Introduce MemoryInputAccessor and use it for corepkgs MemoryInputAccessor is an in-memory virtual filesystem that returns files like <nix/fetchurl.nix>. This removes the need for special hacks to handle those files. 2023-10-18 18:34:58 +03:00			`#include "input-accessor.hh"`
Combine `AbstractPos`, `PosAdapter`, and `Pos` Also move `SourcePath` into `libutil`. These changes allow `error.hh` and `error.cc` to access source path and position information, which we can use to produce better error messages (for example, we could consider omitting filenames when two or more consecutive stack frames originate from the same file). 2023-12-18 23:14:42 +02:00			`#include "source-path.hh"`
