Support Hover on declarations

[fwcd]

Show type information upon hover on a declaration.

This doesnt seem to be working for me on latest commit.

@Strum355 Could you please paste the output log?

[Strum355]

[INFO]      async0      main    Hovering at file:///home/noah/Kotlin/main.kt 5:8
[INFO]      async0      main    Re-parsing main.kt 5:5-6:26
[INFO]      async0      main    Compiling var x = something(10)
[INFO]      async0      main    Finished in 27 ms

fun something(x: Int): String {
    return "test ${x}"
}

fun main(args: Array<String>) {
    var x = something(10)
    println(x)
}

Hovering over x in the println call gives the correct hover, however hovering over x in the previous line gives nothing. Unfortunately this is all the log says. Is there a more verbose log i should enable?

[fwcd]

@Strum355 Ok, I will look into this soon. Sometimes the LS fails to infer a type, but should show an [ERROR] type upon hover nevertheless.

@Strum355 I can't reproduce the issue.

The language server does not throw a stack trace either according to your log, so I suppose you are still somehow running an older version. Did you try building the the repo yourself or are you using the version on the VSCode marketplace?

Ah yea it works from master, marketplace one must be an older one then. I dont remember if i was running from master in Extension Development mode or not at the time that I noticed it wasnt working. My bad ^^
