[Google Wave APIs] Office hours this week

[Austin Chau (Google employee)]

Each week, we hold office hours in Wave Sandbox.

This week's office hours will take place at the following time:

San Francisco  (U.S.A. - California) Wednesday, April 7,
2010 at 11:00:00 AM UTC-7 hours
PDT

Sydney  (Australia - New South Wales) Thursday, April 8,
2010 at 4:00:00 AM UTC+10 hours
EST

Corresponding UTC (GMT) Wednesday, April 7, 2010 at 18:00:00

You can use this tool to see what time it is in your timezone:

http://www.timeanddate.com/worldclock/converter.html?year=2010&month=4&day=7&hour=11&min=0&sec=0&p1=224&p2=240

Office hours are also listed on this calendar (which defaults to US Pacific
timezone):

http://code.google.com/events/calendar/

You can add it to your calendar from there, and if your calendar is setup
appropriately, it should show up at your local time. You can also enable a
second timezone in your calendar (MTV + SYD), that helps in converting.

We will create a wave in Wave Preview for office hours, and when it is
starting, we will update this wave, post a link to it in the group and tweet
it from @googlewavedev.

See you then!

Hi Eric,

There was an office hours earlier today.  Unfortunately we forgot to
announce it in the Google Group but we did announce it with ForumBotty on
Wave Preview.  You can read the transcript of the office hours here -

https://wave.google.com/wave/#restored:wave:googlewave.com!w%252BH0P78-uCG

We
will be sure to announce in both places in the future.  Sorry for the
inconvenience.

[Google Wave APIs] Virtual office hour - Wednesday 3pm 17th March 2010 PST

[Austin Chau (Google employee)]

Hi developers -

Wave API virtual office hours for this week will be held at the following
time:

Sydney (Australia - New South Wales) Thursday, 18 March 2010 at 09:00:00 AM
UTC+11 hours EDT

San Francisco (U.S.A. - California) Wednesday, 17 March 2010 at 3:00:00 PM
UTC-8 hours PST

http://www.timeanddate.com/worldclock/converter.html?day=18&month=3&year=2010&hour=9&min=0&sec=0&p1=240&p2=224

We will host the office hours in Wave Preview, since we are now hosting the
Wave forum there, and we would like to keep all communication in one server.
(We still recommend using Wave Sandbox for all your debugging needs, of
course).

We will create a wave in the forum for office hours, and link to it here.

See you guys!

Yes this is actually going to be soon pretty soon with the upcoming new API

Eric Kolotyluk:

We're considering using a wave to tie together one or more different, but
related, applications. One application would create the wave and pass off a
reference to the wave to other applications, and they could all put robots
in the wave to interact with it, and possibily each other - is this a
scenario you guys have envisioned?
Reply

You:

yes that's entirely possible. You can actively create a wave, store it's id
information. And other "agents" can fetch this wave base on these data. We
will be releasing sample app that does things like that along with the
release.

Hi Thomas, talking to people from my office, some say that the whole wave
(navigation+contacts+inbox+wave) have a lot of information, and when they
saw that at first they don't even know where to start to look


and I think the wave itself is a little confused, when there're a lot of
messages (some inside others) most people don't know where to start to read
it. That's why I said to hava a interface mail-like... with only one blip or
wavelet at first

yes, the same layout, but there're a lot of thumbnails that makes it

I think it's little things that can avoid some regular people to try it.

[Google Wave APIs] Virtual office hour - Wednesday 11am 10th Feb 2010 PST

[Austin Chau (Google employee)]

Hi Developers!

A little friendly reminder that we will be hosting virtual office hours for
Wave API in Wave Sandbox on -

Wednesday, 10th Feb 2010 at 11:00:00AM GMT-8 hours PST (San Francisco time).

You can use this tool to see what time it is in your timezone
http://www.timeanddate.com/worldclock/converter.html?year=2010&month=2&day=10&hour=11&min=0&sec=0&p1=224&p2=240

Office hours are also listed on this calendar (which defaults to US
Pacific timezone):
http://code.google.com/events/calendar/

You can add it to your calendar from there, and if your calendar is
setup appropriately, it should show up at your local time.
You can also enable a second timezone in your calendar (MTV + SYD),
that helps in converting.

We will create a public sandbox Wave and post a link to it in this
group when office hours begins.

See you there!

Re: [Google Wave APIs] Managing contact list through gadget api

Hi,

No you cannot manipulate the contact list directly from Wave API, you need
to use the Google Contacts API -

Reply
Edit
11:27 am
You:

That's a good question. I actually haven't tried that out but I can't say
for sure. But I am assuming you are referring to the use of active robot api
that let a robot touches a wave actively. I am thinking that a robot can
only touch the wave if he is explicitly added as a participant even if it is
a public wave. Please post this in the group, I will investigate this and
give you a more confirmed answer on this.

How can a robot see if a blip is public or a private reply with just the
robot in it"?
Reply

you can search for the wavelet that contains the blip to see if there is the
pub...@a.gwave.com participant on it.

and if I've found that, how can I post in the wavelet that is public?
Reply
Edit

You:

That's what I was saying earlier that I am not sure if the robot can reply
to a wavelet even if it is public. I believe robot must be a participant on
wavelet in order for it to touch the wavelet (even if it is public). But I
need to confirm that, so please post this on the group and I will reply to
that later this afternoon.

11:41 am
Tom Maaswinkel:

Well, the point is that I can't find a function that allows me to get to
that other wavelet (since the only wavelet I got access to is given trough
the RobotMessageBundle)
Reply
Edit
11:43 am
You:

Yes that is correct, with the current available client libraries we only
provide interaction between robots and wavelet passively. Meaning exactly
what you have mentioned that robots only know about wavelet when wavelet
triggers an event. But there is a new feature that we will be pushing out
soon that let you do "active" request to a wavelet, given that you know the
wavelet id.
Reply
Edit
11:43 am
Tom Maaswinkel:

The reason that I'm asking is that we want to develop a way to post
'anonymously' in a wave. We are developing the MediawikiWave bot, and one of
the main features of mediawiki is anonymous editing.


Do you maybe know another way to currently do this?
Reply
Edit
11:46 am
You:

I don't have solution off my head because obviously we don't want robot to
be able to do that to any wavelet, major spam/security issue can happen. I
believe the current model only allows a participating robot touch a wavelet.


There is one thing that can do what you mention but that is not part of the
API at the moment. There is something calls Agents but right now they are
only provided internally (Spelly is an example of agents). Agents can touch
any wavelet, sort of a super robots.

[Google Wave APIs] Office Hours starting now!

[Austin Chau (Google employee)]

Please join us for the virtual office hours for Wave API related questions
in Wave sandbox.  This is the public wave -

[Google Wave APIs] Virtual office hour this wednesday 11am 13th January 2010 PST

[Austin Chau (Google employee)]

A little friendly reminder that we will be hosting virtual office hours in
Wave Sandbox on -

Wednesday, 13th January 2010 at 11:00:00AM GMT-8 hours PST (San Francisco
time).

You can use this tool to see what time it is in your timezone
http://www.timeanddate.com/worldclock/converter.html?year=2010&month=1&day=13&hour=11&min=0&sec=0&p1=224&p2=240

Office hours are also listed on this calendar (which defaults to US
Pacific timezone):
http://code.google.com/events/calendar/

You can add it to your calendar from there, and if your calendar is
setup appropriately, it should show up at your local time.
You can also enable a second timezone in your calendar (MTV + SYD),
that helps in converting.

We will create a public sandbox Wave and post a link to it in this
group when office hours begins.

See you there!

Re: [Google Wave APIs] Child blip to last blip in a wave

[Austin Chau (Google employee)]

This is not possible with the API's current representation
of parent and children blips. In order for you to iterate over the blips in
the "conversation" order, the API needs to expose the conversation model.
You can read more about the model in the Wave Protocol specification:

http://www.waveprotocol.org/draft-protocol-specs/wave-conversation-model
(particularly
"Conversation Manifest Document")

We do plan to expose the conversation model in the API at a later date, so
please stay tuned to the blog and forum for updates.

Hey Eric, sorry that was a mistake on that line.  I was looking at my
calendar with a different timezone, sorry about that.  I will post the

You can check the developer calendar which includes our weekly office hours

Re: [Google Wave APIs] Wave API Office Hours Wed Dec 15th 11am (US Pacific timezone)

[Austin Chau (Google employee)]

This week's office hours will take place at the following time:

San Francisco (U.S.A. - California) - Wednesday, December 14, 2009 at
11:00:00 AM

London (U.K. - England) - Wednesday, December 14, 2009 at 7:00:00 PM

You can use this tool to see what time it is in your timezone

http://www.timeanddate.com/worldclock/converted.html?month=12&day=14&year=2009&hour=11&min=0&sec=0&p1=224&p2=136

Office hours are also listed on this calendar (which defaults to US Pacific
timezone):

http://code.google.com/events/calendar/

You can add it to your calendar from there, and if your calendar is setup
appropriately, it should show up at your local time.

You can also enable a second timezone in your calendar (MTV + SYD), that
helps in converting.

We will create a public sandbox Wave and post a link to it in this group
when office hours begins.

See you there!

Re: [Google Wave APIs] Re: robots (self)added message gets appended twice

[Austin Chau (Google employee)]

I believe this is a result from issue 354.  This problem is specific to the
Java client library, not a backend issue and it is triggered when you do
Wavelet.appendBlip().  To get around this for now, you can do this

Blip blip = Wavelet.appendBlip();
blip.delete();
blip.getDocument().append("THIS ONLY APPEND ONCE");

ah, this event might not be able available in the current release of the

Hi,

If a wavelet creates another another wavelet, you should be able to catch
the WAVELET_CREATED event, given that you have registered for it.

Re: [Google Wave APIs] Gadget API needs a bit of help?

[Austin Chau (Google employee)]

Hi,

You can probably do some of the behaviors you described by having your own
scheme of in your state data.   For instance, you adopt the format for your
state data such that you would append the username before the actual value
to indicate the data provider, ie foo=aus...@wavesandbox.com_data

This is not perfect, but in general a lot of things can be possible with a
little bit more works, in the way how you send data and how you interpret
and propagate data.

Re: [Google Wave APIs] wasSelfRemoved() is not propagated to robot

[Austin Chau (Google employee)]

Hi,

The WAVE_SELF_REMOVED event is not currently sent to the robot, this will
probably changed in the future iteration.  We will keep you guys updated.

[Google Wave APIs] Re: multiple gadgets sharing state

1) You are correct. The callback mechanism provided by gadget library is
only connected to the wave server.

2) Yes.  When robot changed gadget states  your gadget will receive the
callback.

[Google Wave APIs] Re: multiple gadgets sharing state

[Austin Chau (Google employee)]

No gadget states are specific to each gadget and not shared among other
gadgets within the same wave.

There are several ways to maintain "state" among different gadgets of the
same wave, you can maintained your own persistent storage on remote server
and use some crossdomain mechanism (jsonp, script injection, etc) to share
data.  You can also use wave robot to maintain data for you and store them
on the wave data document.

[Google Wave APIs] Re: Cron Tutorial

We do not have documentation for the current cron setup for robot, due the
reason you have mentioned that we are soon replacing it with a more robust
mechanism.  In the meanwhile, please check out the sample robot Stocky which
uses the current cron setup -

http://google-wave-resources.googlecode.com/svn/trunk/samples/extensions/robots/java/stocky/

Essentially
you specify your cron spec in the capabilities.xml.  Map a handler to the
URL in web.xml -

/_wave/robot/fetchupdate

Since I don't have the full context of your code, I am suspecting that your

[Google Wave APIs] Re: Talking to a Gadget from a Robot

[Austin Chau (Google employee)]

The way to do what you described is by setting gadget states from within the
gadget.  So when a viewer populate some data in an input field from your
gadget, you would set a wave state to represent this data.  Setting a gadget
state would trigger DOCUMENT_CHANGED event to the robot.  The robot in turn
can retrieve this event and its associated context, including the triggering
blip which contains the gadget.  From there the robot can get the reference
to the gadget and its gadget states.

[Google Wave APIs] Re: Text appended twice in blip

[Austin Chau (Google employee)]

Hi Karan,

Sorry that this bug hit you as well, we have already filed a request for it.
 You can track it with this bug report -

http://code.google.com/p/google-wave-resources/issues/detail?id=354&sort=-id&colspec=Stars%20ID%20Type%20Status%20Priority%20Milestone%20Owner%20Summary%20Internal

We know exactly what is causing this and when fix is pushed to production we
will let you guys know.

In the mean while the workaround to not have doubling of the text you can do
this -

Blip newBlip = wavelet.appendBlip();
newBlip.getDocument().delete();
newBlip.getDocument().append("hello");

This should only print the text once.

[Google Wave APIs] Re: Less frequent updating

Cron job can recreate the blip context.  Check out the sample robot Stocky.
 It persists wave, wavelet and blip IDs, so that the cron call can later
recreate the context.

We
have identified the problem and the changes should be up in our next push.
 In the meantime you can do blip.getDocument().delete() before you call
blip.getDocument().append(), that should be the temporary fix to avoid
doubling up the text.

You can use "+data" in your robot name to tag extra bit of data to your

add robot+createlea...@appspot.com  and
robot+createt...@appspot.com  respectively.
 And inside your robot implementation you can check to see what the trailing
+ data is and react accordingly.

[Google Wave APIs] Re: How could a robot remove itself from the wave?

[Austin Chau (Google employee)]

Although the method for removing a participant is available in the client
libraries (Wavelet.removeParticipant() in Java), we haven't finalized the
policy around how removal should work hence the operation right now is
ignored on the server.

Feel free to a file feature request to push this higher in the priority
chain.  Thanks

[Google Wave APIs] Re: Fundamental question - what does "context"...um...do?

[Austin Chau (Google employee)]

No you have no control context.  Context is managed sent by the server.  If
you need to maintain states, you need your own datastore or you can use the
DataDocument from Wavelet.

[Google Wave APIs] Re: Fundamental question - what does "context"...um...do?

[Austin Chau (Google employee)]

Essentially you can think of event handler/context as callback (endpoint)
with data (context).  Imagine you have a handler for a particular type of
wave event.  When that event has occurred, the Wave server could trigger
your endpoint with this notification.  Associated with this notification, is
the "context" data that are sent along with it.  So that in your handler,
you can actually retrieve the plain text data of the blip.

[Google Wave APIs] Re: Wavelet.getRootBlip() -- Do I understand something wrong?

[Austin Chau (Google employee)]

Basically you need a permanent storage that you manage on your own (not
provided by the API) to maintain the context data for each blip.  That's
what I meant by your own datastore to keep track of the blip ids and
associated data.  Take a look at the sample robot Stocky which has a
persistence layer to remember blips data with JDO on AppeEngine -

http://google-wave-resources.googlecode.com/svn/trunk/samples/extensions/robots/java/stocky/src/robot/

Yes you can do that in Java.  The two client libraries mirror each other

you use this method from Wavelet -

[Google Wave APIs] Re: Wavelet.getRootBlip() -- Do I understand something wrong?

[Austin Chau (Google employee)]

So yes, when a blip is out of context you would have no way to retrieve its
document content from the event callback alone.  What can you do now is
maintain the context on your own with a datastore backend.  Essentially
keeping track of all wavelet and blip ids for lookup.
We know that this is not ideal and we are working on this as speak to remove
the limited context on callback.  Stay tuned for updates.

[Google Wave APIs] Re: Robot notified when it is added as participant?

[Austin Chau (Google employee)]

The event you want to catch is EventType.WAVELET_SELF_ADDED
This event type does not need to be explicitly registered for, it is added
by default to all robot.

I am seeing the same thing.  This is a bug with the insertStyledText().  I

[Google Wave APIs] Re: Wavelet.getRootBlip() -- Do I understand something wrong?

[Austin Chau (Google employee)]

Hi,
To get the root blip id in your scenario -

wave.appendBlip().getDocument().append(wavelet.getRootBlipId());

This would work because it does not require "context" of a grandparent blip.
 The reason that you are getting exception is because the context associated
with an event callback only goes back its immediate parent.  So in your case
if the triggering event is resulted from a grandchild blip away from root,
it will no longer has context to recreate the root blip when you invoked
wavelet.getRootBlip() - thus you will get a null reference.

Hope it helps,
Austin

[Google Wave APIs] Re: Outgoing HTTP connections within a appengine-hosted Wave bot

[Austin Chau (Google employee)]

The requirement is specific to the platform.  So yes, Python client library
has it own specific way to do fetch.  You would use the fetch() method provided
by the google.appengine.api.urlfetch package.

[Google Wave APIs] Re: Outgoing HTTP connections within a appengine-hosted Wave bot

[Austin Chau (Google employee)]

Hi,
Since robots is hosted within Google Appengine(GAE) and GAE only allows
external HTTP connection be made with java.net.URLConnection, other
mechanism might not be enabled.  You may want to find out if the client
library you are using is using something other than URLConnection, in that
case you would need to write your own fetch mechanism.  An example of how to
fetch content over HTTP can be found in this link.  You can check out the
fetchUrl()method -

[Google Wave APIs] Re: Not possible to delete image element?

[Austin Chau (Google employee)]

Hi,
I believe the problem is that you are trying to delete element using
absolute index position.  The moment you delete the first element in your
loop, the absolute positions for the other elements have changed as a
result.  This is why the subsequent deletion would fail.  If you want to
delete all the elements of a blip, you can use the delete() method from
TextView.

Hope it helps,
Austin

[Google Wave APIs] Re: Cursor Position

[Austin Chau (Google employee)]

The annotateSelection action in the menuHook of extension installer would
only trigger if something is highlighted on the wave client.  And this is
currently the only way to obtain the user cursor position.  So whatever text
that is highlighted by the user just before the extension installer is hit,
an annotation of your specific naming will surround those text when your
robot receives the event.

It looks fine.  You can make sure it is the right button that is triggering
the event by -
 if (e.getButtonName().equals(BUTTON_NAME)) {
FormView formView = currentBlip.getDocument().getFormView();
FormElement element = formView.getFormElement("input");
wavelet.appendBlip().getDocument().append(element.getValue());
  }

[Google Wave APIs] Re: How to append text following an annotation?

[Austin Chau (Google employee)]

You can insert a space after the anchor text and only annotate the anchor
text just before the trailing.  Quick sample code -
  private void addAnchorLink(Blip blip, int startIndex, String url, String
anchorText) {
anchorText += " ";
TextView textView = blip.getDocument();
textView.insert(startIndex, anchorText);
textView.setAnnotation(new Range(startIndex, startIndex +
anchorText.length() - 1),

[Google Wave APIs] Re: Adding a HTML Anchor to a Wave via the Robot Protocol.

[Austin Chau (Google employee)]

You can try to add a trailing space at the end of the anchor text and
annotate the text just before the trailing space.  This should prevent the
autolinking to continue on.

Thanks Greg, that would also work nicely without having to deal with
annotation :)

Can you file a feature request to my documentation to include list of native

[Google Wave APIs] Re: Included OAuth code causing "The class not persistable" error

Hi Eric and Nicolas,
If you are guys are using Eclipse with GAE plugin, try running the
"project->clean" which will force rebuilding the entire project includeing
the enhance target.

[Google Wave APIs] Re: Adding a HTML Anchor to a Wave via the Robot Protocol.

[Austin Chau (Google employee)]

Hi,
If you just append the straight URL, Wave will automatically linkify into an
anchor link with the URL as its anchor text.  But it seems like you would
like to have customized anchor text, you would need annotation to do that.
 The annotation name for anchor link is "link/manual", this is an example
how this is done -

  TextView textView = yourBlip.getDocument();
  String content = textView.getText();
  String anchorText = "click here";
  textView.insert(content.length(), anchorText);

  int start = content.length();
  int end = start + anchorText.length();

  textView.setAnnotation(new Range(start, end), "link/manual", "
http://www.google.com";);

This snippet above would add an anchor text at the end of a blip and
annotate it with the URL http://www.google.com.
