TLDR

Every docs page with a feature to show now opens on a narrated film of the real extension, captioned in en/ja/zh. Three bugs the filming exposed are fixed test-first.

Details

Films. There are 14 new films, and the leak film is reshot with narration. Each is published as MP4 (AAC) and WebM (Opus) in LFS, with a WebP poster and .en/.ja/.zh.vtt captions. Each is catalogued in videos.json and placed after its page's introduction in all three languages:

Page	Film	Length
Getting Started	getting-started (replaces sharplsp-tour on this page; the blog keeps it)	1:04
Editor Setup	editor-setup	0:41
Configuration	configuration: sharplsp.toml with monorepo mode → SLSPC0101	0:51
F# Language Support	fsharp-language (the page also keeps profiler-fsharp)	1:53
Code Completions	code-completions	1:09
Hover	hover	1:15
Go to Definition	navigation	1:00
Diagnostics	diagnostics	1:24
Refactoring	refactoring	1:27
Context Menus	context-menus	1:10
NuGet	nuget (installs FsToolkit.ErrorHandling into the F# project)	1:18
Profiler	profiler-csharp (replaces profiler-film at the top; home and blog keep it)	2:16
Fix a Memory Leak	profiler-fix-memory-leak, now narrated and on the layered retention graph	1:32
Architecture	architecture: the host log routing an F# hover to FCS and a C# hover to Roslyn, then tree-sitter folding	0:38
Contributing	contributing	0:38

The Zed page has no film. Filming a native Metal app would mean recording the real desktop through OS permissions. [WEB-DESIGN-MEDIA] now says so.

The language films run on the new demos/Shop.slnx, which holds the C# Storefront and the F# FsStorefront in one solution. F# is shown first. Catalog.Generate gains an XML doc comment for the hover film.

Bug fixes (each with a failing test first).

• FSharpProjectLoading.buildProjectOptions passed every source file to GetProjectOptionsFromCommandLineArgs and also set SourceFiles. FCS compiled each file twice, so every single-target F# project without a C# reference showed FS3551 ("already appeared in the compilation list") on every source. Sources now go in SourceFiles only.
• sort_members::build_edits copied each member's leading blank lines and also added its own separators, which left two or three blank lines between members. The reordered text is now built by reordered_text/leading_layout. A type whose members are separated by blank lines keeps exactly one between each; a compact type stays compact, with one blank line only where a new accessibility/category group starts. CRLF is preserved.
• NuGet browser buildDetailsHtml: the version picker beside Install selected nothing, so it showed the newest listed version (often a prerelease such as 6.0.0-beta003), while Install sends the search result's stable version. It now shows installedVersion ?? version.

Film kit (src/website/tools/profiler-film/, see its README).

• New acts:
  • kit/acts/language.mjs: LANGUAGE settings, prepareCode/warm, scene(clip, step, caption, act, { speed, retries }), complete, quickFix, renameTo, navigate (fails the take on "No definition found"), peekReferences, hoverEach, settingsEditor;
  • kit/acts/shop.mjs: moves on the Shop demo shared by several films, plus ready(...);
  • kit/acts/explorer.mjs: Solution Explorer context menus;
  • kit/acts/tour.mjs: profilerTour, now used by both profiler films;
  • kit/code.mjs: finds a word on a line on screen, and hovers or clicks it.
• overlay.pointAt: a pointer that glides to what the film acts on. Stills hide it, as they hide the caption.
• Sets: SHOP, and REPO (a git archive of HEAD and lspkit, opened with the extension disabled). A film can supply its own workspace settings. A failed shoot copies the editor's logs to out/<film>/logs.
• Privacy:
  • demos, the editor profile and temp files live under /tmp;
  • the editor runs with --force-disable-user-env, on a copy-on-write clone of the .NET install at /tmp/sharplsp-film-dotnet, so the SDK path and any command a terminal prints are neutral;
  • the demo app shares that temp folder, so the profiler can still attach;
  • context menus render in the workbench (window.menuStyle: custom).
• voice.mjs loads kokoro-js only when it speaks. Its phonemizer used to print its own source over any failed shoot.
• [WEB-DESIGN-MEDIA] covers the language films, the narrated walkthrough on every page, and when a terminal may appear: F# Interactive, a build task, or a shell with no profile and a bare $ prompt.

Docs. The architecture page (en/ja/zh) now says a restarted sidecar does not yet reload its workspace (#386).

Issues filed for bugs found but not fixed here: #386 (restarted sidecar not rehydrated), #387 (F# F12 on a module-qualified call right after load), #388 (F# hover lacks .NET XML docs), #389 (F# inlay-hint layout), #390 (no DiagnosticTag.Unnecessary), #391 (metadata as source decompiles reference assemblies).

How Do The Automated Tests Prove It Works?

• F#, double compile: FSharpProjectCrackingTests › hand-built options name each source once, so FCS never sees a file twice failed before the fix (the source was in OtherOptions). It now passes. It also checks the project with ParseAndCheckProject and asserts no FS3551 and no diagnostics at all. The full F# sidecar suite passes, 440/440.
• F# navigation coverage: FSharpNavigationEdgeTests › definition of a module-qualified call lands in the declaring file the editor never opened (passes; F#: Go to Definition on Checkout.checkout finds nothing until Checkout.fs has been opened #387 still needs the editor's fresh-session state reproduced).
• Sort Members: sort_members_extra › test_sort_members_keeps_one_blank_line_between_members and test_sort_members_keeps_compact_members_compact both failed before the fix ("\n\n\n\n"; blank lines added to a compact type) and now pass. All 16 sort-members e2e tests and the 6 unit tests pass, and clippy is clean.
• NuGet: NuGet Browser — pure html › buildHtml details panel shows the version Install installs, not the newest prerelease failed before the fix ("the picker shows the version Install sends") and now passes (20/20). npm run lint passes: prettier, eslint and tsc.
• Website: all of npx playwright test passes locally: 604 passed and 11 skipped, the skips by layout.
  • site-videos.spec.js, every docs page in every language:
    • plays its film, served with a poster;
    • carries a VideoObject that matches the player's label;
    • plays the film unmuted, with en/ja/zh text/vtt tracks and the page's language as default;
    • never autoplays.
  • profiler-media.spec.js: the Profiler page now opens on the profiler-csharp poster.
• Duplication: deslop . reports 6.5% (6.6% before), under the 6.65% threshold.
