Grab is a tool that downloads source code repositories into a convenient directory layout created from the repo's URL's domain and path. It supports Git, Mercurial (hg), Subversion, and Bazaar repositories.

$ grab github.com/jmhodges/grab # https://github.com/jmhodges/grab also works.

$ ls ~/src/github.com/jmhodges/grab
LICENSE   README.md go.mod    go.sum    grab      main.go

By default, grab downloads into $HOME/src (overridable with the env var GRAB_HOME). The repo github.com/jmhodges/grab was stored in it with the domain (github.com) as the top-level directory, and jmhodges and grab created as subdirectories down the path.

Also, the input to grab doesn't have to contain a scheme (e.g. https://) to work.

Grab can be installed by running go install github.com/jmhodges/grab.
