Perl6: .sort() doesn't use overridden cmp


Perl6: .sort() doesn't use overridden cmp

may help you . I think that's a case of Broken By Design. Consider the following snippet:
code :
my $a = Point.new(:3x, :2y);
my $b = Point.new(:2x, :4y);

say &infix:<cmp>.WHICH;
say $a cmp $b;

{
    multi sub infix:<cmp>(Point $a, Point $b) { $a.y cmp $b.y || $a.x cmp $b.x }
    say &infix:<cmp>.WHICH;
    say $a cmp $b;
}

say &infix:<cmp>.WHICH;
say $a cmp $b;
constant CMP = &infix:<cmp>;
multi sub infix:<cmp>(Point $a, Point $b) { ... }
BEGIN CMP.wrap(&infix:<cmp>);

wish helps you The Sort step takes long because you are running low on memory for your sort operation. This means it will start sorting on disk, and that is horribly slow. Options to this is to use some 3rd party sorting components like NSort.
Otherwise you can do the following:
code :
SELECT * FROM servera.databasea.tablea ORDER BY id, modifiedon

SELECT id, modifiedon FROM serverb.databaseb.tableb ORDER BY id, modifiedon

wish help you to fix your issue The sort method takes a sub as optional argument. If its arity is 1, it uses the return value as comparison operands; if its arity is 2, you can manually do the comparison between elements however you see fit by returning one of Less, Same or More.
Given your example, we can sort by first name like this:
code :
@allRecords.sort(*.[1]);
@allRecords.sort(-> $a, $b {
    $a[2] cmp $b[2] || $a[1] cmp $b[1] || $a[0] cmp $b[0]
});
@allRecords.sort(*.[2...0]);
.comb(2).list.rotate(-1).join

seems to work fine First, thanks for using my perl6 docker container. I will try a few things with your program, to find out what's really the problem. I gather you want to know, in general, what happens with these kind of programs in docker, and not in the particular docker-compose environment, right?
Run the program from inside the docker container
code :
docker run -it --rm  --entrypoint sh  jjmerelo/alpine-perl6
docker run -it --rm -v $PWD:/app  jjmerelo/alpine-perl6 /app/app.pl

wish helps you I am trying to get a list of directories by age in Perl6, which is equivalent to Bash ls -tl | grep ^dr but I am unsure how to sort the results by age, if this is even possible , I think what you're looking for is:
code :
dir(test => *.IO.d) .sort: *.changed
# Call `foo` with two arguments `bar` and `baz`:
foo(bar, baz);

# Juxtapose identifier `foo` with a single `List` of 2 elements (bar, baz): 
foo (bar,baz);

# Juxtapose identifier `foo` with two `List`s: 
foo (bar,baz), (qux, waldo);
