Mo (Dec 11 2024 at 22:04): Mo (Dec 11 2024 at 22:04):Hi again, I see some issues and conversations about dbg, but I'm just trying a simple roc dev or roc dev main.roc with the following, and get no output:
app [main] { pf: platform "https://github.com/roc-lang/basic-cli/releases/download/0.17.0/lZFLstMUCUvd5bjnnpYromZJXkQUrdhbva4xdBInicE.tar.br" }
main =
dbg "hello"
Task.ok {}
If dbg is currently not working, what's a good way to do print debugging? From my extremely novice understanding, it seems functions would have to be converted to Tasks to enable Stdout, right?
Brendan Hansknecht (Dec 11 2024 at 22:08):Hmmm... I think I may have broken this with a pr the other day
Brendan Hansknecht (Dec 11 2024 at 22:13):If you can go back to this commit or earlier, it should work: 50ec8ef1d1aa9abb2fda6948fb13abb431940ddf
Brendan Hansknecht (Dec 11 2024 at 22:13):https://github.com/roc-lang/roc/commit/50ec8ef1d1aa9abb2fda6948fb13abb431940ddf
Mo (Dec 11 2024 at 22:18):Nice, I'm using Nix (also novice-level) so in theory this should be straightforward, right? I'll give it a go
Mo (Dec 11 2024 at 22:52):Excellent, dbg works again, thank you! For reference, I changed this line in my flake.nix:
roc.url = "github:roc-lang/roc?ref=50ec8ef1d1aa9abb2fda6948fb13abb431940ddf";
Mo has marked this topic as resolved.
Brendan Hansknecht (Dec 11 2024 at 23:12):I'll have a proper fix up soon
Brendan Hansknecht (Dec 11 2024 at 23:12):Trying to do a larger cleanup of some of our handling here.
Brendan Hansknecht (Dec 12 2024 at 00:25):Properly fixed on main starting at https://github.com/roc-lang/roc/commit/146710a129ec4f5403522dba2b334a19521d885d
Mo (Dec 12 2024 at 00:29):That was fast! Latest commit works for me :)
Luke Boswell (Dec 12 2024 at 00:31):Roc: the Fast, Friendly, Functional language ... and dev team :joy:
