Erlang: Output Problem

Question

In my erlang web application, there is a list, which contains integers to be printed on the web page. But when the script executes, it prints this, instead of actual list,

Please look at this Image showing characters for unicode codepoint 1, 1, 2, 3, 5, 8, whitespace, codepoint 15

How to format this to gain what I want? Target list is [1, 1, 2, 3, 5, 8, 13, 15]

Imageshack is blocked in China. You should think about using decentralized services, why not your own FTP ? Remember the Skype bug a few days ago... — Tangui, Jan 04 '11 at 15:45
@Tangui: If http://imgur.com ain't blocked in China, one may use it right from within SO interface (button *Image* or keyboard shortcut Ctrl+G). — YasirA, Jan 04 '11 at 15:52
try with [1, 1, 2, 3, 5, 8, 13, 21] ;) sorry;) couldnt resist. — user425720, Jan 04 '11 at 19:45

You should do this:

P = [1, 1, 2, 3, 5, 8, 13, 15],
Show_on_page = io_lib:format("~p",[P]),
Show_on_page.

This will represent any Erlang term on the web page the way you want to see it.

Actually, you could remove the "Show_on_page =" and the last line to get the same result. – Roberto Aloi Mar 17 '11 at 13:14
i just wanted to be more elaborate so that @indranama doesnot get lost here. But thanks for that suggestion – Muzaaya Joshua Mar 23 '12 at 04:58

You Web presentation probably like the values more converted to string (lists).

1> [ integer_to_list(I) || I <- [1,1,2,3,5,8,13,15] ].
["1","1","2","3","5","8","13","15"]

Maybe join them as well depending on your formatting.

2> string:join([ integer_to_list(I) || I <- [1,1,2,3,5,8,13,15] ],",").
"1,1,2,3,5,8,13,15"
