## This file contains a tweak of flake-parts's `mkFlake` function to splice in
|
|
## sources taken from npins.
|
|
|
|
## NOTE: Much of the logic in this file feels like it should be not super
|
|
## specific to fediversity. Could it make sense to extract the core of this to
|
|
## another place it feels closer to in spirit, such as @fricklerhandwerk's
|
|
## flake-inputs (which this code already depends on anyway, and which already
|
|
## contained two distinct helpers for migrating away from flakes)? cf
|
|
## https://git.fediversity.eu/Fediversity/Fediversity/pulls/447#issuecomment-8671
