More on locale

[mikeh@minivend.com]

Hi all,

I found that there is no way that the searching in MV3.14 will work
with the LC_CTYPE setting being done on the fly.

You might get reasonable results if you put 'use locale' in some places
in Search.pm, always just before I compile the search function. I won't
patch MV for distribution because of possible side effects...  but here
is a patch against 3.14-3:

*** /home/reference/minivend-3.14-3/lib/Vend/Search.pm	Mon Aug 16 08:07:15 1999

  ("coordinate search\ncode is: $code\nfunc is:\n$f")
  	if ::debug(0x10);
  # END DEBUG
+ 		use locale;
  		$f = eval $f if $f;
  		die($@) if $@;
+ 		no locale;
  		$code .= <<EOF;
  $range_code
  $ender

  		return ($f);
  	}
  #::logError("code is $code");
+ 	use locale;
  	$limit_sub = eval $code;
  	die "Bad code: $@" if $@;
  	return ($limit_sub, $f);

*** 739,744 ****
--- 742,748 ----
  	if ::debug(0x10);
  # END DEBUG
  
+ 	use locale;
      my $func = eval $code;
      die "bad pattern: $@" if $@;
  
***************
*** 784,789 ****
--- 788,794 ----
  	if ::debug(0x10);
  # END DEBUG
  
+ 	use locale;
      my $func = eval $code;
      die "bad pattern: $@" if $@;
  

In MiniVend 4, I am integrating and testing this throughout.  I have
successfully demonstrated searching for and sorting on different locales;
dynamic [tag time] outputs, and other niceties.  It will be controlled by
setting LC_CTYPE, LC_COLLATE, and LC_TIME keys in the MiniVend Locale settings.
So when you do a locale change for the user, all of this will roll through if
you set the appropriate locale:

	Locale de_DE  LC_CTYPE de_DE
	Locale de_DE  LC_TIME  de_DE
	# Example of keeping sorting for a US-specific database
	Locale de_DE  LC_COLLATE en_US

I haven't decided whether I should test for availability of the locale and
do this automatically; any input is welcome.
