I'd guessCrypto already exists and is nodoc

@didactic-drunk

I don't see defined Cryptoanywhere. It's implicitly defined as Crypto::{Subtle,Bcrypt,Blowfish}

@didactic-drunk: because Crypto is marked as originating from stdlib by its first occurrence in the whole code blob, and the whole stdlib is excluded from doc building

@didactic-drunk

@oprypin:matrix.org Now I have a workaround. Thank you

@didactic-drunk: do you wnat me to move ioctl.cr to crystal-posix? if so, could you look over the code first.

didactic-drunk

@didactic-drunk

@postmodern:matrix.org You're welcome to move it now, or not. I'll have to look in a few hours but that can be handled with PR's.

How do I check if a module exists in a macro?

Kaia Leahy

@tenebrousedge

why?

usually if I am wondering about questions of that nature, I'm checking if an object subclasses a type, or whether it responds to a given method

didactic-drunk

@didactic-drunk

I have an optional module which may not exist if not required

Jonathan Silverman

@mixflame

there is a definite bug in resolving localhost sometimes in crystal on my OS

resulting in my crystal app starting sometimes in crashed states

@nolyoi

I'm trying to install crystal from source and getting a You need to have a crystal executable in your path! or set CRYSTAL env variable. I've tried CRYSTAL="$HOME/crystal/bin/crystal" and
export PATH="$HOME/crystal/bin/crystal:$PATH". Anyone know what I'm missing here?

Ali Naqvi

@naqvis

you need to have previous version of Crystal to compile newer version

Nolan Mayersky

@nolyoi

theres no way to build from source for unsupported linux distros?

figured it out. had to download the tarball and use that crystal binary to run make in the source

there's https://github.com/crystal-lang/bootstrap-script if you wouldn't trust that approach, but probably needs some patching up by now (and a lot of patience)

Rishav Sharan

@rishavs

is there a way to add new data to HTTP::Server::Context? I want to pass some connection specific data between middlewares

If it's primitive data you could modify the request/response headers perhaps

See crystal-lang/crystal#3863 for some existing discussion around this

Does anyone know of any native file browsers in crystal?

@watzon: I remember you were working on crypto libraries for crystal. Ever heard of libnettle and libhogweed? Just noticed them today doing a system update.

ah interesting, you define the syscalls first instead of passing arguments to syscall(2)

Ary Borenszweig

@asterite

Whats the benefit of syscall? Can we avoid using it? It's bad for something I'm working on

Actually, nevermind

Alex Kampa

@alex-kampa

I'm trying to figure out the simplest way to listen on 2 separate tcp ports, is this going to work:

spawn do
  while client = server1.accept?
    spawn process1(client)
  end
end

spawn do
  while client = server2.accept?
    spawn process2(client)
  end
end

Ali Naqvi

@naqvis

Crystal without preview_mt is single threaded, so as long as you call server1.listen it will block the main thread and code below will never get a chance to execute

George Dietrich

@Blacksmoke16

use nginx to listen and forward to the crystal app :P

Ali Naqvi

@naqvis

either you go with parallelism (i.e. via -Dmt_preview) or better go with two separate process each listening on its own port

or better as @Blacksmoke16 suggested, better to with some battle tested servers as proxy in-front
