Seems to work OK for me (Pharo 5 on Mac OS)

'/tmp/foo.txt' asFileReference writeStreamDo: [ :out | out << 'Pharo' ].

'/tmp/foo.txt' asFileReference exists.

'/tmp/foo.txt' asFileReference renameTo: 'bar.txt'.

'/tmp/foo.txt' asFileReference exists.

'/tmp/bar.txt' asFileReference exists.

'/tmp/bar.txt' asFileReference contents.

Maybe a permission problem ?

Hi,

Did you try `FileSystem root / 'a' / 'Path' / 'cat.jpg'` instead of
`FileSystem root / 'aPath/cat.jpg'`?

On what OS are you? I remember I had some trouble with the root on Windows.

Think of it as follows: Pharo is cross platform, forward slash is used on *nix and Mac OS, but not Windows where it is backslash. FileReference is an object oriented API that abstracts over that. Asking for an interpretation of the sub parts is a step too far (even if it would be handy).

We have an open bugtracker issue about this.

There is no conclusion right now how to handle this.

I understand that this path interpretation is a step too far , on the other hand we already do this in #resolveString:

see output of (on a windows platform(!))

(FileSystem root / 'aPath/file.txt') basename.
(FileSystem root / 'aPath\file.txt') basename.

vs.

(FileSystem root resolveString:'aPath/file.txt') basename.
(FileSystem root resolveString:'aPath\file.txt') basename.

#/ could behave like #resolveString

And for example:

(FileLocator vmDirectory / 'testdir/file.txt') writeStream << 'Test'

will succeed, if the directory <vmdirectory>/testdir/ exists (it does not try to create a file called "testdir/file.txt", but really just "file.txt").

(see issue 13217)
