Rsyslog supports expressions at a growing number of places. So far, they are supported for filtering messages.
Expression support is provided by RainerScript. For now, please see the formal expression definition in RainerScript ABNF. It is the "expr" node.
C-like comments (/* some comment */) are supported inside the expression, but not yet in the rest of the configuration file.
