helix-editor/helix

A post-modern modal text editor.

A Kakoune / Neovim inspired editor, written in Rust.

The editing model is very heavily based on Kakoune; during development I found myself agreeing with most of Kakoune's design decisions.

For more information, see the website or documentation.

All shortcuts/keymaps can be found in the documentation on the website.

Troubleshooting

Features

• Vim-like modal editing
• Multiple selections
• Built-in language server support
• Smart, incremental syntax highlighting and code editing via tree-sitter

It's a terminal-based editor first, but I'd like to explore a custom renderer (similar to Emacs) in wgpu or skulpin.

Note: Only certain languages have indentation definitions at the moment. Check runtime/queries/<lang>/ for indents.scm.

Async formatting

Whenever I save a file (:write) with LSP enabled (e.g., solargraph for Ruby or rust-analyzer for Rust) the editor halts for 1-2 seconds until finally finishing. This behaviour isn't present when LSP is disabled.

Project goals?

I wonder what are the project goals of helix. I have used quite a few editors, vim, neovim, vis, kakoune, doom emacs but I wonder what are the goals of this project? All of them have some stuff that I like but up till now all have their own downsides. I wonder what helix aims to achieves.

Also, since the project is new, we have the luxury to change the keymaps at the start, having used quite a few editors I think some of the keys in kakoune could be improved (some not easy to remember and some useless, like x vs X). Maybe we could create an RFC and discuss the alternatives and which keys to do what? By the way, I like kakoune alt, but not the limitation of terminal not being able to differentiate between ctrl-shift and ctrl, alt is similar case IIRC.

Panic when trying to create newline after text - (osx)

Just installed helix from source and was playing around by entering some text and immediately panics after hitting enter:

package main

thread 'main' panicked at 'Attempt to index past end of Rope: char index 12, Rope char length 12',

Time machine?

:ear ~1f and :lat 1h in vim IIRC

And also history branching like g+ and g-, not sure if kakoune supports them but I miss them.

Feature: Open file picker by default when the specified path is a directory

I would like to see the contents of a directory when opening hx with a path to directory like:

hx /tmp

Shows me file picker with the contents of /tmp.

I would like to give a try at implementing this.

Panic opening hx

I get this running on Windows. I am running in the clone folder itself.

thread 'main' panicked at 'index out of bounds: the len is 2496 but the index is 2496', helix-tui\src\buffer.rs:185:14
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

Yank to system clipboard

It would be nice if you could yank the current selection to the system clipboard.

Support ctrl-f and ctrl-b to page up/down

First thing I did in helix is ctrl-f and I am surprised it didn't work, pagedown is too far for me to press.

Search stops working when match jumps over an Unicode symbols

When searching using /, going to the next match using n stops working when you've passed the character ⽆.

Environment

• hx v0.0.9
• helix-term 0.1.0

Steps to reproduce

Given the following file:

test:
key
⽆
key
key

1. Put your cursor at the first line test:. Search for key using /key
2. Press n for next match
3. Press n for next match (does not work)

Panic on non-UTF-8 files

For example trying to open the hx binary:

❯ hx target/debug/hx
thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: stream did not contain valid UTF-8', helix-term/src/main.rs:117:46
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

I don't know if there is a plan to support other text encodings but it sure would be nice to just be able to view a raw binary file as a fallback. The current implementation of Document uses Rope internally, from what I've seen it accepts only valid UTF-8 so not really sure how it could be handled here.

Resizing a bunch causes index out of bounds

Issues with `pyls`

Seems like Helix panics when it tries to open Python files specifically, I tried both large and small files, it panicked on both, both when the file is given using the CLI and both when selected through the :open <file.py> option.
I was able to open TOML, Rust, C, C++, txt, XML, CSV, JSON perfectly well.

thread 'main' panicked at 'called `Option::unwrap()` on a `None` value', helix-lsp/src/client.rs:156:18

Reproducible in both helix-git and helix-bin AUR packages.
(Seems like it also panics when I try to extract the version on the helix-git package)

Failed to initialize logging on read-only HOME

I'm on Debian Jessie but the HOME is read-only atm.
So I set CARGO_HOME to a writable location and installed helix from source as specified in the README.
The runtime folder was copied to $CARGO_HOME/bin.
I tested this setup on another machine (OSX) with writable home and it works properly there.
On the Debian however, I get

Error: failed to initialize logging

Caused by:
    Read-only file system (os error 30)

when starting hx.

Resize to larger screen too slow

Terminal kakoune
Helix using latest master 661dbdc

When resizing terminal to a larger terminal size (full size), it takes like 2-3 wall clock seconds, but resizing it to a smaller terminal size doesn't cost much. It's like lagged for a bit.

index out of bounds on Windows

when I run the command hx (v0.0.6 binary from the release page) on Windows 10 it panics immediately with

thread 'main' panicked at 'index out of bounds: the len is 3451 but the index is 3451', helix-tui\src\buffer.rs:185:14

I'm using Windows Terminal, and the len changes depending on the terminal size.

List of mwes that panic

These are minimal working examples of inputs after hx that cause a panic, tested on ubuntu and macOS.

j, b

j, w

j, e

j, f, f

d, f, f

d, f, n

i, a, esc, b, w

i, a, esc, b, e

and someone else brought up d, d.

I tried making the calls to slice.char(_) safe in the varioushelix-core::movement functions, but that caused off by ones in coords_at_pos and something in the compositor, I'm not sure if it's because of bad indexing elsewhere, or if my "fixes" aren't obeying rules about the anchor/head points for Range. Others have also noted that it seems like you can move down one more line than you would be able to in IE kakoune, but that doesn't seem to explain the d, d or b cases.

Just poking around, there seems to be a lot of interaction with ropey via partial functions which may not be ideal in the long run. It's a bummer that ropey doesn't seem to offer total versions of the indexing functions.

Cool project by the way, I wish you the best of luck.

Panic when trying to run heilx on non-existent file

Running hx on a non-existent file (to create it) will panic on osx. File has to be created before hx can open/edit

hx test.go
---
thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: No such file or directory (os error 2)', helix-term/src/main.rs:117:46

File picker does not match all files

In the root of my current project I have a Gemfile. In a sub directory relative to the root I also have a Gemfile. Opening the file picker and searching for Gemfile only result in sub-directory/Gemfile. The root Gemfile isn't matched. In fact, a lot of the root level files aren't matched. Rakefile and Procfile are not matched while Dockerfile and Guardfile are.

In a smaller project, these files are found just fine.

Looks like this might be the culprit

helix/helix-term/src/ui/mod.rs

Lines 88 to 91 in c67e318

	const MAX: usize = 2048;
	Picker::new(
	files.take(MAX).collect(),

If the project is large enough, this might exclude files exceeding MAX. Since the picker isn't updating the set of files upon filtering, some files will always be excluded.

My Rust knowledge is pretty much non-existent, but would it make sense to pass the iterator directly to the picker and let the Picker limit the iterator after matching?

helix/helix-term/src/ui/picker.rs

Lines 79 to 91 in c67e318

	matches.extend(
	self.options
	.iter()
	.enumerate()
	.filter_map(|(index, option)| {
	// TODO: maybe using format_fn isn't the best idea here
	let text = (format_fn)(option);
	// TODO: using fuzzy_indices could give us the char idx for match highlighting
	matcher
	.fuzzy_match(&text, pattern)
	.map(|score| (index, score))
	}),
	);

So if self.options now is the files iterator containing all results, we could limit the results by adding .take(MAX) at the end and end up with something like:

 self.options
    .enumerate()
    .filter_map(|(index, option)| {
        let text = (format_fn)(option);
        matcher.fuzzy_match(&text, pattern).map(|score| (index, score))
    })
    .take(MAX),

Is there any tutorial materials on how to write extension for Helix?

This work seems very elegant :) For daily usage it would be better to create some customary key-bindings and some scripts to invoke command line applications. I am wondering that if there is some contents describe the way to do so. Rust is indeed a good language, hope they can compose well

Panic in command prompt: Trying to access position outside the buffer

1. start helix with cargo run
2. press :q

I am on arch linux, using xterm. This looks like off-by-one error handling terminal screen size.

panics when deleting from empty buffer

I just installed helix using cargo. Running hx and then immediately typing dd causes:

thread 'main' panicked at 'Attempt to slice past end of RopeSlice: slice end 1, RopeSlice length 0'

The first input of d also causes the line number 1 to disappear.

When file picker is open and window is resized the main thread panics

As the title says, when the file picker window is open and I split the terminal window verticaly using tmux there is a panic:

thread 'main' panicked at 'index out of bounds: the len is 3780 but the index is 3780', helix-tui/src/buffer.rs:185:14

When I first split the window and then open the file picker it correctly scales later on when the split is closed and opened again.

External command support

Will there be any external command support? I think that would provide a way to do what internal command missing on early stage, like grep, git etc.

Panic with 'J' on a single line file.

thread 'main' panicked at 'Attempt to index past end of slice: line index 1, slice line length 1', C:\Users\runneradmin\.cargo\registry\src\github.com-1ecc6299db9ec823\ropey-1.2.0\src\slice.rs:534:9

homebrew tap private?

brew tap helix-editor/helix expects the homebrew tap to resolve to https://github.com/helix-editor/homebrew-helix, but I cannot see that repository.

Open folders cause errors

I would like to navigate the directory, sort of like NERDTree in vim.

Is this possible?
Also is it possible to open folder?

I run:

❯ ~/Downloads/helix-v0.0.7-x86_64-linux/hx .

To open the current folder and its files. But i get:

❯ ~/Downloads/helix-v0.0.7-x86_64-linux/hx .
Error: unable to create new appliction

Caused by:
    Is a directory (os error 21)

Add documentation on adding the runtime variable for specific languages (go, Typescript, Rust)

Hello!
I love the project! ❤️

However I cannot seem to get my head around setting the runtime variable to get syntax highllighting and stuffz for my Go projects or Typescript/Javascript or Rust projects.

I move the hx binary into the different projects, however it does not seem to pickup the runtime.
Could you provide a example for let's say a Go project using go.mod and explicitly setting the HELIX_RUNTIME variable for that?

Gui

I noticed that your website references creating a gui with skia/skulpin. That sounds very similar to my architecture for neovide which is a gui for neovim.

A not broadly stated goal for neovide is to eventually expose the graphical parts as a swappable front end for other text editors such as what helix looks like. I was curious if you are interested in such a collaboration. Getting a gui right is hard work (as I've found out), I think collaborating would be great for both use cases!

Are you planning on exposing a gui protocol ala neovim's? If so what would that look like/what features do you think would be useful for helix that are unique to helix? The editor looks very cool btw!

PAnics when adding a new line, no syntax highlighting for rust

Arrow key mappings

In both Kakoune and Vim arrow keys are usually mapped to moving the cursor.

I understand this might be a design choice.

A non-elegant implementation: github.com/itzmjauz/helix
