# Subject: Compound conditionals in case when statements? Syntax?

# I need (or want ;-) to do something like the following:
# when ((/^---\+\+ (.*)/) and (new_record == true))

cases come in two forms,

1 classic switch form, like
  
  case sw
  when foo
    #..
  when bar
    #..
  else
    #..
  end

  this form is interpreted using if is like (as already explained by mentalguy),

  if foo===sw
     #..
  elsif bar===sw
     #..
  else
     #..
  end


2 conditional form (similar to nested ifs), like

  case
  when foo
     #...
  when bar and condition1
     #...
  when condition2 or condition3
     #..
  else
     #..
  end

  this form is interpreted using if like,

  if foo
     #..
  elsif bar and condition1
     #..
  elsif condition2 or condition3
     #..
  else
     #..
  end

I would reckon fr your post that you may want the second form. So something like,

  case
  when ((/^---\+\+ (.*)/) and new_record
     #..
  end

But i'm not totally sure since you didn't post any sample code.  but hey, if your code does not fit the cases, then by all means, do the ifs..

hth.
