`run-kotlin` language name no longer works


#1

Hi,

some time ago @Roman_Belov demonstrated (see here) that runnable Kotlin code can be added to posts on this forum if you specify run-kotlin as a language name in ``` markdown syntax.

I noticed today that this functionality no longer works - is this a bug or was it disabled deliberately?


#2

Fixed now


#3
for(i in 0..5){
    println(i)
}

is it?
What am I doing wrong? I use
_```run-kotlin


#4
fun main(args: Array<String>) {
//sampleStart
    println("It needs a main!")
//sampleEnd
}

edit: oh, it works after i refresh the page
edit2: you can also put a //sampleStart and //sampleEnd to hide outside code :smiley:


#5

Mmmm. It’s still not 100% working. Every time I open up this topic it is displayed wrong and when I refresh it works again.


#6

The same behavior. Windows / Chrome latest


#7

I run Chrome as well, but on a mac and the link @forinil2 shared works for me. So something must be different about that old post


#8

No, the old post is also viewed as runnable only after refresh.

I was bored, so looking at the html of this site it seems like there is a div missing with class “executable-fragment-wrapper”, which only appears after reloading.

html

Before reloading:

<pre><code class="lang-run-kotlin">fun main(args: Array&lt;String&gt;) {
//sampleStart
    println("It needs a main!")
//sampleEnd
}
</code></pre>

After reload:

<pre><code class="lang-run-kotlin" data-kotlin-playground-initialized="true" style="display: none;">fun main(args: Array&lt;String&gt;) {
//sampleStart
    println("It needs a main!")
//sampleEnd
}
</code>

Nope, the executable-fragment-wrapper attribute appends only for the runnable code. Runnable examples always load after DOMContentLoaded event but some content on this page renders with JavaScript. Right now we are trying to fix this problem.

fun main(args: Array<String>) {
//sampleStart
println("Don't worry! Runnable examples just need a vacation!");
//sampleEnd
}
