Can I make Markdown headings automatically numbered, instead of just replacing the '#+' with an icon?"

Just like turning

Heading 1......

Heading 1 1......

Heading 2......

Heading 2 1......

Heading 2 1 1......

Heading 2 1 2......

Heading 2 2......

Heading 2 2 1......

into the following format

1 Heading 1......
1.1 Heading 1 1......
2 Heading 2......
2.1 Heading 2 1......
2.1.1 Heading 2 1 1......
2.1.2 Heading 2 1 2......
2.2 Heading 2 2......
2.2.1 Heading 2 2 1......

Yes, you can. The heading.icons value can be defined as a function that returns a string, that returned value is what we'll render for the icon. In that function you have access to a sections property which is a list of integers indicating that index information.

Based on your example here's what you would do:

require('render-markdown').setup({
    heading = {
        icons = function(ctx)
            return table.concat(ctx.sections, '.') .. ' '
        end,
    },
})

You're free to change this however you feel, maybe adding an icon in some cases, changing how the values are joined together, changing the suffix, it's all completely up to you.
