什么是与Firefox插件进行通信的最佳方式 [英] What's the best way to communicate with a Firefox addon

问题描述

我需要能够从Firefox中的活动选项卡获取URL。 DDE不适用于多个实例，所以我想我可以建立一个插件来设置一个全局原子或其他东西。

我也想过也许我可以使用剪贴板，但我不想覆盖任何现有的文本，自定义剪贴板类型似乎不被支持。 / p>

我不想诉诸写一个文件来做简单的IPC ...所以在我做之前...有没有更好的选择，如此简单。

谢谢 解决方案

最好的方法，但我认为使用 MozRepl 将帮助你。
MozRepl将使您能够通过telnet与firefox进行交互。

 ％telnet localhost 4242 
 Trying 127.0 .0.1 ... 
连接到本地主机。 
转义字符是'^]'。 
 
欢迎来到MozRepl。 
 
 repl> content.location.href 

 repl> 
  

安装MozRepl后，您可以使用这个小小的ruby脚本获取当前操作选项卡的url。 / p>

  require'net / telnet'
 $ b $ = Net :: Telnet.new（'Port'=> ; 4242）
 t.waitfor（/ repl。*> /）
 puts eval（t.cmd（content.location.href）.split [0]）
 t。关闭
  

I need to be able to get the URL from the active tab in Firefox. DDE doesn't work with multiple instances so I was thinking that I could build an addon that sets a global atom or something.

I also thought that maybe I could use the clipboard, but I don't want to overwrite any existing text and custom clipboard types doesn't seem to be supported.

I don't want to resort to writing a file just to do simple IPC...so before I do it...is there a better choice for something so simple.

thanks

解决方案

I don't know if its the best way, but I think using MozRepl will help you. MozRepl will make you able to interact with firefox through telnet.

% telnet localhost 4242
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.

Welcome to MozRepl.

repl> content.location.href
"http://stackoverflow.com/questions/8525428/whats-the-best-way-to-communicate-with-a-firefox-addon"
repl> 

After installing MozRepl, You can use this little ruby script to get the url of currently opend tab.

require 'net/telnet'

t = Net::Telnet.new('Port' => 4242)
t.waitfor(/repl.*>/)
puts eval(t.cmd("content.location.href").split[0])
t.close
