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").

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). > On 18 Apr 2016, at 10:56, Valentin Ryckewaert <valentin.ryckewaert(a)gmail.com> wrote: > > I'm on Linux > > Is it wanted that root / 'a' / 'foo.txt' is different than root / '.foo.txt' ?

Re: [Pharo-users] final version of pharo syntax cheat page

Under Methods, you might want to change it to this: Methods are public and virtual. They are always looked up in the class of the receiver. By default a method returns self. Class methods follow the same dynamic lookup as instance methods. Method factorial defined in class Integer.

I'm on Linux Is it wanted that root / 'a' / 'foo.txt' is different than root / '.foo.txt' ?

Re: [Pharo-users] Rename a file

by Michal Balda

Hi, I think the problem is using 'aPath/cat.jpg' as a single string (= as a single component of the path). This: path1 := FileSystem root / 'a/b/c.txt'. is different to: path2 := FileSystem root / 'a' / 'b' / 'c.txt'. Compare the results when I ask for the parent directory: path1 parent "-> File @ /" path2 parent "-> File @ /a/b" When renaming, the #renameTo: method takes the #parent directory as the base for the target filename. Therefore: (FileSystem root / 'a/b/c.txt') renameTo: 'my.txt'. will try to create file: FileSystem root / 'my.txt' Whereas: (FileSystem root / 'a' / 'b' / 'c.txt') renameTo: 'my.txt'. will try to create file: FileSystem root / 'a' / 'b' / 'my.txt' And in your case, FileSystem root is probably not writable.

Using your method (A string asFileReference) it works thanks ! But if you use FileSystem root / .... I get the "same" object but it's still not working.
