Ox editor

Ox is a code editor that runs in your terminal.

About

Ox is an independent text editor that can be used to write everything from text to code.

If you're looking for a text editor that...

🪶 Is lightweight and efficient
🔧 Can be configured to your heart's content
📦 Has features out of the box, including
- syntax highlighting
- undo and redo
- search and replace
- line numbers
- opening multiple files
- full mouse cursor interaction

...then Ox is right up your street

It runs in your terminal as a text-user-interface, just like vim, nano and micro, however, it is not based on any existing editors and has been built from the ground up.

It is mainly used on linux systems, but macOS and Windows users (via WSL) are free to give it a go.

Selling Points

Lightweight and Efficient

🪶 Ox is lightweight, with the precompiled binary taking up roughly 4mb in storage space.
🪢 It uses a rope data structure which allows incremental editing, file reading and file writing, which will speed up performance, particularly on huge files.
🦀 It was built in Rust, which is a quick lower level language that has a strong reputation in the performance department.

Strong configurability

🔌 Plug-In system where you can write your own plug-ins or integrate other people's
🔧 A wide number of options for configuration with everything from colours to the status line to syntax highlighting being open to customisation
🌔 Ox uses Lua as a configuration language for familiarity when scripting and configuring
🤝 A configuration assistant to quickly get Ox set up for you from the get-go

Out of the box features

🖌️ Syntax highlighting
↪️ Undo and redo
🔍 Search and replace text
📁 Opening multiple files at once
👁️ UI that shows you the state of the editor and file
🖱️ You can move the cursor and select text with your mouse
✍️ Convenient shortcuts when writing code

Robustness

🌐 Handles double-width unicode characters like a charm, including those of the Chinese, Korean and Japanese languages and emojis
🥊 Backend has been thoroughly tested via automated unit tests

Installation

⚠️ Huge Warning: A lot of these (except manual, AUR and homebrew) are quite out of date, it is quite a huge task having to push to all these sources each time I update and I'd rather focus on creating high-quality updates

Prerequisites

Because Ox is written in Rust, you must have a modern and working version of rustc and cargo.

On Arch Linux, you can run this command:

sudo pacman -S rustup
rustup toolchain install stable

If you are not using Arch, you can easily set it up on other distros by running the distro-neutral command:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
/usr/bin/rustup toolchain install stable

You must have curl installed to run this command.

Installation Routes

It should only really take at most 1 minute on most modern hardware.

cargo install --git https://github.com/curlpipe/ox ox

Arch Linux

Install ox-bin or ox-git from the Arch User Repository.

That's all there is to it!

Fedora/CentOS

Install ox from the COPR Repository:

sudo dnf copr enable atim/ox -y
sudo dnf install ox

You can also find an RPM file in the releases page

Debian

You can find a deb file on the releases page, which can be installed via dpkg:

dpkg -i ox_version.deb

Homebrew

Install ox from Homebrew core tap.

brew install ox

MacPorts

On macOS, you can install ox via MacPorts

sudo port selfupdate

Quick Start Guide

This is just a quick guide to help get you up to speed quickly with how to use the editor. You dive into more details in the documentation section below, but this quick start guide is a good place to start.

Opening Files

At the moment, you can open ox by using the command

ox

This will open up an empty document.

If you wish to open a file straight from the command line, you can run

ox /path/to/file

To open and edit a file. You can provide multiple arguments of files if you wish to open more than one, for example:

ox file1.txt file2.txt

You can also open a file from within Ox by using the Ctrl + O key binding

If at any time, you wish to create a new file, you can use Ctrl + N to do so.

You can find more command line options for Ox by typing:

ox --help

When you open multiple files, notice the tabs at the top.

You can close the file you're looking at using the Ctrl + Q key binding. When no more documents are open, the editor will automatically close for you.

If you want to move tabs and look at other files that are open, you can use Shift + Left and Shift + Right to move back and forth respectively.

Editing Files

There are no modes in Ox, so you can just type straight into an open file, just as you would Nano, or Windows notepad.

You can move the cursor around the file using the standard arrow keys.

You can also use:

PageUp - Move up a page in the viewport
PageDown - Move down a page in the viewport
Home - Go to the start of the current line
End - Go to the end of the current line
Ctrl + Left - Go to the previous word
Ctrl + Right - Go to the next word
Ctrl + Up - Go to the top of the document
Ctrl + Down - Go to the bottom of the document

No surprises here, to insert characters, use the letters and numbers on your keyboard. Enter will put a new line in, Tab will create a tab (or indent) and Backspace / Delete to delete characters.

If you modify a file, you may notice a [+] symbol, this means the file has been modified without saving. You can save a document in many ways, including Ctrl + S to save it to the file it was opened from. Ctrl + A to save all files that are open and Alt + S to save as, where a prompt for a new file name to write to will be shown.

We've covered most keyboard shortcuts, but there are some other features you might want to make use of, the following table shows the keyboard shortcuts we haven't covered yet.

Keybinding	What it does
`Ctrl + F`	Searches the document for a search query. Allows pressing of `←` to move the cursor to the previous occurrence of the query and `→` to move to the next occurrence of the query. Press `Return` or `Esc` to leave the search. Note: you can use regular expressions for search queries.
`Ctrl + Z`	Undoes your last action. The changes are committed to the undo stack every time you press the space bar, create / destroy a new line and when there is no activity after a certain period of time which can be used to capture points where you pause for thought or grab a coffee etc...
`Ctrl + Y`	Redoes your last action. The changes are committed to the undo stack every time you press the space bar, create / destroy a new line and when there is no activity after a certain period of time which can be used to capture points where you pause for thought or grab a coffee etc...
`Ctrl + R`	Allows replacing of occurrences in the document. Uses the same keybindings as the search feature: `←` to move the cursor to the previous occurrence of the query and `→` to move to the next occurrence of the query. You can also press `Return` to carry out the replace action. To exit replace mode once you're finished, you can press `Esc`. You can also use `Tab` to replace every instance in the document at once. Note: you can use regular expressions for search queries.
`Ctrl + K`	Opens the command line.
`Ctrl + W`	Shortcut to delete a whole word.
`Alt + Up`	Move the current line up.
`Alt + Down`	Move the current line down.
`Ctrl + D`	Delete the current line.
`Ctrl + C`	Copy selected text.
`Alt + Left`	Move to the previous tab.
`Alt + Right`	Move to the next tab.

Configuration

Ox features a configuration system that allows the editor to be modified and personalised.

By default, Ox will look for a file here: $XDG_CONFIG_HOME/.oxrc or ~/.oxrc.

On Windows, Ox will try to look here C:/Users/user/ox/.oxrc (where user is the user name of your account)

Ox's configuration language is Lua.

For reference, there is a default config in the config folder in the repository. You can either download it and place it in the default config directory or create your own using the example ones as a reference.

If you don't have a config file or don't want to mess around with it, don't worry, Ox has default settings it will use.

Documentation

If you've been through the quick start guide above, but are looking for more detail, you can find in-depth documentation on the wiki page

This will take you step-by-step in great detail through 5 different stages:

Installation - advice and how-tos on installation
Starting - using the command line interface
Using - editing a document and controlling the editor
Configuring - writing plug-ins, changing the layout, adding to and changing the syntax highlighting
Plugins - installing or uninstalling community plug-ins and writing or distributing your own plug-ins
Roadmap - planned features

Hopefully, it contains everything you need to take you from a beginner to a power user.
