DeckUse Project Status

Generated: 2026-03-30 Status: Phase 1 Infrastructure Complete ✅

What's Been Implemented

✅ Project Infrastructure

  • npm package configuration with TypeScript + ESM
  • Build system using tsup
  • Test framework (vitest) with sample tests
  • Git ignore configuration
  • Directory structure following the plan

✅ Core Modules

Workspace Management (src/core/workspace.ts)

  • Workspace initialization and loading
  • Metadata storage in .deckuse/metadata.json
  • Status checking and validation
  • Index management for slides, shapes, and layouts

Selector System (src/core/selector.ts)

  • Parser for selector expressions
  • Resolver to find targets in workspace
  • Supported syntax:
    • slide:3 - indexed selection
    • slide:3/title - path-based selection
    • shape[type=textbox] - filtered selection
    • text[contains('keyword')] - text search

Type System (src/core/types.ts)

  • Complete type definitions for all core concepts
  • Interfaces for workspace, slides, shapes, selectors, etc.

Error Handling (src/utils/errors.ts)

  • Custom error classes with clear messages
  • Specific errors for different failure scenarios

Logging (src/utils/logger.ts)

  • Configurable logging utility
  • Support for different log levels

✅ Commands Implemented

All commands have scaffolding in place:

Core Workflow:

  • init - Initialize workspace from PPTX
  • status - Show workspace status
  • commit - Build PPTX from workspace

Read Commands:

  • list slides - List all slides
  • show slide - Show slide details
  • get text - Get text content

Write Commands (S0 - Safe Operations):

  • set text - Replace text in shapes
  • replace text - Global find and replace
  • set font-size - Set font size

✅ CLI Interface

  • Commander-based CLI (src/cli.ts)
  • All commands registered and working
  • Proper error handling and user feedback
  • Binary entry point configured

✅ Testing

  • Unit tests for selector parsing
  • Unit tests for workspace management
  • Integration test scaffold (skipped until PPTX libraries available)
  • All tests passing ✅

What's NOT Yet Implemented

🚧 PPTX Integration

The following components have placeholder implementations and need actual library integration:

PPTX Reader (src/readers/pptx-reader.ts)

Status: Stub implementation, returns empty/null data

Needs:

  • Integration with @deckflow/presentation (or alternative PPTX library)
  • Actual reading of:
    • Slide structure
    • Shape information
    • Text content
    • Metadata

PPTX Writer (src/writers/pptx-writer.ts)

Status: Stub implementation, no-op methods

Needs:

  • Integration with @deckflow/pptx-modifier (or alternative PPTX library)
  • Actual implementation of:
    • Text modification
    • Font property changes
    • Shape geometry updates
    • XML file updates

📋 Missing Commands

From the README, these commands are not yet implemented:

Diagnostic Commands:

  • validate - Validate PPTX structure
  • doctor - Run heuristic checks
  • inspect - Show PPTX overview
  • tree - Show object tree
  • find - Search content
  • query - Complex selector queries
  • stats - Deck-wide statistics

Additional S0 Commands:

  • clear text
  • set run-text
  • set font-family
  • set font-color
  • set bold/italic/underline
  • set paragraph-align
  • set bullet/indent/line-spacing
  • move/set position
  • resize/rotate/flip

S1 Commands:

  • All fill/line/z-order commands
  • Image manipulation commands
  • Notes commands

S2 Commands:

  • All destructive operations with confirmation

Critical Next Steps

1. PPTX Library Integration (HIGHEST PRIORITY)

Problem: The specified libraries don't exist in npm:

  • @deckflow/presentation
  • @deckflow/pptx-modifier

Options:

Option A: Find the correct library names

  • Are these libraries published under different names?
  • Are they private packages?
  • Do they need to be built from source?

Option B: Use alternative PPTX libraries

  • PptxGenJS - Popular PPTX generation library
  • officegen - Office document generation
  • node-pptx - PPTX manipulation
  • Direct XML manipulation using JSZip + xml2js

Recommendation: Determine if @deckflow/* packages exist or choose an alternative approach.

2. Implement Core PPTX Operations

Once libraries are available:

  1. Update PptxReader:

    • Implement readSlides() to extract slide information
    • Implement readShapes() to get shape data
    • Implement readText() to extract text
    • Update buildIndexes() in init command

  2. Update PptxWriter:

    • Implement setText() for text modification
    • Implement setFontSize() and other font operations
    • Implement replaceText() for find/replace
    • Implement save() to persist changes

  3. Test Full Workflow:

    • Create test PPTX file
    • Test: init → set text → commit
    • Verify output PPTX opens correctly

3. Expand Command Coverage

After core operations work:

  • Add remaining S0 commands (font, paragraph, geometry)
  • Add diagnostic commands (validate, doctor, inspect)
  • Add S1 commands (fill, line, z-order)
  • Add S2 commands with confirmation

4. Documentation

  • Add API usage examples to README
  • Create command reference documentation
  • Add troubleshooting guide

Questions for User

  1. PPTX Library Documentation: Do you have API documentation for @deckflow/presentation and @deckflow/pptx-modifier? This is needed to implement the reader/writer classes.

  2. Priority Commands: Which commands should be implemented first after the core PPTX integration?

  3. Testing: Do you have sample PPTX files we can use for testing?

Summary

The DeckUse project infrastructure is complete and working. The architecture is solid, type-safe, and ready for PPTX library integration. Once the PPTX reading/writing libraries are integrated, the project will be fully functional for the Phase 1 scope (core workflow + basic read/write commands).

All code is:

  • ✅ Type-safe (strict TypeScript)
  • ✅ Well-structured and modular
  • ✅ Tested (where possible without PPTX libs)
  • ✅ Documented with inline comments
  • ✅ Ready for PPTX integration
