conan-flake

The conan-flake module bridges the gap between Nix and the Conan C/C++ Package Manager, supporting a declarative configuration style and common development workflows.

For a user profile configuration like the following:

[settings]
build_type=Debug
compiler.cppstd=14

[platform_tool_requires]
cmake/X.Y.Z

There correspond the following options:

{
  profiles.default = {
    settings.build_type = "Debug";
    settings."compiler.cppstd" = "14";

    platformToolRequires = {
      cmake = pkgs.cmake.version;
    };
  };

  devShell = {
    # Programs you want to make available in the shell:
    tools = { inherit (pkgs) cmake; };
  };
}

The conan-flake module works with plain Nix (no flakes), Nix flakes, flake-parts, or as a devenv module.

Where to go next

• Getting started takes an empty directory to a working Conan configuration, using one of the templates.
• flake-parts covers the flake-parts integration.
• devenv covers the devenv integration, both through devenv’s own languages.cplusplus.conan option and with conan-flake used directly as a devenv module.
• Standalone covers plain Nix usage, with and without flakes.
• Toolchains covers the LLVM/libc++ and CUDA scenarios.
• The option reference lists every option of the module, generated from the module itself, along with initial setup instructions for flake-parts scenarios.
