Great project, I used it for an online code editor a couple of years ago.

My question is; what's the status of mobile/touch support? It used to be barely usable on touch devices. How is touch support vs Atom? I haven't followed this in years so apologies!

We use CodeMirror for our 8-bit retrodev IDE, and have been pretty happy with it: http://8bitworkshop.com/v3.1.0/?=&file=examples%2Fbrickgame&...

We haven't even scratched the surface with customization beyond adding some more editing modes (fortunately a Z80 mode is already part of the release!) and doing custom gutters and line widgets.

There haven't been very many surprises, notably a performance issue with forced reflow when gutters are overwritten (solution: don't do that) and some vertical div sizing problems, which shows how difficult this kind of project is to do right. Performance has always been stellar, though, even on an underpowered Chromebook.

+1 to Typescript, we've also been converting our IDE over to it :)

When the demo embedded in a fundraising pitch supports Emacs keybindings, I donate. Simple as that.

I have to ask what is probably a dumb question. Why? I used CodeMirror on three projects. It was great. Now I use Monaco aka Visual Studio Code. What would CodeMirror offer ?

I welcome competition in this space but two guys competing with Microsoft seems like impossible to win. Hopefully they get the funding and we can see what they can build

Monaco is maintained by a single guy from my understanding: https://github.com/Microsoft/monaco-editor/graphs/contributo...

It just shows many contributors but looking at code commits and general activity (maintainers) in issues only Alexandru Dima comes out.

Thanks for your work Marijn! I've never developed with CodeMirror before but have used it in IPython notebooks.

I'm sure there are multiple ways open source projects can raise money but one idea I'm fond of is a paid "course". Basically this amounts to a couple hour tutorial. It helps gain users and present a deeper insight into the project while generating income.

Monaco isn't exactly the easiest editor to extend. For those wanting to do custom editor functionality, it still feels like there's a ton of room for other implementations.

yeah Monaco is a code editor. CoreMirror can easily and nicely function as an "editor" in general. I used it in a big project for a specific kind of markdown editing experience. I checked out Monaco at the time and CodeMirror and CodeMirror was WAY easier to setup and integrate into my app.

How will this affect ProseMirror development? Do you see ProseMirror at a point where it can be considered stable enough that it doesn't need a lot of attention?

Yes, ProseMirror is quite stable and it is well-used. Marijn released version 1.0 nearly a year ago and since then we made some improvements, but the interface seems good enough that we didn't even discuss making a breaking change in a component as far as I know. There's not too much maintenance work necessary either, since bug reports are usually pretty good and far fewer than for example with CodeMirror. I think how happy we are with ProseMirror and maintaining it is a major motivation for making these huge changes with CodeMirror, too.

Improving mobile, touch and screen-reader support are from a user perspective the main reasons we are doing this in the first place. We are expecting to support most of the input behavior such platforms provide.

The page doesn't tell me anything on how to contribute code.

Except for small drive-by contributions (see GitHub repo) the project is not in a state were we can really integrate other people in our process, and there will be pretty substantial changes to interfaces. Looking at ProseMirror, contributions will probably mostly include separate modules and not so much work on the actual core (which is pretty stable). This is especially true for CodeMirror where there will be a lot of modes, addons, themes and keybindings, which we are not planning on maintaining as part of the core project.

Oh hi, I'm Marijn, one of the maintainers. It doesn't look like this submission is going anywhere, but I'll keep an eye on the comments and respond to questions.

Hi Marijn. Big fan of ProseMirror. Would you look at building CodeMirror on top of (or at least sharing code with) ProseMirror so both projects can benefit from the effort?
