What's Changed

This release prioritizes enhancing the functionality of 'select' expressions within the Nix language. For instance, improvements have been made to lib.mkDefault, pkgs.nixd, and similar components.

Unlike previous configuration-based approach in nixd 1.0, these features will work out of box for you.

New Features

• nixd: lib + pkgs completion with "select", e.g. lib.gen|, pkgs.stdenv.mkDerivat| by @inclyc in #544

• nixd/Controller: support select in nested with expression by @inclyc in #546

with pkgs; [ nixd.over| ]

Enables auto-completion for variables that comes from with expression and "select" into nested attrs.

e.g.

• nixd/Controller: support "goto definition" for select expressions by @inclyc in #549

Add "goto definition" support for select expressions, e.g.

with pkgs; [
  nixVersions.nix
#              ^
]

pkgs.stdenv.mkDerivation
#            ^

These values are now "Ctrl + Click"-able to nixpkgs locations.

Bug Fixes

• nixd: don't pass NIX_PATH to nixd-attrset-eval unit tests by @inclyc in #542
• nixd/Controller: fix crashing on empty selector idiom in completion by @inclyc in #553

Other Changes

• libnixf: generate diagnostic declarations from python by @inclyc in #548
• nixd/Eval: basic support for value metadata by @inclyc in #545
• nixd/test/completion: precommit pkgs failing test by @inclyc in #550
