14:58 <kengruven> i'm trying to use libgit2 (the racket module), and i can't figure out git_revwalk_next. it's an FFI wrapper for a func which takes a pointer to a struct. i tried passing a (malloc _git_oid) value to it, but it fails with "argument is not non-null `git_oid' pointer". what am i missing?

15:51 <hdbbdh> Suppose that we have (define x ''a), how can I get '''a from variable x

15:51 <hdbbdh> (quote x) doesn't work because it gives 'x

15:54 <bremner> hdbbdh: `(quote ,x) seems to work

15:58 <bremner> that expands to (quasiquote (quote (unquote x))) ; not sure if that is any better.

16:05 <hdbbdh> I see, thanks!
