pacproxy's Issues

Unable to execute pacproxy_2.0.0_windows_amd64.exe

I just downloaded pacproxy_2.0.0_windows_amd64.exe and when executing it returns

$ ./pacproxy_2.0.0_windows_amd64.exe
panic: open : The system cannot find the file specified.

goroutine 1 [running]:
log.Panic(0xc04206ff20, 0x1, 0x1)
        /usr/local/Cellar/go/1.9.2/libexec/src/log/log.go:326 +0xc7
main.main()
        /Users/williambailey/Development/go/src/github.com/williambailey/pacproxy/pacproxy.go:47 +0x1e7

Are you sure it's correctly built?

Thank you.

ty

thanks for this simple proxy
specially for providing the ARM exe that is static(maybe?) and runs on openwrt.
how do I static compile it for ARM my self?

Add systemd support

Hi! Could you provide unit file to start/stop proxy via systemctl?

Support for SSL proxy

Hello - firstly, thank you for this wonderful app.

I was wondering if it'd be possible to add in support for SSL proxies specified in the PAC file using "HTTPS exampleproxy.com:443" instead of "PROXY exampleproxy.com:80"?

Many thanks

panic: (anonymous): Line 26506:51 Invalid regular expression: re2: Invalid (?=) <lookahead>

I'm trying to use pacproxy to convert shadowsocks pac to simple http proxy, but faced this error.

I actually located some ?='s in the shadowsocks generated pac file:
....
Filter.elemhideRegExp = /^([^\/\*\|\@"!]*?)#(\@)?(?:([\w\-]+|\*)((?:$[\w\-]+(?:[$^*]?=[^\($"]*)?\))*)|#([^{}]+))$/;
....
var candidates = text.toLowerCase().match(/[^a-z0-9%*][a-z0-9%]{3,}(?=[^a-z0-9%*])/g);
....

[Feature Request] support forwarding to a SOCKS5 proxy

This would be a huge gain for browsers without PAC support to use socks5 proxy.

Proxy Basic Auth Header

Would it somehow be possible to send authentication headers to the proxy requests via basic auth? like this:

domain\username , active directy password

http works through pacproxy but https doesn't

Browsing to bing via http:// works, but doesn't via https:// using pacproxy. Using the proxy directly works as intended. The verbose output is below, apologies in advance since I know this isn't much to go by.
