Re: [PATCH] Yet another tree dumper

Why? The example Devang gave looks just as messy as the current dumper,

If you use 90 char wide window then it you'll see it uses much better indentation scheme. And it adds empty lines also appropriately.

I only posted this patch, because people showed interest earlier...
[ see  thread]

Let's look at another example example functions with parameters.
