[wip] feat: add "Copy as document" to copy rich markdown into emails and documents

[bensu]

I will often write something in Logseq that I want to send via email or make part of a Google Doc / Dropbox Paper. "Copy as TEXT" has two problems:

• It gives me the contents of only one block and not its children
• It gives me content in markdown format (_foo_ instead of foo) and then I need to transform it manually

I added "Copy as DOCUMENT" that changes both of those things. IMO, this should be the behavior of "Copy as TEXT" but maybe others use it differently and have other expectations.

Note that Copy as Document only gives you rich text when you paste into an editor that can handle it. Otherwise, it gives you the same format as Copy as TEXT but with the children contents

TODO in this PR

• Handle embeds
• Handle references

I'll probably need to change mldoc in order to handle the two outstanding TODOs

hi @bensu, I'm working on block-level export feature now

• exporting a block will include itself and its childs
• replace embed&block-references with related contents
• but not working on block-level html exporting yet, so excited about this PR.

And for replace embed & refs, related mldoc source:

• replace_embed_and_refs
  https://github.com/logseq/mldoc/blob/f81a18f8dc6165708643d3a6d94929b60deb1897/lib/syntax/tree_type.ml#L385

• feat: export md with different indent styles mldoc#75

Cool! In that case, let’s bench this PR until you are done with that feature and then we can see if there is a good way to translate the work you did for an HTML export.

@bensu both PRs are merged now, let us know if you need any help on mldoc.

hi @bensu, I'll start updating some implements of html-export in mldoc recently. Will update infos in this issue

Hi @bensu , here is the PR for "export as html": #2496

Closing this since "Copy as text/HTML/OPML" is supported now.
