# PPTX demos The `pptx/demos` package builds a 26-slide presentation covering text, shapes, charts, tables, media, SmartArt, animations, masters, and typed layouts. It is part of the `moonbitlang/pptx` module and the root Office workspace. Its black-box tests reopen the generated presentations through the public API. `pptx/cmd/demos` is the executable entry point. From the repository root: ```sh moon test --deny-warn --target native pptx/demos bash scripts/generate_pptx_demos.sh bash scripts/validate_pptx.sh demos_out_pptx/sample.pptx ``` The generator decodes the executable's hex output into a PPTX. The default output directory is `demos_out_pptx/`; an explicit directory may be passed to the script. To diagnose one feature, set `split_mode` in [pptx/cmd/demos/main.mbt](../cmd/demos/main.mbt) to `true` and run the executable directly. Its labeled hex streams contain one isolated deck each. Schema checks complement opening, displaying, editing, and reopening the output in PowerPoint, Keynote, or LibreOffice; they do not replace those checks. ## Slide list | # | Slide | Features exercised | |---|---|---| | 1 | Title | Widescreen sizing, styled run, external hyperlink, speaker notes | | 2 | Table of contents | Internal-slide hyperlinks (jump-to-slide via `ppaction://hlinksldjump`) | | 3 | Text features | Multi-paragraph, alignment, AutoNum bullets | | 4 | Shapes | rect / ellipse / round-rect + Connector + GroupShape | | 5 | Custom geometry | Hand-drawn star path | | 6 | Picture | Synthesized 16×16 BMP + image-size auto-detection + crop | | 7 | Tables | Merged header + per-edge custom borders + cell fills | | 8 | Charts I | Bar / line / pie grid | | 9 | Charts II | Area / radar / doughnut grid | | 10 | Charts III | Scatter + bubble (two value-axis families) | | 11 | Charts IV | 3-D bar + stock + of-pie (extended axis + 3-D wrappers) | | 12 | Slide background | Solid-fill slide background | | 13 | Combo chart | Columns + line on a secondary value axis, plus the embedded data workbook — "Edit Data" opens the real rows | | 14 | SVG image | Vector image with a raster fallback | | 15 | Editing shapes | Recolour boxes already on the slide via `map_shapes` | | 16 | Embedded media | A movie + a sound clip (placeholder media payloads) | | 17 | SmartArt | Org chart synthesised into the five-part DiagramML graphic; the whole tree lays out via the recursive layoutDef; the CEO node carries per-node colour overrides | | 18 | Animations | Fly-in entrance + spin emphasis on click (`with_animations` / `Timeline`) | | 19 | Online video | YouTube clip embedded by URL (`add_youtube_video_mut`) | | 20 | Formatting | Shape rotation / flip, run highlight + kerning + outline + glow, shape-level hyperlinks | | 21 | Text fills and spacing | Gradient + pattern **text fills** (`with_text_fill`) and paragraph spacing — 150 % / absolute 28 pt line height, 18 pt space-before (`TextSpacing`) | | 22 | Table styles and fills | A gallery-styled table (`Table::with_style(MediumStyle2Accent1)`) + the `Fill::solid` / `linear_gradient` / `pattern` convenience constructors | | 23 | Master / template | Defined master + footer, auto date, slide number | | 24–25 | Typed layouts | Compile-time placeholder schema (`add_section_header_slide_mut` / `add_title_content_slide_mut`) | | 26 | Closing | Back-link hyperlink + speaker notes | Plus, deck-wide: a slide transition on every slide, named **slide sections** grouping the deck in the slide panel (`set_sections_mut`), and **document properties** in both parts of File ▸ Info — core.xml (title / author / …) and app.xml (company / manager, `set_app_properties_mut`).
