OciDeck

A desktop application for building Marp presentations through a structured, slide-by-slide editor — no raw Markdown wrangling required. Compose decks from typed slide templates (title, bullets, quotes, tables, images, video, audio), preview them live, present them fullscreen, and export to Marp Markdown, PDF, and PPTX.

Built with Flutter for macOS, Windows, and Linux.

Features

Structured slide editors — dedicated editors per slide type: title, bullets, two-column bullets, bullets + image, single/two images, quote, table, section divider, image-only, video, audio, and free-form Markdown.
Live preview — see each slide rendered as you edit, with inline Markdown, footers, and TLP (Traffic Light Protocol) marking.
Fullscreen presenter — keyboard-driven navigation, presenter view, and a slide-grid overview.
Media handling — drag-and-drop images, an image carousel picker, captions, and descriptions stored as sidecar metadata.
Import / export — round-trips Marp Markdown, imports existing slides, and exports to PDF and PPTX. Decks are saved as a self-contained package with copied assets.
Productivity — find & replace, slide finder, undo/redo, skip-slide state, and tabbed multi-deck editing.
Crash recovery — automatic snapshots so work survives an unexpected exit.
Theming — a bundled Marp CSS theme (assets/themes/ocideck.css) and Google Fonts.

Requirements

Flutter SDK ^3.12.0 (Dart 3.12+)
A desktop target enabled: macOS, Windows, or Linux

Getting started

make setup      # flutter pub get
flutter run -d macos   # or -d windows / -d linux

Development

The Makefile is the entry point for all quality checks. Run make help for the full list.

make check        # format check + static analysis + full test suite (the quality gate)
make check-full   # check + dependency freshness report
make format       # auto-format all Dart code
make analyze      # flutter analyze only
make test         # full test suite only

Targeted test groups speed up focused work:

Target	Covers
`make test-contracts`	Markdown generation/parsing, save-load round-trips, field migration
`make test-preview`	Slide rendering, footers, TLP, inline Markdown, text styles
`make test-export`	PDF/PPTX export and project file-save behavior
`make test-state`	Providers, undo/redo, search/replace, settings, recovery
`make test-services`	Image, caption, and description sidecar services
`make test-presenter`	Fullscreen presenter navigation and keyboard shortcuts

CI runs make check on every push and pull request (see .github/workflows/ci.yml).
