Post-Commit Web Hooks for Google Code Project Hosting

Thursday, January 29, 2009

By Mike Parent, Google CodeWe love to create building blocks that fuel user's imaginations. Today we are announcing Post-Commit Web Hooks for Project Hosting on Google Code, to allow web services to receive repository commit notifications. Projects can use this feature to integrate with all kinds of external tools, including continuous build systems, bug trackers, project metrics, and social networks. The notification follows the Web Hooks model, and is delivered as an HTTP POST request containing a JSON commit description.

To help get you started, we've created an example application that performs various tests that are useful for managing documentation. You can find the source code in the contenthooks open source project.

We would love to hear feedback about new and interesting uses of Post-Commit Web Hooks!

Google Visualization API interactive samples in the AJAX APIs Playground

Monday, January 26, 2009

By Nir Bar-Lev, Google Developer Programs

We all know that writing code based on existing code snippets is faster and quicker than starting from scratch. It's also a great way to ramp up on new tools or APIs you may be less familiar with.

That's way we decided to provide a whole bunch of interactive code samples for the Google Visualization API in Google's recently launched AJAX APIs Playground.

These code samples run the gamut from specific visualizations like for the Motion Chart, Annotated Time Line (used in Google Finance) or Geo Map to covering specific Visualization API topics like event handling and placing data source requests.

The Playground enables you to change the sample code, re-run it, and see the results in real time. You can export your code, save it, and also get a full HTML source. In fact, for most of your programming needs, this tool is all you'll ever need to write, debug and integrate visualizations from the Visualization API into your web pages.

We hope you enjoy the added productivity and wish you happy visualizing!

Playing around with Google's AJAX APIs

Wednesday, January 21, 2009

By Ben Lisbakken, Developer Programs EngineerFor me, documentation isn't always enough to learn about APIs; I need examples that I can play with. That's why I started a fun project recently--a tool for teaching developers how to use Google's JavaScript APIs: the AJAX API Playground. I have been working on this in my 20% time and today I am proud to announce that we are launching the AJAX API Playground as the official way that Google will show JavaScript samples!

The AJAX API Playground is currently loaded with over 170 samples for 8 Google JavaScript APIs (Maps, Search, Feeds, Calendar, Visualization, Language, Blogger, Libraries and Earth) that you can edit and run to help you explore what Google's APIs have to offer. There are also save and export features. The save feature allows you to hold onto an edited sample so you can continue working on it later, while export lets you modify a sample and publish the code to a permanent url.

As the AJAX API Playground is built on App Engine, you can create your own App Engine instance to show off your code samples. The code is open sourced under an Apache 2.0 license and uses several open source libraries and tools, including jQuery, jQuery UI, YUI Compressor, and CodeMirror. You can find the code on Google Project Hosting and learn about adding samples on the project wiki.

Stay tuned for more samples for more APIs. Enjoy!
