a ruby library for reading and writing zip files

rubyzip is a ruby library for reading and writing zip files.

Requirements - Ruby 1.9.2 or greater

There is more than one way to access or create a zip archive with rubyzip. The basic is modeled after the classes in java.util.zip from the Java SDK. This means there are classes such as Zip::ZipInputStream, Zip::ZipOutputStream and Zip::ZipFile. Zip::ZipInputStream provides a basic interface for iterating through the entries in a zip archive and reading from the entries in the same way as from a regular File or IO object. ZipOutputStream is the corresponding basic output facility. Zip::ZipFile provides a mean for accessing the archives central directory and provides means for accessing any entry without having to iterate through the archive. Unlike Java‘s java.util.zip.ZipFile rubyzip‘s Zip::ZipFile is mutable, which means it can be used to change zip files as well.

Another way to access a zip archive with rubyzip is to use rubyzip‘s Zip::ZipFileSystem API. Using this API files can be read from and written to the archive in much the same manner as ruby‘s built-in classes allows files to be read from and written to the file system.

rubyzip also features the zip/ziprequire.rb module which allows ruby to load ruby modules from zip archives.
