[Bug]: Character Count extension does not count characters correctly when there is mention

[ederssouza-hotmart]

Affected Packages

extension-character-count and extension-mention and suggestion

Version(s)

2.9.1

Bug Description

When using the editor with the extensions @tiptap/extension-mention, @tiptap/suggestion and @tiptap/extension-character-count the character count does not consider the length of the mention, only the @. The error can be reproduced in the mention extension doc itself https://tiptap.dev/docs/examples/advanced/mentions.

Browser Used

Chrome

Code Example URL

Expected Behavior

The character count should be 56 not 44.

Additional Context (Optional)

A mention is an inline node, so it only has a width of one.

The real bug here is that the way that prosemirror does text and the way that tiptap does text is different.

When using .textBetween like the chracter extension does: https://github.com/ueberdosis/tiptap/blob/develop/packages/extension-character-count/dist/index.js#L27
it is unaware that the node can be serialized to text because we do not pass the leafText to the nodespec in prosemirror here:

tiptap/packages/core/src/helpers/getSchemaByResolvedExtensions.ts

Lines 87 to 91 in 045d987

	extensionAttributes.map(extensionAttribute => {
	return [extensionAttribute.name, { default: extensionAttribute?.attribute?.default }]
	}),
	),
	})

Hi, I tried an implementation that resolves this issue on this PR#7071

It uses this.editor.getText() that uses the schema that contains a textSerializer from mention.

If you have the bandwidth to review 🙏

The tests are now counting 56 and not 44.
