| description | Search for Nix packages using the nix-search CLI tool |
Search for Nix packages using the nix-search CLI tool, which queries https://search.nixos.org. Supports filtering by name, version, programs, channel, and ElasticSearch QueryString syntax. Wildcards (*, ?) are supported; regex is not.
Prerequisites: nix-search in PATH — https://github.com/peterldowns/nix-search-cli
Tip: Use this before adding packages with the home-manager-add-packages skill to verify package names.
