I want to change how copying/pasting works for a non-leaf node. In particular, I want to render the node as flat text, and on paste parse it using a regular expression.
For example,
"doc": {
"type": "doc",
"content": [
{
"type": "paragraph",
"content": [
{
"type": "text",
"text": "text "
},
{
"type": "math",
"content": [
{
"type": "text",
"text": "y = mx + b"
}
]
},
{
"type": "text",
"text": " moretext"
}
]
}
]
}
should be serialized as text ${y = mx + b} moretext
I created the following toDOM rule for this:
toDOM: (node: ProseMirror.Node) => {
return "${" + node.textContent + "}"
}
My plan is to then use a transformPasted plugin, like the one here to then serialize this back into math, matching on the ${ ... }
regular expression.
Upon trying to do this, though, I get the following error:
I am wondering if there’s a reason for this error other than keeping a dev from shooting themselves in the foot, and if it’s safe to ignore in this case.
