reification raises some nasty questions of contravariance/covariance which I’m not sure I’ve ever seen anyone settle on “the correct way” of handling it.

can

Employer<YouTrackIssue>

be assigned to

Employer<Task>

or

Person<YouTrackIssue>

or….

or is the whole type the type. i.e.

Employer<T>

is generic, the reified one is concrete.

How do I parse a boolean from a string in Kotlin?

Boolean.valueOf() is shadowed by kotlin.Boolean, looks like.

Fully qualifying seems to work

java.lang.Boolean.valueOf("true”)

I’m sure there’s a… better way tho.

s.equalsIgnoreCase("true")

simple smile

I said a better way simple smile

There is no better way!

build a

Map<String, Boolean>

...

then you get O(1) conversions!

immutable map at least!

bools = hashSet(“true”)

Here is the JDK's version:

public static boolean parseBoolean(String s) {
        return ((s != null) && s.equalsIgnoreCase("true"));
    }

.contains

!

public static boolean String.isTruthyWuthy()

simple smile

Where is the best place to give language feedback?

youtrack probably

Thanks all, I ended up fully qualifying, although I like @cedric’s version simple smile

@cfleming: I congratulate you for your taste

Hi all. I have just created a new channel #C0CJB89LK for discussing all what is related to using kotlin in a startup environment, like for example advantages versus other popular choices today, like node.js or Go, best web-frameworks to use, integrate with and so on. If anyone interested please join the channel!

I have created #C0C7SMTU6 channel for Anko library which I think is essential for Android development with K

@damianpetla: isn’t the #C0B8M7BUY channel enough?

maybe simple smile, I can always remove that channel if there will be no activity

rule of thumb: if you already have an active discussion on a channel, and you find that the discussion is not interesting for some of the members on the channel, that’s when it makes sense to create a new one

(sorry, this should have been on #C0B8W32VA)

@cedric:

The C# guys didn't solve it that nicely, they are paying a heavy price for reification

what is that price?

Why is there no bitwise operator in kotlin?
