<RX14> if you want something to do what the OS does, write an OS

<brycek> ain't my first rodeo, i've done embedded and other no-os stuff before, just wondering if anyone else had with crystal or if it'd be a lot of new work/resarch/etc.

<brycek> ooh fancy

@FromIRC

<RX14> brycek, oh sorry, i thought you were the same guy from yesterday so I didn't explain much at all

<brycek> ah

<RX14> the hard part of starting crystal with no stdlib is that you need to placacte the compiler

<RX14> the crystal compiler is hugely related to the current stdlib

<RX14> there's no official API

<RX14> the compiler just constructs calls to things which it expects to exist

<RX14> because we have quite a bit of syntax sugar

<RX14> unfortunately when writing a crystal OS you need to deal with that and work out which methods you need to stub out

<RX14> so while Nuumite is an x86 OS, it will likely be a really good resource because much of it isn't architecture specific, it's crystal specific

There's also this: https://github.com/lbguilherme/os-crystal

There was another project, can't remmber the name

does kemal support template engines?

<watzon> You can also create a custom middleware if you want to use an engine other than ECR http://kemalcr.com/docs/middlewares/

How the heck am I suppose to connect to MySQL with password?

Nick Franken

@fridgerator

mysql://user:password@host:port/database_name

Claudio Holanda

@kazzkiq

tried that. failed miserably

Nick Franken

@fridgerator

well thats how you do it

does your password have special characters?

Claudio Holanda

@kazzkiq

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.

@FromIRC

<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

@FromIRC

<watzon> Weird

<watzon> Upload your code as a gist or something

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.

Jeremy Woertink

@jwoertink

using the latest crystal

Claudio Holanda

@kazzkiq

Removing this character solved the problem.

  crystal run src/app.cr
Error in src/app.cr:3: while requiring "kemal-session-redis": can't find file 'kemal-session-redis' relative to '/home/alex/Projects/Crystal/app/src'

I've installed the dependency

Nick Franken

@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.

Nick Franken

@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
