# The Patterns module contains common regular expression patters for the Puppet DSL language
module Puppet::Pops::Patterns
# NUMERIC matches hex, octal, decimal, and floating point and captures several parts
# 0 = entire matched number, leading and trailing whitespace and sign included
# 1 = sign, +, - or nothing
# 2 = entire numeric part
# 3 = hexadecimal number
# 4 = non hex integer portion, possibly with leading 0 (octal)
# 5 = floating point part, starts with ".", decimals and optional exponent
#
# Thus, a hex number has group 3 value, an octal value has group 4 (if it starts with 0), and no group 3
# and a floating point value has group 4 and group 5.
#
NUMERIC = %r{\A[[:blank:]]*([-+]?)[[:blank:]]*((0[xX][0-9A-Fa-f]+)|(0?\d+)((?:\.\d+)?(?:[eE]-?\d+)?))[[:blank:]]*\z}
# ILLEGAL_P3_1_HOSTNAME matches if a hostname contains illegal characters.
# This check does not prevent pathological names like 'a....b', '.....', "---". etc.
ILLEGAL_HOSTNAME_CHARS = %r{[^-\w.]}
# NAME matches a name the same way as the lexer.
NAME = %r{\A((::)?[a-z]\w*)(::[a-z]\w*)*\z}
# CLASSREF_EXT matches a class reference the same way as the lexer - i.e. the external source form
# where each part must start with a capital letter A-Z.
#
CLASSREF_EXT = %r{\A((::){0,1}[A-Z][\w]*)+\z}
# CLASSREF matches a class reference the way it is represented internally in the
# model (i.e. in lower case).
#
CLASSREF = %r{\A((::){0,1}[a-z][\w]*)+\z}
# DOLLAR_VAR matches a variable name including the initial $ character
DOLLAR_VAR = %r{\$(::)?(\w+::)*\w+}
# VAR_NAME matches the name part of a variable (The $ character is not included)
# Note, that only the final segment may start with an underscore.
VAR_NAME = %r{\A(:?(::)?[a-z]\w*)*(:?(::)?[a-z_]\w*)\z}
# A Numeric var name must be the decimal number 0, or a decimal number not starting with 0
