Perl arrays and loop through array
Hi All

I need to get <STDIN> from a user. the <STDIN> is a range of number delimited by "," (comma) and can be with range delimited by "-".

Example: 1,2,3,4-9,12,15,34-36,70

Now I need to get this from the user and go on each number and "Do something"... but when trying to do this as above the loop use the array element as string.

Code:
my $str = "1, 2 ,3, 4,6 -10,11 - 15,16, 17";

$str =~ s/\s+//g;
$str =~ s/-/\.\./g;
my @arr = split /,/, $str;
for (@arr){
    my $i = $_;
    print "==>>> $i\n";
}

The result of this is:
Code:
==>>> 1 ==>>> 2 ==>>> 3 ==>>> 4 ==>>> 6..10 ==>>> 11..15 ==>>> 16 ==>>> 17

and not:
Code:
==>>> 1 ==>>> 2 ==>>> 3 ==>>> 4 ==>>> 6 ==>>> 7 ==>>> 8 ==>>> 9 ==>>> 10 ==>>> 11 ==>>> 12 ==>>> 13 ==>>> 14 ==>>> 15 ==>>> 16 ==>>> 17

as wanted...

Any suggestions? Thank you all.

locale::codes::langfam5.18

Locale::Codes::LangFam(3pm)				 Perl Programmers Reference Guide			       Locale::Codes::LangFam(3pm)

NAME

       Locale::Codes::LangFam - standard codes for language extension identification

SYNOPSIS

	  use Locale::Codes::LangFam;

	  $lext = code2langfam('apa');		       # $lext gets 'Apache languages'
	  $code = langfam2code('Apache languages');    # $code gets 'apa'

	  @codes   = all_langfam_codes();
	  @names   = all_langfam_names();

DESCRIPTION

       The "Locale::Codes::LangFam" module provides access to standard codes used for identifying language families, such as those as defined in
       ISO 639-5.

       Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 639-5
       language family codes will be used.

SUPPORTED CODE SETS

       There are several different code sets you can use for identifying language families. A code set may be specified using either a name, or a
       constant that is automatically exported by this module.

       For example, the two are equivalent:

	  $lext = code2langfam('apa','alpha');
	  $lext = code2langfam('apa',LOCALE_LANGFAM_ALPHA);

       The codesets currently supported are:

       alpha
	   This is the set of three-letter (lowercase) codes from ISO 639-5 such as 'apa' for Apache languages.

	   This is the default code set.

ROUTINES

       code2langfam ( CODE [,CODESET] )
       langfam2code ( NAME [,CODESET] )
       langfam_code2code ( CODE ,CODESET ,CODESET2 )
       all_langfam_codes ( [CODESET] )
       all_langfam_names ( [CODESET] )
       Locale::Codes::LangFam::rename_langfam  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Codes::LangFam::add_langfam  ( CODE ,NAME [,CODESET] )
       Locale::Codes::LangFam::delete_langfam  ( CODE [,CODESET] )
       Locale::Codes::LangFam::add_langfam_alias  ( NAME ,NEW_NAME )
       Locale::Codes::LangFam::delete_langfam_alias  ( NAME )
       Locale::Codes::LangFam::rename_langfam_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangFam::add_langfam_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangFam::delete_langfam_code_alias  ( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes::API man page.
