| ab5tract | m: my $x=9; my $y=10; say ($x cmp $y ~~ Same|Less) ?? "ordered" !! "unordered"; | 02:19 | |
| camelia | ordered | ||
| ab5tract | renormalist: ^^ | ||
| == is for numeric operations, but ~~ (smartmatch) does what you mean here | 02:20 | ||
| m: my $x=10; my $y=10; say ($x cmp $y ~~ Same|Less) ?? "ordered" !! "unordered"; | 02:21 | ||
| camelia | ordered | ||
| ab5tract | m: my $x=11; my $y=10; say ($x cmp $y ~~ Same|Less) ?? "ordered" !! "unordered"; | ||
| camelia | unordered | ||
| ab5tract | Regarding the last test case you linked to, I think ‘is’ cascades through a variety of equality check options, though I would have to check the source to be sure | 02:25 | |
| Switching to ok and smartmatch works fine though | |||
| m: use Test; ok [Nil] ~~ [Nil], “no warnings allowed” | |||
| camelia | ok 1 - no warnings allowed | ||
| ab5tract | Hope it helps! | 02:26 | |
| renormalist | ab5tract: yes, it helps, thanks. For some reason I was staring only at the module, not the test is(). Switching to ok/~~. Thanks. | 02:35 | |
| ab5tract | My pleasure! | ||
| Nice idea with the type junctions btw | 02:36 | ||
| You can also put them into a subset. Maybe not really useful in this case but if you ever end up with more junction candidates it might come in handy | 02:40 | ||
| m: subset LessOrEqual where Same|Less; say (9 cmp 10 ~~ LessOrEqual) ?? "ordered" !! "unordered"; | |||
| camelia | ordered | ||
| renormalist | m: my $x="9"; my $y="10"; say ($x cmp $y ~~ Same|More) ?? "ordered" !! "unordered"; | 02:42 | |
| camelia | ordered | ||
| renormalist | m: my $x; my $y="10"; say ($x cmp $y ~~ Same|More) ?? "ordered" !! "unordered"; | 02:43 | |
| camelia | Use of uninitialized value $x of type Any in string context. Methods .^name, .raku, .gist, or .say can be used to stringify it to something meaningful. unordered in block <unit> at <tmp> line 1 |
||
| renormalist | though this uninitialized warning - can ~~ also handle that without warning? | ||
| I think it does everything as long as there is a value and therefore a type. Having nothing does the right thing, not sure why it insists on the warning. | 02:45 | ||
| (Ok, the warning is important as it does NOT do the right thing.) | 02:48 | ||
| I guess I need to decide the semantics. Like here use a copy $xcopy and //= assign it to $y. | 02:51 | ||
| m: my $x; my $y="10"; my $xcopy = $x; $xcopy//=$y; say ($xcopy cmp $y ~~ Same|More) ?? "ordered" !! "unordered"; | 02:52 | ||
| camelia | ordered | ||
| ab5tract | m: my $x; my $y="10"; say (($x // “0”) cmp $y ~~ Same|More) ?? "ordered" !! "unordered"; | 02:53 | |
| camelia | unordered | ||
| renormalist | (m: my $x; my $y=10; say (($x // “0”) cmp $y ~~ Same|More) ?? "ordered" !! "unordered"; | 02:54 | |
| m: my $x; my $y=10; say (($x // “0”) cmp $y ~~ Same|More) ?? "ordered" !! "unordered"; | |||
| camelia | unordered | ||
| renormalist | m: my $x; my $y=10; say (($x // 0) cmp $y ~~ Same|More) ?? "ordered" !! "unordered"; | 02:55 | |
| camelia | unordered | ||
| renormalist | hm | ||
| ab5tract | It makes sense, no? The condition is false, so we get “unordered” | 02:57 | |
| m: my $x //= my $y="10"; say ($x cmp $y ~~ Same|More) ?? "ordered" !! "unordered"; | |||
| camelia | ordered | ||
| renormalist | yeah, I'm probably confusing things while also looking at my actual sort module code | 02:58 | |
| ab5tract | Gotcha | ||
| renormalist | Ok, anyway, I think I got it. Will get some sleep now. Thanks. | 02:59 | |
| ab5tract | I’m heading to sleep as well. Till next time! | ||
| renormalist | good night | ||
