A minimal publishing system based on Pandoc, Substance and eLife Lens. It powers

Substance IO

A minimal publishing solution based on Pandoc Markdown and Substance.

  • Node.js >=0.10.x
  • Pandoc >= 1.12.02 (for Markdown cross-compiling)

Substance.IO comes as a ready-to-use NPM module:

$ sudo npm install -g substance-io

To view a document library (such as Substance Documents) call:

$ cd /path/to/library
$ io

Or alternatively you can point to that folder using:

$ io <path-to-library-folder>

Documents are managed by convention in a directory structure having folders for collections and subfolders for documents. For example:

mylibrary/substance                    # collection folder
mylibrary/substance/index.json         # collection metadata
mylibrary/substance/about              # document folder
mylibrary/substance/about/index.json   # document metadata
mylibrary/substance/about/   # source markdown

This would define a library with one collection with id substance having one document with id about.

For development we use a setup based on our Screwdriver command line utility. It's just a little helper that makes dealing with our many modules easier.

$ git clone
$ cd screwdriver
$ sudo python install

Clone the io repo.

$ git clone

Run the update command, which pulls in all the sub-modules and dependencies.

$ cd io
$ substance --update

Finally start the server and point your browser to http://localhost:5000.

$ substance <path-to-library-folder>
