v2.6.4

Cairo release notes ➡️

Welcome to the release notes for Scarb v2.6.4!
This release introduces preliminary work on procedural macros and a new configuration flag.

An option to disable gas calculation

This release introduces a new flag in the Cairo compiler configuration, called enable-gas.

If set to false, Scarb will not add any instructions related to gas usage calculation during the project compilation. By default, this flag is set to true. This flag cannot be disabled while compiling the starknet-contract target.

[cairo]
enable-gas = false

v2.6.2

Cairo release notes ➡️

Welcome to the release notes for Scarb v2.6.2!

Fix compilation of tests with contracts in dependencies

Since Scarb does not compile tests defined in the dependencies of a tested package, all items with the #[cfg(test)] attribute are removed from all components in the compilation unit apart from the main component (i.e., the package that is tested).

This behavior implies that there cannot be any expectation in the Cairo test runner, that items defined under the #[cfg(test)] in dependencies are available to be imported during testing. Unfortunately, the implementation of test runner in recent releases of Scarb in some cases has erroneously expected one of the variables in the contract definition to be available under those circumstances. This meant that for some projects, the test runner failed to execute the test.

This quick release introduces a fix.

Warning

Welcome to the release notes for Scarb v2.6.0-rc.0!
This release comes with Sierra v1.5.0.

Changes to conditional compilation of tests.

From this release onwards, Scarb will not compile tests defined in dependencies of a tested package. All items with #[cfg(test)] attribute will be removed from all components in the compilation unit apart from the main component (i.e. the package that is tested). You can verify which cfg attributes are used in which component of your project by reviewing it's Scarb metadata. This means that compilation of tests in some projects (with a lot of thoroughly tested dependencies) will be slightly faster (as Scarb will omit some unnecessary steps). However, more importantly this means a full isolation of test dependencies. If you want to test your package, you only need to ensure that tests defined in it can be compiled (regardless of tests defined in other packages). Dependecies required by tests from a package should be defined under the dev-dependencies section, so they do not propagated to other packages that depend on the package.

v2.5.2

Cairo release notes ➡️

Welcome to the release notes for Scarb v2.5.2!

This release brings the scarb check command for the first time!

Scarb Check

If you want to check your code for any build errors, but do not really need any build artifacts, you can now use the new check command instead of standard build! This will give you a perfomance advantage, as Scarb no longer needs to spend time creating and emitting all the output files. Try this in your CI!
