this one ^
that did the trick for me
also, try to set a breakpoint in the code somewhere, where it runs... that helps to bring up those debug windows
if the debugger is attached to the JVM process ( that should happen by pressing the green bug button )
Is there a way to run tests when exporting the project as ESModule? Im getting
Could not run test MainSpec: org.scalajs.testcommon.RPCCore$RPCException: scala.scalajs.js.JavaScriptException: TypeError: Cannot read property 'MainSpec' of undefined. I stumbled upon this thread: https://www.reddit.com/r/scala/comments/c84rae/unit_testing_in_scalajs/ but the solutions proposed there don't change anything for me
version is 0.6.28
The post at https://www.reddit.com/r/scala/comments/c84rae/unit_testing_in_scalajs/eskcrtc?utm_source=share&utm_medium=web2x should be enough to get things running.
The settings will have to be in the
.settings() (resp. .jsSettings()) of the relevant project (resp. crossProject)
Hi. I'm trying to set
global.process.exitcode to a non-zero value and then allow my program to exit gracefully. I am expecting to exit with a failure in that case but I am still exiting with a success. I have confirmed that I am using the node.js environment. Am I doing something wrong?
@JSExportAll
@JSExportTopLevel("Main")
object Main {
def main(args: Array[String]): Unit = {
println("abc")
args.foreach(println)
}
}node my-script-opt.js 3123 12312 12312312 3123123 12321312 1231231 12312312 123123
abc
Don't forget that node has the node bin and then the script name so
val args = process.argv.drop(2) to access the first arg. I typically have a separate project with 2-3 lines in it representing "main" and handling some major "context" instance specific to the environment. Same on the JVM side.
Well, I got something working here.
@JSExportAll
@JSExportTopLevel("Main")
object Main {
def test(s: Array[String]): Unit = {
println("ABC")
s.foreach(println)
}
}var main = require("./test.js");
main.Main.test(process.argv);It prints the ABC but on the foreach it's giving me a TypeError: Cannot read property 'length' of undefined. I'm using .jsSettings(scalaJSLinkerConfig ~= { _.withModuleKind(ModuleKind.CommonJSModule) }) and calling it using:
node myScript.js 123 123 123Any ideas?
outdated and unfinished minimal project notes: https://aappddeevv.gitbooks.io/scalajs-nodejs-cli-applications/content/cliscala.html
fullOpt is not suited for iterative development: it does not check undefined behavior, and takes way longer to compile.
I am trying to write something minimal, so I can generate a lot of test cases, call the jar file, call the JS file and compare both outputs

@oyvindberg and @jhegedus42 - Alright, I can test/debug shared files in IntelliJ by right-clicking the jvm package and choose Run or Debug. Thanks for your help and input. This is good enough for now. I'll probably file a bug report with IntelliJ that you can't do the same by right-clicking the individual shared files directly.

With tests, you can skip the "main" issue. An if you are new to scala/sbt, you could just write the JVM version, run it. Then copy the entire project to a new directory, add the scala-js plugin and %%% to the scalatest dependency. Then run the test in that new dir the same way.

When I do a publishLocal and try to run it I'm running into a ClassNotFoundException, so somehow it's not getting the scalalib and packaging together with my jar, any idea why?

^ specifically, here's the function I'd like to import: https://github.com/katzer/cordova-plugin-background-mode#override-defaults
@vivri you can define a
Then, when you write the facade for that function, you ask
trait NotificationOptions extends js.Object where you set the members that you can set being js.UndefOr[T] for T the type you need. For example val title: js.UndefOr[String] = js.undefined.Then, when you write the facade for that function, you ask
def setDefaults(options: NotificationOptions): Unit = js.native. And you can feed the argument by instantiated new instances of NotificationOptions (a method apply in the companion object is not a bad idea in general)
