Is it possible to break 1 line of code into multiple in atom IDE, just like in Rstudio

Question

I am new to using Julia and the atom IDE, and I was wondering if it was possible to somehow just press enter and have the computer run 1 line of code spread over multiple lines, and still have it recognize that it is still the same 1 line of code, just like in Rstudio? (I want this for readability purposes only)

what I mean is something like:

println("Hello 
world")

and be able to highlight and run this script without receiving an error message.

Yes. The method differs based on what the line of code contains, or specifically, where you want to break the line.

For a string like you've posted in the question, you have to precede the newline with a \ character, to inform Julia that you're using this newline only for readability, and don't want it to be included in the actual string. (Note: I'll be illustrating these with the command-line REPL that has the julia> prompt, but the same principles apply in the Atom/VS Code based IDE setups too).

julia> println("Hello \
       world")
Hello world

Outside of strings, if the current line isn't complete, Julia automatically looks for the continuation in the next line. This means that to break a line into multiple ones, you have to leave all but the final line incomplete:

julia> 1 + 
       2 + 
       3 * 
       4
15

julia> DEPOT_PATH |>
       first |> 
       readdir
16-element Vector{String}:
 "artifacts"
 "bin"
  ⋮

julia> 1,
       2,
       3
(1, 2, 3)

In some cases when you don't have a convenient binary operator to leave hanging like the above, you may have to start your line with an opening parenthesis, so that Julia will know that it's a continuous statement until the closing parenthesis is encountered.
