add reflow command (#2128)
* add reflow command

Users need to be able to hard-wrap text for many applications, including
comments in code, git commit messages, plaintext documentation, etc. It
often falls to the user to manually insert line breaks where appropriate
in order to hard-wrap text.

This commit introduces the "reflow" command (both in the TUI and core
library) to automatically hard-wrap selected text to a given number of
characters (defined by Unicode "extended grapheme clusters"). It handles
lines with a repeated prefix, such as comments ("//") and indentation.

* reflow: consider newlines to be word separators

* replace custom reflow impl with textwrap crate

* Sync reflow command docs with book

* reflow: add default max_line_len language setting

Helix

Build status

Screenshot

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.

Installation

Packages are available for various distributions (see Installation docs).

If you would like to build from source:

git clone https://github.com/helix-editor/helix
cd helix
cargo install --path helix-term
hx --grammar fetch
hx --grammar build

This will install the hx binary to $HOME/.cargo/bin and build tree-sitter grammars.

Helix also needs its runtime files so make sure to copy/symlink the runtime/ directory into the config directory (for example ~/.config/helix/runtime on Linux/macOS, or %AppData%/helix/runtime on Windows).

OS command
windows xcopy runtime %AppData%/helix/runtime
linux/macos ln -s $PWD/runtime ~/.config/helix/runtime

This location can be overridden via the HELIX_RUNTIME environment variable.

Packages already solve this for you by wrapping the hx binary with a wrapper that sets the variable to the install dir.

NOTE: running via cargo also doesn't require setting explicit HELIX_RUNTIME path, it will automatically detect the runtime directory in the project root.

In order to use LSP features like auto-complete, you will need to install the appropriate Language Server for a language.

Packaging status

MacOS

Helix can be installed on MacOS through homebrew via:

brew tap helix-editor/helix
brew install helix
