Hello,

Can anyone help me or give me any clue on how to rename a file (or
folder) inside a zip file without having to unzip it first. I'm trying
to do this using the rubyzip gem without luck.

Thanks,

ElĂ­as

You must require 'zip/zipfilesystem' and

Zip::ZipFile.open('my.zip') do |zipfile|
  zipfile.file.rename 'orignal_name.txt', 'new_name.txt'
end

And this is it, for more information see the Zip::ZipFileSystem class
documentation.

Regards.

Hi Franco,

Thanks for your reply, but still it ain't working for. I need to
rename a folder not a file. It works fine for file but not for
folders. I tried this and it correctly renamed the file build.yml to
builder.yml, BUT the folder wasn't rename, instead it created a new
folder in the same level of the one I wanted to rename. Any clues?

    Zip::ZipFile.open('/home/elioncho/Desktop/MyApp.zip'){|zf|
      parent_folder = zf.get_entry('Test/')
      file = zf.get_entry('Prueba/build.yml')
      parent_folder.name = 'Prueba/testing/'
      file.name = 'Prueba/builder.yml'
    }

I copied a wrong code, here it is. As I say before it only works for
renaming the file not the folder.

    Zip::ZipFile.open('/home/elioncho/Desktop/MyApp.zip'){|zf|
      parent_folder = zf.get_entry('Test/')
      file = zf.get_entry('Test/build.yml')
      parent_folder.name = 'Testing/'
      file.name = 'Test/builder.yml'
    }

There is no method to directly rename a directory, you must use the
rename in every file between the directory like this:

Zip::ZipFile.open('my.zip') do |zipfile|
  zipfile.file.rename 'original_dir/orignal_name.txt', 'new_dir/
original_name.txt'
end

And after that you can remove the original directory.
