| github.com/zclconf/go-cty/cty | Package cty (pronounced see-tie) provides some infrastructure for a type system that might be useful for applications that need to represent configuration values provided by the user whose types are not known at compile time, particularly if the calling application also allows such values to be used in expressions. |
