Module: Puppet::Pops::Patterns

Defined in:

lib/puppet/pops/patterns.rb

Overview

The Patterns module contains common regular expression patters for the Puppet DSL language

Constant Summary

NUMERIC =

NUMERIC matches hex, octal, decimal, and floating point and captures three parts 0 = entire matched number, leading and trailing whitespace included 1 = hexadecimal number 2 = non hex integer portion, possibly with leading 0 (octal) 3 = floating point part, starts with “.”, decimals and optional exponent

Thus, a hex number has group 1 value, an octal value has group 2 (if it starts with 0), and no group 3 and a floating point value has group 2 and group 3.

%r{^\s*(?:(0[xX][0-9A-Fa-f]+)|(0?\d+)((?:\.\d+)?(?:[eE]-?\d+)?))\s*$}

ILLEGAL_HOSTNAME_CHARS =

ILLEGAL_P3_1_HOSTNAME matches if a hostname contains illegal characters. This check does not prevent pathological names like ‘a.…b’, ‘.….’, “—”. etc.

%r{[^-\w.]}

NAME =

NAME matches a name the same way as the lexer.

%r{\A((::)?[a-z]\w*)(::[a-z]\w*)*\z}

CLASSREF_EXT =

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. This name includes hyphen, which may be illegal in some cases.

%r{\A((::){0,1}[A-Z][\w]*)+\z}

CLASSREF =

CLASSREF matches a class reference the way it is represented internally in the model (i.e. in lower case). This name includes hyphen, which may be illegal in some cases.

%r{\A((::){0,1}[a-z][\w]*)+\z}

DOLLAR_VAR =

DOLLAR_VAR matches a variable name including the initial $ character

%r{\$(::)?(\w+::)*\w+}

VAR_NAME =

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.

%r{\A(:?(::)?[a-z]\w*)*(:?(::)?[a-z_]\w*)\z}

NUMERIC_VAR_NAME =

A Numeric var name must be the decimal number 0, or a decimal number not starting with 0

%r{\A(?:0|(?:[1-9][0-9]*))\z}
