<kevinsjoberg> Why is it breaking upon trying to access the constant at runtime?

@wyhaines

The error is being thrown from the c rystal_sigfault_handler, and my guess right now is that there is some sort of loop that is entered in the compiled code, but not the interpreted code, which is why there is the behavior difference.

I'd be curious to see if it still fails on the current crystal main branch, since at least some of that code has changed a little.

<mfiano> Hello :⁠)

<mfiano> New user here. How long has crystal-lang.org been down?

<jhass[m]> Seems up for me :⁠)

From IRC (bridge bot)

@FromIRC

<mfiano> Odd. It is down for me both at home and at work. Secure connection failed due to PR_END_OF_FILE_ERROR

<jhass[m]> maybe some common "security software"?

From IRC (bridge bot)

@FromIRC

<kevinsjoberg> Up for me as well.

<mfiano> I don't have any such thing, but finally seems to work now and I did nothing.

<mfiano> Sorry for the noise :⁠)

do you have an example of use for iterator of?

From IRC (bridge bot)

@FromIRC

<jhass[m]> The single element overload specifically?

Quinton Miller

@HertzDevil

it seems to happen because you are adding a MacroId to that NamedTuple

this also breaks for example

A = [] of Int32
{% A << "1".id %}
A

Unhandled exception: can't execute `__temp_499[0] = 1` at eval:1:5: `1` has no type (Exception)

I’ve a little question about Int128 how work’s behing that’s use SSE4 or not ?

From IRC (bridge bot)

@FromIRC

<kevinsjoberg> @HertzDevil should it break though?

<kevinsjoberg> Looking at the compiler code, it’s clear MacroId is the culprit, but I still think it should be able to deduce the type here.

@FromIRC

<mfiano> Curious, why does crystal not have traditional block-level symbol table semantics?

:shrug: maybe a better question for the forums?

<terminalpusher> where can I watch the recorded video of the Crystal 1.0 conference?

George Dietrich

@Blacksmoke16

they're not released publicly yet

@FromIRC

<terminalpusher> alright then I will wait for longer

Is there any way to use a module with macro included to include an inner class in a generic class which has an instance variable of the type of that generic class?

That was complicated to write, so here's an example: https://carc.in/#/r/bjqq

George Dietrich

@Blacksmoke16

@RespiteSage https://carc.in/#/r/bjra nice

i feel like what you have should work as i would think it would pick up T from the including type

respitesage

@respitesage:matrix.org

Huh. Yeah, I would also expect it to work.

Ah, so that's the problem in your code. Mine is just a language semantics thing, I guess.

George Dietrich

@Blacksmoke16

are class methods not inherited?

A class inherits all instance variables and all instance and class methods of a superclass, including its constructors (new and initialize).

seems they should

George Dietrich

that doesn't seem right...

duplicate of crystal-lang/crystal#8093 prob

InnerClass must also be a generic

@alexherbo2

how about adding path.match?(pattern) to wrap around File.match?(pattern, path)? https://crystal-lang.org/api/1.0.0/File.html#match?(pattern:String,path:Path%7CString)-class-method

From IRC (bridge bot)

@FromIRC

<mfiano> Hi again. I spent the last couple days reading the language reference and stdlib api docs. I think I could really become comfortable with this as a secondary language.

@alexherbo2

how to get the mime type from a file content?

George Dietrich

@Blacksmoke16

mfiano glad to hear

@alexherbo2 there's a MIME module you can use to get it from the filename/ext

but there isn't a method to do that based on content

From IRC (bridge bot)

@FromIRC

<mfiano> Thanks, it really is nice, and seems to borrow a lot from my primary language, yet seems to check off the items I'm looking for

George Dietrich

@Blacksmoke16

primary lang being Ruby?

Taupiqueur

@alexherbo2

I'm having issues with file without extensions, like bash scripts, using shebangs.

From IRC (bridge bot)

@FromIRC

<mfiano> No, Lisp :⁠)
