+ [Preferences] It should be possible to have different default values for WebKitLegacy and WebKit in preference yaml files
+ https://bugs.webkit.org/show_bug.cgi?id=216987
+
+ Reviewed by Darin Adler.
+
+ Add new syntax for default values that allows specializing based on both frontend (WebKit or
+ WebKitLegacy) and then futher based on platform macros. For example, the preference for
+ CSSTypedOMEnabled now looks like:
+
+ CSSTypedOMEnabled:
+ type: bool
+ humanReadableName: "CSS Typed OM"
+ humanReadableDescription: "Enable the CSS Typed OM"
+ webcoreBinding: RuntimeEnabledFeatures
+ condition: ENABLE(CSS_TYPED_OM)
+ defaultValue:
+ WebKitLegacy:
+ default: false
+ WebKit:
+ "ENABLE(EXPERIMENTAL_FEATURES) && (PLATFORM(GTK) || PLATFORM(WPE))": true
+ default: false
+
+ Which means that in WebKitLegacy, the default value is false, and in WebKit, the default
+ value will be:
+
+ #if ENABLE(EXPERIMENTAL_FEATURES) && (PLATFORM(GTK) || PLATFORM(WPE))
+ true
+ #else
+ false
+ #endif
+
+ As many platform macro based conditions can be provided as wanted, and they are evaluated
+ in the order specified in the file.
+
+ The syntax currently always requires explicitly specifying WebKitLegacy and WebKit and default
+ for each, even if they are all the same, but could be extended in the future to allow compaction
+ if that becomes desirable. There is also not yet support for conditionally enabling a feature
+ based on os-feature-flags or linked-on-or-after checks, so those still require specifying the
+ default value as a function, but that seems like a nice future improvement.
+
+ As this is still staging for doing this for both WebKitLegacy and WebKit, this change only effects
+ WebKitLegacy for now, and subsequent changes will move this to a shared location.
