Customizable/configurable status line (#2434)
* feat(statusline): add the file type (language id) to the status line

* refactor(statusline): move the statusline implementation into an own struct

* refactor(statusline): split the statusline implementation into different functions

* refactor(statusline): Append elements using a consistent API

This is a preparation for the configurability which is about to be
implemented.

* refactor(statusline): implement render_diagnostics()

This avoid cluttering the render() function and will simplify
configurability.

* feat(statusline): make the status line configurable

* refactor(statusline): make clippy happy

* refactor(statusline): avoid intermediate StatusLineObject

Use a more functional approach to obtain render functions and write to
the buffers, and avoid an intermediate StatusLineElement object.

* fix(statusline): avoid rendering the left elements twice

* refactor(statusline): make clippy happy again

* refactor(statusline): rename `buffer` into `parts`

* refactor(statusline): ensure the match is exhaustive

* fix(statusline): avoid an overflow when calculating the maximal center width

* chore(statusline): Describe the statusline configurability in the book

* chore(statusline): Correct and add documentation

* refactor(statusline): refactor some code following the code review

Avoid very small helper functions for the diagnositcs and inline them
instead.
Rename the config field `status_line` to `statusline` to remain
consistent with `bufferline`.

* chore(statusline): adjust documentation following the config field refactoring

* revert(statusline): revert regression introduced by c0a1870

* chore(statusline): slight adjustment in the configuration documentation

* feat(statusline): integrate changes from #2676 after rebasing

* refactor(statusline): remove the StatusLine struct

Because none of the functions need `Self` and all of them are in an own
file, there is no explicit need for the struct.

* fix(statusline): restore the configurability of color modes

The configuration was ignored after reintegrating the changes of #2676
in 8d28f95.

* fix(statusline): remove the spinner padding

* refactor(statusline): remove unnecessary format!()

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

This will install the hx binary to $HOME/.cargo/bin and build tree-sitter grammars. If you want to customize your languages.toml config, tree-sitter grammars may be manually fetched and built with hx --grammar fetch and hx --grammar build.

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(cmd.exe) xcopy runtime %AppData%/helix/runtime
windows(powershell) xcopy runtime $Env: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
