Make cgit go gettable

go get git.icyphox.sh/* works!

go get requires the presence of the go-import meta tag1 on the repository’s web page. cgit doesn’t support it out of the box; instead, we can make nginx inject it into every page. Enter: sub_filter.2

sub_filter is a function that simply performs a string replace. For example:

location / {
  sub_filter '<img src=dog.png>' '<img src=cat.png>';
  sub_filter_once on;
}

In our case, we want to have the meta tag injected inside <head>.

server {
  listen 443 ssl;
  server_name git.icyphox.sh;

  location / {
    ...

    sub_filter '</head>'
      '<meta name="go-import" content="$host$uri git https://$host$uri"></head>';
    sub_filter_once on;
  }
}

The closing </head> tag gets replaced — injecting the meta tag inside <head>. This can also be extended to add the go-source meta tag as well.
