从zip存档加载ruby源？ [英] Loading ruby source from a zip archive?

问题描述

我有一个mod_rails服务器，磁盘空间，奇怪的是，是一个溢价。有没有办法压缩我的应用程序的来源，如 Python的zipimport ？

I have a mod_rails server where disk space, oddly enough, is at a premium. Is there a way for me to compress my application's source, like Python's zipimport?

这有明显的缺点，所以我应该可以分解并在磁盘空间使用镍，但我认为这是值得一试。

There are obvious disadvantages to this, so I should probably just break down and spend a nickel on disk space, but I figured it'd be worth a shot.

推荐答案

哦，这很整洁。查看 ruby​​zip 宝石：

Oh, this is neat. Check out the rubyzip gem:

ruby​​zip还提供了
zip / ziprequire.rb 模块（源），允许
ruby​​从zip
档案载入ruby模组。

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

（更新 ziprequire.rb不再存在于rubyzip gem中，但来源链接似乎包含其旧内容。）

(Update: The ziprequire.rb is no longer present in the rubyzip gem, but the source link appears to contain its old content nonetheless.)

这样。这只是稍微修改从他们的例子：

Like so. This is just slightly modified from their example:

require 'rubygems'
require 'zip/zipfilesystem'
require 'zip/ziprequire'

Zip::ZipFile.open("/tmp/mylib.zip", true) do |zip|
  zip.file.open('mylib/somefile.rb', 'w') do |file|
    file.puts "def foo"
    file.puts "  puts 'foo was here'"
    file.puts "end"
  end
end

$:.unshift '/tmp/mylib.zip'
require 'mylib/somefile'

foo    # => foo was here

您不必使用rubyzip库来创建压缩库。您可以使用CLI zip。

You don't have to use the rubyzip library to create the zipped library, of course. You can use CLI zip for that.
