locale - Perl pragma to use or avoid POSIX locales for built-in operations SYNOPSIS
@x = sort @y; # Unicode sorting order { use locale; @x = sort @y; # Locale-defined sorting order } @x = sort @y; # Unicode sorting order again DESCRIPTION
This pragma tells the compiler to enable (or disable) the use of POSIX locales for built-in operations (for example, LC_CTYPE for regular expressions, LC_COLLATE for string comparison, and LC_NUMERIC for number formatting). Each "use locale" or "no locale" affects statements to the end of the enclosing BLOCK. Starting in Perl 5.16, a hybrid mode for this pragma is available, use locale ':not_characters'; which enables only the portions of locales that don't affect the character set (that is, all except LC_COLLATE and LC_CTYPE). This is useful when mixing Unicode and locales, including UTF-8 locales. use locale ':not_characters'; use open ":locale"; # Convert I/O to/from Unicode use POSIX qw(locale_h); # Import the LC_ALL constant setlocale(LC_ALL, ""); # Required for the next statement # to take effect printf "%.2f ", 12345.67' # Locale-defined formatting @x = sort @y; # Unicode-defined sorting order. # (Note that you will get better # results using Unicode::Collate.) See perllocale for more detailed information on how Perl supports locales. perl v5.16.2 2012-10-11 locale(3pm)
