Well, even it's not the central point of the discussion let make this

Hi John,
First, the unix and linux filesystem allows the use of any nonzero character in

I apologize. I did not mean to flame, merely to point out a typical usage
of tilde that might have escaped the discussion.
As you say, Kurt's fix makes this all moot.
I also apologize for wasting everyone's time with my spam.

At the risk of looking silly, note that all of this is now largely moot
anyway (or will be with the next release of R), thanks to Kurt Hornik's
fixing of the bug in question (which he announced on this thread prior to
but I read after Paul's).

Hi Gabriel,
I actually want to make renames over thousands of files. But if I am not able
to express the source filename of the rename operation I will not be able to
get the work done. Besides the fact that there are issues I think that R is

Hi Gabriel,
It may be bad practice, but you don't always have control over the file
name.
E.g. if someone shares a file with a tilde in it -- yes it is simple to
rename but it is extra time, and you might not bother to rename a file
without foreknowledge of this bug in the first place.

Hi Frank,
I'm hesitant to be "that guy", but in case no one else has brought this up
to you, having files with a tilde in their names (generally but especially
on a linux system, where ~ in file names has a very important special
meaning in some cases, as we know) strikes me as an exceptionally ba
Hi,
yes, I have seen this package and it has the same tilde expanding problem.
Please excuse me I will cc this answer to r-help and r-devel to keep the
discussion running.
Kind regards,

Hi,
to get rid of any possible filename modification I started a little project to
cover my usecase:

This is my first R package, suggestions and a review are welcome.
Thanks in advance

Expand a path name, for example by replacing a leading tilde by

Hello,
R 3.6.0 on Ubuntu 19.04.
Since no one mentioned it, notice that the tilde in the middle of a
string needs to be surrounded by spaces to be expanded.
The first code line works as expected, only the second is wrong (buggy).
path.expand('a~b')
#[1] "a~b"
path.expand('a ~ b')

I think that that IS what libreadline is doing if one allows a whitespace
separated list of file names.
As reported in R-help,
How can expanding tildes anywhere but the beginning of a file name NOT be
considered a bug?

It looks like a bug in R, but not necessarily a bug in libreadline: we
may just be using tilde_expand improperly.

It doesn't seem to be possible if readline is enabled and works
correctly.
Calls to path.expand [1] end up [2] in R_ExpandFileName [3],
