nice tool! Tried searching for friends by first name. Some dont work with just first name. Might need to do finagling with the regex.

  It doesn't use a regex on the full name; FB provides separate fields and FbFriends searches those with a simple ORed string compare. So I'm surprised it's not working for you. I wonder if whatever FB uses to split the name up (i.e. their regex) isn't doing the right thing for your friends. Or it could be a bug. I'll look into it.

What are some use cases?
- icambron 14y ago
  The use case I built if for was that I wanted wedding guests responding to an invite to be able to identify their +1 as one of their FB friends. But I suppose the most common use case would be inviting a list of friends to an application. I've seen a number of apps that have that, and as far as I know, they all roll their own dialog for doing that.

Very nice! I might try to use it later today for a project I've had cooking for a while. What is the structure of the friends object after the dialog closes? What information do we get about them?
- icambron 14y ago
  I need to document that better. Here's what's passed to the callback: [ { id: anFbId, name: "Some guy", picture: "a url" }, //other friends in the multi-selection case ] If there's other kinds of information you'd want, I'd love some feedback on that.

    Does facebook expose their email address to you? I would like to use this to allow people to invite their friends to sign up for my service but I'm not sure how I would do that. I guess I could use facebook APIs to send them a message in lieu of email.

      When you set up an FB application, it lets you specify what information you want the user to make available to you. When the user approves the app, the dialog specifies what info the app is asking for. I assume that "friends' email" is one of those options. Then FbFriends would be able to ask for that info. So to support this, I'd need to: 1. expose to you as the developer the ability to specify the list of attributes to request from FB (hardcoded right now). 2. just pass the object I get from FB straight to the callback instead of mucking with the object (makes some things, like the picture, a bit more complicated). 3. document how to set up the Facebook application to get the right permissions from the end-users. That all seems reasonable, and I'll take a crack at it later today when I'm done with my 9-5.

        That would be pretty awesome! Let me know how it goes or if I can give any input at all.

        So I'm writing the feature that lets you specify what fields you want and will pass the resulting FB object directly back to you (edit: now done and in the trunk). However, you can't get the email addresses of friends. From https://developers.facebook.com/docs/reference/login/email-permissions/ https://developers.facebook.com/docs/reference/login/email-p...: "Note: There is no way for apps to obtain email addresses for a user's friends."
