I'd love some documentation about the syntax of the model XML files. At the moment we can only deduce the nodes and parameters from the examples.

The node factory is a good place to start, These will be your toplevel elements.

MarkovJunior/source/Node.cs

Lines 24 to 38 in 222cd2e

Node result = xelem.Name.LocalName switch
{
"one" => new OneNode(),
"all" => new AllNode(),
"prl" => new ParallelNode(),
"markov" => new MarkovNode(),
"sequence" => new SequenceNode(),
"path" => new PathNode(),
"map" => new MapNode(),
"convolution" => new ConvolutionNode(),
"convchain" => new ConvChainNode(),
"wfc" when xelem.Get<string>("sample", null) != null => new OverlapNode(),
"wfc" when xelem.Get<string>("tileset", null) != null => new TileNode(),
_ => null
};

Each node has a Load method which should help deduce what nested elements the node is expecting.

I'm trying to write xsd definitions for xml files.
It looks like VS can automatically load the xsd and display popups.
Of course it is also important to write human-readable documentation.

Some attempts (remarks may not be accurate):

models.xsd

put this at docs/models.xsd

Hi, I am working on a port of Markov Junior project. And I am considering to create a doc for this project. What syntax doc format do you prefer or recommend?

LBroe commented Jun 6, 2022

@aseaday It's supposed to be a programming language, so we need a description of how to write a program with it. What are the keywords and how does the control flow work? I'd just start with a markdown file, because that is the most accessible format.

@aseaday But the syntax is exactly what's missing. We already have a long and thorough readme with links to further information. We just don't know how to write a program with this programming language.

How about Gitbook.

I would recommend GitHub pages.
We can write some md documentation first and then decide how to deploy it.

How about we talk in Documentation and resources #24.
I think we could formally do this thing as a team.

I got you. The explanation of node type and there combination rule is missing.

I have started writing about xml syntax in syntax.md. Hope this helps!
