First Time Setup

All command-line operations are scripted using Grunt which is based on Node.js. To get set up:

Install Node, if you haven't already (available at the link above)
Install the Grunt command line runner (if you haven't already); on the command line, run npm install -g grunt-cli
Clone the openseadragon repository
On the command line, go in to the openseadragon folder
Run npm install

You're set... continue reading for build and test instructions.

Building from Source

To build, just run (on the command line, in the openseadragon folder):

grunt

If you want Grunt to watch your source files and rebuild every time you change one, use:

grunt watch

The built files appear in the build folder.

If you want to build tar and zip files for distribution (they will also appear in the build folder), use:

grunt package

Note that the build folder is masked with .gitignore; it's just for your local use, and won't be checked in to the repository.

You can also publish the built version to the site-build repository. This assumes you have cloned it next to this repository. The command is:

grunt publish

... which will delete the existing openseadragon folder, along with the .zip and .tar files, out of the site-build folder and replace them with newly built ones from the source in this repository; you'll then need to commit the changes to site-build.

Testing

Our tests are based on QUnit and PhantomJS; they're both installed when you run npm install. At the moment we don't have much in the way of tests, but we're working to fix that. To run on the command line:

grunt test

If you wish to work interactively with the tests or test your changes:

grunt connect watch

and open http://localhost:8000/ in your browser
