<FromGitter> <picatz> @jwoertink Not sure if I'm missing something, but: Could you turn that tuple into an array; then zip that tuple with the other array? `, tup.to_a)`
<FromGitter> <jwoertink> oh snap!
<FromGitter> <jwoertink> yup
<FromGitter> <jwoertink> that works. :D
<FromGitter> <jwoertink> Thanks @picatz
<FromGitter> <picatz> Swaggggg biscuits :sparkles:
<FromGitter> <jwoertink> lol
<FromGitter> <picatz> No worries! Glad I could help 'ya out.

<adam12> There was a shard that would generate code from SQL. Does anybody remember the shard name?
<FromGitter> <jwoertink>
<FromGitter> <jwoertink> that one?
<adam12> Bingo. I just found it too
<adam12> thanks
<FromGitter> <icyleaf> Hi, i was trying convert ruby to crystal, and is any method in crystal to get local ip address
<FromGitter> <jwoertink> I don't think so. I saw some open issues about ip address stuff
<FromGitter> <icyleaf> ```Socket.getifaddrs```
<FromGitter> <picatz> @icyleaf I'm not sure of any way to do this without shelling out to `ifconfig` under the hood at the moment :(
<FromGitter> <icyleaf> thanks @picatz @jwoertink

<FromGitter> <schoening> Ups..
<FromGitter> <schoening> Thx phone.
<FromGitter> <schoening> Is crystals parallelism gonna allow for read access across "threads" ?
<RX14> yes
<RX14> we won't get rid of shared memory between fibers
<RX14> just like go
<FromGitter> <phoffer> RX14 Hi it’s in hibernation, if there is interest I’ll start working on it again
<RX14> @phoffer I'm seeing interest, but I was almost positive I saw an up-to-date shard...
<RX14> Maybe i'm dreaming
<FromGitter> <phoffer> I’ll look into whether there are regressions with the latest version of Crystal and update if I need
<RX14> i'm sure there will be a breaking change after almost a year LOL
<RX14> crystal just works that way...
<FromGitter> <phoffer> Haha yeah but there’s honestly not a whole lot of code to make it work. It’s mostly just the trial and error of getting it working in the first place, and having some organization to it
<FromGitter> <phoffer> Oh yikes if Piotr is interested then :) :) I’m a big fan of his work
mark_661 has quit [Remote host closed the connection]
<FromGitter> <phoffer> But I think the use case he explained would be a good one to experiment with, the overhead for going to Crystal and back is pretty low for primitive types

<FromGitter> <jwoertink> If I have a YAML file with an array of hashes in it where each hash matches with a YAML mapping, is there a way to do something like Blah.from_yaml, and retun an array of Blah?
<FromGitter> <jwoertink> or do I just have to YAML.parse, then map each hash back to_yaml, then Blah.from_yaml on those individually?

<FromGitter> <jwoertink> ```struct Sample ⏎ DATA = {% YAML.parse("data.yml")) %} ⏎ end``` []
<FromGitter> <jwoertink> `undefined macro method 'TypeNode#read'`
<FromGitter> <jwoertink> Is doing this not a good idea?
<FromGitter> <jwoertink> or, is there another way of doing this? I figured it would be better to just read and parse the yaml file once instead of doing it each time I instantiate the struct
<FromGitter> <jwoertink> or maybe this is just a bug
<FromGitter> <jwoertink> I guess I can do it without the macro. I'm not really sure if there's any gain either way
<BlaXpirit> jwoertink, you cannot execute arbitrary Crystal code in macro language, it's an entirely different language
<BlaXpirit> (which is a shame)
<FromGitter> <jwoertink> ah, ok.
<FromGitter> <jwoertink> thanks
<BlaXpirit> jwoertink, you could do like but it's usually not worth it
<FromGitter> <jwoertink> lol
<FromGitter> <jwoertink> That's cool though that you can do that
<FromGitter> <elorest> @jwoertink You can compile and execute a crystal file within a macro and return from it. This is really useful for returning or building code dynamically within a macro.
<FromGitter> <jwoertink> Awesome
<FromGitter> <elorest> I usually take that approach. Similar to that link above.
<FromGitter> <jwoertink> Any suggestions for my previous question about the array in a yaml file?
<FromGitter> <jwoertink> if I have a yaml mapping like `YAML.mapping(name: {type: String})`, and an array like `- name: A\n- name: B`. Is there any handy methods like doing `SomeClass.from_yaml` but where it returns an array of SomeClass?
<FromGitter> <jwoertink> right now I parse the yaml, then map each hash in the array back to yml then call the from_yaml
<FromGitter> <elorest> Sorry I’m in a call but I have a solution.
<FromGitter> <jwoertink> no worries

<FromGitter> <jwoertink> Not quite what I'm looking for, but that gives me a few ideas to try!
<FromGitter> <jwoertink> thanks :D
<jhass> with json you can just Array(Something).from_json, try if it works with from_yaml too?
InternetFriend has joined #crystal-lang
<FromGitter> <jwoertink> nice!
<FromGitter> <jwoertink> Yup, that works exactly how I wanted it to
<FromGitter> <jwoertink> Thanks @jhass

<FromGitter> <elorest> I guess I miss understood what you were trying to do.
<FromGitter> <jwoertink> no worries. I'm horrible at explaining things. They always make sense in my head, and then come out as gibberish
<jhass> otoh isn't programming all about deciphering the gibberish other people produce and then translating that into gibberish for machines? :P
<FromGitter> <jwoertink> lol

<FromGitter> <elorest> Copying errors into google and clicking on stackoverflow.
<jhass> good programmers know the accepted answer isn't always the best one for their usecase and scroll down!
<jhass> the industries mystery though: where do those stackoverflow people copy their answers from?
<FromGitter> <elorest> good programmers feel a little bit guilty about getting all of their answers from a site written in c#
<jhass> hehe
<Papierkorb> jhass: Don't! You're about to crash the matrix
<jhass> didn't know it's C#, always looked railsy to me
<FromGitter> <elorest>
<FromGitter> <sdogruyol> lol
<FromGitter> <sdogruyol> yeah SO is a great example of C# done right
<FromGitter> <elorest> Yeah.
<FromGitter> <picatz> C# done right is a tough pill for me to swallow :P
<FromGitter> <sdogruyol> haha
<FromGitter> <picatz> ( though I totally understand, and pretty much agree )
<FromGitter> <sdogruyol> it's a good language
<FromGitter> <sdogruyol> and they have deep pockets :/
<FromGitter> <picatz> *Sounds subjective to meh.* :P
<BlaXpirit> what exactly is wrong with C# though?
<FromGitter> <sdogruyol> not much, just the community i guess
<BlaXpirit> i was against it for the longest time but it's actually pretty good
<FromGitter> <picatz> *HEATHENS*
<FromGitter> <sdogruyol> lol
<FromGitter> <sdogruyol> you can't den its' adoption
<FromGitter> <picatz> Communities drive the language for the most part tho ami right?
<FromGitter> <sdogruyol> deny*
<FromGitter> <sdogruyol> @picatz not if it's funded by big companies like google, msft e.g
<FromGitter> <sdogruyol> oh no need to mention java :D
<BlaXpirit> what's this msFT that i keep seeing
<FromGitter> <sdogruyol> they dont give a damn about the community
<FromGitter> <picatz> Well, those *are* the communities, right? Like, those companies are part of the community.
<BlaXpirit> oh what do you know, Microsoft Corporation NASDAQ: MSFT
<FromGitter> <sdogruyol> well, i dont count them as 'community'
<FromGitter> <sdogruyol> they are not organic and mostly acting with some market profit share bullshit
<FromGitter> <picatz> Fair enough. I sort'of do.
<FromGitter> <sdogruyol> it's ok
<FromGitter> <sdogruyol> :)
<FromGitter> <picatz> Without them, do you think there would be a community around C#?
<FromGitter> <picatz> Well, probably would be. I guess, I'm assuming, the community wouldn't be the same.
<FromGitter> <picatz> Which totally goes without saying. Because I like stating the obvious.
<FromGitter> <sdogruyol> well there's mono
<FromGitter> <sdogruyol> they did a fantastic job and now they're being the official linker stuff for .net core
<FromGitter> <sdogruyol> should have been from the start though but companies
<FromGitter> <picatz> TIL what mono is.
<FromGitter> <sdogruyol> :D
<FromGitter> <picatz> :+1: I appreciate you.
<jhass> BlaXpirit: lookup todays :D
<FromGitter> <sdogruyol> @picatz thank you
<FromGitter> <picatz> NONONOnonooonononon. no. thank. you. :clap:

<FromGitter> <jwoertink> Ok, so `YAML.mapping` creates an `initialize(pull : YAML::PullParser)`. Is there a way to access that `pull` object within that class?
<FromGitter> <jwoertink> It looks like that `pull` object responds to `to_json` and `from_json`, and I would like to delegate those methods to that object
<jhass> no, it's gone and stateful anyway
<jhass> where did you see its to/from_json methods anyway?
<jhass> it's probably just Object#to_json etc
<FromGitter> <jwoertink> well, I guess it's inheritied from Object
<FromGitter> <jwoertink> yeah
<jhass> those are of no use without a initialize(JSON::PullParser) / to_json(JSON::Builder) anyway ;)
<FromGitter> <jwoertink> I'll just switch from YAML.mapping to JSON.mapping.
<FromGitter> <jwoertink> Has anyone benchmarked those two to see which one has better parsing performance?
<jhass> I wouldn't be surprised if JSON is faster
<FromGitter> <picatz> Nope. But, I'd love to see one :+1:
<FromGitter> <jwoertink> I'm sure with small files it's probably not much different, but I'm thinking about if you're constantly loading in config files, or just really large files
<jhass> since it's simpler to parse than JSON and also from what I've heard libyaml isn't the fastest thing in the world either while Crystal's JSON parser is actually pretty good
<FromGitter> <jwoertink> so probably a benefit moving all these config files to json then ;)
<jhass> eh I don't think that'S anywhere near a size where it would matter
<FromGitter> <picatz> *Benchmarks. Benchmarks. Benchmarks.*
<jhass> uh, of course I meant since it's not simpler to parse than JSON
<jhass> do one, require "benchmark/ips" and go
<FromGitter> <jwoertink> I'll try it out just for fun and see what I get
<FromGitter> <picatz> Lemme know how it goes.
<FromGitter> <jwoertink> will do! I'm going to use actual data that I have for more of a real test
<FromGitter> <picatz> I'd assume, for a comprehensive test, you'd need to try a larger sampling of data.
<FromGitter> <picatz> I'm actually terribly curious to know when the "right" time to use YAML would be and the "right" time to use JSON. I guess, for speed in this case specifically. For your use case though, I definitely get jus using your current data though.
<FromGitter> <picatz> MABYE I'LL ATTEMPT TO EXPAND UPON YOUR WORK. '\( ' ~')/'
<FromGitter> <jwoertink> TIL: calling `to_json` on a rails model converts the enum. calling `to_yaml` doesn't
<FromGitter> <jwoertink> ```code paste, see link``` []
<FromGitter> <jwoertink> ok, there's your answer
<FromGitter> <jwoertink> each file is a little over 4mb with 500 records each
<FromGitter> <jwoertink> about 50 mappings in each which are `String?` `Int32?` `Bool?` or `Time?`
<FromGitter> <jwoertink> oh, and one `Hash(String, String?)?`
<FromGitter> <picatz> Well.
<FromGitter> <picatz> I'mma just accept that as my answer.
<FromGitter> <jwoertink> I should also say that, this is how I benchmarked
<FromGitter> <jwoertink> ```code paste, see link``` []
<FromGitter> <picatz> :+1: Very interesting.
<FromGitter> <picatz> I guess I didn't think yaml would be *that much* slower.
<FromGitter> <jwoertink> lol. I didn't either. I was thinking it would say like 2x slower or something
<FromGitter> <picatz> Pretty neat stuff.
<FromGitter> <picatz> Like, mind opening mannnnn.
<FromGitter> <picatz> *tiny splosions in ma brain homie*
<FromGitter> <jwoertink> lol
<FromGitter> <picatz> Today we learned just always use json.
<FromGitter> <picatz> *Because that's how this works. Def how this works.*
<jhass> uh, take the read out of the benchmark
<jhass> disk IO is anything but consistent :P
<FromGitter> <picatz> That's a good point.
<FromGitter> <picatz> *Don't argue with our science.*
<jhass> :P
<FromGitter> <jwoertink> ok, 1 sec
<jhass> nonetheless while it's that much slower I'd rather say json is that much faster ;) 200ms for 4M isn't too bad
<FromGitter> <jwoertink> ok, updated
<FromGitter> <jwoertink> ```code paste, see link``` []
<FromGitter> <jwoertink> ```code paste, see link``` []
<FromGitter> <picatz> THAT IS SOME SCIENCE.
<FromGitter> <picatz> TO ME
<jhass> hah you got some good disk cache there :D
<jhass> would've expected more overhead from the FD opening/closing alone
<FromGitter> <picatz> tbh I dunno how that stuff works
<FromGitter> <picatz> *hence* SCIENCE TO ME :D

<FromGitter> <drosehn> Is there an EDN formatter written for crystal yet?
<FromGitter> <clthck> is there rails-like framework written in crystal that is mature enough as rails?
<BlaXpirit> srsly?
<FromGitter> <fridgerator> mature as rails?
<FromGitter> <jwoertink> lol
<FromGitter> <jwoertink> I've been in development for 35 years and I'm still not "mature"
<FromGitter> <fridgerator> @clthck there are some frameworks, but the language isnt even as old as the rails framework, you can check here:
<FromGitter> <fridgerator> Kemal being the most popular, but its more like sinatra
<FromGitter> <jwoertink> Do you guys rememebr when the New York public library posted that rails job that required 10+ years rails experience? And then DHH was like "I can't wait until I qualify for that job"

<FromGitter> <jwoertink> Dec 31st
<FromGitter> <jwoertink> The best thing to help move that quicker though is to build projects with it
<FromGitter> <spalladino> @jwoertink hopefully we won't have to be working on new year's eve and will have a stable version ready earlier :P
<Papierkorb> KCreate, it's great for some. I like it, but I liked Roda+Sequel better. If you didn't yet, give it a try and build something simple
<FromGitter> <jwoertink> the more people doing that, the better chances we have of catching bugs
