启用将文件放入Ruby脚本 [英] Enable dropping a file onto a Ruby script

问题描述

我正在创建一个小的ruby脚本来调整图像大小并将它们保存在指定的目录中。我希望应用程序尽可能透明。

I'm creating a small ruby script to resize images and save them in a specified directory. I'd like the application to be as transparent as possible.

是否可以允许在所有平台中的文件丢弃到我的Ruby脚本？例如，用户将文件拖放到脚本上，然后将文件路径作为参数，并相应地调整图像大小 - 无GUI，无控制台等。

Is it possible to allow file dropping onto my Ruby script in all platforms? For instance, the user drags a file onto the script, which then takes the file path as an argument and resizes the image accordingly -- No GUI, no console, etc..

推荐答案

drop取决于操作系统（如果是Window Manager的Linux），所以没有。

The behavior of drag & drop is dependent on the OS (and in case of Linux of the Window Manager), so no.

在Windows中，您可以获得所需的行为。只需将一个.rb文件放在桌面上，拖动到这个文件上的文件将成为脚本的参数。

In Windows, you get the behavior you want for free. Just put a .rb file on the Desktop, and the files dragged onto it will be arguments to your script.

与Windows集成的另一个简单方法是写入注册表条目HKLM\Software\Classes * .jpg\myhandler\command与你想显示在Windows资源管理器的上下文菜单中的命令（右键点击一个jpg文件将弹出一个菜单，这将有你的脚本在菜单中）。

Another easy way for integrating with Windows is to write to registry entry HKLM\Software\Classes*.jpg\myhandler\command with the command you want to appear in the context menu of Windows Explorer (right click on a jpg file will popup a menu which will have your script in the menu).

我不使用拖放在Linux中掉下来，所以我不知道该怎么做。我希望它有更多的安全问题（权限必须正确，...），但您可以通过创建.desktop文件到达那里，请参阅 http://standards.freedesktop.org/desktop-entry-spec/latest/ ，或从〜/ Desktop / *中读取一些示例。桌面。

I don't use drag & drop at all in Linux, so I wouldn't know how to do that there. I would expect it to have more security issues (permissions must be right, ...) but you could get there by creating a .desktop file, see http://standards.freedesktop.org/desktop-entry-spec/latest/ for the complete standard, or read some examples from ~/Desktop/*.desktop .
