Marp Extended

Marp Extended is an Obsidian plugin for creating, previewing, presenting, and exporting Marp slide decks from Markdown notes.

Project lineage: Marp Extended originated from Samuele Cozzi's Marp Slides for Obsidian and is now maintained as an independent plugin project. Upstream credits are preserved below.

Features

• Preview Marp slides inside Obsidian.
• Export slide decks as HTML, PDF, or PPTX through a user-installed Marp CLI.
• Present slide decks from the plugin.
• Use bundled Marp theme CSS installed into .marp-extended/themes/ on first load, plus custom theme CSS from your vault.
• Add custom Marp themes by pasting CSS in plugin settings.
• Convert Obsidian image wiki-links to standard Markdown image links for preview/export.
• Built-in Mermaid diagrams rendered with beautiful-mermaid and official Mermaid, featuring an interactive zooming and panning frame in the editor Live Preview (can be toggled in settings).
• Kami DSL fenced blocks for Obsidian-friendly slide metadata, lead text, callouts, columns, and 2×2 cards.

Markdown compatibility

Marp Extended renders slides with Marp, so notes should primarily use Marp-compatible Markdown. Obsidian image embeds are supported as a convenience by converting image wiki-links before preview/export.

Supported image wiki-link forms:

For example:

![[Pasted image 20260625124927.png]]
![[Pasted image 20260625124927.png|Screenshot]]
![[Pasted image 20260625124927.png|600]]
![[Pasted image 20260625124927.png|600x400]]

These are converted to standard Markdown image links / Marp image directives. Paths are URL-encoded so spaces become %20:

![Pasted image 20260625124927.png](Pasted%20image%2020260625124927.png)
![Screenshot](Pasted%20image%2020260625124927.png)
![w:600](Pasted%20image%2020260625124927.png)
![w:600 h:400](Pasted%20image%2020260625124927.png)

When possible, the plugin resolves the image through Obsidian's link resolver and emits a path Marp can read. If the image cannot be resolved, the plugin falls back to treating the wiki-link target as a path relative to the current note.

Other Obsidian-only extensions are not converted automatically. If Marp does not support an Obsidian syntax directly, write it in standard Markdown or Marp syntax.

For Kami-style decks, Marp Extended also supports a small fenced-block DSL that compiles to Marp local directives and Kami theme HTML wrappers before preview/export. For example, use slide blocks instead of Marp local directive comments and cols / cards[2x2] blocks split with === for common Kami layouts. Previewing these layout wrappers requires the plugin's Enable HTML setting; export already invokes Marp CLI with HTML enabled. See Kami DSL for the supported blocks and examples.

Getting started

Install from Obsidian Community plugins

Marp Extended is submitted to the Obsidian community plugin directory:

https://community.obsidian.md/plugins/marp-extended

Open the plugin page in Obsidian or search for Marp Extended in Settings → Community plugins → Browse.

Install with BRAT

Marp Extended can also be installed from this repository with BRAT:

1. Install and enable the BRAT plugin in Obsidian.
2. Open BRAT settings and choose Add Beta plugin.
3. Paste this repository URL: https://github.com/shuuul/obsidian-marp-extended.
4. Enable Marp Extended in Obsidian community plugin settings.

First use

1. Install from the Obsidian community plugin directory, install with BRAT, or build the plugin into your vault's .obsidian/plugins/marp-extended/ directory.
2. Enable Marp Extended in Obsidian community plugin settings.
3. On first load, Marp Extended installs bundled, managed default theme CSS into .marp-extended/themes/. Fork a bundled theme in settings before editing it.
4. Open a Markdown note and run Slide Preview from the command palette or ribbon icon.
5. To export, install or configure Marp CLI (or enable npx fallback) and then use the export commands for PDF, PDF with notes, HTML, or PPTX.

Local fonts for bundled themes

Bundled themes do not load font files from the network. Install the matching fonts on your operating system before opening Obsidian when you want the theme to match its upstream design; otherwise the browser uses the CSS fallback stack.

Marp Extended does not bundle these font files. TsangerJinKai02 may require a separate license for commercial use.

Export requirements

Preview and presentation work from the plugin bundle. Export runs an external Marp CLI command so Marp Extended does not bundle the full CLI/Puppeteer toolchain.

Install Marp CLI globally, set an explicit executable path in Settings → Marp Extended → Marp CLI path, or enable Use npx fallback to let the plugin run a pinned Marp CLI package through npx when no executable is found or when a browser-backed PDF/PPTX export fails without an explicit CLI path:

npm install -g @marp-team/marp-cli
marp --version

Use Auto-detect in settings to search PATH and common Homebrew locations such as /opt/homebrew/bin/marp. If marp is not found automatically, set Marp CLI path to the executable path, such as /opt/homebrew/bin/marp or C:\Users\you\AppData\Roaming\npm\marp.cmd.

The opt-in npx fallback uses @marp-team/[email protected]. It requires Node.js/npm and may download the package on first use.

⚠️ PDF and PPTX export require Google Chrome, Chromium, or Microsoft Edge. You can set a custom browser path with the CHROME_PATH setting if Marp CLI cannot auto-detect your browser.

Development

npm install
npm run typecheck
npm run lint
npm test -- --runInBand
npm run build

For live Obsidian testing, copy .env.local.example to .env.local and set OBSIDIAN_VAULT to your vault path. npm run dev and npm run build will then auto-copy main.js, manifest.json, and styles.css into <vault>/.obsidian/plugins/marp-extended/. Reload the dev plugin with the Obsidian CLI:

npm run obsidian:reload

Useful scripts:

main.js is generated. Edit files under src/, then rebuild.

Developer guidance lives in AGENTS.md. Release notes live in CHANGELOG.md.

Current Marp-related runtime dependencies are @marp-team/marp-core ^4.3.0 and beautiful-mermaid ^1.1.3. Export uses an external @marp-team/marp-cli executable or optional npx fallback instead of bundling Marp CLI into main.js.

Security note

Runtime and development dependencies audit clean with npm audit and npm audit --omit=dev.

Acknowledgment

Marp Extended builds on the original Marp Slides for Obsidian plugin by Samuele Cozzi.

Bundled default themes are limited to kami, kami-en, github, beamer, olive, and dracula, with CSS from tw93/Kami, matsubara0507/marp-themes, dracula/marp, plus the Marp Extended Beamer sample theme. These upstream projects are MIT-licensed; keep their notices when redistributing modified theme CSS. Kami's Chinese theme references TsangerJinKai02 fonts, whose commercial usage may require a separate font license.
