# - \x was removed from simple_escape, unless it was not followed by a hex digit, to avoid ambiguity with hex_escape.
# - hex_escape allows one or more hex characters, but requires that the next character(if any) is not hex
# - decimal_escape allows one or more decimal characters, but requires that the next character(if any) is not a decimal
# - bad_escape does not allow any decimals (8-9), to avoid conflicting with the permissive decimal_escape.
#
# Without this change, python's `re` module would recursively try parsing each ambiguous escape sequence in multiple ways.
# e.g. `\123` could be parsed as `\1`+`23`, `\12`+`3`, and `\123`.

# To understand what's going on here, read sections A.8.5 and

#
# A C type consists of a basic type declaration, with a list
# of modifiers. For example:
#
# int *c[5];
#
# The basic declaration here is 'int c', and the pointer and
# the array are the modifiers.
#
# Basic declarations are represented by TypeDecl (from module c_ast) and the
# modifiers are FuncDecl, PtrDecl and ArrayDecl.
#
# The standard states that whenever a new modifier is parsed, it should be
# added to the end of the list of modifiers. For example:
#
# K&R2 A.8.6.2: Array Declarators
#
# In a declaration T D where D has the form
# D1 [constant-expression-opt]
# and the type of the identifier in the declaration T D1 is
# "type-modifier T", the type of the
# identifier of D is "type-modifier array of T"
#
# This is what this method does. The declarator it receives
# can be a list of declarators ending with TypeDecl. It
# tacks the modifier to the end of this list, just before
# the TypeDecl.
#
# Additionally, the modifier may be a list itself. This is
# useful for pointers, that can come as a chain from the rule
# p_pointer. In this case, the whole modifier list is spliced
# into the new location.

# This implements an LR parser that is constructed from grammar rules defined
# as Python functions. The grammer is specified by supplying the BNF inside
# Python documentation strings. The inspiration for this technique was borrowed
# from John Aycock's Spark parsing system. PLY might be viewed as cross between
# Spark and the GNU bison utility.
#
# The current implementation is only somewhat object-oriented. The
# LR parser itself is defined in terms of an object (which allows multiple
# parsers to co-exist). However, most of the variables used during table
# construction are defined in terms of global variables. Users shouldn't
# notice unless they are trying to define multiple parsers at the same
# time using threads (in which case they should have their head examined).
#
# This implementation supports both SLR and LALR(1) parsing. LALR(1)
# support was originally implemented by Elias Ioup ([email protected]),
# using the algorithm found in Aho, Sethi, and Ullman "Compilers: Principles,
# Techniques, and Tools" (The Dragon Book). LALR(1) has since been replaced
# by the more efficient DeRemer and Pennello algorithm.
#
# :::::::: WARNING :::::::
#
# Construction of LR parsing tables is fairly complicated and expensive.
# To make this module run fast, a *LOT* of work has been put into
# optimization---often at the expensive of readability and what might
# consider to be good Python "coding style." Modify the code at your
# own risk!

Persistent map/dict. Tries to follow the same naming conventions as the built in dict where feasible.
Do not instantiate directly, instead use the factory functions :py:func:`m` or :py:func:`pmap` to
create an instance.
Was originally written as a very close copy of the Clojure equivalent but was later rewritten to closer
re-assemble the python dict. This means that a sparse vector (a PVector) of buckets is used. The keys are
hashed and the elements inserted at position hash % len(bucket_vector). Whenever the map size exceeds 2/3 of
the containing vectors size the map is reallocated to a vector of double the size. This is done to avoid
excessive hash collisions.
This structure corresponds most closely to the built in dict type and is intended as a replacement. Where the
semantics are the same (more or less) the same function names have been used but for some cases it is not possible,
for example assignments and deletion of values.
PMap implements the Mapping protocol and is Hashable. It also supports dot-notation for
element access.
Random access and insert is log32(n) where n is the size of the map.
The following are examples of some common operations on persistent maps
>>> m1 = m(a=1, b=3)

"""
Persistent vector implementation. Meant as a replacement for the cases where you would normally
use a Python list.
Do not instantiate directly, instead use the factory functions :py:func:`v` and :py:func:`pvector` to
create an instance.
Heavily influenced by the persistent vector available in Clojure. Initially this was more or
less just a port of the Java code for the Clojure vector. It has since been modified and to
some extent optimized for usage in Python.
The vector is organized as a trie, any mutating method will return a new vector that contains the changes. No
updates are done to the original vector. Structural sharing between vectors are applied where possible to save
space and to avoid making complete copies.
This structure corresponds most closely to the built in list type and is intended as a replacement. Where the
semantics are the same (more or less) the same function names have been used but for some cases it is not possible,
for example assignments.
The PVector implements the Sequence protocol and is Hashable.
Inserts are amortized O(1). Random access is log32(n) where n is the size of the vector.
The following are examples of some common operations on persistent vectors:
>>> p = v(1, 2, 3)
>>> p2 = p.append(4)
>>> p3 = p2.extend([5, 6, 7])
>>> p
pvector([1, 2, 3])

pvector([1, 2, 3, 4])

pvector([1, 2, 3, 4, 5, 6, 7])

Create a new evolver for this pvector. The evolver acts as a mutable view of the vector
with "transaction like" semantics. No part of the underlying vector i updated, it is still
fully immutable. Furthermore multiple evolvers created from the same pvector do not
interfere with each other.
You may want to use an evolver instead of working directly with the pvector in the
following cases:
* Multiple updates are done to the same vector and the intermediate results are of no
interest. In this case using an evolver may be a more efficient and easier to work with.
* You need to pass a vector into a legacy function or a function that you have no control
over which performs in place mutations of lists. In this case pass an evolver instance
instead and then create a new pvector from the evolver once the function returns.
The following example illustrates a typical workflow when working with evolvers. It also
displays most of the API (which i kept small by design, you should not be tempted to
use evolvers in excess ;-)).
Create the evolver and perform various mutating updates to it:
>>> v1 = v(1, 2, 3, 4, 5)
>>> e = v1.evolver()
>>> e[1] = 22
>>> _ = e.append(6)
>>> _ = e.extend([7, 8, 9])
>>> e[8] += 1
>>> len(e)
9
The underlying pvector remains the same:
>>> v1
pvector([1, 2, 3, 4, 5])
The changes are kept in the evolver. An updated pvector can be created using the
persistent() function on the evolver.
>>> v2 = e.persistent()
>>> v2
pvector([1, 22, 3, 4, 5, 6, 7, 8, 10])

Persistent double ended queue (deque). Allows quick appends and pops in both ends. Implemented
using two persistent lists.
A maximum length can be specified to create a bounded queue.
Fully supports the Sequence and Hashable protocols including indexing and slicing but
if you need fast random access go for the PVector instead.
Do not instantiate directly, instead use the factory functions :py:func:`dq` or :py:func:`pdeque` to
create an instance.
Some examples:
>>> x = pdeque([1, 2, 3])
>>> x.left
1
>>> x.right
3
>>> x[0] == x.left
True
>>> x[-1] == x.right
True

## Introduction
This extension is used purely for holding tests for omni.kit.property.usd, that need to show a real window during automated tests. Mostly this is because the clipboard copy and paste code needs to have an actual window.

It only works for Cone/Cylinder/Cube.

w_verts_scale (int): Tessellation Level of W. It's a multiplier of w_patches.
It only works for Cone/Cylinder/Cube.
For Cone/Cylinder, it's to tessellate the caps.
For Cube, it's to tessellate along z-axis.
