How use bazel-gazelle in cpp project? #910

There's no native support for C++, but you could write an extension (see https://github.com/bazelbuild/bazel-gazelle/blob/master/extend.rst). |
|
@roderick-liu I may be working on a C++ Gazelle extension soon, if you are interested in collaborating. |
|
Is it possible to get some info about any c/c++ build file generation that Google already has? I’ve seen references to an unsupported “googlify” script that you can run on code checked into third_party. I suspect a c++ extension won’t be remotely as straightforward as Go’s build system was heavily influenced by Blaze 😰 |

Some members of the Bazel team have been working on AOSP support for some time: See https://android-review.googlesource.com/q/owner:jingwen%2540google.com, https://blog.bazel.build/2020/11/12/aosp_migrating_to_bazel.html, and Bazel's undocumented native ninja rules: https://github.com/bazelbuild/bazel/tree/master/src/main/java/com/google/devtools/build/lib/bazel/rules/ninja |

Hello, I came here after seeing a recent BazelCon video, https://www.youtube.com/watch?v=ol5hwjr48Q4 where the presenters share that they added gazelle rules for c++ and hence facilitated developers' overheads in their project, which is great. I searched online but couldn't proceed further. Are there any updates on this thread, i.e. have you managed to proceed? Thanks |
|
Any update on C++ Support? |
|
@disdi @HALtheWise @roderick-liu My team is interested in the c++ extension as well. Would anyone be interested in a collaboration? If so I'll submit a new issue saying we'll (attempt to) add it |
|
Is there any place where I can find more about ongoing efforts on this? Gazelle for C++ would be great. If anyone already started working on it I'd love to take look. |
|
hey alberto our team actually went ahead and created a decent mvp for c++, Going to start working with my company to OSS the solution - we've gotten pretty efficient so it shouldn't take long |
|
Hey @pieknik can you publish your MVP somewhere ? I would be curious to see if/how it works. |
|
I found that video too, @nnWhisperer, and I had the same question. @pieknik have you had any luck getting the MVP open-sourced? |
Changes: - Establish a mechanism for defining external python requirements via a `requirements.in`, generating updates to a lock file with `bazel run //:requirements.update` - Configure gazelle python and protobufs - Configures via gazelle directives to use a file based approach, stick with the BUILD configuration, disable go, default visibility to private and resolve py imports - Update dev_setup to install openjdk (java), tree, ranger, ag New Commands: ``` bazel run //:requirements.update bazel run //:gazelle_python_manifest.update bazel run //:gazelle ``` New Tests: ``` //:requirements_test //::gazelle_python_manifest.test ``` Notes: - One of the recurring issues I have every time I deal with updating WORKSPACE is slight incompatibilities with various repos that result in incomprehensible output errors. - stackb/rules_proto is one of the only things that seems to support what I'm looking for, and while it is getting steady contributions hasn't pubilshed a release in about a year. https://github.com/rules-proto-grpc/rules_proto_grpc. Additionally, it could be handy to look into what it would take to make my own "shitty" version of these rules to learn more about what's going on in gazelle's / bazel's internals - bzlmod migration didn't go well for me, most tutorials out there still use WORKSPACE, might be good to look into in the future / figure out how to migrate piecemeal, but bypassed this and 7.0.1 bazel upgrade for now Related Issues: - Noting the issue with requiring a gazelle directive for proto libraries: bazelbuild/rules_python#1703 - bazelbuild/rules_python#1664 fixes the reason I had to "disable" my py_binary, wait for that to release and then update. I could probably patch this in, but don't quite know how 🤷 - Sounds like there's some talk around gazelle c++ bazelbuild/bazel-gazelle#910 - I'm helping ;) bazelbuild/rules_python#1712 (doc update) References: - https://github.com/bazelbuild/bazel-gazelle - https://github.com/stackb/rules_proto - https://github.com/bazelbuild/rules_python/tree/main/gazelle Future Things to Look Into: - Setup a gazelle test that checks output of `//:gazelle -- -mode diff` is zero - Configure rust with gazelle: https://github.com/Calsign/gazelle_rust - A really cool / general parser / generator (what github uses for "semantic" tool): https://tree-sitter.github.io/tree-sitter/ Could use to make small code generator / modification? Or maybe more general utilities? - General compile command completion: https://github.com/hedronvision/bazel-compile-commands-extractor - Maybe play with https://github.com/rules-proto-grpc/rules_proto_grpc as an alternative to stackb - If I can't use gazelle for some things, mess around with https://github.com/bazelbuild/buildtools/tree/master/buildozer
hi
It is a very useful tool in golang project. Does it been used in cpp project?
