Rudder

Allow to create files for partial overriding files of rudder-web.properties in a ".d" directory (ie rudder-web.properties.d)

Moreover, only file with the ".properties" (or .config ? .prop too ?) extension should be taken into account.

Something like that:

configuration-rudder-7.1.properties [main configuration files with default values]
configuration-rudder-7.1.properties.d
├── 10-low-override.properties [lower priority]
├── 90-high-override.properties [higher priority]
├── 99-bad-config-ext [ignored because bad extension]
└── rudder-web.properties-resolved-debug [in debug mode, produces the resolved values with origin & override info]
