garrysmod_common

A repository of common bits for compilation projects based on Garry's Mod.
The include folder has all the required headers for building modules for Garry's Mod (LuaJIT and Garry's Mod headers) with C++.
There's common code for premake on the premake folder for faster development. premake5 is required to generate projects.

Warning

Do not use internal classes/structures (like the GameDepot::System class or the IGamemodeSystem::Information structure) unless you compile with Visual Studio 2015, Visual Studio 2017 or Visual Studio 2019 on release mode, for Windows.
On Linux, everything should work fine as is, on release mode.
For Mac OSX, any Xcode (using the GCC compiler) version MIGHT work as long as the Mac OSX 10.7 SDK is used, on release mode.
These restrictions are not random; they exist because of ABI compatibility reasons.
If stuff starts erroring or fails to work, be sure to check the correct line endings (\n and such) are present in the files for each OS.

Usage

In your project's premake5.lua (or whatever you named it) you should include your local copy of this repository, for example:

newoption({
    trigger = "gmcommon",
    description = "Sets the path to the garrysmod_common (https://github.com/danielga/garrysmod_common) directory",
    value = "path to garrysmod_common directory"
})

local gmcommon = assert(_OPTIONS.gmcommon or os.getenv("GARRYSMOD_COMMON"),
    "you didn't provide a path to your garrysmod_common (https://github.com/danielga/garrysmod_common) directory")
include(gmcommon .. "/generator.v2.lua")

Creates the workspace with the provided workspace_name, optional workspace_add_debug for including a debug compilation mode (default is true) and optional workspace_path for files (can also be set by premake option (--workspace=path) and by default uses the value in the config file). Must be called at least once before the next functions.

CreateWorkspace({
    name = workspace_name,
    allow_debug = workspace_add_debug, -- optional
    path = workspace_path -- optional
})

Creates the project for the provided state on project_serverside (it's a boolean), optional project_manual_files (allows you to add the source/header files manually through the function files and default is false) and optional project_source_path for source files path (can also be set by premake option --source=path and by default uses the value in the config file, but beware it will be used by all projects).

CreateProject({
    serverside = project_serverside,
    manual_files = project_manual_files, -- optional
    source_path = project_source_path -- optional
})

Call the next functions as needed. The Source SDK based projects do not need a path to the SDK anymore, as it is provided through this git repository as a submodule.

IncludeDetouring() -- uses this repo detouring submodule
IncludeScanning() -- uses this repo scanning submodule

You can also request the project to auto-install the compiled files to a directory selected by you or automatically found on your system. Use one of the following:

Append the --autoinstall flag to your command to either use the GARRYSMOD_LUA_BIN environment var, automatic path finder or the DEFAULT_GARRYSMOD_LUA_BIN_DIRECTORY config (which you have to define yourself in config.lua).
Append the --autoinstall=path config to your command to use the path you want.

Using specific MacOSX SDKs is also supported, by using either the premake config --macosx_sdkroot or the preferred SDKROOT environment variable when calling make.
