NAMESort::Sub::by_perl_code - Sort by Perl codeVERSIONThis document describes version 0.120 of Sort::Sub::by_perl_code (from Perl distribution Sort-Sub), released on 2020-05-25.SYNOPSISGenerate sorter (accessed as variable) via Sort::Sub import:use Sort::Sub '$by_perl_code'; # use '$by_perl_code<i>' for case-insensitive sorting, '$by_perl_code<r>' for reverse sorting my @sorted = sort $by_perl_code ('item', ...); Generate sorter (accessed as subroutine): use Sort::Sub 'by_perl_code<ir>'; my @sorted = sort {by_perl_code} ('item', ...); Generate directly without Sort::Sub: use Sort::Sub::by_perl_code; my $sorter = Sort::Sub::by_perl_code::gen_sorter( ci => 1, # default 0, set 1 to sort case-insensitively reverse => 1, # default 0, set 1 to sort in reverse order ); my @sorted = sort $sorter ('item', ...); Use in shell/CLI with sortsub (from App::sortsub): % some-cmd | sortsub by_perl_code % some-cmd | sortsub by_perl_code --ignore-case -r DESCRIPTIONThis:use Sort::Sub '$by_perl_code', {code=>'length $_[0] <=> length $_[1]'}; my @sorted = sort $by_perl_code @data; is equivalent to: my @sorted = sort { length $a <=> length $b } @data; Case-sensitivity flag "i" is not relevant. SORT ARGUMENTS"*" marks required arguments.code*str.Either compiled code or string code excluding the "sub {" and "}" enclosure. Code should accept two arguments (the operands to be compared) and is expected to return -1, 0, -1 like the builtin "cmp" operator.
