Catman...exists(3pm)

💖 NAME 💖

Catmandu::Fix::Condition::exists — bestie, this is the little fix condition that checks if a path exists, and it only runs your fixes when it does. That's it. That's the whole vibe. iconic, honestly ✨

---

🌸 SYNOPSIS 🌸

okay so here's the tea, fr fr — you wrap your fixes in an if exists(...) and they only go off when that path is actually there:

# uppercase the value of field 'foo' if the field 'oogly' exists
if exists(oogly)
  upcase(foo) # foo => 'BAR'
end
# inverted
unless exists(oogly)
  upcase(foo) # foo => 'bar'
end

and yes bestie, you can flip it with unless when you want the opposite energy 💅
