an idea to the horrible replacement suggested for capitalize() : Gradle is using capitalized()

[Joffrey]

It still doesn't solve the actual initial problem with capitalize. The point is that it's unclear what this does, and many devs have different expectations depending on their background. Does it capitalize every word? Just the first character? With which locale? Does it lowercase other letters of keep them uppercase if they are uppercase to start with?

just the first, default locale

That's your opinion of what should go behind the name capitalize(d) . The reason the Kotlin team deprecated this function is that there was no consensus on this, and therefore it was better to keep more specific helper functions, like replaceFirstChar and see how users combined them. Once this data is clearer, maybe a new helper will be provided in the stdlib, with a name adapted to the most common usages/use cases.

@elect Note that the suggested replacement is wordy only because it tries to preserve the behavior of the replaced function as accurately as possible. But in most cases something more compact as replaceFirstChar { it.uppercase() } may be sufficient.

If uppercase() is unambiguous than so should uppercaseFirstChar()?

This and pascal/camel/snake case conversions come up quite often.

Actually replaceFirstChar { it.uppercase() } is probably also not what people should be using. Most probably people are looking for replaceFirstChar { it.titlecase() } instead (see the stackoverflow answer linked above), and thus introducing uppercaseFirstChar would probably be a bad idea, but I see your point (we could make the same point with titlecaseFirstChar).

The thing is, replaceFirstChar is a general function which can be combined in a more flexible way. It makes sense to understand actual needs before releasing functions in the stdlib.

That said, I agree that pascal/camel/snake case conversions would be useful to many people, as well as capitalization of single-word strings
