#+title: Gemenon.jl -- A Gemini Server

* What is it

Gemenon.jl is a server for the [[https://gemini.circumlunar.space/][gemini]] protocol.

It's written in [[https://julialang.org/][Julia]].

* How to use

The usage is quite simple and similar to [[https://github.com/JuliaWeb/HTTP.jl][HTTP.jl]]

First, import the library
#+begin_src julia :tangle server.jl
using Gemenon
#+end_src

Then, setup the SSL config
#+begin_src julia :tangle server.jl
  const verify_callback(preverify_ok, x509_ctx)::Cint = 1

  function init_ssl_context()
      ctx = Gemenon.OpenSSL.SSLContext(mode = Gemenon.OpenSSL.ServerMode)
      Gemenon.OpenSSL.ca_chain!(ctx, "./cert.crt", "./key.key")

      Gemenon.OpenSSL.set_options!(ctx, Gemenon.OpenSSL.SSL_OP_NO_SSLv3)


      accept_all = @cfunction(verify_callback, Cint, (Cint, Ptr{Cvoid}))

      Gemenon.OpenSSL.set_verify_mode(ctx, Gemenon.OpenSSL.VERIFY_PEER, accept_all)
      ctx
  end
#+end_src

You are ready to listen for connections!
You can do this like in Mux.jl

#+begin_src julia :tangle server.jl
  @app test = (
      req -> document(req.conn, """
  # Welcome to Gemenon!

  You can discuss about this on
  => gemini://nixo.xyz/ The Gemenon-Powered Anonymous Board
  """))

  serve(test, init_ssl_context, Gemenon.Sockets.ip"0.0.0.0", 1965)
#+end_src
