Readme for up-1.0.0.4

[back to package description]

Homepage: https://github.com/thomaseding/up

Hackage: https://hackage.haskell.org/package/up

Install from git repository:

$ cabal configure
$ cabal build
$ cabal install

Install from Hackage.

$ cabal update
$ cabal install up

These will install the up command.

Example usage:

$ cd /home/thomas/code/up/src
$ up thomas
../../..
$ up --absolute thomas
/home/thomas
$ up ....
../../..
$ up --relative --from-to /abc/def/xyz/ abc
../../..

See up --help for more info.

up generates file path strings, but it (by itself) does not change your current working directory. So below is code you can add to your shell's config file (e.g. .bashrc) to use the up program to change your directory.

g () {
    local DEST
    DEST=$(up "$@")
    if [ "$?" == '0' ]
    then
        cd "$DEST"
    else
        return "$?"
    fi
}

Example usage:

$ cd /home/thomas/code/up/src
$ g thomas
$ pwd
/home/thomas

For shell autocomplete for the above g command, you can add this to your shell's config in addition:

_g () {
    if [ "$COMP_CWORD" == "1" ]
    then
        local cur=${COMP_WORDS[COMP_CWORD]}
        local parts="$(pwd | tr '/' ' ')"
        COMPREPLY=( $(compgen -W "$parts" -- $cur) )
    fi
}
complete -F _g g
