CachedDrawnRegion is null) and TransparentMouseMarginCandidate_IsNotCulled.

The lint immediately caught a stale .NET SDK 8.0 claim in CONTRIBUTING.md, now fixed. - Wire tuirec into agent entry points (CLAUDE.md, AGENTS.md, build-app.md): agents can verify TUI behavior by recording with tuirec and reading the asciinema .cast output back as text, per Scripts/tuirec/README.md. - Promote durable guidance from machine-specific .claude/projects/ memory files into shared rules (.claude/rules/logging-tracing.md and fragile-areas.md); untrack .claude/projects/ and gitignore it (the directory name encoded a local user path). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Document Windows ConPTY sixel limitation in tuirec README Discovered while verifying the About Box fire animation: ConPTY strips sixel DCS and the DA1 sixel handshake, so sixel content cannot be captured in tuirec recordings on Windows (apps detect Sixel support: False). Added to the troubleshooting table and validation checklist so the next agent does not burn recordings rediscovering it. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * tuirec README: require measuring grid-anchored sixels, not eyeballing Agents (including me) recurrently verify the wrong invariant when checking sixel recordings: confirming the sixel appears, or that agg rendered it faithfully at the requested cursor cell, and calling it done. That misses size/position errors — notably the ~4% undersize from tuirec advertising a cell resolution that does not match agg's rendered font cell (tuirec #84). Adds a "Verifying Placement and Size (measure - don't eyeball)" section with the cell-calibration recipe (measure agg's real cell from a known grid reference; reconcile against the resolution the app used; confirm the rendered bbox covers the target region), a checklist item, a troubleshooting row for #84, and rewrites the workflow's "visual confirm" step to require measurement for grid-anchored content. Also states the general principle: verify the invariant the change was meant to satisfy, not a proxy. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Sync CONTRIBUTING.md TFM to net10.0; lint stale TFMs Codex review on #5478 flagged that build-test-workflow.md cites CONTRIBUTING.md as its source of truth, but CONTRIBUTING.md still described the project as net8.0 (line 28) even though the Required Tools section was updated to .NET 10 — so the declared source could revert the fix and mislead readers onto the wrong toolchain. Test-first: added Rule 6 to lint-agent-docs.ps1 that derives the expected target-framework moniker from global.json's SDK major and fails on any mismatched `net<major>.0` reference. It flagged CONTRIBUTING.md:28 (net8.0); fixed that to `C# 14 (net10.0)`. Lint now passes (32 files). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> --------- Co-authored-by: Claude Fable 5 <noreply@anthropic.com> * Adds doc snippet compile validation; fixes v1 API rot in agent docs (#5480) * Add doc snippet compile validation with obsolete-API rejection Roslyn-based validator that compiles every fenced C# block in the agent docs (ai-v2-primer.md, build-app.md, common-patterns.md) against the built Terminal.Gui assembly, so example rot fails CI instead of misleading readers. Statement fragments are wrapped in a Runnable<string?> harness; blocks marked WRONG / `snippet: ignore` are skipped. Obsolete-API use (CS0618/CS0612) is treated as a failure, not a warning, so v1 rot like the legacy static Application.Init cannot pass as "compiled". testdata/obsolete-api.md + a CI negative-test step assert the validator rejects obsolete APIs. The check caught real rot fixed here: two cookbook snippets used the obsolete TextView (now a plain content View, pointing at gui-cs/Editor's EditorView). Result: 29 compiled, 1 skipped, 0 failed; negative test green. Rebased onto develop after #5478 merged (squash), keeping only this PR's files; no overlap with the merged agent-docs lint changes. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Fix Validate Doc Snippets CI: full history for GitVersion The workflow built Terminal.Gui without fetch-depth:0, so GitVersion.MsBuild failed on the shallow clone ("Repository is a shallow clone"). Match the build-validation workflow's checkout (fetch-depth: 0). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> --------- Co-authored-by: Claude Fable 5 <noreply@anthropic.com> * Notify gui-cs/Editor on NuGet publish (#5483) Dispatches `terminal-gui-published` (payload: the published SemVer) to gui-cs/Editor after each publish. Editor's bump-terminal-gui.yml picks it up, pins the new version, validates with its full test suites, and republishes Editor against it - making Editor a continuous canary for TG API churn (see Editor specs/decisions.md DEC-010). No-op until an EDITOR_DISPATCH_TOKEN secret (PAT with repo scope on gui-cs/Editor) is configured; Editor also polls NuGet on a 6h schedule as a fallback, so nothing breaks without it. Co-authored-by: Claude Fable 5 <noreply@anthropic.com> * Fix publish.yml: secrets context is invalid in step if conditions The Editor-notify guard from #5483 used `if: secrets.X != ''`, which is not an available context for step ifs and invalidated the whole workflow (publish run 27422643812). Mirror the secret into job-level env and gate on that, same pattern as the TEMPLATE/clet dispatches in gui-cs/Editor.

Obsolete-API use (CS0618/CS0612) is treated as a failure, not a warning, so v1 rot like the legacy static Application.Init cannot pass as "compiled". testdata/obsolete-api.md + a CI negative-test step assert the validator rejects obsolete APIs. The check caught real rot fixed here: two cookbook snippets used the obsolete TextView (now a plain content View, pointing at gui-cs/Editor's EditorView). Result: 29 compiled, 1 skipped, 0 failed; negative test green. Rebased onto develop after #5478 merged (squash), keeping only this PR's files; no overlap with the merged agent-docs lint changes. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Fix Validate Doc Snippets CI: full history for GitVersion The workflow built Terminal.Gui without fetch-depth:0, so GitVersion.MsBuild failed on the shallow clone ("Repository is a shallow clone"). Match the build-validation workflow's checkout (fetch-depth: 0). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> --------- Co-authored-by: Claude Fable 5 <noreply@anthropic.com> * Notify gui-cs/Editor on NuGet publish (#5483) Dispatches `terminal-gui-published` (payload: the published SemVer) to gui-cs/Editor after each publish. Editor's bump-terminal-gui.yml picks it up, pins the new version, validates with its full test suites, and republishes Editor against it - making Editor a continuous canary for TG API churn (see Editor specs/decisions.md DEC-010). No-op until an EDITOR_DISPATCH_TOKEN secret (PAT with repo scope on gui-cs/Editor) is configured; Editor also polls NuGet on a 6h schedule as a fallback, so nothing breaks without it. Co-authored-by: Claude Fable 5 <noreply@anthropic.com> * Fix publish.yml: secrets context is invalid in step if conditions The Editor-notify guard from #5483 used `if: secrets.X != ''`, which is not an available context for step ifs and invalidated the whole workflow (publish run 27422643812). Mirror the secret into job-level env and gate on that, same pattern as the TEMPLATE/clet dispatches in gui-cs/Editor.

Re-record the docfx GIF with a smoother tour: a multi-step zoom into the seahorse valley, a pan across the seahorse filaments, and a zoom back out — demonstrating the smooth zooming and panning the larger image view makes possible. * Scripts/tuirec: document Kitty graphics as the default raster path tuirec v0.9.0 advertises a Kitty identity by default, so raster apps (Mandelbrot, Images) now record via Kitty graphics, which agg v1.11.0-sixel renders. Add a 'Raster graphics' section covering protocol selection, how to confirm which protocol the cast captured, that the #84 cell-size mismatch is sixel-only, and a smooth zoom/pan recording tip. Update the validation checklist and troubleshooting for Kitty + sixel. * Scripts/tuirec: add exact one-shot recipe for Mandelbrot.gif Capture the precise keystroke tour, flags, and the design rationale (seahorse-valley target coords, center-anchored keyboard zoom, the span ~1.0 / 80-iteration black-out limit, fill layout) so a future agent can reproduce the hero GIF in one shot instead of re-deriving it. * Scripts/tuirec: cross-platform commands + runnable verification Address feedback from an agent that ran the guide on Linux: - Add bash equivalents alongside PowerShell for the raster recipes, validation greps, and error check (the raster recipes are Linux/macOS only, but every snippet was PowerShell). Make the Mandelbrot recipe bash-primary. - Add a fresh-container bootstrap (dotnet SDK matching global.json, Go install, PATH for ~/.dotnet and GOPATH/bin) and fix the Windows-only GOPATH PATH note. - Give a python3/Pillow one-liner to extract a mid-zoom frame, plus the expected readout (Center X ~ -0.74, Y ~ 0.105, Span ~ 1.0) so the spot-check measures a landmark instead of a vibe. - Soften exact payload counts to robust invariants (thousands of Kitty, zero sixel, ~0.9 MB) since the count drifts with timing/font-size. - Note the '#84 font-size adjust' log line is expected and auto-corrected in v0.9.0, harmless for the Kitty path. --------- Co-authored-by: Claude Opus 4.8 (1M context) <noreply@anthropic.com> --------- Signed-off-by: dependabot[bot] <support@github.com> Co-authored-by: Kevin Harder <kevin@kevinharder.com> Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Co-authored-by: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Co-authored-by: dependabot[bot] <49699333+dependabot[bot]@users.noreply.github.com>

Two related changes to the Mandelbrot scenario and its docfx hero GIF.
1. Scenario layout
MandelbrotImageViewis now anchored atX=0, Y=0withWidth=Dim.Fill(),Height=Dim.Fill()so the fractal fills the whole display region instead of a small centered30×20box. The status label moves to the bottom edge. The larger image view makes smooth zooming and panning far more legible.2. Regenerated GIF (Kitty graphics + smoother tour)
The previous capture forced Sixel because agg could not render Kitty graphics. That's now fixed end-to-end (tig/avt → tig/agg
v1.11.0-sixel→ gui-cs/tuirecv0.9.0, which defaults to Kitty graphics). Recorded with the releasedtuirec v0.9.0(auto-downloaded the releasedagg v1.11.0-sixel); the cast holds ~8900 Kitty graphics payloads and no sixel image data.The tour now demonstrates smooth motion: a multi-step zoom from the full set into the seahorse valley, a pan across the seahorse filaments, then a zoom back out and reset.
Also updates the image alt text (sixel → Kitty graphics).
