List Comprehension Library for Scheme?
common-lisp, functional-programming, lisp, list-comprehension, scheme
Solution
- Swindle is primarily a CLOS emulator library, but it has list comprehensions too. I've used them, they're convenient, but the version I used was buggy and incomplete. (I just needed generic functions.)
- However, you probably want SRFI-42. I haven't used it, but it HAS to have fewer bugs than the Swindle list comprehensions.
I don't know which Scheme you use. PLT Scheme bundles Swindle and SRFI-42. Both are supposed to be cross-Scheme compatible, though.
If you use PLT Scheme, here is SRFI-42's man page. You say `(require srfi/42)` to get it.
Problem
I know there is a list-comprehension library for common lisp (incf-cl), I know they're supported natively in various other functional (and some non-functional) languages (F#, Erlang, Haskell and C#) - is there a list comprehension library for Scheme? incf-cl is implemented in CL as a library using macros - shouldn't it be possible to use the same techniques to create one for Scheme?
