The answer will depend on which version of Pharo you are using, but for Pharo7:

  '/Users/black/graceProgs/lists/../../Development/mg/gracelang/albums_junk.grace'
asFileReference canonicalize
  "File @ /Users/black/Development/mg/gracelang/albums_junk.grace"


The reason the '..' segments are left in is because while the result
is probably what you are looking for, if the original reference
contains symbolic links you may end up with a different result to what
the file system will return.

On Pharo 6 use "asAbsolute" on a FileReference, like this:

'/Users/black/graceProgs/lists/../../Development/mg/gracelang/albums_junk.grace'
asFileReference asAbsolute

"File @ /Users/black/Development/mg/gracelang/albums_junk.grace"


Cheers, Andreas
