We have Jamison Dance.JAMISON: I am not on mute, I hope.CHUCK: We have Joe Eames.JOE: Hi everybody.CHUCK: We have Tim Caswell.TIM C: Hello.CHUCK: We also have a special guest, that’s Tim Disney.TIM D: Hi.CHUCK: AJ, did you figure out your mute issues? That would be a no. I’m Charles Max Wood from Devchat.tv. And this week, we’re going to be talking about Sweet.js.Before we get started, there is one thing I want to announce really quickly and that is that we have scheduled a Book Club episode for January 10th and that’s going to be with David Herman who wrote ‘Effective JavaScript’. So it’s a pretty slim book, should be easy to get through. But yeah, if you want to follow along with that discussion, then by all means, join in.Alright. Let’s talk about Sweet.js. Has anyone…AJ: Can you hear me now?CHUCK: Yeah.AJ: Okay, cool.CHUCK: So, I went and looked at it. I fiddled with it a little bit. I didn’t have enough time to really get into it the way that I wanted to. It looks really cool though. What kind of gave you the idea of doing something like macros for JavaScript, Tim?TIM D: Well, I guess it’s just something I’ve sort of wanted for JavaScript for awhile. But the main sort of impetus I guess was, I was interning at Mozilla Research this past summer. And Dave Herman who has worked on macros in the past basically said he thought that it was sort of finally possible to do for JavaScript. And so, that was a possible sort of intern project for the summer. And so, that’s what got it started.JAMISON: So can you back up and talk about what macros are, because I’m sure there are lots of people that don’t know and lots of people that hear macros and think like CP process are macros.TIM D: Right yeah, exactly. So, C style macros are the sort of painful and sort of limited. The macros that Sweet.js implements are much more in line with sort of scheme style macros. So,Special Guest: Tim Disney.
