| habere-et-disper | m: 2 == 999.say | 10:22 | |
| camelia | WARNINGS for <tmp>: 999 Useless use of "==" in expression "2 == 999.say" in sink context (line 1) |
||
| habere-et-disper | m: say 2 == 999.say | ||
| camelia | 999 False |
||
| habere-et-disper | m: say( 2 == 999.say ) | 10:23 | |
| camelia | 999 False |
||
| lizmat | m: say 2 == True | ||
| camelia | False | ||
| lizmat | m: say 1 == True | 10:24 | |
| camelia | True | ||
| lizmat | m: say 1 == 999.say | ||
| camelia | 999 True |
||
| habere-et-disper | So == is operating in boolean and not numeric context if one of the operands is a string ? | 10:28 | |
| lizmat | no, == coerces to numeric | 10:29 | |
| m: say +True | |||
| camelia | 1 | ||
| lizmat | and say() returns True | ||
| m: say say "foo" | |||
| camelia | foo True |
||
| habere-et-disper | Can we say cast instead of coerce ? Are they roughly equivalent ? | 10:40 | |
| I got confused in the REPL as "2 == 999.say" gives 999 without False at the end. As does "?( 2 == 999.say )". | 10:46 | ||
| lizmat | the reason the REPL doesn't say False, is because the statement already output something: in that case the REPL does *NOT* show the value of the statemennt | 10:55 | |
| habere-et-disper | (y) | 10:56 | |
| lizmat | re cast vs coerce: in the case of casting, the actual value doesn't change, does it? You e.g. cast a 16bit int into a 32bit int, but not to a string, right? | 11:05 | |
| habere-et-disper | Hmm... I've not made that distinction -- interesting. | 11:10 | |

| Tirifto | m: say 6 ~~ (3 > 2); given 6 { when (3 > 2) { say 1 }; default { say 0 }; } | 14:35 | |
| camelia | True 0 |
||
| Tirifto | Does someone know why ‘given 6 { when (3 > 2) … }’ does not amount to ‘6 ~~ (3 > 2)’, or perhaps rather ‘6 ~~ True’? | 14:40 | |
| antononcube | Is there an easier or shorter way to convert an list of two numbers @pos into a Range object than this one: Range.new(|@pos) | ||
| ab5tract | you could make a local sub called range (or shorter) that does this | 14:41 | |
| but nothing built-in AFAIK | 14:42 | ||
| antononcube | 👍 | ||
| Tirifto | I suppose @pos[0]..@pos[1] is not really shorter or easier. xP | 14:44 | |
| antononcube | @Trifto No, it is not. And that is the answer ChatGPT gave me... | 15:08 | |

| habere-et-disper | Maybe this could work for antononcube ? | 15:44 | |
| m: my @pos=[2,9]; @pos.minmax.WHICH.say | |||
| camelia | Range|2..9 | ||
| ab5tract | ah, nice! I had forgotten that minmax makes a range | 15:47 | |
| antononcube | Hmm.. more precisely "minmax gives a range" ? | 15:49 | |
| @habere-et-disper Thanks -- works nicely! | 15:50 | ||
| habere-et-disper | :] | ||
| antononcube | @habere-et-disper Did you ever use "Text::CodeProcessing" ? | 15:52 | |
| Tirifto | (The range will always start with the smaller coordinate, though.) | 15:53 | |
| antononcube | Good point. But my use case (so far, today) is getting sub-strings from indices. | 15:54 | |
| habere-et-disper | Can I message from here to a specific user behind discord-raku-bot ? | 16:01 | |
| If so, pray tell the invocation ! | |||
| antononcube | @habere-et-disper I think so -- you have to mention their handle prefixed with '@'. | 16:09 | |
| @habere-et-disper Alternatively, just get a Discord account. | 16:10 | ||
| habere-et-disper | @antononcube Hi antononcube. Do only you see this ? I don't want to spam the channel. | 16:13 | |
| antononcube | Hm... I think the whole channel sees it. | 16:15 | |
| I defiintely see it, though! 🙂 | 16:16 | ||
| Tirifto | Or invite them over to IRC. ;P | 16:18 | |
| antononcube | @Trifto Are you saying that if log in to IRC someone can message me privately. (If yes, then I will do it.) | 16:22 | |
| Tirifto | @antoncube, I think that if you’re connected to the IRC server directly, people can send you a private message (using the command “/msg $nickname $message”). | 16:26 | |
| (And many clients will probably let you start a conversation with a user through the context menu.) | 16:29 | ||
| @antononcube ↑ Sorry, got your name wrong the first time. | 16:30 | ||

| ab5tract | antononcube: 'Hmm.. more precisely "minmax gives a range" ?' ... I believe true precision lies in 'minmax constructs a Range' | 20:01 | |
| And yes, private messaging is a core feature of IRC. That's how we would interact with pirate bots to get into queues for transferring DiVX files | 20:04 | ||
| *DivX | |||
| (IRC also provides several options for initiating direct transfers between users, which is how the bots transferred thoe files) | 20:08 | ||
