Dear monks,
I want my perl program to sort just like the system it is running on.
This is trivial on Linux, but somehow seems complicated on Windows and macOS.
I use the following test program
#! perl
use strict;
use warnings;
use utf8;
binmode STDOUT => ':utf8';
my @words = ( "Maria Lenore", "Mária Helena", "María Dolores" );
my @sorted = sort @words;
if ( "@sorted" eq "María Dolores Mária Helena Maria Lenore" ) {
print("Sorted OK\n");
}
elsif ( "@sorted" eq "Maria Lenore María Dolores Mária Helena" ) {
print("Sorted C (ASCII)\n");
}
else {
print("Sort failed: @sorted\n");
}
On Windows, I get
PS C:\Users\Johan> perl locale.pl
Sorted C (ASCII)
PS C:\Users\Johan> perl -Mlocale locale.pl
Sorted C (ASCII)
PS C:\Users\Johan>
Same on macOS.
When I create files with names "Maria Lenore", "Mária Helena" and "María Dolores" they sort correctly in the Explorer (Windows) and Finder (macOS).
How can I have perl use the same sort order as the system?
Windows 10 with Strawberry Perl 5.30
MacOS 10.15 with Perl 5.34.
These versions are a bit old, but I can not imagine I'm the first to try such a sort in 25+ years.
