[Pharo-dev] Path * '' vs. Path workingDirectory

[Alistair Grant]

Hi All,

Is there any practical difference between (Path * '') and (Path
workingDirectory)?

Their internal representation is different:

- (Path * '') has one empty segment
- Path workingDirectory has no segments

But as far as I can tell they are otherwise the same:


| fs frEmpty frWD |

fs := FileSystem disk.
frEmpty := FileReference fileSystem: fs path: (Path * '').
frWD := FileReference fileSystem: fs path: Path workingDirectory.
String streamContents: [ :stream |
stream
        << 'frEmpty: '; 
        << frEmpty printString; cr;
        << 'frWD: '; 
        << frWD printString; cr;
        << '= : ';
        << (frEmpty absolutePath = frWD absolutePath) printString; cr.
]

'frEmpty: "File @ "
frWD: "File @ ."
= : true
'


Cheers,
Alistair
