NAME

Perl::Review::Utils - Utility subs and vars for Perl::Review

DESCRIPTION

This module has exports several static subs and variables that are useful for developing Perl::Review::Policy subclasses. Unless you are writing Policy modules, you probably don't care about this package.

EXPORTED VARIABLES

@BUILTINS

This is a list of all the built-in functions provided by Perl 5.8. I imagine this is useful for distinguishing native and non-native function calls. In the future, I'm thinking of adding a hash that maps each built-in function to the maximal number of arguments that it accepts. I think this will help facilitate the lexing the children of PPI::Expression objects.

@GLOBALS

This is a list of all the magic global variables provided by the English module. Also includes commonly-used global like %SIG, %ENV, and @ARGV. The list contains only the variable name, without the sigil.

$COMMA

$COLON

$SCOLON

$QUOTE

$DQUOTE

$PERIOD

$PIPE

$EMPTY

These give clear names to commonly-used strings that can be hard to read when surrounded by quotes.

$TRUE

$FALSE

These are simple booleans. 1 and 0 respectively. Be mindful of using these with string equality. $FALSE ne $EMPTY.
