( [id://3333]=superdoc: print w/replies, xml ) Need Help??
Hey guys
Consider the following string: "a,b,c,d,5"
The format of the string is like this: "substr,substr,substr,...,value"
I use regex to check the string:

my ($value) = ($row =~ /.*,(.*)/); # gets value after the last comma if (looks_like_number($value)) { ($row =~ s/,[^,]*$//); # gets substring before the last comma # DO STUFF ... } # DO STUFF ...
It works fine but it doesn't look very good.
I cant understand why in my ($value) = ($row =~  /.*,(.*)/); I need the brackets on the scalar but in ($row =~ s/,[^,]*$//); I don't need.
In other words, why is there is a syntax difference between the following two lines:

my ($value) = ($row =~ /.*,(.*)/); my ($val) = ($row =~ s/,[^,]*$//);


Testing: my $row = "a,b,c,d,15";
Output of first line: 15
Output of second line: 1 (why not a,b,c,d?)
How to do it in the same way?

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
