ah thanks

either way, in a macro def you have access to @type (Int32) but not self (0) at compile time

Will

@Willamin

Oh well, thanks anyways! :D

What is the LICENSE of the crystal logo?

From IRC (bridge bot)

@FromIRC

<oprypin> @eliasjpr, hey it's not my decision either way. but you're supposed to ask permission. see https://crystal-lang.org/media/ bottom of page

Elias Perez

@eliasjpr

👌🏻👍🏻 thanks

@FromIRC

<oprypin> @jose-rodrigues, see that link too

Elias Perez

@eliasjpr

I think crystal team should open a store for tees and stuff that would be a nice way to contribute for the crystal cause

@FromIRC

<oprypin> for sure

Is Process.run a blocking method?

If I run a cURL command via Proccess.run, and it takes 10 seconds to return, is my application going to hang for 10 seconds?

From IRC (bridge bot)

@FromIRC

<oprypin> @kazzkiq, it's a convenience method that wraps Process.new and Process.wait which blocks the current fiber until the process ends

<oprypin> also why run a curl command......

Hello everyone :smiley: Is there already a binding for WxWidgets for Crystal ? My Google search did not show me suitable result.

Rubi

@codenoid

unfortunately @loloof64 http://crystalshards.xyz/?filter=WxWidgets

Faustino Aguilar

@faustinoaq

huh what does the delegate macro do exactly? Not seen that before

Groogy, check :point_right: http://devdocs.io/crystal/api/0.23.0/object#delegate(*methods,toobject)-macro

Hello everyone :smiley: Is there already a binding for WxWidgets for Crystal ?

unfortunately

But you can try Qt bindings :wink:

Because that's the only way to make Mailgun work with Crystal at the moment

Cris Ward

@crisward

@kazzkiq I have a mailgun client, just not got around to open sourcing it yet. It's actually mailgun and sendgrid. I use HTTP::Client. I want to add a wrapper around SMTP with it to, so it's a common api for however you want to send mail.

laurent bernabé

@loloof64

Thanks @codenoid Maybe I'll have to do myself bindings for the functionnalities I need

Or use another GUI framework like libui : http://crystalshards.xyz/?filter=libui

From IRC (bridge bot)

@FromIRC

<oprypin> @kazzkiq, are you sure about that? crystal's http client should (at least strive to) provide all the same functionality. if it doesnt match that expectation, ask for help / report it

laurent bernabé

@loloof64

Thank you also @faustinoaq Maybe Qt binding will be the solution.

Faustino Aguilar

@faustinoaq

Yeah Qt bindings are awesome! :sparkles:

A = [] of Nil
{% A << 0 %}
{% p A[0] %} # => 0

How is this possible ?

<oprypin> yeah not the first time i see this

@eliasjpr

Maybe is not a bug maybe is a feature :D

@crisward

Just open sourced this - https://github.com/crisward/mailer

@asterite

When you don't use a constant it's not typed, so a constant can be used as a placeholder in macros

That is, when you don't use that constant at runtime

Also known has hack #123 (just kidding)

But Elixir does something similar, only with attributes (which only exist at compile-time, I think)

Kingsley Lewis

@vonKingsley

is there a way to tell crystal to always use some link-flags, so i don't forget to pass --link-flags -I/usr/local/opt/openssl/include --link-flags -L/usr/local/opt/openssl/lib each time

José Rodrigues

@joselfr

@vonKingsley I don't know if you can configure crystal for that but you can do a shell alias. Or better a makefile.

Kingsley Lewis

@vonKingsley

thanks @jose-rodrigues i think ill add it to a shell alias

Claudio Holanda

@kazzkiq

@crisward Awesome! Will take a look at it tonight. Thanks!
