| // http://dev.chromium.org/blink/runtime-enabled-features |
| // |
| // This list is used to generate RuntimeEnabledFeatures.h/cpp which contains |
| // a class that stores static enablers for all experimental features. |
| // |
| // Each feature can be assigned a "status": |
| // status=stable -> Enable this in all Blink configurations. We are committed to these APIs indefinitely. |
| // status=experimental -> In-progress features, Web Developers might play with, but are not on by default in stable. |
| // status=test -> Enabled in ContentShell for testing, otherwise off. |
| // Features without a status are not enabled anywhere by default. |
| // |
| // "implied_by" or "depends_on" specifies relationship to other features: |
| // implied_by=feature1[,feature2,...] -> The feature is automatically enabled if any implied_by features is enabled; |
| // depends_on=feature1[,feature2,...] -> The feature is enabled only if all depends_on features are enabled. |
| // Only one of "implied_by" and "depends_on" can be specified. |
| // |
| // "stable" features listed here should be rare, as anything which we've shipped stable |
| // can have its runtime flag removed soon after. |
| // |
| // origin_trial_feature_name=FEATURE_NAME is used to integrate the feature with |
| // the Origin Trials framework. The framework allows the feature to be enabled |
| // at runtime on a per-page basis through a signed token for the corresponding |
| // feature name. Declaring the origin_trial_feature_name will cause a static |
| // method to be generated in OriginTrials.h/cpp. This static method allows the |
| // feature implementation to check if it is enabled for the current context. |
| // |
| // settable_from_internals specifies whether a feature can be set from internals.runtimeFlags, with the default |
| // being false. |
