Pasting text with newlines

[eivindw]

I have a problem that I could need some help on. We have the latest Plate version setup with the code-block plugin. When I paste content with line breaks inside a code-block section - for example content like this:

test
some
  text
with line breaks

The editor splits the content into separate blocks instead of just adding it to the code-block as is:

I suspect I am missing some basic stuff in the editor setup - but cannot figure out what. I see the same effect when pasting the same content into an empty paragraph. I would expect one paragraph with soft breaks - but get one paragraph for each element:

I see the Plate playground behaving like I want - not splitting into several paragraphs:

Anyone have any idea what I could be missing? My main problem is with the code-block, but I think the problem is with the base setup since we observe the same behavior in paragraphs. So something in the way pasted content is interpreted? We are using HTML deserializing - but the behavior seems to be the same with plain text content.

Our code is hosted on a secure network - so difficult to show the whole setup.

I think it's due to the deserializers. Could you try using the same ones than the playground to confirm that?

[eivindw]

That would be using the same set of plugins as the playground? Or is there any deserializer setup outside the plugins?

createDeserializeDocxPlugin(),
createDeserializeCsvPlugin(),
createDeserializeMdPlugin(),
createJuicePlugin(),

– and/or disable any other deserializers

Thanks for the pointers. Tested with all deserializers, but that did not fix stuff. Probably something weird in our setup. Found a workaround by just pasting as plain text if selection is in a code block:

      editor.insertData = (data) => {
        const selected = someNode(editor, {
          match: { type: getPluginType(editor, ELEMENT_CODE_BLOCK) }
        });

        if (selected) {
          editor.insertText(data.getData("text/plain"));
        } else {
          insertData(data);
        }
      }

plate/packages/code-block/src/deserializeHtmlCodeBlockPre.ts

Line 5 in aa6538b

export const deserializeHtmlCodeBlock: DeserializeHtml = {

This deserializer is probably not called for some reason. You could just map \n to code lines as done in that file.
