Helix: A post-modern text editor
https://helix-editor.com/Surprisingly, it didn’t take that long to update my Vim muscle memory. Days or weeks, maybe? However, I still have mixed feelings about modal editors in general, and most of my gripes with Helix are actually about modal editors and/or console editors in general.
Code folding is a feature I’m still waiting for.
I have reload-all bound to Ctrl-r
Another option you may want to try is mux (github.com/coder/mux). It wraps the LLM in a nice interface which has the ability to do line/block comments on changes by the LLM that then goes goes into your next prompt. It’s very early stage though: v0.19.0.
How do other editors do this, if they don't use LSPs? Helix specifically choses LSP as the integration mechanism (in combination with TreeSitter) for supporting different programming languages, because it is a language-agnostic protocol and therefore only needs to be implemented once. Is there some established AI-agnostic protocol/interface? I don't think MCP would work here?
"Within C++, there is a much smaller and cleaner language struggling to get out."
Helix carries a baggage of ideas from Vim. It does not have consistent and transferable keybinds. It does not have composition of ideas:
You can move to the next line in the buffer editor with `k` but to move down to the next line in the file explorer you have to do `ctrl+n`?
Vim is like C, Helix is like C++ and Ki Editor is like Rust.
I've never used Helix, but this exists in vim too, but it the autocompletion, because in that context hitting k would type k. Makes sense right? I'm guessing hitting k in Helix file explorer has a similar use, maybe searching?
I see the "Why Ki?", and then it has this:
> Being first-class means that it is not an extra or even sidekick; it is the protagonist.
Eh.
I find it quite off putting.
I guess my expectation is that someone enthusiastic enough to write a text editor with a value proposition of "it's got good tree-sitter-based navigation" would want to discuss why they thing syntactic selection is neat.
Seeing cliche LLMisms doesn't signal the same level of care to me.
You can just… not update them.
I do find Helix very impressive. I remember the Python LSP working without any configuration whatsoever.
However, I have vim muscle memory built over 25 years of use. I already struggle switching between Emacs and vim (or its equivalents) - for example, after a period of vim usage, I would press ESC repeatedly in Emacs, three of which are enough close a window. While Helix borrows modal editing from vim, it introduces subtle (and meaningful - I have to admit) variations, which unfortunately wreaks havoc with my muscle memory. Maybe the worst part about muscle memory is that unlearning is almost impossible. My dilemma, not Helix's fault...
For the last two weeks, I was forced to work at a normal keyboard. After initial pain for one day, I got back to typing at normal speed. Without losing my comfort with the ergonomic one. I can now just context switch. It wasn't easy though.
Perhaps you will also become comfortable with both vim and helix after the initial struggle?

Me too and it took a view attempts but I'm on Helix now and don't regret it. Once you are over the most prominent discrepancies like dd and G it's an uphill battle.

However, after a few weeks, I ended up rewriting things to be more classic VIM-like after all. This might have just been muscle memory refusing to yield, I am not sure. One thing I remember though, was that the multi-cursor+selection approach only really helps when you can see everything you're about to change on the screen. For large edits, most selections will be out of the scroll window and not really helping.
I still haven't written it off completely, though with AI I increasingly find myself writing more prose than keywords and brackets, so I am not sure it's going to feel worth it.
That's why the Ki editor has a feature called Reveal Cursors (https://ki-editor.org/docs/normal-mode/space-menu#-cursor-re...), which is specifically made to solve this issue
Which is still a net positive over the alternative?
My vim muscle memory is too strong and stubborn.
I tried it out for a few days, and I cannot justify spending time on this when I am already very productive with vim/VSCodeVim. Helix is nice in many ways but not worth switching over
For sufficiently complex manipulations, I find the "selection-action" ("motion-action") to be more intuitive than "action-motion". Even with vim, I'd often like making use of visual mode.
I think the main limitation to this that I believe is it's probably a bit slower for quick + frequent edits compared to vim.
"Move to end of the scope" or "insert after this expression" and similar.
The overlap between languages should be large enough to make this feasible.
> Post-modern?!
It's a joke. If Neovim is the modern Vim, then Helix is post-modern.
> Is it any good?
Yes.I think 29MB is still huge for a terminal text editor, but nevertheless not "hundreds".
