nerdshow

Generate HTML presentations, serve presentation files and control presentation with mobile device.

  • create your presentation by editing Markdown and/or HTML snippets
  • Syntax highlighting (by now only for JavaScript)
  • remote control your presentation with your smartphone
  • share a presentation across many browser instances (on distributed PCs)

The name?

This tool will probably only be used by nerds and the presentations will be for nerds ==> nerdshow!

Demo

Slides

  • http://hgoebl.github.io/nerdshow
  • http://www.goebl.com/slides/

Remote Control

The remote control software only works when pages are served by node.js. In this demo you can see only the mobile application. It is not connected with a presentation.

Generate Presentations

  • Copy examples/empty to local folder
  • Edit presentation.json
  • add Markdown and/or html files and add them to presentation.json (slides array)
  • Markdown extension: insert raw html by placing '.' in the first column, e.g. .</div><div class="slide">
  • Since v0.4.0: <div class="slide"> are generated automatically by runtime (from <h1> until next <h1>)
  • Run generator nerdshow-generate presentation.json
  • Run presentation nerdshow . --debug
  • Open an html5 browser http://localhost:8008/
  • Open remote control http://localhost:8008/nerdshow/rc/

Usage

Run Generator

Usage: nerdshow-generate <path/to/presentation.json> [options]

Options:
  --nerdshow-folder   base url for nerdshow runtime      [default: "/nerdshow"]
  --socketio-enabled  disable socket-io for static html  [default: true]
  --hijs-enabled      highlight code as javascript       [default: true]
  --zoom-enabled      enable zoom.js (Ctrl+Click)        [default: false]
  --help, -h          show help and exit

To disable an option, enter --no-<option>, e.g. --no-socketio-enabled.

If you want to host a presentation on a web-server, you can save space when you reference the nerdshow runtime-files:

  • Either hard-wired in you presentation.json file: "nerdshow-folder": "http://hgoebl.github.io/nerdshow/rt/0.4.0"
  • or as a command-line option: --nerdshow-folder http://hgoebl.github.io/nerdshow/rt/0.4.0

Be aware that github.io will not serve files over https so if your presentation is served via https, this won't work.

Run Presentation

Usage: nerdshow path/to/presentation [options]

Options:
  --port          TCP port of web server        [default: "8008"]
  --encoding, -e  character-set of stdin input  [default: "utf8"]
  --debug         output for easier debugging   [default: false]
  --help, -h      show help and exit

If you run 'nerdshow' w/out a path to a presentation folder, it will serve the examples folder: http://localhost:8008/

Installation

You can install nerdshow locally or globally. This depends on how much your presentations are spread across your file system. If you put them in one location, I would install it locally, if not, then globally (add option -g):

npm install nerdshow [-g]

  • Provide a boilerplate/template for new presentation (nerdshow-create)

  • HowTo documentation + enhance example
  • Implement/Test incremental page updates (ul/li elements coming item by item)
  • Isolate different presentations delivered by the same server
  • Generate a QR-Code for the remote control URL
  • Output error message when used with IE <= 9
  • Write some test code
  • Generate impress.js Slides (Positioning slides along paths/patterns)
