Sam Tobin-Hochstadt on Composable and Compilable Macros

Meetup: http://www.meetup.com/papers-we-love/events/220021234/ Paper: https://www.cs.utah.edu/plt/publications/macromod.pdf Slides: http://bit.ly/1KNwpjC Audio: https://www.mixcloud.com/paperswelove/sam-tobin-hochstadt-on-composable-and-compilable-macros/ -------------------------------------------------------------------------------------------------------------------------------------------------- Sponsored by Two Sigma (@twosigma), The Ladders (@TheLaddersDev), and LispNYC (@lispnyc) -------------------------------------------------------------------------------------------------------------------------------------------------- Description --------------- "Composable and Compilable Macros" introduces the Racket module system, which addresses the following problem: When you have macros that run programs at compile-time, how does this interact with separate compilation and ahead-of-time compilation. The paper introduces "phases", which enable Racket to behave the same regardless of when and how you compile your program. It also introduces the idea of writing different modules in different languages, which is now used for systems like Typed Racket.

He has worked on dynamic languages, type systems, module systems, and metaprogramming, including creating the Typed Racket system and popularizing the phrase “scripts to programs.” He is a member of the ECMA TC39 working group responsible for standardizing JavaScript, where he co-designed the module system for ES6, the next version of JavaScript. He received his PhD in 2010 from Northeastern University under Matthias Felleisen.

Racket is the best programming language that embraces the premise that there is no best programming language. In other words, Racket is designed to support the creation of programming languages which can then be used to build programs. Using Racket, we have built program languages ranging from large, general-purpose languages ...
