module DBConfig
  USERNAME   = "samplename"
  PASSWORD   = "sample123password"
  ADDRESS    = "127.0.0.1"
  PORT       = "3306"
  DBNAME     = "my-db"
  CONNECTION = "mysql://#{USERNAME}:#{PASSWORD}@#{ADDRESS}:#{PORT}/#{DBNAME}"
end

Gives me the error:

No address found for sample123password&#64;127.0.0.1:3310 over TCP &#40;Socket::Error&#41;

Before using password, it worked like a charm.

<watzon> Looks like the @ is being escaped

<Papierkorb> not to mention the missing colon

<watzon> That too

Claudio Holanda

@kazzkiq

Colon?

From IRC (bridge bot)

@FromIRC

<watzon> Between the username and password

Nick Franken

@fridgerator

its in the CONNECTION variable, but not in the error

<watzon> Weird

Anyone here using micrate?

I just tried installing from using brew tap and brew install and I get the dyld: Library not loaded: /usr/local/opt/libevent/lib/libevent-2.0.5.dylib error when running

Claudio Holanda

@kazzkiq

Found the error, my password had an "at" (@), which was conflicting with the syntax from the connection. Even by trying to escape the "@" in the password, the error was still happening.

@kazzkiq

Removing this character solved the problem.

@fridgerator

@jwoertink yes I usually end up having to symlink different libevent in its place

Jeremy Woertink

@jwoertink

I was hoping to just hop in and start cranking stuff out.

@fridgerator

ln -s /usr/local/opt/libevent/lib/libevent-2.1.6.dylib /usr/local/opt/libevent/lib/libevent-2.0.5.dylib

works for me

Jeremy Woertink

@jwoertink

Thanks. I ended up just making a bin/micrate with the API and using it that way. Seems to be working

How can I parse a form with Kemal?

I've read that, thanks. I was actually wondering to do it the kemal way

John Jansen

@johnjansen

kemal is built on top of the stdlib http stuff .. and provides a dsl for routing etc … ill look at the kemal code, but im sure @sdogruyol will defer things like this to the stdlib

@unreadable

nice

John Jansen

@johnjansen

wait, it looks like kemal handles this

params = ctx.request.body
ctx.response.print params["email"]

and got #

I mean params only

not params["email"]

<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)

@FromIRC

<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=
