Create and edit an octopress post from anywhere (and avoid zsh globbing issues)

new-post.zsh

#!/bin/zsh

# export BLOG="/path/to/your/octopress/install"

# handles globbing weirdness with zsh + use it from anywhere
# use: new-post "This is my exciting new post!!!"
# set the blog variable to your octopress directory
# TODO: fix this so it handles double-titling

function new-post () {
    echo "Creating a new_post titled '$1'."
    cd $BLOG/
    newpost=$(bundle exec rake "new_post[$1]" | awk '{print $4}')
    $EDITOR $BLOG/$newpost
}
