I use Brett Terpstra's doing for logging what I do throughout the day.

This repo contains my configuration files, shell aliases, and the Alfred Workflow I use.

Check doing's installation instructions, but I installed HEAD using...

gem install --pre doing

I also use a few shell aliases...

alias dn="doing now"
alias d="doing"
alias dt="doing today"
alias dy='d yesterday | cut -d " " -f 2- | sed -e "s/^/ /"'
alias idea="doing now -s Sparks"

There's also an Alfred workflow for when I'm not in a terminal. Using Alfred I can hit CTRL-SPACE, then dn This is what I am doing now and "This is what I am doing now" will be added to my doing file.

#Other tools

doing2dayone collects doing's entries from yesterday and adds them to a Day One entry in my "Daybook" journal
