Shea Levy	608110804c	Make all ExternalValueBase functions const	2014-12-02 10:27:10 -05:00
Shea Levy	320659b0cd	Allow external code using libnixexpr to add types ... Code that links to libnixexpr (e.g. plugins loaded with importNative, or nix-exec) may want to provide custom value types and operations on values of those types. For example, nix-exec is currently using sets where a custom IO value type would be more appropriate. This commit provides a generic hook for such types in the form of tExternal and the ExternalBase virtual class, which contains all functions necessary for libnixexpr's type-polymorphic functions (e.g. `showType`) to be implemented.	2014-12-02 10:27:04 -05:00
