<girng> i love CRYSTAL!
<FromGitter>
<girng> @watzon btw using your json to class website, it rocks!
<FromGitter>
<girng> i was curious. for people running crystal on WSL. how long does it take to load up an app using `crystal src/App.cr`? for me, takes 5 seconds but i remember it used to be faster
<FromGitter>
<girng> is there a custom argument i can send to maybe bypass something to make it go a bit faster?
<FromGitter>
<girng> although, im sure it's prob cuz i'm on WSL. but i mean im noit complaining i just was curious if maybe it could be faster :) 5 seconds is actually quite fast, but i do remember it being faster that's all :P

<FromGitter>
<bew> 123 is a Value type, so it's on stack, and gets copied when assigned

<FromGitter>
<girng> yeah the 123
<FromGitter>
<girng> @bew im doing property equipment = {"Ring" = > 123} in my class. and when a player logs in, i need to basically overwrite all those values to w/e they have saved in my db
<FromGitter>
<girng> so im going to use a hash for this, hope it's ok :)
<FromGitter>
<girng> well, aactually it'll be `property equipment = {} of String => Int32`. then i assign the keys when they choose their character
<FromGitter>
<bararchy> @girng I answered, I hope it makes sense

how did the stream go yesterday ? do we already have a windows version for crystal ? :D

<faustinoaq> Sometimes crystal `require` is a bit confusing, Maybe I miss a bit the explicit Python `import`system π β β Because you don't know where a symbol come from until you compile or search for it in all the project π β β Well, I guess we inherited the Ruby require system, at least my code looks cleaner without a bunch of requires and lines like `import foo, bar from baz` ...
<FromGitter>
<r00ster91> So i'm making a library right now and I would like to use Colorize in it to make the errors a bit more fancy. But then I thought: What if the guy who is using my library already required Colorize? I'm trying to prevent that it's getting required two times because I find that inefficient. So far I tried: β β ```{% if !Colorize %} β require "colorize" β {% end %}``` β β but that doesn't works. You
<FromGitter>
... can't require dynamically... So is there no way? Do I really need to live with this inefficiency? Or is Crystal actually internally not making a second require of the same library? [https://gitter.im/crystal-lang/crystal?at=5ad4a66a15c9b0311401012d]
<FromGitter>
<straight-shoota> There is no inefficiency. Crystal organizes the require paths and will only parse the file once.
<FromGitter>
<straight-shoota> you can add `require "colorize"` in your program as many times as you want.
<FromGitter>
<r00ster91> aah! thats nice. Thanks

<eliasjpr> Thank you @sdogruyol as you can see it was not long ago, fresh memory
<FromGitter>
<sdogruyol> nearly 1 year

<eliasjpr> Without @elorest and @drujensen the project would have not reach the status that is in today. I am proud and happy to be part of the same team and with no further due @faustinoaq @marksiemers @robacarp @fridgerator and new member @jwaldrip π β¨ :shipit:

<sdogruyol> Amber is the biggest OSS Crystal codebase, right @eliasjpr ?
<FromGitter>
<bararchy> is it bigger then the compiler ?

<sdogruyol> probably not

<sdogruyol> I saw @faustinoaq posting something like 30k LOC for Amber

<eliasjpr> > Amber is the biggest OSS Crystal codebase, right @eliasjpr ? β β I cannot make that claim not sure :)
<FromGitter>
<j8r> does the specs can be counted?
<FromGitter>
<sdogruyol> good question
<FromGitter>
<eliasjpr> Honestly if Amber has 30k loc of Crystal code, Im not sure if I can be proud of that, in the sense that we should accomplish the work with less code :) if you know what I mean
<FromGitter>
<eliasjpr> Maybe with Granite and the other shards has that many
<FromGitter>
<straight-shoota> it doesn't
<FromGitter>
<straight-shoota> but 10k is not that much
<FromGitter>
<eliasjpr> yeah 10k is reasonably good number
<FromGitter>
<yxhuvud> The compiler should easily be the biggest crystal project, no?
<FromGitter>
<straight-shoota> probably
<FromGitter>
<straight-shoota> the compiler itself is about 73k loc

<schoening> Hi everyone, I am just playing around a bit while avoiding doing actually programming work :) β I have a question: β Why does the compiler not infer that "data" is Int64 inside the if block? The compiler will complain about JSON::Any type if I just put data * data, but isnt it implied by the if block that it is Int64? β β ``` code paste, see link``` [https://
<FromGitter>
<straight-shoota> `data.raw` is a method call, and the compiler can't know if it will return the same value twice
<oprypin>
schoening, could you tell me, why *would* the compiler infer it? you just called a bunch of methods on some object
<oprypin>
for inference there is exact syntax for it: `if variable.is_a? Type` - here `is_a?` is a compiler construct (.class doesnt work and is a runtime call anyway), and `variable` actually needs to be a local variable, not a method call, because [see what @straight-shoota said]
<FromGitter>
<faustinoaq> > I saw @faustinoaq posting something like 30k LOC for Amber β β @sdogruyol I tweeted that, then I deleted the tweet because it had some typos, I had tweeted an image saying that Amber is 10K of code π β β IMO I think the amount of lines are not relevant here, but the community and the framework organization itself π [https://gitter.im/crystal-lang/crystal?at=5ad4ef6c5d7286b43a35de9a]
<oprypin>
schoening, well it's entirely different, i guess. in this code the compiler doesnt even have any chance to throw any error
<oprypin>
you just made an edit in gitter, people in IRC don't see it
<FromGitter>
<schoening> I did not know that, I only changed the phrasing slightly on my last sentence to be more descriptive: "knowing that the return type is incorrect?"
<oprypin>
oh.. well I guess return annotations are ignored
<oprypin>
until you actually try to use the value
<oprypin>
maybe a bug, maybe not, but not an inconsistency
<FromGitter>
<schoening> The "some_fn_returning_boolean" function infers the type as I would expect. But I do not understand the problem in my test_function with the raw.class comparison. @straight-shoota mentioned that its because it is a method call and it cannot infer if its the same value twice. But then I sort of throw my hands in the air and ask what the point of static typing was if I cant be certain of return value types.
<FromGitter>
<schoening> Doesnt crystals magical compiler go through and checks what the return types of everything is?
<oprypin>
please re-read my initial replies and the documentation
<FromGitter>
<schoening> I don't think I have a problem with the "how-to" but the "why-is-it-the-way-it-is" knowing that I should do is_a instead of == comparison to get something done is great! But I struggle with understanding the underlying differences. is_a looks like a method call to me... Perhaps I am asking in the wrong place here, I dont know..
<oprypin>
schoening, is_a? looks like a method call but is a compiler construct, as described in compiler docs
<oprypin>
actually doesnt sound too reassuring in the docs :/ so i see the confusion
<FromGitter>
<straight-shoota> is_a? also matches subclasses while `==` does not
txdv has quit [Ping timeout: 256 seconds]
<oprypin>
schoening, what the compiler knows: you're calling the `==` method of `(Array(JSON::Any):Class | Bool:Class | Float64:Class | Hash(String, JSON::Any):Class | Int64:Class | Nil:Class | String:Class)`. what the compiler doesn't know: how this `==` method is implemented.
<oprypin>
while in this very specific case it could be made to know, that is intentionally not implemented. instead only constructs documented at /docs/ work
<FromGitter>
<schoening> That makes things a little clearer thanks guys :)

<FromGitter>
<straight-shoota> typeof in javascript/typescript is similar to `#class` in crystal. It returns the *actual* type of a value.
<FromGitter>
<straight-shoota> `typeof` in Crystal on the other hand returns the union of all possible types an expression can return. For this, the expression itself isn't even evaluated.
<FromGitter>
<straight-shoota> simply put, `class` gives you the runtime type, `typeof`the compile time type
