ruby - gem ocra 生成巨大的文件

Question

我创建了一个简单的 ruby​​ 脚本

require 'gtk3'

def destroy( widget )
   Gtk.main_quit
end

Gtk.init
window = Gtk::Window.new :toplevel
window.set_title( "helloworld.rb" )
window.set_border_width( 10 )

window.signal_connect( "delete_event" ) {
   destroy(nil)
}

button = Gtk::Button.new :label => "Button"
window.add( button )
button.show
window.show
Gtk.main

此脚本创建一个带有按钮的非常简单的 GUI。如果我使用 ocra gem使用命令创建 script.exe

ocra script.rbw

生成一个 70 MB 的文件，对于带有按钮的简单窗口来说太大了。我究竟做错了什么？我能做些什么来消除这个障碍？Ocra输出是这样的(用命令“ocra script.rb”输出而不是“ocra script.rbw”，但过程是一样的)

我用 cli script.rb 尝试相同的过程

puts "Hello World"

结果:2,6 Mb 仅用于打印 Hello World。我能做什么？

Answer 1

Ocra 不是编译器，它是一种准备运行的 ruby​​。它需要 ruby​​、所有加载的 gem 和脚本并将它们打包在一起。

当您调用 exe 时，它​​会提取所有内容并使用包含的 ruby​​ 调用 ruby​​ 脚本。脚本执行后，它会删除所有内容。如果您的脚本失败，则删除没有完成，您会在临时目录中找到很多文件。

在您使用 require 'gtk3' 的情况下，gtk3 支持的所有内容都已加载。看起来很多。

Hello World 的 2.6MB 不仅包含屏幕输出，还包含 ruby​​ 能够执行的所有操作 - 即使它没有执行，

你能做什么？尝试找到不需要那么多的版本。
