    reveal-md

    5.3.4 • Public • Published

    reveal-md

    reveal.js on steroids! Get beautiful reveal.js presentations from Markdown files.

    Installation

    npm install -g reveal-md

    Usage

    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:

    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.

    To enable live reload in the container, port 35729 should be mapped as well:

    docker run --rm -p 1948:1948 -p 35729:35729 -v <path-to-your-slides>:/slides webpronl/reveal-md:latest /slides --watch

    Features

    Markdown

    The Markdown feature of reveal.js is awesome, and has an easy (and configurable) syntax to separate slides. Use three dashes surrounded by two blank lines (\n---\n). Example:

    # Title
    
    - Point 1
    - Point 2
    
    ---
    
    ## Second slide
    
    > Best quote ever.
    
    Note: speaker notes FTW!

    Theme

    Override theme (default: black):

    reveal-md slides.md --theme solarized

    See available themes.

    Override reveal theme with a custom one. In this example, the file is at ./theme/my-custom.css:

    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):

    reveal-md slides.md --theme https://rawgit.com/puzzle/pitc-revealjs-theme/master/theme/puzzle.css

    Highlight Theme

    Override highlight theme (default: zenburn):

    reveal-md slides.md --highlight-theme github

    See available themes.

    Custom Slide Separators

    Override slide separator (default: \n---\n):

    reveal-md slides.md --separator "^\n\n\n"

    Override vertical/nested slide separator (default: \n----\n):

    reveal-md slides.md --vertical-separator "^\n\n"

    Custom Slide Attributes

    Use the reveal.js slide attributes 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:

    # slide1
    
    This slide has no background image.
    
    ---
    
    <!-- .slide: data-background="./image1.png" -->
    
    # 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:

    {
      "separator": "^\n\n\n",
      "verticalSeparator": "^\n\n"
    }

    Reveal.js Options

    Define Reveal.js options in a reveal.json file that must be located at the root directory of the Markdown files. They'll be picked up automatically. Example:

    {
      "controls": true,
      "progress": true
    }

    Speaker Notes

    Use the speaker notes 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:

    ---
    title: Foobar
    separator: <!--s-->
    verticalSeparator: <!--v-->
    theme: solarized
    revealOptions:
      transition: 'fade'
    ---
    
    Foo
    
    Note: test note
    
    <!--s-->
    
    # Bar
    
    <!--v-->

    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.

    reveal-md slides.md -w

    Custom Scripts

    Inject custom scripts into the page:

    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:

    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.

    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:

    // 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

    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:

    reveal-md slides.md --print slides.pdf

    The PDF is generated using Puppeteer. Alternatively, append ?print-pdf 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 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:

    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 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:

    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 ?print-pdf 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, 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):

    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.

    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):

    reveal-md dir/ --static

    By default, all *.md files in all subdirectories are included in the generated website. Provide a custom glob pattern using --glob to generate slides only from matching files:

    reveal-md dir/ --static --glob '**/slides.md'

    Additional --absolute-url and --featured-slide parameters could be used to generate OpenGraph metadata enabling more attractive rendering for slide deck links when shared in some social sites.

    reveal-md slides.md --static _site --absolute-url https://example.com --featured-slide 5

    Disable Auto-open Browser

    To disable auto-opening the browser:

    reveal-md slides.md --disable-auto-open

    Directory Listing

    Show (recursive) directory listing of Markdown files:

    reveal-md dir/

    Show directory listing of Markdown files in current directory:

    reveal-md

    Custom Port

    Override port (default: 1948):

    reveal-md slides.md --port 8888

    Custom Template

    Override reveal.js HTML template (default template):

    reveal-md slides.md --template my-reveal-template.html

    Override listing HTML template (default template):

    reveal-md slides.md --listing-template my-listing-template.html
