Wye is reverse tee.

What is wye?

Wye is a simple terminal tool that works like a reverse tee. Instead of splitting one input into multiple outputs, wye combines multiple inputs into one terminal session. It reads commands from your keyboard and also from a special file called a named pipe.

It gives you terminal sessions like tmux, but in a much simpler way without a background server.

Wye use wye?

The main goal of wye is to work together with programs like tmux. It gives you a simple way to send commands and text to a terminal session from a different window or from a script.

How to Use

Start a new session

To start a new session with your default shell, just run:

wye

Run a specific program

To run a different program inside the session, pass it as an argument:

wye lua

Use a specific session number

This creates a session with a number that you can easily find later.

wye -s123

Check your current session

If you are already inside a wye session, running wye again will not start a new one. It will just show you the current session number.

How It Works

Wye manages sessions using special files called named pipes. Each session has its own pipe file located in /tmp/wye-<session_number>.

To send a command to a running session, you just need to write to its pipe file. For example, to send the ls -l command to session 123, you can run this from another terminal:

echo "ls -l" > /tmp/wye-123

The command will appear in the wye session as if you typed it.

Building from Source

cargo build --release

The final program will be located at target/release/wye.

Installing from Source
