shift + enter/return Twice or More Doesn't Parse Correctly

[nigeljmckernan]

First off, this is a great package; I've been doing some playing around with this package and I'm surprised at how simple it is to use and set up. I thought it would involve much more complex networking stuff to actually make work.

This is not a major issue, more of an issue of readability for anyone who heavily relies on the %>% pipe operator from magrittr.

When running some standard pipeline-esque dplyr/magrittr code, it only parses the entire pipeline correctly if I only use shift + enter once, or not at all.

I'll demonstrate with a minimal reprex:

remoter> library(dplyr)

remoter> nycflights13::flights %>%
remoter+     filter(month == 1) %>%
remoter+     group_by(tailnum) %>%
remoter+     summarise(Max_Dep_Delay = max(dep_delay, na.rm = TRUE))
## A tibble: 3,149 x 2
#   tailnum Max_Dep_Delay
#   <chr>           <dbl>
# 1 N0EGMQ             54
# 2 N10156            126
# 3 N102UW             -7
# 4 N103US             -1
# 5 N104UW             29
# 6 N10575            184
# 7 N107US             -3
# 8 N108UW             -7
# 9 N109UW             -5
#10 N110UW            -10
## ... with 3,139 more rows 

However, when doing shift + enter more than once, remoter doesn't seem to like empty lines, even though this works perfectly fine in a regular R console:

remoter> nycflights13::flights %>%
remoter+     
remoter>     filter(month == 1) %>%
remoter+     
Error: object 'month' not found
remoter>     group_by(tailnum) %>%
remoter+     
Error: object 'tailnum' not found
remoter>     summarise(Max_Dep_Delay = max(dep_delay, na.rm = TRUE))
Error: object 'dep_delay' not found

I can get around that by inserting a # in the blank lines, though it's a bit annoying.

remoter> nycflights13::flights %>%
remoter+     #
remoter+     filter(month == 1) %>%
remoter+     #
remoter+     group_by(tailnum) %>%
remoter+     #
remoter+     summarise(Max_Dep_Delay = max(dep_delay, na.rm = TRUE))
# A tibble: 3,149 x 2
#   tailnum Max_Dep_Delay
#   <chr>           <dbl>
# 1 N0EGMQ             54
# 2 N10156            126
# 3 N102UW             -7
# 4 N103US             -1
# 5 N104UW             29
# 6 N10575            184
# 7 N107US             -3
# 8 N108UW             -7
# 9 N109UW             -5
#10 N110UW            -10
## ... with 3,139 more rows 

Is there a way for remoter to account for empty lines in some string of code just to make it a bit more readable in situations like these?

Regardless, thanks for the package; using the unbelievably laggy Remote Desktop to my work machine might finally have its end in sight!
