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:
gen/patched_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.
