Common Lisp Library for Pretty Printing? e.g. pretty print a nested hash table

Question

I am new to common lisp. Is there a CL library to pretty print collections, in my case, nested hash tables?

Answer 1

First, CL does not have a "collection" type.

Second, some (most?) CL implementations will print hash tables with content if you set *print-array* to t.

Third, if your CL implementation does not do that, you can easily whip up your own, based on, say, hash-table->alist.
