scarb cairo-run

The scarb cairo-run command executes the main function of a local package. Scarb comes with preinstalled cairo-run extension, which bundles the Cairo's native runner. The package needs to be compiled with scarb build beforehand.

Our examples in the repository now includes a package with the main function, and you can check out this feature by quickly running scarb cairo-run over it:

$ cd examples/cairo_run_example
$ scarb build
$ scarb cairo-run --available-gas 2000000
running cairo_run_example ...
Run completed successfully, returning [2]
Remaining gas: 1971340

For more information, check out the dedicated Cairo run documentation page.
