Hsjobeki: Noogle.dev - nix function exploring

Noogle.dev - nix function exploring

New page

= Noogle =

Noogle is a community maintained search page designed specifically for NixOS users and maintainers. It knows about all standard nix functions. Which are typically used via <code>builtins</code>, <code>lib</code> and the <code>pkgs</code> attributes.

== Discoverability ==

The indexing of functions is done via tree-traversal of the nix attribute sets.
Nix's position tracking is used in conjunction with static analysis based on the rnix AST to backtrace each function to its declaration in the source code.

Documentation content stems from doc-comments or from the <code>builtins</code> c++ documentation in nix in case it is a builtins function or an alias to a builtins function.

All the documentation content is essentially the same as in the {{Nixpkgs Manual}}. The difference is that noogle contains all functions, where the {{Nixpkgs Manual}} only contains parts of <code>lib</code>.

== Aliases ==

Noogle uses internal function characteristics and properties of the nix evaluator to detect aliases.

For example: <code>lib.lists.concatLists</code> is the same as calling <code>lib.concatLists</code> or <code> builtins.concatLists</code>

== Updates ==

Noogle is updated daily against the master branch of nix (builtins) and nixpkgs (lib,pkgs,...)
