[ruby-core:80111] [Ruby trunk Feature#13137][Rejected] Hash Shorthand
From:
matz@...

ruby-core #80111
Issue #13137 has been updated by Yukihiro Matsumoto.
Status changed from Open to Rejected
Rejected. I saw JavaScript new syntax, but I had no sympathy. It doesn't make anything more understandable.
Matz.
----------------------------------------
Feature #13137: Hash Shorthand
https://bugs.ruby-lang.org/issues/13137#change-63537
* Author: Trevor Smith
* Status: Rejected
* Priority: Normal
* Assignee:
* Target version:
----------------------------------------
The ES6 update to Javascript added object shorthand. I propose that a similar hash shorthand be added to Ruby.
### Before
~~~ ruby
name = 'Matz'
country = 'Japan'
attributes = {
name: name,
country: country
}
~~~
### After
~~~ ruby
name = 'Matz'
country = 'Japan'
attributes = {
name,
country
}
~~~
This would be very useful when building hashes from keyword arguments (especially with default values):
~~~ ruby
def build(name: 'John Doe', age: 100, country: 'Earth', )
attributes = {
name,
age,
country
}
end
~~~
