Standardization of string substitutions
There are several cases in ParaView where strings are substituted for runtime values. Currently, however, there is no standard form for specifying these substitutions and various components follow their own pattern inconsistently. This task involves developing a framework for supporting string substitutions across the application. The implementation may introduce third-party libraries such as fmt for improved string formatting. The proposal aims to support named and well- documented namespaces that make it easier for users to be aware of available string substitution keywords within any given context.
