Luke Boswell (Nov 19 2022 at 19:34):I like it! I'm certain I will use this a lot.
The only additions I could think of, and this is probably a terrible idea, but I thought I'd mention in the spirit of brainstorming...
What if dbg took arguments using - or --? So something like dbg myExpr --singleLine --recursive. I'm not sure which arguments you might want but mayne you could have; text descriptions, single vs multiline printing, pretty or short printed, expand structures recursively or not, print stack, print heap, dislpay call graph, pause program at this point and give me a REPL to play with variables or step through line by line, or maybe other debuging related things?
Georges Boris (Nov 19 2022 at 20:19):You probably saw this already but elixir's recent implementation of dbg was pretty exciting because of all it's live debugging/livebook integrations. It would be great if we left the proper doors open for possibly experimenting with things like that on our editor:

Richard Feldman (Nov 19 2022 at 21:01):whoa, I hadn't seen that
Richard Feldman (Nov 19 2022 at 21:01):but it looks awesome! :heart_eyes:
Richard Feldman (Nov 19 2022 at 21:03):yeah I definitely think the editor should be free to do more with this than the command line would :big_smile:
Richard Feldman (Nov 19 2022 at 21:03):and I also think that pipeline behavior is cool, and worth revisiting in the context of expanding dbg to work as an expression
