quickjs-kt's Issues

Undefined Symbol for arm64 on linking

Hi,

I have a Kotlin Multiplatform project that fails at the linking step when building for iOS (device or simulator).

Here is the stack in XCode when trying to build :

ld: symbol(s) not found for architecture arm64

Steps to reproduce :

  • Create a new kotlin multiplatform project from their wizard here
  • Add implementation of quickjs in the sourceSets in build.gradle.kts of the shared module
  • Call a quickJs method in Greeting.kt in commonMain in shared module
  • Open the XCode project in iosApp folder
  • Try to build

Any idea of where it comes from ?

Thanks for your help !

Exception handling

Can you add a section to the README on how to properly handle js exceptions?

This does not work if an exception occurs in the js code. An error is thrown but this does not catch it:

                val result = try {
                    wrapper.evaluateJs(jscode)
                }
                catch (e: Exception) {
                    Logger.e { "Javascript error: $e" }
                    null
                }

throws this error:

...

This js code works as expected when I define my own host.log function, but it would be nicer if I could catch the error in kotlin:

                    try {
                      doStuff();
                    }
                    catch (err) {
                      host.log("caught js error: ", err);
                    }

thanks for all your quick updates!

suspend functions

Have you tried to use a suspend function via reflection, as shown below? I'm getting an error "parameter count mismatched"

class Http {
    suspend fun fetch(url: String) = "..."
}

quickJs {
    define<Http>("http", Http())

    evaluate<Any?>(
        """
        await http.fetch("https://www.example.com")
        """.trimIndent()
    )
}

Fix leaks

There are some leaks in the JS runtime after evaluation. They won't crash JS_FreeRuntime but need to be fixed.

Correct error handling for async functions

Currently, all jobs will get canceled if one throws an error, regardless of whether they have been caught in JavaScript.

The behavior needs to be implemented correctly.

Proper way to detect circular references

Currently, the detection of circular references not working on deep-level circular references:

// Not able to detect in this case
val set = mutableSetOf<Any?>()
val array = arrayOf(set)
set.add(array)

Need to re-implement the detection code.
