The responses I've gotten so far (amazingly fast, thanks folks!) show that I need to put more constraints on this request. In particular, this indenter has to be: 1) Stand-alone, 2) Small, 3) Portable (assume C or Scheme is available, *nothing else*) 4) Free (including of constraints, hence no GNU code). (Don't worry, if it's PD, and I improve it, the improvements will be PD) Has anyone here ever thought of writing a variant of (read) [call it (read-with-comments)] that retains comments? It would make writing a "keeps comments" pretty printer much easier... Again, please reply by mail; I'll summarize and post. Thanks! -- // David A.

RE: reasonable Lisp indentation algorithms... I believe there are a couple of MIT AI Lab notes available that address this issue. I seem to recall reading somewhere about a code formatter that even does its job in linear time, which sounds pretty amazing to me. In any case, off the top of my head, it seems to me that you should be able to 1) copy your Lisp's standard readtable and hack it so as not to ignore comments, and 2) somehow integrate the results with XP, Dick Waters' highly-extensible pretty-printing package, which is available via FTP to wheaties.ai.mit.edu. Hope this helps!
