A simple Ruby method which returns an inspection string of the passed object with pretty indention ^^
def pretty_inspect(object, indent = 2)
if object.is_a?(Array)
entries = object.collect{|x| "#{pretty_inspect x, indent + 2}"}
pretty_indent entries, "[", "]", indent
elsif object.is_a?(Hash)
entries = object.keys.sort.collect{|x| "#{pretty_inspect x} => #{pretty_inspect object[x], indent + 2}"}
pretty_indent entries, "{", "}", indent
else
object.inspect
end
end
def pretty_indent(entries, open, close, indent)
if (s = "#{open}#{entries.join ", "}#{close}").size < 30
return s
end
entries.each_with_index{|x, i| entries[i] = "#{x}," if i < entries.size - 1}
[open, entries].flatten.join("\n" + (" " * indent)) + "\n" + (" " * (indent - 2)) + close
end
