Seth Workman (Mar 07 2023 at 04:21): Seth Workman (Mar 07 2023 at 04:21):I started going through some of the tutorial using "roc repl" and I'm curious if the repl is planning on having automatic indentation when creating functions. Example below
» test = \a -> (press enter after the ->)
… a (press enter - doesn't auto indent) -- compiler sad (error)
» test = \a -> (press enter after the ->)
… a (press space, press enter) -- compiler happy
Ayaz Hafiz (Mar 07 2023 at 04:55):That is a great question and I think it would be a great idea to support. My suspicion is that it wouldn't even be too hard to implement with the current design of the roc parser+repl.
Seth Workman (Mar 07 2023 at 21:23):I created an issue for this here https://github.com/roc-lang/roc/issues/5101
Luke Boswell (Mar 08 2023 at 09:08):For anyone interested I think the relevant JS is in www/build/repl/repl.js
Brendan Hansknecht (Mar 08 2023 at 15:29):That is probably just the web repl. Should be different rust code for the cli repl as well
Brian Carroll (Mar 09 2023 at 17:35):The repl.js file prints out each string from Rust exactly as it is, preformatted, into a HTML pre tag. All of the formatting and indentation code is in Rust.
Brian Carroll (Mar 09 2023 at 17:36):This is to share as much as possible and keep things consistent
Seth Workman (Mar 15 2023 at 14:35):I was looking into the possibility of auto indent but it seems RustyLine doesn't support it. https://github.com/kkawakam/rustyline/issues/453

Seth Workman (Mar 15 2023 at 17:40):Any ideas?
