hey there o/
<FromGitter>
<girng> what is forth
<FromGitter>
<girng> hello jokke
<jokke>
any fast parsing libs for crystal?
<jokke>
or maybe there already is something that fits my needs. i want to be able to define scopes for authentication that define access to resources in a pretty granular way.
<jokke>
e.g. something like posts(author: self):comments.readonly
<mps>
girng: forth is programming language made by Chuck More about fourthy years ago and started in control system for telescopes and other fields in astronomy and later in aerospace technology
<mps>
it is only high-level language implemented in silicon directly, afaik

<yb66_gitlab> Hello, I'm looking for some help. I just ran `shards install` for the first time (ever) and got this little beauty: ⏎ ⏎ ``` code paste, see link``` ⏎ ⏎ I'm using the binary install and my libyaml is in /opt/pkg/lib/libyaml-0.2.dylib - anything I should be doing to fix this? [https://gitter.im/crystal-lang/crystal?at=5c64251d80df6804a199edcd]
<FromGitter>
<PlayLights_twitter> Cool, im going to try it this weekend, thanks @j8r
<FromGitter>
<j8r> expect it too be buggy - that's a fun experiment after all :)
<jokke>
anyone?
<FromGitter>
<forkev_twitter> @j8r - crystal-object-send looks pretty sweet, even with it's limitations. very cool.
<FromGitter>
<j8r> thanks :) It's a good example to show how powerful Crystal macros can be.
<FromGitter>
<j8r> Good, I don't know - I won't recommend to use this library other than edge cases like implementing an interpreter
<FromGitter>
<forkev_twitter> I find this valuable not just because of what it can do, but because it's a showcase for the power of macros. with less then 100 lines of code you've set the stage for warping my perspective! i love it.
<FromGitter>
<j8r> haha thanks. You use them @forkev_twitter ?

<r00ster91> from my keyboard. Or do you mean something else?
<FromGitter>
<bew> In your code, the char is not written literally i think, so it's an input you get from somewhere? Maybe you can avoid concerting it to a Char so you already have it in Bytes (for ex)
<FromGitter>
<r00ster91> yes I'm getting it from somewhere. ⏎ I already considered that. I'm getting the data from an array of `Char`s currently. I thought about making it a string maybe since that contains the bytes already so I don't have to convert them to bytes first. But I'm not sure if that will really be faster in my code
<FromGitter>
<forkev_twitter> @j8r - i've not used crystal-object-send yet, just admiring the code and possiblities.
<FromGitter>
<bararchy> Anyone having issues with HTTP::Client on `ubuntu:latest` docker?
<FromGitter>
<j8r> @forkev_twitter i mean you use macros, globally speaking?

<forkev_twitter> Not yet. I've shyd away from them for likely my bias they could introduce a performance or complexity overhead when debugging.
<FromGitter>
<j8r> It may, yes. If you can, better avoiding them.
<FromGitter>
<j8r> That's mainly a compile time penality
<FromGitter>
<Sija> you create a *local* variable inside of `Spec.before_each` block and then try to access it later on, which is obviously not possible
<FromGitter>
<Sija> answering on your (possibly) next question: there's no way to use instance variables in spec too
<devil_tux>
ah.. makes sense
<devil_tux>
why is that tho?
<devil_tux>
and is there alternative?
<FromGitter>
<Sija> in general I'd advise against using `Spec.before/after_each` since they're being run for *every* `it` block
<FromGitter>
<Sija> atm there's no way to scope it
<FromGitter>
<Sija> is there an alternative? that depends on what you want to do
<FromGitter>
<Sija> usually there is ;)
<devil_tux>
sharing the resource/local variable across multiple spec files without using a single spec store for multiple descriptions
<devil_tux>
would fresh variables be of use in that case?
<devil_tux>
i'd rather not define those (i.e. `a`) in multiple spec files
<FromGitter>
<Sija> fresh variables are to be used exclusively within macros
<devil_tux>
:( anything else for above case?
<FromGitter>
<Sija> I guess aside of using some kind of a store (class + @@cvars) you can try local variables defined at the top-level scope
<devil_tux>
ah understood
<devil_tux>
thanks for the help tho @Sija :)

<devil_tux>
btw shall we expect local var scope for specs in the future?
ua has joined #crystal-lang
<FromGitter>
<Sija> nope, that's not how the language works, local variables are you know… local ;)
<FromGitter>
<Sija> but having @ivars support is sth that could work equally well in this case
<FromGitter>
<girng> @mps interesting, ty for info

girng: imho, programmer have to learn at least five (totally) different programming language to have different point of view when solving problems
