filterAttrs is going through all of them I think, but try removeAttrs (or something similar).
I'm not sure, but probably you want to remove those before importing (or rather before evaluation), right? so probably you need to do something like module = import ./my-module; module` = removeAttrs..... imports = [ module` ]; but I've not tried this, just my guess. 2016-09-07 11:12 GMT+01:00 Rickard Nilsson <[email protected]>: > On 09/07/2016 11:54 AM, 4levels wrote: > >> Hi Rickard, >> >> All I can think of currently is that you could create a new config >> variable using filterAttrs to keep only the information you need. >> Not sure if this solves your question though as I'm not aware if you can >> use another variable in your scenario. >> > > Using filterAttrs like this would introduce an infinite recursion, I think: > > config = { > myattrs = filterAttrs (k: _: k != "a") config.myattrs; > } > > But maybe that wasn't what you had in mind. > > For the issue that spurred this question I have now added an "enable" > option for the attributes, see: https://github.com/NixOS/nixpk > gs/pull/18391 > > However, that is not a general solution to this problem, so any further > hints are welcome. > > / Rickard > > > Kind regards, >> >> Erik >> >> On Wed, Sep 7, 2016 at 12:35 AM Rickard Nilsson >> <[email protected] <mailto:[email protected]>> wrote: >> >> Is it possible to unset an attrsOf option?
