Re: [ESS] readline with trailing space

[Greg Minshall via ESS-help]

Jeremie,

i am runnnig

ess-version: 18.10.3snapshot [elpa: 20210109.1455] (loaded from
/home/minshall/.emacs.d/elpa/ess-20210109.1455/)

under arch linux.  i don't see the behavior you see.  in my
configuration, both test() and test1() seem to accept a line of
characters.

have you tried starting emacs -whatever (like, -q or -Q or ...)?

cheers, Greg

[ESS] readline with trailing space

[Jeremie Juste via ESS-help]

Hello,

I have noticed a behavior that I don't understand. When I call the
following function from the prompt.
test <- function(){
a <- readline("selection: ")
a
}

> test()
> selection: |
I can only type one character and the readline function exits before I can
press enter.

however

test1 <- function(){
a <- readline("selection:")
a
}
> test1()
> selection:|
works as expected.
> selection: abc[Ret]

However calling directly readline with a space in the prompt does what I
would expect.

> a <- readline("selection: ")
> selection: abc[Ret]
> a
> "abc"

It is the expected behavior or am I missing something?


I can reproduce this behavior on Windows and Linux.
I cannot reproduce this behavior in a bash terminal, or on RStudio.
I'm using ess-version: 18.10.3snapshot [elpa: 20200825.829] (loaded from
/home/djj/.emacs.d/elpa/ess-20200825.829/) but the problem still persist
in the latest version. 

Best regards.
