                      Ryan Culpepper on PLT Scheme Macros


A Boston Lisp Meeting will take place on Monday, January 25th 2010 at 1800 at
NEU WVH 366. Ryan Culpepper will speak about PLT Scheme Macros.

Additionally, we will have two 5-minute Lightning Talks, each followed by
2-minute Q&A. Speakers to be announced.

Also, there will be a buffet offered by ITA Software.

1 Ryan Culpepper on PLT Scheme Macros

I will talk about writing macros in PLT Scheme, using the tools I've developed.
The first tool is the macro stepper, which shows the macro expansion of
programs as a series of rewriting steps. The macro stepper is adapted
specifically to the challenges of writing macros in a hygienic macro system
using a base language that is itself composed of layers of macros. I'll
demonstrate how to use the macro stepper and talk about its implementation. The
second tool I'll demonstrate is a specification system for Scheme syntax that
makes macros robust and concise.

I am a graduate student in the PLT group at Northeastern University working on
making macros more powerful and easier to use. I'm interested in exploring new
ways of expressing programs and methods of implementing and supporting program

2 Lightning Talks

At every meeting, before the main talk, there are two slots for strictly timed
5-minute "Lightning Talks" followed by 2 minutes for questions and answers.

The slots for next meeting are still open. Step up and come talk about your pet
project! Contact me at fare at tunes.org.

3 Time and Location

The Lisp Meeting will take place on Monday, January 25th 2010 at 1800 (6pm) at
NEU WVH 366.

Note that we're back on a Monday, and that we're using a new location.

This is at Northeastern University, in the Computer Science building WVH (West
Village H, see http://tmp.barzilay.org/wvh.jpg this picture) when you arrive
from the T on Huntington Avenue near to Parker St (Green E line, stop at
Northeastern Station, or possibly Museum of Fine Arts; you can also walk from
Ruggles on the Orange line). As the number indicates, the room is on the third

Northeastern maps and direction:

Many thanks go to Eli Barzilay for arranging for the room, and to Northeastern
University for welcoming us.

4 Dinner

ITA Software a fine employer of Lisp hackers (disclaimer: I work there), is
kindly purchasing a buffet to accompany our monthly Boston Lisp meeting. Anyone
who attends is welcome to partake.

5 More about the Meeting

The previous Boston Lisp Meeting on Monday, December 14th 2009 had about 30
participants. Sam Tobin-Hochstadt spoke about Typed Scheme. http://

We're always looking for more speakers. The call for speakers and all the other
