Question

Hello Me and my team are trying to contribute to Pulumi by adding JVM support I have question how the language specific classes are being generated in `sdk ` folder I wrote minimal Java code generator `gen go` which generates `Config java` file Also I discovered that `GeneratePackage ` function is executed only in tests and I guess this is main entrypoint for generating files right But I found out that code is being generated inside the internal testdata folder Could you give us some information how Pulumi team generates language files in `sdk ` folder

Awesome As I m sure you are already aware JVM support for Pulumi is a highly upvoted request from many members of the broader Pulumi community The steps required to bring up support for a new language in Pulumi are outlined at The core Pulumi SDK bullet 2 in the list above is hand written for each language All other SDKs for packages are auto generated using the generators in The `GeneratePackage` functions for each language are called from the various package generators including for all Terraform Bridged providers for the Azure Native Provider Etc

thank you < white balloon 205> just to clarify content of this directory was hand written or auto generated if not generated then what config is generated here if note the one in core wouldn t want to write a ton of Java by hand just to realize it should be generated also we ve started some basic scaffolding and gRPC generator here please advice when is a good time to do a WIP PR

bored-oyster-3147 · Answer

< brave dawn 64711> the Core SDKs that are in the first repo you linked are hand written I believe the SDKs that are auto generated are the ones for the providers Such as

bored-oyster-3147 · Answer

Note the Config generation you linked is defining a static Config class in the new namespace but is then defining a static readonly Pulumi Config property thus assuming that Pulumi Config is already defined elsewhere

thanks all clear slightly smiling face

brave-dawn-64711 · Answer

when should we start thinking about a PR what kind of maturity metric lvl

billowy-army-68599 · Answer

< brave dawn 64711> i think the best time for a PR is when there s a working prototype with some tests < bored oyster 3147> did a great job with the C Automation API implementation

It would be good to capture this discussion in <https github com pulumi pulumi discussions>

white-balloon-205 · Answer

Related to < worried city 86458> s suggestion < numerous piano 36614> < brave dawn 64711> definitely interested to hear if you ve made any more progress here If you d like to find time for a quick call to discuss plans here happy to find some time

brave-dawn-64711 · Answer

sorry for late response I was on a small vacation

brave-dawn-64711 · Answer

there is a slow but steady progress to figure out what the c implementation is doing and how to express it in Java

brave-dawn-64711 · Answer

with an occasional look at other implemeentations

brave-dawn-64711 · Answer

not sure if this is too early for a call since the implementation does not even compile since it is very incomplete right now

brave-dawn-64711 · Answer

btw a Slack Connect channel for jvm related discussions could be an idea wdyt

brave-dawn-64711 · Answer

< white balloon 205> progress report ``` 1 to 1 ish port of C SDK implementation to Java mostly complete implementation Automation API is missing it compiles unit tests run Current Limitations changes in usage and implementation due to lack of generic types reification in Java lack of AsyncLocal lack of AsyncIterator``` There are a lot of TODOs also needs rebasing but there is already a lot of code written and it took a lot longer than I anticipated so just to be sure no one is duplicating this effort slightly smiling face Next we ll finish an initial implementation for the code generation and try to generate some providers

broad-dog-22463 · Answer

This is fantastic < brave dawn 64711> thank you for this Can we get you set up for a call with the team to discuss this

bored-oyster-3147 · Answer

Hey You guys might want to include < limited rainbow 51650> I know he was working on or planning on working on a barebones Automation API implementation in Java So that might be your missing piece

bored-oyster-3147 · Answer

To be clear he was going to do Automation API without inline program support without the core SDK so he would have minimal to no overlap with your work but might be worth seeing if there are touchpoints

brave-dawn-64711 · Answer

< broad dog 22463> that would be great we just need to figure out a date I m guessing your morning and my evening should work I m in UTC +2

< white balloon 205> Hand written Kubernetes provider API for Java prototype as requested

brave-dawn-64711 · Answer

lack of reified types required some kind of solution and those annotations are the cleanest thing I came up with without implementing my own reification

brave-dawn-64711 · Answer

it works with an actual kubernetes slightly smiling face
