To view the coverage of your plugins using Rcov, first install the rcov gem with sudo gem install rcov, then copy and paste the following onto the end of the Rakefile inside your plugin directory:

desc 'Measures test coverage using rcov'
task :rcov do
  rm_f "coverage"
  rm_f "coverage.data"
  rcov = "rcov --rails --aggregate coverage.data --text-summary -Ilib"
  system("#{rcov} --html #{Dir.glob('test/**/*_test.rb').join(' ')}")
  system("open coverage/index.html") if PLATFORM['darwin']
end

You can now simply run rake rcov from inside your plugin directory which will generate a coverage directory with the results. Open coverage/index.html (if you are on OSX this will open automatically) in a browser to view the results.

Thanks to Mike Clark for his Rcov rake task for Rails which this task is based on.

John Nunemaker posted a handy tip on setting up autotest to work with Growl

I use this all the time now however I didn’t like the ugly smilies (call me shallow if you like). I used Wolfgang Bartelme’s Smily Devkit to make a couple of PNG’s slightly more pleasing to the eye.

Update 17-08-07: Added ‘pending’ image for RSpec as requested by Aslak Hellesøy

Following my previous post, below is a modified version of John Nunemaker’s ‘Renaming RHTML to ERB’ to take into account the format in the extension, and handle the RJS issues I was having.

namespace 'views' do
  desc 'Renames all .rhtml views to .html.erb, .rjs to .js.rjs, .rxml to .xml.builder and .haml to .html.haml'
  task 'rename' do
    Dir.glob('app/views/**/[^_]*.rhtml').each do |file|
      puts `svn mv #{file} #{file.gsub(/\.rhtml$/, '.html.erb')}`
    end

    Dir.glob('app/views/**/[^_]*.rjs').each do |file|
      puts `svn mv #{file} #{file.gsub(/\.rjs$/, '.js.rjs')}`
    end

    Dir.glob('app/views/**/[^_]*.rxml').each do |file|
      puts `svn mv #{file} #{file.gsub(/\.rxml$/, '.xml.builder')}`
    end

    Dir.glob('app/views/**/[^_]*.haml').each do |file|
      puts `svn mv #{file} #{file.gsub(/\.haml$/, '.html.haml')}`
    end
  end
end

Update

Added haml conversion.

I have found on numerous occasions that I need to disable certain plugin functionality if running a generator / rake db:migrate etc.

An easy way to disable certain functionality follows:

def method_that_shouldnt_be_run_in_migrations_or_generators
  # Return if we are using a generator or migrations
  script = File.basename($0)
  return if (script == 'generate') || (script == 'rake' && ARGV[0] =~ /migrate$/)
end

Just read a post from David at Planet Argon showing a way to add un-added files in your Subversion working copy.

namespace :svn do
  desc "Adds all files with an svn status flag of '?'"
  task(:add_new) { `svn status | awk '/\\?/ {print $2}' | xargs svn add` }
end

Just drop this code in a file called subversion.rake inside the tasks directory. Now you can run rake svn:add_new which will add all new files with an svn status flag of ’?’ in your working copy.
