Eelco Dolstra	c0a7b84748	nix path-info: Add --json flag ... Also, factor out JSON generation from value-to-json.{cc,hh}, and support producing indented JSON.	2016-08-29 17:29:24 +02:00

Eelco Dolstra	b83801f8b3	Optimize small lists ... 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.	2015-07-23 22:05:09 +02:00

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
