[Capistrano] Re: Can passing in variables override Capistrano::CLI.ui.ask?

[Jamis Buck]

Yes. Using the "-s" switch, any variable you set that way will override any variables with the same name that were set in the recipe file.

Hey all,

Just one more quick question.

Is it possible to prompt the user for a variable only if they haven't
provided that variable on the command line?

Essentially what I'd like to do is allow a user to do something like

<pre>cap -s scm_username=a_user deploy</pre>

If they pass in the variable, we use it and don't prompt them for
anything.  However if they just run:

<pre>
cap deploy
</pre>

then they will be prompted with

"Enter your SVN username"

Is this possible?

Any help would be appreciated.
