Pagination and Template Metadata Fixes

Summary

Fixed all issues from todo.md related to template metadata, pagination capacities, and empty row filling.

Changes Made

1. Dynamic Capacity Loading (✓ COMPLETED)

Problem: PreparePaginatedPageData hardcoded capacity values that didn't match template MAX values.

Solution:

• Added GetBlockCapacity() helper function to read MAX from template metadata
• Updated PreparePaginatedPageData() to dynamically load capacities for all pages
• Removed all hardcoded capacity values (24, 11, 5, 30, 20, 10, etc.)

Files Modified:

• pagination_helper.go: Added GetBlockCapacity(), updated all page handlers

2. Page2 Pagination Fixed (✓ COMPLETED)

Problem:

• skills_learned used capacity 24 instead of template's MAX:18
• skills_languages used capacity 11 instead of template's MAX:5
• weapons_main capacity was inconsistent

Solution:

• Page2 now reads correct capacities from template:
  • skills_learned: MAX:18 (was 24)
  • skills_unlearned: MAX:15 (correct)
  • skills_languages: MAX:5 (was 11)
  • weapons_main: MAX:24 (was 30)

Template Values (from page2_play.html):

<!-- BLOCK: skills_learned, TYPE: skills, MAX: 18, FILTER: learned -->
<!-- BLOCK: skills_unlearned, TYPE: skills, MAX: 15, FILTER: unlearned -->
<!-- BLOCK: skills_languages, TYPE: skills, MAX: 5, FILTER: language -->
<!-- BLOCK: weapons_main, TYPE: weapons, MAX: 24 -->

3. Page3 Magic Items Fixed (✓ COMPLETED)

Problem: magic_items used capacity 5 instead of template's MAX:8

Solution: Updated to read from template (MAX:8)

Template Values (from page3_spell.html):

<!-- BLOCK: spells_left, TYPE: spells, MAX: 26 -->
<!-- BLOCK: spells_right, TYPE: spells, MAX: 15 -->
<!-- BLOCK: magic_items, TYPE: magicItems, MAX: 8 -->

4. Page4 Equipment Fixed (✓ COMPLETED)

Problem: Used wrong block name ("equipment" instead of "equipment_worn")

Solution: Updated to use correct block name from template

Template Values (from page4_equip.html):

<!-- BLOCK: equipment_worn, TYPE: equipment, MAX: 10, FILTER: worn -->

5. Tests Updated (✓ COMPLETED)

Problem: Tests hardcoded expected MAX values instead of reading from templates

Solution: Updated all tests to dynamically read capacities:

• TestPaginationUsesTemplateMetadata: Verifies template parsing works
• TestPage2PaginationWithCorrectCapacities: Uses GetBlockCapacity()
• TestPage3MagicItemsCapacity: Uses GetBlockCapacity()
• TestPreparePaginatedPageData_Page3Spell: Updated expectations
• TestPreparePaginatedPageData_Page4Equipment: Fixed block name
• TestCalculatePagesNeeded: Updated to match template capacities (24 not 30, 41 not 30)
• TestPaginateSpells_MultiPage: Updated to 26+15=41
• TestPaginateWeapons_MultiPage: Updated to 24 capacity (3 pages for 50 weapons)
• TestIntegration_TemplateMetadata: Updated expected values
• templates_test.go: Updated TestGetTemplateMetadata expectations
• template_metadata_loader_test.go: Updated expected values

Files Modified:

• todo_fixes_test.go: New test file with TDD tests
• pagination_helper_test.go: Updated expectations
• pagination_test.go: Updated test cases
• integration_test.go: Updated expected block MAX values
• templates_test.go: Updated to expect 26/15 not 20/10
• template_metadata_loader_test.go: Updated to expect 26 not 20

Test Results

70 tests passing
0 tests failing

All pdfrender tests pass:
- 13 pagination tests
- 8 template metadata tests
- 6 fill_capacity tests
- 9 mapper tests
- 17 integration tests
- 4 new todo_fixes tests
- 13 other tests

Visual Verification

Generated test PDFs confirm:

• ✓ Page1: Skills split correctly across 2 columns (29+29)
• ✓ Page2: 18 learned skills, 5 language skills, 24 weapons
• ✓ Page3: 26 left spells, 15 right spells, 8 magic items
• ✓ Page4: 10 equipment items
• ✓ All empty rows render correctly
• ✓ Combined PDF merges all pages successfully

Weapons Implementation Note

The current implementation correctly uses Waffenfertigkeiten (weapon skills) for the weapons_main list. Each weapon skill already contains:

• Name: Weapon name (e.g., "Schwert", "Bogen")
• Value (EW): Fertigkeitswert (skill effectiveness value)
• This is the correct data for character sheet display

The Equipment.Weapons (EqWaffe) contains physical weapon objects with different metadata (Abwb, Schb, weight, etc.) which is not needed for the weapons_main table on page2.

Architecture Improvements

1. Separation of Concerns: Template metadata is now the single source of truth
2. Maintainability: Adding/changing template capacities only requires HTML comment updates
3. Type Safety: GetBlockCapacity() provides consistent interface
4. Testability: Tests verify against actual templates, not hardcoded values
5. DRY Principle: No duplication between template definitions and code

Future Enhancements

All current issues resolved. System ready for:

• Multi-page pagination (already working for >58 skills, >24 weapons, >41 spells)
• Additional template blocks (just add HTML comments)
• Different template sets (already supported via LoadTemplateSetFromFiles)
