[FR] Set global option for which port serve_site should use

[ulyngs]

Happy new year Yihui!

Sometimes one needs to always use a specific port when serving a site during local development (e.g. an API might only accepts requests from, say, localhost:3469).

It's possible to serve manually from a specific port with blogdown::serve_site(port = 3469).

However, it's not possible (as far as I could tell) to set a port to use in .Rprofile.

It'd be great if it was possible to set e.g. options(blogdown.serve_site.port = 3469) and then whenever serve_site is called, it's serving from that port.

The port can be set with the global option servr.port: https://git.yihui.org/servr/manual.html#sec:man-server_config

I understand that this is not obvious, but the ... arguments of blogdown::serve_site are passed to servr::server_config(), and you can configure the default values of them via servr.* options (or environment variables).

Ah I figured something like that might be the case!

I just submitted a pull request for an edit to this page on the blogdown documentation, which is where I was expecting to find that information when I was searching for it yesterday: #771
