Even adding a letter at the front it still doesn't like the underscore. Is it impossible to use a filename like this with Roc?
Luke Boswell (Dec 01 2022 at 06:01):I'm not aware of any restrictions, I had a look through the tutorial and guide for elm programmers too. I'm guessing it may something related to the naming convention for defs. I notice in the tutorial that for defs
You can name a def using any combination of letters and numbers, but they have to start with a letter.
Richard Feldman (Dec 01 2022 at 06:22):ah! Modules you can import need to start with a capital letter. This is so that the compiler can tell the difference between Foo.bar (look for bar to be exposed from a module named Foo) and foo.bar (look for a record field bar on a variable named foo)
I'll make a note to add that to the tutorial!
