@kerebron/extension-automerge v0.0.12

Kerebron extension for collaboration using automerge

Current state (WIP)

WARNING: this extension is currently broken.

Reasons:

• Current peritext algorithm does not support nested block elements https://www.inkandswitch.com/peritext
• Issue on github https://github.com/inkandswitch/peritext/issues/27 As of 2025 this thread was not updated in nest 2 years.
• Proposal for peritext2 has not been implemented yet https://martinkl.notion.site/Block-elements-in-rich-text-CRDT-for-Peritext-2-a3b69f886dbc4ad1abe81cea0b3e6623

I tried naive hacks but got stuck on tables support. The reason is a format of marks in document. Compare below 2 tables:

1. Table with 2 rows, 1 cell each

<table>
  <tr>
    <th>1</th>
  </tr>
  <tr>
    <td>2</td>
  </tr>
</table>

Pseudocode of marks JSON structure:

[
  { "type": "th", "parents": ["table", "tr"] },
  { "text": "1" },
  { "type": "td", "parents": ["table", "tr"] },
  { "text": "2" }
]

2. Table with 1 row, 2 cells

<table>
  <tr>
    <th>1</th>
    <td>2</td>
  </tr>
</table>

Pseudocode of marks JSON structure:

[
  { "type": "th", "parents": ["table", "tr"] },
  { "text": "1" },
  { "type": "td", "parents": ["table", "tr"] },
  { "text": "2" }
]

Currently, both tables produce same output which resulted in folding all tables into 1 row.
