Noogle

Noogle is a Nix API search engine. It allows you to search functions based on their types and other attributes in nix projects. In nixpkgs especially the builtins and lib attributes.

Beginners-friendly search for nix and nix-related functions
Expert search with directly typing type signatures
Search functions based on:
- type
- signature
- name
tree-search from one type to another

How it works

The idea is to use a fork of nixdocto generate json data from all functions. That have the Type field which is currently supported from nixdoc.

We need your help / what is missing

Parsing Types: into a real type signature tree
Upstream missing type informations (like in /lib/attrsets.nix)
Write type signatures for the builtins in json
Add path, where each function can be imported from. e.g. lib.makeOverridable or lib.customisation.makeOverridable (it is available in both sets)
Website
- Make sure functions with missing type signatures can be found too
- Add filter by tags e.g. lib.lists
- Mobile optimization for reading on the go
Clean up / enhance my nixdoc fork.
- Make the sloppy parser more error resistant
- Some valueable information can be used from the rnix AST ?
