Working with zipped files

Hi,

by peeking around in "Deep into Pharo" I thought that

| zf fr |
fr := 'I:\SAS_Projekte\project.egp' asFileReference.
zf := FileSystem zip: fr.
zf store open.

should be used to open a zip file programmatically. That fails with
"ZnInvalidUTF8: Invalid utf8 input detected"

Looking at MCMczReader, it skips the FileSystem API completely.

In FileSystem-Tests-* I find DiskFileSystemTest and
MemoryFileSystemTest, no ZipFileSystemTest to see how it's supposed to
be done.

Did I do it wrong? Or is FileSystem not yet "finalized" in that area?

Best regards,
Markus

Re: Working with zipped files

Do you want to work with ZIP files, or specifically with MCZ ?

Just a zip file with a member called project.xml which I want to
extract, change and rezip...

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

General idea was to use ZipArchive instead of MCZ-related code.

If above code fail to work for you, why not publish the file we are talking about? The it will be possible to test the code you are asking for.

Sorry, I wasn't clear. MCZ was just my example. The real question was,
if the ZipFileSystem API can be used or not... I will go with ZipArchive
and friends then.
