Member Data Documentation

◆ assigned

std::set<std::string> fsw::script::anonymous_namespace{Parser.cpp}::Parser::assigned

Variables assigned somewhere at or before the current point, for use-before-assign.

Deliberately flow-insensitive: a variable first assigned inside an if counts as assigned afterwards. Being stricter would reject readable scripts; being looser would let a NaN reach a comparison that decides whether a valve opens.
