| bglgwyng | I need a way to specify build targets in Setup.hs's configure phase to fix it | 14:47:05 |
| bglgwyng | But it doesn't support unfortunately | 14:47:56 |
 teo (they/he) | Haskell.nix seems to pass the name of the component to configure https://github.com/input-output-hk/haskell.nix/blob/751e1561c3fbc0a5cf136a689b70bbce567852a8/builder/comp-builder.nix#L239 | 15:20:27 |
 yliceee | I'm getting
Error while expanding response file: /tmp/nix-shell.iCOh0S/ghci519500-0.rsp: openFile: does not exist (No such file or directory)
in the LSP mode stderr at random times in a haskell project using cabal/nix/direnv/emacs (with LSP mode and envrc mode) | 21:22:43 |
| yliceee | im unable to consistently replicate. has anyone else seen this? | 21:23:22 |

 alexfmpe | I've seen that a few times | 22:54:40 |
| alexfmpe | I ended up disabling direnv as it's been too unreliable for me | 22:56:12 |
| alexfmpe | Also kept getting into stale states forcing me to rm .direnv after a lot of "how is this possible" | 22:57:08 |

 sterni | bglgwyng: as far as I know, there is no way to specify the build targets at configure time | 10:28:22 |
| sterni | The package database is prepared by us and includes all dependencies Cabal reports to us when generating the expression. Not sure if you could influence this to trim down to specific targets, in any case cabal2nix does not support this at the moment. | 10:29:38 |
| sterni | interesting that doesn't seem to be documented? | 10:31:01 |
| sterni | it would be nice if we could set testTargets and buildTargets at configure time already | 10:31:28 |
| bglgwyng | Indeed I tried the same thing but it didn't work | 11:46:44 |
| bglgwyng | Maybe haskell.nix uses its own patched version? | 11:47:06 |
| bglgwyng | No, it doesn't. | 13:20:35 |
