is there anywhere a development or testing guide for the ide plugin? just

./gradlew publishAndRunIde

? or

./gradlew clean gradle-plugin:publishArrowPluginMarkerMavenPublicationToMavenLocal gradle-plugin:publishPluginMavenPublicationToMavenLocal idea-plugin:runIde -Dorg.gradle.debug=true -Dkotlin.compiler.execution.strategy="in-process"

Should we close open PRs for arrow-meta in the old project then and open up the PRs in this new repo?

Hi, so I see that Lenses for now are CompanionObject.iso. Do you know how we can generate and make available for autocomplete intermediate methods like extension vals for Lenses

inline val <A> Lens<A, MyObject>.myObject2(): Lens<A, MyObject2> = {}

Hi! I migrated my work-in-progress PR over to

arrow-meta

, made sure that the gradle was synced to itself, set the JDK to 1.8, ran the

./gradlew

tasks in the CLI, and tried to run the tests from the IDE. Unfortunately, I'm getting this:

We’re defining the TestEnvironment for HeavyTests. Does anyone know how we can run code strings through our compiler plugin and pass the generated meta data (e.g.:

.class

) to a directory, which is within the Idea Instance we create during each test. Similar what we do know with the existing compiler plugin test’s. We’re blocked on that.

Now, I did remember to include the imports for the test, and I included the annotations and core data dependencies within the configs!

The issue is that @extension in current arrow can only target classes and interfaces but in meta we redeclared it to target much more

raulraja

10/30/2019, 7:50 PM

@Rachel that also needs to change in Arrow so val fun, object and class can use

@extension

Since we want to release SNAPSHOTs, we must find a way to connect release gradle plugin to snapshot Kotlin plugin. Or can we release gradle plugin snapshots without verification?

Which version of IntelliJ are you targetting with the

idea-plugin

module? I'm asking because the upcoming 2019.3 cleans up many deprecated methods and parts of the test framework will change, too

building

master

arrow-meta

takes about 6 minutes here. I've found that it only takes about a minute when using gradle's offline mode (flag

--offline

in a terminal and https://www.jetbrains.com/help/idea/jetgradle-tool-window.html#offline for the setting in IntelliJ)

gradle --info build

is showing lots of (failing) HTTP requests, I'm not sure why. @Imran/Malic

I'm trying to use "testing-plugin" in module "idea-plugin". The build is failing because it can't locate

com.github.arrow-kt:kotlin-compile-testing:1.2.3-SNAPSHOT

. I've tried

1.3.0

and also

com.github.tschuchortdev:kotlin-compile-testing:1.2.3-SNAPSHOT

, but this also failed. I've seen the thread above, but

1.3.0

doesn't seem to work here. Is there a way to make this work? @Imran/Malic

Btw why did you wrap my compile-testing library? Is the API not good enough?

raulraja

The API is great but we want meta users to use the same style they use in quotes, codegen, ide and tests

additionally we need to add to the DSL the quote system which is a compiler phase

basically inline plugins that are written in the tests

and we are trying to figure that out

you are welcome to suggest improvements, the only issues we had with your lib so far is that we had no version to rely on so we had to use a jitpack fork

tschuchort

11/02/2019, 12:04 PM

What do you mean with same style? If any improvements can be upstreamed I definitely want to do so, so that everyone can benefit from them.

For inline plugins you need the PR for better compiler plugin support, which is practically finished except for finding out the kapt-initialization order. We need to know if third-party compiler plugins are run before or after kapt stubs generation (or maybe not at all in the kapt-step). If you could find that out it would be a big help and I could merge&release it immediately. Should be enough to add some dummy method to classes in a compiler plugin and then observe in an annotation processor if it appears or not.

Hi @tschuchort, thanks for your help! I made a drawing to tell what we did:

In this way, tests can be written like this one: https://github.com/arrow-kt/arrow-meta/blob/master/compiler-plugin/src/test/kotlin/arrow/meta/plugins/lens/LensTest.kt
