mergeAttrDefinitionsWithPrio

lib.modules.mergeAttrDefinitionsWithPrio

Docs pulled from | This Revision | 10 minutes ago

Merge an option's definitions in a way that preserves the priority of the individual attributes in the option value.

This does not account for all option semantics, such as readOnly.

Inputs

opt: 1. Function argument

Type

option -> attrsOf { highestPrio, value }

Noogle detected

Implementation

The following is the current implementation of this function.

mergeAttrDefinitionsWithPrio =
    opt:
    let
      defsByAttr = zipAttrs (
        concatLists (
          concatMap (
            { value, ... }@def:
            map (mapAttrsToList (
              k: value: {
                ${k} = def // {
                  inherit value;
                };
              }
            )) (pushDownProperties value)
          ) opt.definitionsWithLocations
        )
      );
    in
    assert opt.type.name == "attrsOf" || opt.type.name == "lazyAttrsOf";
    mapAttrs (
      k: v:
      let
        merging = mergeDefinitions (opt.loc ++ [ k ]) opt.type.nestedTypes.elemType v;
      in
      {
        value = merging.mergedValue;
        inherit (merging.defsFinal') highestPrio;
      }
    ) defsByAttr;
