 hexa | is there a way to set an optional option default? | 23:21:25 |
| hexa | default = if foo then "bar" else omit;
| 23:21:46 |
| hexa | * default = if foo then "bar" else omit; # if not foo, consider the value unset
| 23:22:21 |
| hexa | uhhhhhh | 23:25:58 |
| hexa | can I like | 23:26:00 |
| hexa | bla = mkOption {
} // lib.optionalAttrs (cond) {
default = "bar";
};
| 23:26:37 |
| hexa | probably can | 23:26:51 |
 Migrated to @infinidoge:inx.moe | I think that would work | 23:27:14 |
| Migrated to @infinidoge:inx.moe | Might need parenthesis, but even then | 23:27:23 |
| hexa | 🙂 | 23:27:35 |
| Migrated to @infinidoge:inx.moe | If it doesn't work, you can definitely do it through config though | 23:28:44 |
| Migrated to @infinidoge:inx.moe | config.bla = lib.mkIf cond (lib.mkDefault "value");
| 23:29:08 |
| hexa | yeah, but that's not really discoverable | 23:29:36 |
| hexa | * bla = mkOption {
defaultText = ''
Something if cond, else unset
'';
} // lib.optionalAttrs (cond) {
default = "bar";
};
| 23:30:03 |
| hexa | update the example with defaultText | 23:30:12 |
| Migrated to @infinidoge:inx.moe | You're already gonna need to use the documentation text override, so I don't think it would really affect the discoverability that much | 23:30:19 |
| hexa | that was always going to be the case | 23:30:32 |
| hexa | but defaultText makes the condition discoverable | 23:30:39 |
| hexa | as opposed to hiding it in the implementation | 23:30:47 |
| Migrated to @infinidoge:inx.moe | My example was just how the default part could be done, wasn't a self-contained example | 23:31:58 |
| hexa | I understood config as the implementation section of the module | 23:32:55 |
| Migrated to @infinidoge:inx.moe | It's... weird, unfortunately. Options are mostly the interface, but with defaults they are somewhat load bearing | 23:34:02 |
| Migrated to @infinidoge:inx.moe | All default does is assign a value with a priority, the end result here is the same | 23:34:15 |
