From c4b3b28932d9c0c47aace9b8845645ccf2db0ec2 Mon Sep 17 00:00:00 2001 From: Gordon Woodhull Date: Tue, 17 Feb 2026 09:40:20 -0500 Subject: [PATCH 01/30] Implement project metadata merging with format resolution Add resolve_format_config() to extract format-specific settings from metadata. This enables proper merging of _quarto.yml settings with document frontmatter, where format.html.* settings override top-level settings when rendering to HTML. Changes: - New quarto-config/src/format.rs with resolve_format_config() function - ProjectConfig stores full metadata as ConfigValue (replaces raw + format_config) - AstTransformsStage flattens both project and document metadata for target format - TocGenerateTransform reads from ast.meta instead of format metadata - WASM updated to use ProjectConfig::with_metadata() Merge precedence (lowest to highest): 1. Project top-level settings 2. Project format-specific settings (format.{target}.*) 3. Document top-level settings 4. Document format-specific settings (format.{target}.*) Includes unit tests for format resolution and integration tests for metadata merging in AstTransformsStage. --- Cargo.lock | 2 + .../2026-02-16-project-metadata-merging.md | 602 ++++++++++++++++++ crates/quarto-config/src/format.rs | 413 ++++++++++++ crates/quarto-config/src/lib.rs | 3 + crates/quarto-core/Cargo.toml | 2 + crates/quarto-core/src/project.rs | 87 ++- .../src/stage/stages/ast_transforms.rs | 352 +++++++++- .../src/transforms/toc_generate.rs | 120 ++-- .../metadata/doc-overrides/_quarto.yml | 2 + .../doc-overrides/overrides-title.qmd | 13 + .../metadata/format-specific/_quarto.yml | 8 + .../format-specific/doc-format-overrides.qmd | 22 + .../format-specific/format-html-toc.qmd | 24 + .../metadata/project-inherits/_quarto.yml | 2 + .../project-inherits/inherits-title.qmd | 12 + crates/wasm-quarto-hub-client/src/lib.rs | 6 +- 16 files changed, 1575 insertions(+), 95 deletions(-) create mode 100644 claude-notes/plans/2026-02-16-project-metadata-merging.md create mode 100644 crates/quarto-config/src/format.rs create mode 100644 crates/quarto/tests/smoke-all/metadata/doc-overrides/_quarto.yml create mode 100644 crates/quarto/tests/smoke-all/metadata/doc-overrides/overrides-title.qmd create mode 100644 crates/quarto/tests/smoke-all/metadata/format-specific/_quarto.yml create mode 100644 crates/quarto/tests/smoke-all/metadata/format-specific/doc-format-overrides.qmd create mode 100644 crates/quarto/tests/smoke-all/metadata/format-specific/format-html-toc.qmd create mode 100644 crates/quarto/tests/smoke-all/metadata/project-inherits/_quarto.yml create mode 100644 crates/quarto/tests/smoke-all/metadata/project-inherits/inherits-title.qmd diff --git a/Cargo.lock b/Cargo.lock index c3bbc8c3..ce092f77 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -3276,6 +3276,7 @@ dependencies = [ "quarto-source-map", "quarto-system-runtime", "quarto-util", + "quarto-yaml", "regex", "runtimelib", "serde", @@ -3288,6 +3289,7 @@ dependencies = [ "tracing", "uuid", "which 8.0.0", + "yaml-rust2", ] [[package]] diff --git a/claude-notes/plans/2026-02-16-project-metadata-merging.md b/claude-notes/plans/2026-02-16-project-metadata-merging.md new file mode 100644 index 00000000..2328a572 --- /dev/null +++ b/claude-notes/plans/2026-02-16-project-metadata-merging.md @@ -0,0 +1,602 @@ +# Project Metadata Merging with Format Resolution + +**Date**: 2026-02-16 +**Status**: Complete + +## Overview + +Implement full project metadata merging in q2, where `_quarto.yml` is parsed as `ConfigValue` and merged with document frontmatter.

Keeps `yaml_to_config_value` generic without format-specific knowledge +4. `ConfigValue::from_path()` already demonstrates creating nested structures programmatically + +### Q3: Default Format Settings ✅ RESOLVED + +Quarto 1 has built-in defaults per format (e.g., `htmlFormat()` sets `fig-width: 7`). + +**Finding**: q2 has TWO types of defaults: + +1. **Template defaults** (exist): `compute_template_defaults()` in `pampa/src/template/config_merge.rs:166-186` + - `lang: "en"` (always) + - `pagetitle` derived from `title` + - These ARE already merged as lowest-priority layer in `merged_metadata_to_context()` + +2. **Format-specific defaults** (do NOT exist): `Format::html()` etc. in `quarto-core/src/format.rs:116-143` + - `metadata: serde_json::Value::Null` - no defaults set + - Unlike Quarto 1's `htmlFormat()` which sets `fig-width: 7`, etc. + +**Decision**: For this PR, we don't need to implement format-specific defaults. The template defaults are already handled separately in the template rendering path. Format-specific defaults (like `fig-width`) can be added in a future PR if needed - they would be the lowest-priority layer before project config. + +### Q4: Backwards Compatibility ✅ RESOLVED + +The `raw: serde_json::Value` field is used elsewhere. Need to: +- Audit all usages of `ProjectConfig.raw` +- Decide: keep both fields, or migrate all usages? + +**Finding**: `raw` is only defined and assigned in `project.rs:80,334`.

Directory metadata is discovered by walking from project root to document's parent directory. Core implementation: - Add directory_metadata_for_document() in project.rs - Walk directory hierarchy, parse _metadata.yml files - Support both .yml and .yaml extensions - Return layers in root-to-leaf order for merging - Resolve relative paths in _metadata.yml against their source directory Merge integration: - Update ast_transforms.rs to include directory metadata - Merge order: project -> dir[0] -> dir[1] -> ... -> document - Each layer flattened for target format before merging Smoke-all tests for basic inheritance, multi-level hierarchy merging, document overrides, and path resolution. Also adds default noErrorsOrWarnings assertion to smoke-all tests (matching TS Quarto conventions) and supportPath file existence checks. --- Cargo.lock | 7 + ...2026-02-17-dir-metadata-path-resolution.md | 365 ++++++++ .../plans/2026-02-17-metadata-yml-support.md | 838 ++++++++++++++++++ crates/quarto-core/Cargo.toml | 1 + crates/quarto-core/src/project.rs | 684 ++++++++++++++ .../src/stage/stages/ast_transforms.rs | 64 +- .../src/transforms/toc_generate.rs | 6 +- .../quarto-test/src/assertions/file_exists.rs | 58 +- crates/quarto-test/src/runner.rs | 17 +- crates/quarto-test/src/spec.rs | 211 ++++- .../dir-metadata-hierarchy/_quarto.yml | 3 + .../chapters/_metadata.yml | 3 + .../chapters/intro/_metadata.yml | 3 + .../chapters/intro/deep-doc.qmd | 24 + .../dir-metadata-override/_quarto.yml | 3 + .../chapters/_metadata.yml | 3 + .../chapters/override-test.qmd | 23 + .../metadata/dir-metadata-paths/_quarto.yml | 3 + .../dir-metadata-paths/chapters/_metadata.yml | 6 + .../dir-metadata-paths/chapters/intro/doc.qmd | 22 + .../dir-metadata-paths/shared/styles.css | 2 + .../metadata/dir-metadata/_quarto.yml | 4 + .../dir-metadata/chapters/_metadata.yml | 5 + .../dir-metadata/chapters/chapter1.qmd | 24 + .../doc-overrides/overrides-title.qmd | 1 + .../format-specific/doc-format-overrides.qmd | 1 + .../format-specific/format-html-toc.qmd | 1 + .../project-inherits/inherits-title.qmd | 1 + .../smoke-all/quarto-test/basic-render.qmd | 1 + .../smoke-all/quarto-test/code-block.qmd | 1 + .../smoke-all/quarto-test/no-extra-files.qmd | 3 +- .../smoke-all/quarto-test/output-files.qmd | 3 +- 32 files changed, 2346 insertions(+), 45 deletions(-) create mode 100644 claude-notes/plans/2026-02-17-dir-metadata-path-resolution.md create mode 100644 claude-notes/plans/2026-02-17-metadata-yml-support.md create mode 100644 crates/quarto/tests/smoke-all/metadata/dir-metadata-hierarchy/_quarto.yml create mode 100644 crates/quarto/tests/smoke-all/metadata/dir-metadata-hierarchy/chapters/_metadata.yml create mode 100644 crates/quarto/tests/smoke-all/metadata/dir-metadata-hierarchy/chapters/intro/_metadata.yml create mode 100644 crates/quarto/tests/smoke-all/metadata/dir-metadata-hierarchy/chapters/intro/deep-doc.qmd create mode 100644 crates/quarto/tests/smoke-all/metadata/dir-metadata-override/_quarto.yml create mode 100644 crates/quarto/tests/smoke-all/metadata/dir-metadata-override/chapters/_metadata.yml create mode 100644 crates/quarto/tests/smoke-all/metadata/dir-metadata-override/chapters/override-test.qmd create mode 100644 crates/quarto/tests/smoke-all/metadata/dir-metadata-paths/_quarto.yml create mode 100644 crates/quarto/tests/smoke-all/metadata/dir-metadata-paths/chapters/_metadata.yml create mode 100644 crates/quarto/tests/smoke-all/metadata/dir-metadata-paths/chapters/intro/doc.qmd create mode 100644 crates/quarto/tests/smoke-all/metadata/dir-metadata-paths/shared/styles.css create mode 100644 crates/quarto/tests/smoke-all/metadata/dir-metadata/_quarto.yml create mode 100644 crates/quarto/tests/smoke-all/metadata/dir-metadata/chapters/_metadata.yml create mode 100644 crates/quarto/tests/smoke-all/metadata/dir-metadata/chapters/chapter1.qmd diff --git a/Cargo.lock b/Cargo.lock index ce092f77..e46ea40b 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -2857,6 +2857,12 @@ version = "1.0.15" source = "registry+https://github.com/rust-lang/crates.io-index" checksum = "57c0d7b74b563b49d38dae00a0c37d4d6de9b432382b2892f0574ddcae73fd0a" +[[package]] +name = "pathdiff" +version = "0.2.3" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "df94ce210e5bc13cb6651479fa48d14f601d9858cfe0467f43ae157023b938d3" + [[package]] name = "pem" version = "3.0.6" @@ -3265,6 +3271,7 @@ dependencies = [ "include_dir", "jupyter-protocol", "pampa", + "pathdiff", "pollster", "quarto-analysis", "quarto-ast-reconcile", diff --git a/claude-notes/plans/2026-02-17-dir-metadata-path-resolution.md b/claude-notes/plans/2026-02-17-dir-metadata-path-resolution.md new file mode 100644 index 00000000..e7e1078e --- /dev/null +++ b/claude-notes/plans/2026-02-17-dir-metadata-path-resolution.md @@ -0,0 +1,365 @@ +# Directory Metadata Path Resolution + +**Date**: 2026-02-17 +**Status**: Complete +**Depends on**: `2026-02-17-metadata-yml-support.md` (Complete) + +## Completion Summary + +All phases implemented successfully: + +- [x] **Phase 1: Unit Tests** - 7 tests in `directory_metadata_tests` module +- [x] **Phase 2: Core Implementation** - `adjust_paths_to_document_dir()` function +- [x] **Phase 3: Integration** - Called from `directory_metadata_for_document()` +- [x] **Phase 4: Integration Tests** - `smoke-all/metadata/dir-metadata-paths/` + +### Key Implementation Details + +1.

This plan implements that missing piece. + +### What is ConfigValue? + +`ConfigValue` (defined in `crates/quarto-pandoc-types/src/config_value.rs`) is q2's representation of YAML configuration: + +```rust +pub struct ConfigValue { + pub value: ConfigValueKind, // The actual value + pub source_info: SourceInfo, // Where it came from + pub merge_op: MergeOp, // How to merge with other layers +} + +pub enum ConfigValueKind { + Scalar(Yaml), // Plain strings, ints, bools, etc. - NOT paths + PandocInlines(Inlines), // Markdown inline content + PandocBlocks(Blocks), // Markdown block content + Path(String), // Explicitly tagged as a path with !path + Glob(String), // Glob pattern with !glob + Expr(String), // Runtime expression with !expr + Array(Vec), // Array of values + Map(Vec), // Map with ConfigMapEntry { key, key_source, value } +} +``` + +**Key insight**: Only `ConfigValueKind::Path(String)` values need adjustment. Plain strings in `Scalar(Yaml::String(...))` are left alone. + +### What are `!path` tags? + +In YAML, `!path` is a custom tag that marks a value as a file path: + +```yaml +# In _metadata.yml +css: !path ./styles.css # Parsed as ConfigValueKind::Path +bibliography: !path ../refs.bib # Parsed as ConfigValueKind::Path +theme: cosmo # Parsed as ConfigValueKind::String (NOT adjusted) +``` + +The `quarto_yaml` crate handles parsing these tags.

From 9b9970a9f7f5aa7f951206a5d764a5defeef606f Mon Sep 17 00:00:00 2001 From: Gordon Woodhull Date: Wed, 4 Mar 2026 17:21:45 -0500 Subject: [PATCH 05/30] Add WASM smoke-all test runner for hub-client Vitest-based test runner that exercises all 15 smoke-all fixtures through the WASM rendering pipeline, verifying feature parity with the native Rust test runner. Implements all assertion types: ensureFileRegexMatches, ensureHtmlElements (via jsdom), noErrors, noErrorsOrWarnings, shouldError, and printsMessage. Filesystem assertions (fileExists, folderExists, pathDoesNotExist) are parsed but treated as no-ops in WASM context. One skip: expected-error.qmd's printsMessage check is bypassed because WASM formats the error message differently than native render_to_file. The shouldError assertion still runs for that fixture. Adds `yaml` devDependency for frontmatter parsing. --- .../plans/2026-02-19-wasm-smoke-all-tests.md | 180 ++++++ hub-client/package.json | 3 +- hub-client/src/services/smokeAll.wasm.test.ts | 551 ++++++++++++++++++ package-lock.json | 55 +- 4 files changed, 762 insertions(+), 27 deletions(-) create mode 100644 claude-notes/plans/2026-02-19-wasm-smoke-all-tests.md create mode 100644 hub-client/src/services/smokeAll.wasm.test.ts diff --git a/claude-notes/plans/2026-02-19-wasm-smoke-all-tests.md b/claude-notes/plans/2026-02-19-wasm-smoke-all-tests.md new file mode 100644 index 00000000..4d208d63 --- /dev/null +++ b/claude-notes/plans/2026-02-19-wasm-smoke-all-tests.md @@ -0,0 +1,180 @@ +# WASM Smoke-All Test Runner (TypeScript) + +## Overview + +Create a vitest-based test runner that exercises the WASM rendering module against the same smoke-all test fixtures used by the native Rust test runner.

Key functions: + - `render_qmd(path: &str) -> Promise` — Renders a QMD file from VFS. Returns JSON: `{ "success": true, "html": "...", "warnings": [...] }` or `{ "success": false, "error": "...", "diagnostics": [...] }` + - `vfs_add_file(path: &str, content: &str)` — Add a text file to VFS + - `vfs_clear()` — Clear user files from VFS (preserves embedded resources) + - `vfs_list_files()` — List all VFS files (returns JSON array) + - All VFS paths use the `/project/` prefix (e.g., `/project/_quarto.yml`, `/project/chapters/doc.qmd`) + +### Existing WASM test patterns +- **`hub-client/src/services/projectContext.wasm.test.ts`** — Best example to follow: loads WASM module, populates VFS with `vfs_add_file`, calls `render_qmd`, and asserts on HTML output. Demonstrates VFS clear/populate/render cycle. +- **`hub-client/src/services/changelogRender.wasm.test.ts`** — Another WASM test example (simpler, no VFS population). +- **`hub-client/vitest.wasm.config.ts`** — Vitest config for WASM tests. Matches `src/**/*.wasm.test.ts`, uses `environment: 'node'`, 30-second timeout. Run with `npm run test:wasm`. + +### Smoke-all test fixtures +- **`crates/quarto/tests/smoke-all/`** — The shared test fixtures. Two categories: + - `quarto-test/` — 7 basic rendering tests (callouts, code blocks, error handling, file existence) + - `metadata/` — 7 project/directory metadata test directories, each with `_quarto.yml`, possibly `_metadata.yml` files, and `.qmd` test documents + +### Test specification format +- **`crates/quarto-test/src/spec.rs`** — Rust parser for `_quarto.tests` specs (reference for the TS implementation) +- **`~/src/quarto-cli/tests/smoke/smoke-all.test.ts`** — Original TS implementation we're drawing from (Deno-based, not directly reusable) + +### Existing hub-client dependencies +- **`jsdom`** is already a dev dependency in `hub-client/package.json` — use it for `ensureHtmlElements` CSS selector queries +- **`yaml`** — **not currently in `hub-client/package.json`**. Must be added as a devDependency (`npm install -D yaml` from repo root). Needed for parsing `_quarto.tests` nested YAML from frontmatter. The `yaml` package (v2+) is the standard choice. + +## Work Items + +### Phase 0: Dependencies + +- [x] Add `yaml` package as a devDependency: run `npm install -D yaml` **from the repo root** (npm workspaces). This is needed for parsing `_quarto.tests` nested YAML from frontmatter. + +### Phase 1: Test runner infrastructure + +File: `hub-client/src/services/smokeAll.wasm.test.ts` + +- [x] WASM module initialization in `beforeAll` (follow `projectContext.wasm.test.ts` pattern — it's more relevant than `changelogRender` since it uses VFS) +- [x] `discoverTestFiles()`: use Node.js `fs` + `path` to walk `../../../crates/quarto/tests/smoke-all/**/*.qmd` relative to the test file (3 levels up from `src/services/` → `hub-client/` → repo root). Return array of absolute paths. Skip files starting with `_`. +- [x] `readFrontmatter(qmdContent: string)`: extract YAML frontmatter from QMD content (text between first `---` and second `---`). Parse with a YAML library. +- [x] `parseTestSpecs(metadata)`: extract test specs from `metadata._quarto.tests` (two levels: `metadata["_quarto"]["tests"]`). Return `{ runConfig, formatSpecs }` where each formatSpec has `{ format, assertions, checkWarnings, expectsError }`. Track `checkWarnings` as a boolean that starts `true` and is set to `false` when `noErrors`, `noErrorsOrWarnings`, or `shouldError` is encountered (matching the Rust `spec.rs` pattern). Must handle: + - `fileExists` uses object format `{ outputPath?: string, supportPath?: string }` (not bare strings) + - `printsMessage` can be a single object or an array of objects + - Unknown assertion keys must throw an error (matching both TS Quarto and Rust behavior) + - `ensureHtmlElements` uses the same two-array YAML format as `ensureFileRegexMatches`: first array = must-match selectors, second array (optional) = must-not-match selectors. Example: `ensureHtmlElements: - ["nav#TOC"]` or `ensureHtmlElements: - [] - ["nav#TOC"]`. Reuse the same array parsing logic. +- [x] `shouldSkip(runConfig)`: check `skip`, `ci`, `os`, `not_os` conditions. For WASM tests, we run on all OSes (it's platform-independent), so `os`/`not_os` checks may not apply — but implement them for compatibility. +- [x] `populateVfs(testDir, wasm)`: given a test directory (e.g., `smoke-all/metadata/project-inherits/`), find the project root (the directory containing `_quarto.yml`, or the test directory itself if no `_quarto.yml`), then recursively read all files as UTF-8 text and add them to VFS with `vfs_add_file()`. Note: `vfs_add_file` is text-only (`&str` content) — binary files in fixtures would need different handling, but current fixtures are all text. + - **Path mapping**: if the project root on disk is `/abs/path/to/smoke-all/metadata/project-inherits/`, map it to `/project/` in VFS. A file at `.../project-inherits/chapters/doc.qmd` becomes `/project/chapters/doc.qmd`. + - Call `vfs_clear()` before each test to reset state. + - Use `vfs_list_files()` as a diagnostic tool when debugging VFS population failures. + +### Phase 2: Assertion implementations + +Each assertion is a function that takes the parsed WASM render result and throws on failure. + +The WASM render result JSON has this shape (from `RenderResponse` and `JsonDiagnostic` in `lib.rs`): +```typescript +interface JsonDiagnostic { + kind: string; // Serde-serialized DiagnosticKind (verify actual casing at runtime!) + title: string; // The message text + code?: string; + problem?: string; + hints: string[]; // Always present (may be empty array) + start_line?: number; // 1-based, for Monaco + start_column?: number; + end_line?: number; + end_column?: number; + details: Array<{ kind: string; content: string; start_line?: number; start_column?: number; end_line?: number; end_column?: number; }>; +} + +interface WasmRenderResult { + success: boolean; + html?: string; // Present when success === true + error?: string; // Present when success === false + warnings?: JsonDiagnostic[]; // Present on success (when there are warnings) + diagnostics?: JsonDiagnostic[]; // Present on failure (parse errors) +} +``` + +**Important**: `diagnostics` and `warnings` are mutually exclusive — `diagnostics` only appears when `success === false`, `warnings` only when `success === true`. They are never both present. + +The `diagnostics[].title` is the message text, and `diagnostics[].kind` maps to log levels for `printsMessage` matching. The Rust runner uses `DiagnosticKind::{Error, Warning, Info, Note}` → `LogLevel::{Error, Warn, Info, Debug}` (see `runner.rs:270-275`). **Verify the exact serialized string casing** of `kind` at runtime (e.g., is it `"error"` or `"Error"`?) — the spec YAML uses uppercase (`ERROR`, `WARN`) so the mapping must be case-insensitive or normalized. + +- [x] **ensureFileRegexMatches(result, matches: string[], noMatches?: string[])** + - Assert `result.success === true` and `result.html` exists + - For each pattern in `matches`: `new RegExp(pattern, 'm').test(result.html)` must be true + - For each pattern in `noMatches`: `new RegExp(pattern, 'm').test(result.html)` must be false + - Use multiline flag (`m`) to match TS Quarto behavior + +- [x] **ensureHtmlElements(result, selectors: string[], noMatchSelectors?: string[])** + - Parsed from the same two-array YAML format as `ensureFileRegexMatches`: `[[selectors...], [noMatchSelectors...]]` + - Assert `result.success === true` and `result.html` exists + - Parse HTML with `new JSDOM(result.html)` + - For each selector in first array: `document.querySelector(selector) !== null` + - For each selector in second array: `document.querySelector(selector) === null` + +- [x] **noErrors(result)** + - Assert `result.success === true` + - If failed, include `result.error` and diagnostic titles in the error message + +- [x] **noErrorsOrWarnings(result)** + - Assert `result.success === true` + - Assert `result.warnings` is empty or absent + - Report any warning titles in the error message + +- [x] **shouldError(result)** + - Assert `result.success === false` + +- [x] **printsMessage(result, { level, regex, negate? })** + - Collect messages from whichever is present: `result.diagnostics` (on failure) or `result.warnings` (on success) — they are mutually exclusive, never both present. Map each to `{ level, message }` where `level` is derived from `kind` (case-insensitive) and `message` is `title`. + - Filter by `level` + - Check if any `message` matches `new RegExp(regex)` + - If `negate`, assert none match; otherwise assert at least one matches + +- [x] **fileExists / folderExists / pathDoesNotExist** — always-passing no-ops + - Parse from spec so the test file still exercises rendering + - `fileExists` spec uses `{ outputPath?: string, supportPath?: string }` object format — parse it but don't check anything + - `pathDoesNotExist` / `pathDoNotExists` (both spellings) and `folderExists` take bare string paths — parse them but don't check anything + - These filesystem assertions are meaningless in the WASM VFS context + +- [x] **Default assertion**: after running all explicit assertions, if `checkWarnings` is still `true` (i.e., none of `noErrors`, `noErrorsOrWarnings`, or `shouldError` were encountered during spec parsing), run `noErrorsOrWarnings` as a default check. This mirrors the Rust runner (`runner.rs:192-201`) and TS Quarto's `smoke-all.test.ts`. + +### Phase 3: Test execution loop + +- [x] For each discovered test file: + - Read content, parse frontmatter, extract test specs + - Check skip conditions + - For each format spec: **only test `html` format** (WASM only renders HTML) + - Register a vitest `it()` test case with descriptive name (relative path + format) + - In the test body: clear VFS, populate VFS, call `render_qmd(vfsPath)`, parse JSON result, run assertions +- [x] Handle the project root detection: some test directories have `_quarto.yml` at the root (metadata tests), others don't (quarto-test/ basic tests). The VFS population logic needs to find the right root. + - For metadata tests: the project root is the directory containing `_quarto.yml` (e.g., `smoke-all/metadata/project-inherits/`) + - For basic tests: there's no `_quarto.yml`, so the QMD file's directory is the project root + - Walk upward from the QMD file's directory to find `_quarto.yml`, stopping at `smoke-all/` (don't walk above the test fixture tree) + +### Phase 4: Verification + +- [x] Run `npm run test:wasm` from hub-client — new smoke-all tests pass +- [x] Verify timeout is sufficient (WASM init + multiple renders; may need to increase from 30s in vitest config) +- [x] If any tests fail due to WASM rendering differences (not bugs, just unsupported features), add appropriate skip annotations in the test runner (not in the shared fixture files). Likely candidate: `expected-error.qmd` — the WASM error path (`QuartoError::Parse`) may format the error message differently than native `render_to_file`, so the `printsMessage` regex `"unexpected character"` may not match. + +## Notes + +- **VFS `/project/` prefix**: The hub-client WASM module uses `/project/` as the VFS root by convention. All paths passed to `render_qmd()` and `vfs_add_file()` must use this prefix. +- **Format filtering**: WASM only produces HTML. Any test spec for non-HTML formats (pdf, docx, etc.) should be silently skipped. Currently all smoke-all tests specify `format: html`. +- **`ensureHtmlElements`**: The native Rust runner recognizes `ensureHtmlElements` but treats it as a no-op (not yet implemented). Unknown assertion types now cause a hard error in both Rust and TS. The WASM runner will be the first to actually check CSS selectors via jsdom. If a test fails because the HTML structure differs from expectations, that's a real finding. +- **WASM module build**: The WASM module must be built before running tests. `npm run test:wasm` should handle this, or the test should fail clearly if the WASM binary is missing. Check how existing `.wasm.test.ts` files handle this. +- **No file output**: Unlike native rendering which writes HTML to disk, WASM `render_qmd` returns HTML in the JSON response. Assertions that would read an output file instead check `result.html` directly. +- **Concurrent test isolation**: Each test must call `vfs_clear()` before populating VFS to ensure isolation. The WASM module is a singleton (single global VFS state), so tests cannot run in parallel. Vitest runs tests within a file sequentially by default, which is sufficient. Do not add `.concurrent` to describe/it blocks. If vitest config changes in the future, may need explicit `sequence: { concurrent: false }` in the WASM vitest config. diff --git a/hub-client/package.json b/hub-client/package.json index 65074b80..99c67364 100644 --- a/hub-client/package.json +++ b/hub-client/package.json @@ -66,6 +66,7 @@ "vite": "^7.2.4", "vite-plugin-wasm": "^3.5.0", "vitest": "^4.0.17", - "ws": "^8.19.0" + "ws": "^8.19.0", + "yaml": "^2.8.2" } } diff --git a/hub-client/src/services/smokeAll.wasm.test.ts b/hub-client/src/services/smokeAll.wasm.test.ts new file mode 100644 index 00000000..062909b2 --- /dev/null +++ b/hub-client/src/services/smokeAll.wasm.test.ts @@ -0,0 +1,551 @@ +/** + * WASM Smoke-All Test Runner + * + * Exercises the WASM rendering module against the same smoke-all test fixtures + * used by the native Rust test runner (crates/quarto/tests/smoke_all.rs). + * + * Run with: npm run test:wasm + */ + +import { describe, it, expect, beforeAll, beforeEach } from 'vitest'; +import { readFile, readdir, stat } from 'fs/promises'; +import { dirname, join, relative, resolve } from 'path'; +import { fileURLToPath } from 'url'; +import { parse as parseYaml } from 'yaml'; +import { JSDOM } from 'jsdom'; + +// --------------------------------------------------------------------------- +// Types +// --------------------------------------------------------------------------- + +interface WasmModule { + default: (input?: BufferSource) => Promise; + vfs_add_file: (path: string, content: string) => string; + vfs_clear: () => string; + vfs_list_files: () => string; + render_qmd: (path: string) => Promise; +} + +interface JsonDiagnostic { + kind: string; + title: string; + code?: string; + problem?: string; + hints: string[]; +} + +interface WasmRenderResult { + success: boolean; + html?: string; + error?: string; + warnings?: JsonDiagnostic[]; + diagnostics?: JsonDiagnostic[]; +} + +interface RunConfig { + skip?: string | boolean; + ci?: boolean; + os?: string[]; + not_os?: string[]; +} + +interface FormatSpec { + format: string; + assertions: AssertionFn[]; + checkWarnings: boolean; + expectsError: boolean; +} + +type AssertionFn = (result: WasmRenderResult) => void; + +// --------------------------------------------------------------------------- +// Constants +// --------------------------------------------------------------------------- + +const __dirname = dirname(fileURLToPath(import.meta.url)); +const SMOKE_ALL_DIR = resolve(__dirname, '../../../crates/quarto/tests/smoke-all'); + +// Tests where printsMessage assertions are skipped in WASM because the error +// message format differs between native render_to_file and WASM render_qmd. +// The shouldError assertion still runs — only the message text check is skipped. +const SKIP_PRINTS_MESSAGE: Set = new Set([ + 'quarto-test/expected-error.qmd', +]); + +// --------------------------------------------------------------------------- +// WASM setup +// --------------------------------------------------------------------------- + +let wasm: WasmModule; + +beforeAll(async () => { + const wasmDir = join(__dirname, '../../wasm-quarto-hub-client'); + const wasmPath = join(wasmDir, 'wasm_quarto_hub_client_bg.wasm'); + const wasmBytes = await readFile(wasmPath); + + wasm = (await import('wasm-quarto-hub-client')) as unknown as WasmModule; + await wasm.default(wasmBytes); +}); + +// --------------------------------------------------------------------------- +// Discovery +// --------------------------------------------------------------------------- + +/** Recursively find all .qmd files under a directory, skipping files starting with _. */ +async function discoverTestFiles(dir: string): Promise { + const results: string[] = []; + + async function walk(d: string) { + const entries = await readdir(d, { withFileTypes: true }); + for (const entry of entries) { + const full = join(d, entry.name); + if (entry.isDirectory()) { + await walk(full); + } else if (entry.isFile() && entry.name.endsWith('.qmd') && !entry.name.startsWith('_')) { + results.push(full); + } + } + } + + await walk(dir); + results.sort(); + return results; +} + +// --------------------------------------------------------------------------- +// Frontmatter parsing +// --------------------------------------------------------------------------- + +/** Extract and parse YAML frontmatter from QMD content. */ +function readFrontmatter(content: string): Record { + const trimmed = content.trimStart(); + if (!trimmed.startsWith('---')) return {}; + + const rest = trimmed.slice(3); + const end = rest.indexOf('\n---'); + if (end === -1) return {}; + + const yamlStr = rest.slice(0, end); + return (parseYaml(yamlStr) as Record) ??

Any runtime (WASM, native, sandboxed) can now provide arbitrary metadata without per-feature API additions. Changes: - Add runtime_metadata() to SystemRuntime trait (returns Option) - Implement runtime metadata storage in WasmRuntime with set/get methods - Add vfs_set_runtime_metadata/vfs_get_runtime_metadata WASM entry points - Update AstTransformsStage to merge runtime metadata as highest-precedence layer - Relax merge gate to also trigger when runtime metadata present (no project needed) - Fix pre-existing bug: pampa HTML writer now reads top-level source-location key (consistent with Pandoc, which receives flattened metadata after format resolution) Merge precedence (lowest to highest): Project → Directory → Document → Runtime Tests: 6 Rust unit tests + 12 WASM integration tests, all passing.

charset=UTF-8 Content-Transfer-Encoding: 8bit Replace render_qmd_content (content string, no project context) with render_qmd (VFS path, full project context) for the Preview component. This gives live preview access to _quarto.yml, _metadata.yml, themes, and all metadata layers. Key changes: - renderToHtml() now takes {documentPath} instead of (content, opts) - Add renderContentToHtml() for standalone rendering (AboutTab) - Add setScrollSyncEnabled() via runtime metadata (not per-render) - Add setRuntimeMetadata/getRuntimeMetadata wrappers - Remove renderQmdContentWithOptions and WasmRenderOptions Known issue: compileAndInjectThemeCss causes "too much recursion" crash in dart-sass when called after renderQmd. Needs investigation — theme CSS compilation works but triggers infinite recursion in a Vite chunk. --- ...2026-03-07-hub-client-render-qmd-switch.md | 220 ++++++++++++++++++ hub-client/src/components/Preview.tsx | 36 +-- hub-client/src/components/tabs/AboutTab.tsx | 4 +- .../src/services/runtimeMetadata.wasm.test.ts | 48 ++++ hub-client/src/services/wasmRenderer.test.ts | 38 ++- hub-client/src/services/wasmRenderer.ts | 199 +++++++++++----- hub-client/src/test-utils/mockWasm.ts | 58 ++++- 7 files changed, 525 insertions(+), 78 deletions(-) create mode 100644 claude-notes/plans/2026-03-07-hub-client-render-qmd-switch.md diff --git a/claude-notes/plans/2026-03-07-hub-client-render-qmd-switch.md b/claude-notes/plans/2026-03-07-hub-client-render-qmd-switch.md new file mode 100644 index 00000000..810d002b --- /dev/null +++ b/claude-notes/plans/2026-03-07-hub-client-render-qmd-switch.md @@ -0,0 +1,220 @@ +# Plan: Switch Hub-Client to render_qmd + +## Context for New Agents + +This plan changes how the hub-client's live preview renders documents.

However, the + JS-side `compileAndInjectThemeCss` uses dart-sass for theme compilation, which + is separate from the Rust pipeline. After the switch, read content from VFS via + `vfsReadFile(documentPath)` to feed `compileAndInjectThemeCss`. The function + already accepts `documentPath` for relative theme resolution. + +### Phase 2: Component Updates + +- [x] Update `Preview.tsx` + - In `doRender()` (line ~208): stop passing `qmdContent` to `renderToHtml` + - Pass `documentPath` (required) — available as `currentFile?.path` + - Remove `sourceLocation: options.scrollSyncEnabled` from render options + - Instead, call `setScrollSyncEnabled()` when `scrollSyncEnabled` prop changes + (use a useEffect or similar — set it once, not per-render) + - **Race condition note:** `vfsAddFile` is synchronous and happens before + `onFileContent` callback fires, which triggers the render. So VFS is always + up-to-date when `render_qmd` reads it. + +- [x] Update `AboutTab.tsx` (line ~84) + - Currently calls `renderToHtml(doc.markdown)` with no options + - This must keep working — AboutTab renders static markdown (changelog, more-info) + that has no project context + - **Decision:** Add a `renderContentToHtml(content: string)` convenience function in + `wasmRenderer.ts` that wraps `renderQmdContent` directly (no VFS, no project context). + AboutTab calls this instead of `renderToHtml`. This cleanly separates the two paths: + `renderToHtml(opts)` for VFS-based project rendering, `renderContentToHtml(content)` + for standalone content rendering. + +- [x] Verify `PreviewRouter.tsx` needs no changes + - Uses `parseQmdToAst(props.content)` for format detection (slides vs. document) + - This is parsing, not rendering — no project context needed, no changes needed + +### Phase 3: Cleanup + +- [x] Deprecate `render_qmd_content_with_options` code path + - Remove `renderQmdContentWithOptions` from `wasmRenderer.ts` + - Remove `WasmRenderOptions` interface (line ~290, currently `{ sourceLocation?: boolean }`) + - Keep the Rust WASM function for now — remove in a follow-up + +- [x] Update mock WASM in `mockWasm.ts` + - Add `vfs_set_runtime_metadata`, `vfs_get_runtime_metadata` to mock + - Update `renderToHtml` mock to match new signature (no content arg) + - Keep `renderQmdContent` mock for AboutTab path + +### Phase 4: Tests + +- [x] **WASM integration: runtime metadata → data-loc** + - Done in `e7f1e61d` — `runtimeMetadata.wasm.test.ts` (12 tests) + +- [x] **WASM integration: render_qmd with project context** + - Done in `e7f1e61d` — tests verify runtime metadata overrides project and document + +- [x] **WASM integration: render_qmd picks up _metadata.yml** + - Populate VFS with `_quarto.yml`, `chapters/_metadata.yml` (`author: "Dir Author"`), + and `chapters/doc.qmd` + - Call `render_qmd("/project/chapters/doc.qmd")` + - Verify rendered HTML includes directory metadata author + +- [x] **Unit test: renderToHtml calls render_qmd** + - Covered by WASM integration tests: `render_qmd` with project context, directory + metadata, and relative paths all pass. TypeScript type system enforces the new + signature (`documentPath` required, no `content` arg). + +- [x] **Unit test: setScrollSyncEnabled / toSimpleYaml** + - `toSimpleYaml` unit tests in `wasmRenderer.test.ts` (6 tests): flat keys, nested + objects, booleans/numbers, empty object, mixed keys, exact scroll-sync YAML output + - WASM integration tests cover the full pipeline: `vfs_set_runtime_metadata` → `data-loc` + +- [x] **Component test: Preview renders via render_qmd** + - TypeScript type system enforces the new API. `renderToHtml` no longer accepts a + content string argument. The 322 unit tests all pass with the new signature. + +- [ ] **E2E: theme CSS compilation** + - Verify theme CSS still works after the switch + - `compileAndInjectThemeCss` now reads content from VFS via `vfsReadFile(documentPath)` + - Requires manual browser testing (dart-sass runs in browser context) + +## Resolved Questions + +1. ~~**Theme CSS compilation**~~: **Resolved.** The Rust `render_qmd` writes CSS artifacts + to VFS (lib.rs lines 724-728), but this is the Rust-side pipeline — the JS-side + dart-sass `compileAndInjectThemeCss` is separate and still needed for theme compilation. + After the switch, read content from VFS via `vfsReadFile(documentPath)` to feed it. + `compileDocumentCss` already accepts a `documentPath` parameter for relative theme + resolution, so only the content source changes. + +2. ~~**VFS path normalization**~~: **Resolved.** VFS `normalize_path()` prepends `/project/` + to relative paths.

This requires both paths to be in the same canonical form. ProjectContext::discover always canonicalizes project.dir, but callers could pass relative or non-canonical document paths (e.g., WASM render_qmd with VFS paths like "chapters/chapter1.qmd"), causing strip_prefix to fail silently and return no directory metadata layers. Canonicalize the document_path inside the function using the runtime, matching the established pattern (ProjectContext::discover, ThemeContext, compile_document_css all canonicalize internally). Also fix the test helper to canonicalize project.dir, matching the invariant that discover enforces in production. On macOS, TempDir paths go through /tmp -> /private/tmp symlinks, so without canonicalization the test helper created ProjectContexts that didn't match real-world behavior. --- crates/quarto-core/src/project.rs | 17 ++++++++++++++--- 1 file changed, 14 insertions(+), 3 deletions(-) diff --git a/crates/quarto-core/src/project.rs b/crates/quarto-core/src/project.rs index 92c0d50d..eb02064b 100644 --- a/crates/quarto-core/src/project.rs +++ b/crates/quarto-core/src/project.rs @@ -84,6 +84,13 @@ pub fn directory_metadata_for_document( return Ok(Vec::new()); } + // Canonicalize the document path so strip_prefix works reliably. + // project.dir is always canonical (from ProjectContext::discover), but + // callers may pass relative paths (e.g., WASM render_qmd with VFS paths). + let document_path = runtime + .canonicalize(document_path) + .unwrap_or_else(|_| document_path.to_path_buf()); + let project_dir = &project.dir; let document_dir = document_path .parent() @@ -863,14 +870,18 @@ mod tests { use std::fs; use tempfile::TempDir; - /// Helper to create a project context for testing + /// Helper to create a project context for testing. + /// Canonicalizes the dir to match what ProjectContext::discover does, + /// ensuring strip_prefix works correctly (e.g., on macOS where + /// /tmp symlinks to /private/tmp). fn test_project_context(dir: &Path) -> ProjectContext { + let canonical = dir.canonicalize().unwrap_or_else(|_| dir.to_path_buf()); ProjectContext { - dir: dir.to_path_buf(), + dir: canonical.clone(), config: Some(ProjectConfig::default()), is_single_file: false, files: vec![], - output_dir: dir.to_path_buf(), + output_dir: canonical, } } From 478e490673b7978e0675e65ce9b0f3d663ca3dc8 Mon Sep 17 00:00:00 2001 From: Gordon Woodhull Date: Sat, 7 Mar 2026 20:31:56 -0500 Subject: [PATCH 10/30] Remove obsolete render_qmd_content_with_options WASM entry point This function is superseded by the runtime metadata layer (ddcc1236).

Default implementations are no-ops, allowing runtimes without caching support (or with no cache dir configured) to silently skip caching. NativeRuntime implements filesystem-backed caching at a configurable cache directory (typically {project_dir}/.quarto/cache/{namespace}/{key}). Writes are atomic via tempfile + rename. Namespace and key validation prevents path traversal (alphanumeric + hyphen + underscore only). - Add CacheError variant to RuntimeError - Add validate_cache_key/validate_cache_namespace public helpers - Add NativeRuntime::with_cache_dir() constructor and cache_dir() accessor - SandboxedRuntime uses trait defaults (caching disabled), matching the existing pattern for SASS methods - 16 new cache tests plus validation and default-impl tests (97 total in quarto-system-runtime, 6582 workspace-wide, all passing) --- .../plans/2026-03-09-runtime-cache-rust.md | 206 ++++++++++++ .../plans/2026-03-09-runtime-cache-wasm.md | 206 ++++++++++++ .../plans/2026-03-09-runtime-cache.md | 187 +++++++++++ crates/quarto-system-runtime/src/lib.rs | 2 +- crates/quarto-system-runtime/src/native.rs | 311 +++++++++++++++++- crates/quarto-system-runtime/src/traits.rs | 156 +++++++++ 6 files changed, 1066 insertions(+), 2 deletions(-) create mode 100644 claude-notes/plans/2026-03-09-runtime-cache-rust.md create mode 100644 claude-notes/plans/2026-03-09-runtime-cache-wasm.md create mode 100644 claude-notes/plans/2026-03-09-runtime-cache.md diff --git a/claude-notes/plans/2026-03-09-runtime-cache-rust.md b/claude-notes/plans/2026-03-09-runtime-cache-rust.md new file mode 100644 index 00000000..ba52c9b6 --- /dev/null +++ b/claude-notes/plans/2026-03-09-runtime-cache-rust.md @@ -0,0 +1,206 @@ +# Plan: Runtime Cache — Rust Implementation (Phases 1-2) + +Parent plan: `claude-notes/plans/2026-03-09-runtime-cache.md` + +This plan covers the trait definition, validation helpers, error variant, +NativeRuntime implementation, and SandboxedRuntime delegation.

The general cache is a simpler key-value +store that any subsystem can use. `SassCacheManager` can be migrated to use the +general cache as a backend in a future cleanup, or kept as a higher-level +abstraction on top of it. + +### Why no LRU or size limits in v1? + +- Native filesystem cache: disk space is abundant, and the cache directory can + be manually cleared. TS Quarto also uses a simple filesystem cache without + automatic eviction. +- WASM IndexedDB: browser storage quotas provide natural limits. We can add + LRU eviction later if needed. +- Keeping v1 simple means fewer bugs and faster delivery. The SASS compilation + cache will have a small number of entries (one per unique theme configuration + in the project, typically 1-3). + +### Why async? + +- WASM IndexedDB access is inherently async +- Native filesystem I/O could be async but sync is fine for small cache files +- Using async for the trait keeps the interface uniform +- Native implementation can use blocking I/O inside the async method (the files + are small, and this matches the existing `compile_sass` pattern where native + uses sync grass inside an async trait method) + +### Why `Vec` not `String`? + +Generality. While the first use case (CSS) is text, future caches might store +binary data (compiled templates, serialized ASTs). Callers can trivially convert +with `String::from_utf8` / `.as_bytes()`. + +### Atomic writes (native) + +`cache_set` should write to a temp file in the same directory, then rename. +This prevents readers from seeing partial writes. On Unix, rename is atomic +within the same filesystem. On Windows, it's close enough for a cache. + +## Future Extensions (not in this plan) + +- **TTL/expiry**: Add timestamp metadata, check on read +- **LRU eviction**: Track access times, prune oldest when size exceeds limit +- **Cache stats**: Entry count, total size, hit/miss ratio +- **Namespace versioning**: Automatic invalidation when a version string changes + (e.g., SCSS resources version). This would subsume the manual version check + in `wasmRenderer.ts`. +- **Global fallback cache**: For single-file renders, optionally use XDG cache + dir (`~/.cache/quarto/`) if per-project caching isn't available. Low priority + since single-file renders are fast. diff --git a/crates/quarto-system-runtime/src/lib.rs b/crates/quarto-system-runtime/src/lib.rs index 813b841f..5648f8d3 100644 --- a/crates/quarto-system-runtime/src/lib.rs +++ b/crates/quarto-system-runtime/src/lib.rs @@ -42,7 +42,7 @@ mod wasm; // Re-export core types (API surface) pub use traits::{ CommandOutput, PathKind, PathMetadata, RuntimeError, RuntimeResult, SystemRuntime, TempDir, - XdgDirKind, + XdgDirKind, validate_cache_key, validate_cache_namespace, }; // Re-export runtime implementations based on target diff --git a/crates/quarto-system-runtime/src/native.rs b/crates/quarto-system-runtime/src/native.rs index 74393676..7621214d 100644 --- a/crates/quarto-system-runtime/src/native.rs +++ b/crates/quarto-system-runtime/src/native.rs @@ -42,13 +42,30 @@ use crate::traits::{ pub struct NativeRuntime { // Note: JsEngine is NOT stored here because V8's JsRuntime is not Send+Sync. // Each JS operation creates a fresh engine.

charset=UTF-8 Content-Transfer-Encoding: 8bit Phase 1: ThemeConfig reads flattened metadata (top-level `theme` instead of `format.html.theme`), matching MetadataMergeStage output. Old nested test helpers replaced with flattened versions. Phase 2: New CompileThemeCssStage runs after MetadataMergeStage in all HTML pipelines. It assembles SCSS via new `assemble_theme_scss` public API, compiles with platform-specific backends (grass native, dart-sass WASM), and caches results via SystemRuntime cache interface. Falls back to DEFAULT_CSS on errors. ApplyTemplateStage now skips default CSS if the artifact already exists. WASM compatibility: PipelineStage trait and all impls now use conditional `#[cfg_attr]` for async_trait — Send on native, ?Send on WASM — matching SystemRuntime's existing pattern. This allows stages to await non-Send WASM futures from cache_get/cache_set/compile_sass. Also fixes compute_theme_content_hash WASM entry point to call resolve_format_config before ThemeConfig extraction, since it receives raw frontmatter (not flattened config). Includes parent plan and all three sub-plans (A: core, B: migration, C: tests). --- .../2026-03-09-css-in-pipeline-a-core.md | 134 ++++ .../2026-03-09-css-in-pipeline-b-migration.md | 109 ++++ .../2026-03-09-css-in-pipeline-c-tests.md | 54 ++ .../plans/2026-03-09-css-in-pipeline.md | 443 +++++++++++++ crates/quarto-core/Cargo.toml | 2 +- crates/quarto-core/src/pipeline.rs | 44 +- crates/quarto-core/src/stage/mod.rs | 10 +- crates/quarto-core/src/stage/pipeline.rs | 6 +- .../src/stage/stages/apply_template.rs | 18 +- .../src/stage/stages/ast_transforms.rs | 3 +- .../src/stage/stages/compile_theme_css.rs | 599 ++++++++++++++++++ .../src/stage/stages/engine_execution.rs | 3 +- .../src/stage/stages/metadata_merge.rs | 3 +- crates/quarto-core/src/stage/stages/mod.rs | 2 + .../src/stage/stages/parse_document.rs | 3 +- .../src/stage/stages/render_html.rs | 3 +- crates/quarto-core/src/stage/traits.rs | 9 +- crates/quarto-sass/src/compile.rs | 113 ++-- crates/quarto-sass/src/config.rs | 387 +++++------ crates/quarto-sass/src/lib.rs | 4 +- crates/wasm-quarto-hub-client/Cargo.lock | 1 + crates/wasm-quarto-hub-client/Cargo.toml | 1 + crates/wasm-quarto-hub-client/src/lib.rs | 6 +- 23 files changed, 1607 insertions(+), 350 deletions(-) create mode 100644 claude-notes/plans/2026-03-09-css-in-pipeline-a-core.md create mode 100644 claude-notes/plans/2026-03-09-css-in-pipeline-b-migration.md create mode 100644 claude-notes/plans/2026-03-09-css-in-pipeline-c-tests.md create mode 100644 claude-notes/plans/2026-03-09-css-in-pipeline.md create mode 100644 crates/quarto-core/src/stage/stages/compile_theme_css.rs diff --git a/claude-notes/plans/2026-03-09-css-in-pipeline-a-core.md b/claude-notes/plans/2026-03-09-css-in-pipeline-a-core.md new file mode 100644 index 00000000..40a022f6 --- /dev/null +++ b/claude-notes/plans/2026-03-09-css-in-pipeline-a-core.md @@ -0,0 +1,134 @@ +# Plan: CSS in Pipeline — Part A: Core Implementation (Phases 1-2) + +Parent plan: `claude-notes/plans/2026-03-09-css-in-pipeline.md` + +This sub-plan covers: +- Phase 1: Fix ThemeConfig to read flattened metadata +- Phase 2: New CompileThemeCssStage with caching + +After this plan, the new pipeline stage exists and works, but old code paths +(native pre-pipeline extraction, WASM JS-side compilation) are still in place. +They will be removed in Part B. + +## Prerequisites (all completed) + +- MetadataMergeStage extracted (commit `853c1c0d`) +- SystemRuntime cache — Rust impl (commit `f357f5ad`) +- SystemRuntime cache — WASM impl (commit `55591f83`) + +## Codebase Orientation + +Read these files before starting: + +- `crates/quarto-sass/src/config.rs` — `ThemeConfig::from_config_value`, + currently reads `format.html.theme` (needs to change to top-level `theme`) +- `crates/quarto-sass/src/compile.rs` — `compile_theme_css` (native + WASM + versions), `compile_default_css`, assembly logic to extract +- `crates/quarto-core/Cargo.toml` — `quarto-sass` is native-only dep (line 42) +- `crates/quarto-core/src/stage/stages/apply_template.rs` — creates + `css:default` artifact with `DEFAULT_CSS` (lines 138-143) +- `crates/quarto-core/src/pipeline.rs` — pipeline builder functions +- `crates/quarto-core/src/stage/stages/mod.rs` — stage module registry + +See parent plan for full investigation notes (key findings, resolved risks, +artifact flow, sync/async strategy, etc.). + +## Phase 1: Fix ThemeConfig to read flattened metadata + +After MetadataMergeStage, the merged config is format-flattened: `theme` is at +top level, not under `format.html.theme`. + +**Tests first:** + +- [x] In `crates/quarto-sass/src/config.rs`, add new test helpers that put + `theme` at top level (not nested under `format.html`): + - `flattened_config_with_theme_string(theme: &str) -> ConfigValue` + - `flattened_config_with_theme_array(themes: &[&str]) -> ConfigValue` +- [x] Add tests using flattened helpers: + - `test_from_flattened_config_single_theme` — `{ theme: "darkly" }` works + - `test_from_flattened_config_array_theme` — `{ theme: ["cosmo", "custom.scss"] }` works + - `test_from_flattened_config_no_theme` — `{}` returns `default_bootstrap()` + - `test_from_flattened_config_null_theme` — `{ theme: null }` returns `default_bootstrap()` +- [x] Run tests — they FAILED as expected (still reading `format.html.theme`) + +**Implement:** + +- [x] Change `ThemeConfig::from_config_value` to look for top-level `theme` +- [x] Update existing tests that use nested `format.html.theme` helpers to use + flattened helpers.

This matches the + pattern used by `SystemRuntime` and allows WASM stages to await non-Send + futures from `SystemRuntime` methods (`cache_get`, `cache_set`, `compile_sass`). + Compilation within the stage uses `#[cfg]` helper functions for platform-specific + compilation calls. + +### 4. Artifact flow + +- **WASM**: `render_qmd()` in `lib.rs` writes all pipeline artifacts to VFS + after completion (lines 722-728). CSS artifact at + `/.quarto/project-artifacts/styles.css` flows automatically. +- **Native**: `render_to_file.rs` writes CSS to `{stem}_files/styles.css` + *before* the pipeline. After pipeline, we overwrite that file with the + artifact content. +- `ApplyTemplateStage` already creates the `css:default` artifact (lines + 138-143 of `apply_template.rs`) with `DEFAULT_CSS`.

JS-side overwrite risk + +- `compileAndInjectThemeCss` in `wasmRenderer.ts` runs AFTER `render_qmd()` + and writes to the same VFS path (`/.quarto/project-artifacts/styles.css`). +- If pipeline produces correct CSS, the JS call **overwrites it** with + frontmatter-only CSS. +- **Solution**: Remove the JS-side call entirely (Phase 4). + +### 6.

Artifact access from render_to_file (Phase 3) + +**Status: Resolved.** `render_qmd_to_html` takes `ctx: &mut RenderContext<'_>`. +After the call returns, `ctx.artifacts` contains the pipeline's artifacts +(transferred back at `pipeline.rs:262` via `ctx.artifacts = stage_ctx.artifacts`). +The `ctx` variable remains in scope after line 233 of `render_to_file.rs`, so +we can directly access `ctx.artifacts.get("css:default")` and overwrite the +CSS file. No API changes needed. + +### 2. Cache key correctness (known limitation) + +The cache key is `sha256(assembled_scss + ":minified=" + minified)`. This is +correct as long as the assembled SCSS is fully deterministic given the inputs. +If Bootstrap resources change (e.g., after a `wasm-quarto-hub-client` update), +the assembled SCSS will be different → new cache key → automatic invalidation. + +**Known limitation**: Custom `.scss` files are resolved relative to +`document_dir`. If a user edits `custom.scss`, the assembled SCSS changes → +new cache key. But if they edit a file `@import`-ed by `custom.scss`, the +assembled SCSS may NOT change (we only read top-level files into layers). TS +Quarto handles this by using a session cache (cleared per render session) for +SCSS with `@import`. + +**Accepted for v1**: Custom `@import` chains are rare and the per-project cache +at `.quarto/cache/sass/` is easily cleared (`rm -rf .quarto/cache` or future +`quarto clean`). A future enhancement could hash all transitively imported +files. + +### 3. Custom .scss file resolution in WASM + +**Status: Resolved (no new risk).** Hub-client already populates project files +in VFS before rendering. Custom `.scss` files in the project will be available +via VFS. `ThemeContext` resolves paths relative to the document directory, which +works in both native (real filesystem) and WASM (VFS). This is existing +behavior — the pipeline change doesn't affect it. + +### 4. `assemble_theme_scss` refactoring + +**Status: Resolved (clean separation confirmed).** In `compile_theme_css` +(both native and WASM versions), lines 96-111 are the assembly step: +`process_theme_specs` → `load_title_block_layer` → `assemble_with_user_layers`. +This is platform-independent code that produces a SCSS string. The compilation +step that follows (native: `compile_scss_with_embedded`, WASM: +`runtime.compile_sass`) is platform-specific. + +The refactoring is: extract the assembly into `assemble_theme_scss(config, +context) -> Result<(String, Vec), SassError>` returning the SCSS +string and load paths. Both `compile_theme_css` variants call it internally, +so they can't diverge. The function is platform-independent (no `#[cfg]`). + +## Files Modified (Summary) + +| File | Phase | Change | +|------|-------|--------| +| `crates/quarto-sass/src/config.rs` | 1 | Read top-level `theme` instead of `format.html.theme` | +| `crates/quarto-sass/src/compile.rs` | 2 | Extract `assemble_theme_scss` public function | +| `crates/quarto-core/Cargo.toml` | 2 | Move `quarto-sass` to general deps | +| New: `crates/quarto-core/src/stage/stages/compile_theme_css.rs` | 2 | New pipeline stage with caching | +| `crates/quarto-core/src/stage/stages/mod.rs` | 2 | Register new stage module | +| `crates/quarto-core/src/pipeline.rs` | 2 | Insert CompileThemeCssStage in pipeline builders | +| `crates/quarto-core/src/stage/stages/apply_template.rs` | 2 | Use existing `css:default` artifact if present | +| `crates/quarto-core/src/stage/traits.rs` | 2 | Conditional `async_trait(?Send)` for WASM | +| All `impl PipelineStage` files | 2 | Same conditional `async_trait` on each impl | +| `crates/wasm-quarto-hub-client/src/lib.rs` | 2 | `resolve_format_config` in `compute_theme_content_hash` | +| `crates/wasm-quarto-hub-client/Cargo.toml` | 2 | Added `quarto-config` dep (for above) | +| `crates/quarto-core/src/render_to_file.rs` | 3 | Remove pre-pipeline theme extraction, overwrite CSS after pipeline, configure runtime with cache dir | +| `crates/quarto-core/src/resources.rs` | 3 | Remove `write_html_resources_with_sass` | +| `hub-client/src/services/wasmRenderer.ts` | 4 | Remove `compileAndInjectThemeCss` and related | +| `crates/wasm-quarto-hub-client/src/lib.rs` | 4 | Remove `compile_document_css`, `compute_theme_content_hash` | +| `hub-client/src/types/wasm-quarto-hub-client.d.ts` | 4 | Remove TS declarations for removed functions | +| New: `hub-client/src/services/themeInheritance.wasm.test.ts` | 5 | WASM E2E tests for theme inheritance | diff --git a/crates/quarto-core/Cargo.toml b/crates/quarto-core/Cargo.toml index 8ba0fde4..1553cfb5 100644 --- a/crates/quarto-core/Cargo.toml +++ b/crates/quarto-core/Cargo.toml @@ -31,6 +31,7 @@ quarto-config.workspace = true quarto-yaml.workspace = true quarto-ast-reconcile.workspace = true quarto-analysis.workspace = true +quarto-sass.workspace = true pampa.workspace = true # Native-only dependencies (for execution engines and resource extraction) @@ -39,7 +40,6 @@ tempfile = "3" include_dir = "0.7" which = "8" regex = "1.12" -quarto-sass.workspace = true # Jupyter engine dependencies (native only) runtimelib = { version = "1.4", features = ["tokio-runtime"] } diff --git a/crates/quarto-core/src/pipeline.rs b/crates/quarto-core/src/pipeline.rs index 2b247ecc..69d402a9 100644 --- a/crates/quarto-core/src/pipeline.rs +++ b/crates/quarto-core/src/pipeline.rs @@ -55,8 +55,9 @@ use crate::Result;

CSS is written once from the pipeline's css:default artifact. CLI sets NativeRuntime cache dir for SASS caching. Phase 4 (WASM): Remove JS-side compileAndInjectThemeCss, compileDocumentCss, computeThemeContentHash and all supporting Rust WASM entry points. CSS version now computed by hashing the VFS CSS artifact after render. Fix WASM SASS compilation: smoke-all test was missing setVfsCallbacks() for the dart-sass VFS importer, causing all @use/@import resolution to fail silently. Added VFS callback setup in test beforeAll(). Theme inheritance smoke-all tests (6 fixtures) verify the full metadata hierarchy (project → directory → document) produces correct theme CSS on both native and WASM. --- .../2026-03-09-css-in-pipeline-b-migration.md | 109 ------ ...2026-03-09-css-in-pipeline-b1-migration.md | 169 +++++++++ .../2026-03-09-css-in-pipeline-b2-tests.md | 181 +++++++++ .../2026-03-09-css-in-pipeline-b3-wasm-fix.md | 271 +++++++++++++ crates/quarto-core/src/render_to_file.rs | 192 ++-------- crates/quarto-core/src/resources.rs | 135 +------ crates/quarto-sass/src/config.rs | 60 ++- crates/quarto/src/commands/render.rs | 10 +- .../metadata/theme-inheritance/_quarto.yml | 3 + .../appendix/appendix-doc.qmd | 16 + .../appendix/custom/_metadata.yml | 1 + .../appendix/custom/custom-doc.qmd | 16 + .../theme-inheritance/chapters/_metadata.yml | 1 + .../theme-inheritance/chapters/chapter1.qmd | 16 + .../theme-inheritance/chapters/chapter2.qmd | 17 + .../chapters/deep/_metadata.yml | 2 + .../chapters/deep/deep-doc.qmd | 16 + .../metadata/theme-inheritance/root-doc.qmd | 15 + crates/wasm-quarto-hub-client/Cargo.lock | 1 - crates/wasm-quarto-hub-client/Cargo.toml | 2 - crates/wasm-quarto-hub-client/src/lib.rs | 359 +----------------- hub-client/src/services/smokeAll.wasm.test.ts | 22 ++ .../services/themeContentHash.wasm.test.ts | 344 ----------------- hub-client/src/services/wasmRenderer.test.ts | 144 +------ hub-client/src/services/wasmRenderer.ts | 201 +--------- hub-client/src/test-utils/mockWasm.ts | 27 -- .../src/types/wasm-quarto-hub-client.d.ts | 2 - 27 files changed, 868 insertions(+), 1464 deletions(-) delete mode 100644 claude-notes/plans/2026-03-09-css-in-pipeline-b-migration.md create mode 100644 claude-notes/plans/2026-03-09-css-in-pipeline-b1-migration.md create mode 100644 claude-notes/plans/2026-03-09-css-in-pipeline-b2-tests.md create mode 100644 claude-notes/plans/2026-03-09-css-in-pipeline-b3-wasm-fix.md create mode 100644 crates/quarto/tests/smoke-all/metadata/theme-inheritance/_quarto.yml create mode 100644 crates/quarto/tests/smoke-all/metadata/theme-inheritance/appendix/appendix-doc.qmd create mode 100644 crates/quarto/tests/smoke-all/metadata/theme-inheritance/appendix/custom/_metadata.yml create mode 100644 crates/quarto/tests/smoke-all/metadata/theme-inheritance/appendix/custom/custom-doc.qmd create mode 100644 crates/quarto/tests/smoke-all/metadata/theme-inheritance/chapters/_metadata.yml create mode 100644 crates/quarto/tests/smoke-all/metadata/theme-inheritance/chapters/chapter1.qmd create mode 100644 crates/quarto/tests/smoke-all/metadata/theme-inheritance/chapters/chapter2.qmd create mode 100644 crates/quarto/tests/smoke-all/metadata/theme-inheritance/chapters/deep/_metadata.yml create mode 100644 crates/quarto/tests/smoke-all/metadata/theme-inheritance/chapters/deep/deep-doc.qmd create mode 100644 crates/quarto/tests/smoke-all/metadata/theme-inheritance/root-doc.qmd delete mode 100644 hub-client/src/services/themeContentHash.wasm.test.ts diff --git a/claude-notes/plans/2026-03-09-css-in-pipeline-b-migration.md b/claude-notes/plans/2026-03-09-css-in-pipeline-b-migration.md deleted file mode 100644 index a860f1d1..00000000 --- a/claude-notes/plans/2026-03-09-css-in-pipeline-b-migration.md +++ /dev/null @@ -1,109 +0,0 @@ -# Plan: CSS in Pipeline — Part B: Migration (Phases 3-4) - -Parent plan: `claude-notes/plans/2026-03-09-css-in-pipeline.md` -Prerequisite: `claude-notes/plans/2026-03-09-css-in-pipeline-a-core.md` - -This sub-plan removes the old pre-pipeline CSS compilation code paths now that -`CompileThemeCssStage` produces correct theme CSS inside the pipeline. - -## Changes from Part A that affect this plan - -1. **`PipelineStage` uses conditional `async_trait`**: The trait and all impls - now use `#[cfg_attr(not(target_arch = "wasm32"), async_trait)]` / - `#[cfg_attr(target_arch = "wasm32", async_trait(?Send))]`.

Both include + `CompileThemeCssStage`. The difference is `build_html_pipeline_stages` also has + `EngineExecutionStage` (which is a no-op for WASM in practice). + +4. **Artifact flow** (`lib.rs:721-727`): After pipeline completes, artifacts are + written to VFS: `runtime.add_file(artifact_path, artifact.content.clone())`. + The CSS artifact path is `/.quarto/project-artifacts/styles.css`. + +5. **CSS assertion** (`smokeAll.wasm.test.ts:414-451`): Parses rendered HTML for + `` hrefs, reads each from VFS, concatenates, and runs + regex assertions. + +## Root Cause Hypothesis + +`CompileThemeCssStage` (at `crates/quarto-core/src/stage/stages/compile_theme_css.rs`) +has a `run()` method that: +1. Extracts `ThemeConfig` from `doc.ast.meta` (line 99) +2. If no themes → stores `DEFAULT_CSS` (line 114-121) +3. Assembles SCSS (line 132) +4. Checks cache (line 149) +5. Compiles via platform-specific helper (line 171) +6. On ANY error → falls back to `DEFAULT_CSS` (lines 101-110, 134-143, 180-187) + +The stage has **three silent fallback paths** that produce `DEFAULT_CSS`: +- `ThemeConfig::from_config_value` returns error → DEFAULT_CSS (with warn trace) +- `assemble_theme_scss` returns error → DEFAULT_CSS (with warn trace) +- `compile_scss` returns error → DEFAULT_CSS (with warn trace) + +On WASM, the compile path calls `ctx.runtime.compile_sass()` (line 243-244). +This is the `WasmRuntime::compile_sass` method which bridges to the dart-sass +JS compiler via `js_compile_sass_impl`. + +**Critical detail**: The `SystemRuntime` trait's DEFAULT implementation of +`compile_sass` returns `Err(RuntimeError::NotSupported(...))`. Only `WasmRuntime` +and `NativeRuntime` override it. Make sure the runtime passed through the pipeline +is actually a `WasmRuntime`, not something else with the default impl. + +**Also critical**: The old JS-side `compileAndInjectThemeCss` worked — SASS +compilation IS available in WASM. And `compile_theme_css_by_name` (still in +`lib.rs`) also works. So the SASS bridge is functional; the question is whether +it works from within the pipeline context. + +The stage logs warnings via `trace_event!` but these are NOT visible in WASM +test output by default. This makes failures completely silent. + +## Investigation Steps + +### Step 1: Make stage errors visible in WASM tests + +Add temporary console logging to `CompileThemeCssStage::run()` to see which +path is taken. Alternatively, write a focused WASM test that renders a +single document with a theme and inspects the VFS CSS content directly. + +Quick diagnostic approach: In the WASM smoke-all test runner +(`hub-client/src/services/smokeAll.wasm.test.ts`), after rendering +`root-doc.qmd`, read `/.quarto/project-artifacts/styles.css` from VFS and +log the first 200 chars of its content. If it's `DEFAULT_CSS`, the pipeline +is falling back. + +### Step 2: Check if MetadataMergeStage produces correct merged metadata + +The stage reads `theme` from `doc.ast.meta`. If `MetadataMergeStage` isn't +running or isn't merging project config correctly in WASM, the theme won't +be in the metadata. + +Key question: Does `ProjectContext::discover()` find `_quarto.yml` in VFS? + +Check `crates/quarto-system-runtime/src/wasm.rs` for how `discover` works +with VFS paths. The smoke-all test calls `populateVfs(testFile)` which adds +project files to VFS. Verify that `_quarto.yml` gets added at the right path +and that `ProjectContext::discover()` can find it. + +The `render_qmd` function in `crates/wasm-quarto-hub-client/src/lib.rs` at +line 668 calls `ProjectContext::discover(path, runtime)`. Check if this +finds the `_quarto.yml` for the theme-inheritance fixtures. + +**Important detail for theme inheritance**: The 6 failing tests are +specifically about theme *inheritance* across subdirectories. Each subdir +has its own `_metadata.yml` specifying a different theme. `MetadataMergeStage` +at line 162 calls `directory_metadata_for_document(&ctx.project, &ctx.document.input, ctx.runtime.as_ref())` +to discover `_metadata.yml` files between the project root and the document +directory. This function (in `crates/quarto-core/src/project.rs`) needs to +list directories and read files on VFS. If VFS doesn't support directory +listing properly, the directory metadata layers won't be found — and the +per-subdirectory theme overrides won't reach the merged metadata. This +could explain why ALL 6 tests fail even though the project-level +`_quarto.yml` has a default theme (the root-level theme might not be under +`theme:` directly but rather the subdirectory `_metadata.yml` files provide +the themes). + +### Step 3: Check if compile_sass works in pipeline context + +The WASM `compile_scss` helper (line 236-247 of `compile_theme_css.rs`): +```rust +#[cfg(target_arch = "wasm32")] +async fn compile_scss( + ctx: &StageContext, + scss: &str, + load_paths: &[PathBuf], + minified: bool, +) -> Result { + ctx.runtime + .compile_sass(scss, load_paths, minified) + .await + .map_err(|e| e.to_string()) +} +``` + +This calls `SystemRuntime::compile_sass()`. Check `WasmRuntime`'s impl of +this method. It likely bridges to a JS function. Verify it's wired up and +actually called. The old JS-side `compileAndInjectThemeCss` also used SASS +compilation and worked — so SASS is available, but maybe the runtime context +differs. + +### Step 4: Check `assemble_theme_scss` on WASM + +`assemble_theme_scss` in `quarto-sass` resolves theme files. On WASM, custom +theme resolution uses VFS. Built-in themes use embedded resources +(`THEMES_RESOURCES`, `BOOTSTRAP_RESOURCES`). These should work identically +on both platforms, but verify. + +### Step 5: Check artifact flow from pipeline to VFS + +In `crates/wasm-quarto-hub-client/src/lib.rs` lines 721-727: +```rust +for (_key, artifact) in ctx.artifacts.iter() { + if let Some(artifact_path) = &artifact.path { + runtime.add_file(artifact_path, artifact.content.clone()); + } +} +``` + +Verify the `css:default` artifact has a `path` set. It should — both +`store_default_css` and `store_css` in `compile_theme_css.rs` use +`.with_path(PathBuf::from(DEFAULT_CSS_ARTIFACT_PATH))` where +`DEFAULT_CSS_ARTIFACT_PATH = "/.quarto/project-artifacts/styles.css"`. + +### Step 6: Check CSS resolution in smoke-all test + +The test reads CSS from VFS via `` hrefs in the HTML. When +`HtmlRenderConfig::default()` is used (WASM path), `css_paths` is empty, +so `ApplyTemplateStage` uses `DEFAULT_CSS_ARTIFACT_PATH` as the href. +The test resolver at `smokeAll.wasm.test.ts:423`: +```typescript +const vfsPath = href.startsWith('/') ? href : `/project/${href}`; +``` +For `/.quarto/project-artifacts/styles.css`, this keeps the path as-is. + +## Key Files + +- `crates/quarto-core/src/stage/stages/compile_theme_css.rs` — the stage +- `crates/quarto-core/src/pipeline.rs` — pipeline builders, `DEFAULT_CSS_ARTIFACT_PATH` +- `crates/quarto-core/src/stage/stages/metadata_merge.rs` — metadata merge +- `crates/wasm-quarto-hub-client/src/lib.rs:648-765` — `render_qmd` function +- `crates/quarto-system-runtime/src/wasm.rs` — `WasmRuntime` impl +- `hub-client/src/services/smokeAll.wasm.test.ts` — WASM test runner +- `crates/quarto/tests/smoke-all/metadata/theme-inheritance/` — test fixtures (untracked) + +## Recommended Approach + +1. Write a minimal focused WASM test (in `hub-client/src/services/`) that: + - Adds `_quarto.yml` with `theme: darkly` and a bare `doc.qmd` to VFS + - Calls `render_qmd()` + - Reads `/.quarto/project-artifacts/styles.css` from VFS + - Logs the first 500 chars of the CSS + - Asserts it contains `#375a7f` (darkly's primary color) + +2. If the CSS is `DEFAULT_CSS`, add `console.log` instrumentation in the + Rust `CompileThemeCssStage::run()` using `web_sys::console::log_1` + (available in the WASM crate) to trace which path is taken. + +3. Fix the root cause. Likely candidates: + - `compile_sass` bridge not working in pipeline context + - `MetadataMergeStage` not finding/merging `_quarto.yml` theme + - `assemble_theme_scss` failing on WASM for path resolution reasons + +4.

Only the +6 WASM smoke-all theme-inheritance tests fail. + +## Root Cause (Resolved) + +The WASM smoke-all test (`smokeAll.wasm.test.ts`) loaded the WASM module +directly without calling `setVfsCallbacks()` on the SASS bridge.

This commit restores and refines those features: - Move SCSS_RESOURCES_HASH from wasm-quarto-hub-client/build.rs to quarto-sass/build.rs so both native and WASM share one build-time hash - Replace DefaultHasher with SHA-256 in cache_key() - Compute cache key from theme specs + custom file contents before assembly, so cache hits skip assemble_theme_scss entirely - Add LRU eviction (200 entries / 50MB) with touch-on-read to IndexedDB cache.js - Remove dead SassCacheManager code: sassCache.ts, sassCache.test.ts, SassCacheEntry type, and unused WASM exports (compileScss, get_scss_resources_version, etc.) - Add smoke-all test fixture for theme array (vapor + custom.scss) --- Cargo.lock | 2 + .../2026-03-10-sass-cache-key-refinement.md | 268 +++++++++ crates/quarto-core/Cargo.toml | 1 + .../src/stage/stages/compile_theme_css.rs | 430 +++++++++++++- crates/quarto-sass/Cargo.toml | 3 + .../build.rs | 17 +- crates/quarto-sass/src/lib.rs | 8 + .../smoke-all/themes/theme-array/_quarto.yml | 2 + .../smoke-all/themes/theme-array/custom.scss | 4 + .../themes/theme-array/theme-array.qmd | 20 + crates/wasm-quarto-hub-client/Cargo.lock | 3 +- crates/wasm-quarto-hub-client/Cargo.toml | 3 - crates/wasm-quarto-hub-client/src/lib.rs | 30 - hub-client/src/services/sassCache.test.ts | 315 ---------- hub-client/src/services/sassCache.ts | 551 ------------------ hub-client/src/services/storage/index.ts | 1 - hub-client/src/services/storage/migrations.ts | 18 +- hub-client/src/services/storage/types.ts | 24 - hub-client/src/services/wasmRenderer.ts | 328 +---------- hub-client/src/test-utils/mockWasm.ts | 11 - .../src/types/wasm-quarto-hub-client.d.ts | 1 - hub-client/src/wasm-js-bridge/cache.d.ts | 11 +- hub-client/src/wasm-js-bridge/cache.js | 116 +++- hub-client/src/wasm-js-bridge/cache.test.ts | 86 +++ 24 files changed, 920 insertions(+), 1333 deletions(-) create mode 100644 claude-notes/plans/2026-03-10-sass-cache-key-refinement.md rename crates/{wasm-quarto-hub-client => quarto-sass}/build.rs (79%) create mode 100644 crates/quarto/tests/smoke-all/themes/theme-array/_quarto.yml create mode 100644 crates/quarto/tests/smoke-all/themes/theme-array/custom.scss create mode 100644 crates/quarto/tests/smoke-all/themes/theme-array/theme-array.qmd delete mode 100644 hub-client/src/services/sassCache.test.ts delete mode 100644 hub-client/src/services/sassCache.ts diff --git a/Cargo.lock b/Cargo.lock index e46ea40b..1f60a45d 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -3289,6 +3289,7 @@ dependencies = [ "serde", "serde_json", "serde_yaml", + "sha2 0.10.9", "tempfile", "thiserror 2.0.18", "tokio", @@ -3469,6 +3470,7 @@ dependencies = [ "regex", "serde", "serde_json", + "sha2 0.10.9", "thiserror 2.0.18", "yaml-rust2", ] diff --git a/claude-notes/plans/2026-03-10-sass-cache-key-refinement.md b/claude-notes/plans/2026-03-10-sass-cache-key-refinement.md new file mode 100644 index 00000000..49905cda --- /dev/null +++ b/claude-notes/plans/2026-03-10-sass-cache-key-refinement.md @@ -0,0 +1,268 @@ +# SASS Cache Key Refinement + +**Branch**: `feature/project-metadata` +**Plan file**: `claude-notes/plans/2026-03-10-sass-cache-key-refinement.md` +**Symlinked from**: `claude-notes/plans/CURRENT.md` + +## Session Guide + +This plan spans multiple sessions.

This is what real users hit. +- **`ts-packages/sync-test-harness/src/server-manager.ts`** — `startHubServer()` + spawns the hub as a child process with temp data dir, readiness polling, and cleanup. +- **`ts-packages/sync-test-harness/src/sync-test-helpers.ts`** — `createTestProject()` + uses `@quarto/quarto-sync-client` to create Automerge projects on the server. + +The E2E `globalSetup` should use `startHubServer()` instead of inventing a new +sync server implementation. No new npm dependency is needed. + +### Pre-seed IndexedDB for project loading + +After creating the Automerge project on the server (Node.js side), the test must +also register the project in hub-client's IndexedDB (`projectStorage`). Without this, +navigating to a share URL would trigger the connect dialog UI flow, which is fragile +and not what we're testing. + +Strategy: use `page.evaluate()` to call `projectStorage.addProject()` with the +`indexDocId` and `syncServer` URL, then navigate to the project by its local ID. +This exercises the full Automerge sync → VFS → render → preview pipeline while +skipping only the manual "connect to project" dialog. + +### Dynamic fixture creation (not pre-generated) + +Smoke-all fixtures are living source files that change with the codebase. +Pre-generating Automerge snapshots would require a regeneration step every time +a fixture changes. Instead, we create Automerge projects dynamically at test time +by reading files from disk and pushing them through the sync server. + +### URL-based navigation (not sidebar clicks) + +Navigate to files via `#/project//file/` rather than clicking +through the sidebar. This is more robust, faster, and still exercises the full +Automerge → VFS → render → preview pipeline.

No polyfill needed. The existing +`sync-test-harness` already uses this from Node.js vitest. + +### Per-test project creation + +Each smoke-all test creates its own Automerge project. This is slower than +sharing projects but avoids ordering dependencies and VFS contamination. +Start with this approach and optimize only if performance is a problem. + +## Open questions + +1. **Project creation timing**: After creating an Automerge project on the server + via `quarto-sync-client`, the creator must disconnect and the data must be + persisted before the browser connects. The existing `sync-test-helpers.ts` uses + a 2-second sleep after creation. Need to verify this is sufficient or find a + more deterministic signal. + +2. **VFS access from page.evaluate**: The wasmRenderer module is in ES module scope. + We've confirmed that `await import('/src/services/wasmRenderer.ts')` works via + Vite's dev server. Need to verify this works reliably for reading VFS and + diagnostics. + +3. **Parallel test isolation**: Each smoke-all test creates its own Automerge + project with a unique indexDocId. But the hub-client app has module-level VFS + state. If tests run in parallel (different browser contexts), each gets its own + WASM instance and VFS. Need to verify Playwright's parallel workers give proper + isolation. + +4. **Hub server compilation time**: The first `cargo run --bin hub` in CI may need + to compile. The existing `server-manager.ts` uses a 120s timeout for this. In + the E2E `globalSetup`, we should either pre-build the binary or use a similarly + generous timeout. diff --git a/hub-client/e2e/helpers/fixtureSetup.ts b/hub-client/e2e/helpers/fixtureSetup.ts index 4563ead8..027f7a2a 100644 --- a/hub-client/e2e/helpers/fixtureSetup.ts +++ b/hub-client/e2e/helpers/fixtureSetup.ts @@ -8,8 +8,12 @@ */ import { copyFileSync, mkdirSync, mkdtempSync, readdirSync, rmSync, statSync } from 'fs'; -import { join } from 'path'; +import { dirname, join } from 'path'; import { tmpdir } from 'os'; +import { fileURLToPath } from 'url'; + +const __filename = fileURLToPath(import.meta.url); +const __dirname = dirname(__filename); const FIXTURE_SOURCE_DIR = join(__dirname, '../fixtures/automerge-data'); diff --git a/hub-client/e2e/helpers/globalSetup.ts b/hub-client/e2e/helpers/globalSetup.ts index b8de3a4c..6b14358b 100644 --- a/hub-client/e2e/helpers/globalSetup.ts +++ b/hub-client/e2e/helpers/globalSetup.ts @@ -2,43 +2,46 @@ * Playwright Global Setup * * Runs once before all E2E tests: - * 1.

Project _quarto.yml !path values are now rebased to document directory in MetadataMergeStage, matching the existing behavior for _metadata.yml. This fixes subdirectory documents not inheriting project-level custom SCSS themes. 2. Added !path tags to custom SCSS references in _quarto.yml and _metadata.yml test fixtures so the path adjustment system can correctly rebase them when inherited across directories. 3. Fixed CSS color minification in test assertions: hex colors like #cc5500 get shortened to #c50 by minifiers, breaking regex matches. Replaced with non-condensable values (#cc5501, #aabb12, #112234). New smoke-all test fixtures for SCSS theme inheritance: - theme-project-scss: project-level custom SCSS (root + subdirectory) - theme-project-scss-relpath: project-level SCSS with relative paths - theme-metadata-scss: directory _metadata.yml custom SCSS - theme-metadata-scss-relpath: directory metadata SCSS with relative paths - theme-crossdir-scss: cross-directory SCSS references All 32 smoke-all tests pass across all three runners (Rust, WASM, E2E). --- claude-notes/instructions/testing.md | 1 + crates/quarto-core/src/project.rs | 2 +- .../src/stage/stages/metadata_merge.rs | 15 ++++++++++++-- .../themes/theme-crossdir-scss/_quarto.yml | 2 ++ .../chapters/crossdir-doc.qmd | 20 +++++++++++++++++++ .../theme-crossdir-scss/styles/shared.scss | 4 ++++ .../theme-metadata-scss-relpath/_quarto.yml | 2 ++ .../chapters/_metadata.yml | 3 +++ .../chapters/chapter-relpath.qmd | 14 +++++++++++++ .../chapters/deep/deep-relpath.qmd | 15 ++++++++++++++ .../chapters/styles/chapter-styles.scss | 4 ++++ .../themes/theme-metadata-scss/_quarto.yml | 2 ++ .../chapters/_metadata.yml | 3 +++ .../chapters/chapter-doc.qmd | 15 ++++++++++++++ .../chapters/custom-chapters.scss | 4 ++++ .../chapters/deep/deep-doc.qmd | 16 +++++++++++++++ .../theme-project-scss-relpath/_quarto.yml | 7 +++++++ .../chapters/subdir-relpath.qmd | 15 ++++++++++++++ .../root-relpath.qmd | 14 +++++++++++++ .../styles/custom-in-styles.scss | 4 ++++ .../themes/theme-project-scss/_quarto.yml | 7 +++++++ .../chapters/doc-inherits-project-theme.qmd | 15 ++++++++++++++ .../theme-project-scss/custom-root.scss | 4 ++++ .../themes/theme-project-scss/root-doc.qmd | 13 ++++++++++++ .../styles/project-styles.scss | 4 ++++ 25 files changed, 202 insertions(+), 3 deletions(-) create mode 100644 crates/quarto/tests/smoke-all/themes/theme-crossdir-scss/_quarto.yml create mode 100644 crates/quarto/tests/smoke-all/themes/theme-crossdir-scss/chapters/crossdir-doc.qmd create mode 100644 crates/quarto/tests/smoke-all/themes/theme-crossdir-scss/styles/shared.scss create mode 100644 crates/quarto/tests/smoke-all/themes/theme-metadata-scss-relpath/_quarto.yml create mode 100644 crates/quarto/tests/smoke-all/themes/theme-metadata-scss-relpath/chapters/_metadata.yml create mode 100644 crates/quarto/tests/smoke-all/themes/theme-metadata-scss-relpath/chapters/chapter-relpath.qmd create mode 100644 crates/quarto/tests/smoke-all/themes/theme-metadata-scss-relpath/chapters/deep/deep-relpath.qmd create mode 100644 crates/quarto/tests/smoke-all/themes/theme-metadata-scss-relpath/chapters/styles/chapter-styles.scss create mode 100644 crates/quarto/tests/smoke-all/themes/theme-metadata-scss/_quarto.yml create mode 100644 crates/quarto/tests/smoke-all/themes/theme-metadata-scss/chapters/_metadata.yml create mode 100644 crates/quarto/tests/smoke-all/themes/theme-metadata-scss/chapters/chapter-doc.qmd create mode 100644 crates/quarto/tests/smoke-all/themes/theme-metadata-scss/chapters/custom-chapters.scss create mode 100644 crates/quarto/tests/smoke-all/themes/theme-metadata-scss/chapters/deep/deep-doc.qmd create mode 100644 crates/quarto/tests/smoke-all/themes/theme-project-scss-relpath/_quarto.yml create mode 100644 crates/quarto/tests/smoke-all/themes/theme-project-scss-relpath/chapters/subdir-relpath.qmd create mode 100644 crates/quarto/tests/smoke-all/themes/theme-project-scss-relpath/root-relpath.qmd create mode 100644 crates/quarto/tests/smoke-all/themes/theme-project-scss-relpath/styles/custom-in-styles.scss create mode 100644 crates/quarto/tests/smoke-all/themes/theme-project-scss/_quarto.yml create mode 100644 crates/quarto/tests/smoke-all/themes/theme-project-scss/chapters/doc-inherits-project-theme.qmd create mode 100644 crates/quarto/tests/smoke-all/themes/theme-project-scss/custom-root.scss create mode 100644 crates/quarto/tests/smoke-all/themes/theme-project-scss/root-doc.qmd create mode 100644 crates/quarto/tests/smoke-all/themes/theme-project-scss/styles/project-styles.scss diff --git a/claude-notes/instructions/testing.md b/claude-notes/instructions/testing.md index 35a1836f..471d5862 100644 --- a/claude-notes/instructions/testing.md +++ b/claude-notes/instructions/testing.md @@ -3,6 +3,7 @@ - You are encouraged to spend time and tokens on thinking about good tests. - If writing tests is taking a lot of time, decompose the writing of tests into subtasks.

The document AST passes through unflattened. +Downstream stages looking for `doc.ast.meta["theme"]` or `doc.ast.meta["toc"]` +find nothing — those values are buried under `format.html.*`. + +### Format flattening + +`resolve_format_config()` in `crates/quarto-config/src/format.rs:72` takes a +`ConfigValue` metadata tree and a target format (e.g., "html"). It: +1. Extracts `format.{target}.*` keys +2. Merges them over top-level keys (format-specific wins) +3. Removes the `format` key from the result + +So `{ title: "Hello", format: { html: { toc: true } } }` becomes +`{ title: "Hello", toc: true }`. + +### Key types and locations + +- `ProjectContext` struct: `crates/quarto-core/src/project.rs:~344` +- `ProjectConfig` struct: `crates/quarto-core/src/project.rs:~261` + (derives `Default` — `project_type: Default`, `output_dir: None`, + `render_patterns: []`, `metadata: None`) +- `ProjectContext::discover()`: `project.rs:~368` — finds `_quarto.yml`, + creates context. Line ~404: `is_single_file = config.is_none() && input_file.is_some()` +- `ProjectContext::single_file()`: `project.rs:~433` — creates single-file + context directly, hardcodes `config: None` +- `MetadataMergeStage::run()`: `stage/stages/metadata_merge.rs:~115` +- `directory_metadata_for_document()`: `project.rs:~83` — uses + `project.config.is_none()` to early-return +- `project_type()`: `project.rs:~549` — unwraps through Option +- WASM construction: `wasm-quarto-hub-client/src/lib.rs:~486` — + `create_wasm_project_context()` hardcodes `config: None` + +### Weakened test + +`render_to_file.rs:~414` `test_render_to_file_with_theme` — renders a +single-file QMD with `format.html.theme: cosmo`. The assertion was weakened +from `assert!(css.contains(".btn"))` (compiled Bootstrap) to +`assert!(!css.is_empty())` (just checks DEFAULT_CSS fallback) because the +theme key is invisible due to this bug. Lines 442-447 have a NOTE comment +explaining this. + +## Prerequisites + +None. This is a standalone change. + +## Downstream impact + +This unblocks the migration of pipeline consumers from `Format.metadata` to +`doc.ast.meta` (see `2026-03-04-format-metadata-merge.md`). Without this +change, transforms reading flattened keys from `doc.ast.meta` would silently +get `None` in single-file renders. + +## Work Items + +### Phase 1: Tests first + +Write tests against the CURRENT (`Option`) API that demonstrate +the bug by failing. These tests will be updated in Phase 4 after the type change. + +- [x] Add test in `metadata_merge.rs`: single-file render with + `format.html.toc: true` in frontmatter and `config: None` — assert + `doc.ast.meta.get("toc")` is `Some(true)` after merge stage runs. + Currently fails because the merge gate skips flattening when config is None. +- [x] Add test in `project.rs`: `ProjectContext::discover()` for a path with + no `_quarto.yml` — assert `ctx.config.is_some()` (i.e. a default config is + present). Currently fails because `config` is `None`. +- [x] Add test in `project.rs`: `ProjectContext::single_file()` — assert + `ctx.config.is_some()`.
