Integrating Mull into a Bazel based project

[VinayDodamani]

Hello,

we are trying to include Mull into our project, which happens to be Bazel based. For doing that we need a BUILD.bazel file something similar to what googletest possesses, would be nice if there was some support for the same.

Hi @VinayDodamani, I somehow missed this issue, apologies for the delay 🙈
Do you have a good open source project in mind I can use as an example? I'd love to write a tutorial for this use case!

[VinayDodamani]

Hi @AlexDenisov thank you for your response, in my opinion the best project as an example would be the googletest https://github.com/google/googletest. Eagerly waiting for a bazel based Mull update. Thanks.

@AlexDenisov Do you had time to have a look into it? I think the first step would be to have a Bazel based build of mull, then it would be possible to build mull with the correct toolchain in a Bazel project.

Hi @PieterBunnenberg, I didn't have time to look into it yet.
Admittedly, I didn't think of Bazel based build of Mull, that's certainly an interesting perspective. Can you share some more thoughts of how a perfect integration would look like? That's would be highly appreciated!

Hi @AlexDenisov, I am sorry for my late response.
Sadly, I am not sure how a perfect integration would look like 😢. I will get in contact with my colleagues, I hope that I can come back with a solution. I still assume that we need a Bazel build of mull. This would allow us to build mull for our environment on the fly (LLVM 15 - Ubuntu 22.04).

Nether the less, I could try for now the prebuild mull package. Is it planned to provide that for Ubuntu 22.04 and LLVM15? I miss this in the latest release: https://github.com/mull-project/mull/releases/tag/0.21.0

@PieterBunnenberg I added Ubuntu 22.04 last night, the packages are now building, should be available in a couple of hours or so.

Hi @AlexDenisov, we figured out a way to use mull for bazel based projects after using the latest mull prebuild package, we would be more than happy to help documenting it, if it can help someone :)

[AlexDenisov]

That's a great news @VinayDodamani, congrats!
If you can add a little tutorial here, that would be appreciated!
Otherwise, you can share your learnings here and I'll convert them into a tutorial 🙌

Would love to hear about that!
