PacGen: Pac file generator written in Python

If you use multiple proxies and you want to define rules to set specific proxy per specific host, this package can help you. Simply create a ~/.pacgen.yml config file and define your rules there. After that run updatepac command in your terminal and it will create ~/.proxy.pac

Installation

    pip install pacgen

Sample ~/.pacgen.yml

proxies:
  ssh_tunnel: socks5://127.0.0.1:1081
  shadowsocks: socks5://127.0.0.1:1080
  httpproxy: http://127.0.0.1:1082
routes:
  172.19.20.10: ssh_tunnel
  youtube.com: shadowsocks
  viemo.com: shadowsocks
  news.com: httpproxy
# default_proxy will be used for hosts which are not defined in routes.
default_proxy: shadowsocks
# here we define hosts that we don't want to use proxy for them.
excludes:
  - bank.com
  - lastpass.com

Note

Unfortunately, Chrome will not work anymore with a local PAC file path. As a workaround, you can serve it yourself with a webserver like nginx.

sudo apt install nginx
sudo cp ~/.proxy.pac /var/www/html/proxy.pac

Then put this address in your proxy setting:

http://localhost/proxy.pac
