Here's what they mean and how to fix them. + +### Rule 1: CODE_LANG_TAG + +**What it checks:** All fenced code blocks (3+ backticks) must have a language tag. + +**Why it matters:** Bare code blocks silently fail syntax highlighting and can cause Quarto render errors. + +#### Examples + +❌ **Bad: Bare code block** + +```qmd +Here's some R code: + +``` +x <- rnorm(100) +mean(x) +``` + +**Problem:** Quarto doesn't know this is R code → no syntax highlighting, no execution. +``` + +✅ **Good: Tagged code block** + +```qmd +Here's some R code: + +```{r} +x <- rnorm(100) +mean(x) +``` + +**Works:** Quarto recognizes R → highlights syntax, executes code. +``` + +✅ **Alternative: Non-executable text** + +```qmd +Here's pseudocode: + +```{.text} +FOR i = 1 to 100 + PRINT i +END +``` + +**Works:** Tagged as text → renders as preformatted block. +``` + +#### Common Tags + +| Tag | Use Case | +|-----|----------| +| `{r}` | R code (executable) | +| `{python}` | Python code (executable) | +| `{bash}` | Shell commands (executable) | +| `{.text}` | Plain text (non-executable) | +| `{.output}` | Command output examples | + +### Rule 2: DIV_BALANCE + +**What it checks:** All `:::` div openers must have matching `:::` closers. + +**Why it matters:** Unclosed divs corrupt page layout and break nested content rendering. + +#### Examples + +❌ **Bad: Unclosed div** + +```qmd +::: {.callout-note} +This is important information. + + +Next section starts here. +``` + +**Problem:** "Next section" gets swallowed into the callout div. + +✅ **Good: Balanced divs** + +```qmd +::: {.callout-note} +This is important information. +::: + +Next section starts here. +``` + +❌ **Bad: Nested divs closed in wrong order** + +```qmd +::: {.column-page} +::: {.callout-tip} +Nested content +::: +::: +``` + +✅ **Good: Proper nesting** + +```qmd +::: {.column-page} +::: {.callout-tip} +Nested content +::: +::: +``` + +**Tip:** Match divs like parentheses - inner closes before outer. + +### Rule 3: CALLOUT_VALID + +**What it checks:** Callout divs use valid Quarto callout types. + +**Why it matters:** Invalid callout types render as unstyled divs, breaking visual hierarchy. + +#### Valid Callout Types + +Quarto supports exactly 5 callout types: + +| Type | Purpose | Icon | +|------|---------|------| +| `note` | General information | 📝 | +| `tip` | Helpful suggestions | 💡 | +| `important` | Key concepts | ❗ | +| `warning` | Cautions | ⚠️ | +| `caution` | Danger/risk | 🚨 | + +#### Examples + +❌ **Bad: Invalid callout type** + +```qmd +::: {.callout-info} + +This won't be styled correctly. +::: +``` + +✅ **Good: Valid callout type** + +```qmd +::: {.callout-note} + +This renders with proper styling. +::: +``` + +**Common mistakes:** + +- `.callout-info` → Use `.callout-note` instead +- `.callout-danger` → Use `.callout-caution` instead +- `.callout-success` → Use `.callout-tip` instead + +### Rule 4: HEADING_HIERARCHY + +**What it checks:** Headings follow sequential levels (no skipped levels). + +**Why it matters:** Broken hierarchy confuses navigation, screen readers, and document structure. + +#### Examples + +❌ **Bad: Skipped heading level** + +```qmd +# Week 1: Introduction +### Subsection A (skipped ##) +#### Detail +``` + +**Problem:** Jump from H1 → H3 breaks document outline. + +✅ **Good: Sequential hierarchy** + +```qmd +# Week 1: Introduction +## Section A +### Subsection A +#### Detail +``` + +❌ **Bad: Multiple H1s in same file** + +```qmd +# Week 1: Introduction +# Week 2: Foundations (should be ##) +``` + +**Problem:** Multiple top-level headings fragment document structure. + +✅ **Good: One H1, structured sections** + +```qmd +# Week 1 & 2: Foundations +## Week 1: Introduction +## Week 2: Core Concepts +``` + +**Tip:** Reserve `#` (H1) for document title, use `##` (H2) for main sections. + +--- + +## Common Patterns & Fixes + +Real-world scenarios from stat-545 and stat-579 migrations. + +### Pattern 1: Lots of Bare Code Blocks + +**Scenario:** You've been using bare blocks for years, now have 100+ violations. + +**Diagnosis:** + +```bash +# Find all bare code blocks +cd ~/teaching/stat-545 +grep -n "^\`\`\`$" lectures/*.qmd + +# Example output: +# lectures/week-01.qmd:45:``` +# lectures/week-01.qmd:48:``` +# lectures/week-02.qmd:23:``` +# ... +``` + +**Fix Strategy A: Bulk tag as R code** + +```bash +# For files with mostly R code, tag all bare blocks as {r} +# WARNING: Review first, this replaces ALL bare blocks + +# Dry run (shows changes without applying) +sed -n 's/^```$/```{r}/p' lectures/week-01.qmd + +# Apply changes +sed -i '' 's/^```$/```{r}/' lectures/week-01.qmd +``` + +**Fix Strategy B: Manual review (recommended)** + +```bash +# Use lint to find violations +teach validate --lint lectures/week-01.qmd + +# Open file, jump to line number +vim +45 lectures/week-01.qmd +# Or use your preferred editor +``` + +Then tag appropriately: + +- R code → `{r}` +- Python → `{python}` +- Shell → `{bash}` +- Plain text → `{.text}` + +### Pattern 2: Unbalanced Divs from Copy-Paste + +**Scenario:** You copied a callout from another file, forgot the closing `:::`. + +**Diagnosis:** + +```bash +# Lint shows exact line number +teach validate --lint lectures/week-03.qmd + +# Output: +# ❌ DIV_BALANCE: 1 unclosed div +# Line 92: Unclosed div (add closing :::) +``` + +**Fix:** + +```bash +# Open at line 92 +vim +92 lectures/week-03.qmd +``` + +Use your editor's bracket matching (if supported) or manually count: + +```qmd +::: {.callout-note} # Line 92: Opener +Content here. + +``` + +**Count trick:** + +```bash +# Count openers vs closers +grep -c "^:::" lectures/week-03.qmd # Total ::: lines +grep -c "^::: {" lectures/week-03.qmd # Openers only + +# Should be equal or 2x (if closers are also :::) +``` + +### Pattern 3: Custom Callout Types + +**Scenario:** You've been using `.callout-info` or `.callout-success` in your materials. + +**Decision Point:** Convert to standard types OR disable the rule. + +#### Option A: Convert to Standard Types (Recommended) + +```bash +# Find all custom callout types +grep -n "\.callout-info" lectures/*.qmd + +# Convert .callout-info → .callout-note +sed -i '' 's/\.callout-info/.callout-note/g' lectures/*.qmd + +# Convert .callout-success → .callout-tip +sed -i '' 's/\.callout-success/.callout-tip/g' lectures/*.qmd +``` + +#### Option B: Disable LINT_CALLOUT_VALID (Not Recommended) + +If you have custom Quarto extensions that define additional callout types: + +```bash +# Skip callout validation for specific files +teach validate --lint --validators lint-shared lectures/week-custom.qmd +# (Future: custom validator configs) +``` + +**Trade-off:** Disabling the rule means you won't catch typos like `.callout-notte`. + +### Pattern 4: Heading Hierarchy Issues + +**Scenario:** You've been using `###` for all subheadings, regardless of nesting. + +**Diagnosis:** + +```bash +teach validate --lint lectures/week-05.qmd + +# Output: +# ❌ HEADING_HIERARCHY: Skipped heading level +# Line 34: H3 follows H1 (expected H2) +``` + +**Fix:** Restructure headings sequentially: + +```qmd + +# Week 5: Regression +### Model Assumptions (skipped H2) +### Diagnostics (skipped H2) + + +# Week 5: Regression +## Model Assumptions +## Diagnostics +``` + +**Mass fix strategy:** + +```bash +# Downgrade all H3 → H2 (review first!) +sed -i '' 's/^### /## /' lectures/week-05.qmd +``` + +--- + +## Configuration Options + +Customize lint behavior for your workflow. + +### Run Lint on Specific Files + +```bash +# Single file +teach validate --lint lectures/week-01-intro.qmd + +# Multiple files (glob pattern) +teach validate --lint lectures/week-*.qmd + +# All .qmd files recursively +teach validate --lint **/*.qmd +``` + +### Quiet Mode (For CI/CD) + +```bash +# Suppress detailed output, return only exit code +teach validate --lint --quiet lectures/week-01.qmd + +# Exit code 0 = pass, non-zero = violations found +echo $? +``` + +**Use case:** GitHub Actions, pre-commit hooks that need pass/fail only. + +### Quick Checks Only + +```bash +# Run lint-shared validator only (fastest) +teach validate --lint --quick-checks lectures/week-01.qmd + +# Alias for: --validators lint-shared +``` + +**Performance:** ~50% faster on large files, runs core lint rules only. + +### Custom Validators (Future) + +```bash +# Coming in v5.25.0: Specify validator plugins +teach validate --validators lint-shared,lint-slides lectures/slides.qmd +``` + +**Planned validators:** + +- `lint-slides` - RevealJS-specific checks +- `lint-accessibility` - WCAG compliance +- `lint-citations` - BibTeX validation + +--- + +## Workflow Integration + +Integrate lint into your existing teaching workflow. + +### Pre-Commit Hook (Warn-Only Mode) + +**Goal:** Run lint on staged `.qmd` files before commit, warn about issues without blocking. + +**Setup:** + +```bash +# 1. Create hooks directory +mkdir -p .teach/hooks + +# 2. Create pre-commit hook +cat > .teach/hooks/pre-commit << 'EOF' +#!/bin/bash +# Lint staged .qmd files (warn, don't block) + +echo "🔍 Running lint checks on staged .qmd files..." + +changed_files=$(git diff --cached --name-only --diff-filter=ACM | grep '\.qmd$') + +if [[ -n "$changed_files" ]]; then + teach validate --lint --quiet $changed_files || true + # || true = warn but never block commit + + if [[ $? -ne 0 ]]; then + echo "" + echo "⚠️ Lint violations found (see above)" + echo "💡 Tip: Fix with 'teach validate --lint '" + echo "⏩ Continuing with commit (violations not blocking)" + echo "" + fi +fi +EOF + +# 3. Make executable +chmod +x .teach/hooks/pre-commit + +# 4. Link to git hooks +ln -sf ../../.teach/hooks/pre-commit .git/hooks/pre-commit +``` + +**Usage:** Violations display as warnings but never block your commit. + +**To upgrade to blocking mode:** Remove `|| true` from the hook. + +### CI/CD Integration (GitHub Actions) + +**Goal:** Run lint checks on every push/PR to catch issues before merge. + +**Setup:** + +```yaml +# .github/workflows/lint.yml +name: Lint Course Content + +on: + push: + branches: [main, dev] + pull_request: + branches: [main] + +jobs: + lint: + runs-on: ubuntu-latest + steps: + - name: Checkout code + uses: actions/checkout@v3 + + - name: Install flow-cli + run: | + brew tap data-wise/tap + brew install flow-cli + + - name: Run lint on lectures + run: | + teach validate --lint lectures/*.qmd + + - name: Run lint on labs + run: | + teach validate --lint labs/*.qmd +``` + +**Result:** PR checks show pass/fail status, blocking merge if violations found. + +### Watch Mode (Future) + +**Coming in v5.25.0:** Auto-run lint on file changes. + +```bash +# Planned feature +teach validate --lint --watch + +# Expected behavior: +# 👀 Watching lectures/*.qmd for changes... +# 🔄 week-01.qmd changed → running lint... +# ✅ No violations found +``` + +**Use case:** Keep lint check running in terminal while editing in IDE. + +--- + +## Migration Strategies + +Choose the approach that fits your timeline and course schedule. + +### Strategy 1: Big Bang (1-2 Hours) + +**Best for:** Small courses (< 20 files), semester break, motivated instructors. + +**Timeline:** Complete migration in one sitting. + +**Steps:** + +```bash +# 1.

tests/interactive-dog-lint.zsh +``` + +--- + +## Test Maintenance + +### Adding New Rules (Phase 2+) + +When adding new lint rules: + +1. **Unit test** - Add to `test-lint-shared-unit.zsh`: + - Positive case (detects error) + - Negative case (passes clean file) + +2. **E2E test** - Add to `test-lint-e2e.zsh`: + - Test in combination with other rules + - Test with --quick-checks if applicable + +3. **Integration** - Update `test-lint-integration.zsh`: + - Add to expected output if rule commonly triggers + +4. **Dogfooding** - Update `interactive-dog-lint.zsh`: + - Add task for manual verification + +### Test Fixtures + +Location: `tests/fixtures/lint/*.qmd` + +Current fixtures: +- `bare-code-block.qmd` - Code blocks without language tags +- `unbalanced-divs.qmd` - Unclosed fenced divs +- `bad-callout.qmd` - Invalid callout types +- `skipped-headings.qmd` - Heading hierarchy violations + +--- + +## Future Improvements + +### Test Enhancements + +1. **Fix E2E test issues:** + - Adjust auto-discovery test expectations + - Update quiet mode test for actual output format + - Fix help text test command name + +2. **Add snapshot tests:** + - Capture expected output format + - Detect unintended output changes + +3. **Add coverage reporting:** + - Track which validator code paths are exercised + - Identify untested edge cases + +4. **Performance benchmarks:** + - Set baseline performance metrics + - Detect performance regressions + +### Documentation + +1. **Test writing guide** - How to add tests for new rules +2. **CI integration** - Run tests on pull requests +3. **Test data generator** - Create realistic .qmd fixtures + +--- + +## Success Criteria + +✅ **Met:** +- 9/9 unit tests passing (100%) +- 7/10 E2E tests passing (70%, 3 minor issues) +- Integration
