Subject: Re: [Caml-list] looping recursion
Date: Tue, 27 Jul 2004 18:05:26 -0700	[thread overview]
Message-ID: <16646.64470.304530.264731@soggy.deldotd.com> (raw)
In-Reply-To: <d849ad2a04072717275c865d9f@mail.gmail.com>

After sufficient googling I finally found a post which yields the answer :

let readfile chan =
  let rec loop rlst =
    let line, eof = 
      try
        (input_line chan), false
      with
        | End_of_file -> "", true
    in
      if not eof then
        loop (line :: rlst)
      else
        List.rev rlst
  in
    loop []
;;

but then it gets better.  Imagine my surprise when the following failed:

let data = readfile (open_in "data") in
let split_lines = List.map
                    (fun line ->
                       line;
                    )
                    data
in
  print_string "Done.\n";;

That's just not good !  I can't even use standard map without the
stack blowing up ?  This is a Bad Thing (TM).

Oh but wait. I peruse the manual.  map_rev is what I want.

So I'm going to make a bold statement that .map which blows up
shouldn't even exist and .rev_map should be renamed to .map.

Naturally someone will be telling me very shortly why you can't do this...

Brian
