Release 0.11.0

Darwin can build cargo2nix on nixpkgs-unstable. Examples build on most nixpkgs branches on Darwin.

Added

• re-added flake-compat (and this time it doesn't complain when using nix flake show)
• Support for passing in a rustToolchain from any way you want to provide Rust
• Development workspaceShell customization pass-throughs to Nix's standard mkShell function
• wasi cross compiling example (runs on Linux only)
• combined overlays for easier consumption when writing your flake.nix

Changed

• removed localPatterns completely
• git sources no longer do IFD from readFile use
• CI uses rev from the PR
• local registry support removed (unused)
• overhauled rustChannel argument
• Rust support to 1.60
• Nixpkgs to 21.11
• The -f flag was changed to default when calling cargo2nix

Lots of code cleanups**

• makePackageSet' -> makePackageSet

• utils.sh -> mkcrate-utils.sh

• simplified.nix & full.nix -> user-facing.nix & internal.nix

• Docs updated

Fixed

• defaultApp updated to nix 2.8 style
• direnv uses newer nix style
• rustTriple
• eliminated non-determinism in Cargo.nix output to help reduce line noise
• openssh cross compile correct build & host offsets / platforms
• Darwin can build cargo2nix (with nixpkgs-unstable) as of this writing
• JSON messages rendered to output for easy reading nix build logs

Release 0.10.0

This release contains many changes that will require updating Cargo.nix and nix expressions for existing projects. See the updates to examples for more information on how to make the change. It's relatively easy since nix flakes have a better defined structure.

Nix Flakes

With this release, cargo2nix will no longer be attempting to support legacy nix commands or legacy nix build expressions. Many may still work, but there will be no further attempt to fix issues or remain compatible with flakes. The benefits of flakes, even to beginners because of the additional structure, is too valuable to be able to justify the maintenance overhead for a usage pattern that likely is barely working even where it is.

The flake commands are really great for rapidly getting started. nix develop and nix shell github:/cargo2nix/cargo2nix are just two awesome examples. Of leveraging flakes to make dependencies easier than ever.

CI With Actions & Mac Support

Cargo2nix and some examples now build on mac for CI. This will allow our (more common) Linux users to make PR's without accidentally breaking the bootstrap workflows for Mac users. (you need a working Cargo2nix to conveniently develop Cargo2nix).

Rust 2021 Edition and Cargo 0.57 (Rust 1.57) Support

All of the latest toml and Rust language features are supported

Other Changes

• fixed hostPlatformFeatures
• support for profile-opts and codegen-opts (this likely needs a second pass for architecture. Note as experimental)

• git branches in Cargo.toml sources #174
• fix for localPaths when using workspacePath 180
• several jq and remarshal issues were worked around 171
• switched Rust overlay to Oxalica 178
