Using proxy with stack hoogle

[Guanpeng Xu]

Hello,

I want to use stack hoogle through a proxy. Here is what I tried:

$ ~/.local/bin/stack --version
Version 1.6.3, Git revision b27e629b8c4ce369e3b8273f04db193b060000db (5454 commits) x86_64 hpack-0.20.0

$ env | grep proxy
https_proxy=socks5h://127.0.0.1:12800
http_proxy=socks5h://127.0.0.1:12800
no_proxy=127.0.0.1,localhost

$ ~/.local/bin/stack hoogle
Hoogle isn't installed. Automatically installing (use --no-setup to disable) ...
Minimum version is hoogle-5.0. Found acceptable hoogle-5.0.16 in your index, installing it.

Meanwhile these were the connections:

$ sudo netstat -nalp | grep stack

It seems that the env vars were not respected. How to use proxy with stack hoogle?

Hi Guanpeng,

Does it fail if you run without the proxy set? If so, can you paste a
trace with --verbose which includes the failure message? Generally,
the Haskell http library used by both Stack and Hoogle takes care of
http_proxy for you automatically so it's surprising that something
isn't picking it up.

Thanks, Neil

Dear Neil,

Thanks for the tip. In the log I found out the reason. It was because that I enabled nix but did not make the environment impure. By adding pure: false the problem is resolved.
