iterable.stringPrefix still exist???

[ShapelessCat]

The stringPrefix method is mentioned in this page: https://docs.scala-lang.org/overviews/collections-2.13/trait-iterable.html
However, when I open a specific API page like Iterable, I can't find this method. Also in the REPL, I can't invoke this method.

A related issue, when I search "stringPrefix" I can see it in the searching result page of API Doc, but when I open a specific trait/class API page, I can't find it.

I think a pull request simply removing the reference to stringPrefix from that page would be accepted. the method exists, as does its sibling className, but they are declared protected[this], which is why you can't call them from the REPL. see https://github.com/scala/scala/blob/2.13.x/src/library/scala/collection/Iterable.scala#L67-L68

afaics, these methods are only of interest to collections implementers, not collections users.

However, when I open a specific API page like Iterable, I can't find this method

that seems like a bug in the Scaladoc tool — if the method isn't shown on the page, because it is inaccessible except to implementers, it shouldn't be included in search results, either. a bug report on that over at https://github.com/scala/bug would be welcome (if one doesn't already exist, that is!)

Here is the previous link: https://scala-lang.org/files/archive/api/2.13.0/scala/collection/Iterable.html#stringPrefix:String

API consumed by implementers ought to be in the doc scaladoc.

I know there is an issue to restore an "access" option to scaladoc, so you can pick whether to show only public or also private elements.

scala> new Iterable[Int] { def iterator = Iterator.empty[Int]}
res1: Iterable[Int] = Iterable()

scala> new Iterable[Int] { def iterator = Iterator.empty[Int] ; override def stringPrefix = "Empty" }
                                                                             ^
       warning: overriding method stringPrefix in trait Iterable is deprecated (since 2.13.0): Override className instead
res2: Iterable[Int] = Empty()

I guess they fiddled with it.

API consumed by implementers ought to be in the doc

but the place for it is https://docs.scala-lang.org/overviews/core/custom-collections.html IMO

UPDATE: oh, I see now, you were referring to the Scaladoc (as per scala/bug#10999). so that's separate

[som-snytt]

You're right, the overview should be tuned. I'll fix my comment to say scaladoc [sic]. In Java, the API is the javadoc and the wordy stuff is a tutorial.

You have to hover over "Filter all members". Then click the triangular arrow that appears. Then you can make protected members visible.

It's kind of like a Scaladoc scavenger hunt. Or an escape room game. Except there is no escape.

@Jasper-M besides the eyes emoji, I have to say that is totally wild. TIL!

I didn't remember that one stupid trick for protected members when I lodged scala/bug#12670 which on second thought I won't close but leave as a follow-up: from the search bar, the page should automatically enable protected members if necessary.
