- Dummy server
  - [ ] send an empty void
  - [ ] send a surface to stand on
  - [ ] handle chat
- NBT library
  - [x] parse NBT

## Project Setup Instructions

### Prerequisites:

Build dependencies:

- bash
- a C++ 20 compiler
- GLFW with headers

Setup dependencies:

- wget or curl
- gzip
- sha256sum (or NetBSD's sha256, hashalot's sha256 will not work)
- tar
- a C compiler (for sockpp)
- CMake (for sockpp)

**For people using other shells than bash:** You need to at least have bash
installed to use the scripts, but using it as your shell while working on
this project also allows you to use the provided aliases.

If you don’t want to use bash as your shell, not even temporarily for this
project, you can use the scripts by running them from the project's base
directory and run any generated executables with `LD_LIBRARY_PATH` set to
point to `bin/lib`.


### Setup

- `git clone` this repository
- if using bash:
  - `source` the file `setupenv.bashrc` from the project's base directory
    to load the provided shell environment (local customizations to the
    environment can be placed in a fiile `.localenv.bashrc` in the project's
    root directory if necessary)
  - `setup_project`
- if not using bash or not using the provided environment:
  - `cd` to the project's base directory
  - `scripts/setup_project.sh`

This will download (and build if applicable) the following dependenceis:
- [tiny-utf8](https://github.com/DuffsDevice/tiny-utf8)
- [sockpp](https://github.com/fpagliughi/sockpp)

### Building

To build the project, just use the `build` alias or invoke `scripts/build.sh`
from the project's base directory.

For more details, have a look at [the build system documentation](doc/build_system.md).
