Inner assignment conditional is a pretty bad example...

[jtmarmon]

Why would you ever do

retval = if vals.any?
           do_something(vals)
         else
           do_something_different
         end

over

retval = vals.any? ? do_something(vals) : do_something_different

I think the inner assignment conditional only makes sense when more logic needs to be performed inside the conditions

Nice, @jtmarmon, we can put that in one line exactly. My point here was to show that we can also use

retval = if vals.any?
           do_something(vals)
         else
           do_something_different
         end

rather than:

if vals.any?
          retval =  do_something(vals)
 else
           retval = do_something_different
end

But, for sure it's best your solution in one line. What about we put the one line solution and also this solution? What do you think?

[jtmarmon]

Well I think you could best refine the page to - rather than focusing on specific examples - showing the multitude of ways you can be "lispy" in ruby (as ruby is quite lisp inspired).

Examples:

retval = if vals.any?
           do_something(vals)
         else
           do_something_different
         end

retval = case my_val
         when "foo"
           2
         when "bar"
           3
         else
           5
         end

retval = vals.any? ? do_something(vals) : do_something_different

retval = foo unless bar

etc. generally performing assignment on expressions that use first class operators. this was just a few off the top of my head. if you like the idea for the revision i'd be happy to PR it

[franzejr]

I liked the idea! I think the multitude of ways is nice! And we can have the one line and also those examples you did. Looking forward for your PR.

Thanks! :+1:

[jtmarmon]

on it. any ideas for the title of the article?

[franzejr]

My idea at the beginning it was "inner assignment", because I would like to remove the assignment inside my conditional. Since, we are still working with assignments, conditionals and we're trying to do the same thing... Why not keep the title or something like "Conditional Assignments" ?

[jtmarmon]

yeah i like it

:+1: looking forward for your PR!
