Modules Example Project

This is an example of a Rojo-powered project that uses Modules as a dependency. Like Modules itself, this project also uses GNU make (Makefile) to build the project. Although it's not required, using make makes it easy.

How the dependency works

Here's how Modules is included in this project as a dependency:

1. The Modules repository is added as git submodule.
2. The Modules.rbxmx file is built first: the Makefile is run by invoking make. It recursively invokes Modules' Makefile.
3. This project is built second: the file default.project.json is built using rojo from within the Makefile. It includes built Modules.rbxmx into ReplicatedStorage after Modules is built.

Creating and adding other dependencies

Setting up a dependency

You should first make your dependency into a git repository so it can be added as a submodule later. Assuming you put your code into a src directory, this simple Makefile like this should be useful:

OUT_FILE = MyLibrary.rbxmx
ROJO_PROJECT = default.project.json

$(OUT_FILE) : $(shell find src -type f)
	rojo build $(ROJO_PROJECT) --output $(OUT_FILE)

Note: the $(shell find src -type f) here specifies that the OUT_FILE depends on all files within the src/ directory.

Adding a dependancy

Once you have your dependency repository set up nicely, you can add it to this example project by following these steps.

1. Add the git repository for your dependency as a git submodule (file path works too, but you probably should have it online):

   $ git submodule add https://github.com/You/MyLibrary lib/MyLibrary

2. Add the rbxmx file to the DEPS variable in the Makefile (hint: use \ to use multiple lines). make will be recursively invoked in the directory containing your dependency (below, lib/MyLibrary).

   DEPS = lib/Modules/Modules.rbxmx \
          lib/MyLibrary/MyLibrary.rbxmx
   

3. Include the dependency in this example's Rojo project via an instance description by pointing $path to the resulting rbxmx file (remember, this path is relative to the project file).

                   "$path": "lib/MyLibrary/MyLibrary.rbxmx"
               }
           },

               "$className": "ServerScriptService",
               "MyProject": {
                   "$path": "src/ServerScriptService"
               }
           }
       }
