docker-emacs

My Emacs and ZSH; Dockerized

I use the following script day-to-day to launch emacs with `e`. Note that since I use git mainly, the script has different behavior for when it is executed in git repos.

e () {
    if [ $(git rev-parse --is-inside-work-tree 2>/dev/null) ]
    then
        if [[ -n $1 && ( -a $1 || -d $1 ) ]]
        then
            FULLPATH=$1:A
            GITPATH=$(git rev-parse --show-toplevel)
            GIT_PATH_LENGTH=${#GITPATH}
            EDIT_FILE_PATH=$FULLPATH[$GIT_PATH_LENGTH+2,${#FULLPATH}]
            docker run -itv $(git rev-parse --show-toplevel):/files --rm biscarch/emacs emacs /files/$EDIT_FILE_PATH
        elif [[ -n $1 && ! -a $1 && ! -d $1 ]]
        then
            echo "Does not support creation of new files. Please touch first."
        else
            docker run -itv $(git rev-parse --show-toplevel):/files --rm biscarch/emacs emacs /files
        fi
    else
        if [[ -n $1 && ( -a $1 || -d $1 ) ]]
        then
            FULLPATH=$1:A
            THEPATH=`pwd`
            EDIT_FILE_PATH=$FULLPATH[${#THEPATH}+2,${#FULLPATH}]
            docker run -itv $THEPATH:/files --rm biscarch/emacs emacs /files/$EDIT_FILE_PATH
        elif [[ -n $1 && ! -a $1 && ! -d $1 ]]
        then
            RELATIVEPATH=$1
            THEPATH=`pwd`
            touch $RELATIVEPATH
            docker run -itv `pwd`:/files --rm biscarch/emacs emacs /files/$RELATIVEPATH
        else
            docker run -itv `pwd`:/files --rm biscarch/emacs emacs /files
