Create a log entry for my daily work log, a bit like workingon.co used to work. Commits changes to git

.zshrc

# log what I'm working on to a text file unde `$repo/<year>/<month>/<day>.md`                                             
# change the $repo variable to point to a dir on your machine
# if the dir is a git repo then it will also commit to git, otherwise just do nothing
#
# USAGE: on "working on creating a script to make things better"
function on(){
    local version="1.1.4"
    local repo="/home/jujhar/proj/jujhar-daily-log"
    local year=$(date +%Y) 
    local month=$(date +%m) 
    local day=$(date +%d) 
    local now=$(date "+%Y-%m-%d %H:%M:%S") 
    if [[ -z ${1} ]]; then 
        >&2 echo "You didn't supply anything to log"
        return false
    fi   
    
    # grab text, non need for quotes as we'll munge the param array
    shift $((OPTIND-1))
    local text="$@"
    mkdir -p "${repo}/${year}/${month}"
    echo -e "${now} -- ${text} \n" | \
       tee -a "${repo}/${year}/${month}/${day}.md"

    # if it's a git repo then commit it
    output=$(
    cd "${repo}"
    if git -C . rev-parse;  then 
        echo "commiting repo"
        git pull 
        git add .
        git commit -am "a new update ${now}"
        git push 
    fi   
    )    
    echo "all done"
}
