# reveal-md [reveal.js][1] on steroids! Get beautiful reveal.js presentations from Markdown files. > [!NOTE] > > reveal-md is no longer in active development. No new features will be added. Pull requests for bug and documentation fixes will be considered. Occasional dependency upgrades and CVEs might happen. Thanks for using reveal-md! Please consider alternatives to Markdown-based solutions: - [MkSlides](https://martenbe.github.io/mkslides/) - [Slidev](https://sli.dev) ## Installation ```console npm install -g reveal-md ``` ## Usage ```console reveal-md slides.md ``` This starts a local server and opens any Markdown file as a reveal.js presentation in the default browser. ## Docker You can use Docker to run this tool without needing Node.js installed on your machine. Run the public Docker image, providing your markdown slides as a volume. A few examples: ```console docker run --rm -p 1948:1948 -v <path-to-your-slides>:/slides webpronl/reveal-md:latest docker run --rm -p 1948:1948 -v <path-to-your-slides>:/slides webpronl/reveal-md:latest --help ``` The service is now running at [http://localhost:1948][2]. To enable live reload in the container, port 35729 should be mapped as well: ```console docker run --rm -p 1948:1948 -p 35729:35729 -v <path-to-your-slides>:/slides webpronl/reveal-md:latest /slides --watch ``` ## Features - [Installation][3] - [Usage][4] - [Docker][6] - [Features][7] - [Markdown][8] - [Code Section][59] - [Theme][9] - [Highlight Theme][10] - [Custom Slide Separators][11] - [Custom Slide Attributes][12] - [reveal-md Options][13] - [Reveal.js Options][14] - [Speaker Notes][15] - [YAML Front matter][16] - [Live Reload][17] - [Custom Scripts][18] - [Custom CSS][19] - [Custom Favicon][20] - [Pre-process Markdown][21] - [Print to PDF][22] - [1.

Use three dashes surrounded by two blank lines (`\n---\n`). Example: ```markdown # Title - Point 1 - Point 2 --- ## Second slide > Best quote ever. Note: speaker notes FTW! ``` #### Code section ##### Syntax highlighting ````markdown ```js console.log('Hello world!'); ``` ```` ##### Highlight some lines You can highlight one line, multiple lines or both. ````markdown ```python [1|3-6] n = 0 while n < 10: if n % 2 == 0: print(f"{n} is even") else: print(f"{n} is odd") n += 1 ``` ```` ### Theme Override theme (default: `black`): ```console reveal-md slides.md --theme solarized ``` See [available themes][34]. Override reveal theme with a custom one. In this example, the file is at `./theme/my-custom.css`: ```console reveal-md slides.md --theme theme/my-custom.css ``` Override reveal theme with a remote one (use rawgit.com because the url must allow cross-site access): ```console reveal-md slides.md --theme https://rawgit.com/puzzle/pitc-revealjs-theme/master/theme/puzzle.css ``` ### Highlight Theme Override highlight theme (default: `zenburn`): ```console reveal-md slides.md --highlight-theme github ``` See [available themes][35]. ### Custom Slide Separators Override slide separator (default: `\n---\n`): ```console reveal-md slides.md --separator "^\n\n\n" ``` Override vertical/nested slide separator (default: `\n----\n`): ```console reveal-md slides.md --vertical-separator "^\n\n" ``` ### Custom Slide Attributes Use the [reveal.js slide attributes][36] functionality to add HTML attributes, e.g. custom backgrounds. Alternatively, add an HTML `id` attribute to a specific slide and style it with CSS. Example: set the second slide to have a PNG image as background: ```markdown # slide1 This slide has no background image. ---  # slide2 This one does! ``` ### reveal-md Options Define options similar to command-line options in a `reveal-md.json` file that must be located at the root of the Markdown files. They'll be picked up automatically. Example: ```json { "separator": "^\n\n\n", "verticalSeparator": "^\n\n" } ``` ### Reveal.js Options Define Reveal.js [options][37] in a `reveal.json` file at the project root. They'll be picked up automatically. Example: ```json { "controls": true, "progress": true } ``` ### Speaker Notes Use the [speaker notes][38] feature by using a line starting with `Note:`. ### YAML Front matter Set Markdown (and reveal.js) options specific to a presentation with YAML front matter: ```markdown --- title: Foobar separator:  verticalSeparator:  theme: solarized revealOptions: transition: 'fade' --- Foo Note: test note  # Bar  ``` ### Live Reload Using `-w` option changes to markdown files will trigger the browser to reload and thus display the changed presentation without the user having to reload the browser. ```console reveal-md slides.md -w ``` ### Custom Scripts Inject custom scripts into the page: ```console reveal-md slides.md --scripts script.js,another-script.js ``` - Don't use absolute file paths, files should be in adjacent or descending folders. - Absolute URL's are allowed. ### Custom CSS Inject custom CSS into the page: ```console reveal-md slides.md --css style.css,another-style.css ``` - Don't use absolute file paths, files should be in adjacent or descending folders. - Absolute URL's are allowed. ### Custom Favicon If the directory with the markdown files contains a `favicon.ico` file, it will automatically be used as a favicon instead of the [default favicon][39]. ### Pre-process Markdown `reveal-md` can be given a markdown preprocessor script via the `--preprocessor` (or `-P`) option. This can be useful to implement custom tweaks on the document format without having to dive into the guts of the Markdown parser. For example, to have headers automatically create new slides, one could have the script `preproc.js`: ```javascript // headings trigger a new slide // headings with a caret (e.g., '##^ foo`) trigger a new vertical slide module.exports = (markdown, options) => { return new Promise((resolve, reject) => { return resolve( markdown .split('\n') .map((line, index) => { if (!/^#/.test(line) || index === 0) return line; const is_vertical = /#\^/.test(line); return (is_vertical ? '\n----\n\n' : '\n---\n\n') + line.replace('#^', '#'); }) .join('\n') ); }); }; ``` and use it like this ```console reveal-md --preprocessor ./preproc.js slides.md ``` ### Print to PDF There are (at least) two options to export a deck to a PDF file. #### 1. Using Puppeteer Create a (printable) PDF from the provided Markdown file: ```console reveal-md slides.md --print slides.pdf ``` The PDF is generated using Puppeteer. Alternatively, append `?view=print` to the url from the command-line or in the browser (make sure to remove the `#/` or `#/1` hash). Then print the slides using the browser's (not the native) print dialog. This seems to work in Chrome. By default, paper size is set to match options in your [`reveal.json`][14] file, falling back to a default value 960x700 pixels. To override this behaviour, you can pass custom dimensions or format in a command line option `--print-size`: ```console reveal-md slides.md --print slides.pdf --print-size 1024x768 # in pixels when no unit is given reveal-md slides.md --print slides.pdf --print-size 210x297mm # valid units are: px, in, cm, mm reveal-md slides.md --print slides.pdf --print-size A4 # valid formats are: A0-6, Letter, Legal, Tabloid, Ledger ``` In case of an error, please try the following: - Analyze debug output, e.g. `DEBUG=reveal-md reveal-md slides.md --print` - See `reveal-md help` for Puppeteer arguments (`puppeteer-launch-args` and `puppeteer-chromium-executable`) - Use Docker & DeckTape: #### 2. Using Docker & DeckTape The first method of printing does not currently work when running reveal-md in a Docker container, so it is recommended that you print with [DeckTape][40] instead. Using DeckTape may also resolve issues with the built-in printing method’s output. To create a PDF of a presentation using reveal-md running on your localhost using the DeckTape Docker image, use the following command: ```console docker run --rm -t --net=host -v $OUTPUT_DIR:/slides astefanutti/decktape $URL $OUTPUT_FILENAME ``` Replace these variables: - `$OUTPUT_DIR` is the folder you want the PDF to be saved to. - `$OUTPUT_FILENAME` is the name of the PDF. - `$URL` is where the presentation can be accessed in your browser (without the `?view=print` suffix). If you are not running reveal-md in Docker, you will need to replace `localhost` with the IP address of your computer. For a full list of export options, please see the the [DeckTape github][40], or run the Docker container with the `-h` flag. ### Static Website This will export the provided Markdown file into a stand-alone HTML website including scripts and stylesheets. The files are saved to the directory passed to the `--static` parameter (default: `./_static`): ```console reveal-md slides.md --static _site ``` This should copy images along with the slides. Use `--static-dirs` to copy directories with other static assets to the target directory. Use a comma-separated list to copy multiple directories. ```console reveal-md slides.md --static --static-dirs=assets ``` Providing a directory will result in a stand-alone overview page with links to the presentations (similar to a [directory listing][27]): ```console reveal-md dir/ --static ``` By default, all `*.md` files in all subdirectories are included in the generated website. Provide a custom [glob pattern][41] using `--glob` to generate slides only from matching files: ```console reveal-md dir/ --static --glob '**/slides.md' ``` Additional `--absolute-url` and `--featured-slide` parameters could be used to generate [OpenGraph][42] metadata enabling more attractive rendering for slide deck links when shared in some social sites. ```console reveal-md slides.md --static _site --absolute-url https://example.com --featured-slide 5 ``` ### Disable Auto-open Browser To disable auto-opening the browser: ```console reveal-md slides.md --disable-auto-open ``` ### Directory Listing Show (recursive) directory listing of Markdown files: ```console reveal-md dir/ ``` Show directory listing of Markdown files in current directory: ```console reveal-md ``` ### Custom Port Override port (default: `1948`): ```console reveal-md slides.md --port 8888 ``` ### Custom Template Override reveal.js HTML template ([default template][43]): ```console reveal-md slides.md --template my-reveal-template.html ``` Override listing HTML template ([default template][44]): ```console reveal-md slides.md --listing-template my-listing-template.html ``` ## Scripts, Preprocessors and Plugins - [reveal-md-scripts][45] - [How to add reveal.js plugins][58] ## Related Projects & Alternatives - [Slides][46] is a place for creating, presenting and sharing slide decks. - [Sandstorm Hacker Slides][47] is a simple app that combines Ace Editor and RevealJS. - [Tools][48] in the Plugins, Tools and Hardware section of Reveal.js. - [Org-Reveal][49] exports Org-mode contents to Reveal.js HTML presentation. - [DeckTape][40] is a high-quality PDF exporter for HTML5 presentation frameworks. - [GitPitch][50] generates slideshows from PITCHME.md found in hosted Git repos. ## Articles About reveal-md - [great slides with reveal markdown][51] - [Create your own auto-publishing slides with reveal-md and Travis CI][52] - [Beautiful presentations from markdown — who knew it could be so easy?][53] - [Using reveal-md to create technical presentations][54] - [Use reveal-md to generate multiple slides and host them on GitHub Page][55] ## Thank You Many thanks to all [contributors][56]! ## License [MIT][57] [1]: https://revealjs.com [2]: http://localhost:1948 [3]: #installation [4]: #usage [5]: #revealjs-v4 [6]: #docker [7]: #features [8]: #markdown [9]: #theme [10]: #highlight-theme [11]: #custom-slide-separators [12]: #custom-slide-attributes [13]: #reveal-md-options [14]: #revealjs-options [15]: #speaker-notes [16]: #yaml-front-matter [17]: #live-reload [18]: #custom-scripts [19]: #custom-css [20]: #custom-favicon [21]: #pre-process-markdown [22]: #print-to-pdf [23]: #1-using-puppeteer [24]: #2-using-docker--decktape [25]: #static-website [26]: #disable-auto-open-browser [27]: #directory-listing [28]: #custom-port [29]: #custom-template [30]: #scripts-preprocessors-and-plugins [31]: #related-projects--alternatives [32]: #thank-you [33]: #license [34]: https://github.com/hakimel/reveal.js/tree/master/css/theme/source [35]: https://github.com/isagalaev/highlight.js/tree/master/src/styles [36]: https://revealjs.com/markdown/#slide-attributes [37]: https://revealjs.com/config/ [38]: https://revealjs.com/speaker-view/ [39]: lib/favicon.ico [40]: https://github.com/astefanutti/decktape [41]: https://github.com/isaacs/node-glob [42]: http://ogp.me [43]: https://github.com/webpro/reveal-md/blob/master/lib/template/reveal.html [44]: https://github.com/webpro/reveal-md/blob/master/lib/template/listing.html [45]: https://github.com/amra/reveal-md-scripts [46]: https://slides.com/ [47]: https://github.com/jacksingleton/hacker-slides [48]: https://github.com/hakimel/reveal.js/wiki/Plugins,-Tools-and-Hardware#tools [49]: https://github.com/yjwen/org-reveal [50]: https://github.com/gitpitch/gitpitch [51]: https://csinva.io/blog/misc/19_reveal_md_enhanced/readme.html [52]: https://ericmjl.github.io/blog/2020/1/18/create-your-own-auto-publishing-slides-with-reveal-md-and-travis-ci/ [53]: https://mandieq.medium.com/beautiful-presentations-from-markdown-who-knew-it-could-be-so-easy-d279aa7f787a [54]: https://lacourt.dev/2019/03/12 [55]: https://hanklu.tw/blog/use-reveal-md-to-generate-multiple-slides-and-host-them-on-github-page/ [56]: https://github.com/webpro/reveal-md/graphs/contributors [57]: http://webpro.mit-license.org [58]: https://github.com/webpro/reveal-md/issues/102#issuecomment-692494366 [59]: #code-section
