shred_alert joined
|
|||
| zln | ah, I began learning perl. Maybe I should go on and begin learning Perl 6 instead ? | 09:11 | |
| is it like c & c++? | |||
| the difference I mean | |||
|
09:17
mahmudov joined
|
|||
| shred_alert | zln, Perl 6 is called Raku now. :) | 09:17 | |
| zln | :-D | ||
| shred_alert | You can write Raku code that looks a lot like C(++) | 09:18 | |
| That one of the great things about it. It's flexible enough to fit around many styles and paradigms of coding. | |||
|
09:18

| epony | there is no difference, there is familiarity | 09:18 | |

|
|||
| epony | en.wikipedia.org/wiki/Raku_(progra..._language) "Raku is a member of the Perl family of programming languages". | 09:21 | |
| zln | Should a person like me who began to learn perl switch to raku instead or keep going | 09:23 | |
| epony | how old are you? | 09:24 | |
| shred_alert | What do you want to do with the programming language? | ||
| zln | eh, I am 29. Donno, maybe mostly sysadmin things and other data manipulation things. | 09:26 | |
| epony | keep going | ||
| zln | In what situation should I not keep going? :) | ||
| shred_alert | You won't lose out by switching to Raku in that case. | 09:27 | |
| Unless you already have dependencies with Perl modules, I'd recommend learning Raku instead. | 09:28 | ||
| zln | No I am not a maintainer or pro-programmer | ||
| It's just for enthusiasm only :) | |||
| shred_alert | In that case, Raku is a great choice! | 09:29 | |
| zln | Is it as integrated as perl when it comes to sysadmin and data manipulation? | 09:30 | |
| shred_alert | No. It's still a new language in the sysadmin world. | ||
| zln | And. What books would you recommend for learning Raku deeply and thorougly | 09:31 | |
| shred_alert | Uh. I'd just recommend learning Raku by looking up a basic syntax guide and building something. You'll get started a lot faster that way. | ||
| You can refer to docs and books when you want more depth | |||
| And share your code as well to get pointers | |||
| zln | Alright | 09:32 | |
| I think we got it covered :) | |||
| shred_alert | (y) | ||
| zln | Thanks for taking time | ||
| shred_alert | You're welcome. :) | ||
| zln | :-= | ||
| :-) :p | |||
| shred_alert | zln, this link is very useful: docs.perl6.org/language/syntax | 09:35 | |
| zln | Will do, thanks :) | 09:36 | |
| shred_alert | Anyone know why there are two versions still floating around? docs.raku.org/language/syntax docs.perl6.org/language/syntax | 09:37 | |
| sena_kun | shred_alert, for backward compatibility for some time? | 09:40 | |
| yesh, redirects, but | |||
| shred_alert | Ah okay | 09:48 | |
| Was just curious | |||

| sarna | does raku have something like python’s virtualenv? | 09:54 | |
|
09:55
sena_kun left
10:05
shred_alert joined
|
|||
| zln | what is python's virtualenv maybe you could explein if there who have the answer on the raku side but cannot relate to python | 10:18 | |
| I think maybe | |||
| shred_alert | Basically you're decoupling the environment that your programming is running in from the base operating system. | 10:20 | |
| Altai-man_ | there is p6env, but not sure how "local" can it be | 10:21 | |
| also I think rakudobrew can do things | 10:22 | ||
| shred_alert | If you really want to decouple an app from the base system you can look into stuff like VMs, containers, and jails. | 10:23 | |
|
10:24
hacktor joined
|
|||
| sarna | yeah, but vms containers and jails are really heavyweight.. using them when I just want to have two different versions of libraries installed for two different projects would be.. suboptimal | 10:26 | |
| or at least that’s my viewpoint | |||
| shred_alert | Just listing options :) | 10:27 | |
|
10:28
patrickb joined
|
|||
| Altai-man_ | sarna, two versions of raku libraries? you can do that without any venvs. :) | 10:30 | |
| just specify :ver<foo> and :ver<bar> in META6.json to install both, and then you can use Cool::Lib:ver<foo> and use Cool::Lib:ver<bar> and both will be available in this scope. | 10:31 | ||
| and if they are in a different projects, then no problem at all | 10:35 | ||
| sarna | Altai-man_: oh wow that’s cool | 10:37 | |

| Kaiepi | i'm writing a routine that takes another routine along with a capture of arguments and using that routine's signature, maps its parameters to corresponding values in the capture. the problem is atm i keep state for which named params have been seen and where in the list of positional params the routine is currently at because of slurpy parameters, but this is really annoying to write in such a way that it's | 15:17 | |
| both testable and optimal. are there other ways to go about implementing this? | |||
| tellable6 | 2019-12-26T18:52:37Z #raku <jmerelo> Kaiepi OK :-) | ||
| Kaiepi | in js i'd use something like a generator for something like this, which is similar to gather, but i want to be able to test how individual params get mapped, which i'm not sure if i can do with that | 15:19 | |
| oh, looks like the Iterator class does what i'm looking for | 15:32 | ||
