I'm currently experimenting with CodeMirror for one of my projects, and it shows that you spent a lot of time to refine its design and API. You did an awesome job, seriously.

I haven't tried ProseMirror yet, but I'm pretty sure that the same level of quality is there.

Thanks for your work!

This looks awesome! I'm a big fan of CodeMirror and I will definitely play with this tool as well.

Quick note: the Markdown example page (http://prosemirror.net/examples/markdown/) has a javascript error that's keeping the editor from loading.

Thanks for all your hard work.

Markdown demo should be fixed now, thanks!

I just wanted to say thanks for this (and for Codemirror.)

I haven't released a product using this yet (although I hope to) but I really want to congratulate you for writing something that focuses on a narrow yet hard problem, that a lot of folks would consider uninteresting because it's been "solved" in other domains, and just doing a really, really good job.

Seeing an issue on Chrome 61 on http://prosemirror.net/ : If I highlight some text in the example editor and click the link button, the 'Create a link' box displays at the bottom of the page.

Thanks for letting me know! I was failing to include a CSS file—should be better now.

Glad I could help! Also seeing an issue where the editor isn't loading on http://prosemirror.net/examples/markdown/

Thanks once more -- that was another build problem.

Thanks for all the work you've put in to this. I'm actually using this on a moderately large project at work and it's been a dream to integrate and learn.

That's great to hear! Learning curve is definitely something that's tricky with a library like this (big, modular, with concepts that are unfamiliar to many), so I've tried to compensate with consistency and lots of documentation.

In theory, would ProseMirror work well as the foundation for a code editor (instead of CodeMirror)?

No, it wouldn't. That requires a completely different set of features (gutters, syntax highlighting, etc).
