Re: [Caml-list] input_line ... have i gone mad?

[Nicolas Wu]

ah! :$ how embarassing. i assumed that an empty
standard input stream would be achieved by hitting enter,
rather than closing it with ctrl-d .. didn't think of that, it
does work fine d'oh!

thanks again!

Re: [Caml-list] input_line ... have i gone mad?

[Francois Burgisser]

With the standard input, to get the End_of_file exception thrown, you should 
close the stream by pressing ctrl+d.

[Caml-list] input_line ... have i gone mad?

[Nicolas Wu]

Hey all, i'm trying to write a very simple program using input_line to grab
input from stdin ... but it is going horribly wrong! try putting the 
following
in a toplevel:

<<cut>>
open Printf;;

let main () =
try
printf "start";
while true do
  printf "just before"; flush stdout;
  let line = input_line stdin in
  printf "print the line %s" line
done
with End_of_file ->
printf "should exit";;

main () ;;
<<cut>>

on my machine, it works fine, but never reaches the "should exit" line-
it seems like the End_of_file exception is never thrown - this is the same
even if i use read_line () instead of input_line.... what am i doing wrong?

thanks!

nick
