Current rust not usable with IDE plugins - missing stuff

[mouse07410 (Mouse)]

The current port (1.32.0) does not include rust std library, nor the mechanisms to automatically download it. This makes it impossible to use rustc and other rust-related ports with an IDE plugin, such as IntelliJ-rust for IntelliJ IDEA (or CLion).

It would be nice if this port would be self-contained.

Also, it seems to depend on llvm-6.0. It would be nice if it could at least depend on llvm-7.0 (how many llvm's do I need to keep installed on my machine?).

Thanks!

I'm assuming you mean the rust std library source code, (the binary version is included in the compiler). You can install that using port install rust-src, and that should work. I'll make some tests with llvm 7 and see how it goes, if it works correctly we can use that.

In the future, I could add some notes explaining what is needed to use rust in an IDE.

Unfortunately, I'm a beginner in rust - so cannot validate your assumption. Probably you are right.

Yes please. Also, as I'm a beginner with Macports too, I don't know if the following is possible:

• set the lowest acceptable version of LLVM
• configure the rust port to use whatever LLVM is installed as long as it's not older than the lowest allowed
• if no LLVM is installed - install the latest available (IMHO, the likelihood that it would break rust is low, but if it does and users report that - you can always place high-version restriction; I just don't want that restriction in place until and unless it's proven necessary)

YES PLEASE! Also, IntelliJ IDEA ​https://www.jetbrains.com/idea/download/?utm_source=product&utm_medium=link&utm_campaign=IU&utm_content=2018.2#section=mac has a free Community Edition. You can try downloading it, installing Rust plugin, and see for yourself what works and what doesn't - and then document how to go about using it with the Rust ports.

Thanks again!

We usually strive to have reproducible builds, and that also means that dependencies should be fixed and not generated based on what's available. I can say that the rust build with LLVM 7 compiled correctly :) if that works well, I'll switch the port over to LLVM7

Yep, that's what I also use (with rust-src installed)

Could you describe how you configured the IDEA plugin? I.e., what directories/files did you point Toolchain Location and Standard Library?

Sure! Toolchain location is /opt/local/bin, standard library is /opt/local/share/rust/src.

Thank you! Perfect.

We are currently building with LLVM 9, so I'm closing this as fixed.
