sued - shut up editor

sued is a stateless vector-oriented command-based text editor written in Rust, with focus on speed, simplicity, ease of use and staying the hell out of your way. It's inspired by more contemporary editors, such as the ed family (ed, em, ex, vi, Vim, Neovim, etc.).

No, it's not "super user editor", or an editor that will sue you. It's "soo-ed", "shut up editor".

To be clear, it's a text editor that works on Rust's Vec type. To be clearer, it's a text editor that works on lines and isn't graphical, like you're probably used to.

Yes, I know ed doesn't use vectors, shut up

Written in Rust, because frick you, that's why.

Obtaining

First of all, you need Cargo. If you don't have Cargo, install Rust. If you don't want to install Rust, frick off and use a different editor.

Run

cargo install sued

and make sure that ~/.cargo/bin/ is in your PATH or you won't be able to run it.

Documentation

sued's documentation is present online in the form of a man page-like website.

You can also just read the source code yourself.

Accelerated

sued is written in pure, idiomatic Rust.

Its speed, as a compiled line editor, is pretty damn fast. The time between opening it up and getting some text edited is negligently small.

You can even run a compiler or an interpreter with a simple ~runhere, without even the need to save your file.

And it doesn't even take a second. As it should be.

Uncomplicated

sued is much more user-friendly than ed - it's a modeless editor, so there's no complicated mode switching to keep in your head. You're always in insert mode.

It also uses a simple command syntax, with whole words, like ~save, ~show and ~open, not single letters.

Its error messages, despite being communicated concisely, are still informative and use colloquial language, so they're pretty easy to understand.

Efficient

sued looks basic on the offset, but under the hood, it has support for regex replacements, file searching, pretty-looking line numbers, and some other stuff.

sued's command set consists of stuff like delete, indent, insert, open, run, runhere, save, search, show, substitute, swap, and so on.

For the rest of the commands, as well as information on what these commands do, run ~help inside sued or check out the documentation.

And sued leverages linefeed for its command line input. Meaning it supports GNU Readline commands and functionality. You can do some Emacs-style line navigation, like C-a, C-e, C-f, C-b, whatever you want, it'll work. Probably.

Integrated

Most text editors will boast stuff like VCS, LSP, debug tool, compiler, interpreter and linter integration. sued, however, is not one of those.

Instead of integrating itself with anything, sued provides the ~run and ~runhere commands to run a shell command as if you ran it in your terminal, without ever having to leave sued, and when the command is done, you're immediately back to editing.

And ~runhere is special - it will have sued create a temporary file and run the chosen command with that temporary file as an argument, and then when that external program is done operating on the temporary file, it's read and synchronised with the original buffer contents.

Writing a Python script? ~runhere python. Want to check your Markdown file is up to scratch? ~runhere markdownlint. Need to hop to a more powerful editor whenever you need that power? ~runhere vim. It's that simple.

No-nonsense

sued is designed to not get in your way. Error messages are useful but brief.

They're not ed levels of brief, but they're still pretty brief.

And there's no auto-save feature - your file is only saved when you enter the ~save command.

Ubiquitous

Being a CLI app, you can run sued anywhere!

In your terminal, in VS Code, in Emacs, even inside Vim! And sued doesn't care what OS it runs under. Windows, macOS, GNU/Linux, BusyBox/Linux, other kinds of Linux, BSD, ChromeOS, Android, probably Xbox if you really wanted.

If it has a terminal, it can run sued.

It's been tested on Windows, Fedora and Android, and works great under all three.

Free/Libre

sued is free. You can get it for free, but it's also free.

It's released under the GNU General Public License version 3 or later, because free software, hell yeah!
