On to tackling this one. - Robert

Cool.

Have you looked at the generator starting point?

It doesn't matter to me if you use Ruby or Bash.

Also, there is a starting point on github for the templates folder.
Would like it to be divided into (all potential) server types:

templates/php/spec
/server
... etc.
/ruby/spec
./server
... etc.
/python/spec

.. etc

Then the generator script will copy from which ever server type you
speciied with an option. The default should be 'php' if none given.

BTW, I think there is one usecase for a Ruby server. You might want to
test on a different machine/environment. You might not want to lug
RSpec/Cucumber and all their dependencies over there. If you can
install spec_qire with dependencies for sinatra and json and
rest-client, you can rub the server there and run your specs and cukes
locally,

BTW, add sinatra as a gemspec dependency.

Cheers,
Ed

I don't think so. What is a "generator starting point"?

I've been going through the pickaxe book, reading about gems, and the
web, reading about rake:

I don't follow. Let's hook-up via IM/Skype sometime during the day on Tuesday.

What is a reasonable way to go about testing the gem? Should I try

Tried the LiveCD (Ubuntu 9.04 i386) in a VM approach and got this:

$ sudo gem install spec_wire-0.3.3.gem
Building native extensions. This could take a while...
ERROR: Error installing spec_wire-0.3.3.gem:

You need to make sure ruby-dev is installed via apt=get. I posted
about this in an earlier bit about my history file on 9.04

"I also had to : sudo apt-get install ruby1.8-dev"

However, I am not sure why it needs to build native extensions. Maybe
due to a dependency?

HTH,

That was it. Was able to build the gem and install it on a Ubuntu
LiveCD (see below).

I also added sinatra to the Jeweler::Task object in the rakefile.
Committed the rakefile to github. Updated the google group wiki page
to show how I installed the spec_wire gem. (at some point I need to
move the wiki page to github.)

Excellent!

Have you tried testing the spec_wire gem, once installed?

Easiest way to test would be to copy the exsiting spec_wire/templates
folder somewhere. Start the ruby_server in that folder's server dir.
Start irb with -rspec_wire. then:

Bar.new
Should get a Class Bar not found.

In another terminal in the templates location you copied:
echo 'class Bar; end' > server/bar.php

Then in irb:
obj = Bar.new
Should get back a valid object.

Nope. Don't get that. I get this:

$ rm servers/bar.*

$ ./bin/server.start
starting service

$ cat servers/ruby_server.pid

Hmm,

did you copy the templates folder somewhere else? If you did, then the
ruby server would be in 'server' not 'servers' and there would be no
bin dir at all (and no server_start script (there),

I am going to try the same sxperiment on my end.

Forgot one step. We need to load the spec_helper.rb only.

Here is my experiment:
mkdir rt
Mac:tmp$ cd rt
Mac:rt$ cp -r ~/ruby/spec_wire/templates/ .
Mac:rt$ ls
config server spec tmp
Mac:rt$ cat config/environment.rb
# environment.rb
# included from spec/spec_helper.rb

SpecWire::Initializer.run do |config|
config.class_cache =
File.join(File.expand_path(File.dirname(__FILE__)), '..', 'tmp',
'class_cache')
end

Mac:rt$ tree
.
|-- config
| `-- environment.rb
|-- server
| |-- ruby_server.rb
| `-- support
| |-- env.php
| `-- env.rb
|-- spec
| `-- spec_helper.rb
`-- tmp
`-- class_cache

6 directories, 5 files

Mac:rt$ cd spec/
Mac:spec$ irb -rspec_helper
irb(main):001:0> Bar.new
StandardError: class Bar not found
from /Users/edh/tmp/rt/config/../tmp/class_cache/bar.rb:14:in `rescue
in initialize'
from /Users/edh/tmp/rt/config/../tmp/class_cache/bar.rb:7:in `initialize'
from (irb):1:in `new'
from (irb):1
from /usr/local/bin/irb:12:in `<main>'

[.... this is where I echo'd the class file in another window ...]

irb(main):002:0> Bar.new
=> #<Bar:0x00000101700dd8 @meta={"json_class"=>"Bar", "data"=>[{}],
