Porting code to Pharo 2.0

Pharo 2.0 changed some basic API bits, and I cannot found the new way of doing the following:

  1. FileDirectory default directoryNamed: aFolderString.
  2. FileDirectory on: aFilename.
  3. FileDirectory default assureExistenceOfPath: aString.
  4. ReferenceStream on: stream.

What would be the new equivalent code? Is there an update guide available describing how to translate or port code?

ReferenceStream is not supported anymore and has been deleted in Pharo 2.0. You should use Fuel which is well written, well documented, well tested and very fast. http://rmod.lille.inria.fr/web/pier/software/Fuel

The following statements correspond do the ones you put in your question.

  1. FileSystem workingDirectory / aFolderString
  2. aFilename asFileReference
  3. aString asFileReference ensureDirectory
  4. ReferenceStream does no longer exist in 2.0.

aPathString asFileReference resolves aPathString, so if there are slashes in your name you will end up in a subdirectory.

/ on the other hand takes a single directory or file name as an argument, and does not resolve further subdirectories. Depending on your platform you can easily refer to a file named foo/bar with a slash in the name with FileSystem workingDirectory / 'foo/bar'.
