# Release X.Y (202?-??-??)

* `nix repl` has a new build-'n-link (`:bl`) command that builds a derivation
  while creating GC root symlinks.

* The path produced by `builtins.toFile` is now allowed to be imported or read
  even with restricted evaluation. Note that this will not work with a
  read-only store.

nix repl: make symlinks with the :bl command Requested by ppepino on the Matrix: https://matrix.to/#/!KqkRjyTEzAGRiZFBYT:nixos.org/$Tb32BS3rVE2BSULAX4sPm0h6CDewX2hClOTGzTC7gwM?via=nixos.org&via=matrix.org&via=nixos.dev This adds a new command, :bl, which works like :b but also creates a GC root symlink to the various derivation outputs. ckie@cookiemonster ~/git/nix -> ./outputs/out/bin/nix repl Welcome to Nix 2.6.0.

fix: builtins.toFile adds path to allowedPaths The produced path is then allowed be imported or utilized elsewhere: ``` assert (43 == import (builtins.toFile "source" "43")); "good" ``` This will still fail on write-only stores. 2022-04-21 20:41:37 +00:00
