Unfortunately, I'm no longer maintaining missinglib since I no longer use OCaml (switched to Haskell). However, the Debian OCaml Team is maintaining a branch of it, so you may want to contact them at [EMAIL PROTECTED] -- John On Thu, Sep 14, 2006 at 02:40:40PM -0400, Ivan Jager wrote: > Could you add this function to missinglib? > > In many of my ocaml programs, I end up writing this function (or > something equivalent): > > (* Should be in List *) > let list_map_some f l = > let rec m n o = > match o with > [] -> n > | x::xs -> > (match f x with > Some v -> m (v::n) xs > | None -> m n xs ) > in List.rev(m [] l) > > > The last time I wrote that function, I had a typo, which cost me a few > hours of debugging other code before I found what was going on. > > Thanks, > Ivan -- System Information: Debian Release: testing/unstable APT prefers unstable APT policy: (500, 'unstable'), (500, 'testing'), (500, 'stable'), (1, 'experimental') Architecture: i386 (i686) Shell: /bin/sh linked to /bin/bash Kernel: Linux 2.6.17-2-686 Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) (ignored: LC_ALL set to en_US.UTF-8) -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
