Module: Zip::ZipFileSystem

Included in:
ZipFile
Defined in:
lib/amp/dependencies/zip/zipfilesystem.rb

Overview

The ZipFileSystem API provides an API for accessing entries in a zip archive that is similar to ruby’s builtin File and Dir classes.

Requiring ‘zip/zipfilesystem’ includes this module in ZipFile making the methods in this module available on ZipFile objects.

Using this API the following example creates a new zip file my.zip containing a normal entry with the name first.txt, a directory entry named mydir and finally another normal entry named second.txt

require 'zip/zipfilesystem'

Zip::ZipFile.open("my.zip", Zip::ZipFile::CREATE) {
  |zipfile|
  zipfile.file.open("first.txt", "w") { |f| f.puts "Hello world" }
  zipfile.dir.mkdir("mydir")
  zipfile.file.open("mydir/second.txt", "w") { |f| f.puts "Hello again" }
}

Reading is as easy as writing, as the following example shows. The example writes the contents of first.txt from zip archive my.zip to standard out.

require 'zip/zipfilesystem'

Zip::ZipFile.open("my.zip") {
  |zipfile|
  puts zipfile.file.read("first.txt")
}
