2015-07-23Optimize small listsEelco Dolstra
The value pointers of lists with 1 or 2 elements are now stored in the list value itself. In particular, this makes the "concatMap (x: if cond then [(f x)] else [])" idiom cheaper.

2014-12-02Allow external code using libnixexpr to add typesShea Levy
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.
