| /** |
| * Options that affect the semantics of Bazel's build language. |
| * |
| * <p>These are injected into Skyframe (as an instance of {@link StarlarkSemantics}) when a new |
| * build invocation occurs. Changing these options between builds will therefore trigger a |
| * reevaluation of everything that depends on the Starlark interpreter — in particular, |
| * evaluation of all BUILD and .bzl files. |
| * |
| * <p><em>To add a new option, update the following:</em> |
| * |
| * <ul> |
| * <li>Add a new {@code @Option}-annotated field to this class. The field name and default value |
| * should be the same as in {@link StarlarkSemantics}, and the option name in the annotation |
| * should be that name written in snake_case. Add a line to set the new field in {@link |
| * #toStarlarkSemantics}. |
| * <li>Define a new {@code StarlarkSemantics.Key} or {@code StarlarkSemantics} boolean flag |
| * identifier. |
| * <li>Add a line to set the new field in both {@link ConsistencyTest#buildRandomOptions} and |
| * {@link ConsistencyTest#buildRandomSemantics}. |
| * <li>Update manual documentation in site/docs/skylark/backward-compatibility.md. Also remember |
| * to update this when flipping a flag's default value. |
| * <li>Boolean semantic flags can toggle StarlarkMethod-annotated Java methods (or their |
| * parameters) on or off, making them selectively invisible to Starlark. To do this, add a new |
| * entry to {@link BuildLanguageOptions}, then specify the identifier in {@link |
| * StarlarkMethod#enableOnlyWithFlag} or {@link StarlarkMethod#disableWithFlag}. |
| * </ul> |
| * |
| * For both readability and correctness, the relative order of the options in all of these locations |
| * must be kept consistent; to make it easy we use alphabetic order. The parts that need updating |
| * are marked with the comment "<== Add new options here in alphabetic order ==>". |
