Ret

Ret is a tool that goes up the directory chain and returns the first directory with a landmark.

A landmark is an important property of the directory, such as the existence of a configuration file, being the user’s home directory, or being on a different drive.

How to use

You can use this to go back to your project root in a jiffy by using your shell’s command substitution syntax, e.g.:

cd $(ret)

or

cd (ret)

You can specify a set of landmark names as the arguments to ret to only use them. You can also specify a set of default landmark names in $XDG_CONFIG_HOME/ret/landmarks.txt, one per line.

You are invited to contribute more landmark specifications! Look in the source code, it’s easy.

Shell integration

After installing (see below), you can make using ret even more convenient by defining a shell function that does cd for you.

e.g.

ret() {
  cd $(command ret "$@")
}

or

function ret
  cd (command ret $argv)
end
