Tools for processing the Dart SDK

patch_sdk.dart

This script combines:

tool/input_sdk/lib/...
tool/input_sdk/patch/...
tool/input_sdk/private/...

and produces the merged SDK sources in:

tool/generated_sdk/...

The result has all "external" keywords replaced with the @patch implementations.

Generally local edits should be to input_sdk/patch and input_sdk/private, as those two directories are specific to DDC. input_sdk/lib should represent unmodified SDK sources to the maximum extent possible. Currently there are slight edits to the type annotations in some cases.

See patch_sdk.dart for more information.

sdk_version_check.dart

Asserts that the Dart VM is at least a particular semantic version. It returns an exit code to make it easy to integrate with shell scripts.
