Hi.
If you mean this then I will be a +1 instead.
Just, do not convert anything original java code to kotlin, and make sure
pure java user will not be affected.
And I don't really mind if you add some kotlin util class dealing with
kotlin things.

This sounds similar to our Log4j Kotlin API. It’s an adapter library to
integrate with Kotlin-specific features or APIs (they provide a mini
standard library on top of Java like how Groovy does).

Ah, right.
Yeah, the various Utils classes in other Commons libraries could be ported
as well.

Sorry for the late reply. I was asleep.
I was thinking of adding extension functions that map to the methods
provided in the Utils classes (however, some methods, such as StringUtils'
isNotEmpty(), do not need to be mapped as there are similar functions in
the Kotlin standard library).

Please explain, by example, how we would go in order to provide a Kotlin
release?
IIUC, your PR does not cover all of [Lang] (?).
Might be worth posting in a new thread (with the "[ALL]" prefix).

Of course.
Extension functions and properties are a language feature of Kotlin, which
allow a function/property to be called from a variable as if it was part of
the original class declaration:

Hi.
In what consists the "porting"? Could you give an example?
If it's straightforward and can be automated, it might be worth
creating the port for all the Commons components (as part of
the release) in a move that can potentially expand our team of
developers (if Kotlin programmers are willing to participate to
the "upstream" Java project, of course).

I've updated all the methods to call Apache Commons Lang methods.

Re: [LANG] Porting to Kotlin

There are a number of approaches you could take. Why not just a whole bunch
of methods that map directly to existing functionality, e.g.:
fun Boolean?.isNotTrue() = BooleanUtils.isNotTrue(this)
fun Boolean.toStringYesNo() = BooleanUtils.toStringYesNo(this)
It might be possible to automate and when making changes/fixing bugs, there
wouldn't be two places to change. Just a thought?
