Luke Boswell (Oct 18 2022 at 09:33): Luke Boswell (Oct 18 2022 at 09:33):I find I am regularly running roc test and then roc dev... given the distinction between check, run, dev would it be a good idea to have roc dev also run roc test? I would also ask for roc format to be included, but it's not quite at the same level of maturity. OTOH that might be beneficial for finding issues bugs?
I am continuously using expectations to check my logic as I go along. Though, I have been starting to use roc repl more for testing smaller bits of code, however it doesn't support expect calls yet.
I'm also interested to know what workflow people are using? I assume it's difficult to just write, compile and it just works. I'm looking forward to experimenting with these ideas in the editor.
Anton (Oct 18 2022 at 09:41):would it be a good idea to have roc dev also run roc test?
I'd say we definitely want the ability to run roc dev without roc test.
Luke Boswell (Oct 18 2022 at 10:47):Why is that? I assume it significantly slows down the compile loop, but I also imagine you could use roc run if you just wanted it to run fast. What about something like roc dev --test or roc dev --no-test?
Anton (Oct 18 2022 at 11:31):@Luke Boswell I moved the previous messages to their own topic.
For context: dev compiles fast so you can iterate quickly for development. run compiles slower to create the fastest possible binary.
Since dev is all about a fast feedback loop I don't think we should add things that make it slower :p
What about something like roc dev --test or roc dev --no-test?
I would expect people to use roc test && roc dev. Providing redundant ways to do the same thing does not seem necessary to me, but I welcome people to convince me otherwise :)
Brian Carroll (Oct 18 2022 at 11:36):Yeah exactly, it's a core design goal to have some command that just does the fastest possible compilation and that's it. And tests take time to run. You often want tests too, but not absolutely always so we shouldn't force that.
Brendan Hansknecht (Oct 18 2022 at 14:01):I think tests fit much better with some sort of watch command to auto run on update of files. Definitely requires limited scope/caching as projects get bigger.
