C Module

C Module is a Package type that allows extending the functionalities of nanos world Scripting API

C Modules allows you to extend the functionality of the nanos world scripting API on the server side. Derzeit werden nur C-Module unterstützt.

This is an advanced procedure so instabilities and even crashes may occur.

Creating your C Module binaries​

To create your own module, fist make sure you have Visual Studio installed with Desktop development with C++ (and CMake) or any other C compiler on Linux.

First Steps​

  1. Then, clone our example module in your computer to get start with it.
  2. After cloning, you will need to download it's submodules with git submodule update --init --recursive - this will download the module-sdk as a git submodule into deps/ folder automatically.

Understanding the example​

The important file is under src/example.cpp:

https://github.com/nanos-world-modules/module-example/blob/main/src/example.cpp

Compiling your C Module​

To compile the example, follow the steps:

  1. Create a folder called build/: mkdir build.
  2. Enter the build folder: cd build.
  3. Run cmake ...
  4. Build it with cmake --build . --config Release

And now you will have the dlls/libs in build/Release folder.

Creating a C Module Package​

First of all, create a new Package of type c-module, and add your .dll and .so files into the Package's root folder. Beispielsweise könnte dies wie folgt aussehen:

Packages/
└── my-module/
├── Package.toml
├── example.dll
└── ...

Then make sure to add example (or the name of your dll file) to the Package.toml configuration section:

# c module configurations
[c_module]
# list of binaries paths to load (without extension)
binaries = [
"example",
]

Loading and Using your C Module​

Now you can load the package you created as usual, by adding it to the Config.toml's list of Packages requirement or by adding it to another Package's Package.toml as dependency as well.

And in your Package, you can load and use it like:

-- Calls the module function 'test'
-- Will print 'Hello World' on console
Console.Log(example.test())
