I guess a solution would be to compile it to WASM ourselves |
I think in the short term it's fine since we use a fixed version of the npm package and we don't update the clang-format rules often. In the long term, compiling it to WASM or deferring to system-wide installation to a fixed version can be considered. Not sure when/how it was added to the CI but I think it would be fine removing it from the CI if using an old version ends up being problematic & we can't come up with a better solution - then we just go back to suggesting whitespace changes manually in the code reviews and hinting that clang-format vx.y can be used for those who don't know. |
I'm not too big into wasm, but I'm very curious why people keep mentioning it here. Clang, and all of its tools, rely quite a bit on parallel execution and the file system. Have things changed in wasm so far that either of those are possible? I'm also not too into the workings and preferences of node, but I'm confused about why an npm package -- which appears to just build clang-format from source and layer on a cli-to-the-cli -- was used. What am I missing? Why can't the actual clang-format package be used? Edit: To be clear, I'm just curious. I don't mean to sound snarky. |
I have not looked into clang-format so I don’t know if it needs any parallel file execution, but I doubt it needs anything very sophisticated as it’s just a formatting tool. Technically it just works on one file at a time and can also just read from stdin. We only use clang-format to format C++ code. We use the npm package because alas the llvm project does not distribute prebuilt clang-format binaries for multiple platforms (which is actually tiny) and the package does what we need - prebuild and distribute the binary for different platforms and download it during installation. |
The title here is a bit misleading. I checked the Internet a bit and can't seem to find any other credible & versioned pre-built binaries. VScode's C++ plugin has one that's maintained by Microsoft but the download links aren't versioned. Chromium/V8 uses another one (documentation) maintained by Google and also the download links aren't very well versioned (although, theoretically we can still use the links in certain version of depot_tools's DEPS file, but it doesn't feel quite right to piggyback like this :)). llvm has prebuilt binaries but I am not sure which one of these archives contain clang-format and even if they do, they are too big - clang-format itself is tiny. It can be easily built from source https://github.com/llvm/llvm-project/tree/main/clang/tools/clang-format Maybe something we can look into is setting up a GitHub repo with a workflow that just builds https://github.com/llvm/llvm-project/tree/main/clang/tools/clang-format and uploads the binary as releases that |

Another possible solution is to use some script that install a certain version of clang-format for different platforms. Most Linux distros provide some package that contains clang-format and on macOS there are e.g. homebrew formulas. Question is how do we ensure that the exact same version is installed for different platforms because different versions of clang-format can produce different results. |
I also found this https://github.com/muttleyxd/clang-tools-static-binaries which contains a workflow to build and release the binaries for Linux, macOS and Windows (it even builds all the versions from clang 3.9 to 17, and contains other clang tools). Maybe we can use the releases there or, if we are not too comfortable with using a third-party one, we can just fork it and build our own. I think for us, the latest stable release of clang-format is enough. Though it would also be interesting to include the other tools and e.g. replace cpplint with clang-tidy (which can do a lot more in-depth linting and has a handy |
If you're looking for a single package with a known, immutable version that works just about anywhere, then Nix is the droid you are looking for. |
FWIW I just forked the clang-format repo and I'm looking into creating builds using GH actions: https://github.com/targos/clang-format/tree/test-build |
