 void | hi there, I am trying to move from morph to colmena, having some trouble | 00:13:27 |
| void | its always the same trouble with these tools, i want to access nodes inside modules yet fail. | 00:13:46 |
| void | is nodes always provided cos in one of my modules if I define {pkgs, config, options, lib, nodes, ...}: I get attribute nodes missing. | 00:14:42 |
| void | prolly Im doing something wrong. | 00:15:23 |
| void | tried config._module.args.nodes still no luck ;( | 00:17:28 |
| void | it is maybe the case where I need to pass the args manually since this module is buried deep inside a config with imports = [ (import ./some-module) ]; | 00:18:59 |
 Zhaofeng Li | It should be present. Just making sure: It's not a submodule, right? | 00:28:40 |
| void | it is a chain of modules imported by import = [ some-module.nix ]; | 00:32:01 |
| void | basically it is a module that scans all other hosts in nodes to get a list and do something else with data from their configs. | 00:33:46 |
| void | data is similar to config.networking.hostName etc. | 00:34:11 |
| void | not sure what the problem is. | 00:34:26 |

| 00:36:41 |
| void | I did tackle the problem in morph by re-evalling as in the following: | 00:38:51 |
| void |
_coreMachines = import "${super.morph.lib}/eval-machines.nix" {
networkExpr = ../../network.nix;
};
coreMachines = if config._module.args ? nodes
then config._module.args.nodes
else _coreMachines.nodes;
| 00:39:16 |
| void | but I bet there is a better soln. | 00:39:34 |
| void | hmm, it seems to be triggered by a call from a container config imported by containers.some-container = { .. config = {config, pkgs, lib, ...}: { .. } } | 00:59:10 |
| void | in the container config, nodes is missing. | 00:59:28 |
| void | OK, fixed. | 01:16:33 |
| void | added _module.args.nodes = nodes; in container configs. prolly nobody is gonna hit that anyways. | 01:16:53 |
| void | thnx. | 01:16:55 |
| Zhaofeng Li | Yeah, containers are evaluated in a separate evalConfig | 01:22:27 |
| void | this actually tells me nodes should be a tree with containers as branches. | 01:23:27 |
| void | anyway, later. | 01:23:35 |
