Structo (structo v0.1.3)

JavaScript-style object constructors.

This library allows you to construct maps and structs like this:

~m{a, b, c: d}

Instead of:

%{a: a, b: b, c: d}

And it works in matches too:

iex> ~m{a, b: 2} = %{a: 1, b: 2}
iex> a
1

Summary

This sigil acts as a shorthand for constructing maps with JavaScript-like syntax.

(macro)

This sigil acts as a shorthand for constructing maps with JavaScript-like syntax.

iex> import Structo
iex> a = 1; b = 2; d = 3
iex> ~m{a, b, c: d}
%{a: 1, b: 2, c: 3}

This library can construct standard Elixir structs too:

iex> import Structo
iex> alias Hello.MyStruct
iex> a = 1
iex> ~m{:MyStruct, a, b: 2}
%Hello.MyStruct{a: 1, b: 2}

This syntax is preferred over the deprecated use Structo behaviour, which will be removed in the next release.
