NAME Text::Find::Scalar - Find scalar names in a text. VERSION version 0.10 SYNOPSIS use Text::Find::Scalar; my $finder = Text::Find::Scalar->new(); my $arrayref = $finder->find($string); # or $finder->find($string); while($finder->hasNext()){ print $finder->nextElement(); } DESCRIPTION This class helps to find all scalar variables in a text. It is recommended to use PPI to parse Perl programs. This module should help to find SCALAR names e.g. in error messages. Scalars that should be found: * double quoted "$foo" * references $foo->{bar} * elements of arrays $array[0] Scalars that are not covered * single quoted '$foo' EXAMPLE #!/usr/bin/perl use strict; use warnings; use Text::Find::Scalar; my $string = q~This is a $variable another $variable and another "$eine", but '$no' is not found. A $reference->{$key} is found. An array element $array[0] is also found~; my $finder = Text::Find::Scalar->new(); my @scalars = $finder->find($string); print $_,"\n" for(@scalars); prints /homes/reneeb/community>find_scalar.pl $variable $variable $eine $reference->{$key} $array[0] METHODS new my $finder = Text::Find::Scalar->new(); creates a new Text::Find::Scalar object. find my $string = q~Test $test $foo '$bar'~; my $arrayref = $finder->find($string); my @found = $finder->find($string); parses the text and returns an arrayref that contains all matches. hasNext while($finder->hasNext()){ print $finder->nextElement(); } returns 1 unless the user walked through all matches. nextElement print $finder->nextElement(); print $finder->nextElement(); returns the next element in list. unique my $uniquenames = $finder->unique(); returns an arrayref with a list of all scalars, but each match appears just once. count my $counter = $finder->count('$foo'); returns the number of appearances of one scalar.
