Chloe Bai (Oct 03 2024 at 14:57): Chloe Bai (Oct 03 2024 at 14:57):hi!! would someone be able to provide some code examples of arithmetic operations with correct roc file formatting. i'm really struggling to find the documentation for format and correct syntax.
Chloe Bai (Oct 03 2024 at 14:59):right now i have this:
Num.sub 5000 30000
but i think the file needs a header and i'm not sure how to set that up? when i do
cargo run -- crates/cli/tests/subtraction_test.roc
it gives me this error:
thread 'main' panicked at crates/reporting/src/error/parse.rs:3937:14:

Chloe Bai (Oct 03 2024 at 15:10):thank you!
Chloe Bai (Oct 03 2024 at 15:33):@Brendan Hansknecht do you know how i format the header of a file?
Brendan Hansknecht (Oct 03 2024 at 15:46):Yeah, I would just take the header from one of the neighboring files or examples. For example, if you want a simple CLI app for testing, I would just base it of the hello world example
