Just a simple form

<Papierkorb> ... I got the compiler to compile args = [ ] and then throw an runtime exception

<Papierkorb> That's a new creative one

unreadable

@unreadable

It has to be args = [] of type

From IRC (bridge bot)

@FromIRC

<Papierkorb> Sure. The point is that that shouldn't even compile in the first place.

Huston, we have a problem..

From IRC (bridge bot)

@FromIRC

<Papierkorb> struct Foo; YAML.mapping(bar: String?); end; Foo.from_yaml(%<bar: "# I'm not a comment">) Kaboom.

<Papierkorb> Union(String | Nil).from_yaml will pull the "next thing" (#read_raw), and then call String.from_yaml(that_thing), which now redoes the cycle and expects a YAML document. And now that_thing suddenly becomes a true comment.

<Papierkorb> (yadda use nilable)

<hightower2> Hey Papierkorb I just got an idea how I'm going to support calling <parent>.new_listener.emit( <signal>.name) when a signal is installed in Cute

<hightower2> I am going to simply open the Cute::Signal class and add the property :⁠parent

<hightower2> Then in the parent class, when I list all its signals in an array anyway, I'll just go over those signals and set their #parent=

<hightower2> This will be just fine and won't require me to modify the 'macro signal' or anything inside Cute

<hightower2> Yet the signals will know their parent, and inside on() they will be able to do super; parent.new_listener.emit....

how can I convert IO type to String?

Ghost

@ghost~55586c4815522ed4b3e08557

you can read from the IO

unreadable

@unreadable

Yeah, that's good too

How can I/

I tried with a slice but gave me an error

I'm mainly looking to read the request body of a form

Ghost

@ghost~55586c4815522ed4b3e08557

you're probably looking for IO#gets_to_end to read the whole IO to a String

What kind of sort does Array#sort uses ?

From IRC (bridge bot)

@FromIRC

<Yxhuvud> @bararchy: I can recommend diving into the source for that kind of questions. The source is quite readable.

Ghost

@ghost~55586c4815522ed4b3e08557

iirc it's a really fast sorting algorithm, faster than the one in C++ stdlib

Bar Hofesh

@bararchy

Ok, it seems to use quick sort

Oh, also heap sort

Ghost

@ghost~55586c4815522ed4b3e08557

here is the pr: crystal-lang/crystal#3514

it's intro sort, never heard of it though..

Bar Hofesh

@bararchy

Cool

I'll read on it on wikipedia sounds interesting

@unreadable

Finally I got it. I was using ctx.reques.body instead of ctx.params.body with kemal

How do I use libui.cr?

I want to run the samples, but I have no idea how :(
