| thowe | Well, the documentation itself shows a good example of what I mean... The first example shows "$proc.stdout.lines" and then the line is in $_. The second example, "Proc::Async without using a react block:", shows $proc.stdout.tap creating "$v". | 22:23 | |
| How would I do the equiv of creating "$v" with the lines method? | |||
| Might be a moot point as I can't get a react block to actually do anything. | 22:30 | ||
| here's both versions in one snippet: gitlab.com/-/snippets/3728658 | 22:35 | ||
| The problem with tap, is that the lines I am getting from my maillog will be broken up, and so I can't rely on having an actual line to parse. | 22:36 | ||
| My problems with the lines/react method are legion. How do you make your program do anything else other than the react loop? How do you get the line as a variable you name like with tap? Oh, yeah, also, why does it not actually seem to get any data ever... | 22:38 | ||
| tap seems to work until I get a half line, and then the other half of the line as another line. | |||
| I got this from an example in the book "Raku Recipes" but it doesn't really work. | 22:39 | ||
| recipe 2-3 | |||
| I'm sure most of my confusion is just not understanding reactive programs or supplies or whatever, but the question about assigning a variable to lines remains | 22:46 | ||
| I'm really getting lost in the weeds here, though. What I would really like is to know how to get tap to take the lines as they are given and not break them up. | 22:48 | ||
| so, trying to do something where I assemble the lines.. | 23:34 | ||
| ab5tract | When creating a block, you can specify a signature. This allows you to name the parameter and reference it by that name in the block | 23:35 | |
| m: (-> $param { dd :$param })(42) | 23:36 | ||
| camelia | :param(42) | ||
| ab5tract | This works also for if | ||
| m: my %h = :k(‘v’); if %h<k> -> $value { dd :$value } | 23:38 | ||
| camelia | :value("v") | ||
| ab5tract | Or anywhere that a block can fit | 23:39 | |
| The reason the react block doesn’t get any data is because you have to call start on the proc sync object | 23:43 | ||
| You can have this happen in your react block or assign the start promise into a variable before the react block is defined | 23:44 | ||

| thowe | I need more testing but I appear to have a version that can assemble lines as they come in disjointed. | 00:34 | |
| OK. This is the version using tap that can do line reassembly. feel free to tell me how to be more idomatic. gitlab.com/-/snippets/3728669 | 00:41 | ||

| thowe | What's the best way to pass a list as an argument and have it treated as a list of arguments and not one argument? Using an array works, but now I'm curious what the syntax would be to just pass a list object. | 20:34 | |
| I guess just adding ".list" works... nm | 20:39 | ||
| antononcube | @thowe I think you looking for the so called "flattened slurpy." | 21:18 | |
| @thowe ... or the "single argument slurpy." | |||
| thowe | perhaps... | 21:20 | |
| I was passing a command line to Proc::Async.new() | 21:21 | ||
| trying to figure out a few proof of concept things for sort of a bespoke fail2ban replacement gitlab.com/-/snippets/3728669 | 21:34 | ||
| I would want to fire up a bunch of these at the same time... Generate the monitoring/parsing objects from a set of configs. | 21:37 | ||

| ab5tract | m: my @a = [1,2], [3,4], [5,6]; sub s($a, $b) { dd [:run(++$), :$a, :$b] }; for @a -> @ap { s(|@ap) } | 10:17 | |
| camelia | [:run(1), :a(1), :b(2)] [:run(2), :a(3), :b(4)] [:run(3), :a(5), :b(6)] |
||
| ab5tract | thowe: ^^ | ||
| It's a bit more convulated when mixing positional and named argments, however: | 10:22 | ||
| m: my @a = [1,2,:c<a>], [3,4, :c<b>], [5,6, :c<c>]; sub s($a, $b, :$c) { dd [:run(++$), :$a, :$b, :$c] }; for @a -> @ap { s(|@ap[0,1], |%(@ap[2])) } | |||
| camelia | [:run(1), :a(1), :b(2), :c("a")] [:run(2), :a(3), :b(4), :c("b")] [:run(3), :a(5), :b(6), :c("c")] |

| briandouglas_71953 | What editor are most people using for raku? | 21:57 | |
| lizmat | many use commaide.com | 22:00 | |
| briandouglas_71953 | Thanks | 22:07 | |
| antononcube | @briandouglas_71953 Depends for what. I write Raku package with Commaide. But this why to "heavy" and "involved". For simple scripts I use Visual Studio Code with Bscan's Raku extension. For research, I use Jupyter notebooks or chatbooks. | 22:13 | |
| briandouglas_71953 | I'm enjoying writing beautiful code with Raku. I came across this which surprised me, whilst writing a DI container. // Precedence issue with ! and :exists, perhaps you meant :!exists? method set(Str $abstract, Callable $factory) { if ! %!bindings{$abstract}:exists { %!bindings{$abstract} = $factory; } } // WORKS method set(Str $abstract, Callable | 22:22 | |
| $factory) { if %!bindings{$abstract}:!exists { %!bindings{$abstract} = $factory; } } | |||
| Nice error message btw | |||
| antononcube | Consider using LLMs with and for Raku. | 22:33 | |
| briandouglas_71953 | I am, thanks | 22:42 | |
| I'd appreciate a code review as I'm a newbie, pointers are welcome. Here is a DI container, without autowiring. I'll tackle reflection tomorrow. gist.github.com/BrianDouglasIE/0b1...63213cff5e | 23:05 | ||
