Sun 13 Feb 2011 07:05:02 PM UTC, comment #3: Sorry it took so long to get back to you. Use `procedure-arguments' from (ice-9 session). See its docstring for more details. I'll leave this bug open until we decide to do something else with procedure-source...	Andy Wingo <wingo>
Fri 23 Jul 2010 04:46:20 PM UTC, comment #2: I discovered this while debugging a compile failure with LilyPond... LilyPond's autogenerated documentation of its internal procedures uses `procedure-source' to access the signature of a given procedure. Would you recommend a different solution for this?	Patrick McCarty <pnorcks>
Mon 19 Jul 2010 07:22:29 PM UTC, comment #1: It's not possible in general to get the source of a procedure, as variables introduced by macros may have the same name but not be the same variables (they have different identities/marks/gensyms, depending on how you look at it). In addition the output of macro expansion may have free variables referenced with regard to different modules. That said, it is a bug that when debugging you can't get to the expressions, and I do plan to fix that soonish. What do you use procedure-source for? Andy	Andy Wingo <wingo>
Sun 18 Jul 2010 12:02:52 AM UTC, original submission: Hello, I am testing the latest git, and I think I've found a regression (compared to 1.8.7). For a valid procedure definition, Guile returns `#f' for `procedure-source': scheme@(guile-user)> (define (test a) (+ a 1)) scheme@(guile-user)> (procedure-source test) $1 = #f scheme@(guile-user)> The same procedure in Guile 1.8.7 returns valid info: guile> (define (test a) (+ a 1)) guile> (procedure-source test) (lambda (a) (+ a 1)) guile>	Patrick McCarty <pnorcks>
