I use it a lot to uncompress external resources like this:

fileRef := ....
GZipReadStream unzip: fileRef basename to: FileSystem workingDirectory.

but it could be used to pass a directory as String I guess.

Comment should be corrected.

2016-04-19 9:54 GMT-03:00 stepharo <stepharo@free.fr>:

unzip: fullFileName to: pathString
�� �� "Unzip the contents of the file specified by the full path name fullFileName to the location given by pathString."

so we would expect to pass a string in the second argument?

the unique sender of it in the system

unzip: fullFileName
�� �� "Unzip the contents of a gzipped file specified by its full file name to the current working directory"

�� �� ^ self unzip: fullFileName to: FileSystem disk workingDirectory


but the implementation seems to indicate that fullFileName is should be a string as well as pathString

unzip: fullFileName to: pathString
�� �� "Unzip the contents of the file specified by the full path name fullFileName to the location given by pathString."

�� �� | zipped buffer unzipped newName |
�� �� newName := fullFileName copyUpToLast: FileSystem disk extensionDelimiter.
�� �� pathString asFileReference ensureCreateDirectory.
�� �� unzipped := FileStream newFileNamed: (pathString asFileReference / newName) fullName.
�� �� unzipped ifNil: [self error: pathString, ' looks incorrect'].
�� �� [ unzipped binary.
�� �� zipped := self on: (FileStream readOnlyFileNamed: fullFileName).
�� �� buffer := ByteArray new: 50000.
�� �� [zipped atEnd] whileFalse: [unzipped nextPutAll: (zipped nextInto: buffer)]]
�� �� �� �� ensure: [
�� �� �� �� �� �� zipped close.
�� �� �� �� �� �� unzipped close].
�� �� ^ newName

Am I correct to think that the comments are not really good enough?
