Browse Source 
BREAKING CHANGE: API parameter renamed from 'extended' to 'long'

## Breaking Change: Terminology Standardization

Renamed 'extended' to 'long' across entire codebase for consistency:

**Backend (Go):**
- internal/handlers/cv.go (7 locations)
  - Migration logic to auto-convert 'extended' → 'long' cookies
  - API validation now rejects 'extended', requires 'long'
  - Toggle state logic updated
- internal/handlers/pdf_test.go (17 occurrences)
  - Test function renamed: TestExportPDF_ExtendedWithSkills → TestExportPDF_LongWithSkills
  - All test cases, parameters, and expected filenames updated
- internal/pdf/generator.go (2 comment updates)

**Frontend:**
- PDF-EXPORT-FEATURE.md (3 occurrences)
- doc/3-API.md (parameter documentation)
- doc/7-CUSTOMIZATION.md (examples updated)
- templates/partials/modals/pdf-modal.html (button text, URLs)
- static/js/main.js (migration logic)
- static/hyperscript/toggles._hs (toggle logic)
- tests/mjs/24-pdf-download-params.test.mjs (test expectations)
- tests/mjs/test-preference-migration.test.mjs (NEW)
- tests/mjs/verify-migration.test.mjs (NEW)

**PDFs Renamed:**
- cv-extended-with_skills-jamr-2025-en.pdf → cv-long-with_skills-jamr-2025-en.pdf
- cv-extended-with_skills-jamr-2025-es.pdf → cv-long-with_skills-jamr-2025-es.pdf

**Migration:** Automatic cookie migration from 'extended' → 'long' for seamless UX

## New Feature: Compact Sidebar Fonts

Reduces page count for short CV with skills from 6 → 5 pages:

**Implementation:**
- Location: internal/pdf/generator.go (lines 154-215)
- Cookie detection: `cookies["cv-length"] == "short"`
- Font reduction: 2-6% (0.94-0.98em) - very subtle
- Only activates for: `length=short` + `version=with_skills`
- Long version: Always uses full-size fonts

**Impact:**
- Page count: 6 pages → 5 pages (16.7% reduction)
- Readability: Maintained - fonts remain professional
- Design philosophy: Subtle, natural content flow

**Testing:**
- New test: TestPDFGenerator_CompactSidebarFonts
- Comprehensive coverage of cookie detection and PDF generation
- Manual verification: 5-page PDF with compact but readable fonts

**Documentation:**
- doc/LONG-PDF-GENERATION.md (NEW, 13 KB)
  - Complete feature documentation
  - Implementation details with code examples
  - Font size breakdown table
  - Testing and troubleshooting guides
  - Compact sidebar fonts section (comprehensive)

**Files Changed:**
- 11 modified (backend + frontend + docs)
- 5 new files (2 PDFs, 1 doc, 2 tests)
- 2 files renamed (PDFs)

**Tests:** All Go tests passing, API validation verified, PDF generation tested

# Long PDF Generation with Skills Sidebars
## Overview
The long PDF generation feature creates a comprehensive CV that includes technical skills sidebars positioned on the left and right sides, while hiding UI elements for a clean, print-optimized output.
**Page counts**:
- **Long version** (9 pages) - Full-size fonts, comprehensive content
- **Short version with skills** (5 pages) - Compact sidebar fonts for reduced page count
## Key Features
- **9-page layout** with optimal content density
- **25% sidebars** for skills/competencies display
- **2-column approach** matching web layout (no wasted space)
- **Page breaks** between left and right sidebar sections
- **Hidden mobile UI elements** (accordion headers, navigation)
- **Print media CSS** for compact, professional typography
## Architecture
### PDF Generation Flow
```
User clicks "Long CV (9 pages)" in PDF Modal
↓
Frontend: `/export/pdf?lang=es&length=long&icons=show&version=with_skills`
↓
Backend: GenerateFromURLWithOptions(url, cookies, RenderModeScreen)
↓
Chromedp: Navigate to URL with cookies
↓
CSS Injection: Override print.css + Show sidebars + 2-column layout
↓
PDF Generation: PrintToPDF with A4 dimensions
↓
Output: 9-page PDF with sidebars (or 5 pages with compact fonts for short version)
```
### Critical Components
#### 1. PDF Generator (`internal/pdf/generator.go`)
**RenderMode**:
- `RenderModePrint` - Clean version (hides sidebars)
- `RenderModeScreen` - Long version (shows sidebars)
**CSS Injection Strategy**:
```javascript
// Override parent width constraints (full A4 width)
'.cv-page, .cv-paper, .cv-container { max-width: 100% !important; ... }'
// Show sidebars (override print.css hiding)
'.cv-sidebar, .cv-sidebar-left, .cv-sidebar-right { display: block !important; }'
// Hide mobile UI elements
'.sidebar-accordion-header { display: none !important; }'
// Force page break before page 2
'.page-2 { page-break-before: always !important; break-before: page !important; }'
// 2-column layouts (no wasted space)
'.page-1 .page-content { grid-template-columns: 25% 75% !important; }'
'.page-2 .page-content { grid-template-columns: 75% 25% !important; }'
```
#### 2. HTML Structure (`templates/cv-content.html`)
**Page 1**: Left sidebar + Main content
```html
<div class="cv-page page-1">
<div class="page-content">
<aside class="cv-sidebar cv-sidebar-left">...</aside>
<main class="cv-main">...</main>
</div>
</div>
```
**Page 2**: Main content + Right sidebar
```html
<div class="cv-page page-2">
<div class="page-content">
<main class="cv-main">...</main>
<aside class="cv-sidebar cv-sidebar-right">...</aside>
</div>
</div>
```
#### 3. Frontend Integration (`templates/partials/modals/pdf-modal.html`)
**PDF Modal Options**:
- Short CV (4 pages) - `version=clean`
- **Long CV (9 pages)** - `version=with_skills` ← This feature
- **Short CV with skills (5 pages)** - `length=short&version=with_skills` with compact fonts
- Current View - Uses localStorage settings
## Why 2-Column Layout?
### ❌ Previous Approach (3-column - WRONG)
```css
.page-1, .page-2: 25% | 50% | 25% /* Always 3 columns */
```
- Page 1 had empty right column (25% wasted)
- Page 2 had empty left column (25% wasted)
- Result: 10-19 pages
### ✅ Current Approach (2-column - CORRECT)
```css
.page-1: 25% | 75% /* Left sidebar + Main, NO right space */
.page-2: 75% | 25% /* Main + Right sidebar, NO left space */
```
- No wasted space on either page
- Matches web's actual layout exactly
- Result: **9 pages**
## Configuration
### Sidebar Width Tuning
Sidebar width affects page count:
| Width | Layout | Pages | Notes |
|-------|--------|-------|-------|
| 18% | 18% \| 82% | 9 pages | Too narrow |
| 20% | 20% \| 80% | 8 pages | Minimal sidebars |
| **25%** | **25% \| 75%** | **9 pages** | ✅ **Current** (optimal balance) |
| 30% | 30% \| 70% | 10+ pages | Too wide |
**Current Setting**: 25% sidebars (`internal/pdf/generator.go:176,181`)
### Adjusting Sidebar Width
To change sidebar width, update two lines in `internal/pdf/generator.go`:
```go
// Page 1: Left sidebar (XX%) + Main (YY%) - NO right space
'.page-1 .page-content { ' +
'grid-template-columns: XX% YY% !important; ' +
'} ' +
// Page 2: Main (YY%) + Right sidebar (XX%) - NO left space
'.page-2 .page-content { ' +
'grid-template-columns: YY% XX% !important; ' +
'} ' +
```
Where `XX + YY = 100`
## Print Media CSS
The extended PDF uses `@media print` from `static/css/08-contexts/_print.css` for:
- Compact fonts and spacing
- Hiding UI chrome (navigation, buttons, footer)
- Professional typography
**Overridden in PDF**:
- Sidebar hiding (`.cv-sidebar { display: none }` → `display: block !important`)
- Accordion headers (`.sidebar-accordion-header { display: none !important }`)
## Testing
### Unit Tests
The long PDF feature has comprehensive test coverage in `internal/handlers/pdf_test.go`:
**Test Functions:**
1. `TestExportPDF_LongWithSkills` - Tests long PDF with multiple language/icon combinations
2. `TestPDFGenerator_RenderModes` - Tests both `RenderModePrint` and `RenderModeScreen`
3. `TestExportPDF_SkillsSidebarFeatures` - Tests specific skills sidebar features:
- Version parameter validation (`clean`, `with_skills`)
- PDF modal integration URLs
- Frontend button parameter correctness
4. `TestPDFGenerator_CompactSidebarFonts` - Tests compact font feature for short version
Run the tests:
```bash
go test ./internal/handlers -v -run TestExportPDF
```
### Integration Testing
Check page count and PDF generation:
```bash
# Download long PDF (9 pages with sidebars)
curl "http://localhost:1999/export/pdf?lang=es&length=long&icons=show&version=with_skills" -o test-long.pdf
# Download short PDF with skills (5 pages with compact fonts)
curl "http://localhost:1999/export/pdf?lang=es&length=short&icons=show&version=with_skills" -o test-short-skills.pdf
# Download short PDF clean (4 pages, no sidebars)
curl "http://localhost:1999/export/pdf?lang=es&length=short&icons=show&version=clean" -o test-short.pdf
# Verify page counts
pdfinfo test-long.pdf | grep Pages
# Expected: Pages: 9
pdfinfo test-short-skills.pdf | grep Pages
# Expected: Pages: 5
pdfinfo test-short.pdf | grep Pages
# Expected: Pages: 4
```
### Manual Verification
**Long CV (9 pages):**
1. Open http://localhost:1999 in browser
2. Click "Descargar PDF" button
3. Select "CV Largo (9 páginas)" / "Long CV (9 pages)"
4. Click "Descargar PDF"
5. Verify downloaded PDF has:
- 9 pages total
- 25% sidebars on left (page 1) and right (page 2+)
- Full-size fonts in sidebars
- No "Competencias Técnicas" accordion header visible
- Page break between page 1 and page 2
- Skills content displayed in sidebars
**Short CV with skills (5 pages with compact fonts):**
1. Toggle to short view and with_skills theme
2. Download PDF
3. Verify:
- 5 pages total
- Compact sidebar fonts (0.94-0.98em)
- All content fits naturally without overflow
- Maintained readability
## API Endpoint
**URL**: `/export/pdf`
**Query Parameters**:
- `lang` - Language (`es`, `en`)
- `length` - CV length (`short`, `long`)
- `icons` - Show icons (`show`, `hide`)
- `version` - Layout version (`clean`, `with_skills`)
**Examples**:
```bash
# Long CV with skills (9 pages, full-size fonts)
GET /export/pdf?lang=es&length=long&icons=show&version=with_skills
# Short CV with skills (5 pages, compact sidebar fonts)
GET /export/pdf?lang=es&length=short&icons=show&version=with_skills
# Short CV clean (4 pages, no sidebars)
GET /export/pdf?lang=es&length=short&icons=show&version=clean
```
## Troubleshooting
### Issue: Sidebars not showing
**Solution**: Check `RenderModeScreen` is being used (not `RenderModePrint`)
### Issue: Wrong page count
**Solution**:
1. Check sidebar width percentage (should be 25%)
2. Verify CSS injection is working
3. Check for browser console errors
### Issue: Accordion header visible
**Solution**: Ensure `.sidebar-accordion-header { display: none !important; }` in CSS injection
### Issue: No page break between pages
**Solution**: Verify `.page-2 { page-break-before: always !important; }` is applied
## Compact Sidebar Fonts Feature
### Overview
The compact sidebar fonts feature automatically reduces sidebar font sizes by 2-6% **only for short CVs with skills** (`length=short&version=with_skills`), reducing page count from 6 pages to 5 pages while maintaining excellent readability.
**Impact:**
- **Page count reduction**: 6 pages → 5 pages (16.7% reduction)
- **Font size reduction**: 2-6% (very subtle, 0.94-0.98em)
- **Readability**: Maintained - fonts remain professional and readable
- **Only for short version**: Long version uses full-size fonts
### When It Activates
The feature automatically activates when **both** conditions are met:
1. `length=short` (detected via `cv-length` cookie)
2. `version=with_skills` (RenderModeScreen with sidebars)
**Does NOT activate for:**
- Long CVs (`length=long`) - always use full-size fonts
- Clean version (`version=clean`) - no sidebars shown
- Short clean version - no sidebars to compact
### Implementation
**Location**: `internal/pdf/generator.go` (lines 154-215)
**Cookie Detection**:
```go
// Check if this is a short version (to apply compact sidebar fonts)
// The length parameter is passed as a cookie, not in the URL
isShortVersion := cookies["cv-length"] == "short"
```
**CSS Injection** (only when `isShortVersion == true`):
```go
compactFontCSS := ""
if isShortVersion {
compactFontCSS = ` +
// Compact sidebar fonts (SHORT VERSION ONLY) - very subtle reduction
'.cv-sidebar * { font-size: 0.96em !important; line-height: 1.4 !important; } ' +
'.cv-sidebar h3 { font-size: 0.98em !important; margin: 0.4em 0 !important; } ' +
'.cv-sidebar h4 { font-size: 0.96em !important; margin: 0.35em 0 !important; } ' +
'.cv-sidebar p, .cv-sidebar li { font-size: 0.94em !important; line-height: 1.4 !important; } ' +
'.cv-sidebar ul, .cv-sidebar ol { margin: 0.4em 0 0.4em 1.2em !important; } ' +
'.cv-sidebar li { margin-bottom: 0.25em !important; } ' +
'.cv-sidebar section { margin-bottom: 0.8em !important; } '`
}
```
### Font Size Breakdown
| Element | Full-Size (Long) | Compact (Short) | Reduction |
|---------|------------------|-----------------|-----------|
| General text | 1.0em | 0.96em | 4% |
| H3 headings | 1.0em | 0.98em | 2% |
| H4 headings | 1.0em | 0.96em | 4% |
| Paragraphs & lists | 1.0em | 0.94em | 6% |
**Line height**: Consistent 1.4 for improved readability
### Design Philosophy
**Why subtle reduction?**
1. **Readability first**: 2-6% reduction is barely noticeable
2. **Professional appearance**: No "squeezed" or cramped feel
3. **Natural flow**: Content reflows organically, not forced
4. **Consistent UX**: Main content uses full-size fonts
**Why only short version?**
- Short CV has less content → compact fonts sufficient
- Long CV needs maximum readability for extensive content
- Consistent with "short = concise, long = comprehensive" semantics
### Testing
**Test function**: `TestPDFGenerator_CompactSidebarFonts` in `internal/handlers/pdf_test.go`
**Test coverage:**
1. Cookie-based detection (`cv-length=short` vs `cv-length=long`)
2. PDF generation with compact fonts
3. Version parameter validation (`with_skills` vs `clean`)
4. Page count verification (5 pages for short with skills)
**Run tests**:
```bash
go test ./internal/handlers -v -run TestPDFGenerator_CompactSidebarFonts
```
### Manual Verification
1. Navigate to http://localhost:1999
2. Toggle to **short view** (localStorage: `cv-length=short`)
3. Toggle to **with_skills theme** (localStorage: `cv-theme=default` or `with_skills`)
4. Download PDF
5. Verify:
- **5 pages total** (not 6)
- Sidebar fonts slightly smaller than main content
- Still professional and readable
- No content overflow or truncation
**Compare with long version:**
1. Toggle to **long view** (`cv-length=long`)
2. Download PDF
3. Verify:
- **9 pages total**
- Sidebar fonts same size as short version main content
- Full-size fonts throughout
### Troubleshooting
#### Issue: Short PDF still has 6 pages
**Solution**:
1. Verify `cv-length` cookie is set to `short` (check browser DevTools)
2. Ensure `isShortVersion` detection works in generator.go:156
3. Check CSS injection is applied (add debug logging)
#### Issue: Fonts too small or hard to read
**Solution**:
1. Adjust font size percentages in generator.go:206-214
2. Increase from 0.94em to 0.96em for paragraphs
3. Test with actual content to verify readability
#### Issue: Long version also has compact fonts
**Solution**:
1. Check cookie detection logic - must be `cookies["cv-length"] == "short"`
2. Verify compactFontCSS is only appended when `isShortVersion == true`
3. Ensure long version passes `cv-length=long` cookie
## Future Improvements
- [ ] Make sidebar width configurable via query parameter
- [ ] Add option to customize page break positioning
- [ ] Support for different paper sizes (Letter, Legal)
- [ ] Transparent background option
- [ ] Custom padding/margin configuration
