User profile extension that allows you to execute "subl" in a project's root folder and have it automatically open the project file if such a file exists. This script looks in the current directory and in a hard coded location in case that's where you store all your project files.

# sublime text alias
function project_aware_subl() {
    current_directory=${PWD##*/}

    result=$(ls *.sublime-project 2>/dev/null | head -n 1)

    if [ -z $result ]; then
        result=$(ls ~/Documents/Sublime/${current_directory}.sublime-project 2>/dev/null | head -n 1)
        result=$(printf '%q' "$result")
  
        if [[ $result == "''" ]]; then
            unset result
        else
            echo "opening project.."
        fi
    else
        echo "opening project.."
    fi

    subl ${*:-${result:-.}}
}
alias subl="project_aware_subl"

This script requires that the subl sym link already exists:

sudo ln -s "/Applications/Sublime Text 2.app/Contents/SharedSupport/bin/subl" /usr/bin/subl
