# A C++ Gemini server

## Introduction

As I saw other implementations in Rust but no C++ to compete, I felt that I had to do something ;-). It is also a chance for me and a friend (
Brumaire) to practice C++ and to try to get as much performance as possible (my speciality is HPC so… Yeah).

## Design

I use PlantUML to do the class diagram for the design. It's a work in progress.

## Goal

What we want is a high performance server using asynchrony at first, and then maybe multi-threading to have the maximum possible performance.

## Configuration

**WIP**
The configuration of the server is made through a JSON file `config.json`. The JSON parser is [simdjson](https://github.com/simdjson/simdjson)
directly integrated in our source code.

### Structure of the file

- content
  - path : string, folder to the content of your site.
- cache
  - enable_cache: bool, to enable cache of files or not
  - cache_size : unsigned int, the maximum size in bytes to put in cache
- ssl
  - pem_path : string
  - cert_path : string

## Dependencies

It uses a bundled version of `spdlog` as a git submodule, but it does not use the `fmt` lib that is inside `spdlog` (you can still change it in the
CMakeLists).

## Documentation

The doc of the code is made with [doxygen](https://www.doxygen.nl/), the `Doxyfile` is at the root of the repo.

## TODO/features

* Possibility of an applicative gateway (like CGI for example)
* Content in RAM cache
* Asynchronous (boost ASIO deals with it)
