VisualEditor/Change markers
 | This page is obsolete. It is being retained for archival purposes. It may document extensions or features that are obsolete and/or no longer supported. Do not rely on the information here being up-to-date. VisualEditor no longer has change markers, as Parsoid does not require them any more. |
Informal (well, pretty informal) summary of the change markers format.
Generally, the format is a JSON object like {"new":82,"content":34,"annotations":15}. The numbers don't really mean anything, if the property is set in the object then it means that that sort of change occurred in the marked node. The JSON object is placed inside the node's data-ve-changed attribute, so it would ultimately look something like <p data-ve-changed="{"new":82,"content":34}">Something here has changed!</p>.
| Change marker | Meaning |
|---|---|
| new | This is a new node, so there won't be any record of it in the old page revision. |
| content | The text of this node has changed. |
| annotations | There are annotations (things like italics and bolds) in this node, and their content has changed. |
| childrenRemoved | There are some children of this node that were removed. |
| attributes | This node's attributes changed. |
| rebuilt | Something changed and the VE couldn't determine what it was. |
