I like this definition but did not find an easy way to update the values in a Nix file without doing string re...
@[email protected] , this could be really useful for advancing programmatic mutation of pre-existing nix config files using graphical installers and user administ ration tools, like with SnowflakeOS:
Wow, that’s awesome. Hopefully that can breathe some new life into SnowflakeOS! My attempts at manipulating nix code went through a nix parser that I can’t remember the name of. That’s when I found (or came up with? dunno) the importJson function. But this could be cleaner and more reviewable + definitely allows for things like function calls to take advantage of the “JSON on steroids” aspect the author mentioned.
