<jokke> hey
<jokke> i have a question about macros
<jokke> i have an abstract class that provides a macro
<jokke> this macro then defines a method
<jokke> it seems to me, that the method is defined on the abstract class even though called from a class inheriting from it
<asterite> jokke: doesn't look like that: https://play.crystal-lang.org/#/r/sja
<asterite> If you provide your code maybe it's easier to understand your problem

<asterite> When you create `Bar.new("foo")`, the type of @foo becomes String
<asterite> and String doesn't have a foo method
<jokke> i admit it's very weird doing something like this but i stumbled across this problem writing a serializer
<asterite> Instance variables are inherited, so Foo's @foo gets the type of all subclasses
<jokke> ooh
<jokke> ok
<jokke> that explains it
<jokke> alright, i'll work around it then
<jokke> thanks for clarifying
<jokke> asterite: https://p.jreinert.com/0gSZ/ruby this is what i'm trying to do... :/
<jokke> not sure how i can get past the type inheritance

<jeromegn> sdogruyol: I saw you pulled that in this morning (or yesterday)? :P I was wondering if you'd thought about using blocks (like in Grape) to namespace resources? in that case, before and after could be used without a route argument and apply to the whole block
<sdogruyol> i haven’t thought about that jeromegn
<sdogruyol> you are talking about this right? http://www.sinatrarb.com/contrib/namespace.html
<jeromegn> I guess so :)
<jeromegn> I'm thinking in Grape a lot though
<jeromegn> but yes that would work
<jeromegn> maybe we just need a Grape (Krepe?) on top of Kemal
<jeromegn> :)
<sdogruyol> hahah
<sdogruyol> that’d be pretty sweet

<jokke> jeromegn: sdogruyol maybe you'd be interested in contributing: https://github.com/jreinert/crystal-jsonapi
<jeromegn> that's funny, I'm actually working on an HAL+JSON API at work
<jokke> jeromegn: hehe :)
<jokke> i think a good json api serializer would be very nice to have for crystal. even better of course would be indeed something like grape.
<jeromegn> definitely on my list. it wouldn't need to much work considering something like Kemal exists, it could build on top.
<jokke> yes, exactly
<jeromegn> also, if somebody else wants to do it, that would be nice too haha
<jeromegn> also thinking of making a static site compiler
<jeromegn> there's already Kamber which is close.
<jokke> well, anyhow, as of now my lib already emits spec conform and schema-valid json. Nothing fancy yet, relations are a bit cumbersome to define. I think a lot could be made more convenient with some macro wizardry. So if any of you guys can try out the lib and provide me with feedback or even better, improvements, i'd be very happy :)
<jokke> jeromegn: yeah sign me up for the static site compiler! :) I'd love to see one for crystal!
<BlaXpirit> well i don't see much point in it
<jokke> BlaXpirit: in what?
<BlaXpirit> static site compiler. unless i misunderstand what is mean by this
<BlaXpirit> meant
<jokke> BlaXpirit: something like jekyll
<BlaXpirit> ok, sure, that's it then
<BlaXpirit> there are more than enough of these and crystal has no advantage for them
<jokke> BlaXpirit: i think the crystal community profits from any and all projects written in crystal.
<jeromegn> jokke: I agree.
<jokke> i mean thanks to shards <3 it's super easy to ship your little lib so i end up splitting my projects into manageble portions which in turn may profit someone else doing something similar and that's what i'd expect from any larger crystal project
<jokke> so even if a static site compiler isn't on the top of your wishlist there may be other ways you profit from such a process (some libs that were written in the process)
<jokke> *project
<jeromegn> I love shards, but it needs to be a bit more powerful to be considered serious. I mean... I guess go's package management is also a bit freestyle (resolving dependencies, et al.)

<jokke> hm i just did a benchmark of my lib
<jokke> and i'm a bit confused about the results
Ven has quit [Client Quit]
<jokke> it seems that no matter how many documents i need to serialize its always done with a speed of 16 times per second
<jokke> and 16 times per second isn't that good..
<jokke> (i'm using /dev/null as io for to_json
<jokke> hm now i use a nop io as io (read and write empty method bodies) and there's not a lot of change. (20 times per second)
<jokke> any hints on where to find the bottleneck would be greatly appreciated
<jokke> here's the benchmark code: https://p.jreinert.com/pcGH/
<jokke> i can't believe that the json serializing itself can be so slow
