"Just an extended Rake."

Ouch. Pardon me while I extract this dagger from my heart. ;)

I'm confused that Capistrano doesn't use any of Rake's code as they
seem so close in many ways. I thought Cap was just an extended Rake.
No matter either way of course :)

I'll raise a ticket in the next few days.

Adam,

I know Rake has added support for parameterized tasks in the last
year or so. Capistrano doesn't reuse any of Rake's code, but
perhaps it's implementation of the feature might prove
inspirational. As ever, if you want something bad enough, the
quickest way to see it find its way into capistrano is via a patch.

Ok. I guess that will have to do (not much choice :).

Seems like a workable solution

what might be nice, just thinking about it would be something like:

cap upload(dir_a, dir_b, dir_c)

I know cap depends on rake (and I think i'm in the minority) but
still a thought.

this would also allow

cap deploy(production)

Capistrano interprets all bare arguments as tasks to be executed.
The multistage extension makes this work by defining tasks for each
stage, so that "cap production deploy" first calls the "production"
task, and then calls "deploy".

If you want to pass parameters to your tasks, you can do it via
environment variables:

  cap upload FILES=dir_a,dir_b,dir_c

Then, your upload task gets the FILES env var, parses it, and
processes the directories as needed:

  task :upload do
    files = ENV['FILES'].split(/,/)
    # ...
  end

OK, Here's the problem...
I'm using Cap as a basic shell script replacement (I don't use SCM
etc) I like that it gives you descriptions and namespaces and such
for
tasks, and it's all going swimmingly - except...
I'd like to be able to read the arguments off the command into an
array...

cap upload dir_a dir_b dir_c


from the command line, so it should be possible.

If i just execute the above as is, I get a "task dir_a not
found" (although I can still use the arguments with ARGV[]).

TIA,

I know that the capistrano multistage extension reads several items
