When using in REPL, `JuliaSyntax.jl` does not seem to work well with multiline parsing?

When I want to type

map(1:10) do x
    2x
end

after I type map(1:10) do x and hit return, I got

julia> map(1:10) do
ERROR: ParseError:
Error: premature end of input
@ REPL[11]:2:1
map(1:10) do
Error: premature end of input
@ REPL[11]:2:1
map(1:10) do
Error: Expected `end` but got unexpected tokens
@ REPL[11]:2:1
map(1:10) do

Or if I want to type

 w = u +
     v +
     1

I got

julia> w = u +
ERROR: ParseError:
Error: premature end of input
@ REPL[14]:2:1
w = u +

But I can do them with copy-paste:

Can we make the REPL-mode tolerate multiline code a little bit more?

Yes this is a bug, thanks for opening an issue!

What we need to do is detect "incomplete" expressions and emit Expr(:incomplete) for these to make this work.

In the meantime, you can use the REPL's ALT+Return keybinding to enter a newline without going through the parser (this is what keeps me sane 😅 )

Hi @c42f, I just tried Alt+Return (on macOS is it probably Option+Return?) But it does not seem to work. Is it a different keybinding on Macs? I have tried Control+Return & Command+Return though.

I'm not sure I don't use macOS. It might be a setting on your terminal emulator https://apple.stackexchange.com/questions/1391/equivalent-to-alt-in-terminal ?

Oh, it works. Maybe because I was using iTerm? I don't know. Thanks for helping!
