parse options with values

From:: Lee Capps

Hi,

I've been working on a formula [1] which requires options with values, e.g.

brew install plod --cryptcmd=bcrypt

I got feedback that options of that form (using '=') break 'brew
audit'. They don't break my 'brew audit', but okay -- I gather they
should, or at least that the preferred style would be something like

brew install plod --cryptcmd bcrypt

But I can't seem to get the latter to work, as bin/brew assumes the
values for my options are formulae and shifts them out of ARGV. So how
should I handle this? Could anyone point me to other formulae that use
options w/ values?

Thanks!

        Seems like bin/brew should be fixed.Or fix audit.Or do --bcryptcmd
or something.But yes basically stuff needs fixing.

Or perhaps this is rarely needed and not worth worrying about?

In my case, I've decided I was going about it wrong. The tool I'm
installing supports an RC file (though I'd never used one before), so
I've updated my formula[1] to make some educated guesses based on ENV
and then facilitate use of a user-edited RC file.

Thanks for the reply.
