    Markpress npm badge Build Status node GitHub stars GitHub followers

    markpress is a command line tool and node package to convert markdown files into self-contained impressjs html presentations. It was initially inspired and based on markdown-impress by steel1990.

    This is the outcome of feeding this very README.md to markpress: $ markpress README.md


    How to install

    You'll need node version >= 5.0.0 installed on your system.

    $ npm install -g markpress (globally)

    or

    $ npm install markpress (for the current folder only)


    Features

    • Automatic slide layout generation
    • Automatic slide split by h1
    • Built-in themes ( dark, light, dark-serif, light-serif). Customizable through <style> tags.
    • Generates self-contained HTML file by embedding images (no network connection needed when presenting)
    • Code highlighting for most common programming languages
    • Supports HTML & Emojis! 😄👍 🐫💨
    • Live editor mode via the --edit option to live-preview your changes
    • Responsive design adapts to different screen sizes
    • Adaptive text size (using vmin and vmax)
    • Github-inspired CSS styles
    • Will run fine in the latest Firefox, Chrome, Safari and probably Edge *

    Usage

    CLI

    $ markpress <input file> [output file] [options]

    If no output file is passed, the input's filename will be used with .html extension.

    More information: $ markpress -h

    In your code

    See Examples section for more.

    const fs = require('fs');
    const markpress = require('markpress');
    const options = { ... };
    markpress('input.md', options).then(({html, md}) => {
      fs.writeFileSync('output.html', html);
    });
     
    // or you can pass the Markdown content directly as parameter
    markpress('# Markdown content \n > Blockquote', options).then(({html, md}) => {
      fs.writeFileSync('output.html', html);
    });

    Markdown format, Custom Layout and Styles

    • Github Flavored Markdown format is supported via marky-markdown package, including tables.
    • Use ------ to separate each slide, or user the -a option to generate a slide each time an h1 element is found.
    • Use HTML comments to set impress slide attributes, such as <!--slide-attr x=0 y=0 rotate=0 scale=1 -->. Example
    • You can customize the styles by embedding CSS in <style> tags as you would in any HTML - be careful as an empty slide will be created when including styles at the top and enabling the -a --auto-split flag.
    • You can embedded any HTML in your markdown file and it will be included in your slides HTML.

    Options

    The options precedence is as follows (higher in the least means higher precedence):

    • Options passed directly through CLI / code.
    • Options embedded in the .md file (see --save option)

    -a, --auto-split or { autoSplit: Boolean } in code

    Default: false

    Automatically create a slide for every H1 (# Heading 1) level element (if ------ are present will be removed and ignored)


    -l, --layout or { layout: String } in code

    Default: horizontal

    Automatically generate the layout for the slides. This option will be ignored if any HTML comment specifying slide positioning attributes is found, so please remove all slide-positioning comments (<!--slide-attr ... -->) from the markdown file if you want to use this feature. Available Layouts:

    • horizontal (default): Slides positioned along the x axis. Example
    • vertical: Slides positioned along the y axis. Example
    • 3d-push: Slides positioned along the z axis. Slide n will be positioned lower than n+1. Example
    • 3d-pull: Slides positioned along the z axis. Slide n will be positioned higher than n+1.
    • grid: Slides positioned along the x and y axis in a grid fashion. Example
    • random: Slides positioned randomly on a 5D space (x,y,z,rotate,scale). Note that this layout generator might position slides on top of each other. Re-generate until a satisfactory layout is generated. Example
    • random-7d: [warning: messy] Slides positioned randomly on the 7D space (x,y,z,rotate-x,rotate-y,rotate-z,scale). This layout generator might position slides on top of each other. Re-generate until a satisfactory layout is generated. Example

    -E, --no-embed or { embed: false } in code

    Default: true (pass --no-embed through CLI to disable)

    By default, markpress will try to embed (using base64 encoding) the referenced images into the HTML so they will be available offline and you will not have problems moving the HTML to other folders. This feature will be disabled if --no-embed is set to true.

    -z, --sanitize or { sanitize: boolean } in code

    Default: false (dangerous HTML & scripts allowed)

    Disallow embedding of dangerous HTML code in the Markdown file. You should leave it disabled if you want to use custom <style> tags, embed videos, etc.

    --silent or { verbose: Boolean } in code

    --silent Will silence all console output in the Terminal. {verbose: true} will enable all console output.

    Default (CLI): silence: false (all console output enabled by default)

    Default (module): verbose: false (all console output disabled by default)


    -t <theme>, --theme <theme> or { theme: String } in code

    Default: light

    Chose from the different available themes:

    • light (default): Light theme with Sans-serif font
    • dark: Dark theme with Sans-serif font. Example
    • light-serif: Light theme with Sans-Serif font. Example
    • dark-serif: Light theme with Serif font

    -s, --save or { save: Boolean } in code

    Default: false

    Embed the markpress options into the .md file for portability. Warning: it will override any existing options.

    -e, --edit only available in CLI

    Start edit mode. This will start an embedded web server to preview the resulting HTML with live refresh upon input file change. Press ctrl+c to stop the server.


    Developing

    Run

    $ node --harmony ./bin/markpress.js input.md

    Debug

    $ node debug --harmony ./bin/markpress.js input.md

    Linking

    npm link

    Installing local version globally

    npm install . -g


    API

    markpress(input, options)

    input

    An String with either:

    • The path relative to the execution directory to the input Markdown file. e.g. ../input.md, /abs/path/input.md
    • A Markdown-formatted String

    options

    An Object containing the options as specified in the Options section

    returns

    A Promise which will call it's resolve method with an Object with two properties:

    • html: The html String produced from the Markdown input.
    • md: [Optional] - If this parameter is defined, it contains the Markdown input updated with the embedded options (see --save option).

    Note that you can use ES6 destructuring to simulate Python's named parameters in JS.


    Examples

    const fs = require('fs');
    const markpress = require('markpress');
    const options = {
      layout: 'horizontal',
      theme: 'light',
      autoSplit: true,
      allowHtml: false,
      verbose: false,
      title: 'Optional <title> for output HTML'
    }
    // Simulating named parameters through destructuring
    markpress('input.md', options).then(({html, md}) => {
      fs.writeFileSync('output.html', html);
      // if `md` is defined it contains the markdown content with embedded options (see --save option)
    });
     
    // or you can pass the Markdown content directly as parameter
     
    markpress(
      '# This is markdown content \n > Test Blockquote',
      options
    ).then(({html, md}) => {
      fs.writeFileSync('output.html', html);
    });
