Disable plugin on condition

[zerismo]

My appendTransaction method is just initializing marks on text and paragraph nodes, similar to this:

Initializing paragraph with styles

following a lead from https://discuss.prosemirror.net/t/adding-style-on-the-fly/703/11I came up with this plugin: appendTransaction(trs, oldState, newState) { if (trs.length !== 1 || trs[0].steps.length !== 1 || !trs[0].steps[0].slice.content.firstChild || trs[0].steps[0].slice.content.firstChild.marks.length > 0) return; const { fontFamily, fontSize } = getCurrFont(); const schema = trs[0].doc.type.schema; const familyMark = schema.marks.fontFamily.create({ fontFamily }), sizeMark=schema.…

Now when I paste, this plugin makes everything initialize with default marks, which I don’t want.

I can possibly formulate the changes if there is a paste transaction. How do I get to know if a transaction is a paste event or not?

Thanks
