Print the root directory of the current working copy of a version controlled repository.

wcroot

Invoking wcroot will determine whether the current directory is inside a working copy of a version controlled repository and print the full path to the root of the working copy to stdout. If no working copy is found then wcroot simply does nothing.

Currently supported working copy formats:

• Git
• Mercurial
• Subversion

Example usage

Normal usage:

[user@host ~/dev/root/subdirectory]$ wcroot
/home/user/dev/root
[user@host ~/dev/root/subdirectory]$

Path as a parameter:

[user@host ~]$ wcroot ~/dev/root/subdirectory
/home/user/dev/root
[user@host ~]$

Outside of a working copy:

[user@host ~/not/a/working/copy]$ wcroot
[user@host ~/not/a/working/copy]$

In a script:

# `cd` with no arguments will first attempt to change to the root of
#  the current working copy.  If already at the root or no working
#  copy is found, cd to $HOME.
function cd() {
    root=$(wcroot)
    if [ $# -ne 0 ]; then
        builtin cd "$1"
    elif [ -n "$root" -a "$PWD" != "$root" ]; then
        builtin cd "$root"
    else
        builtin cd
    fi
}
