okay

we have a few devs at work who use eclipse, do you know anything about what kotlin development is like using it?

I've seen some complaints about the integration not being smooth - but TBH I didn't pay too much attention. The refactoring support in Idea is just much more powerful and for me that's a slam dunk. I think the Android Studio announcement was another massive win for JB.

I reckon very, very few developers use Eclipse for Kotlin. I don’t think the plug-in is being much worked on too

already asked in #general but looks like this is a more appropriate place

where can I find docs on kotlin html dsl? I am trying to create a web page with file upload and though I can find the relevant methods (I think so), I'm not sure how to use them properly and I can't find the docs anywhere but I believe they exist this page: https://github.com/Kotlin/kotlinx.html/wiki contains some minimal information, but it does not cover the DSL tags

@noncom what exact methods are you looking for?

@cy I am attempting to create a web form with the possibility to load a file

currently I am churning through the code on myself, figuring out things

I got some progress, like I can create a button to call up the file chooser

but am still in progress of finding out a way to actually implement what I need

it would be nice if there'd be docs...

though, I've found this example: https://github.com/ktorio/ktor/blob/master/ktor-samples/ktor-samples-post/src/io/ktor/samples/post/FormPostApplication.kt

but it is so ultimatly bare...

Can suspend functions not be called within a lambda?

private suspend fun scanProjects(
            projectMap: Map<String, String>,
            projectRepos: List<ProjectRepo>,
            runNumber: Long,
            projectsScanned: Set<String>) {
        launch {
            projectMap.forEach { key, projectName ->
                val allReposForProject = projectRepos.filter { it.projectKey.equals(key) }
                async {  processProject(key, projectName, allReposForProject, runNumber, projectsScanned) }.await()
            }
        }.join()
    }

Causes:

Kotlin: Suspension functions can be called only within coroutine body

#coroutines

@Ravi Hasija That is a

suspended

function, not a co-routine, suspended functions need to be called from within a co-routine. There are a few different ways to do that. Here is a simple example

val job = launch(CommonPool) { 
    val result = scanProjects(args....)
    println("$result")
}
println("The result: ")
job.join() // join is a blocking call...

That is if you are trying to get the entire

scanProjects

method to run in a co-routine

@Hawk I get the same error when I try to do below:

fun main() {

        if (!run) {
            logger.warn("Skipping AnalyzeDependencyRunner run...")
            return
        }
           try {
            val launch = launch(CommonPool) {
                scanProjects(projectMap, projectRepos, runNumber, projectsScanned)
            }
            launch.join()
        } catch (e: Exception) {
            log.error(e)
        }
    }

What am I missing? If I try with

runBlocking

above works

For example: below does not give me Compile error

fun main() {

        if (!run) {
            logger.warn("Skipping AnalyzeDependencyRunner run...")
            return
        }
           try {
            runBlocking {
                scanProjects(projectMap, projectRepos, runNumber, projectsScanned)
            }
        } catch (e: Exception) {
            log.error(e)
        }
    }

This too causes compile error:

fun foo() {
        async {
            val i =1
        }.await()
    }

Because

join

and

await

also need to be run in a coroutine.. they are also suspending functions. See kotlinx.coroutines docs, everything is explaned there with good examples 🙂

What does Devise do?

Authentication

#coroutines Any way to specify number of threads for coroutine context? I couldn’t find the information. Please let me know if you know/have a good resource.

@ravi.hasija

val heavyWorkerPool = newFixedThreadPoolContext(numberOfThreads, "heavy-worker")

Boom @dave08 Thank you!

anyone in here using dropwizard with liquibase? I’ve some questions about using a sql file for migrations

Some exciting news. As of v3.2.x, http4k now supports (typesafe and testable) Websockets. https://www.http4k.org/blog/typesafe_websockets/ It's on reddit kotlin if anyone feels like upvoting it 🙂 https://www.reddit.com/r/Kotlin/

kotlin conf app?
