naev_net

Simple library for HTTP-based networking, made for Naev game.

Adds SDL_net as dependecy.

Configuration is at beginning of net.c file.

File main.c contains basic example.

Basic idea is like this :

• You send commands to HTTP server, where script (currently in PHP) will process them
• You get Lua code as response
• You run said code inside Naev Lua interpreter

What this can be used for :

• Postal service
• Guilds
• Guild vaults
• Online features in general
• etc.

Possible limitations :

• It's slow (protocol/hosting-wise), so no real-time
• It's HTTP not HTTPS - maybe not an issue
• ASCII only for now ? - pressumed, not checked

Server

Currently there is simplified forth system interpreter on server side.

How to forth (tldr) :

• you send 1 2 add prt, server reads it word by word
• 1 is number - put it on stack
• 2 is also number - on stack it goes
• add is function - call it
  • it will take two items from top of stack (first 2, then 1)
  • adds them
  • puts result (3) on top of stack
• prt is also function call it
  • it will print first thing from top of stack (3 in this case)

Word list

• add - adds two numbers
• sub - substarcts two numbers
• mul - multiply two numbers
• div - divide two numbers
• mod - modulo of two numbers
• prt - print item on top of stack to output
• motd - prints Message Of The Day
• autoreg - generates access key and make file for it
• getkey - generate random key of given length

Todo

Some ideas on how to progress.

Autoreg

Automatic pilot registration. Gets access token to user.

• Game starts (or is loaded)
• Check if save contains access key
• If not, send 'autoreg prt' command to server
• Save returned key and use it from now on

Other approach to server execution ?

Is interpreter a good way to go?

It is small and offers flexibility.

But I may just overthought it.
