Pharo Script of the Day: Unzip, the Smalltalk way

Hi everybody. Today a simple but useful script to uncompress a ZIP file in the current image directory. Notice the #ensure: send, Smalltalk provides an very elegant way to evaluate a termination block:

| zipArchive fileRef |
zipArchive := ZipArchive new.
fileRef := 'myFile.zip' asFileReference.
[ zipArchive
  readFrom: fileRef fullName;
  extractAllTo: FileSystem workingDirectory ]
ensure: [ zipArchive close ].
