Top Forums Shell Programming and Scripting Perl: code efficiency for gmtime Post 302218926 by KevinADC on Sunday 27th of July 2008 03:09:45 PM

The function should do all the date formatting and return the string ready to use. And don't use concatenation when simple string constructors will suffice.

Code:
# get datetime
$strdate = format_date((gmtime ())[0..5]);
# write to file
getstore($url, "$strdate.txt") or die "Error: Unable to get page $url";

sub format_date {
   my @t = @_;
   ++$t[4];
   $t[5]+=1900;
   for (@t[0..4]) {
      $_ = $_ < 10 ? "0$_" : $_;
   }
   return "$t[5]$t[4]$t[3]$t[2]$t[1]$t[0]"; 
}

NAME

       Finance::Quote::Cdnfundlibrary  - Obtain mutual fund prices from www.fundlibrary.com

SYNOPSIS

	   use Finance::Quote;

	   $q = Finance::Quote->new;

	   %stockinfo = $q->fetch("canadamutual","fundlib-code"); # Can
       failover to other methods
	   %stockinfo = $q->fetch("fundlibrary","fundlib-code"); # Use this
       module only.

	   # NOTE: currently no failover methods exist for canadamutual

DESCRIPTION

       This module obtains information about Canadian Mutual Fund prices from www.fundlibrary.com.  The information source "canadamutual" can be
       used if the source of prices is irrelevant, and "fundlibrary" if you specifically want to use www.fundlibrary.com.

FUNDLIB-CODE
       In Canada a mutual fund does not have a unique global symbol identifier.

       This module uses an id that represents the mutual fund on an id used by www.fundlibrary.com.  There is no easy way of fetching the id
       except to jump onto the fundlibrary website, look up the fund and view the url for clues to its id number.

LABELS RETURNED

       Information available from fundlibrary may include the following labels:

       exchange method link source name currency yield last nav price.	The link label will be a url location for a one page snapshot that
       fundlibrary provides on the fund.
