New CSL Arduino Posting

A couple of quick notes - at the suggestion of a friend, I’ve written some posts for the Citizen Scientists League on the Arduino weather station. Code, setup, circuitry, Pachube interface and such. I’m curious to see how the response is there, as they probably get more readers than I do here.

Secondly, a quick tweak to Octopress - when you create a new post using rake, I added calls to add the post to git and fire up the editor, as those are what I’d do next anyway. Here’s the snippet from the Rakefile:

# usage rake new_post[my-new-post] or rake new_post['my new post'] or rake new_post (defaults to "new-post")
desc "Begin a new post in #{source_dir}/#{posts_dir}"
task :new_post, :title do |t, args|
  raise "### You haven't set anything up yet. First run `rake install` to set up an Octopress theme." unless File.directory?(source_dir)
  mkdir_p "#{source_dir}/#{posts_dir}"
  args.with_defaults(:title => 'new-post')
  title = args.title
  filename = "#{source_dir}/#{posts_dir}/#{Time.now.strftime('%Y-%m-%d')}-#{title.to_url}.#{new_post_ext}"
  if File.exist?(filename)
    abort("rake aborted!") if ask("#{filename} already exists. Do you want to overwrite?", ['y', 'n']) == 'n'
  end
  puts "Creating new post: #{filename}"
  open(filename, 'w') do |post|
    post.puts "---"
    post.puts "layout: post
comments: true"
    post.puts "title: \"#{title.gsub(/&/,'&')}\""
    post.puts "date: #{Time.now.strftime('%Y-%m-%d %H:%M')}"
    post.puts "comments: true"
    post.puts "categories: "
    post.puts "---"
  end
  # pfh 2/10/12
  system "git add #{filename}"
  system "edit #{filename}"
end

One more note - if you use zsh, you have to escape the square brackets. Here’s the syntax when I created this post:

1

rake new_post\["New CSL Arduino posting"\]

Mildly annoying.
