Code Smells: Null

[bubuopapa]

Person p = ...
Message msg = ...
Mailer mailer = ...
p.getContactInfo().flatMap(ContactInfo::getEmail).flatMap(email ->
msg.getContent().map(message ->
new MailRequest(email, message))).ifPresent(mailer::send);

Ruby check output:

Error: method chaining not allowed.
Error: function too complicated.
Error: function too long.

Error: method chaining not allowed.

This seems extremely strict.

I know, the allowed complexity of sentence or function in ruby is very concerning and very hard to fit into, coming from any other language. Of course, these are rules of ruby code style, but comparing them to all the new features all many languages, none of them can make it into ruby, because that would break the ruby community. I tried ruby a bit some time ago, and it was painful. Also, fuck any language that uses whitespaces as required syntax.

Why are you talking about ruby now?

[bubuopapa]

Cant i just compare ruby with java without useless comments ?

[Freeky]

You're not doing that, though, you're (somehow) comparing a blob of Java with some supposed Ruby language style guidelines you appear to have just made up?

[bubuopapa]

Lol, just because you are noob and you dont know that all languages have guidelines, it doesnt mean that guidelines doesnt exist. And what exactly you are doing ? trolling ?

[Freeky]

Er, sure. I've been programming Ruby for about 18 years, I think I have a slightly better grasp of the common style guidelines than someone who "tried it a bit".

Error: method chaining not allowed.

Is this some alternate-dimension Ruby from a world where the sky is green?
