Given a config value, expand mkMerge properties, and discharge any mkIf conditions. That is, this is the place where mkIf conditions are actually evaluated. The result is a list of config values. For example, ‘mkIf false x’ yields ‘[]’, ‘mkIf true x’ yields ‘[x]’, and

mkMerge [ 1 (mkIf true 2) (mkIf true (mkIf false 3)) ]

yields ‘[ 1 2 ]’.

Implementation

The following is the current implementation of this function.

dischargeProperties = def:
    if def._type or "" == "merge" then
      concatMap dischargeProperties def.contents
    else if def._type or "" == "if" then
      if isBool def.condition then
        if def.condition then
          dischargeProperties def.content
        else
          [ ]
      else
        throw "‘mkIf’ called with a non-Boolean condition"
    else
      [ def ];
