proxy plugin
The proxy plugin provides a couple helper functions to those of us who are stuck behind HTTP/HTTPS/FTP proxies that require authentication. The variables it exports are used by many command-line and GUI applications on Linux, as well as MacPorts and Homebrew on OS X.
Both uppercase and lowercase versions of the proxy environment variables are set, some applications are case sensitive. If you'd like to learn more about the use of these variables, this Arch Wiki Article is a good place to start.
Usage
In all cases you will need to add 'proxy' to your fish_plugins list in config.fish
No authentication
If you just want to have the proxy plugin configure all the environment variables, you may set proxy_host:
set proxy_host myproxy.example.com:8000
The proxy plugin will prepend http:// for you. Here's the result:
~> set -x |grep proxy
ALL_PROXY http://myproxy.example.com:8000
FTP_PROXY http://myproxy.example.com:8000
HTTPS_PROXY http://myproxy.example.com:8000
HTTP_PROXY http://myproxy.example.com:8000
all_proxy http://myproxy.example.com:8000
ftp_proxy http://myproxy.example.com:8000
http_proxy http://myproxy.example.com:8000
https_proxy http://myproxy.example.com:8000
With authentication
Set your proxy host and username:
set proxy_host myproxy.example.com:8000
set proxy_user mylogin
When you need to make use of the proxy, just run proxy. It will prompt you
for a password and setup your environment.
If you didn't setup a proxy_user variable, you will be prompted for a username.
If you wish to clear your proxy variables, run noproxy.
