popen'ing

November 7, 2007 — Leave a comment

I updated airake to work on windows (thanks Todd). Instead of using system (or %x), I am trying IO.popen:

IO.popen(@cmd) do |f|
  @output = f.read
  @process = Process.waitpid2(f.pid)[1]
end

and in windows you’ll need to cmd.exe /c it:

@cmd = RUBY_PLATFORM =~ /win32/ ? "cmd.exe /c #{cmd}" : cmd

This thread was helpful and I popened a new airake/runner.rb version. The FCSH daemon still doesn’t work in windows yet.

airake gives you tasks for compiling, debugging, testing and packaging Adobe AIR applications. It also has a basic project generator/scaffold. All this was made possible because of the prolific newgem and rubigen gems.

To get started, checkout airake.rubyforge.org

The tasks and project might be a little Flex specific (cause of the particular project we are working on), so feel free to poke around or contribute back. Also I only tested it on MacOSX.

Some of the FCSH (flex compiler shell) daemon and wrappers are from the Sprout project, so be sure to check them out.

I work on a very large rails project, and rake test has become unruly mostly due to the size of our codebase. Anyway, I wrote this task to run only the tests in the products/namespace I work on.

rake test:products PRODUCTS=product1,product2

Runs all unit tests in test/**/product1/*test*.rb, test/**/product2/*test*.rb

The task:

namespace :test do
  task :products do      
    raise "Usage: rake test:products PRODUCTS=product1,product2" if ENV['PRODUCTS'].blank?
    
    products = ENV['PRODUCTS'].split(/,/)
    files = []
    
    products.each do |product|
      dir = "#{RAILS_ROOT}/test/**/#{product}"
      files += FileList["#{dir}/*test*.rb"]
    end    
    
    test_task = Rake::TestTask.new("test_products") do |t|
      t.libs << "test"
      t.test_files = files
      t.verbose = true
    end
    
    task("test_products").execute           
  end
end

There is probably an easier way, but this works for me. Also I wouldn’t mind someone patching rake to accept opts style arguments, like –opt=blah, or -o blah. The ENV stuff seems really not so friendly.
