| ## 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. |
