Say no to tabs and yes to panes when developing
For today’s post in the Code Challenge series, I’m giving an intro on tmux. As a Developer Evangelist, showing code is the best way to get developers interested in how easy it is to integrate the SendGrid API. When you’re up in front of a couple of hundred devs and live coding, switching through multiple tabs is not a good look. I got into tmux because it lets you open multiple programs on the same window to see everything that’s happening.
Tmux has since become part of my workflow whenever coding any new python application. I can’t get away from Xcode when developing for iOS just yet.
Here is how a typical tmux session looks for me:
Get it now and follow along below!
brew install tmux
sudo add-apt-repository ppa:pi-rho/dev sudo apt-get update sudo apt-get install tmux
Commands I’ve found helpful
Tmux has a default binding set to ctrl-b, so for example if you want to split the screen with two sessions just type ctrl-b and %, in the future I will just type (ctrl-b + %).
(ctrl-b + "): splits the window horizontally (ctrl-b + arrow key): switches the active pane
(ctrl-b + [): puts the pane in scroll mode so you can scroll up and down with your arrow keys.
These are useful to have for working on different applications that require different environments. I have a session called “Demo” which I use when doing live demos to developers. I have another session which I use for development.
tmux new -s session-name
Creates a new tmux session with the name you gave it.
Lists available sessions.
(ctrl-b + d)
Detaches the session being currently used.
tmux attach -t session-name
Attaches to the session.
This post really just skims on what you can do with tmux.

Check back into the SendGrid Blog every Monday, Wednesday, and Friday for the next few weeks to see what I’m working on! You can also visit my intro post that will have an updated list of everything I’ve written for my 15 Days of Code Challenge.
