Which program language would most excite you to want to contribute to an open-source project, all else being equal?

I find some #software #programming guidelines for source code to conflict.

For instance, in the #java programming language, a tennet exists that claims that a method having more than 5 arguments is difficult to test. It's advised to replace those arguments with a single object.

But that seems to conflict with the clean code tennet that states that a procedure's input must be explicit in its signature. An arguments object is not explicit about its members.

Thoughts?

In the #java #programming #language, declarative predicates are available in standard objects like Optional:

Optional.of(name).ifPresentOrElse(
content -> actOnName,
() -> warnOnMissingName
);

In #rustlang, they are available in standard objects like Option:

match name {
Some(ref content) => act(content)
None => warn("no content")
}

In #dark these probably don't exist, as it favors guard clauses.

Half of this is #PMD failing to recognize that EMPTY and empty() differ: it thinks they are the same.

Another half of it is data flow anomalies: declaring variables outside of the scopes in which they get used. In #java this is quite a normal coding behavior.

And then there's the admonishment that we shouldn't be catching a #NullPointerException. Well, guess what? The code that throws it is not mine, and my code needs to deal with their errors.

I've fallen to littering my code base with exceptions to stupid warnings and #java coding to avoid warnings on those warnings. Grrr.

In #java #software #programs it is the #PMD #SuppressWarnings statement that will indicate what version of PMD was run (it's a static code analyzer for quality control), and how annoying the developer found it.

Dear #java #programming #language designers,

You know what would be great?

Overriding a central enum to add locally required values.

Use case: an HTTP client's mime types. The client has a preset enum for mime types. My application needs a different mime type. Java won't let me add my own because enums become final static singletons.

One could argue using an enum here was a bad choice. Extensibility should have been expected.

I argue that the bad choice was making enums final.

Looking for someone who works with #Java? Well I know a lot about the bird -- contact me.

@danielhglus Yep, I would dislike that, too. It's no better than the amount of mind-numbing boilerplate coding #java requires from us.

And that affects my InternalWarning and InternalError implementations. because they implement ICommunication.

Could I move the override into a different interface. Yes. I can. Only to once more lose the up-cast from new interface to Communication.

Could I solve it by applying #generics. Yes. I can. Only to introduce an amount of #complexity that does not relate to the issue at hand.

Thanks. #java. - 2/2

And in my one application I can create a new Communication instance adding all the info from the old one. switching in the new response code.
But in the other. #java won't let me do that. Because there. creating a new Communication requires a SignedRequest. but the old Communication exposes an IRequest. An up-cast would solve this. But the #programming #language won't allow that.

Instead we get to ask ICommunication to perform the switch of the response code - 1/2
