Set up tmux for pair programming in a remote environment
Pair programming is a technique where two developers work together on the same task.
One is the "driver", typing and interacting with the code, while the other is the "navigator",
reviewing the code and suggesting improvements.
This method can significantly improve code quality and encourage learning.
When working remotely, keeping both developers on the same page can be challenging.
However, tmux - a terminal multiplexer - makes this easier by allowing
multiple users to share a session, even across different locations.
I'll explore how to set up tmux for pair programming, which involves two steps:
- Both users accessing the same server or system
- The server setup (for the driver) and the client setup (for the navigator)
Server setup
First, the "driver" needs to set up the tmux session.
This requires access to a shared system or server where both developers can connect.
On the server, run the following commands:
bash
tmux -2 -S /tmp/pair new-session -s PairProgramming
chmod 777 /tmp/pair
This command creates a new tmux session called PairProgramming
but you can call it whatever you'd like.
Client setup
On the client (the "navigator"), run this command to attach to the tmux session:
bashtmux -2 -S /tmp/pair attach-session -t PairProgramming
The navigator will now be able to see the same terminal session as the driver.
Both users can interact with the session in real-time.
Alternatives to consider
If you're working in different environments or need more advanced features
(like a graphical interface or more robust collaborative tools), consider using other solutions
such as
VS Code's Live Share
feature or cloud-based IDEs.
