# compose

[Timo Drick]

Is it possible to compile compose code as KotlinScript? Maybe someone can give me a hint. I think i have to enable the compiler plugin of compose. But i do not know how to do that.

[Mark Murphy]

My guess is that this devolves to: how to we get Kotlin compiler plugins and the IR backend to operate in a scripting environment?

[Timo Drick]

For me it would be enough when i can compile compose code during runtime inside of a kotlin program that itself is also compiled with the Compose plugin.

[Timo Drick]

Or more specific i want to compile it and execute it during runtime

[SrSouza]

I think you ask in #scripting

[Timo Drick]

Ok when i enable the compose plugin for the compiler i get now this error:
exception: java.lang.IllegalStateException: The provided plugin androidx.compose.compiler.plugins.kotlin.ComposeComponentRegistrar is not compatible with this version of compiler

[Timo Drick]

So it looks like compose still uses a modified kotlin compiler

[Adam Powell]

nah, no kotlinc modifications, compose has used standard kotlinc for some time now. it is tightly coupled with particular versions of kotlinc, however, as the plugin apis often change in incompatible ways. if you're using a newer kotlinc that compose hasn't been updated/tested against yet there's a flag to disable the version check and try anyway if you're feeling lucky. you should be able to find it searching this channel

[jw]

The flag also triggers with Kotlin/Native even if you're on the right version. So perhaps scripting behaves the same where you need to always disable the check.

[Timo Drick]

Do you mean this flag:Xskip-runtime-version-check unfortunatley i think i do something else wrong.

[Timo Drick]

So when i compile a very simple compose for desktop project with "./gradlew -d compileKotlin" i see the compiler arguments gradle uses in the line: contains :compileKotlin Kotlin compiler args:
When i use this arguments to run kontlinc i get this error. Also tried to add -Xskip-runtime-version-check.

the "caused by" looks like an incompatible change in the kotlinc <-> plugin interface layers between 1.4.31 and the kotlinc version you're using

[Timo Drick]

but i am using 1.4.31
Just downloaded this version

[Timo Drick]

kotlinc -version
OpenJDK 64-Bit Server VM warning: Options -Xverify:none and -noverify were deprecated in JDK 13 and will likely be removed in a future release.

[Timo Drick]

hmm ok maybe i could try to use openjdk 15

[Adam Powell]

I don't think that's going to change the underlying incompatibility between the versions of kotlinc and the compose plugin in play here

[Timo Drick]

I get the same error when i use K2JVMCompiler().exec(...) during runtime inside of a compose for desktop program and try to compile simple compose for desktop application.

[Colton Idle]

Maybe upload a sample project with this? I can try getting it to work on my local as well.

[Timo Drick]

Ok i created a project here: https://gitlab.com/compose1/runtime-compose-compiler
It would be really great if it is possible to get this running. Because than things like this:
https://kotlinlang.slack.com/archives/C01D6HTPATV/p1617387096360300
getting possible for Compose UI

[Timo Drick]

Hmm not sure why. But now it works for me 😄
Did not changed anything in the code.
Now i have to find out how to run it as script. Or maybe reload the class during runtime.

[Timo Drick]

It is very wired but it works. I can also executed the generated class file and see that Compose window is shown.

[Timo Drick]

Ok i think it was not working because i used

implementation(kotlin("compiler")) // instead of kotlin("compiler-embeddable")

And when i change this it takes only the other version when i reload all gradle projects not when i just compiled.

[Timo Drick]

But good news i was able to solve all my problems. And now it is working. So i can compile compose code inside of a compose application and can reload this code and execute it 😄

[Timo Drick]

Code is committed here: https://gitlab.com/compose1/runtime-compose-compiler
