[elixir-core:6714] [Proposal] Implement String.Chars for Exceptions

Hi all, I was trying to log an exception and noticed that this does not work: Logger.error(exception). Logger could handle this case itself, but I think it would be better to handle it more generically. So, I propose when a module uses the defexception macro, that Elixir automatically define

he method coming from a module import, I would expect it to tell me what import included the method that is causing the conflict. Allen Madsen http://www.allenmadsen.com On Mon, Dec 5, 2016 at 9:25 AM, Ólafur Arason <olafur...@gmail.com> wrote: > I don't have horse in the race, I'm fine

to be a compiler error in Elixir 2.0? If so, does that mean that we would be able to call anonymous functions without the dot? x = fn y -> y + 1 end x(1) # vs x.(1) Allen Madsen http://www.allenmadsen.com On Sat, Dec 3, 2016 at 9:07 AM, Amos King <a...@binarynoggin.com> wrote: > In my experience

Re: [elixir-core:6629] DateTime.from_iso8601 function is missing

As another data point, I've built 5 apps that only use UTC and iso8601 for transport. This feature is much appreciated since it's pretty much the only reason I use Timex. Allen Madsen On Mon, Nov 28, 2016 at 6:20 PM, José Valim <jose.va...@plataformatec.com.br> wrote: > We h

Re: [elixir-core:6377] Re: Deprecate 'single quotes for char lists'

+1 from me. When I teach people Elixir, I skip over char lists. By the time they need to use them, they're typically at the point that they're mentally able to understand them without being overloaded. Allen Madsen http://www.allenmadsen.com On Thu, Sep 22, 2016 at 3:13 PM, José Valim <jose

Re: [elixir-core:6350] Add ｍｉｘ ｒｅｌｅａｓｅ task similar to ｒａｋｅ ｒｅｌｅａｓｅ

I agree with Alexsei that it is pretty standard. If you want to do something off the beaten path, you still have that option with the individual commands available. Allen Madsen http://www.allenmadsen.com On Wed, Sep 21, 2016 at 7:29 AM, Alexsei Matiushkin < aleksei.matiush...@kantox.com>

Re: [elixir-core:6311] modules that are required automatically

Both `import` and `use` will do the require for you. See: http://elixir-lang.org/getting-started/alias-require-and-import.html Until I read this, I also didn't understand why I didn't need to use require everywhere. Allen Madsen http://www.allenmadsen.com On Tue, Sep 13, 2016 at 9:02 AM, Louis

Re: [elixir-core:6258] [proposal] Kernel.fetch_in
