Bringing more context to Gmail contextual gadgets

As part of the launch of Gmail contextual gadgets, Google released a set of predefined extractors that developers could use. These extractors allow developers to match content within a single part of an email message, such as the subject, and use that content to display relevant information to the current user.

Many Gmail contextual gadget developers have expressed a desire to match on more complex patterns than is possible with the predefined extractors. Today, with the launch of the Google Apps extensions console, these complex patterns, known as custom extractors, are now available to drive contextual gadgets.

Custom extractors allow developers to trigger their gadget when a series of conditions are met. For example, a developer could write an extractor that triggered a gadget only when “Hello world” appeared in the subject and “john@example.com” was the sender of the email. This allows developers to more finely tune their gadgets, and provide even more relevant contextual information.

If you’re interested in writing a custom extractor you can get started by reading our documentation. If you have questions, please post them in the forum.

Google acquires Labpixies

Not everyone likes to start their day with just a search box and logo (no matter how cool it is!). Many users want email, videos, news, weather, games, and other information to be at their fingertips each time they open up a browser window. We launched iGoogle in 2005 to address this need by providing a truly personalized homepage with access to any RSS feed and well over a hundred thousand gadgets.

One of the first developers to create gadgets for iGoogle was Labpixies. Over the years, we worked closely together on a variety of projects, including the launch of a number of global OpenSocial based gadgets. Recently, we decided that we could do more if we were part of the same team, and as such, we're thrilled to announce the acquisition of Labpixies.

The team will be based in our ever-growing Tel Aviv office and will anchor our iGoogle efforts across Europe, the Middle East, and Africa. We are looking forward to working with Labpixies to develop great web apps and leverage their knowledge and expertise to help developers and improve the ecosystem overall.

In the meantime, have fun trying to beat me at Flood-It!

Hello to orkut Developers!

As we announced in the last update to the former orkut Developer Blog last week, henceforth we’ll be posting all orkut developer updates to this blog.

We think this is also a good opportunity to quickly introduce the newly-launched Developer page to you. We recently added this feature to the orkut sandbox which we hope to be a one-stop solution for developers looking to manage their applications from a single page and view their stats. You can submit your apps directly from here and verify them to complete the submission process. You can also maintain your apps from here and migrate them to a new URL, or delete them entirely from the directory. And if you have applications that have already been approved and included in the directory, expand their details to track the number of installs, uninstalls, renders and other useful stats updated every week.

Here’s what it looks like in action:


Please note that the Developer page requires you to be on the new orkut UI to work.

So keep your apps coming and point your browser to the one page to manage them all: sandbox.orkut.com/Main#Developer. And stay tuned for all orkut updates right here on the Google Code Blog!

Coming soon: Gmail contextual gadgets available for trusted testers

At Campfire One this week we announced that we will soon open Gmail contextual gadgets as a new extension point for developers. These gadgets can smartly draw information from the web and let users perform relevant actions based on the content of an email message, all without leaving the Gmail inbox. For instance, contextual gadgets currently available in Gmail can detect links in emails to show previews of documents, videos, photos, and more, right inside the messages.

For businesses, Gmail contextual gadgets can boost employee productivity by complementing email in a context-specific and actionable way. Appirio, a cloud solution provider, provided a demonstration of the potential of Gmail contextual gadgets and other experimental features
with their new product PS Connect:



Soon we’ll be opening Gmail contextual gadgets as an extension for trusted testing by developers. If you have a good idea for this type of gadget today, please fill out this form. And for those of you who will be attending Google I/O in May, be sure to check out our session on building Gmail contextual gadgets.

Legacy gadget API deprecation

If you're a gadget developer, you've probably used the gadgets.* API, a re-namespaced and improved version of the original legacy, or _IG_*, gadgets API. The gadgets.* API has gained wide acceptance, both on Google and non-Google gadget containers, and is the standard API for gadget development.

However, there remains a number of gadgets using the legacy API, primarily gadgets developed for iGoogle, and the time to upgrade those gadgets is now. As of today, the legacy gadgets API is officially deprecated. For a period of one year, gadgets using the legacy API will continue to be supported, and function. After that, the legacy API will be turned off for the majority of Google containers (such as iGoogle, orkut, Gmail, and Calendar).

For more specifics on how the deprecation affects iGoogle developers, and details on coming resources to help in the API transition, check out this post on the iGoogle developer blog.

iGoogle adds support for OpenSocial

Developers using the OpenSocial API can now reach tens of millions of iGoogle users! As of this week, iGoogle now supports OpenSocial in both the US and Australia, with the plan to roll it out to more users soon. In general, we think "social is better" when it comes to the web - activities such as reading the news, doing a crossword puzzle, sharing a todo list, or watching a video are all better when done with a friend. These are all things that iGoogle users love to do, so making them social on iGoogle was the next logical next step.

If you're interested in getting started writing social gadgets for iGoogle, check out the full announcement on the iGoogle developer blog.

Google Gadgets going cross-platform

By Mike Pinkerton, Software Engineer

For about two years now, people have been writing gadgets for Google Desktop on
Windows and for iGoogle on the web. Today, with the announcement of Google
Gadgets for Mac OS X, Google Desktop users on the Mac can now run the same
Windows and web-based gadgets in Apple's Dashboard with zero (or very few)
changes. Check it out for yourself.

Google Gadgets for the Mac uses WebKit's JavaScript engine inside Dashboard, so
the majority of gadgets just work if they're written properly. The rest can be
fixed by following a few guidelines:

• Use JavaScript, not JScript
• WebKit is case-sensitive, JScript is not, which can lead to problems if you assume can you do things like interchange SetTimeOut() and setTimeout().
• Avoid JScript-only features like collections and ActiveX.
• Avoid IE-specific DOM extensions, just as if you were writing a multi-browser web application.
• Avoid Windows-specific APIs
• You shouldn't assume ActiveX or certain DLLs are available. Neither WebKit nor Mac OS X supports ActiveX, so these gadgets must be rewritten.
• Avoid Windows-only APIs such as Google Talk. These APIs are not (yet) available on Mac OS X.
• Understand how Dashboard is different
• The Dashboard environment is very different from a web page or the Desktop sidebar on Windows in that it comes and goes as the user activates it. Don't rely on your gadget always being visible. Your gadget won't run or update when Dashboard isn't in the foreground.
• Don't rely on access to the file system. The security model for Dashboard doesn't allow arbitrary file access to the hard disk, although your gadget does have access to files in its own archive. Things like file pickers won't work. Note that while restricted file system access is a departure from how gadgets work on Windows, it's consistent with Dashboard's security model and the behavior of other widgets developed for Mac OS X.

For more details, see Writing a Cross-Platform Gadget, part of the Desktop Gadget API documentation.

If you're interested in developing your own gadget, visit the Gadgets API homepage. If you're already a gadget developer, download the beta today to test your gadget and ensure that it works correctly.

Introducing Calendar Gadgets

By Michael Bolin, Google Calendar Team

You've seen them on iGoogle, in IBM WebSphere Portal, and now you can find them in your favorite online calendar -- that's right, now we're supporting Gadgets in Google Calendar! If you're a Scorpio like me, you can add this gadget that lets you check your horoscope from your calendar (don't worry, all the signs of the zodiac are supported). And if astrology isn't your thing, how about games? This Sudoku gadget was created by Alex Komoroske, one of our interns on the Docs & Spreadsheets team. If you add the gadget, you'll see that the daily puzzles get harder throughout the week.

Finally, if you like to keep up on celebrity birthdays, the birthday reminder will show you who you are idolizing that day:



But you don't have to be a Googler to create a Calendar Gadget -- we have put together new documentation to help you get your favorite Gadgets into Calendar. If you are itching to write some code, then you can use GData or ICAL to add some fancy Calendar Gadget events to your calendar. But if you're out of Red Bull and don't have the time for a late-night hacking session, then you may want to try our new "of-the-day" Calendar Gadget wizard, which makes it easy to take an existing Google Gadget and have it show up once a day, every day, just like the Horoscope and Sudoku Gadgets do.

Let us know how your experiences with Calendar Gadgets are going in the Google Calendar GData API developer forum.

The following are links that we mentioned in the podcast:

AppleScripting Google Desktop means that you can tell the Google Desktop application to do things for you via script. Boss around the system from your own applications and scripts.

The new Google Earth Outreach program has some tutorials such as showing you how to create KML from a spreadsheet.

The Google Mashup Gallery is a mashup itself, that allows you to add your mashup to the mix. Now, everyone will be able to find your Britney vs. Christina mashup!

Geotagged Picasa JSON/KML Output + Driving Directions = Instant Scenic Tours: If you were following the Google blogs yesterday, you would have heard that Picasa now gives you a sleek drag+drop interface for geotagging your photos, and that the Picasa Google data API now outputs the geotagged data using GeoRSS & GML elements. And if you were excited by all that news and immediately visited Picasa to try out the new feature, you might have noticed the big blue KML icon next to a "View in Google Earth" hyperlink. So Picasa now gives developers geotagged photo data both in KML output and the standard Google data API output formats, and that means we map developers have a lot of ways to start playing around with Picasa photos.

New drag-to-route driving directions in google maps - once you have a route, drag the blue line around to have it automatically re-route using your desired roads or intermediate destinations.

Convert Google Gadgets to Other Widget Platforms

Post by Dann Lee, Associate Support Engineer

The Google Gadgets directory contains thousands of gadgets you can use on various google.com sites. In October 2006, we released Google Gadgets For Your Page, allowing you to embed your favorite gadgets in your blogs, websites, and other webpages. Now you can take Google Gadgets and convert them to run in your Windows Vista Sidebar or Mac OS X Dashboard. With the use of third-party utility applications, this is trivial to do.

Mesa Dynamics offers a free widget converter application called Amnesty Generator which converts Google Gadgets to Mac OS X Dashboard Widgets. On February 2nd, they announced a public beta release that's capable of converting Google Gadgets to Windows Vista Sidebar Gadgets as well. This increases distribution of Google Gadgets further and gives gadget authors access to an even wider audience. In addition to Amnesty Generator, Widgetops Universal Google Gadget Widget is a Mac OS X Dashboard Widget that converts Google Gadgets to run on the dashboard.

Viewing Google Gadgets on different sites or platforms does not require any changes. The answer to the question "Why should I write a Google Gadget?" is hopefully becoming more and more clear as rendering platforms become increasingly available, which now includes:

• Google Personalized Homepage
• Google Gadgets For Your Webpage (anywhere on the web)
• Google Page Creator
• Google Desktop
• Windows Vista Sidebar (converter)
• Mac OS X Dashboard (converter, dashboard widget converter)
