Status update for MoonGem - Gemini server with inline Lua scripting

panda-roux <contact (a) panda-roux.dev>

Hope you're well!

A couple of weeks ago I sent out a notice regarding a piece of Gemini 
server software I'd developed.? This is an update in regards to how that 
project has been progressing.

I'm considering MoonGem to be "basically finished" for now. There are a 
couple of luxuries I'd like to add, but it's essentially 
feature-complete as far as I'm concerned.

As of version 1.3.1, the following features have been added in addition 
to refactoring and code cleanup:

Scripting API features (and corresponding Lua method signatures):

  * Input handling
      o HEAD:get_input([prompt])
      o HEAD:get_sensitive_input([prompt])
  * Specifying a language header part
      o HEAD:set_lang(<language>)
  * Client certificate handling
      o HEAD:get_cert([prompt])
      o HEAD:has_cert()
      o Currently a fingerprint and not_after fields are captured.

Server features:

  * Buffered responses for non-gemtext files (i.e. static files are sent
    piecemeal)
  * Specify a non-standard port via the MOONGEM_PORT environment variable
  * Sanitized URI paths
  * Proper request logging
      o Example: [::ffff:127.0.0.1:54502] /moongem | 32 header + 3639
        body bytes sent (total: 3671)
  * Request pipeline logic that can be interrupted by script method
    calls requiring an irregular response code
      o i.e. if a script calls HEAD:get_input() and there's no input in
        the request URI, the server will drop what it's doing and return
        a 1X code (and prompt META) immediately.

The following are nice-to-have features that I would like to add in the 
future:

  * Automatic directory listing
      o Implementing this in Lua is trivial but it'd be nice to have the
        server handle it
  * Expose more information from client certificates to the scripting API
  * Rate-limiting
  * Some sort of mechanism for response caching
      o Not worth the headache of trying to do this correctly at the moment
  * Some sort of fancy URI variable binding (thinking of ASP.NET's
    routing, e.g. "/posts/{postId}/{commentId}")

Thank you for reading!? Any and all feedback is appreciated.
