| DarthGandalf | Hi, what's the best way to insert a row into a 2d array? When I'm doing @map.splice($index, 0, @map[$index]), it insists on flattening the row to multiple elements, even if I wrap it in [[[]]] | 18:33 | |
| I found a way: @map.splice($index, 0, 0); @map[$index] = @map[$index+1]; | |||
| but that looks awkward | |||
| actually, it shoudl be @map[$i] = @map[$i+1].Array, otherwise they are apparently shared; but the point of a weird dummy parameter in splice still stands | 18:36 | ||

| lizmat | DarthGandalf: and with @map.splice($index, 0, $@map[$index]) ??? | 19:21 | |
| m: my @a = 1,2,3; my @b = <a b c>; dd @a.splice(1,0,$@b); dd @a | 19:37 | ||
| camelia | Array @a = [] Array @a = [1, "a", "b", "c", 2, 3] |
||
| lizmat | hmmm that feels like a deficiency in .splice | ||
| DarthGandalf: could you please make an issue for this? | 19:43 | ||
| It won't get fixed before the 2023.12 release (too risky with possible ecosystem fallout), but the issue should not fall through the cracks | 19:44 | ||
| Nahita | m: my @a = [[12, 3], [4, 5]]; @a.splice(1, 0, [@a[1].clone,]); @a1++; say @a | 20:06 | |
| Raku eval | [[12 3] [4 5 1] [4 5]] | ||
| DarthGandalf | lizmat: done, github.com/rakudo/rakudo/issues/5500 | 21:35 | |
| Nahita: how does '1' appear in the second row there? | 21:36 | ||
| and @a1 in your code is not even an existing variable | 21:37 | ||
| nemokosch | what are you talking about? is this a bridge fault again? | ||
| DarthGandalf | erm. Could be? | ||
| nemokosch | yeah it apparently is | 21:38 | |
| @a[1][2]++ @a1++ | |||
| DarthGandalf | I literally see this (I wonder if bridge bridges it correctly): `m: my @a = [[12, 3], [4, 5]]; @a.splice(1, 0, [@a[1].clone,]); @a1++; say @a <Raku eval> [[12 3] [4 5 1] [4 5]] ` | ||
| nemokosch | the difference between my two expressions is the presence of backticks | ||
| DarthGandalf | I see | 21:39 | |
| nemokosch | 13[6, 'asd'] | ||
| I wonder what happens XD | |||
| actually, it was [1][2][3][4, 5][6, 'asd'] | 21:40 | ||
| well, good to know at least... | |||
