Has any1 had success compiling it on mac? I get a link error involving libclang.

      thread 'main' panicked at 'Unable to find libclang: "the `libclang` shared library at /usr/local/opt/llvm/lib/libclang.dylib could not be opened: dlopen(/usr/local/opt/llvm/lib/libclang.dylib, 2): Symbol not found: __ZN4llvm11raw_ostream10resetColorEv\n  Referenced from: /usr/local/opt/llvm/lib/libclang.dylib\n  Expected in: /Users/erin/.rustup/toolchains/nightly-x86_64-apple-darwin/lib/libLLVM.dylib\n in /usr/local/opt/llvm/lib/libclang.dylib"', /Users/erin/.cargo/registry/src/github.com-1ecc6299db9ec823/bindgen-0.55.1/src/lib.rs:1896:31

That's from doing "cargo install pijul --version 1.0.0-alpha".

Bonus question: I'v never seen the notation "[0,n[" to represent a half-open internval before (I've seen "[0,n)"), but it does have a certain logic to it! Is it novel or standard in some places?

It looks like you don't have libclang. The required libraries are openssl libsodium llvm(which contains libclang) xxHash zlib zstd libgit2 pkgconfig

edit: with nix on macos, this 'should' be enough

   $ nix-shell -p openssl libsodium llvmPackages.libclang xxHash zlib zstd libgit2 pkgconfig rustc rustfmt cargo darwin.apple_sdk.frameworks.CoreServices darwin.apple_sdk.frameworks.Security darwin.apple_sdk.frameworks.SystemConfiguration
   [nix-shell] $ cargo install pijul --version 1.0.0-alpha --features git

Well, I think I have it installed (via brew), and the .dylib exists, it's just that doesn't have the spcific mangled symbol Rust is looking for inside the library. Feels like a version mismatch or something.

Edit: The nix tip worked; thanks!

I've been meaning to try out nix for a while anyway, so this was a nice nudge. :-)

Yes, it's standard in France at least.

Actually, both notations are described by an international standard, according to Wikipedia [1]

Very interesting! I'm surprised I've never encountered it before.

Thanks for Pijul; I'm super-excited about the possibilities. (Unlike many HN commentators, who are too trapped inside the git way of thinking to realize its limitations ;-)

I think your biggest challenge now is going to be everything besides the software itself that makes a project successful: Is the website fast and inviting? Is the software easy to install? Etc.

Thanks again & wishing the best for Pijul.

> Is the website fast and inviting? Is the software easy to install? Etc.

A very gentle way of phrasing this ;-) Thank you.

The Nest used to be really fast with the previous Pijul, but I remember the first iteration took a few days of debugging under full load before being stable. I'm not expecting it to be fast until a week or two.

The notation [0, n[ is standard in Germany.
