 John Ericson | If you grep for DaemonVersion I think you'll see it | 14:05:28 |
 justinrestivo | Hello! Any chance there's a spec about the different Fields provided for each ActivityType in the nix logger? Right now to answer this question I'm grepping the nix codebase for each ActivityType and looking at the arguments to the Activity::Activity constructor to infer the field types and number (if any exist). I'm wondering if there's an easier/more canonical way to do this. | 15:30:35 |
 midischwarz12 | You overlay when you want to stitch multiple overrides together or want the package that's available across your entire package set such as nixpkgs. What you're really desiring is just a single override and probably not overriding every package that consumes this package as a dependency. So an overlay would be unnecessary | 16:39:36 |

| midischwarz12 | I think overlays are often reached for a bit too early and people should take note more often that this ruins a lot of the reproducible nature of nix. Your nixpkgs will no longer be the same as everyone else's when you use an overlay | 16:41:25 |

 tavinator | ok did you mean doing something like what's described on this page? https://nixos.org/guides/nix-pills/17-nixpkgs-overriding-packages.html | 10:27:48 |
 mrdev023 | Hi everyone, i want to know what's the recommendation to work on nixpkgs. Currently, i tried to open nixpkgs project on vscode and neovim. But it's very slow because nixpkgs have a lot of folders.
Maybe open only the correct directory ? | 17:12:11 |
 K900 | Wrong room | 17:16:05 |
| K900 | You want #Nixpkgs / NixOS contributions | 17:16:14 |
| mrdev023 | thx | 17:16:40 |
| mrdev023 | I can't join it K900 .... | 17:17:15 |
| mrdev023 | My bad just a matrix bug | 17:17:44 |

| John Ericson | Robert Hensing (roberth): does nix eval override the "always trace" thing? | 20:47:57 |
 Robert Hensing (roberth) | John Ericson: The problem there is that printValue only prints the "final" line, which is quite sensible, considering that it may print many "values" that throw | 20:49:08 |
| John Ericson | Robert Hensing (roberth): this is implemented in the Printer class thing? | 20:50:38 |
| Robert Hensing (roberth) | yeah | 20:50:50 |
| John Ericson | I would hope it could be more "semantic" and not just chop an error at one line? | 20:51:11 |
| Robert Hensing (roberth) | for sure, it's the exception message without the traces | 20:51:57 |
| John Ericson | printError_ in this? | 20:52:13 |
| John Ericson | Robert Hensing (roberth): OK throwing in the towel on tracing :) | 21:01:00 |
| John Ericson | I left comments for the storing of the reason | 21:01:10 |
| John Ericson | it should be very easy | 21:01:12 |
