nuget

For some reason, the only Monogame's resource manager, Pipeline tool, is a total pain in the ass to work with. A lot of stuff which should've been automated is instead painfully done by hand in a crappy UI. After you've dragged and dropped 100 pngs one by one, you come to realization that the Pipeline tool is nothing but tears and sadness.

So what shall we do about all this?

Fear not - Nopipeline comes to the rescue. It's an addon for Pipeline Tool, which generates and updates .mgcb config for you. You can safely add, delete and move around resource files directly in Explorer - Nopipeline will do the rest for you.

Additionally, you can make resource files watch other files! Let's say, you got Tiled map project. It has one main .tmx file and a bunch of textures and tileset files. But Pipeline Tool has referenced only .tmx file, so if you update only texture or only tileset, you have to either update the .tmx or do a manual rebuild, because Pipeline Tool doesn't know about files other than .tmx.

With Nopipeline you don't have to do any of that - just set .tmx file to watch textures and tilesets - and Pipeline Tool will detect and update everything by itself.

Sounds cool and all, but is it compatible with my existing setup/engine/pipeline extensions?

Nopipeline is not a Pipeline Tool replacement - it's an addon. Its only function is to scoop up all resource files and put them into .mgcb config. The rest of the resource compilaton process will go exactly the same. You can add or remove Nopipeline at any point in development, and nothing will break. Nopipeline won't override resources which already exist in the .mgcb config and will leave a perfectly valid config after itself.

Now we're talking. How do I integrate this thing in my project?

First of all, install the Nopipeline.Task via Nuget. After that, you will need a NPL config. NPL config is what Nopipeline uses to generate MGCB config. Nopipeline will generate an empty NPL config automaticaly on first build. After that, you can just delete MGCB config. Yep, that's right, you don't need it anymore - Nopipeline will generate a new MGCB automatically. I also recommend adding your .mgcb files to the gitignore.

Now you need to understand how NPL config works and fill it up with rules so that Nopipeline would know what content goes where. NPL config looks like this:

{
	"root": "../Path/To/Your/Content/",
	"content": 
	{
		"textures": 
		{
			"path": "Textures/*.png",
			"recursive": "True",
			"action": "build",
			"importer": "TextureImporter",
			"processor": "TextureProcessor",
			"processorParam": 
			{
				"ColorKeyColor": "255,0,255,255",
				"ColorKeyEnabled": "True",
				"GenerateMipmaps": "False",
				"PremultiplyAlpha": "True",
				"ResizeToPowerOfTwo": "False",
				"MakeSquare": "False",
				"TextureFormat": "Color",
			}
		},
		"specificFile": 
		{
			"path": "Path/To/File/specificFile.txt",
			"recursive": "False",
			"action": "copy",
		}
	}
}

It is essentially a JSON. Config above has two content rules: textures and specificFile. Each rule describes one specific resource type. Rules can affect entire directories or specific files.

Let's look at an each parameter:

There is also an optional watch parameter. Its usage looks like this:

{
	"content": 
	{
		"spriteGroup": 
		{
			"path": "Graphics/*.spritegroup",
			"recursive": "True",
			"action": "build",
			"importer": "SpriteGroupImporter",
			"processor": "SpriteGroupProcessor",
			"watch": 
			[
				"Default/*.png",
				"Default/*.json",
			]
		},
	}
}

With watch parameter present, all the .spritegroup files will be built by Pipeline Tool, if any .png or .json file will be changed. Note that all the paths listed in watch are relative to the main path, so final paths will look like this: Graphics/Default/*.png.

But that's not all. Nopipeline also provides an extended reference management. Add references section into your .npl config like this:

{
	"references":
	[
		"%PROGRAMFILES%/YourLibDir/Library.dll",
		"RelativePath/RelativeLibrary.dll",
		"OtherPath/*.dll",
	],
	"content": 
	{

	}
}

With Nopipeline you can use environment variables like %PROGRAMFILES% - something Pipeline Tool can't do by itself. If referenced libraries are missing, Nopipeline will delete their entries from config. Additionally, you can add references the old way from the Pipeline Tool - Nopipeline will not delete them unless the files themselves don't exist. References also support wildcards just like normal file paths.

With NPL config done, save it in the same directory as MGCB config and give it the same name. For example, if your MGCB config is named Content/Content.mgcb, your NPL config should be Content/Content.npl

You can also include NPL in Visual Studio project, if you want.

If you want more seamless pipeline-forgetting experience, you can check out Monofoxe Engine, with Nopipeline integrated out of the box.

Running the sample.

Before running the sample, build Nopipeline.Sample.Content project. This will build the custom pipeline extension.

All the other stuffs.
