11:41 <bremner> does anyone know of a nice example of a string formatting dsl that is just s-expressions, and doesn't use a format string?

12:17 <ns12> bremner: You could write your string as a list of (sub)strings, which would allow the use of quasiquotation. Then, (apply string-append ...) to produce a single string.

15:07 <tonyg> imagining a reasonable ~j there

15:55 <ns12> tonyg: What library does that string formatting syntax come from?

16:49 <tonyg> ns12: ~a is standard. ~j is an easy subroutine

22:28 <scubagear[m]> How easy is it to add a JS backend to racket? Is there some isolated part of the racket runtime that lets one add a backend?
