Hi Stef,
once upon in time :-) I picked up the notion that #printString "should"
return a string which (when executed) results in the printed object.
Whereras #displayString is "nicer" for the user. Not quite sure if this
still applies though. But in this regard what about something like
fr1 := FileSystem disk root / 'folder' / 'file.txt'.
fr2 := FileSystem memory root / 'folder' / 'file.txt'.
fr1 printString. "FileSystem // 'file:///folder/file.txt'"
fr2 printString. "FileSystem // 'memory:///folder/file.txt'"
fr1 displayString. "'file:///folder/file.txt'"
fr2 displayString. "'memory:///folder/file.txt'"
For FileReferences which use a FileSystem with a configured Store those
settings could be added to the URL as host/query. E.g. for a WebDav
FileReference:
#printString
"FileSystem // 'webdav://uid:pwd@host/folder/file.txt&usePatch=false'"
#displayString
"'webdav://uid:pwd@host/folder/file.txt'"
CU,
Udo

Hi Udo
Thanks for the suggestion. It means that the printOn: should really
involve the FieSystem and this is probably right.
Now the point of the printOn: vs the displayString is that we can get
back an object and right now we get a string :)
Your URI suggestion should be applied to the displayString or the
asFileReference should understand it.
I added your feedback to the entry.

I'm a bit biased on this. IMHO this simplification in the #printString
(which I quite like BTW!) is only applicable to Files in DiskFileSystem.
If you have a FileReference on a non disk filesystem (e.g.
fr1 := FileSystem memory root / 'folder' / 'test.txt'.
"memory:///folder/test.txt"
on use this simplified #printString you'll end up with
'/folder/test.txt' asFileReference.
This might be confusing as this does not mention the filesystem. So
you might end up creating a new instance via
fr2 := '/folder/test.txt' asFileReference.
which is not equal to the original fileRef:
fr1 = fr2 "false"
As I do like the #printString simplification ... why not simply adopt
a URI style scheme for FileReferences. This would allow encoding the
filesystem type (e.g. file://, memory://, zip://, s3://) including
parameters like host if needed and of course the path.

Subject: [Pharo-dev] About file printOn: method
Hi
I will implement the following because this is too annoying.
currently
'tmp/foo.txt' asFileReference
>
File @ tmp/foo.txt
and it would be much much better to get back
'tmp/foo.txt' asFileReference
So that we can get
{ 'tmp/foo.txt' asFileReference }
> { 'tmp/foo.txt' asFileReference }
and not
"an Array(File @ tmp/foo.txt)"
In addition we should turn the current printOn: method into a
displayString method so that
a list of fileReference can be well display with File @ tmp/foo.txt

example
