Synopsis: mkProfileAttrs _path_
|
|
|
|
Recursively collect the subdirs of _path_ containing a default.nix into attrs.
|
|
This sets a contract, eliminating ambiguity for _default.nix_ living under the
|
|
profile directory.
|
|
|
|
Example:
|
|
let profiles = mkProfileAttrs ./profiles; in
|
|
assert profiles ? core.default; 0
|
|
**/
