## Installing
### Recommended
```
gem install proxifier
```
### Edge
```
git clone https://github.com/samuelkadolph/ruby-proxifier
cd ruby-proxifier && rake install
```
## Rationale
This gem was created for 2 purposes.
First is to enable ruby programmers to use HTTP or SOCKS proxies
interchangeably when using TCPSockets. Either manually with
`Proxifier::Proxy#open` or by `require "proxifier/env"`.
The second purpose is to use ruby code that doesn't user proxies for users that
have to use proxies.<br>The pruby and pirb executables are simple wrappers for
their respective ruby executables that support proxies from environment
variables.
## Usage
### Executable Wrappers & Environment Variables
proxifier provides two executables: `pruby` and `pirb`. They are simple
wrappers for your current `ruby` and `irb` executables that requires the
`"proxifier/env"` script which installs hooks into `TCPSocket` which will use
the proxy environment variables to proxy any `TCPSocket`.
The environment variables that proxifier will check are (in order of descending
precedence):
<table>
<tr>
<th>Variable Name</th>
<th>Alternatives</th>
<th>Notes</th>
</tr>
<tr>
<td>proxy</td>
<td>PROXY</td>
<td>Requires the proxy scheme to be present.</td>
</tr>
<tr>
<td>socks_proxy</td>
<td>SOCKS_PROXY<br>socks5_proxy<br>SOCKS5_PROXY</td>
<td>Implies the SOCKS5 proxy scheme.</td>
</tr>
<tr>
<td>socks4a_proxy</td>
<td>SOCKS4A_PROXY</td>
<td>Implies the SOCKS4A proxy scheme.</td>
</tr>
<tr>
<td>socks4_proxy</td>
<td>PROXY</td>
<td>Implies the SOCKS4 proxy scheme.</td>
</tr>
<tr>
<td>http_proxy</td>
<td>HTTP_PROXY</td>
<td>Implies the HTTP proxy scheme.</td>
</tr>
</table>
### Ruby
```ruby
require "proxifier/proxy"
proxy = Proxifier::Proxy("socks://localhost")
socket = proxy.open("www.google.com", 80)
socket << "GET / HTTP/1.1\r\nHost: www.google.com\r\n\r\n"
socket.gets # => "HTTP/1.1 200 OK\r\n"
```
## Supported Proxies
<table>
<tr>
<th>Protocol</th>
<th>Formats</th>
<th>Notes</th>
</tr>
<tr>
<td>HTTP</td>
<td><pre>http://[username[:password]@]host[:port][?tunnel=false]</pre></td>
<td>
The port defaults to 80. This is currently a limitation that may be solved in the future.<br>
Appending <code>?tunnel=false</code> forces the proxy to not use <code>CONNECT</code>.</td>
</tr>
<tr>
<td>SOCKS5</td>
<td><pre>socks://[username[:password]@]host[:port]
socks5://[username[:password]@]host[:port]</pre></td>
<td>
Port defaults to 1080.
</td>
</tr>
<tr>
<td>SOCKS4A</td>
<td><pre>socks4a://[username@]host[:port]</pre></td>
<td>Not yet implemented.</td>
</tr>
<tr>
<td>SOCKS4</td>
<td><pre>socks4://[username@]host[:port]</pre></td>
<td>Currently hangs. Not sure if the problem is with code or server.</td>
</tr>
</table>
