From IRC (bridge bot)

@FromIRC

<postmodern> is there a module or some way of saying "anything that acts like a Hash"

<postmodern> also does crystal seriously not have a StringIO class?

<postmodern> er wait that might be IO::Memory

George Dietrich

@Blacksmoke16

mm dont think so. What are you wanting to do with it?

Enumerable({String, String}) is prob something like what you'd want

there's also String.build

From IRC (bridge bot)

@FromIRC

<postmodern> but will that ensure the given type has a # : String method?

George Dietrich

@Blacksmoke16

it would ensure key/value are both strings, at least when using the methods from that module

From IRC (bridge bot)

@FromIRC

<postmodern> would you be open to me submitting an issue about adding a HashLike (or similarly named) module or abstract class?

From IRC (bridge bot)

@FromIRC

<postmodern> in a module, how would you check if the super was defined before calling super in a method?

<postmodern> in ruby that would be super if defined?(super)

<postmodern> i suspect there must be a macro for checking if a method is defined in the inheritence hierarchy?

George Dietrich

@Blacksmoke16

idt you can without some macro magic

and i doubt that'd idea would fly

From IRC (bridge bot)

@FromIRC

<postmodern> can you define class variables in modules?

George Dietrich

@Blacksmoke16

yes

From IRC (bridge bot)

@FromIRC

<postmodern> such that when the module is extended into a class, it's class variables are defined in the class not the module

George Dietrich

@Blacksmoke16

mm would have to test it

otherwise could maybe make use of like macro extended

From IRC (bridge bot)

@FromIRC

<postmodern> would i have to define the the class variable type inside of a macro extended ?

<postmodern> yeah

<postmodern> ah that works, now i have another error from the specs

From IRC (bridge bot)

@FromIRC

<postmodern> is there a constant for the new-line character/string? "\n" on *nix "\r\n" on windows?

George Dietrich

@Blacksmoke16

dont think so

From IRC (bridge bot)

@FromIRC

<yxhuvud> That'd be nice to have though.

<yxhuvud> might be a mess though. There there still other systems that use "\n\r" ?

From IRC (bridge bot)

@FromIRC

<kevinsjoberg> didn't realize Freenode went ape-shit crazy and banned anyone using IRCCloud. Thank god we moved to Libera.

From IRC (bridge bot)

@FromIRC

<jhass[m]> it's worse, they deleted their entire channel and userdb. It's a new network squatting the old name

@confact

What makes HTTP::Client.get(url).body_io not work when HTTP::Client.get(url).body works? I want to reduce memory somehow, trying to download big files ^^

From IRC (bridge bot)

@FromIRC

<jhass[m]> there's an issue around this somewhere, the interface is just a bit shitty. You want to use the block variant to access body_io, HTTP::Client.get(url) { |response| File.open("dest") {|f| IO.copy(response.body_io, f) } }

Håkan Nylén

@confact

Ah, thanks. Will test it.

Yea, reduced the memory by 60% with that line of code, thanks @jhass[m].

@szabgab

What is the name of the syntax when the condition comes after the statement? (e.g. break if x > 3) in Perl this is called statement modifier, but I don't know how it is called in Crystal

@szabgab

Thanks

<mps> is http gracefull shutdown solved (we talked here about it two years ago, iirc)

<mps> (would be nice to remove 'reference' counting from my http servers)

From IRC (bridge bot)

@FromIRC

<straight-shoota> Not sure what was the status back then, but should be mostly solved

<straight-shoota> When you close an HTTP::Server, it shuts down the accept sockets and no new clients will be received. But existing connections continue to be worked.

From IRC (bridge bot)

@FromIRC

<mps> @straight-shoota: ah, thanks. will test it again

<mps> I missed to read that in changes

From IRC (bridge bot)

@FromIRC

<mps> huh, it still doesn't work

<mps> here is my test code https://tpaste.us/xnWw

didactic-drunk

@didactic-drunk

I think the issue is not with the accept socket but lack of tracking already accepted sockets

From IRC (bridge bot)

@FromIRC

<mps> iiuc the problem is in server.closed?

<mps> uh, no

<mps> I had link how to do this in golang but lost this link

didactic-drunk

@didactic-drunk

close. closes the listening sockets. The main fiber waits for all listening sockets to close then exits. It doesn't wait for fibers handling client connections

So it's "half" graceful

From IRC (bridge bot)

@FromIRC

<mps> maybe I need to add Fiber.yield
