2022-08-22JSON: print paths as strings without copying them to the storeNaïm Favier
Makes `printValueAsJSON` not copy paths to the store for `nix eval --json`, `nix-instantiate --eval --json` and `nix-env --json`. Fixes https://github.com/NixOS/nix/issues/5612
2022-04-21replace most Pos objects/ptrs with indexes into a position tablepennae
Pos objects are somewhat wasteful as they duplicate the origin file name and input type for each object. on files that produce more than one Pos when parsed this a sizeable waste of memory (one pointer per Pos). the same goes for ptr<Pos> on 64 bit machines: parsing enough source to require 8 bytes to locate a position would need at least 8GB of input and 64GB of expression memory. it's not likely that we'll hit that any time soon, so we can use a uint32_t index to locate positions instead.
2021-10-25toJSON: report error position for fancier outputShay Bergmann
Given flake: ```nix { description = "nix json error provenance"; inputs = {}; outputs = { self }: { jsonFunction = _: "function"; json = builtins.toJSON (_: "function"); }; } ``` - Before: ```console ❯ nix eval --json .#jsonFunction error: cannot convert a function to JSON ``` - After: ```console ❯ nix eval --json .#jsonFunction error: cannot convert a function to JSON at /nix/store/b7imf1c2j4jnkg3ys7fsfbj02s5j0i4f-source/testflake/flake.nix:4:5: 3| outputs = { self }: { 4| jsonFunction = _: "function"; | ^ 5| json = builtins.toJSON (_: "function"); ```
