regex to split on ' ', but skip spaces inside quotes

true_atlantis has asked for the wisdom of the Perl Monks concerning the following question:

is there a way to do a split regular expression which will split on space, unless the space is in between quotes? for example:

hi my name is 'john doe'

would parse to:
hi
my
name
is
'john doe'

thanks!

    use quotewords from Text::ParseWords
    use Text::ParseWords qw(quotewords); my $line = q(hi my name is 'john doe'); @words =quotewords(' ', 0, $line); print join "\n", @words,"\n";

    Rather than thinking in terms of "splitting on spaces", may be it would work better if you thought in terms of "gather the things I want". For instance, would this work for you:

    #!/usr/bin/perl use strict; use warnings; my $string = q(hi my name is 'john doe'); my @parts = $string =~ /'.*?'|\S+/g; print map { "$_\n" } @parts; __END__

    my @words= $string =~ /'[^']*'|\S+/g; my @words= $string =~ /'(?:\\.|[^\\']+)*'|\S+/gs; my @words= $string =~ /'(?:''|[^']+)*'|\S+/g;
