Elixir v0.7.2 released
Hot out of the oven! We just released Elixir v0.7.2 with a number of delicious improvements.
One of the most important changes in this minor release is a partial rehaul of the type specification syntax.
Here's the gist:
@spec myfun(integer), do: integer
# becomes
@spec myfun(integer) :: integer
@type a :: fun
# becomes
@type a :: (... -> any) or ((...) -> any) or (fun(...) -> any)
@type a :: fun(do: integer)
# becomes
@type a :: (() -> integer) or (fun() -> integer)
@type a :: fun(integer, do: integer)
# becomes
@type a :: (integer -> integer) or ((integer) -> integer) or (fun(integer) -> integer)
@type a :: fun(integer, integer, do: integer)
# becomes
@type a :: (integer, integer -> integer) or ((integer, integer) -> integer) or (fun(integer, integer) -> integer)
Another change is that Mix now echoes the output of external tools such as git and rebar, and handles exit status correctly. This have previously led to some less-than-perfect workflows.
We've also added a more compact and visual form of the function helper. Now,
instead of function(Enum, :all?, 2) you can use function(Enum.all?/2).
We've also figured out how to achieve an up to 6x performance increase under some circunstances when using records.
...and many other fixes & improvements.
Lastly, but not least importantly, I'd like to mention that we're very excited about how the community around Elixir is building up. Thank you all for being around and supporting us!
