The simple but flexible text editor

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...

1. 🪶 Is lightweight and efficient
2. 🔧 Can be configured to your heart's content
3. 📦 Has useful features out of the box

...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 works best on linux, but macOS and Windows are also supported.

• 🪶 Ox is lightweight, with the precompiled binary taking up a few megabytes 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.

• 🔌 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

• 🖌️ 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
• ⚔️ Multi-editing features such as multiple cursors and recordable macros
• 🪟 Splits to view multiple documents on the same screen at the same time

• 🌐 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
• 🌈 Automatically adapts your colour schemes to work on terminals with limited colours

To get started, please click on your operating system

• 🐧 Linux
• 🪟 Windows
• 🍎 MacOS

Here are the list of available methods for installing on Linux:

• Manually
• Binary
• Arch Linux
• Fedora
• Debian / Ubuntu

Install one of the following from the AUR:

• ox-bin - install the pre-compiled binary (fastest)
• ox-git - compile from source (best)

You can find an RPM in the releases page

Install using the following command:

sudo dnf install /path/to/rpm/file

You can find a deb file in the releases page

Install using the following command:

sudo dpkg -i /path/to/deb/file

Here are the list of available methods for installing on Windows:

• Manually (best)
• Binary

Here are the list of available methods for installing on macOS:

• Manually
• Binary
• Homebrew
• MacPorts

Install ox from Homebrew core tap.

brew install ox

On macOS, you can install ox via MacPorts

sudo port selfupdate
sudo port install ox

There are precompiled binaries available for all platforms in the releases page.

• For Linux: download the ox executable and copy it to /usr/bin/ox, then run sudo chmod +x /usr/bin/ox
• For MacOS: download the ox-macos executable and copy it to /usr/local/bin/ox, then run sudo chmod +x /usr/local/bin/ox
• For Windows: download the ox.exe executable and copy it into a location in PATH see this guide for how to do it

This is the absolute best way to install Ox, it will ensure you always have the latest version and everything works for your system.

You must have a working installation of the Rust compiler to use this method. Visit the website for rustup and follow the instructions there for your operating system.

Now with a working version of rust, you can run the command:

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

This will take at worst around 2 minutes. On some more modern systems, it will take around 30 seconds.

Please note that you should add .cargo/bin to your path, which is where the ox executable will live, although rustup will likely do that for you, so no need to worry too much.

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.

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

ox

This will open up an empty document.

However, if you've just downloaded Ox, the configuration assistant will automatically start up and help you configure the editor initially.

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.

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.

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

By default, you will be greeted by a configuration assistant when first starting Ox, when no configuration file is in place. This will help you generate a configuration file.

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'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 6 different stages:

1. Installation - advice and how-tos on installation
2. Configuring - changing the layout, adding to and changing the syntax highlighting
3. General Editing - editing a document and controlling the editor
4. Command Line - using the command line interface
5. Plugins - installing or uninstalling community plug-ins and writing or distributing your own plug-ins
6. Roadmap - planned features

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