OpenLayers 3

Hosted Examples

The examples are hosted on GitHub (as GitHub pages). See http://openlayers.github.com/ol3/master/examples/.

Build OpenLayers 3

Run build.py:

$ ./build.py

Run examples locally

Run the Plovr web server with:

$ ./build.py serve

Then, either open one of the example html files from the examples directory directly in your browser, or start a simple webserver, for example:

$ python -mSimpleHTTPServer

and explore the examples/ directory, for example by opening http://localhost:8000/examples/side-by-side.html.

You can turn off compilation by appending ?mode=RAW to the URL, for example http://localhost:8000/examples/side-by-side.html?mode=RAW.

Run tests

Run the plovr web server (see above), and either open the test/ol.html file in the browser (e.g. http://localhost:8000/test/ol.html), or run ./build.py test on the console (headless testing with PhantomJS, make sure to install it first from http://phantomjs.org/download.html).

See also the test-specific readme.

Run the linter

First, install the Closure Linter. Then:

$ ./build.py lint

Run the precommit hook before pushing a commit:

$ ./build.py precommit

Add examples

The examples are located in the examples directory. Adding a new example implies creating two files in this directory, a .html file and .js file. See examples/full-screen.html and examples/full-screen.js for instance.

The .html file needs to include a script tag with loader.js?id=<example_name> as its src. For example, if the two files for the examples are myexample.js and myexample.html then id should be set to myexample in the loader.js URL.

build.py serve should be stopped and restarted for the loader.js?id=<example_name> script tag to refer to a valid URL. build.py serve triggers the examples target which creates Plovr JSON file for each example.
