tmuxr is an R package that allows you to manage tmux and interact with the processes it runs. It features a pipeable API with which you can create, control, and capture tmux sessions, windows, and panes.


The recording below demonstrates various capabilities of tmuxr such as: running processes, sending keys, splitting windows, and capturing panes. Note that normally, managing tmux and the processes it runs is done in a detached mode, so you wouldn’t see anything, but the result would be the same.

tmuxr is available through CRAN and can be installed with install.packages("tmuxr"). The development version can be installed from this repository using remotes:

# install.packages("remotes")


We regularly test tmuxr on Ubuntu with tmux versions 2.1 through 3.1c and on macOS with the latest version of tmux provided by Homebrew. tmuxr might work on Windows using Cygwin or WSL, but we haven’t tested this.
