Binary Modules

Binary modules allow you to change or extend the behavior of Pragma without having to change the core source code. Binary modules are written in C++ and loaded during runtime using Lua (with some special exceptions). Some example modules are:

• pr_chromium: Adds an integrated Chromium-based Web Browser to Pragma
• pr_openvr: Adds virtual reality support to Pragma
• pr_bullet: Adds support for the Bullet physics engine to Pragma
• pr_physx: Adds support for the PhysX physics engine to Pragma
• pr_curl: Adds support for the curl library to Pragma
• pr_sqlite: Adds SQLite support to Pragma

Installing Modules

 Binary modules are generally installed to "Pragma/modules/" and can be

prebuilt binaries, otherwise build yourself.

Loading Modules

Binary modules are generally installed to "Pragma/modules/" and can be

local moduleName = "pr_chromium"
local result = engine.load_library(moduleName)
if(result ~= true) then
    console.print_warning("Failed to load \"" .. moduleName .. "\" module: " .. r)
    return
end

moduleName: No "modules/" no lib prefix no extension

Building Modules

 

Custom Modules

Go to the Pragma module template repository on GitHub and create a new repository from it:

You can choose whatever name you want for the repository, but for consistency it is recommended that it should have the same name as the module, which means:

• It should start with the "pr_" prefix
• It should be all lowercase
• It should only contain letters and underscores

Some examples are: "pr_chromium", "pr_bullet", "pr_audio_fmod", etc.

Click "Create repository from template" to generate the repository. The generated repository now contains a bunch of template files, which still need to be initialized. To do so, open the file "template_pragma_module.json" on GitHub and edit the values:

• "name": A pretty name, which will appear in the generated readme.
• "module_name": The internal name of the module (i.e. the name of the CMake target and the binaries). This name should always start with the prefix pr_ and always be lowercase.
• "install_directory": The directory where the module should be installed to, relative to the Pragma installation. This should be somewhere in modules/.

Now commit your changes. This will trigger a workflow which will initialize the repository with the values, which should take about two minutes. Simply refresh the page a few times, once you can see the following icons at the top of the readme, that means the initialization was completed:
