In order to fix the "single space delimiter" issue in your output, you can define "at least 2 space characters" eg [\s]{2,}
as delimiter which would fix the issue for St. Elf
in City names

QUESTION
Greg Pfeil's Class Hierarchy diagram provides a comprehensive picture the Common Lisp type system. But I'm trying to better understand the class relationships at the top of the hierarchy. For a simple example, let (defstruct person name age)
, and then (defparameter *p1* (make-person :name "Yosh" :age 19)
. Now
ANSWER
Answered 2017-Feb-28 at 16:52All classes are types, but not all types are classes. Some types are defined in terms of other types. An atom is anything that's not a cons. Since an instance of a structure isn't a cons, it's an atom. From the HyperSpec:
Supertypes:
atom, t
Description:
It is equivalent to
(not cons)
.
As another common example, consider the type list, which is equivalent to (or null cons). NIL (of type null) is a list, and a cons is a list. That's it.
Neither atom nor list are classes, but they are types.
Because we can have complement types and union types and intersection types, the concept of type hierarchies gets a bit more complicated, even if there are still proper class hierarchies.
The Hyperspec says the precedence list for structure-object is only itself and t. Are atom and structure not types in the hierarchy?
That's not quite what the HyperSpec says. The HyperSpec says that t is a supertype of structure-type. In Common Lisp, you can define arbitrary new types. E.g., with a simple (deftype my-new-type (or structure-object list)), you'd have (typep *p1* 'my-new-type) return true as well. That doesn't suddenly invalidate what the HyperSpec says about the class precedence of structure-object.
By analogy with set theory, it would seem that all Common Lisp types/classes could theoretically be subdivided into two subclasses of t
That would be one way of doing it, but because of the ability to define new types in terms of union of types, intersection of types, and complements of types, there are many ways that you could partition the objects of Common Lisp by type.

Install yosh
You can use yosh like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
