other URL schemes

[Johann150]

💡 Summary

Only http or https URL schemes are recognized. According to the WHATWG specification, many more schemes are possible (mailto, irc, gemini, ...): [a-zA-Z] [-a-zA-Z0-9+.]* ":"

👉 current specification about URL scheme (⎇日本語)

Understanding all possible URLs in normal text could lead to too many links. My idea would be to understand other URLs only in altUrlFormat and linkUrl (but not in urlFormat).

🙂 Expected Behavior

oops:url
<gemini://example.com>
[send email](mailto:[email protected]?subject=test)

↓

[
  {
    "type": "text",
    "props": {
      "text": "oops:url"
    }
  },
  {
    "type": "url",
    "props": {
      "url": "gemini://example.com",
      "brackets": true
    }
  },
  {
    "type": "link",
    "props": {
      "silent": false,
      "url": "mailto:[email protected]?subject=test"
    },
    "children": [
      {
        "type": "text",
        "props": { "text": "send mail" }
      }
    ]
  }
]

For a list of URL schemes, maybe we could use https://www.npmjs.com/package/schemes but it does not contain any information about the "security" of a URL scheme.
