Add :earlier and :later commands that can be used to navigate the full edit history. (#194)
* Disable deleting from an empty buffer which can cause a crash.

* Improve on the fix for deleting from the end of the buffer.

* Clean up leftover log.

* Avoid theoretical underflow.

* Implement :before which accepts a time interval and moves the editor to
the closest history state to the commit of the current time minus that
interval. Current time is now by default, or the commit time if :before
has just been used.

* Add :earlier an :later commands that can move through
the edit history and retrieve changes hidded by undoing
and commiting new changes. The commands accept a number
of steps or a time period relative to the currrent change.

* Fix clippy lint error.

* Remove the dependency on parse_duration, add a custom parser instead.

* Fix clippy errors.

* Make helix_core::history a public module.

* Use the helper for getting the current document and view.

* Handled some PR comments.

* Fix the logic in :later n.

* Add an alias for :earlier.

* Add an alias for later.

* Run cargo fmt.

* Add some tests for earlier and later.

* Add more tests and restore the fix for later that diappeared somehow.

* Use ? instead of a match on an option.

* Rename to UndoKind.

* Remove the leftover match.

* Handle a bunch of review comments.

* More systemd.time compliant time units and additional description for the new commands.

* A more concise rewrite of the time span parser using ideas from PR discussion.

* Replace a match with map_err().

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

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.

Installation

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

We provide packaging for various distributions, but here's a quick method to build from source.

git clone --recurse-submodules --shallow-submodules -j8 https://github.com/helix-editor/helix
cd helix
cargo install --path helix-term

This will install the hx binary to $HOME/.cargo/bin.

Now copy the runtime/ directory somewhere. Helix will by default look for the runtime inside the same folder as the executable, but that can be overriden via the HELIX_RUNTIME environment variable.

NOTE: You should set this to /runtime in development (if running via cargo).

export HELIX_RUNTIME=$PWD/runtime

If you want to embed the runtime/ directory into the Helix binary you can build it with:

cargo install --path helix-term --features "embed_runtime"

Arch Linux

There are two packages available from AUR:

  • helix-bin: contains prebuilt binary from GitHub releases
  • helix-git: builds the master branch of this repository

MacOS

Helix can be installed on MacOS through homebrew via:

brew tap helix-editor/helix
brew install helix

Contributing

Contributors are very welcome! No contribution is too small and all contributions are valued.

Some suggestions to get started:

  • You can look at the good first issue label on the issue tracker.
  • Help with packaging on various distributions needed!
  • To use print debugging to the ~/.cache/helix/helix.log file, you must:
    • Print using log::info!, warn!, or error!. (log::info!("helix!"))
    • Pass the appropriate verbosity level option for the desired log level. (hx -v <file> for info, more vs for higher severity inclusive)
  • If your preferred language is missing, integrating a tree-sitter grammar for it and defining syntax highlight queries for it is straight forward and doesn't require much knowledge of the internals.

We provide an architecture.md that should give you a good overview of the internals.
