I love entr! It's been part of literally every development environment I setup since I discovered it. Re tmux: I have a function in my fish config (used to be zsh) that runs when I changed directories; if there is a `.tmux` script in the new directory, the function looks for a tmux session by the name of the directory, attaching if it exists, and, if it does not, creating a new session by running `.tmux`, which creates a handful of windows with my file watchers, build runners, container managers, etc etc. So all I have to do to boot up a project environment is move into the src directory, and poof — all the scripts that build source, run containers, and restart things on various config file changes get booted up immediately.
