A performant and extensive terminal-based project editor with a wide variety of modern shortcuts.

How to use

omega [path]

This section will guide you through the initial steps of opening the editor. When specifying a path, if it points to a file, the editor will set the surrounding directory as the project directory. If the path points directly to a directory, that directory will become the project directory.

Within the editor, you'll find a panel on the left side that displays your project's directory structure, allowing for easy navigation through your project files.

Navigating through your project is straightforward: selecting an entry from the left panel will close the currently open file and open the newly selected one. The editor efficiently manages your files by checking if a file is already open and retrieving its data from its current state or loading it from the filesystem to store in the state. All changes to files are temporarily cached in the state using a Hashmap, ensuring that unsaved files can be reopened, edited further, and eventually saved, provided the editor remains open. Upon exiting the editor (using Ctrl + q), it will prompt you to save any unsaved changes.

Files that are being edited will be marked with an asterisk * in the title bar; saving these files will remove the asterisk.

The editor also offers Global Keybindings for file and directory management tasks, such as adding, editing, and deleting. Please exercise caution when deleting files, as this action is irreversible, with no intermediate trash bin for recovery.

Installation

To install omega, you can use Cargo by running the following command in your terminal:

cargo install omega

Alternatively, you can download the binary directly from the releases page.

Additional Requirements

For Linux-based systems, it is necessary to have the libx11-dev (Debian/Ubuntu) or libX11-devel (Fedora/RHEL) packages installed.

It's important to note that on Unix-based systems, omega relies on ncurses as its backend, which will need to be installed. For Windows users, omega uses crossterm as its backend.

    (⚠Unstable⚠) syntec syntax highlighting

    I have tried to implement syntax highlighting by using syntec and modifying the draw() function from the EditArea. My attempt is extremely buggy (it crashes sometime at random when using the editor) so i recommend to improve my code when mergin or putting it into another branch.

    Known Errors/Bugs

    • ~~(sometimes) crash when resizing the terminal~~
    • (sometimes) crash when deleting content at the top/end of the file
    • ~~(always) crash when there isn't enough space for the code~~
    • ~~(always) crash when "cursive ui" doesn't fit in the terminal window~~
    • ~~(sometimes) crash when opening a file~~

    After trying to compile on void I get this error about the clippers dependency:

    error: could not find native static library `z`, perhaps an -L flag is missing?

    I have zlib-devel and libX11-devel installed so I'm not sure what else I need.
