Mermaid diagram

We can target Mermaid's flowchart as an output format. And this is what it looks like:

graph LR
  node_0xc0001229c0["operator: -"]:::custom_operator;
  node_0xc000122900["operator: +"]:::custom_operator;
  node_0xc0001229c0 --> node_0xc000122900;
  node_0xc000122840["operator: *"]:::custom_operator;

JSON

We can target JSON as an output format. The format of each node is a bit verbose but straightforward:

{
    "role": "{{NODE NAME}}",
    "ATTRIBUTE_1": "VALUE_1", 
    ... 
    "ATTRIBUTE_N": "VALUE_N",
    "children": [ 
        ...
    ]
}

And this is what it expands into:

{
  "role": "operator",
  "syntax": "infix",
  "name": "-",
  "children": [
    {
      "role": "operator",
      "syntax": "infix",
      "name": "+",
      "children": [
        {
          "role": "operator",
          "syntax": "infix",
          "name": "*",
          "children": [
            {
              "role": "number",
              "value": "2"
            },
            {
              "role": "operator",
              "syntax": "infix",
              "name": "*",
              "children": [
                {
                  "role": "number",
                  "value": "100"
                },
                {
                  "role": "number",
                  "value": "100"
                }
              ]
            }
          ]
        },
        {
          "role": "number",
          "value": "100"
        }
      ]
    },
    {
      "role": "number",
      "value": "1"
    }
  ]
}```

## YAML

We can target YAML as an output format. The format of each node is
a bit verbose but easy to understand.

```yaml
role": "{{NODE NAME}}",
ATTRIBUTE_1: VALUE_1,
...
children": 
- ...
- ...

And this is what it expands into:

name: "-"
syntax: infix
children:
- role: operator
  name: +
  syntax: infix
  children:
  - role: operator
    name: "*"
    syntax: infix
    children:
    - role: number
      value: 2
    - role: operator
      name: "*"
      syntax: infix
      children:
      - role: number
        value: 100
      - role: number
        value: 100
  - role: number
    value: 100
- role: number
  value: 1
