in thread Parsing "=" separated output


I've modified the regexp a bit, so that the concatenation is no longer necessary

while ( $string =~ m/\s+([^\s]+?)=(.*?)(?=\s[^\s]+=|$)/g )

Works quite well.

    Same idea but taking advantage of the wantarray response of a match and commenting the regex
    ~/$ perl -e ' $string="sometrash key1=value0 value1, value2 key2=value3 key3=value4" +; %hash = $string =~/ (\w+) #capture the key name = # separated from the value by an equals (.+?) # and then the value, non-greediness prevents running + into the subsequent values (?=(?:\s\w+=|$)) # finally we look ahead to ensure that what follows i +s a space and a "key=" pattern, or else the end end of the string /xg; #Match globally and allow comments in the regex for m +aintainability # And check use Data::Dumper;print Dumper(\%hash); ' $VAR1 = { 'key2' => 'value3', 'key1' => 'value0 value1, value2', 'key3' => 'value4' };
    print "Good ",qw(night morning afternoon evening)[(localtime)[2]/6]," fellow monks."
