In the command line syntax for sass/compass it is possible to pass the environment variable.

compass compile -e=production

A small change to the config.rb will allow the system to set this flag based upon the switch.

# Default to development if environment is not set.
saved = environment
if (environment.nil?)
  environment = :development
else
  environment = saved
end

Above will allow you to use the switch to change the environment variable.

Here is a patch

This complicates the text in the config.rb file and I couldn't get it to work.

I also tried environment ||= :development with no luck.

Status:Needs review» Needs work

also unable to get this to work

Why even bother? Just use "compass compile -e production --force" :)

Status:Needs work» Closed (works as designed)

Didn't know about the --force option.

Works for me! :-)

Status:Closed (works as designed)» Needs review

I have done some more tests. I create a competely new zen subtheme with this patch applied.

As it is now, when I run the following command

$ compass compile -e production --force

I get the following output for the block.css. Also note I have turned on firesass to high light this more.

Where as when I apply the patch I have provide the block.css compiles to

.block{margin-bottom:1.5em}

As you can see without the patch the css is being created using development mode.

I have put this back to "needs review" because without the patch the enviroment variable can't be altered from the command line without the above patch.
