lib.mkOverride

Labels a definition with a priority. See the documentation of filterOverrides for the interpretation of the priority value. Nesting this function usually leads to an invalid definition. mkDefault, mkOptionDefault, and mkForce partially apply mkOverride with common priorities used in the NixOS module system.

Inputs

priority

A numeric value representing the precedence. See the documentation of filterOverrides for the interpretation of this value.

content

The definition to be labeled with a given priority.

Examples

mkOverride 1000 "hello, world!"
=> { _type = "override"; content = "hello, world!"; priority = 1000; }

(lib.evalModules {
  modules = [
    { options.foo = lib.mkOption { }; }
    { config.foo = lib.mkOverride 20 1; }
    { config.foo = lib.mkOverride 10 2; }
  ];
}).config
=> { foo = 2; }
