Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog and this project adheres to Semantic Versioning.

Unreleased

Changed

• Breaking: dropped compatibility for Nix versions below 2.24.10
• Breaking: dropped compatibility for nixpkgs-23.11
• mkDummySrc has been reworked to match cargo's autobin detection logic, meaning that only real binary targets defined by the project will be dummified if they exist (no more injecting src/bin/crane-dummy-*). This does mean that adding a new bin target definition will invalidate caches and require rebuilding all dependencies once more. (If this is a frequent enough occurrence for your project to cause headaches, please open an issue!)

Fixed

• mkDummySrc will deduplicate discovered and declared binary targets when dummifying sources
• crateNameFromCargoToml will ignore store contexts when parsing a Cargo.toml file (avoiding errors like the string ... is not allowed to refer to a store path).
• vendorGitDeps will perform a basic URL-decoding of git dependency entries in the Cargo.lock file since lockfiles now encode special characters starting at version 4

Meta

• Dropped support for publishing releases to https://flakestry.dev/

0.19.4 - 2024-11-30

Fixed

• removeReferencesToVendoredSources now deduplicates any found references to avoid pathological memory usage before removing them.
• buildDepsOnly will calculate fallback pname/version/cargoVendorDir attributes using dummySrc if it was specified (rather than attempting to use src)

0.19.3 - 2024-11-18

A republish of 0.19.2 which was incorrectly tagged.

0.19.2 - 2024-11-18

Added

• Added a number of fileset helpers to more easily compose source filtering:
  • fileset.cargoTomlAndLock: for Cargo.toml and Cargo.lock files
  • fileset.commonCargoSources: for files commonly used by cargo projects
  • fileset.configToml: for config.toml files
  • fileset.rust: for *.rs files
  • fileset.toml: for *.toml files

Fixed

• buildTrunkPackage will pass in --release=true (instead of just --release) for trunk versions 0.21 or higher to avoid argument ambiguities
• buildTrunkPackage will now correctly honor buildPhaseCargoCommand if specified (previously the value of buildPhaseCommand was incorrectly being used)
• removeReferencesToVendoredSourcesHook avoids referencing /dev/fd directly since it may not be present on certain platforms

0.19.1 - 2024-10-12

Added

• cargoDocTest is now available as an alternative to cargoTest which runs only doc tests.

Changed

• buildDepsOnly now sets CRANE_BUILD_DEPS_ONLY as an environment variable when it runs. Build hooks can use this as a shortcut to determine whether running inside of a buildDepsOnly derivation in case they need to tailor their behavior accordingly.

Fixed

• Vendoring dependencies avoids creating malformed TOML configurations in situations where registry name/url definitions cannot be found. When this happens a warning will be printed out during evaluation to highlight the issue.

0.19.0 - 2024-09-25

Added

• taploFmt is now available for checking TOML formatting

Changed

• Breaking (technically): buildPackage no longer adds jq to nativeBuildInputs as doing so can result in rebuilding any *-sys crates which rely on PKG_CONFIG_PATH remaining stable
• Breaking: downloadCargoPackageFromGit now takes hash instead of sha256 when specifying an output hash for the download
• installFromCargoBuildLogHook no longer assumes or requires that jq is available on $PATH and will instead directly reference pkgs.jq
• downloadCargoPackageFromGit will now set fetchLFS = true when fetching git repos with defined output hashes

Fixed

• cargoDoc correctly honors docInstallRoot when specified
• cargoDoc falls back to installing from ./target/doc even if $CARGO_BUILD_TARGET is set but ./target/$CARGO_BUILD_TARGET/doc does not exist

Removed

• The deprecated top-level (flake) attribute lib no longer exists. Please use mkLib with an instance of pkgs instead.

0.18.1 - 2024-08-22

Fixed

• Fixed vendoring dependencies from an alternative registry which they themselves have dependencies on crates from other registries.
• Fixed cargoNextest's positioning of cargoExtraArgs to form a valid command invocation when specified.

0.18.0 - 2024-07-05

Changed

• Breaking: dropped compatibility for Nix versions below 2.18.2
• Breaking: dropped compatibility for nixpkgs-23.11.
• The guidance around using (both) cleanCargoSource and path has been updated. Namely, it is no longer necessary to call both (e.g. craneLib.cleanCargoSource (craneLib.path ./.)): it is recommended to either use craneLib.cleanCargoSource ./. directly (if the default source cleaning is desired) or craneLib.path ./. (if not).
• overrideToolchain has been updated to better handle cross-compilation splicing for a customized toolchain. This means that overrideToolchain should now be called with a function which constructs said toolchain for any given pkgs instantiation. For example: craneLib.overrideToolchain (p: p.rust-bin.stable.latest.default)

Fixed

• The cross compilation example also hows how to set the TARGET_CC environment variable which may be required by some build scripts to function properly
• vendorCargoDeps and crateNameFromCargoToml do their best to avoid IFD when src is the result of lib.cleanSourceWith (and by extension cleanCargoSource)
• removeReferencesToVendoredSources handles the edge case where cargoVendorDir does not point to a path within the Nix store
• It is now possible to use .overrideScope to change what instance of craneUtils will be used during vendoring.

0.17.3 - 2024-06-02

Fixed

• removeReferencesToVendoredSources correctly signs aarch64-darwin builds (which was accidentally broken in 0.17.2)

0.17.2 - 2024-05-26

Fixed

• removeReferencesToVendoredSources has been optimized to search for source references only once. For derivations which install many files, this phase can run up to 99% faster than before.
• cleanCargoToml now cleans underscored versions of the same attributes (e.g. lib.proc-macro and lib.proc_macro)

0.17.1 - 2024-05-19

Fixed

• downloadCargoPackage and downloadCargoPackageFromGit no longer run the fixup phase by default, avoiding issues with source directories and files being moved to different locations
• downloadCargoPackage now unpacks and installs from a fresh directory, avoiding having build environment files (like env-vars) appearing in the output

0.17.0 - 2024-05-18

Added

• cargoDoc now supports docInstallRoot to influence which directory will be installed to $out/share (which can be useful when cross-compiling). By default $CARGO_TARGET_DIR and $CARGO_BUILD_TARGET (if set) will be taken into account
• crateNameFromCargoToml now supports selecting a derivation name by setting package.metadata.crane.name or workspace.metadata.crane.name in the root Cargo.toml
• vendorCargoDeps, vendorCargoRegistries, vendorGitDeps, and vendorMultipleCargoDeps now support arbitrary overrides (i.e. patching) at the individual crate/repo level when vendoring sources.

Changed

• Breaking cargoAudit no longer accepts cargoExtraArgs (since it does not support the regular set of cargo flags like most cargo-commands do, it does not make much sense to propagate those flags through)
• buildTrunkPackage now sets env.TRUNK_SKIP_VERSION_CHECK = "true"; if not specified

Deprecations

• In the future, crateNameFromCargoToml will stop considering workspace.package.name in the root Cargo.toml when determining the crate name. This attribute is not recognized by cargo (which will emit its own warnings about it) and should be avoided going forward.
• In the future, crane.lib.${system} will be removed. Please switch to using (crane.mkLib nixpkgs.lib.${system}) as an equivalent alternative.

0.16.6 - 2024-05-04

Fixed

• Same as 0.16.5 but with the correct tag deployed to Flakestry/FlakeHub

0.16.5 - 2024-05-04

Fixed

• Workspace inheritance for git dependencies now ignores (removes) all comments around dependency declarations to work around a mangling bug in toml_edit (see https://github.com/ipetkov/crane/issues/527 and https://github.com/toml-rs/toml/issues/691)

0.16.4 - 2024-04-07

Added

• Added a warning if an unsupported version of nixpkgs is used

Changed

• cargoNextest now supports setting withLlvmCov which will automatically run cargo llvm-cov nextest. Note that withLlvmCov = true; is (currently) only supported when partitions = 1;

Fixed

• inheritCargoArtifactsHook and installCargoArtifactsHook now correctly handle the case when CARGO_TARGET_DIR is set to a nested directory
• Dependency vendoring now correctly takes unused patch dependencies into account

0.16.3 - 2024-03-19

Changed

• Sources are now fetched crates.io's CDN, following cargo's (new) default behavior.

Fixed

• vendorMultipleCargoDeps correctly lists registries as an optional parameter

0.16.2 - 2024-02-21

Changed

• cleanCargoToml now also strips out [lints] and [workspace.lints] definitions. This means avoiding unnecessarily rebuilding dependencies when the lint definitions change, and it avoids issues with failing to build dummified sources which might have violated a lint marked as deny or forbid

Fixed

• Fixed an edge case with inheriting workspace dependencies where the workspace dependency is a string (e.g. foo = "0.1.2") but the crate definition is a table (e.g. foo = { workspace = true, optional = true })

0.16.1 - 2024-01-28

Changed

• buildDepsOnly now ignores any outputs (besides the default out)

Fixed

• buildDepsOnly no longer fails when workspace is configured with #[deny(unused-extern-crates)]
• vendorCargoDeps (and friends) are now much more friendly to cross-compilation definitions. Specifically, source vendoring will always build dependencies to run on the build machine (and not for the host we're cross compiling to).

0.16.0 - 2024-01-18

Changed

• Breaking: dropped compatibility for Nix versions below 2.18.1
• Breaking: dropped compatibility for nixpkgs-23.05.
• buildTrunkPackage has a new argument, wasm-bindgen-cli must be set to avoid mismatching versions between the wasm-bindgen library and CLI tool.

Fixed

• Workspace inheritance of lints in git dependencies is now correctly handled

0.15.1 - 2023-11-30

Changed

• buildDepsOnly will now assume cargoTestExtraArgs = "--no-run"; if not specified (since there is no point to trying to run tests with the stripped sources). To get the old behavior back, set cargoTestExtraArgs = "";

Fixed

• buildTrunkPackage's preConfigure script to fail quicker with a more obvious error message if dependencies at not appropriately met

0.15.0 - 2023-11-05

Added

• cargoDeny added for running cargo-deny.
• installCargoArtifactsHook will now pass along the contents of $zstdCompressionExtraArgs as arguments to zstd when compressing artifacts. This allows for tailoring compression behavior, for example, by setting zstdCompressionExtraArgs = "-19"; on the derivation.

Changed

• The use-zstd artifact installation mode now uses a chained, incremental approach to avoid redundancy. Old behavior (taking a full snapshot of the cargo artifacts) can be achieved by setting doCompressAndInstallFullArchive = true.
• The default installCargoArtifactsMode has been changed to use-zstd, meaning cargo artifacts will be compressed to a series of incremental, zstd compressed tarballs across derivations. To get the old behavior back, set installCargoArtifactsMode = "use-symlink" to any derivation which produces cargo artifacts.
• All dependencies (outside of nixpkgs) have been dropped from the (main) flake.lock file so they do not pollute downstream projects' lock files.

Fixed

• mkDummySrc now properly handles file cleaning (and file including) when a build is invoked with a --store ... override

0.14.3 - 2023-10-17

Changed

• craneUtils will now be built with the rustPlatform provided by nixpkgs instead of the currently configured toolchain. This should hopefully result in fewer surprises for those testing with really old MSRV toolchains.
• devShell will now additionally include clippy and rustfmt from the currently configured toolchain

Fixed

• replaceCargoLockHook now runs as a prePatch hook (rather than postUnpack) which correctly replaces the Cargo.lock in the source directory rather than the parent directory

0.14.2 - 2023-10-15

Added

• replaceCargoLockHook can now be used to easily replace or insert a Cargo.lock file in the current derivation

Changed

• cargoAudit will pass --ignore yanked by default if cargoAuditExtraArgs are not specified. This is because cargo-audit cannot check for yanked crates from inside of the sandbox. To get the old behavior back, set cargoAuditExtraArgs = "";.

Fixed

• Fixed handling of Cargo workspace inheritance for git-dependencies where said crate relies on reading non-TOML metadata (i.e. comments) from its Cargo.toml at build time. (#407)
• Fixed handling of dummy target names to avoid issues with cargo doc. (#410)
• When using installCargoArtifactsMode = "use-zstd"; all files will be marked as user-writable while compressing
• removeReferencesToVendoredSources now signs aarch64-darwin binaries. (#418)

0.14.1 - 2023-09-23

Fixed

• Fixed a bug where buildPackage would fail to inherit artifacts from dependency crates if cargoArtifacts was not explicitly specified.

0.14.0 - 2023-09-21

Added

• Added devShell, a thin wrapper around pkgs.mkShell which automatically provides cargo and rustc.
• Added the ability to specify output hashes of git dependencies for fully offline evaluations. The outputHashes attribute can now be optionally specified in vendorCargoDeps, vendorGitDeps, vendorMultipleCargoDeps, or anything else which delegates to them.

Changed

• Breaking (technically): buildDepsOnly, buildPackage, cargoBuild, cargoClippy, cargoDoc, cargoLlvmCov, and cargoTest's defaults have been changed such that if cargoExtraArgs have not been set, a default value of --locked will be used. This ensures that a project's committed Cargo.lock is exactly what is expected (without implicit changes at build time) but this may end up rejecting builds which were previously passing. To get the old behavior back, set cargoExtraArgs = "";
• Breaking: cargoDoc will no longer install cargo artifacts by default. Set doInstallCargoArtifacts = true; to get the old behavior back.
• cargoDoc will now install generated documentation in $out/share/doc
• Fixed a bug when testing proc macro crates with cargoNextest on macOS. (#376)
• Replaced various internal usages of runCommandLocal with runCommand for more optimal behavior when downloading cached artifacts

0.13.1 - 2023-08-22

Changed

• buildTrunkPackage will now use dart-sass instead of nodePackages.sass
• Vendoring git dependencies will now always resolve symlinks inside of a crate's directory. This allows for symlinks inside of a crate's directory to possibly refer to files at the root of the git repo itself (via symlink) and have those contents preserved during vendoring.

0.13.0 - 2023-08-07

Added

• buildPackage now supports installing dylib targets
• Added support for sparse registries

Changed

• Breaking: dropped compatibility for Nix versions below 2.13.3
• Breaking: dropped compatibility for nixpkgs-22.05. nixpkgs-23.05 and
• Breaking (technically): if buildPackage is called without setting cargoArtifacts, the default buildDepsOnly invocation will now stop running any installation hooks
• Breaking (technically): buildPackage no longer installs cargo binary dependencies (i.e. when the bindeps feature is used) by default
• inheritCargoArtifactsHook will now symlink dependency .rlib and .rmeta files. This means that derivations which reuse existing cargo artifacts will run faster as fewer files (and bytes!) need to be copied around. To disable this behavior, set doNotLinkInheritedArtifacts = true;.
• cargoTarpaulin will now set doNotLinkInheritedArtifacts = true; unless otherwise specified
• Update crane-utils dependencies for successful build in nightly Rust (2023-06-28)

0.12.2 - 2023-06-06

Added

• Added support for the Trunk wasm app build tool

Changed

• resolver key is no longer cleaned from Cargo.toml

Fixed

• buildTrunkPackage will now strip references to store files by default
• buildTrunkPackage will now set the right wasm-opt version

0.12.1 - 2023-04-10

Changed

• Breaking: When setting a default value for cargoArtifacts, buildPackage will now ignore installPhase and installPhaseCommand when calling buildPackage. To bring back the old behavior, please specify cargoArtifacts explicitly

Added

• vendorMultipleCargoDeps can now be used to vendor crates from multiple distinct Cargo.lock files. Notably this allows for building the standard library (via -Z build-std or equivalent) since both the project's and the Rust toolchain's Cargo.lock files can be vendored together

Changed

• vendorCargoRegistries now accepts a registries parameter from the caller. If not specified, it will be computed via cargoConfigs. Also cargoConfigs is now an optional parameter which will default to [] if not specified.

Fixed

• vendorCargoDeps correctly accepts arguments which have not set src, so long as one of cargoLock, cargoLockContents, or cargoLockParsed is set

0.12.0 - 2023-03-19

Added

• Add a stubbed binary target to each "dummy" crate generated to support "artifact dependencies" nightly feature in case a crate is used as bin artifact dependency.
• Add cargoLlvmCov to run cargo llvm-cov
• Add cargoLockParsed option to vendorCargoDeps to support Cargo.lock files parsed as nix attribute sets.
• craneLib.path can now be used as a convenience wrapper on (or drop in replacement of) builtins.path to ensure reproducible results whenever paths like ./. or ./.. are used directly.

Changed

• Breaking (technically): mkCargoDerivation will remove the following attributes before lowering to mkDerivation: cargoLock, cargoLockContents and cargoLockParsed. If your derivation needs these values to be present they can be explicitly passed through via .overrideAttrs buildDepsOnly as dummySrc will take priority
• The API docs have been updated to refer to craneLib (instead of just lib) to avoid ambiguities with pkgs.lib.
• cargo is now invoked with --release when $CARGO_PROFILE == release instead of passing in --profile release to better support tools which do not understand the latter

Fixed

• Fixed support for projects depending on crates utilising per-target workspace dependencies.

0.11.3 - 2023-02-19

Fixed

• Fixed an unintentional cache invalidation whenever buildDepsOnly would run on an unfiltered source (like src = ./.;).

Changed

• A warning will now be emitted if a derivation's pname or version attributes are not set and the value cannot be loaded from the derivation's root Cargo.toml. To resolve it consider setting pname = "..."; or version = "..."; explicitly on the derivation.
• A warning will now be emitted if src and dummySrc are passed to buildDepsOnly as dummySrc will take priority

0.11.2 - 2023-02-11

Fixed

• buildPackage is more tolerant of misbehaving proc macros which write to stdout during the build

0.11.1 - 2023-01-21

Changed

• Documented and made it easier to build a cargo workspace located in a subdirectory of the source root

Fixed

• Previously compiled build scripts now maintain their executable bit when inherited
• Workspace inheritance in git dependencies is now correctly handled

0.11.0 - 2022-12-26

Added

• Documentation is now available at crane.dev

Changed

• Breaking: dropped compatibility for Nix versions below 2.11.0
• Breaking: dropped compatibility for nixpkgs-22.05. nixpkgs-22.11 and nixpkgs-unstable are fully supported
• Zstd compression of cargo artifacts now defaults to using as many cores as $NIX_BUILD_CORES allows for (or all available cores if it isn't defined)
• Dummy sources now attempt to use the same name as their original source (minus the Nix store path and hash) to minimize errors with build scripts which expect their full path to not change between runs

0.10.0 - 2022-12-01

Added

• A new installation mode has been defined which symlinks identical cargo artifacts against previously generated ones. This allows for linear space usage in the Nix store across many chained derivations (as opposed to using a zstd compressed tarball which uses quadratic space across many chained derivations).
• mkDummySrc optionally accepts a dummyrs argument which allows for customizing the contents of the dummy Rust files that will be generated.

Changed

• Breaking: all cargo-based derivations will now default to using symlinking their installed artifacts together instead of using zstd compressed tarballs. To get the old behavior back, set installCargoArtifactsMode = "use-zstd"; in the derivation.
  • Note that buildPackage will continue to use zstd compressed tarballs while building dependencies (unless either of cargoArtifacts or installCargoArtifactsMode is defined, in which case they will be honored)
• Breaking: the format for defining crate registries has been changed: each registry URL should map to a set containing a downloadUrl attribute. This set may also define fetchurlExtraArgs (another set) which will be forwarded to the fetchurl invocations for crates for that registry.
• Breaking (technically): buildDepsOnly will now only default to running cargo check with the --all-targets flag only if doCheck = true; is set on the derivation (otherwise the flag is omitted). To get the previous behavior back simply set cargoCheckExtraArgs = "--all-targets";.
• registryFromGitIndex now uses shallow checkouts for better performance
• registryFromDownloadUrl and registryFromGitIndex now allow specifying fetchurlExtraArgs which will be forwarded to the fetchurl invocations for crates for that registry

Fixed

• Unpacking a git repository now ignores duplicate crates to match cargo's behavior
• Sped up stripping references to source files
• Dummy sources now import the core crate more robustly (playing more nicely with cargo-hakari)
• Building a crate's dependencies automatically works for uefi targets

0.9.0 - 2022-10-29

Changed

• Breaking: all setup hooks have been removed from the packages flake output. They can still be accessed via the lib flake output.
• Breaking: cargoBuild now only runs cargo build in a workspace, tests are no longer run
• Breaking: buildDepsOnly does not automatically imply the --all-targets flag when invoking cargo check. Use cargoCheckExtraArgs to control this
• buildDepsOnly now accepts cargoCheckExtraArgs for passing additional arguments just to the cargo check invocation. By default --all-targets will be used
• buildDepsOnly now accepts cargoTestExtraArgs for passing additional arguments just to the cargo test invocation
• buildPackage now delegates to mkCargoDerivation instead of cargoBuild

Fixed

• crateNameFromCargoToml now takes workspace inheritance into account. If a crate does not specify package.version in its (root) Cargo.toml but does specify workspace.package.version then the latter will be returned.
• Freestanding (#![no_std]) targets are now supported

0.8.0 - 2022-10-09

Added

• cargoTest can now be used for only running the tests of a workspace

Changed

• Breaking (technically): build hooks now expect helper tools (like cargo, jq, zstd, etc.) to be present on the path instead of substituting a reference to a (possibly different) executable in the store.
• mkCargoDerivation now automatically vendors dependencies if cargoVendorDir is not defined
• mkCargoDerivation now automatically populates pname and version (via crateNameFromCargoToml) if they are not specified
• mkCargoDerivation now defaults to an empty checkPhaseCargoCommand if not specified
• cargoAudit now delegates to mkCargoDerivation instead of cargoBuild
• cargoClippy now delegates to mkCargoDerivation instead of cargoBuild
• cargoDoc now delegates to mkCargoDerivation instead of cargoBuild
• cargoFmt now delegates to mkCargoDerivation instead of cargoBuild
• cargoNextest now delegates to mkCargoDerivation instead of cargoBuild
• cargoTarpaulin now delegates to mkCargoDerivation instead of cargoBuild

Fixed

• Installing binaries now uses the same version of cargo as was used to build the package (instead of using whatever version is present in nixpkgs)

Deprecated

• The packages flake output has been deprecated. All setup hooks can be accessed via the lib flake output (or via the result of the mkLib flake output)

0.7.0 - 2022-09-28

Added

• cargoDoc can now be used for building the documentation of a workspace
• cleanCargoSource can now be used to filter sources to only include cargo and Rust files (and avoid rebuilds when irrelevant files change). filterCargoSources is the underlying filter implementation and can be composed with other filters
• removeReferencesToVendoredSourcesHook defines a post-install hook which will remove any references to vendored sources from any installed binaries. Useful for preventing nix from considering the binaries as having a (runtime) dependency on said sources

Changed

• Breaking: mkCargoDerivation now includes a default configurePhase which does nothing but run the preConfigure and postConfigure hooks. This is done to avoid breaking builds by including puts happen to have setup-hooks which try to claim the configure phase (such as cmake). To get the old behavior back, set configurePhase = null; in the derivation.
• mkCargoDerivation (along with any of its callers like cargoBuild, buildPackage, etc.) now accept a stdenv argument which will override the default environment (coming from pkgs.stdenv) for that particular derivation
• mkDummySrc now accepts extraScript which can be used to run a custom script, and therefore customize what the dummy source contains
• buildDepsOnly now accepts dummySrc as a way to directly pass in the dummy source to be used. Automatically derived via args.src if not specified.

Fixed

• cargoAudit properly keeps any audit.toml files when cleaning the source
• buildPackage now has more robust checks to ensure that all references to vendored sources are removed after installation (which avoids consumers of the final binaries having to download the sources as well)
• mkDummySrc how handles build scripts in a manner which ensures cargo runs the real script later (instead of thinking it has not changed)

0.6.0 - 2022-09-07

Added

• Added cargoNextest for running tests via cargo-nextest
• Added cargoAudit for running cargo-audit with a provided advisory database instance.

Changed

• Breaking: the --workspace flag is no longer set for all cargo commands by default. The previous behavior can be recovered by setting cargoExtraArgs = "--workspace"; in any derivation.
• Breaking: the $CARGO_PROFILE environment variable can be used to specify which cargo-profile all invocations use (by default release will be used). Technically breaking if the default command was overridden for any derivation; set CARGO_PROFILE = ""; to avoid telling cargo to use a release build.
• Breaking: cargoTarpaulin will use the release profile by default
• Breaking: cargoClippy's cargoClippyExtraArgs now default to "--all-targets" instead of being specified as the cargo command itself. If you have set cargoClippyExtraArgs to an explicit value and wish to retain the previous behavior you should prepend "--all-targets" to it.
• Breaking: remapSourcePathPrefixHook and the doRemapSourcePathPrefix option have been removed, and the behavior of buildPackage has been updated to break false dependencies on the crate sources from the final binaries (which was the old behavior of the doRemapSourcePathPrefix option). To disable this behavior, set the doNotRemoveReferencesToVendorDir environment variable to any non-empty string.
• All cargo invocations made during the build are automatically logged
• Vendoring git dependencies will throw a descriptive error message if a locked revision is missing from Cargo.lock and a hint towards resolution

Fixed

• Breaking: vendorGitDeps will only include crates referenced by the Cargo.lock file, meaning any extraneous crates which happen to be present in the git repository will be ignored.

0.5.1 - 2022-07-20

Added

• Added .overrideToolchain as a convenience for using a custom rust toolchain

Fixed

• Fixed an issue where mkDummySrc would produce incorrect results for filtered sources: #46

0.5.0 - 2022-06-12

Changed

• Breaking: dropped compatibility for Nix versions below 2.8.1
• Breaking: updated all flake attributes to follow the new .default guidance as per Nix's warnings. Specifically:
  • Crane's default overlay is now available at .overlays.default (previously .overlay)
  • All templates now use {app,devShells,packages}.default as well
• Breaking: lib.fromTOML and lib.toTOML have been removed in favor of builtins.fromTOML
• Improved support for consuming crane without using flakes
• The nix-std dependency has been dropped

0.4.1 - 2022-05-29

Fixed

• Dummy source derivations go to greater lengths to only depend on the files they consume. Specifying the entire flake source as an input (e.g. via buildPackage { src = self; }) now avoids rebuilding everything from scratch whenever any file is changed. #28

0.4.0 - 2022-05-10

Changed

• Breaking: the previously named utils flake input has been renamed to flake-utils
• buildDepsOnly now adds --all-targets to the default cargo check invocation. This allows caching all artifacts (including from dev-dependencies) such that tools like clippy don't have to generate them every time they run.
• Templates now use the newer flake format accepted by Nix 2.8 (e.g. {packages,overlays,devShells}.default, etc.)

Fixed

• Fixed project and template flakes to avoid superfluous follows declaration for flake-utils
• Fixed quoting of relative paths to allow building with external sources

0.3.3 - 2022-02-24

Fixed

• Use lib.groupBy if builtins.groupBy isn't available (i.e. if a Nix version earlier than 2.5 is used)
• The cross compilation example also hows how to set the HOST_CC environment variable which may be required by some build scripts to function properly

0.3.2 - 2022-02-18

Fixed

• Fixed handling git dependencies whose locked revision is not on the repository's main branch

0.3.1 - 2022-02-17

Added

• Added template and example for cross compiling to other platforms
• Added template and example for building static binaries using musl

Changed

• cargoClippy and cargoTarpaulin will install cargo artifacts by default (or install an empty target directory if there are none). This allows for more easily chaining derivations if doing so is desired.
  • This can be disabled by setting doInstallCargoArtifacts = false; in the derivation

Fixed

• Fixed an issue where cross compiling would try to needlessly cross compile rustc and cargo themselves

0.3.0 - 2022-02-11

Added

• downloadCargoPackageFromGit has been added to handle downloading and unpacking a cargo workspace from a git repository
• vendorCargoRegistries has been added to handle vendoring crates from all registries used in a Cargo.lock file
• vendorGitDeps has been added to handle vendoring crates from all git sources used in a Cargo.lock file

Changed

• vendorCargoDeps now automatically handles git dependencies by default
  • Git dependencies will be vendored as another source in the output derivation
  • The cargo configuration is done such that the sources are available to use when it decides, without overriding that crate for the entire workspace
    • For example, if your workspace contains a crate only used for testing which has a git dependency of a crate used by other parts of the workspace, then only that crate will use the git dependency. The rest of the workspace will continue to use the crates.io version, just like cargo behaves when used outside of Nix.

0.2.1 - 2022-02-11

Changed

• cargoFmt will install cargo artifacts by default (or install an empty target directory if there are none). This allows for more easily chaining derivations if doing so is desired.
  • This can be disabled by setting doInstallCargoArtifacts = false; in the derivation

0.2.0 - 2022-01-30

Added

• Support for alternative cargo registries

Changed

• urlForCargoPackage now takes configured registries into account when downloading crate sources
• Breaking: vendorCargoDeps now vendors each unique registry as a subdirectory within the derivation's output. A config.toml file is also placed at the output root which contains the necessary configurations to point cargo at the vendored sources.
• configureCargoVendoredDepsHook is now aware of the updated vendorCargoDeps output format, and will use the config.toml file it generates if it is present. Otherwise it will fall back to the previous behavior (which is treat the entire directory as only vendoring crates.io).
• Source vendoring now uses runCommandLocal (instead of runCommand) to reduce network pressure in trying to fetch results which can quickly be built locally
• Searching for Cargo.toml or .cargo/config.toml files is now done more efficiently
