Similar projects - collaboration?

[tony]

Interested in seeing the differences in the following projects? Is there any overlap and / or willing to collaborate? I'd like to avoid duplication / see sharing where possible.

Are there any other vi-like python text editors that fell under the radar?

[stefanoborini]

I'd include my code gladly, but please keep in mind I cannot do it all by myself without prior discussion of what's needed and what's not. What I can provide is both the vaitk PyQt-style design as a generic visual framework (eventually reworked for a more PEP8 style) and the general MVC infrastructure or ideas in terms of responsibilities from vai.

What I can provide already right now is a detailed explanation of the design choices at the base of vai. I do not consider them untouchable, but they work as of now. I am strongly in favor of constant refactoring.

Hi all,

I added the alternatives in the readme.

@stefanoborini Thanks for the offer, I appreciate it! Right now, I'm not sure what can be reused, I'm also not sure how much I'm willing to invest in pyvim in particular. It was more created as a proof of concept to challenge the prompt-toolkit library and to learn.

So, there is no roadmap. But my focus is probably going to be this:

• First, ensure that prompt-toolkit is the best possible libary for creating REPLs.
• Second and third (in no particular order) Implementation of better data structures. (That means probably either rope or gap buffer. Or an adaptation that fits well into Python.) And adding real vt100 pseudo terminal emulation. (like neovim got as well.) The latter will probably allow me integrate a full debugger.

Implementing a better data structure would probably require refactoring many parts of the code base. So, merging code basis is probably not going to be an option for me right now.

Further, looking at Vai, the only things I'm missing right now are the following:

• Highlighting of all occurrences of the identifier currently under the cursor.
• Cursor position restored between runs.
• Autoindent

Actually that would probably be an evening of work for me. (In any case, less than porting it.)

And looking at the key bindings, that's also only a fraction of what we already support in pyvim:

Maybe I'm missing something, I really appreciate your offer, but I'm really not sure what we can merge.
